CHAPTER 1 (Saturday, Nov. 9)

Alan took advantage of the weekend and slept twelve hours. When he woke up the next morning, after nine o'clock, he felt like a new man. And it was a lucky thing, too, because after having gone merely four times a day for two days in a row, the women were all keen to make sure he would have an extra-active day to make up for it.

Susan cooked her son breakfast, but when she was done she had to leave to run some errands. Katherine was still asleep from having gone to bed much later, and Suzanne hadn't come over yet for the same reason.

But right as Susan made to leave, Amy came over. She told Amy that Alan's penis was extremely sad and that she should help "visually stimulate" it.

Amy clapped her hands in glee. Once Susan was gone, she hurried home and immediately came back with something scanty to wear. She used the underwear cabinet to change, as usual. Her outfit, if it could be called that, was a robe that failed to even come down to her pussy and exposed her shaven folds to anyone who cared to look. It used to be much longer, but she'd shortened it to a very strategically sexy length.

Amy walked into the dining room where Alan was still eating breakfast. He took a look at her and nearly choked on his French toast. "Amy," he sputtered, "quick, you'd better change out of that."

"What? You don't like it? I made it especially short, just for you."

"That was very nice of you. I think it's great. But my mom's just gone shopping for groceries and she'll be back soon. She'll have a hissy fit if she sees you like that."

Amy smiled happily. "No she won't. I'm sure of it because she's the one who told me to wear this. She told me you weren't being stimulated enough in the past couple of days and that I was supposed to stimulate you."

Alan nearly choked on his food again. "She said that? She told you that you could stimulate me? Did she say how? Like with your hands or mouth or something?"

"No. She just said you needed a lot of stimulation today. I'm the only one around to help, I guess." Amy purposely failed to mention that Susan only meant visual stimulation. She twirled around. The robe was cut even shorter in the back. More than half of her ass was exposed. Alan's eyes went wider in response. She noticed his happy reaction, and turned around again, making sure to bend over lewdly this time. With both hands wrapped tightly around one of her ankles, she winked at Alan as she looked him, upside down, from between her legs.

Alan rapidly stuffed his food down his mouth so his hands could be freed. "Stay like that," he said as he unconsciously licked his lips.

"M'kay," she answered happily as she thrust her naked ass further up towards where he sat. She reached her left hand up to her pussy and absent-mindedly rubbed her lips as she added, "Gee, I never realized how cold this house can be sometimes. Do you feel a breeze?"

Then Alan thought to himself, How strange. But then what isn't strange lately? Mom did say last night that she expected a big orgasm day from me today, but why would she include Amy? I thought she was protective of her, just like Suzanne is. But should I look a gift horse in the mouth? Or, more appropriately, a gift horse in the ass. What a lovely ass. How am I supposed to say no to that ass? ... Actually, now that I think about it, the other day Mom did say that nothing should be denied me. That was in relation to Brenda, but surely if she felt that way about Brenda, she feels the same about Amy?

Alan finished off his last bite and put his silverware down. He reached out and grabbed Amy's ass. He said to her, "If you're going to stimulate me, you're doing a good job already. But do you remember what I told you before, about the three parts of the female a man likes the best?"

She giggled as she once again grabbed hold of her ankles while Alan gently massaged her perfect derriere. "Gosh. That's easy. The boobies, the puss, and the ass. Everyone knows that."

He ran his fingers up and down her ass crack, and didn't hesitate to probe her pussy lips. "Yeah. This outfit is good at showing off two of those, but let's see some more of your boobs."

She turned around and undid the sash of her robe. She opened the robe but only on one side as she tilted her hip in the opposite direction and struck a seductive pose. "You mean like this?" she asked coyly, her voice high and airy.

"Oooh, I like it. Yeah. Just like that. Showing a little, but still hiding a little, leaving me wanting more. And you've pushed your boobs together with your arms and given me a sultry look on top of it. You're really getting good at visual stimulation."

She wanted to keep her sultry look going, but couldn't help but break out into a shy smile. Fortunately, the shy grin made her look even sexier.

"Now, let's see if you need another pussy shaving today." Alan reached out and fondled her pussy and tits, occasionally working on her ass.

Amy just stood there with a big smile on her face, happy to let him touch her anywhere.

He was still at it when Katherine walked downstairs a couple of minutes later. She said, as she walked into the dining room, "Looks like I'm missing out on some fun, Big Super Dildo-sized Brother. Maybe you should give me a good spanking for sleeping in too late and neglecting my sisterly duties." She winked at her purposeful reminder of the spanking she had the night before. "Where's Mom?"

"Off to buy some groceries," Alan replied. "Amy here says she was left behind as a kind of gift to occupy me in the meanwhile."

Katherine's eyebrows were raised in surprise. "Whoa. Our new mom is full of surprises, isn't she? Let's see if Amy needs another shaving." Katherine moved in on Amy and began to fondle her, too. Alan instantly understood her meaning of "new mom" - it was as though Susan had become a completely different person in recent weeks, although many aspects remained the same, of course.

Alan laughed. "Hey, I was using that pussy, Sis." Amy writhed in pleasure as four hands roamed all over her. Her robe stayed on, but only because it didn't get in the way of access to any important parts.

After another wordless minute of this, Amy said, "You know guys, I most definitely need a shaving. Right away. I'm getting all tingly. Please help!"

Katherine pointed out, "Hey, Big Sister-filling Brother, it's been too long since we've done her together. You should see the things the two of us girls have been doing lately in these shavings."

Amy butted in with the proud mention, "Katherine says I'm a good ass licker!"

Katherine clarified, "She means that in the good, literal way."

Alan chuckled. "Why don't we give the shaving a shot, and that'll give us some cover to make sure we interpreted Mom correctly."

"Oh goody!" Amy exclaimed. "Alan, can I lick your butt?"

They took Amy's robe off and led her to the bathroom. The first thing Alan did was explain that he didn't feel happy. Amy would have to stroke his thing to make him happy again. She already knew that and was eager to help. She was pleased to see his penis had rebounded from yesterday.

CHAPTER 2

Alan explained to Amy how she and Katherine could jack him off. A few minutes after he started this, Suzanne came over to the house and let herself in. Alan had to get out of the bathroom and greet her before she figured out what he and his sister were doing to her daughter.

Suzanne was very happy to see him as they met in the living room. Alan had stuffed his penis into his shorts only a minute earlier as he left the bathroom, but as soon as she saw him she noticed the cucumber shape begging to be freed. She unzipped him and began to stroke while she talked. She didn't even ask; she just saw him erect through his shorts and took what she thought was the necessary action.

Alan thought to himself, Now this is the life! Moving from one perfect ten woman on my dick to her mother! I'll bet Hugh Hefner doesn't even have it this good. Heck, these women put those Playboy bunnies to shame. Those are all blow-dried, air brushed, emotionless statues out to make a buck. These women are real in every way.

"Good morning, Sweetie," she said as she lightly blew on his penis tip. "I understand today is going to be a big day for you, isn't that so? A chance to get your daily average back up?"

"Yep. I guess that's so."

"Good. You can see I'm not going to waste any time. Has anyone blown you yet?"

"Nope." Alan thought to himself, Because I keep getting interrupted, not that I can complain.

"Then there's no time to lose. Here, a handjob isn't good enough. You deserve better than just another blowjob too. I'm ready for another deep throat. Would you like that?"

"Sure. But here? What if my mom comes back?"

"Oh. You're right. Quick - to your room." Suzanne had rather hoped to get caught in the common rooms by Susan, but let the point slide.

So Suzanne deep throated Alan, inadvertently finishing off a stimulation started by her daughter.

Across the hallway in the bathroom, Amy and Katherine had plenty of fun even though Alan couldn't be with them.

Alan, though, had the most fun. Amy and Katherine had gotten better at sexually pleasing him, but neither of them could yet compare to Suzanne and her considerable experience. And now that she knew how to deep throat, she was even more of a force to be reckoned with. Her first deep throat was just a partially successful experiment, and the second wasn't much of an improvement, but this one was much better.

She just kept coming forward and forward, until her nose brushed up against his pubic hair. Again, Alan was amazed that so much penis could fit in a mouth. He just couldn't get used to it. Her saliva covered his penis until she could slide back and forth on it like it was a greased pole.

At first, that was all she could handle - getting the penis in all the way. But before she was done, she had already begun to work on moving her tongue more actively. Suzanne considered her tongue her "secret weapon" in both blowjobs and kissing. It was remarkably agile and active, and had excellent reach. A few times Suzanne was able to snake out her tongue and lick Alan's balls even as her lips still slid around his penis.

Alan couldn't hold out long against such a skilled tongue and throat. She pulled his penis back toward her lips when he came so she could savor his cum in her mouth.

For Glory, a deep throating was a special occasion. But Suzanne seemed very nonchalant and eager to do it again. On the other hand, Glory was still far better at it than Suzanne was. Glory had her special lips, tongue, throat, and hands quadruple attack. It wasn't easy to do, which is maybe why Glory didn't do it often.

While they recovered, Suzanne talked about her plans for the day. "Sweetie, you and I have never gone to the beach together, just the two of us. I know you like to go to the beach every weekend. What if you went with me instead of your boring friends? I think I can do a couple things they can't do, if you know what I mean." Suzanne, again, was scheming to get him alone outside of the house so they could fuck.

"Hmm, interesting idea," Alan replied noncommittally. He was all in favor of the idea, but worried about the personal politics involved. If I disappear for the day with Suzanne, then Katherine and Susan won't take it too well. Even Amy might be disappointed. I left her in the lurch just a short while ago. Would it be better if maybe we all go together? But one can't exactly get a blowjob on a public beach anyways. But then again, Suzanne might think of something. If anyone could find a way to swing it, it would be her....

Suzanne impatiently leaned over Alan and cooed, "Sweetie? Please? If you go with me, I promise you won't regret it. I'll make you feel really, really good. I have a special surprise." She didn't want to just come out and say she'd allow him to go all the way and fuck her, as she wanted that to be a surprise.

