Incestuous

The sound of screaming kids and the smell of bacon woke 18 year old Sandy Sweet from a particularly great night of sleep. She stirred beneath her sheets, yawning and stretching her naked body as sunlight poured into her room. It took her a moment to remember that her house was full of visiting relatives from out of state. She could hear footsteps rumbling up the stairs toward her room, and suddenly her bedroom door flew open and her two younger cousins, 7 year old Betsy and 8 year old William, bounded into her room. They excitedly raced toward her and jumped onto her bed.

"Sandy! Sandy!" they shouted, crawling all over her but either not noticing or not caring that she was completely naked under her sheet.

"Good morning, munchkins," Sandy said, rubbing her eyes.

"Uncle Steve is taking us to the mall later," Betsy blurted out.

Little William fidgeted excitedly. "He said we could come wake you up."

Sandy didn't seem to really care either that she was naked under her sheet, which fell below her shoulder when she sat up.

"I can't remember the last time Daddy took me to the mall, you lucky ducks."

"Come on, Betsy! Let's go!" William was too excited to sit still for long, and the two of them bounded off together out of her room and back down the stairs.

Sandy just smiled at her cousins, and threw the sheets back. Still naked, forgetting her bedroom door was left open, she stretched one more time in front of her full-length mirror. She loved how her body looked, tone and fit from being on the track and swim teams all throughout high school. She had the best abs of anyone in the school, at least that was what her friends all said. She was one of those crazy people who actually loved working out and running. She was too busy admiring the lines of definition in her stomach and her small but cute boobs to notice the reflection of someone in her mirror standing at her doorway.

"Hey you," came a deep voice that startled her.

Sandy spun around and almost yelped, though she didn't bother to cover herself at all when she saw that it was just her brother, Sam. Sam was 19, and like his sister, very athletic. He played football and basketball a lot, and while he wasn't as big as some of the guys on the team, he was cut pretty well. Sandy had caught herself eyeing his body a few times over the years.

"You scared me," Sandy blushed, knowing her brother must have been staring at her naked.

"You're missing breakfast," Sam said. He couldn't help but take a good look up and down his sister's naked body, but he didn't stare too long.

"I'm coming," Sandy said, and picked up a pair of running shorts off her floor. Sam got a nice eyeful of her ass when she bent over, but without another word he left.

It was hot today, like it normally was during the summer, and Sandy usually wore as little as possible. She knew her family, relatives included, weren't prudish about clothes. So she wore only the running shorts she had found and a dark blue bikini top. Her shorts were bright red and a bit loose, so without panties underneath she would have to keep her legs closed or else someone might see her goods.

Hurrying to the bathroom, she ran a brush through her long red hair and had a quick pee before going to greet everyone downstairs. When she went to wipe herself, she noticed that her pussy felt a bit moist. She suddenly remembered why she had slept so good last night. A smile came over her lips as images of her dream flashed across her mind. She had been dreaming about a really cute guy from school, and the dream had quickly progressed to an erotic setting. Normally Sandy didn't have wet dreams, but when she did they were usually pretty intense. She distinctly remembered having multiple orgasms in her sleep, though she couldn't remember how many, while the guy in her dream had done very naughty things to her body. Just thinking about that dream made Sandy squeeze her thighs together as her pussy tingled. She softly split her pussy lips with her fingers, and dipped her index finger into her vagina. Her hole was hot and silky, just like it always was after her frequent masturbation sessions. She contemplated rubbing one out right now, but since she had been summoned twice already, she quickly finished sanitizing herself and went downstairs.

Breakfast was always fun at the Sweet house. Sandy's mother, Susan, was the perfect housewife. She was a fantastic cook and really loved her family, including the visiting relatives. Sandy always thought her mother was beautiful, elegant almost. Her dad Steve was a great father too, a perfect balance of discipline and love, though by now Sandy had him pretty much wrapped around her finger.

All throughout breakfast, little Betsy and William were going on and on about all the fun they were going to have while they were visiting for the week. So far it was just Sandy's cousins and her aunt and uncle that were here, but more family were on their way. She knew that either she or Sam were going to have to give up their bed, or maybe both. But on the plus side, that would mean she would be bunking with her other cousin, Lilith, whose family would be arriving tonight. Sandy and Lilith were the same age, and the two were marvelous friends. They were inseparable when they were together, doing everything together and sharing everything with each other. All of Sandy's first experiences with sexual feelings and kissing and touching another person were all with Lilith, though they hadn't seen each other in almost a year now. Sandy was looking forward to being with her best friend again.

Lilith had an older sister as well, Sandy's cousin Beth. Beth was in her early twenties, the oldest of all the children of the family. Beth had just graduated from college and was going to start an internship at a law firm in the fall. This was probably her last family outing before starting her own adult life, and though she wasn't close to Sandy, the two did get along nicely. Sandy had always heard a rumor that Beth was actually a very wild person, which might have started with her college influences. Secretly, she knew that her brother Sam had a strange fascination with Beth, maybe some kind of crush or something. He had never said anything about it to her, but Sandy could tell by the way he always looked at Beth.

After breakfast, Sandy trotted upstairs and returned to her room. She wanted to shower and get ready for the day, though she wasn't sure what it would include. She quickly cleaned up her room since she might have to let someone else sleep in here. She picked up undergarments and other pieces of clothing from the floor and stashed them quickly into her closet. For how disciplined she was with fitness and health, she was remarkably messy in her room. She was still cleaning when someone cleared their throat behind her.

Sam was standing in her doorway, for the second time this morning.

"Hey Sam," Sandy said, still cleaning up.

"I just wanted to apologize for walking in on you this morning," Sam said, leaning nervously against the door frame.

Sandy just smiled at him. "That's ok, it's no big deal. Those rascals left my door open."

She could tell Sam was fishing for something, so she kept cleaning while she waited for him to say something.

"Do you...always sleep naked?" he finally asked.

"You don't?" Sandy asked, genuinely surprised.

"No, I do." Sam didn't say anything else, but he was glancing all around her room anxiously.

Sandy picked up the last of the clothes on her floor, and turned to face him. "Why do you ask?"

"I dunno," Sam replied, blushing. "It's kinda sexy, is all."

Sandy tried to hold back her flattered smile. She stepped to within a few feet of him.

"I figured I wasn't your type," she said, enjoying his nervous reaction to their interaction.

"What do you mean?"

She shrugged, pretending to be casual but secretly very excited by having a sexual conversation with her brother.

"You know, guys like women with big boobs and a big ass, right?"

Sam laughed. "Yeah, I guess that it typical. But you know I go for the athletic type."

"Like me?"

Sam nodded. "Yeah, I suppose."

Not really knowing what came over her, Sandy reached up and lifted her bikini top just enough to expose her full tits. Without hesitation, she stood before her brother letting him see her naked breasts.

"You don't think these are too small?" she asked, almost sweetly.

Sam's eyes were glued to her tits. He was caught off guard, but seeing his sister naked or almost naked wasn't uncommon in this house. It's just that she had never been this bold.

"Not at all," he said, practically licking his lips. Still, there was some degree of guilt in the back of his mind that this was his sister, and he shouldn't be seeing this.

"You're sweet," Sandy said, just about to pull her top back down. "You know, you get a treat for that."

She stepped closed to Sam and waited, keeping her top open. He finally looked up at her face, but he was utterly confused as to what she was doing.

"Go ahead," she said. "Touch them."

Sam's eyes widened. "What?"

"It's ok, you deserve some boob after such a sweet comment."

Sam was extremely hesitant, but he couldn't deny that he was wondered what touching Sandy's breasts would feel like. He would be lying if he said he hadn't masturbated a few times to the thought of her. And though he had downplayed it earlier, she was exactly his type.

