He rolled his eyes as they drove under a lamppost. "I saw that!" a voice shouted from the back. Britt, his sister's friend from college, met his eyes in the rear-view mirror and stuck her tongue out at him. Sam rolled his eyes again, exaggerating the movement. Britt confused Sam. She seemed like a perfectly nice girl, but she was just so different than his quiet, introverted sister. Britt seemed to be the quintessential sorority girl type that he'd been very familiar with during his undergrad. "We almost there yet, grandma?" "About an hour," Chloe piped up from the back seat. "Should be forty minutes," grumbled Britt. "It's snowing and it's dark," was all Sam said by way of explanation, to which Britt shrugged and dropped the matter. Fifty minutes later they pulled into the driveway of their family cabin, Britt quickly shoving her door open and scrambling out. "Fuck! It's cold out here!" she yelped. The frigid air rolled into the car, making Sam and Chloe shiver. They joined Britt and hurried to the front door, fumbling with the lock and pushing in. "It's just as cold in here," Britt complained. "Master bedroom," Chloe pointed, and began to walk, rubbing her hands together. When Sam and Britt entered the room she had already opened the fireplace flue and was in the process of lighting some kindling. "Bathroom?" Britt asked. Sam pointed, then went to the closet in the hallway and brought out a large quilt. When he got back to the room a small fire was going in the fireplace, his sister kneeling in front of it. She looked back at him and smiled. "It's been too long." Sam knelt by her and nodded, wrapping the blanket around both of them. They had come here every winter as kids, but their parents' divorce, along with Sam going off to college, meant they hadn't been for six years. Now, done with his master's program in France, Chloe a sophomore in college, they were finally back. Britt exited the bathroom, clutching her arms and shivering. "Come over and warm up," Chloe called over. She joined them and they all huddled together, warming up slowly as the fire heated the room, recalling all the years they'd done this as a family as soon as they arrived. Chloe yawned. "Bedtime?" Sam asked, looking down. Chloe nodded, and they got up. "What are we doing about rooms?" Britt asked. "Oh. We usually just sleep here the first night. But I could sleep somewhere else if you-" "No, that's fine!" Britt assured him, perhaps a bit too quickly. "But my pyjamas are in the car..." Chloe went to the drawers on the wall and pulled out some large, oversized flannel. "Got you covered," she said, smiling. She took some herself, throwing some to Sam. "We'd always just come right here and collapse the first night." She went to the bathroom to change. "Cute," said Britt, holding up the brown flannel. Then she looked at Sam and smirked. "Mind if I change in here?" Sam suddenly thought back to the conversation he'd had with Chloe before they'd left. "She's probably gonna try to sleep with you, just so you know." "What?" Sam had asked, taken off guard. Chloe shrugged. "Just a warning. I can tell when she's planning something like this." Her face was slightly red, and Sam wondered if she was warning him off. Would it be weird if he slept with her friend? Would Chloe be mad? "Should I tell her no if she tries?" he asked uncertainly. He certainly wouldn't mind sharing his bed with Britt. He'd caught a few glimpses of her ample cleavage before they'd left, and couldn't help but look at her leggings-clad ass whenever she walked by. "No!" she said, strangely forcefully. "I don't mind, seriously. You can do her if you want." Sam had smiled, raising an eyebrow. "I can do her?" he teased. Chloe blushed, hitting him softly on the arm, but smiled slightly. Now, not half an hour after getting to the cabin, Britt reached down to pull her shirt and sweater off in one movement. Her breasts were held by a tan bra, and Sam's eyes were drawn downwards immediately to drink in the sight. Britt turned her back to Sam then, pulling off her leggings to reveal her ass in a pink thong. Sam had trouble keeping himself from reaching out and grabbing a handful, his cock stiffening in his jeans. She reached behind her to unhook her bra, letting it fall to the ground with her leggings, then bent over to grab the flannel she'd thrown on the ground. Her ass cheeks spread slightly, causing Sam's cock to twitch, and the bathroom door opened. Chloe's eyes widened slightly as she took in the scene, darting quickly between Sam and Britt. Then Britt pulled the shirt around her shoulders and closed the front, its hem hanging down to her thighs, ending the show. Sam coughed, then walked over to the bathroom to change, his cock painfully erect. He heard Chloe whisper something as he closed the door, and Britt laugh. He did his best to calm down before he left the bathroom, and he was mostly in control as he got into bed with his sister and Britt. The girls were snuggled together, turned away from him as he slid under the covers, Chloe closer to him. He joined them, wrapping an arm around his sister's waist, and quickly fell asleep. **** Sam woke up shivering on his back with a small corner of the blanket. Chloe and Britt were huddled together, still asleep, the blankets bunched around them. Sam pulled on the comforter, and Chloe groaned. "It's so cold." "Yeah, so gimme some blanket." "We forgot to turn the furnace on," Chloe grumbled. "Could you go do it?" Sam sighed, rolling out of the bed and shuffling over to the bathroom to relieve himself before heading downstairs. As he got the furnace going he thought about Britt. He'd never had a girl he didn't know be so brazen about undressing in front of him. His cock once again hardened as he thought of her almost naked, ass spread in front of him, and put his cold hands down his pants to grasp his erection. He simply held his penis for a minute, hands warming up slightly, then started to stroke absently. The memory of Britt undressing replayed itself over and over again in his mind as he masturbated, imagining himself taking her right there. Soon he realized he was about to cum in his pants, and stopped stroking. He was hit by a wave of exhaustion, and decided to finish himself off later. Chloe jumped a bit when he reentered the room, her arms moving a bit somewhere under the covers. Britt sighed and shifted slightly. Sam took his place behind Chloe, taking back some of the blanket, and quickly dozed off again. When he woke again it was to a warm and empty room. He found the girls in the