"Special surprise? Better than a deep throat?"

"Mmm. Much better. Trust your Aunt Suzy on this one."

Alan mumbled, "What about the others?" He found it very hard to think. Suzanne and he had just finished dressing, more or less. But Suzanne's semi-transparent nightie did nothing to cover her charms, as she now hung above him. She ground her pussy down onto one of his knees which happened to be between her legs. Her mouth inched right up next to his, and he could feel her fragrant breath and smell her strawberry shampooed hair.

Suzanne delighted in slowly torturing him like this. She knew he was putty in her hands. But right as her lips nearly touched his, there was a knock on the door. Damn, Alan thought, What lousy timing. Interrupted seconds before a kiss, just like in the movies. Today has been the morning of interruptions.

"Who is it?" he asked as Suzanne pulled away.

"It's your mother. How are you doing?"

"Pretty good. Suzanne was just helping me out."

Through the door, Susan complained, "Suzanne, what did I say about getting permission from me first? Can I come in?"

Alan got up and opened the door. "We just finished up," he said to his frowning mother.

Suzanne sat covered in some blankets which had fallen to the floor, as she didn't really have any pants to wear when she came into the room and didn't want Susan to see just how scantily she'd dressed. "Sorry, Susan," she said, "but you know how we're hoping Alan will reach at least eight today to make up for these past days. So I thought we shouldn't waste any time."

"No problem. I agree. It has to be paced out through the day. But in the future, consult with me first, okay? Especially if I'm home. Now, since you two are done, I think... Oooh!" Susan stole a glance at her son's crotch and saw he was hard again. Suzanne crawling all over him no doubt helped him get that way.

Susan pointed at it. "Would you look at that, Suzanne? Isn't that just lovely? Didn't you say you just finished? How insatiable. Tiger, are you ready for some more assistance? Because if you are, I'd very much like to help out. It seems Suzanne can't take care of all your needs."

"Sure, Mom." He thought, Dang, this thing is really getting a work out this morning. Straight from Suzanne's mouth to Mom's! Fuckin' A. And I've got a really high target to reach today.

"Will that thing ever stay down?" Susan asked rhetorically. She cast a "please get lost" glance at Suzanne.

Suzanne ignored Susan's catty comment, and said, "I'll go see if the mail is here. Maybe that 'Cocksucking Monthly' magazine you've been waiting for so eagerly has finally arrived."

Alan was puzzled. He knew there was a recent profusion of specialty magazines like Cigar Aficionado, and seriously imagined a glossy "Cocksucking Monthly" sitting between "Good Housekeeping" and "Better Homes and Gardens" on a supermarket magazine rack.

Susan looked puzzled, too, so Suzanne clarified, "Joke, folks. That was a joke. Ah, well. I'll be off now."

Susan failed to watch Suzanne leave, because her eyes were now completely fixated on her son's crotch. Alan unzipped his shorts and Susan licked her lips as she moved into position. She hovered over Alan. She winked. "I think I need to subscribe to that magazine and buy all the back issues. Don't you?"

Alan thought to himself without irony, I have the feeling today is going to be a very good day.

CHAPTER 3

Alan made an effort to have a normal day. He read the newspaper for a while, and then surfed the Internet. Suzanne went home to take care of some errands of her own, still without a commitment on the beach idea from Alan, since Susan was underfoot and they didn't have another chance to talk.

Just before lunch, Susan strongly suggested that Alan take care of his "problem" yet again. Alan was feeling up to it, and Susan appointed Katherine to do the task since Katherine hadn't been given much penis lately. Again he retired back to his room, which had filled up with the smell of cum again, even with the window frequently open. There was so much sexual activity in there that the cum smell permeated every inch and pore of the room.

Alan whipped off his shorts and sat on the edge of his bed. Katherine wordlessly took off all her clothes and assumed the cocksucking position between his legs. He idly commented, "I don't even know why we bother with clothes lately."

She answered, "Clothes are fun. Taking them off for you and teasing helps pass the time until the next time you put your cock in one of my holes." She leaned forward to engulf his penis.

To her surprise, he held her back. "Just a sec. Do you want to do that, or a titfuck?"

"A titfuck? Oh goody! You'll let me do that in the house? But wait. I got a better idea. We can do both."

Alan poured some KY Jelly he had by his bedside into his sister's cleavage, and she demonstrated how she could flicker her tongue at his penis head while he pumped his penis between her tits.

He discovered that if he made very short strokes, she could keep her lips on at least part of his penis head at all times. He paused from time to time and she gobbled further down his penis, focusing on the sensitive spot beneath the head, until he was ready to stroke some more.

They went at it for a long time. Katherine was content to ride the peaks and valleys of his arousals, keeping him on edge and then giving him a chance to recuperate. She still talked excitedly about the previous night's spanking when her mouth wasn't full of penis. She clearly angled for a repeat performance very soon.

During one break, he asked her, "So which do you enjoy more: a straight cocksuck, or a cocksuck-titfuck combo?"

"Your fuck toy doesn't care," Katherine answered while referring to herself in the third-person. "She's happy just to have her brother's fat, cum-filled baseball bat do nasty things to her in any and every way. He always gives her lots of orgasms and a big load of sweet jism any way she takes it. And that's the truth."

"Sis, you don't need to talk in the third person. I'm still your brother, you know."

She giggled. "Please forgive me, Big Zucchini Brother. Maybe your sister, I mean, maybe I deserve a spanking for my disobedience."

"That's about the fifth time this morning you've suggested you deserve a spanking for something or another. If you don't stop it, I'm NOT going to spank you anytime soon. And you didn't disobey. In fact, you're not even supposed to obey my every whim. When did we decide that?"

"I decided that the first time you fucked me. It felt so good I literally saw stars. Your fuck toy lives to be fucked by you. Speaking of which, how can my mouth be so close to your penis without being fucked hard like the second pussy that it is? And look at my soft, sweet, firm tits: they've been tragically unfucked for a good three minutes now." She made big, sad puppy dog eyes and he relented as they both broke into laughter.

So Alan ended another break and resumed thrusting into her tits. Most of their conversations were in a similar vein to this one. Alan upbraided her for her degrading talk, but secretly he enjoyed it, and she knew that. She enjoyed it even more.

Alan eventually came. The tip of his penis was inches from her mouth, so most of it hit her there, but she turned her head this way and that so the flood of cum could hit her in the cheeks, nose, and chin as well. By the time Alan was done, he looked down at his sister and saw that he'd given her an impressive pearl necklace, gobs of his sperm dripping down the sides of her neck and chin like viscous milk.

When it was over, he still felt weirded out by his sister's attitude. So he said, "Sis, now that we're not in a sexual mood, things go back to normal, right? We're just the same old brother and sister, right?"

"Yeah. Sure. It's not like I'm gonna do your dishes for you or anything. We're still cool."

"Good. Because I'm just a little freaked. Let's do something totally nonsexual for a change. Just like the old days." He found it a bit difficult to discuss anything nonsexual when she rubbed his cum into her skin all over her face, but he persevered.

"Okay. What?" she asked after she licked her palm clean of his sperm, her eyes doe-like and pretty as she stared up at him quizzically.

"Oh, I don't know. How about we play some video games? One on one shoot 'em up? I know you like that." He unstraddled her and stood up, his penis still at half-mast as it hung between his legs. He offered his sister his hand to help her sit up.

Katherine glanced at her brother's penis and noticed that there was a large drop of unspent cum that dangled lazily from the tip. She scooped it up with a finger and said, normal as ever, "Cool."

So they played a video game together in the living room. Alan was actually greatly relieved to have this revival of old habits. He was even relieved to see his sister completely clothed, just as Susan was clothed as she worked in the nearby kitchen.

Katherine saw that he needed a mental return to normality, so she purposely avoided any flirtation or exposure. Indeed, he was happy to see they could still relate just as they did before. Soon they were laughing and having a great time. The only lingering evidence of sexuality was the smell of cum and a slightly different sheen to her face from her facial.

She thought to herself, Looks like Alan needs some time to adjust to this whole fuck toy idea. I'll just have to take it slow for a while and tone down the language until he realizes his- or my- rightful role. I guess no spanking for me today. Shucks. That's okay, though. The important thing is what happens in the long term.

They finally had to call it quits when Susan announced that lunch was ready.

CHAPTER 4

After lunch Alan napped again. When he woke up around two o'clock, he wanted to do some swimming. Although it was November, it was still a hot, sunny day in Southern California. He went to find Suzanne so he could take her up on the beach trip idea, but when he came downstairs, he found Katherine, Susan, and Suzanne out back by the pool where they sat in lawn chairs. He went out there to join them.

When Suzanne saw him, she commented, "Since I didn't get a promise from you about the beach, Susan insisted on this instead. Seems she didn't want to be left out." Alan noted that Amy wasn't around, as was the case when Brenda came over on Wednesday. Alan correctly guessed that Suzanne had sent Amy away so the rest of them could engage in more sexual shenanigans. Suzanne was blissfully unaware of Amy's sexual activity earlier in the morning. Amy was a blind spot for Suzanne's otherwise very observant mind.

At first, all of them swam in the pool. But the swimming together started to increase everyone's arousal. Suzanne's bikini top was so skimpy that she had no problem repeatedly making it "accidentally" come off whenever Alan was around. Susan, by contrast, wore her most conservative bathing suit. She shot Suzanne some dirty looks, but less and less as time went on. In fact, the only reason Susan minded Suzanne's displays was because she worried Suzanne would steal all of Alan's attention.

After swimming, Katherine, Susan, Suzanne, and Alan returned to four nearby lawn chairs.

Suzanne and Katherine would have gone topless or altogether naked, but they still took their cues on what was acceptable from Susan. Alan's mother was an enthusiastic cocksucker in private, but around others she was still shy to even dress scantily.