"Hurry, silly," Sandy said, fidgeting just a bit. "Before someone comes by."

Spurred on by the fear of being caught, Sam's hands lifted from his sides and he found his hands descending on her cute little B cups. Sandy almost purred as his warm hands finally touched her boobs, squeezing firmly but otherwise remaining mostly still. Her nipples reacted to the touch, hardening and poking at his palms.

"They feel..." Sam could barely find words to say. "...Uh...they feel great!"

He took a step forward to get a better look as well as a feel. Neither of them realized how excited this was making him, and to both of their surprise, his erection pressing up against his shorts grazed against Sandy's stomach. Her eyes widened, as well as her smile, and she had to fight to look down at what must have been an impressive bulge. She didn't want to embarrass him though, so she fought the urge.

"Geez, I'm sorry," Sam said, releasing her chest from his grasp and trying in vain to adjust his shorts to hide his excitement.

"I'm glad you enjoyed them," Sandy said, lowering her bikini top to cover herself.

"I...um..." Sam finally just stood there, not wanting to turn away and run like an idiot, but still very embarrassed about his erection. Regardless, he remained in place and allowed his sister to finally see his shorts tenting out obscenely.

Sandy's eyes drifted slowly south, and her amused expression with the wide smile turned to one of shock. Her brother's shorts were tenting so far out, she could only imagine how big his penis was. Just as slowly as her eyes had drifted down, they drifted back up to meet his face.

"Wow," she said, not bothering to hide her surprise. "I've never seen you, excited anyway."

Sam was about ready to leave now, not sure where this was going. He certainly didn't want anyone to walk by and see him like this, though. He turned and headed for the door.

"Wait, Sam." Sandy stopped him. "Is that really because of me? I mean, do you really feel that way?"

Sam couldn't look her in the eyes, he could only nod silently.

"Wow, I never knew..." Sandy had never known that he thought of her that way, and considering her own attraction to him, this presented an interesting circumstance. Incest? Could they possibly do it? She didn't know how to feel now, aside from the initial shock and ensuing arousal.

"Don't tell anyone, ok?" he said, his voice sounding very weak just then.

"Sam, I would never..." Sandy approached him and touched his arm. "You have no idea how flattered I am."

Sam smiled at her, but he was still aching to leave and retreat to his own room.

"You're going to jerk off now, right?" Sandy asked, trying to keep him focused on her as long as possible.

Sam's face turned deep red, but he could never lie to his sister. He nodded finally.

"Take me some of me with you," she said, and reached her hand boldly down into her running shorts.

Sam watched in awe as she quite obviously touched herself in front of him, dipping a finger into her pussy and rubbing it around for a few seconds, her eyes locked on his. She withdrew her hand from her shorts and held it out to him. Sam could see, and smell, the silky fluid that decorated her finger. It smelled sweet and milky. He had been with a few girls by now, but none had smelled so sweet.

"Please," Sandy said when he didn't budge. "You're so sweet to me. Let me return the favor."

Sam wasn't sure what she wanted him to do, but his instincts were to suck her finger into his mouth and lick the pussy juice from it. He followed his instincts.

Sandy groaned as he licked at her finger, finding the sensation very arousing. Sam's eyes were closed for a few moments as he savored her taste, and she had to force herself to keep from reaching down to grab his aching erection as it visibly throbbed in its confines. Sam's eyes opened and without a word, just a quick glance up at her face, he turned and left her room.

His saliva dripped from the end of her finger, and Sandy couldn't resist. She closed her door and hurried to her bed, where she pulled aside the leg of her loose running shorts and softly pressed her wet finger against her clit. Sam's spit felt so sexy against her nearly bare pussy, which she religiously shaved and trimmed. Her own fluids mixed with her brother's to form a wonderful sheen of lubrication for her to finger herself with. Imagining Sam stroking his big cock a few rooms down, Sandy rubbed herself to a wonderful orgasm that ended with a small stream of clear fluid squirting out onto her bed. She sank back onto her pillow, bathing in the afterglow of her climax. It was so powerful, she was surprised she had never thought of Sam before when she masturbated.

Lazily rubbing her pussy mound, bringing small electric pulses of orgasmic pleasure to her wet pussy, Sandy wondered how far she would be willing to go with Sam. Did he really want to fool around with her? Was it just plain wrong for them to be doing even this much? The timing was horrible, since the house would be full of people by tonight and they most likely wouldn't have a chance to be alone for at least a week. What about Lilith? Would she tell her best friend what had happened? The two of them shared everything, and had interacted sexually with each other on a few occasions. One of the reasons Sandy was so looking forward to seeing her was because they would always spend at least one night talking about sex and even masturbating together.

Just thinking about the last time they had done that made Sandy's pussy throb again, eager for another release. She was already masturbating quite effectively, she was surprised to realize. She had been lost in her own thoughts and her body had been acting almost on its own. This time, she inserted two fingers into her pussy and stretched her hole upwards, her other hand busy flicking her clit from side to side in small, frantic movements. Within a minute, she was softly crying out as her hips thrust upward and her body convulsed. With another more powerful spurt of clear fluid, Sandy orgasmed. She couldn't believe how good it felt, but she was making a bit of a mess on her bed. She had squirted on rare occasions before, but this time it had been powerful and she could really feel the hot burst of pleasure it gave her body.

Panting now, and sweating, she needed a shower more than ever. Every time she showered, it meant at least one orgasm with the shower head. She might not have the strength for it now, though.

**********

In his room, Sam barely got his shorts down around his knees before sitting back on his bed and stroking his dick. The taste of Sandy's pussy on his tongue was more than he could handle, and barely thirty seconds into it he was already cumming. Masturbating under normal circumstances, with porn or just a hot mental image, was usually a short session of stroking, cumming and cleaning up. This time, as the sperm was rising in his shaft and his warm cum spurted out of him, it just wasn't enough. While he shot his load out onto his stomach, his hand kept jerking even through his bliss, and a simple orgasm just wasn't enough. Something animalistic in him spurred him to keep going faster and harder.

With a sudden spark of intensity, he thrust his hips upwards and his hand clamped down on his shaft. His orgasm multiplied within itself, and his vision blurred as he had the real, final orgasm. His load had been minimal up to this point, but now he was firing streams of thick white sperm high into the air and all the way up to his neck. He groaned loudly, his teeth clenched together, still tasting his sister's pussy. He nearly strained his muscles as he came and came, finding hidden reserves somewhere to supply this endless need for cum that his body was demanding. Finally, with a final grunt, Sam finished his orgasm and he just lay there, panting.

He had never before experienced something this wonderful. Could it be like this every time with Sandy? He couldn't keep his mind from racing, thinking of all the possibilities of the two of them together. Surely she had to want it too, right? She had practically been here with him, after all. She knew he was doing, and she had encouraged him to do it. The only thing left now was for them to interact with each other. Sam couldn't wait to feel this good again...

**********

That night, the rest of the family arrived. Another aunt and uncle, and two more cousins. Sandy was thrilled to see Lilith run up to her and give her a big hug. Sam was more interested in seeing Beth, who looked better than ever. Once all of the greetings were exchanged and everyone brought their luggage into the house, the rooms were arranged. One set of parents would be in Sam's room, and another set of parents would be in Sandy's room. To her surprise, all of the cousins were being put in the basement. That wasn't a huge deal, it was a finished basement and there was a big screen TV down there and some couches and lots of room for sleeping bags. The only awkward part would be that Sam was the only boy. The two little ones, Betsy and William, were going to stay in their parents' room on the floor. So only the older kids would be together downstairs.

After a huge dinner, the whole family talked and laughed and were just thrilled to see each other. Sandy exchanged a few sheepish glances with Sam, but he tried his best to keep his eyes away from her. It was difficult though, since he was seeing her in a whole new light now. Sandy, strangely enough, didn't feel all that different now. She had always thought he was hot, and now she might be able to act on that feeling. They were still brother and sister, so nothing had really changed all that much.

Nearing midnight, the parents finally retired for the evening. The kids all changed into pajamas and took blankets and pillows downstairs. Sandy was hauling an armful of pillows when her father Steve stopped her. He touched her arm and brought his face next to her ear.

"Hey pumpkin," he whispered, "Be a good girl to Sam, ok? Don't you girls go teasing him too much."

Sandy smiled. "Ok, dad."

She trotted off into the basement to meet up with the rest of the kids.

It was very cozy down there, with carpeting and soft couches to relax on while watching TV. Sam was already sprawled out on one of them, the remote in his hand as he channel surfed. Beth and Lilith were spreading out their blankets and pillows. Sandy noticed how much the two sisters looked alike. Lilith was skinnier, like Sandy though maybe not as toned. She had dark hair, almost black, which was shorter than Beth's. Beth had lighter brown hair, pulled back in a long pony tail. Other than a few years and maybe a cup size, the two girls were very similar. Beth was more mature, though. She had more of a figure, with larger breasts and a nice round ass. Lilith was more girlish, and would probably fill out just like her sister.

Do you think our parents can hear us down here?" Lilith asked.

"No way," Sandy said, then louder, "I mean, no fucking way!"

Lilith laughed. "You bitch, you'll get us all in trouble."

"No one upstairs can hear us, trust me," Sam said, not taking his eyes or much of his attention from the TV.

"That's good to know," Beth said, winking at Sandy.

All three girls were camped out on the floor, while Sam remained on the couch. They all watched TV with him for a few minutes, the two cousins probably tired from their trip. Or so Sandy thought.

"We should play a game," Beth said, propped up on her elbow.

"Like what?" Lilith asked excitedly.

Sam just rolled his eyes, knowing he wouldn't want any part of whatever they had planned. Sandy remembered what her father had said to her earlier.

"We have to include Sam if we're gonna play something," she said, much to his reluctance.

"Ok, fine," Beth replied, thinking it over. "I'm the oldest, so I should get to choose."

"Come on, Sam!" Lilith said. "Please play with us?"

Sandy wondered if the pure suggestiveness of Lilith's prying was what made Sam sigh and turn the TV off. He rolled off the couch and sat on the floor with the girls, all of them in a circle of sorts. Even sitting directly across from her, Sam didn't dare look Sandy in the eye. She wondered if he had regretted what had happened between them. She hoped not.

"What's the game, then?" Sandy asked.

Beth sat straight up, brushing her pony tail over her shoulder and eagerly putting her hands in her lap. She seemed more playful than Sandy ever remembered her. Even though she was 4-5 years older than the rest of them, she seemed quite content to be spending time with her sister and cousins. Sandy thought that was really neat, and uncommon in her experience. Usually older siblings tried to act superior or indifferent to the feelings of those younger than them. Sam was only a year older than her, so he hadn't really done that much. Sandy wagered he would be very attentive to her if she wanted him to be.

"How about..." Beth looked inquisitively at each of them, studying them to see what they would be up for. "...if we start off with truth or dare, but without the dare. Let's save that for later."

Sam laughed. "That's a game 12 year olds play. Are you serious?"

Beth looked mockingly offended. "I'll have you know that we still played it in college, thank you very much."

Lilith tried to stifle a giggle. "I've heard about some of those college games."

Beth slapped her shoulder. "Shush! I told you that in confidence."

Everyone laughed, but Beth was serious about playing. Sandy had actually never played this game before. The only person she ever would play it with was probably Lilith, and they skipped straight to the stuff most people were dared to do.

"Just to show that I'm not going to wuss out as the oldest," Beth said, "I will let you all ask me a question each."

"Wait, we all have to come up with a question?" Sandy asked. "I don't even know what I'd ask."

"Don't worry about it," Beth said. She crossed her legs in front of her, inadvertently hiking up the football jersey she was wearing as pajamas and showing her white panties to everyone. Sam noticed, but was good about not staring. Still, something about white panties against tanned skin made him hot inside.

"I'll go first," Lilith offered. "I already know so much about my big sister, so I'll have to just ask her the naughty secret stuff."

Beth pretended to be angry at her, but then bowed her head. "I graciously accept all questions, regardless of subject."

"Um..." Lilith tapped her chin. "How many hours total did you spend at college on your knees?"

Beth smacked Lilith hard on the arm, making everyone laugh out loud. Lilith rubbed her arm, but she was laughing too much to show any hurt.

"Ok, just kidding. I already know it was a lot." She giggled, and thought of a new question. "I got it! How old were you when you had your first orgasm?"

Sam was blushing by now, and Sandy couldn't keep from covering her mouth in embarrassment. These were sisters, after all!

Beth was true to her word, though. "14 years old."

Everyone's eyes widened.

"Oh my god, really?" Sandy blurted.

"It was the first time I tried masturbation," Beth answered. "I was damn well gonna figure out how to do it right the first time!"

Lilith was rolling on her back with laughter. Sam was a bit too aroused by this, though, and he just smiled sheepishly. Sandy could see how uncomfortable he was, so she tried to help him out.

"I'll go next," she offered. "What's the most embarrassing thing you've ever done in front of someone?"

Beth thought carefully. "Hmm, well I've peed while someone watched me."

"You peed your pants?" Sam asked in disbelief.

Beth gave him a sly glance. "I didn't say it was on accident."

Everyone was silent for a moment, and Lilith was the first to speak.

"You did that for a guy, you mean?"

Beth nodded. Sam shifted his sweat pants not two seconds later, as the mental image sank in. Beth was freaky!

"Your turn, Sam," Beth said.

Sam coughed nervously. "I have no idea what to ask."

Beth smiled seductively at him. "The subject is, apparently, sex. Think of something."

Sam propped his knees up to hide his tent. "Ok, fine. What's the craziest thing you ever did?"

Lilith leaned forward on her elbows, excitedly listening to her big sister spill the beans about all the stuff she wanted to know about college life. Sandy was equally as interested.

"Ok, fine. I'll tell you all what happened the night before graduation." Beth paused and eyed each one of them. "But you all have to do something for me first."

"I thought we weren't doing the dare part?" Sandy asked.

"This isn't a dare, it's a requirement for the truth game to keep going. You want me to reveal my secrets? Then you have to reveal yours to me."

None of them knew what she was referring to, but to their shock, Beth reached down to her waist and pulled her jersey up and over her head. Sandy's mouth hung open in shock as she stared at her older cousin's bare chest, whereupon sat a very cute pair of firm C cups. She ignored Sam's equally shocked, albeit aroused, expression and Lilith's strangely happy one.

"Yay!" Lilith said. "Naked time."

Beth enjoyed Sam's reaction. "You've never seen a pair before?"

Sam shook his head. "I mean, yeah of course. But I can't believe you're showing them to us."

"Come on, guys." Beth looked seriously at them all, for the first time since the game started. "This is my last hurrah before starting my internship. I want to have fun on this trip. Nothing but fun the whole week."

Lilith was hilariously trying, somehow in vain, to get her oversized t-shirt off. She had it caught around her neck, but eventually her small tits came into view. Sandy had seen them many times before, but she was still surprised at how open these two were being.

"I agree," Lilith said, her hair a mess now.

"You want us to all be naked?" Sam asked. "Is that what you mean?"

Beth shrugged, making her tits jiggle just slightly. They were perfectly firm and round.

"We don't have to do anything you don't want to do. But we could all have some real fun this week if we just agree to be totally open with each other. No hiding anything, no lying, no secrets. It'll be our pact for the week."

Sandy felt her own t-shirt itching against her skin suddenly, the thought of being as open with Beth as she was with Lilith, and had started to be with Sam. She hooked her thumb under her shirt and hesitated.