Their lawn chairs were all only a few feet from the edge of the pool. Suzanne and Susan lay in chairs next to each other, and Katherine and Alan's chairs made another pair right behind them, but facing in the opposite direction. They had punch to drink, rock music that blared in the background, and trashy novels to read. Suzanne had secretly spiked the punch with alcohol, to help further things along. Alan thought it strange that both Susan and Suzanne wore high-heeled shoes even while sunbathing, but didn't say anything about it.

Spirits were definitely reviving. The lawn chairs were all in the shade of some trees, but the afternoon wore on and the intensity of the sun lessened. So after a while, Suzanne pulled her chair out into the sun, and everyone else followed suit. Suzanne, with her pale skin, normally avoided the sun like the plague, but she knew that moving into the sun would be followed by a need for more suntan lotion. As she'd expected, all eyes turned to Alan.

Suzanne was also the first to speak up. As she held up a bottle of lotion, she said, "Sweetie, would you be a dear and cover me up?"

She undid her bikini top and let it fall to the ground. That act set off some kind of secret nuclear arms race of nudity. Susan quickly excused herself. Upset that she wore such reserved garments, she quickly reappeared in her most revealing one. But by the time she got back Katherine had joined Suzanne in being topless. Susan wasn't willing to follow suit, if it wasn't just Alan watching.

She couldn't exactly order Suzanne around, since they weren't related. But she could order her own daughter, so she forced Katherine to put her bikini top back on. However, despite all these efforts, she knew that she was still upstaged by Suzanne.

Surprisingly, even Alan flashed a lot of skin. Suzanne had recently given him one of those European styled bathing suits that he said he'd detested only a month or so ago. The short red suit that he wore for the first time was almost like a male bikini bottom. He wondered what would happen if (or, more accurately, when) he got a hard-on, because there was seemingly nowhere for an extended and engorged penis to go.

Alan began to work on Suzanne first once the bikini situation resolved itself. She would have been his first choice anyway, because he wanted to get the greatest potential for mischief out of the way early before he got too excited. He remembered how, when he was asked to apply lotion to the three of them last time, he had to flee for fear of losing all control to not just start fucking each and every hole. He was determined to control himself better today, so he could take things a little bit further.

He wordlessly moved over to the pale beauty and brazenly straddled himself right on top of her. His hard penis was in severe danger of popping out of his tiny suit, so he pushed it along the thin fabric that connected the front of his suit to the back. It kept it covered, but just barely.

Suzanne's toned and firm body felt wonderful underneath his hands. All the workouts Suzanne and Susan did together continued to pay off. Their bodies were the essence of perfection. Alan started on Suzanne's back, and worked his way down to her feet. Along the way, he devoted great attention to her ass. He would have slipped his hands under her bikini bottom, but there really was no bikini to speak of in the first place - just a single string that ran down her crack. So he had free reign over her butt. It was in direct sight of his mother's watchful eyes, hidden behind her sunglasses, but she didn't say anything to stop them.

Almost as soon as he began, his penis popped out of his far-too-revealing bathing suit, despite his precautions. He modestly popped it back in, but each time he shifted his weight or made any sudden movement, it would pop out again. His mother didn't even chide him on this, as the application of lotion passed in nearly complete silence. The anticipation was killing her - she figured anything Alan did to Suzanne would soon be done to her. She licked her lips and her pussy quivered in anticipation of having his penis rub across her naked skin.

It took a good fifteen minutes for him just to do Suzanne's backside. He figured it would take him a good hour and a half to finish all three of them at the absurdly lazy pace he took. They all seemed to make similar mental calculations. So Susan and Katherine put their own lotions on themselves while he did Suzanne, to prevent them from actually getting burned. Of course that pretty much negated any reason for Alan to put lotion on the other two, but no one wanted to point that out. Only Alan's skin remained unprotected from the very penetrating sun.

Suzanne and Katherine had arranged a bit of a trick before they went outside. They'd worked out a way to talk extensively about Alan's penis to get Susan more worked up. Suzanne started it by saying, "My, my. Looks like Alan is hard as usual. Katherine, didn't you just take care of him a short time ago?"

"I sure did, and it was fantastic. As usual. I don't think I could ever get bored of putting my brother's thick, wide, fuck monster deep in my..."

"Angel!" Susan chided. "Please! Let's have some decorum. Let's not forget the boundaries. There's no need to talk about that kind of thing."

"But, Mom, there is. I'm concerned." Susan sat up in worry. Katherine continued, "I'm concerned about the state of Alan's penis. As you know, I've given him handjobs and blowjobs before. A good deal before we were even caught, as you know now. But today his penis seemed even bigger than before. Thicker. Longer. Tastier. And the endurance! Jesus! It's unbelievable. It wears my mouth out. His penis is so huge, and growing, I'm wondering if it'll reach a point where he simply won't be able to fuck a woman with his oversized tool. I imagine it could barely fit into a vagina now, and if it did, it would fill it up and push against the sides and ram against the back so much that it would practically seem like giving birth. Imagine that feeling of fullness. It must be ten inches long now, at least."

Of course Alan's penis hadn't actually grown in any way, though his endurance was continually improving. But this is what Suzanne told Katherine to say to get Susan worked up. And it worked only too well. Susan complained, "Angel, what you're saying is impossible. Nobody's penis just up and grows a couple of inches overnight. Really! You're too much. In any case, we're outdoors. Anyone could hear us. Please don't talk like that about your brother..."

"Mom, it's so true! Don't you agree, Suzanne?"

Susan saw Suzanne nod. Suzanne then said authoritatively, "Susan, sometimes this can happen. Think about your private parts. Aren't your tits, ass, and pussy always kind of tingly and ready for action these days? I know mine are. Aren't you always thinking about how good it would feel to have Alan penetrate you in all kinds of exciting ways? Well, when a man is similarly and constantly stimulated twenty-four hours a day, his penis tends to just get bigger and bigger, in the same way that your nipples are almost always hard and your pussy lips are almost always engorged, wet, and ready to be fucked hard."

"Wow. Is that really true? I didn't know." Susan considered, I AM always tingly and ready for action. Sometimes I feel like I'm just a package of tits, ass, and pussy put together, because all three spots are on fire all day long and they do most of the thinking for me. At least when I'm in a horny fog, which seems to be most of the time.

Katherine enthused, "Measure it yourself, Mom. Would you like me to get a ruler, so you could take his giant organ in your hand and hold it against the ruler? Do you want to take it in both hands and rub his fuck stick thoroughly so it gets nice and long, and then you can measure it at its maximum size?"

"Yes! ... I mean, no. Maybe. ... No. I shouldn't. That's improper outside the house like this." Susan fully writhed about in her lawn chair now in absolute and direct evidence to the contrary of what she'd just said. She desperately wanted the conversation to change before she was forced to blatantly rub her clit and get off. "And Angel! Don't call it a fuck stick! Oh, my!" she gasped with realization. "I just said...! Please watch your language. In any case, I'm sorry, but it just doesn't get that long. And how could it possibly get even more tasty? That's pure silliness."

"Maybe it's your technique, Mom. Maybe Suzanne and I know how to make it get longer and harder than you do." The daughter had gotten quite worked up with her own talk and hefted her bikini-clad tits with both hands.

Susan didn't seem to notice and replied hotly, "That's absurd! Why, I'll tell you, it gets PLENTY long, all slicked up and sliding around in my soft hands. And when I put it in my mouth..." She launched into a spirited defense of her skills. The conversation went into detailed discussions of handjob and blowjob technique, and a heated debate as to who was the best cocksucker.

This was just as Suzanne planned. The idea was to keep the conversation sexual at all times, to continually raise the sexual tension and leave the "boundaries" behind. Even though Alan was there, he was almost completely ignored. No one solicited his opinion on such questions as to who could blow him the best, as they all knew he would give a diplomatic reply to try and keep them all happy. Soon Susan and Katherine writhed around and rubbed their privates against hard corners of their lawn chairs at every opportunity, their brazenness of their behavior limited only by the fear of being seen by the other females.

Meanwhile, Suzanne had more pleasant rubbing to contend with. Alan continued to apply lotion to her fabulous body. He spent even more time on her front side than he did her back. Starting from her legs, he saved the best for last: her giant jugs. They were completely unencumbered by any fabric, yet still held out so stiffly that it seemed as if they must be fake. Alan spent more time getting to know them better than ever before. He pinched or brushed over the nipples at every semi-plausible opportunity.

By this time the conversation had died down. Susan and Katherine both sat up in their chairs as they panted and watched Alan's squeezing hands very intently. But, in an effort to maintain some level of decorum, Susan finally said, "Okay, Alan, I think you've gotten Suzanne's breasts more than thoroughly covered with lotion already!"

Suzanne replied with a lazy, contented smile, "I don't know - my skin is so pale there. It pays to be extra careful." Of course, her skin was equally pale everywhere. She added teasingly, "I think someone is just jealously waiting for her turn."

"It'll be sunset before the poor boy finishes, at this rate," Susan grumbled as she dodged the comment. By this time, she wanted Alan so bad that she could literally taste his cum in her mouth. She clenched her legs together fiercely to prevent herself from touching down below. Most importantly, from Suzanne's point of view, was that Susan was far too hot and bothered to enforce her boundaries.

"Poor Alan," Suzanne pouted. "Sweetie, you must be getting all worked up, and there's no relief in sight!" She tugged at his bathing suit and caused his thick pole to pop out yet again. It seemed that each time it came out it took him longer and longer to put it back in.

"Susan," she went on, "Katherine was the last one to help Alan out today, but it looks like he needs some more help. Can I do the honors?" She began to play her fingernails over Alan's still-exposed penis. She held the nails just far enough away from the skin so that it was almost impossible to tell if contact was actually being made, but it created an exciting tingling for Alan.

"What? Now? Here?" Susan asked incredulously. Susan had assumed that Alan would get hard from seeing them all by the pool, but figured he would be taken inside to be pleasured. To do that in front of others had been done the night before with Brenda there, but Susan in her erotic mood forgot all about that.