"You won't judge us or tell anyone what happens?" Sandy asked her topless older cousin.

Beth smiled lovingly at her. "Do I have to prove how serious I am? I'll take the panties off too."

Sam rubbed his eyes. "I can't believe this is happening."

Beth leaned closed to him and nudged her shoulder against his. "See? It's not so bad having to hang around your older cousin, is it?"

"Come on, Sam!" Lilith said, fidgeting in just her blue panties. "We'll do lots of naughty things to you..."

Sandy smiled and finished pulling her t-shirt off. Everyone stared in approval, even Sam, at her awesome body. No one could deny she was hot, with her tight abs and perfect tan. Following suit, Sam pulled his shirt off. Of course, it wasn't quite the same as the girls doing it, but he still had three appreciative looks from them as they saw his muscular chest and arms.

"Wow, you're pretty hunky," Beth said, keeping cool and calm under these odd circumstances. "You're not a virgin, right?"

Sam was caught off guard by the question, but managed to shake his head.

Beth nodded. "Good. Then it's two against two."

"Hey!" Lilith protested. She always hated when her big sister held her sexual experience over her.

"Oh, be quiet, Lil," Beth said. "Before the night is over, you might finally grow up."

Sandy wondered what that meant, exactly. Was Beth planning for sexual activity between the four of them? Her pussy instantly moistened at the thought of them all fooling around.

"Maybe Sandy and I aren't technically virgins either," Lilith said proudly.

Sandy shot a look at her cousin, hoping she would keep her mouth shut. Of course at this point, did it really matter if Lilith let slip that they had experimented with each other before?

"Whoa," Sam said, finally taking his eyes off Beth's gorgeous rack. "You two?"

Sandy blushed, despite the fact that she was already practically naked in front of them all.

"Messing around as kids doesn't count," Beth said, not acting surprised at all. "Even Lilith and I have done that."

Now it was Lilith's turn to be embarrassed, and she glanced nervously at Sandy, hoping she wasn't mad. Sandy didn't know how to feel. The two of them had always confided in each other. Only Lilith knew about Sandy's recurring wet dreams with the multiple orgasms, and even her mild crush on her brother. But Lilith had never said anything about Beth before.

"Sandy, don't be upset." Beth smiled at her. "We've all done stuff with different people. Haven't you and Sam ever fooled around? Even a little?"

Sam choked on his own breath, coughing his surprise out. "Hey now, where exactly is this going?"

Beth smiled, and answered by slowly extending her legs out in front of her and gently tugging her white panties down her hips.

"Where do you want it to go?" she asked.

Sandy found herself drooling at the thought of seeing Beth naked, a feeling she wasn't prepared for. But she couldn't deny the tingling in her belly, and the dampness in her underwear.

"Wait," Lilith said. "Let's all get naked together, ok?"

Beth nodded, though she was eyeing Sam mostly. "On the count of three then."

Each of them looked nervously at the other, and the girls would certainly all be looking at Sam once his pants came off. Still, he was so fucking horny at this point that he would do whatever his hot cousin wanted him to do. If it ended with him cumming, then that was perfectly alright with him.

"One...two..." Beth led the count, each of them ready to strip their panties off and Sam ready to drop his sweatpants.

"Three!"

In a muddled burst of energy, panties flew up in the air and there were four thuds as their bare butts all hit the floor. For a few seconds, the thrill of being naked in front of each other was clouding the reality that what they were doing was totally sexual. Once the thrill died down for a moment, silence followed as Sandy saw Lilith and Beth both staring at Sam. She followed their eyes, and gasped.

Sam sat there naked, his erection proudly at full mast, and there was nothing he could do to hide it. So he sank back onto his elbows and let the girls have a look at his body. He knew how girls reacted to seeing his big cock. It didn't matter if they were related to him, he never grew tired of that reaction.

"Holy fucking shit, Sam!" Beth exclaimed.

"My god," Lilith whispered. "How big is that thing?"

Sandy just stared, though eventually her eyes met Sam's. There was still a strange connection between those two, after that morning. Sandy felt instantly regretful at what she had been missing all this time. She wouldn't pass up any more opportunities.

"Bigger than any I've had in me," Beth breathed, her arousal clear in her voice. "Well, I think so, anyway."

"Why don't you get closer and be sure?" Lilith teased, though she actually longed to see it closer for herself.

"Sam?" Beth's eyes were locked on his now that he had torn them away from Sandy. "You have to want this, otherwise I'm not-"

Sam nodded his head. "I want it."

Beth looked around at the other two girls. "You guys too?"

Lilith didn't need to nod, it was obvious she was horny as hell. Sandy was hesitant, though. She secretly longed for Sam's body, but in front of her cousins? Her throbbing pussy wasn't helping her judgment any.

"Come on, girls," Beth insisted. "Do you want to lose your virginities or not?"

Lilith clapped her hands and squealed. "Really? Oh, Sammie, I would do love to have you inside me!"

Sam's dick twitched, the thought of fucking all these beauties a bit too much for him.

"I...there's no way I can last that long. I'm about to cum right now."

Beth smiled. "He's right, girls."

Lilith frowned, afraid that her fun would be spoiled.

Beth crawled forward and put her hands on Sam's thighs. "If he's gonna last long enough to pop your cherries, he'd gonna need to let one go first."

Sam groaned, knowing that he was about to actually do what he would only fantasize about. Before her face even descended to his crotch, he knew Beth was going to suck his dick. He felt his balls already start to tighten.

"Oh god, I don't know if I can stand it," he sighed, trying to hold it in.

Beth's hot breath on his twitching boner wasn't helping either. "You want that, Sammie? You want to cum in my mouth?"

Sam clenched his eyes shut, forcing his body to calm down. His legs were starting to quiver under Beth's hands. He wasn't a virgin, by any means. He had been truthful in telling her that. But this was a whole new experience, and he might as well have been one.

Beth's lips closed over his head, and Sam groaned loudly as he felt her tongue begin to slowly swirl along the underside of his shaft. Lilith was watching with intensity, fascinated at the display her sister was putting on. She planned on learning a lot from her big sister tonight. Sandy watched as well, but she was overwhelmed with desire to be the one doing what Beth was doing. How many times had she masturbated thinking about doing exactly this to him?

Sam's eyes finally popped open, and he looked right at Sandy. Her expression reflected her deep longing, and her eyes were almost pleading with him. He returned the look, and then gave in to the intense wave of pleasure that Beth's skilled mouth was giving him. She must have sucked a lot of dick in college.

"Oh my god!" he cried out, and thrust his hips upwards into Beth's face.

"Oh yeah!" Lilith said, cheering from the sidelines. Her hand snaked across the floor and she grasped Sandy's fingers excitedly.

Sandy watched as Beth smiled up at Sam with her mouth full of his penis, and her eyes closed sensually and she groaned herself as his cock began spewing semen into her throat. She sucked hard on him, milking his cum from his balls. There was no hesitation or reluctance on her part, she was completely giving her mouth to him, her 19 year old cousin. In front of her own sister and his as well.

Sam shivered as Beth held on for the ride, letting him shoot everything he had into her mouth, and then resuming her suck job. Without a word, they all watched as Beth sucked on his penis even more, enjoying the taste of his sperm and the pleasure she was giving him. She reached a hand down to her crotch and began rubbing herself. Sandy's eyes glazed over at the obscene show.

"How did that feel, Sam?" Lilith asked.

Sam just sighed deeply, raggedly. "It was amazing. It still is."

Beth purred in his lap, impaling her throat on his dick until she felt his balls against her chin. Sam grunted, and she swore she felt a weak stream of cum leave his cock. His penis tasted sweet to her, much better than the college guys she usually sucked off. Sam's cock was better than any of theirs.