"Look how bad he needs it right now, Susan." She began to stroke his penis openly. "Isn't it better if he can calm down for when he does you and Katherine? Do you want him to suffer in complete torture for the next hour? Is that how we repay him for helping us out?"

"Well, no, that would be mean. ... But you can't just do it here, in full view of everyone! In front of the neighbors? Can you?!?"

"Who is 'everyone'?" Suzanne replied. "Just you. No neighbors can see in here. Not even Katherine can see from where she's sitting." Katherine lay less than ten feet away and could see easily if she only turned around, but she quickly closed her eyes and pretended to be asleep in hopes that would help weaken her mother's resistance to Suzanne's schemes. Suzanne added, "And if you don't want to watch, just close your eyes."

Suzanne had softened Susan up so thoroughly with the long cocksucking technique conversation that Susan put up nearly no resistance to this first-allowed and public penis stimulation. All Susan said was, "I think I will, then," and she did close her eyes. She leaned back deeper into her lawn chair.

But as she lay still on her back, with her bountiful and nearly naked tits thrust into the air, she realized that behind her sunglasses, no one would know for sure if her eyes were open or closed. Her resistance to keep her eyes closed quickly broke down, but she was careful to only look over at Suzanne out of the corner of her eyes so her friend wouldn't suspect. However, she only fooled herself.

At this point, Alan had been straddled over Suzanne's stomach, in the optimum position to play with her boobs. Suzanne motioned him with her hand to scoot backwards, and he kept on scooting until he reached her feet at the edge of the reclining chair. That enabled Suzanne to bend forward at the waist and place her head in Alan's crotch. When she pulled the fabric of Alan's nearly useless bathing suit away from his balls, she began to suck his meaty organ. One hand grasped his balls and the other fondled his ass, while her mouth did all the rest.

This is wrong, thought Susan as she watched. Why did I agree to this? They should have just gone inside. It's just that I feel so sorry for his 'blue balls' condition... But I really shouldn't be watching this, right? There's no real reason to watch ... except maybe to see how Suzanne does it. ... She's good - better than me. I could learn some tips. Maybe they do get it more excited than I do? ... If only Alan had fucked me at the Halloween party, I could have satiated my horny urges, and I wouldn't be like this. ... No, can't think that way. I'm going to be the best cocksucker there is, so I have to learn everything she's doing, and do it better. I'll show them!

Oh my God! Did she just stick her finger in his anus? She did! She put it up his butt hole right here outside in the back yard! I can even hear that damn slurping sound while he's ramming into her greedy mouth. The neighbors could be watching. I can't believe it! And now she's moving her finger in and out of it like a mini-buttfuck. Should I be allowing this in the outdoors where any neighbor might see? This is too much; the neighbors would think we're anal perverts. I have to say something! But Susan didn't speak up to stop it, and Suzanne continued until he climaxed.

Suzanne was a very good cocksucker indeed, even when she wasn't deep throating him. Amongst other things, she was excellent at swallowing all of Alan's big loads. She began to drink in everything his pumping penis shot out, but half-way through, she pretended that it was too much to take, and slowly pulled her head back until his penis squirted on her face instead, and cum drooled out of her mouth. She figured the sight of all the cum would help excite Susan even further. Since she couldn't fuck Alan today, she wanted to work on her other scheme: further corrupting Susan.

"Oh, it was just too much!" Suzanne bemoaned to Susan as she lifted up her head from Alan's lap. Susan had nearly cum just from watching, but she didn't quite get there, and she was even more flustered than before. "Look how badly he needed to go - he literally filled my mouth with cum! Alan you must have been in pain, backed up with too much semen!" Suzanne turned her body towards Susan to show just how much he had shot, even after she had drank much of it in. She showed off the cum as it dripped down her nose and chin and fell onto her tits, as if she was exasperatedly showing how someone had playfully splashed a glass of heavy cream over her.

Susan had a nearly overwhelming urge to lick all of Alan's cum from Suzanne's face and chest. She practically rose up out of her chair, but managed to restrain herself. She thought, So much yummy seed. Mmmm. Yummy, yummy, yummy! Mommy needs it. Suzanne, don't just sit there and let it all fall to the ground! Don't waste a drop! Mommy knows what to do with it, even if you don't! She involuntarily and unconsciously licked all around her mouth with her tongue, as if the cum were on her face instead. Her pussy literally twitched with the desire to be filled and pummeled, but still she couldn't cum.

Katherine experienced similarly pleasing frustrations. She also wanted a face full of cum. And with all of her recent lesbian experiences, she was turned on by Suzanne, too. It would have been a double pleasure for her to lick Suzanne's face clean of her brother's cum.

Alan saw his mother greedily lick herself and thought, Jesus! My mom is acting like a total cum slut. Is she? If she is, why does she always deny her true feelings and never let me fuck her?

Suzanne went on, "But don't worry about me, Susan. I'll get myself cleaned up. Why don't you put some lotion on my cute little Sweetie or he'll get burned for sure. Then, since you're nearly as pale as me, he can do you next."

CHAPTER 5

Susan was shaken out of her reverie. She saw how Alan was still not covered in lotion and in fact was getting slowly burnt. She called for Alan. "Come here, Tiger." Susan sat up in her lawn chair and arched her arms back, which caused her bikini to ride up and momentarily expose her nipples. Alan's eyes ogled. She pulled her top back down.

"Thanks for that, Aunt Suzy," was all Alan said to Suzanne as he got off her, as if she just did some inconsequential thing like hand him a glass of milk.

Susan smiled wide, as it fully registered that Alan was headed her way and what he'd soon do to her. Her face was wholesome; she just looked like a normal, happy, suburban, soccer mom. Her innocent look contrasted with the sex slut she felt to be on the inside at the moment.

Alan straddled his mother on her stomach just above her crotch, but he put his back to her face so she could apply the lotion to his backside.

She tried to act restrained, and she moved slowly so she could calm down a little bit. "Now, Tiger, we've done some things lately that perhaps weren't so wise. I'm thinking of a certain chocolate frosting shower recently, for instance. If you have any urges, that's good and very healthy, but let me know so I can take you inside and help you out there so we aren't a spectacle for our neighbors." Alan nodded.

From her reclined position, Susan covered him thoroughly but quickly. Mostly she rushed because she wanted to get to where he was putting lotion on her instead. He turned around and straddled her the other way, and she ran her hands lovingly all over his face, arms, and chest. The prescription sunglasses she wore weren't really dark enough to hide her eyes, but they gave her an emboldening sense of anonymity anyway. She moved her hands down to the edge of his suit which hung so low that some pubic hair stuck out the top. She looked at his penis through his suit. She could see virtually every detail, every vein, as if he had no suit at all. But she stopped there.

To get at his legs would mean having to get up from her reclined position, and she felt really lazy just then. Is there something in that punch? she momentarily wondered. I feel so relaxed! I have this overwhelming desire to spread my legs and let Alan get really comfortable with my body. But that would be wrong, wouldn't it? She took the easy path. "Tiger, why don't you do me for a while, and then I'll get your legs later."

Alan simply remained where he sat, on top of her stomach, and began to cover her chest, face, and arms with the lotion. Her boobs came last, before he had to move further down her body. Unlike Suzanne, Susan still wore a tiny bikini top. Just two little triangles of fabric were all that protected her nakedness. So he avoided those two spots, which meant he couldn't play with her nipples at all, even as they stuck out temptingly like hard erasers.

Susan's pussy was on fire. Her nipples screamed for attention. Her mouth longed to be filled with a penis or tongue. The only reason she still kept her bikini top on was because she was worried that if he touched her nipples, soon she'd beg him to suck and milk them. That wouldn't look good in front of Suzanne, who spied everything through her sunglasses. In fact, the real reason she generally let him fondle her butt more than her tits was because her nipples were extremely sensitive, and when he touched them it absolutely drove her wild. She reveled in a fantasy of him sucking her nipples like a full-grown baby and that thought alone almost pushed her over the edge.

Alan didn't know any of that, except that he could sense her poorly hidden excitement. But he gave the rest of Susan's boobs a LOT of attention. His fingers plunged down into the tight crevice of her cleavage again and again. He put lotion on both hands and pushed her boobs together from the outside. Then he pulled them away from each other and then, scant seconds later, pushed them inward. He pushed and pulled and mauled them every which way.

He thought, I cannot believe my mom has such perfect boobs. I must have been blind all these years to not think of her more sexually. It's like someone took an ordinary pair of tits and pumped them up with a bicycle pump. They look like balloons. And they feel so soft and pillowy! So nice!

He must have spent at least ten minutes on just her tits before she finally, quietly said: "I think that's enough, Tiger." She had him stop because her pussy was very wet and she didn't want him to notice as it got even more obviously soaked. Again she was on the verge of a powerful orgasm and feared thrashing around with Alan right on top of her. Somehow she restrained herself. In yet another remarkable display of restraint, Alan had avoided her still-covered nipples all that time.

Alan got up and rotated around, so he could begin to work on her legs. But he'd long given up on trying to keep his penis inside his far-too-tiny bathing suit. As he stood over her momentarily, Susan looked up and gasped as she saw his penis poking far out of his tiny suit. About half of it was out of the suit and lay against his stomach. Pre-cum dripped out of its tip like water from a recently turned off faucet, the liquid thick and translucent as it pooled near his belly button like clear honey.

Holy mother of God! Susan thought. That looks so good! Maybe they're right and it IS ten inches instead of the eight I've come to know and love. There's only one way to find out for sure, and that's to test its size with my mouth. I would give a kingdom just to suck it all day long. No longer am I just a homemaker. I've started a new career: cocksucker extraordinaire for my darling son. That's what I do. I live to suck his cock. But I can't right now, with Katherine and Suzanne expecting me to be the restrained one. They're watching me. I'd feel so self-conscious, especially to have Suzanne judge my every move. I'm not going to sink to her level and just do it anywhere, with anyone watching, like some kind of common whore! I'll just wait until he says he wants me to go inside and take care of it. ... But it looks soooo good! So long and thick and tasty. Maybe if I just touch it, like I'm trying to help him put it back in his suit... No, that's not gonna work. It'll just end up in my mouth right here in front of everybody.

By this time, Alan had straddled his mother again and now faced in the other direction. She could no longer see his penis and breathed a huge sigh of relief. What a close call! I almost came AGAIN! What torture. I would have lost it if he had stood there much longer.

But just as she thought she was out of the woods, she felt his penis lay down onto her lower abdomen. It pointed towards her pussy from mere inches away. Good Lord! God, if incest is so wrong, give me the strength to resist it. Give me the strength to tell him to put his thing back in his suit before I embarrass myself in front of Suzanne and my own daughter. But she said nothing.

Alan began to work on her legs. He started at her feet and worked his way up to her crotch. He kneaded her flesh and gave her as much of a massage as an oil rub. Her legs were tightly shut together. As he got up past the knees, he said, "Open your legs a bit more, Mom."

Susan replied sheepishly, "Mommy doesn't want to."

"If you don't, your thighs'll burn later." He began to gently pry her legs apart with his oily hands.

Finally she yielded and relaxed the muscles in her well-toned legs. "Okay, but don't get too close to you-know-what..." Behind his back, her face was beet red with embarrassment even though she thrilled at his touch and slightly insistent manner.

Alan took a good, close look at his mother's crotch. Her tiny, little, yellow bikini bottom barely made a pretense of covering her pussy and he could see a bit of pubic hair stick out the sides. He also saw that his mother was really, really soaking wet. The miniscule triangle of fabric was soaked through and juice dribbled down her thighs and onto the lawn chair. This was one reason for her shame, but Alan said nothing to embarrass her further.

Alan's hands worked their way up her thighs and he saw her juices continue to flow. The closer his hands got to her pussy, the more she leaked. There was a series of rivulets all over her upper thighs. Finally, his two hands reached up to a couple of inches from her pussy and the gooey wetness around it. He could sense her hips begin to slightly gyrate and the heat from her moist mound practically left him intoxicated with lust. Her legs also began to spread on their own accord, as though her lower body was readying itself to be penetrated.

Susan looked over at Suzanne, who blatantly stared and sat up in her chair to get a better view of Alan and what his hands did. Suddenly, Susan felt a great sense of shame and said, "Tiger, I think that's enough. I'll take care of the rest ... in that area."

She felt a tremendous sense of relief that the exquisite torture was finally over and that she'd survived all of his temptations. But then Alan said, "Okay, then, turn over."

Oh no! I've forgotten about the backside! She exclaimed to herself, Oh God, dear God, Alan, no! It's too much! If he touches me any more, I'm going to cum for sure. I'm going to cum buckets. Everyone will see! But at this point the idea of cumming profusely sounded very appealing, audience or not. She obediently, almost joyfully, flipped onto her stomach.

Alan said, "Mom, if you want me to do your ass properly, you'd better take off your bathing suit bottom." The bikini covered so little skin that it was fairly absurd to ask her to take it off, but Alan sensed Susan wouldn't object.

She replied, "Tiger, do you want to see your mother all naked in front of friends and family?" It was a rhetorical question and she knew it. "Okay, if you must. I guess you've seen me naked so much already; everyone here has seen me so naked. I'm like a totally naked..." She wanted to shout "slut!" but she knew Alan wouldn't approve.

Instead of finishing her sentence, she turned to a new thought. "Do my ass. Do it properly!" Then she realized how that sounded like she wanted him to butt-fuck her, especially as she said it so enthusiastically. So she added. "You know what I mean. The cream. I mean, the lotion. Put the lotion on."

Alan began to do her back languidly. It was even more like a massage as time went on. She felt completely relaxed when his hands dug into the skin around the shoulders in a pleasant and penetrating massage. Even though her pussy had calmed down a bit, she continually leaked and rode a wave of erotic bliss that seemingly never stopped but just varied in intensity.

By this point, with her eyes no longer able to see what he did, Alan not only kept his penis on her skin, but he deliberately rubbed it against her. It rubbed deliciously along the silky skin of her ass as he swayed his whole body back and forth to vigorously rub her back. She obviously knew what it was that poked and stroked her, but she didn't speak a word and instead enjoyed every blissful, secret moment of it.

Whenever he had a chance, such as needing to get more suntan lotion on his hands, he'd put a hand on his penis and rub it, which also pushed it further into her flesh. Soon it took him minutes at a time to get more lotion and the ostensible application of lotion slowed down even more. He tended to leave a trail of pre-cum wherever he placed his penis now, like a water gun that leaked a thin, continuous stream of viscous fluid right onto his mother's ass.

Alan moved his hands down to her butt and massaged that briefly as well. His dick rubbed back and forth on top of her thighs.

Susan suddenly realized how close they were to fucking. "Tiger, be careful!" she said between very heavy breaths. "I trust you. I trust you won't stick your thing right in my..., right in my..." she was too worked up to finish the sentence. Finally, she rushed out, "That would be so improper!"

Alan decided to obey her wish, especially since, if he changed positions now, he'd have an excuse to go back later and do her naked ass more thoroughly.

He was quite a bit more sexually experienced than even a week earlier, and he could sense how close to climax she was. He enjoyed keeping her right on the edge without letting her go completely over. Just when she thought she would finally lose it and explode into an overwhelming torrent of sexual delight, Alan would pull back a bit, or even stop altogether. She was like putty in his hands and almost completely ceased to think; she just gave in to whatever he wanted to do and let her feelings wash over her.

All the time he continued to apply the lotion. After a while he pivoted around and moved to her legs. With each stroke of her lower legs, his erect penis also stroked along her skin, right on her ass cheeks, and pointed directly at the barely-hidden cleft of her pussy lips. As a result, he spent more time on her lower legs than he otherwise would have. Soon, he only used one hand at a time to rub her legs. He used the other to move his penis around and simultaneously stroke it, instead of trying to guide it with his hips.

She thought to herself, Mmmm, that feels so good. His penis is so hot. It feels like it's branding itself into my skin. What a great idea! Imagine if I had a brand on my ass that showed I was his property? His slave! A big "A" for Alan. His fuck-cow sex-slave. I'm a big, fat fuck-cow, but instead of having to be milked every day, I need to be FUCKED! Fucked AND milked, actually. Oh yes... Tiger, fuck me...

Shut up, Susan! Stop thinking these demeaning thoughts. Even though it feels so good. I'm his cocksucker now. That's what I am, and that's as far as it goes. I have to accept that idea completely. Every day from now on, I'm gonna suck him dry. I don't care where he goes; he's never going to get rid of me. Every day. He's going to fuck my mouth. He's going to fuck my tits. He's going to fuck my ass - even that. Especially that! He's going to fuck me and use me and abuse me! I'll take his seed into every orifice I have, except one, and BEG for more!

Stop it! There you go again. Those things are not allowed, either. Just think about the cocksucking. Imagine the taste of his penis in your mouth. Mmmm.... Mommy loves it... Tiger, your mother needs your cock right now. Put it in my mouth. No, don't just put it in. Shove it in. SLAM it in! God damn, fuck my mouth! Slap your balls against my chin and yank my hair with your hands as you force yourself into me! Fuck it! Fuck any hole! Take me anywhere, in any way! Fuck your mooooommmmmy!!!

Susan, to her great relief, finally had an orgasm, a thunderous and fully engrossing orgasm that started from deep within her belly and fluttered straight out to her toes, like a shockwave of pleasure. Juice poured out of her pussy like Coke exploding from a shaken can. She was so overwhelmed that she literally saw stars. Her heavy breaths turned into brief yelps, which turned into screams. Her eyes were closed the whole time. She had no idea how Suzanne, Katherine, or Alan reacted, and she didn't really want to know. She was completely lost in the moment.

But as she came to, a realization overwhelmed her. Tiger is still here. He's on top of me. He's still not done. There's so many hours left in the day. What'll he do to me next?

CHAPTER 6

When Susan finally came to, she expected a wave of post-coital guilt to hit her, but that didn't happen. Yes, she was ashamed, but that didn't stop her before. She tried to pretend that Suzanne and Katherine weren't there.

Alan's penis still rested on her skin and she decided that, if she focused on that sensation, she could drive the conflicted thoughts out of her brain.

As she luxuriated in the sensation of his penis as it rested on her thigh, her horny feelings flooded back at nearly the same intensity as before. For some reason, she found herself thinking in a British accent, Thank you sir, may I have another? Then she giggled inside and repeated it again. She thought it was from some movie, but couldn't recall which (it was "Oliver!"). Thank you sir, may I have another? It was even funnier the second time and she idly wondered if she hadn't lost her mind.

Alan wasn't idle and kept working the lotion farther down her legs. When he reached all the way down for her opposite foot, his penis moved onto her ass. He surreptitiously used a hand to wedge his penis right into the crack of her ass, and it stayed there, its tip like a homing beacon that sought out her deepest, darkest depths.

Susan clenched and unclenched her butt muscles in an attempt to drive it away, or at least that was what she told herself. But it only served to drive it deeper into her crack. She finally gave up the battle and it lay wedged lengthwise across her sphincter. She could easily have moved it away by reaching around with a hand or saying something, but she didn't want it to move. Indeed, she wanted it to delve deeper into the crack and, with any luck, penetrate her puckered hole until he filled her completely.

As Alan's hands worked their way up her thighs from the back, he didn't have to ask her to spread her legs again; they were already spread widely and invitingly as he drew closer. When his fingers finally came to the back view of her pussy, she began to shudder in quiet, tiny orgasms.

She bit down on her lips and prayed that he wouldn't notice her passion, but her body gave her away. Her pussy lips practically trembled in delightful anticipation of being penetrated, pummeled and thoroughly fucked by her son in the outdoors and in front of both her best friend and daughter.

She fully expected that to happen. In her mind, she cried out, Fuck your slutty, cocksucking mom! She wants it! She needs it! Yes - right there. Closer! Put your hands on it. Put your fingers on my pussy - put them IN my pussy! No! Not your hands- YOUR COCK! I want you to push your hard, throbbing monster into your mother's pussy! Punish me with that pole!