"Come on, girls," Beth said finally, strings of saliva and sperm trailing from her lips to Sam's dick head. "Do it with me."

Lilith quickly obeyed, and began masturbating. She motioned for Sandy to do so as well, but she was very shy suddenly.

"Lil, show Sandy what you like to do when you're feeling especially naughty," Beth encouraged.

Lilith smiled at her cousin, and got on her hands and knees. Propping herself with one hand, she reached the other back and gently began drifting the fingertip of her middle finger up and down her crack. She purred to herself as she enjoyed the naughty feelings that her ass gave her.

"You want to try it with me, Sandy?" Lilith said.

Sam was eagerly watching Sandy, mostly, as Beth's mouth returned to his cock. He stroked Beth's hair softly, but he was watching Sandy carefully. Sandy wanted to make her brother happy, and found a thrill finally in performing for her audience. Everyone else was doing it, she might as well join in.

"Ok, I'll masturbate." She kicked her feet out from under her and spread her legs wide.

Sam's mouth watered as he saw his sister's pussy for the first time. He could see why it had tasted so good earlier. She had the softest, smoothest pussy he had ever seen. She had a nice strip of short hair above her clit, but her pussy lips were nice and big for someone so petite. Sandy smiled shyly at him while her fingers began to explore her pussy.

"Oh god, Sandy," Lilith said, turning her head to watch her cousin get off. "I forgot how nice your pussy was."

Sandy's eyes closed as she gave in to the wonderful feelings her body was giving her. Beth watched eagerly as well, finally pulling away from Sam's cock after it had retained its stiffness. Sam was shocked yet again when she climbed on top of him and sat herself down on his lap. Their faces were inches apart, and her breathing was really turning him on. She guided his cock to her steaming entrance, and gently slipped him inside of her.

"You're fucking?" Lilith said, her attention turned away from Sandy. "Oh my god! Beth!"

Beth ignored her little sister, and softly set herself down onto Sam until their bodies met. She rested on him, feeling him twitch inside of her hot pussy.

"I couldn't help myself, he tasted too good."

Sandy's fingers sped up as she watched her brother fuck her cousin. He had just cum, but he had still been rock hard. Maybe she would have a chance with him tonight after all!

"Tell me something secret," Beth said to Sam, rocking her pussy into him. "I want to hear you reveal something to us."

Sam was pretty hazy by this point, having just cum and now already fucking this hot girl. But there was nothing to hide anymore. What they were doing was wrong enough, so there wasn't anything that he should feel guilty about now.

"I..." Beth's pussy gripped him right as he tried to speak, and the breath was taken out of him for a moment. Her tits in his face made him thrust sharply upwards into her. "I tasted Sandy's pussy on her finger."

Sandy's fingers were a blur now, rubbing her clit furiously. Hearing Sam reveal something so forbidden was too sensuous for her to handle, and instead of being embarrassed, the revelation made her intensely horny and she could feel her pussy contracting.

"Yes..." she hissed. "I fingered myself and let him taste, so he could jerk off thinking about me."

Lilith's gentle drifting fingers turned to focused probing, and she was openly spreading her cheeks and touching her asshole. Beth kept her pace fucking Sam, but her smile said that she enjoyed hearing his revelation.

Good," she breathed. "Good boy! Secrets make this all the more enjoyable, don't they?"

Sam just nodded his head, concentrating on the feel of her smooth pussy dragging along his shaft.

"It's my turn now," Beth said, still fucking Sam but slowing down a bit. "Lilith and I ate each other's pussies when we were younger."

Lilith squealed in delight, remembering how good her sister was at licking her clit. She was so close to cumming, she couldn't even speak.

"How young?" Sandy asked, actually interested in knowing but also incredibly aroused by the thought.

"Too young," Beth said. "Before you and her."

Sandy felt better knowing that, actually. Not that they had any real sexual relationship, at least until this point. But now it wasn't like she was doing something behind Sandy's back. Sandy wanted to be completely open now, just as her brother had been, and as Beth and Lilith were being.

"I've been dying to fuck Sam for years now," she blurted.

Sam's eyes shot over to her, though Beth was still riding him. Beth smiled, and stopped moving on him.

"You should get to do that, right now," Beth said. She glanced down at Sam. "That ok, stud?"

Sam just nodded, the thought of fucking Sandy sending a new pulse of pleasure through his groin as Beth slid off of him. Sandy cautiously approached her brother, eyeing his big dick. She wanted to feel it so bad inside of her, she didn't care how bad it hurt the first time.

"Do it, Sandy!" Lilith said, right as she started to cum. "Oh god! Fuck Sammie!"

Beth sat next to her sister and gently stroked her back while she climaxed. Lilith came down from her high and laid her head in her big sister's lap. She closed her eyes for a moment, loving the warm feelings that were in this room right now.

Sam licked his lips as Sandy came over to him, her naked body looking delicious. Her pussy smelled sweet even from a few feet away. Beth's cream was all over his dick, a fact that Lilith didn't want to miss out on.

"Wait!" she said, startling everyone. She crawled over to where Sam and Sandy were. "I get a taste before this happens."

Lilith didn't hesitate to suck Sam's cock right into her mouth, savoring the taste of her sister's pussy. She had never sucked a dick before, but this wasn't about giving pleasure to Sam. She wanted to be able to say she had licked pussy juice that wasn't her own off a penis at least once in her young life.

"Ok, Sandy," she said, satisfied. "Fuck your bro good."

Sandy smiled, and leaned forward to kiss Lilith on the mouth. They shared a deep, wet kiss that included the sharing of Beth's cum. But Sandy was ready to fuck now. She needed to. Sam felt the same way.

Sandy sat on Sam's lap, his big cock sprouting up between their stomachs. It was as if the two of them were alone in the room now. Their eyes met, and Sandy's hand gently touched Sam's penis. Fluid from the tip leaked out onto her belly button where it was resting. She smiled at him, enjoying this closeness.

"Are you going to fuck me, big brother?" she asked seductively.

Sam groaned, feeling her hand squeeze his cock. "Please, let me."

Sandy lifted herself just a bit, positioning his penis at the steaming hole of her pussy, and very carefully began to slide down his pole. He was stretching her little virgin slit immensely, making it hard to completely enjoy the moment. But Sandy's determination stuck, and she bottomed out finally on his pubic hair. Finally, they kissed.

They didn't even hear the slurping sounds behind her, as Beth and Lilith 69'ed right next to them. They were totally focused on each other, on the thickness of Sam's penis, and on the slick friction of Sandy's pussy as it slid up and down on him. Fucking Beth had helped him get ready to cum again, and Sandy's tight pussy that he was claiming before any other man ensured that he would be filling her sweet little hole with his cum any minute.

"Fuck me, Sam," she whispered into his mouth. "Cum inside of me."

"Oh god, Sandy..."

"I've wanted this for so long," she purred. "You have no idea. I masturbate every night thinking about you."

Sam sped up his pace, spurred on by her words. "I've wanted you too. I've never cum so hard as when I've jerking off thinking about you."

"You can have my pussy any time you want it, Sammie," she said, her voice reaching that shrill peak of orgasm. "My pussy, my mouth...even my ass, baby. Anything you want!"

Sam cried out, his balls aching to release another load. Their eyes met as they both reached their crescendo, and Sandy's pussy exploded around Sam's spewing cock. They both grunted and groaned together, sweat from their stomachs mingling and saliva trailing between their lips. Sandy's pussy eagerly accepted Sam's generous load, throbbing and convulsing around his shaft to coax out everything he had. Sam held onto Sandy's hips as he fired away inside of her.

After, when their focus expanded and they remembered their cousins, Sandy turned to see the two of them still in the 69 position, but completely focused on the show. She blushed, but held brother tightly in her vagina.

"Fucking wow!" Lilith said, fluid dripping down her mouth.

"Congratulations," Beth said proudly. "Day one is over, six more to go."

Sam sucked on Sandy's tits as he continued to twitch inside her tight pussy. Sandy breathed in relief, mewing as her brother fed at her breasts. She squeezed his cock tight inside of her body, holding him there and keeping their bodies locked together.

"I love you, Sam."

**********

"Hey you guys, check it out!" Lilith whispered.

Sam and Beth both turned their heads for a second when Beth's little sister called to them, pausing in mid-fuck. Sam was on top of Beth, having been fucking his cousin for the last five minutes. They had all fallen asleep not long ago, but he awoke some time later with a raging hard-on. He had started feeling up her sleeping body, and when she stirred awake and smiled at him, he had wordlessly stripped off her pajamas and went about eating her vigorously.

The fuck session earlier had started a fire in him that had begun with his sexual feelings toward his sister. But their adventurous older cousin Beth had taken things farther until he had committed incest with Sandy, his younger sibling. Sandy was sleeping still, but Lilith was sitting near her, fascinated by something. Sam pulled his cock reluctantly from Beth's tight pussy, her fluids dripping from it, and crawled over to his younger cousin.

"What is it?" he whispered.

But it didn't take long for him to notice what Lilith was fascinated by. Sandy was asleep for sure, but she was dreaming and making sounds. Beth joined them, her naked breasts pushing against Lilith's arm as she squeezed in for a look. Sandy's body was twitching, and her hips were softly thrusting into the air underneath her sleeping bag. Lilith carefully peeling it back, exposing her naked body underneath a hiked up t-shirt. She had put Sam's shirt on after their passionate sex, a gesture he had found sexy.

Sandy moaned softly, little muffled cries of pleasure escaping her mouth. She was having an erotic dream.

"I've never seen someone be so into it," Lilith said, her eyes locked onto Sandy's tight stomach quivering and her shaved pussy contracting.

"Is she cumming?" Beth asked.

"Wow, I think so," Sam responded, his aching cock throbbing.

Sandy cried out, still in her sleep, and her pussy oozed out thick fluid followed by a squirt of clear pussy juice. She was squirting in her sleep!

"Holy shit," Lilith said, enthralled by what was happening. "She really cums when she has a wet dream."

"She's still cumming, look!" Beth pointed her her cousin's pussy, still contracting and squeezing at an invisible penis.

"God, I just wanna fuck her," Sam said, spreading her legs and kneeling between them.

"Don't wake her up," Beth said, not at all disappointed that they hadn't finished fucking. "Be gentle."

"I want to stick it in her butt."

Lilith gasped, being somewhat of an anal lover. She was still a virgin, of course. But she always played with her butt when she masturbated.

"That is so hot," she replied, openly rubbing her pussy in front of them. "Beth's right, try to do it without waking her."

"That's gonna be kind of hard," Beth said, her mouth watering at the sight of her little sister's pussy that she had licked and sucked years ago.

"She offered her ass to me," Sam said, gently pushing her legs apart and positioning the tip of his penis at his sister's cute little ass. "I just wanna take her up on it."

"Lilith," Beth commanded, startling her sister. "Bend over, I wanna lick your ass while Sam fucks her."

Lilith was thrilled, and totally shocked that her sister would say something so obscene. They hadn't fooled around like this in a long time, but she longed to do it again. She complied, getting on her knees and reaching back to spread her butt for her sister. This was so dirty, she loved it!

Sam groaned, only spurred on by his cousins messing around next to them. But he had to focus on Sandy's butt. He gently pushed his cock up against her tight pucker. He was covered in Beth's pussy juice still, but her ass would need some help. He scooted back a bit and leaned down to lick her pussy first, loving how sweet it tasted. Then he drifted lower and licked from her pussy to her taint, then down to her butthole and back again, before finally just diving into her ass.

Sandy remained asleep, somehow, but her moaning increased as her brother ate her asshole. It was difficult since she was on her back, so Sam cautiously rolled her over to her side so he could get better access. With her butt facing him now, he resumed licking it. His tongue dragged sexily along her crack, finding her little pink anus and slobbering all over it. She came again, leaking pussy juice down the back of her thigh. After a lot of lickinng and sucking and kissing, Sam was ready to stick it in her.

Lilith and Beth were busy with their own horny act, Beth eating her little sister's ass just like Sam. Lilith purred and moaned while her big sister ate her butthole out. Beth was really into it too, going from her ass down to her pussy and back. After a minute of just tongue, she finally inserted a finger into Lilith's ass. Lilith yelped, and a stream of pussy juice trickled down her leg as she came intensely.

"Oh god, Beth!" she cried out. "Fuck my ass!"

Beth smiled, digging her knuckles deep into Lilith's butt. "I bet I know someone who will."

Sam smiled at them, overhearing their horniness but still busy trying to position himself so he could get inside his sister.

"Sam," Beth interrupted. "Come try it on Lilith first, so you know what it's like."

Sam paused his positioning and thought about it. He felt ready to bust a nut already, so if he wanted it to last with Sandy, he should get off first. He hadn't really thought much about fucking Lilith, but seeing Beth eat her out was starting to get to him. He wanted to feel and taste her tight little body.

He carefully moved away from Sandy, letting her return to her erotic dream peacefully, and his eyes locked on Lilith's ass. She eyed him nervously, this being the first time she would have a cock inside of her body. Sam kneeled behind her and immediately aimed his cock at her butt.

"Just be careful," Beth warned.

"No," Lilith protested. "I like it rough. Don't hold back."

Sam glanced to Beth for approval, and she just shrugged. Sam touched the tip of his dick to Lilith's tight ass, and pressed against it. Beth's saliva and Lilith's own juices were lubricating her nicely, and his penis slid right into her asshole about an inch. Lilith grunted, extremely aroused but also nervous for her first time with a boy. Sam couldn't help himself, though, and he thrust into her sharply, his hips bucking involuntarily when he felt her hot sphincter gripping his dick.

"Oh god!" Lilith cried, feeling his hips touch hers. He had buried himself already. Her years of anal play had at least made this more pleasurable than it might have been.

"You ok, sweetie?" Beth asked, stroking her little sister's hair.

Lilith nodded. "Yes, god yes! I love it!"

Sam started sliding back out, her ass dragging filthily along his cock. The whole thing was so perverted, fucking his cousin in the butt, that he couldn't hold back from cumming. He buried himself again and grunted, shooting sperm up into Lilith's bowels. They both came together, Lilith really getting off on feeling him spray her insides. She wondered if it felt this good or better in her pussy. Sam kept himself buried until he had finished unloading into her, and then pulled out. His cum trailed out of Lilith's abused little ass, but she just purred.

"Ok, Sam," Beth said, eager to see him fuck his sleeping sister. "Sandy needs to be awakened by you inside of her."

He just smiled, absently stroking his wet boner and keeping himself hard. He wouldn't need to though, since the sight of his naked sister would only make him hornier. He went back to Sandy, and got into position behind her. He ate her asshole for a bit more, getting her nice and wet, and then touched his dick to her butt. He spread one cheek apart with his free hand, and aimed his cock with the other. The smell of wet skin and Lilith's ass on him drove him crazy, and he needed to fuck Sandy bad.

Slowly, so as not to wake her, he gently opened up her butthole with his penis. Sliding a half-inch at a time, he took advantage of her relaxed state. Her ass was tight, unbelievably so, but it didn't refuse his invasion. Sandy didn't wake up until he was halfway inside of her.

"Sam?" she stirred, finding her dream and reality to be very similar. She had been dreaming about fucking Sam, and it had been wonderful. She had cum many times, and now she wondered how much was real or actually a dream.