Katherine and Suzanne had similar thoughts, just from watching. No one looked at them, so they were free to indulge in open gawking at Alan's hands on his mother's butt. Suzanne had been recently satisfied, so she wasn't too wound up. Weighing the pleasure of masturbating herself versus the potential displeasure that might give Susan, she decided to just rest herself for a while.

But Katherine was agonized. She was still forced to wear a bikini top, though it was so tiny and tied on so loosely that it fell off of her nipples more often than not. She nonetheless resented the restrictions placed on her even as her mother fully enjoyed herself. She especially resented not being able to finger fuck herself to satisfaction.

She thought as she stared, Shit. When is he going to get to me? Is he ever going to get to me? Once he gets started with Mom, he doesn't stop. She's going to drain his balls and leave me nothing. Dump a load on MY face, Brother! Dump it in MY ass. Anywhere. Just come over here with your healthy, monster fuck-pole. Your number-one sex toy needs it! Have mercy on your sister. I'm going to explode with frustration over here! Arrggh!

Susan was completely oblivious to her daughter's mood and, in fact, knew of nothing in the universe except the penis trapped in her ass crack. She thrust her hips up and down and clenched and unclenched her butt muscles. It was practically as if Alan was fucking her, or she was fucking him, just from his penis being squeezed by her butt.

But, surprisingly, he kept his cool. He worked his hands on her ass almost as though he was on auto pilot, his mind lost in an erotic fog. He didn't think in the normal sense; instead, his mind was fully devoted to absorbing all the sensory information that flooded into his head. Not only did he concentrate on the squeezing around his penis, but also the sliding of his hands over her oily skin. And even though they were outside, the smell of sex was overwhelming. He sniffed it in as he would a fine wine.

By this point, he didn't even bother with the pretense to actually put more lotion on his hands. He just kept rubbing her skin methodically. There was enough suntan lotion in the area to make her butt deliciously slippery and fragrantly oily, and he imagined that all the slickness was caused by numerous cum loads and sweat from his dick, not the lotion. So much pre-cum drooled out that it seemed as if he'd dumped at least one load on her already, so that helped his fantasy.

Without warning, Susan was overcome by another tremendous orgasm. Her contractions inadvertently and delightfully squeezed his penis even more. Her body stiffened and her mouth opened wide as if to cry out. She desperately wanted to yell "Fuck Me!" but no sound actually escaped her lips except for very heavy panting.

As she came down from her orgasmic high, a wave of shame passed over her, finally. She realized, I can't bear to look in Suzanne's direction, but she would have to be completely blind not to notice that. I'm supposed to be helping Alan out, but that kind of orgasm is not supposed to happen! This is all about pleasing HIS penis for HIS medical needs, and I shouldn't be enjoying myself so much. It's ruining my judgment. I have to calm down and get Alan off of me before I do something I'll really regret! Otherwise, this might go on all day.

She replayed her thought: Get Alan off. Heh-heh. That's right. I have to get Alan off! Tiger, fill your mother's mouth with your cum until it's all full and spills out onto her big tits. My tits... They need to be yanked at, just like the teats of a cow. I'm your sex cow. Moooo! Moooo! She giggled out loud. Give me another orgasm like that last one, Son, and I'll be your sex cow forever.

But Alan kept going on his mother. Susan tried her best to keep her butt still, since that was the focus of Alan's attention. And she was pretty successful at that, but her body was full of energy that needed some release, so the rest of her body writhed in ecstasy. Her hands and legs silently flailed in the air, as if she tried to swim away from her lawn chair. She simultaneously wanted Alan to stop and not stop. Even though she'd just climaxed, within minutes she worked towards an even bigger one. Do me all day, Tiger. Do it to me again! Keep me naked, happy, and well-fucked. I'm your mommy, Tiger. Do fun and nasty things to your mommy!

Knowing that Suzanne's eyes were upon her, Susan tried her best to make it look like she was having an ordinary lotion application and massage, but she knew she had failed miserably. The only thing she was really successful at was to keep her mouth shut. It was about all she could do not to moan, because she knew that if she gave in to that, before long she would scream or say really weird things. She had a nearly irresistible desire to cry out, "Moooo! Moooo! Sex cow! Mommy is your sex cow! Moooo!"

After a few minutes, she couldn't even control her butt and she began to flex and unflex her butt muscles again, which again served as a sort of masturbation or fucking for Alan's penis lodged along her ass crack. But, eventually, Alan had to take his penis out of his mother's crack, because he wanted to replace it with his lotion-covered fingers and he didn't want to cum yet.

Susan almost cried out "No!" as she felt it leave, but she let it go and hoped that it would soon find its way into other, deeper openings. She wondered, Maybe Alan should stick his thick pole into my asshole instead. That's not really a violation of the boundary rules, is it? He's allowed to touch me on the butt to get my attention, so isn't sticking his penis into my anus and pushing it in and out just another way of touching my butt? It certainly would get my attention! Maybe I should tell him that from now on, in order to get my attention he has to fuck me up the ass! But still she didn't talk.

Now that Alan grabbed his penis to pry it from her butt, he couldn't let go. With one hand, he began to stroke himself and, with the other, he began to explore her ass crack. He quickly found her anus and fingered the opening. He was so aroused by the ass that he even considered buttfucking. However, he decided he shouldn't dare insert his penis there. That might cause her to freak out and end all this fun, he thought. If only he could have read her thoughts!

He pistoned a hand on his penis in time to his other hand pistoning in and out of his mother's asshole. He imagined that he fucked her asshole. He considered the idea to be gross, unclean, and "gay," but his feelings had started to waver. Certainly, the fantasy of doing it was very powerful for him.

Meanwhile, Katherine knew that her mother was far too occupied to look back around her way, so she pulled the thin fabric of her bikini aside and allowed herself to finger her pussy busily. She tore her bikini top off and frantically rubbed her boobs, without a care for who saw her or what they said.

Suzanne also badly wanted to fuck herself but still held back because she knew Susan could see, if she ever came out of her throes of ecstasy long enough to look up. The way the lawn chairs were positioned next to each other, it was hard for Susan not to look in Suzanne's direction if she ever lifted her head. But just the view of Alan on his mother caused Suzanne's juices to flow again. She found the sight of Alan repeatedly giving Susan the most intense orgasms extremely arousing.

But Suzanne's restraint could only take so much. When Alan began to pay considerable attention to Susan's ass and backside, Suzanne reached behind herself and began to play with her own ass as she watched. As Susan began her orgasms, Suzanne plunged her hands into her own pussy from behind as if she did herself doggy style. She started to have her own orgasms and hoped that Susan was in too much of an erotic fog to still remember that her friend sat less than five feet away.

So everyone masturbated themselves to climax at roughly the same time. As Alan reached a climax, straddled over his mother, he unconsciously sat up a bit and pointed his penis down onto her butt. He sprayed his seed all over her ass like a fire hose. It was almost as if he had to hit a moving target, because her whole body shook so fiercely. She was already lost in a continuous series of orgasms from having her son passionately explore every inch of her body and when she felt Alan's semen splash onto her ass, she thought for sure that she would pass out. She'd tried to keep quiet, but she couldn't help but gasp out several loud screams.

Katherine and Suzanne both sat up and watched the sight as they both climaxed themselves into ecstasy. Again, Suzanne was reasonably satisfied. For one thing, she could still taste Alan's cum in her mouth. But Katherine felt her fingers just weren't enough compared to the real thing.

Alan was so amazed that he sat back for a minute and admired his handiwork underneath him. Between his torrent of cum and Susan's own juices dripping down, Susan's butt looked like something out of a gang bang movie scene. She certainly didn't look very motherly.

Alan thought he heard her mumbling, "Moooo, moooo, moooo," but couldn't figure out what that meant.

CHAPTER 7

After a few minutes, everyone calmed down and recovered. Yet still, no words were said by anyone. Luckily the radio still played, or the silence would have been deafening. Susan, in particular, had never felt so good in her life. She thought for sure that her intense experience was over and Alan would move on to Katherine.

But Alan wasn't done. He decided that his fantasy of covering her in cum instead of lotion could become real. He said, "Mom, I'm applying some more lotion here," and he began to rub his still-hot seed into the skin of her butt. As she realized what he was doing, she quickly regained her intense erotic buzz.

Susan still kept her eyes closed, but now that she'd regained some consciousness, she was well aware that Suzanne at least must be watching her closely, if not Katherine as well. Even though this disturbed her, it simultaneously turned her on.

She thought, Certainly Suzanne can see that my butt is just completely covered with my son's jizz! Here I am, buck-naked and with my ass high in the air so my son can coat every inch of it with his sperm. Can I get any more depraved than this? I think not. God, forgive me, but if Alan can get hard again... Hell, what am I saying? Of course he's going to get hard again. This is my Tiger we're talking about! Anyway, WHEN he gets hard again, if he wants to fuck me doggy style like this, I'm just going to have to let him. I don't care if Suzanne is watching. I don't care if I'm going to hell! It feels too good to say no. At least do me up the ass, Son! Fuck your mother's asshole! And if you don't have the balls to do that, then get off of me altogether, because I can't stand the torture of your penis being so close to heaven.

But Alan neither fucked her nor left her. He just kept rubbing his cum into her skin. He had cum so much that there was too much cum for just her butt, so he massaged it into her thighs as well. She was like putty in his hands. Every time he strongly kneaded her flesh, she let out a loud moan of intense joy.

He went right up to the edge of her pussy and rubbed his seed in with her own copiously flowing juices. He was glad that she was infertile, so he didn't have to worry if some of his sperm found its way into her and made her pregnant. He pushed some cum directly over her asshole and watched as the stream rolled down along her crack. The rivulets flowed down to her pussy lips and he wondered if much would make its way inside. Her clit became even more engorged than usual. It stuck out as if it cried out to be sucked or rubbed vigorously by the shaft of his penis. But he still didn't dare touch her fuck hole, for fear that doing so might make her end the whole thing. Again, things would have been very different if he could have read her thoughts.