"Just relax baby," he said to his sister. "The hard part is done, now you just need to hold still."

She could feel him in her ass now, and his words started to make sense. Her brother was fucking her ass while she was asleep! He was raping her unconscious body, and yet her pussy was on fire thinking about it. Why did that turn her on so much?

Sam groaned loudly as he slid another inch, her asshole clamping down on him when her body began to respond more. She grunted, feeling his cock up inside of her. It was an odd feeling, unlike when he was in her pussy. It felt naughty and dirty, and yet the way her butt responded to the intrusion was so different than she would expect. Each of his thrusts rippled a wave of pleasure upwards into her body, the whole thing feeling him fuck her instead of just her cunt. It was amazing, really, considering how unnatural the act was. She could tell they would be doing this a lot.

"Take it, baby," Beth said, masturbating with Lilith while they watched their cousins pork.

Sandy loved being watched, especially doing something so bad with her brother. She fingered her pussy while Sam busied himself with her butt, but it was hard in the position she was in, being on her side like this. She flipped her leg over and went back to laying on her back. Now Sam could still fuck her, and stare at her naughty bits while she played with them. They both began panting and grunting like animals. Lilith and Beth traded orgasms, one climaxing then the next. They didn't stop until the ass fucking was over.

Sam watched Sandy bring her pussy off, squirting all over the both of them, and finally couldn't take it. He slid all the way into her asshole and ground his hips against her, letting her tight butt milk his cum. He squirted hard into her, somehow finding more cum to give to her. This was the fourth time already since the evening began. Sandy was lost in orgasmic bliss, still squirting her own load all over her brother. Her stream was hot dripping down his stomach to his crotch. The smell of sex would be hard to get out of this basement, especially if they continued doing this for the whole week.

Pulling out of her ass, Sam sat back and took in the sight of his well-fucked sister. Her butthole looked especially delicious, gaping a bit from his thick cock stretching her open. Sandy came down finally from her climax and gently played with herself, feeling how open her ass was and loving it.

"Sammie," she breathed, smiling dreamily at him. "We have to keep doing that."

He sighed, wiping the sweat from his forehead. "Don't worry, I didn't get anywhere near my fill of that."

Lilith and Beth were just watching now, having cum multiple times each. The four of them were all exhausted now, but all very satisfied.

"You guys," Beth said, "we have to get some sleep. But seriously, this is going to be the best week ever."

"How are we gonna keep our hands off of each other around everyone else?" Lilith asked.

"Don't blow this, Lil," Beth said sternly. "No one can know we're fucking. Seriously, it would devastate everyone. They wouldn't understand."

"I still can't believe we're doing this," Sam said. "It's like a dream."

Lilith absently stroked her ass, freshly fucked by Sam. "I never want to wake up."

**********

The four of them finally drifted off to sleep, the girls staying naked even though at any time someone could come downstairs to wake them up or check on them. When Sam awoke first, he stayed sprawled out on one of the sofas and just stared at the three girls. Each had their own special traits, that he found irresistible. Sandy, of course, had a killer body with abs and a soft tan. Lilith had a similar frame, skinny and small tits, but her ass was almost as good as Sandy's had been. Beth was a bit more mature, and had more curves than the other two. Her tits were bigger too, and Sam pondered if he could sneak a titty fuck before someone came downstairs. He decided to jerk off while he thought about it.

Beth stirred next, sleepily looking around as if she couldn't remember where she was. She saw Sam masturbating, and smiled.

"Hey stud," she yawned. "Didn't you get enough yet?"

"No way," he replied, but Beth was already crawling over to him.

"I thought you just had the hots for your sister, I hope you don't mind if I take some for myself."

Beth took Sam's penis right out of his hand and started stroking it for him. Sam groaned, hoping he could cum before anyone else woke up.

"I need you to get really horny for me," he said. "Can you lick my ass?"

Beth looked up at him deviously. "Ok, just for you."

She kept beating his meat, blowing him for a few seconds to get it nice and wet, and he spread his legs as her mouth licked down his shaft to his balls and still further. He tilted his head back as Beth's sweet tongue danced around his asshole, and finally pressed firm against it. She literally sucked at his asshole, her nose burying into his balls. He loved it, and was surprised more guys didn't talk about having this done. All of his friends would probably think it was gay, but they were missing out.

Beth kept at it like a good girl, until Sam finally grunted and his cock stiffened. Her mouth left his ass and locked onto his dick, sucking the shaft as deep as she could take it as he began spewing hot cum down her throat. He thrust up into her face, holding her head with his hands as he fired away, blissfully into his cousin's eager mouth. Beth swallowed everything, sucking what was left in him. Finally, he relaxed and just stroked her hair while she continued to blow him.

"You're pretty dirty, huh?" he finally said.

Beth withdrew from his dick. "I can get really horny sometimes, and I just crave naughty things."

"I would never even ask a girl to lick my ass, before last night."

Beth smiled. "Well, most people think anal is gross. Did your sister's ass taste gross? Or Lilith's ass?"

Sam shook his head. "No, it just tasted like skin. It was kinda sexy actually."

Beth bent down again and gave Sam's ass a firm, powerful lick, sending shivers up his spine.

"I'm very open-minded," she said, her hot breath on his balls.

Sam sighed contentedly. Beth reached for her t-shirt and covered herself, throwing Lilith's shirt over to her.

"I just can't imagine not wanting to be with you, all of you," Sam said, watching her get dressed. "I mean, how am I ever gonna have a girlfriend when I can fuck Sandy?"

Beth shrugged. "Well, eventually you'll both probably want to see other people. But that doesn't mean you can't fuck. Incest is different than cheating. It's such a powerful secret that you can't tell anyone except the people involved. But if you happen to find a wife that is open to it, maybe even likes it, then that would be a bonus."

"So, you'd fuck me even if you got married?" Sam asked.

Beth thought about it. "I guess so, I mean, I don't see why not. As long as we both wanted it."

Sandy was awake for the tail end of their conversation, stretching underneath her sleeping bag.

"Both wanted what?" she asked.

"Sex," Beth replied. "Sam here thinks you won't be enough for him, and he wants to see me too once in a while."

Sam laughed. "I never said, not enough. It's just fucking hot, what we did. I don't want it to stop."

Sandy put her t-shirt on and crept sexily over to her brother. "Beth may have better tits than me, but I don't want you thinking that I'm giving you up so easily."

Sam grabbed her breasts and squeezed softly through her shirt. "I love your tits. And your ass."

Sandy wanted to be bold and reached down below Sam's dick and meant to touch his asshole to shock him, but found that it was already wet with saliva. She glanced to Beth, who smiled sheepishly.

"You've already been playing," Sandy smiled. "No fair."

"I don't think Sam's gonna be much help if you're horny for dick," Beth said. "But Lil would probably lick you everywhere."

Lilith was snoring soundly in her sleeping bag.

"Later, maybe." Sandy fingered Sam's asshole for a moment, and then threw him his boxers and shirt. "We should plan something fun for today, besides crazy sex."

Sam agreed. "Yeah, let's go out and do something."

"First, breakfast," Beth said. "I'm starving!"

**********

The day was eventful for the whole family, besides all of the sex between the cousins. Sam found it hard to look at his sister or his two cousins without picturing them wrapped around his cock. But they all managed to hide their new relationship from everyone else. Sandy and Lilith were inseparable as usual, and he had to fight to keep his distance from Beth.

But after a nice long dinner, and when all of the adults were exhausted, the kids all made their way down to the basement to spend the rest of the evening. Sam was the last one down there, the others practically racing. He was already hard as a rock by the time he collapsed on the couch. The girls were all in front of the television, but they were obviously just waiting for him.

"I have a fun idea," Beth said.

Everyone intently listened.

"Lil wants to lose her cherry tonight," she said matter-of-factly. Sam blushed a bit, his eyes darting to Lilith. Lilith seemed embarrassed, but smiled back at him.

"I think he's down for that," Sandy said, laughing at her brother's reaction.

"I think Sandy should get Lil ready," Beth continued, "and I'll see to it that this guy's cock is ready."

Sandy threw herself at her cousin, the two of them immediately a frantic mess of kissing and groping. They were naked in less than a minute. Beth hungrily eyed Sam's cock through his boxers, noting that he didn't need any help to get ready. Still, she had been waiting to suck that beautiful penis all day.

Sam remained still, enjoying the show of his older cousin sauntering over to him and kneeling between his legs, her fingernails dragging down his thighs to his knees as she got into position to suck him off. She gently opened the fly of his boxers, letting him spring free into her face. She ran his warm dick along her cheeks and face in a naughty, almost obscene display of horniness. Sam couldn't stifle a groan as her tongue snaked out and caught his head, trailing softly down to his balls where Beth sucked for just a moment, teasing him.

"Lil's pussy is really tight," Beth said quietly so only he could hear, his cock slapping her face. "Do you wanna let one go first?"

Sam only nodded. Beth smiled in gratitude, and began to lovingly suck on his penis. She bobbed gently up and down, her lips and tongue exquisitely working on him. Her hands roamed up and down his thighs, and at times she was able to bury him all the way down her throat until her face was touching his belly. Sam grunted, thrusting just a bit involuntarily. This girl could give head!

Sandy and Lilith were in a frenzy, but Sandy took charge and pinned Lilith down so she could suck her pussy. Holding Lilith's legs apart, Sandy licked at her pink gash over and over, driving her cousin crazy with pleasure. She sucked on Lilith's clit, making pussy juice ooze all over her face. Lilith couldn't hold back her climax, especially when Sandy suddenly tongued down to her asshole and invaded her tight pucker. Lilith's breath escaped her when her orgasm reached its peak, holding her there on top of a cloud so long she almost passed out.

Beth could tell Lilith was already cumming, and she wanted her sister to have this stud soon. She looked up at Sam and met his gaze.

"Can you cum right now?" she asked.

Sam nodded.

Beth worked his cock with her hand, spreading her saliva and stroking him harder, squeezing and twisting her grip around his shaft. Sam moaned loudly, feeling the cum rise in his loins. He expected Beth to let him cum all over himself, or maybe suck him while he shot down her throat. Instead, she opened her mouth wide and tilted her head back slightly, letting his sperm shoot out all over her face. Sam had never cum on a girl's face before, but he loved it! Beth stroked him slower, coaxing out each blast of semen as it tagged her forehead, then her cheek, then her chin. Drips of hot white load dribbled into her mouth as she finished masturbating him.

"God, that was so good!" Sam exclaimed.

Beth just smiled, lovingly kissing his cock head and licking the sperm from the tip. "Ready to fuck my little sister?"

He stood, his cock still hard as a rock. Sandy let Lilith go from under her, and instead made her way to Beth. To Beth's surprise, and delight, Sandy began licking her brother's cum from her face, sucking it all down and swallowing it. The filthy act ended with the two of them kissing violently, sucking at each others' tongues and mouths.

Sam let Lilith get into position. She apparently wanted doggie style, as she propped herself up on her hands and knees, and looked back at him with pleading anticipation in her eyes.

"You can finger my ass if you want," she said, "I really like that."

Sam wet his fingers in his mouth and touched her pussy, splitting it open and rubbing her hole. Lilith groaned, her legs trembling already. She was going to lose her virginity to her hot cousin! She was so excited.

Sam bent forward to give Lilith's asshole a lick and a kiss, making her shiver. Then he positioned his thick cock at her entrance, and very gently eased into her. Apparently she and Beth must have played around a lot, because her pussy didn't tense up like all the virgins other he'd fucked. She was incredibly tight, but there was no resistance to his invasion. His dick slid right up into her, tearing through whatever virginity she had once possessed and claiming her first pussy fuck for himself. Lilith bit her lip, actually getting off on the slight discomfort of her first penis. The act was so raw, so brutal, she felt like an animal in heat.

Fortunately for him, Sam felt like he could last all night now. Beth had the right idea, getting him off first. Lilith's tight little hole accepted him and responded to him wonderfully. They fucked and fucked, changing positions and returning to doggie style so he could stick his finger in her butt while he pounded away at her tight little body. The two of them were too caught up in their sex to really notice Sandy and Beth watching them from mere feet away, fingering their own pussies while they watched their siblings and cousins performing for them.

Finally, after Lilith had cum more times than she could count, Sam felt the stirrings of his cum again. He had never cum in a virgin's pussy without a condom on. This would be a first, if she would let him.

"I'm on the pill," Lilith said, reading his mind and feeling his cock throb and expand.

Sam nodded, and relentlessly thrust himself into until he felt the explosion starting to build. In the back of his mind, he heard his sister cry out in orgasm, followed quickly by Beth. He squeezed his eyes shut and let his cock spew endless bursts of cum into Lilith. The two of them groaned deeply, their bodies in perfect sync. Sam had never had a better orgasm, except maybe in his sister that first time. He helplessly twitched and ground his hips into Lilith, pouring out load after load of his semen into her young little pussy hole. He loved that they were being watched too. He was surprised how much that got him off.

"Oh god," Lilith said, pulling away from him finally. She laid on the floor, panting. "My pussy is so sore, but I love it!"

Beth crawled over to her sister and kissed her gently on the face. Sandy hugged her brother from behind, squeezing her arms around his chest.

"That was so beautiful," she said. She could see his cock dripping below her, his erection weakening just a bit after all the energy he had spent.

Sam was catching his breath, but he had to admit he had never felt this tired and satisfied at the same time.

"Now we're all experienced fuckers," Beth said, laughing. "That means new rules."

Sam frowned. "Rules?"

Beth cuddled up next to Lilith, who seemed to be falling asleep. "Yep, I think it would make things more interesting, and fun."

"Like what?" Sandy asked.

"Like, since Sam's got the only cock, that makes things a bit unfair for some of us. So I propose that before he fucks any of us twice, he has to fuck all three of us. So no one gets more cock than anyone else."

Sam laughed, amused by her so-called rule. "Hey, I won't complain about that."

Sandy frowned, making a sad face. "So I have to wait three turns from my last time to get fucked?"

"You get him all you want after we leave," Beth replied. "You're lucky we're letting you have him at all right now."

Sandy smiled, realizing her cousin was right. "Fine, I suppose you're right."

"And..." Beth said, adding suspense. "...if you're all up for it, I think that each time he fucks us, he should have to stick it in our pussy and ass before he cums."

"Wow, you're dirty!" Sandy said. "We haven't even seen you take it up the ass yet."

"I know, and I'm getting rather jealous. Thus, the new rule."

Lilith was out, snoring softly next to her sister's warm body. Sam's cock had sprung to new life listening to these naughty rules and thinking about getting ass every time he fucked one of these gorgeous babes.

"I get to make a rule, then." He surprised Beth and Sandy with his boldness. "Whoever I fuck, a different person has to suck my dick. Whenever I want it sucked, before or after, or in the middle even."

Beth licked her lips. "I'd like to suck on that big dick right now."

Sandy waved her finger, smiling. "Oh no, it's my turn to suck him. You already made him cum on your face."

Beth shrugged. "Fine. Maybe I'll just rape Lil while she sleeps."

Sam stretched, feeling the exhaustion start to spread over him. But still, he couldn't resist as his sister moved around to the front of him and pushed him back on to the couch. Their eyes meeting, Sandy lovingly invaded her brother's butt with her finger while her mouth closed around his cock, tasting her cousin on him. This was going to be a really fun night...