"Tiger, what kind of lotion are you using there?" she finally asked him, but her tone was playful, not accusing. "I don't know if the kind you're using is really so PROPER!" She nearly shouted the last word as she shuddered to yet another orgasm. Now that her orgasms had started it seemed they would never stop.

"Oh, don't worry, Mom, my cream is the best. It even tastes really good. Would you like to taste some? I could put some on my fingers and you could suck it off with your mouth." As he said this, he put a big gob on his fingers and ran it up and into her butt crack. He even stuffed some of it into her anus.

"Oh no, Alan. Please don't." Susan panted heavily. "Please don't stuff your cream, your tasty cream, in my mouth! What would people think? So wrong. So wrong to fuck your mommy's mouth. No! Not yet. Later! Fuck it tonight! All night! Her second pussy will be waiting for it. But now just keep doing what you're doing to my ASS!"

"Oh, you mean this?" Alan plunged his cum-soaked finger all the way into her asshole.

"Yes!" she cried out. "YES!" But then she thought of the eyes of Suzanne and Katherine on her, and said, "Um, I meant no. So good! So good! But you'd better stop! Please don't... Uh, take advantage... Uh, Oh! Uh, of your.. God! Fuck! Poor, defenseless mother! Yes!"

Her whole body shuddered and shook so violently that it seemed to Alan like she had been churned by a giant blender on a puree setting. The main reason she discouraged him was that she simply couldn't take any more stimulation - she felt like she would literally lose her mind to lust. When it was over, her senses returned after such a dramatic departure that she felt as if she'd died and been reborn.

She opened her eyes and tried to make sense of the world. The first thing she noticed was the sound of Alan casually say, "Okay, I'm done anyways." Then she felt him hop off of her. She could hardly believe it.

She felt such an intense sense of loss as the pressure of his body on hers lifted that she wanted to cry. How long has he been on me? she wondered. What kind of naughty things am I allowing to happen? What the hell did we just do, for crying out loud? What will Suzanne think of me now? Does it really have to end? She just panted and recovered a bit. Then she realized his legs still hadn't been covered with suntan lotion yet.

"Tiger ... your legs!" It was the last thing Alan expected her to say. Then he realized how hot and exposed to the sun his legs were. They were dangerously close to being sunburned.

As she regained control of her mind somewhat, now that he was off of her, she said, "Tiger, lie down where I was and I'll do your legs before they burn." Her tone was firm and uncompromising.

Alan looked at the lawn chair and noticed a huge wet patch on the lawn chair that was his mother's cum. He lay down on the chair, which made the cum stick to his lower stomach. The chair was made of horizontal plastic slats and most of her cum had fallen between the slats and onto the concrete floor. But enough remained on several of the slats that it seemed almost like he had laid down on a puddle.

His mother sat on the ground next to him and began to apply lotion to his feet. Her thighs and abdomen were slick and wet with her cum, but she didn't care. She gradually worked her hands way up to his butt, but because she was so sexually exhausted, didn't spend much time there. She used this as an opportunity to slowly come down from her intense erotic high.

She very much wanted to strike up a casual conversation with Suzanne, to make it seem that the situation was normal, but she was too afraid to even look in Suzanne's direction, guessing correctly that Suzanne was likely to make some kind of wry observation, like, "My, aren't we having fun?"

Alan turned over. His penis pointed straight up into the air and his bathing suit hung uselessly below it, only covering his balls.

Susan gasped in delight at the sight of his hardness. Then, as if her hands had a life of their own, she began to apply oil over the front of his legs and started again at his feet. She quickly covered him up to the edge of his balls. Then she sat there and stared openly at his penis. She thought about her boundaries and the need to obey them, but she felt her resolve quickly slip away. Alan lay back with his eyes closed and silently prayed.

Suzanne spoke up. "It's not a matter of whether you want to suck his cock or not, or whether you enjoy it. What's important is what's good for Alan. He needs to be stimulated many times a day. Now is your chance to help." Suzanne completely failed to mention taking Alan inside for more privacy, and Susan forgot about that option, too. All she could focus on was the penis in front of her. She still didn't even turn to look at her best friend.

Suzanne was like the little cartoon devil on Susan's shoulder, but there was no corresponding angel on the other shoulder to tell her no. Susan thought, I can't believe this is continuing. I've died a thousand times already today. She closed her eyes and reached out with her hands to jack her son off. Her logic was, This is much better from a moral point of view than having him fuck me. Anyway, I have to reward Alan for making me feel sooo good. If he wants my mouth, it's not for me to say no.

She wanted to cover his prick with lotion first. But it seemed her mouth had a mind of its own. It beat her hands in a race to his penis and soon she began to suck him off contentedly. Alan had just come, so his penis had greater endurance now. But Susan battled to defeat his penis.

Inspired by what she'd seen Suzanne do earlier, she did things with her tongue that she never did before, things that she didn't even realize she could do. Again, thinking of Suzanne's superior technique, she pulled out Alan's balls from inside his suit and began to play with them as well. Then she used her other hand and reached into his ass crack. A lingering sense of restraint and acute awareness of the fact that Suzanne watched from only a few feet away stopped her from putting her finger in his anus, even though she'd done it before.

But then she thought, Why should I deny my son anything? He made me see stars, and God dammit, I'm going to make him see stars with the best cocksucking ever in the history of the world! If I have to fuck his ass with my finger to help, then dammit I'll do it, even if it shames me in front of Suzanne. That's just tough shit. My body exists only to please him now. So she plunged a finger deep into his butt, found his prostate gland and stimulated it. But she still kept her eyes closed in embarrassment and tried to pretend that no one could see her ass probe.

Susan decided she had to better her friend in something sexual. I'm not gonna let Suzanne be a better cocksucker! she thought fiercely. My Tiger has to realize he needs to come to his mother for ALL of his cocksucking needs!

She pulled his penis deep into her mouth and then almost all the way out, again and again. Then, she decided she had to try something new, if she was going to be a wonderful cocksucker for her son. She figured that if Suzanne could deep throat him, then so could she. So she stuffed his penis as deep into her mouth as she could get it. But she had no idea how to deep throat properly and gagged immediately. She had to give up the effort, for now. To make up for that failure, she sucked on his balls. Alan found that surprisingly pleasurable.

Susan thought to herself, How does Suzanne do that? There's no way to put a penis down a throat. She felt an urge to immediately ask her friend and that caused her to remember anew where she was and who she was with. Oh dear! Suzanne is really right here with us! And so is my Angel! I'm sitting here, sucking off my own son, I actually have one of his BALLS in my MOUTH, while my daughter and best friend watch me! I can't bear to check, but they MUST be watching. The shame! What have I become? I have truly fallen. Completely fallen into sin and lust. Please forgive me, Lord! But Susan didn't stop. In fact, the thought of being watched only propelled her forward with even more lust.

Her efforts, especially the way her tongue played with the tip of his penis, soon paid off. Alan began to cum and Susan saw another opportunity to better Suzanne, since her friend had failed to take in all of his cum when it was her turn. She held on for dear life as he shot a big, hot wad of cum into her mouth. She took it all and didn't even miss a drop. One of her hands drifted to her crotch and, when she touched her clit, she exploded into another orgasm. It only took the slightest touch. She managed not to scream this time, for fear that she might do harm to her son's penis, but she breathed so heavily that it seemed as if she was on the verge of hyperventilation.

She lay down and plopped her head on his legs, utterly exhausted. She could scarcely believe that she'd cum so much in such a relatively short time. It looked a bit odd that she still had a bikini top on and no bottom. But that was just forgetfulness - she would have ripped her top off if she'd thought about it.

For the moment she had lost all moral restraints and would have done anything and everything Alan would have tried with her. All she could think was: It tastes so good! I want more! More...

CHAPTER 8

Alan came to life, as if from out of a dream, and looked at the world around him. His mother's sticky juice was on two sides of him now. He suddenly felt gross to be so sticky. He looked at his emotionally and physically spent mother as she rested near his feet with her eyes closed and thought of all the semen he'd slathered all over her, even though it had worked into her skin and couldn't be seen anymore. Her own juices, though, were visibly all over her and she looked like a mess.

His mother repeatedly licked her lips, lost in deep thought. Yeeeeesssss, she thought with complete and utter satisfaction. This afternoon has been the best, most pleasurable thing I've ever felt. Forget about fucking - that was better than any fuck I've ever had. I'm going to concentrate all my efforts on cocksucking now. It's soooo good! That'll keep me more than satisfied. Yes, Son, you don't know it yet, but your mommy's your happy little sex slut now. My son has conquered me with his potent, cum-filled fuck stick! Or maybe you do know it, Son, because your mother is such a shameless hussy, blowing her son right in the open, in front of everyone!

I love it! I'm going to make you feel so good, every day! ... I'm like a junkie needing another fix. I'm dead to the world now, but I've got to feel like that again. Soon! I'm a sex junkie! Yes. Sex junkie. Sex cow. Sex slave! Sex, sex, sex! Yes! Sex with my son... Despite all that happened, that last thought sent a shiver of excitement down her spine. Yes. He's going to fuck me. My own son is going to fuck me so deep and so hard that I'm going to DIE of JOY! YES! But she had no energy to move and just reveled in these thoughts.

Alan looked up at Suzanne and saw her calmly sit back with her sunglasses up on her forehead. That was all she wore. She looked and smiled directly at him. She gave him a knowing wink and he winked back. Alan had had a great time, but he didn't fully fathom what a transcendently orgasmic time Susan had just had with her multiple orgasms beyond count. Suzanne, though, had a much better idea and was very jealous. Even Katherine, from her poor angle where she sat, could tell something important had happened.

Alan looked over at his sister and saw her apparently quickly move back into a sleeping position. Finally stripping off the ineffectual bathing suit altogether, he announced, "Thanks, Mom! That was great. You were super. I'm going for a swim."

He bounded nude into the pool and cannonballed in with a big splash. He swam quite a few laps in the pool. The water made him feel completely fresh and alive. He also had never swam naked before in his life and found it extremely invigorating. When he finally stopped for a pause, he looked around to get his bearings and saw that his mother and Suzanne now both stood in the pool as well. They caught his eye, and smiled. He was happy that both of them seemed happy, naked and unconcerned, despite all that had just occurred.

What Alan didn't know was that after he dove into the pool, and while he swam his laps, Suzanne hurriedly got up, scuttled across the back porch and into the house, and grabbed her purse in the living room. She took out a small egg-shaped vibrator and pushed it up into her pussy until nothing could be seen of it from the outside. So now she stood there in the pool with a vibrator designed "for the woman on the go" throbbing deep inside her.

He swam up to where the two women stood next to each other. Their boobs hung just above the surface of the water and bobbed up and down like a line of four giant buoys. He noticed that his mother's bikini top was now off, but looking closer underwater, he saw her bikini bottom was back on. Suzanne was still completely nude.

The four naked and lined up tits were truly an unprecedented sight to behold and his exhausted penis was hard again in seconds. He was struck by how similar their bodies were to each other. No wonder they're friends - it's like they have the exact same bodies. And they're both so unusually tall. Katherine, too. It's a good thing I'm over 6 feet myself, or I'd be pretty intimidated by their sheer size.

Suzanne spoke. "I was just telling your mother that it isn't fair. Seems like she got a much better rub down than I did! MUCH better."

Susan blushed. She appeared somewhat rested and recovered. "It was ... nice, very nice ... but I'm afraid it can't happen again."

"What?" both Alan and Suzanne said at the same time. Alan figured for sure that her taking off her bikini top was a sign that things would get wetter and wetter all day long. And he wasn't thinking of the water in the pool.

"You heard me," Susan continued. "We need to maintain boundaries, and I'm afraid I forgot my own rule, that Alan is not allowed to touch me in certain places. That can quickly lead to even more boundary violations, as we saw today. Why, Alan, you almost put your fingers in my... in my you-know-where hole. And doing this out in the open in front of everyone, it's much too improper. ... I understand we have to get you off as many times today as we can, and that's fine. I'd love to give you as many blowjobs as you want, and I hope you'll, uh, you can..."

Her mood had swung so much that she was now embarrassed to admit that she'd had her own orgasms. "Um, I hope you can make me feel good, too. But we can't just do it willy-nilly. We have to have rules."

They saw that she was serious. Somehow she had rediscovered her self-control. Once Alan had left her presence, it was like a fog of lust had lifted from her brain and all her usual after-the-fact doubts had come rushing back. She was ashamed that she'd let Alan get away with so much in full sight of Suzanne and possibly Katherine. She worried she'd lost some of her authority. She was even more ashamed that she'd luxuriated in the thought of being fucked by her son.

Alan was glad that he hadn't just reached out to play with their boobs, as he was about to do. Great, more teasing, less satisfaction, he thought bitterly. He started to say, "But..."

"No buts! Laying out here together and swimming and all is fine, but us ladies are more than capable of putting on our own lotion, thank you very much!"

Looking to lessen the defeat, Alan asked, "What about the back? Nobody can put lotion on their own backs."

"Okay, the backs. But that's it."

"And what about Katherine? I covered both of you, but I still haven't covered her, and I'd promised."

Susan vacillated. "Okay, I guess that's only fair. But keep those boundaries in mind this time and keep her bikini on or you'll both be in big trouble! And this is the last time you do this." At heart, she was a big softy.

Alan hopped out of the pool. He figured that he'd better start with his sister right away before his mother had a chance to change her mind. Katherine sat up in her chair in anticipation of Alan's ministrations. She'd been naked, but she put her bathing suit back on after she overheard what Susan said. She tied her top on as tightly as it could go, so her nipples could be clearly seen.

"You need some more lotion or you'll burn up," Alan said as he provided the thin excuse to explore her body.

Katherine was frustrated that she had a fairly ordinary bikini, instead of the impossibly small kind Suzanne had found and bought for Susan as well. However, Alan didn't really mind. He figured that given everything else that had just happened, he could take Katherine's top off in a few minutes regardless. Susan would have to be extremely hypocritical to complain.

Alan sat next to Katherine's lawn chair and put a big gob of suntan lotion on his hand. While Susan talked to Suzanne in the pool, Katherine quietly and wickedly said to him, "Hey, Big Iron Spike Brother, why don't you give it to me like you gave it to Mom?"

"I wish, Little Sugar Walls Sis. But she just told me 'boundaries, boundaries.'"

"Yeah, I heard," whispered his frowning sister. "That's not fair!" With a whisper even more quietly straight into his ear, she added, "Your fuck toy is so horny. Her hole is so empty. It needs a filling of brother-cock."

Alan was a bit shocked by that, but played it cool. He whispered back, "Well, let's keep our eyes open for an opportunity and maybe we can still have some fun."

Katherine lay down and Alan straddled her. As he was naked, he made sure to rub his hard penis all the way up the inside of her leg as he moved up her body. It eventually rested on the inside of her thigh. She whispered, "Mmm. Just a few more inches up..."

"Alan! Your bathing suit?" his mother yelled at him from inside the pool. Reluctantly, he got up, put his tiny European-styled suit back on and then straddled his sister again, sitting on her legs below her butt. His penis immediately popped out and he left it that way, in the exact same position it was in before he put the suit on.

So he began to cover his sister all over with lotion. He could hardly believe after such intense encounters with one gorgeous woman and then another, he would immediately do it again with yet a third.

Luckily, for him and his sister, Suzanne and Susan were tired. Susan especially was wiped out after so many intense orgasms. They soon retired to their lawn chairs. For a while, both turned their heads around and took frequent peeks at what Alan did to Katherine.

Alan's greatest concern was with Susan, who was worried again about boundaries in the wake of her incestuous intercourse fantasies. Her resolve was also greatly strengthened by the fact that now that it was her daughter who had the fun and not her. Despite the fact that no less than a square foot of clothing was between the two siblings, nothing too risqué appeared to happen, so Susan was somewhat mollified. She turned her head less and less and finally stopped looking altogether.

Alan eventually decided that Susan had fallen asleep. He wasn't sure about Suzanne, but the important thing was that Susan was now out of it.

By the time Alan was sure Susan was asleep, he was already done applying lotion on most of Katherine's body. But, cleverly, he had saved the best for last: her tits. He wordlessly took her bikini top off and gave her a secret wink.

When it came to his sister, he knew she was willing to go as far as he wanted, and then some. After he squirted a big gob of coconut-flavored lotion into his hands, he began to rub vigorously. He liked to imagine the lotion was his own seed. But, unlike with Susan or Suzanne earlier, he didn't feel the need to hold back much, now that no one seemed too terribly interested in them.

After he slathered her tits with the oil, he devoted his full attention to her nipples. He pinched, pulled, sucked and bit them until Katherine was ready to scream out from both agony and ecstasy.

Alan would occasionally look towards Susan and Suzanne's lawn chairs, since he faced that direction anyway, but all he could see were the backs of their heads as they apparently still lay asleep.

Katherine closed her eyes so she could fully concentrate on the tactile sensations. She was afraid to speak much, for fear of drawing Susan or Suzanne's attention. So, instead, she had fun directing her thoughts to Alan and pretended that she could control his actions with her mind.

That's it, Brother. Touch me there. Tweak it - yeah! You know how to turn me on so well! Now scoot forward. Put your cock right in my hole. You know you want to do it, so do it! Come on! Don't be a chicken! Fuck me right in front of Mom and Suzanne! What are they going to do? They're only going to fight over who gets to be supremely fucked next - you know it. Come on, just scoot a little. Slide it down, right over my smooth, shaved skin. Oh yeah, and do that too! So good!

Alan more or less followed her commands, not because she had any powers of mental telepathy, but because he wanted to do the same things she did. Sitting as he was below his sister's crotch, yet reaching up to her boobs, it was only natural that he would scoot forward and bring his thick rod within inches of her pussy.

With only one hand on her boobs, he brought the other to his penis and began to rub his shaft around the entrance to her love hole. With another glance at his sleeping mother, he poked the tip of his penis right on his sister's pussy lips and pushed the fat and engorged lips even further open.

Her pussy was already really wet from his ministrations. She was nearly delirious with anticipation. As the head of his penis slid over her wet inner thighs, the feeling for Alan was incredible. He looked down and saw pre-cum ooze from the head of his penis and mingle with her juices. He grew even more erect, if that was possible. He could see the penis throb as it literally bounced up and down on her wet and juicy pussy.

"Hey, Big Beef Injection Brother," his sister whispered very quietly, "do you want to fuck me right now or what? I'm game, if you are. Let's do it!"

He felt playful and cavalier. He whispered back, "I don't know, Little Velvet Tunnel Sis. Have you been a good girl?"

"If by good girl, you mean a good and obedient fuck, a willing fuck toy creaming at the mere thought of getting repeatedly speared by my very own brother, then yes."

Alan was tempted. He looked around and realized that it wouldn't be too crazy to fuck her. They just might get away with it. But then he imagined Susan discovering them, and yelling at him in red-faced anger. He realized just how insanely dangerous it would be to fuck her. "Too risky," he whispered and scooted his body forward until his penis was up beyond the entrance into her. But not by much – his penis now lay on top of her smoothly-shaved skin where her pubic hair had been, his pre-cum now flowing freely towards her clitoris.

In her mind, she cried out, No! Bring it back! Stick it in! Fuck me! Take me! Do me! Do your sister! Your fuck toy! Don't you want to fuck your sister? I don't care who knows or who sees! I love you and I want you to have me! All of me! Bring it back! But she did care who knew, at least somewhat, because she kept these thoughts to herself. She was much like her mother in this respect: thinking much nastier thoughts than what she was willing to say out loud.

Katherine was now too excited not to get her hands busy, too. She grabbe