kitchen, fully dressed and shivering. "We got the food and clothes from the car," Chloe said. "Awesome." Sam started to gather what he'd need for breakfast and got cooking as Britt and Chloe went to change. They only came out of the master bedroom when the food was almost ready, bacon sizzling on the frying pan, eggs cooking in their grease. Sam spent the day relaxing with a book in the living room, and Britt alternated between teasing him and spending time with Chloe in other parts of the house. She would come in every hour or so and bend over a bag to search for something, revealing her cleavage down her low cut v-neck, or her pert butt stretching her leggings. By the third occurrence Sam didn't even pretend to look away, and she'd end each one with a smirk, meeting his eyes. That night he took the room he and Chloe had shared as kids, while she and Britt took the master bedroom. The door closed, he stripped and got into bed naked. He was just drifting off when the door opened. "Wha-" he began, then felt a body slip into bed beside him, and a hand found his cock. Britt was warm, and after the first moment of shock and confusion he relaxed. She went down and took him in her mouth, expertly teasing his cock erect, his hands grasping fistfuls of her hair. She wasted no time once he was hard, pushing him on his back and straddling him, aiming his cock, and before he knew it he was inside of her. She was already wet, and her saliva allowed him to slide in easily. She rode him hard and fast, completely dictating the pace, and soon he stopped trying and let her at it, enjoying the sensation of her cunt around him. His hands grasped everywhere he'd been fantasizing about, focusing mostly on her luscious, soft breasts with their fat nipples, pinching and pulling. After only five minutes he was ready to cum. He tried to warn her, but she ignored him, so he just allowed himself to be taken up in orgasmic bliss, thrusting up as his cock spewed thick spurts of semen into her pussy. She slowed, stopped, then stood and left without saying a word, cum dripping down her leg. **** "Truth or dare?" "Truth, I guess." Sam didn't know why they were playing this game. But they were all pleasantly buzzed, having started drinking in the early evening and continuing into the night. He'd been worried that things would be awkward, with Britt and with his sister. But Chloe had just given him a strange smile when she saw him in the morning, and Britt had teased him mercilessly, taking every opportunity to rub her body against his, squirming in his lap whenever he sat. They now sat in a circle in front of the fireplace in the master bedroom, drinks by their sides, playing this silly game. They spent an hour getting steadily drunker and steadily more risque. But Sam wasn't sure how far he should take it with Chloe right there. "You ever fucked a girl?" he asked Britt. She was quiet for a moment, a small smile on her face, before answering. "Yes." Sam raised his eyebrows. He wouldn't have pegged Britt as the type to experiment with that. "How many times?" "Not your turn," she countered. "Chloe. You ever slept with a girl?" Chloe's head jerked to face Britt as Sam turned to her. He was shocked to see her face turn bright red, mouth open. She shrunk into herself a bit. "Really?" Sam asked. She gave a small nod. "When did that happen?" Britt rolled her eyes. "Still not your turn, bucko." Sam sighed. "Truth me then." Britt thought for a moment. She and Sam were doing most of the work, Chloe just answering questions or doing their dares. "Group truth!" she decided, meaning everyone had to answer. "What are your kinks and fetishes?" "You have to go first then," Sam said. "Oh yeah. Hmm. I really like to be spanked, and I've always liked the idea of being tied up." She shrugged. "Stuff like that. Chloe?" Sam didn't expect her to say anything. So he was once again surprised when she took a deep breath, closed her eyes and started to talk. "Um, I like feet, I guess, and also anal. I've never had anal sex but I finger myself there sometimes and I really like it in porn. And guys cumming, I like to watch that, especially on girls. Sleeping girls, too. But my biggest one is probably watching people get naked and have sex, especially if they don't know I'm watching. That's so hot." She opened her eyes. Sam was staring at her, mouth open. Britt just grinned, but didn't seem at all surprised. It seemed that she'd forgotten that her brother was sitting to her left, and her hand went to her mouth. She blushed again. "Your turn," she said quietly. "Wow. Mine is panties." He'd actually never told anyone that. He'd always wanted to tell his girlfriends, but for some reason had always been embarrassed. But the combination of drink and his sister's laundry list of kinks got him to spill it, though his heart still beat quickly in his chest having admitted it. "Ooh!" Britt seemed happy about this. "Panty party! Everyone in your underwear!" Chloe and Sam looked at her strangely. "What?" "C'mon, it'll be fun!" She jumped up, steadying herself on the mantel as she nearly fell back down. The other two watched with open mouths as she stripped off her leggings, revealing a small, navy G-string. She reached down and, to Sam's surprise, got Chloe to stand up. She glanced at Sam with a worried expression, then shrugged. He watched as she unbuttoned and unzipped her jeans, then began to peel them off. She wore a small pair of plain, light green panties, much more innocent than Britt's sexy pair. They both sat down, cross-legged. "You too, dude." Sam looked up in surprise. "Oh. Sure." He stood up, unsteady as Britt was, and took off his jeans and sat back down. His eyes were drawn to the panties in front of him, and he felt himself getting hard immediately. He shifted, trying to hide it in the folds of his boxers. "Dare," Britt said. Sam looked up, realizing it was her turn. "Take your shirt off," said Chloe immediately. Sam shook his head, and decided to stop being surprised by his sister. Britt smiled and took it off in a smooth movement to reveal a red bra and threw the shirt to Chloe, who gave a small smile. Sam's cock hardened completely with Britt and his sister in their various states of undress in front of him. He tried to ignore Chloe's nearly-naked bottom half, but found it strangely difficult in his drunken state, often catching his gaze turning to her crotch. "Dare," said Chloe. Sam was disappointed. There were so many questions he had for Chloe. "Don't wear pants for the rest of the time here," Britt said quickly. Chloe nodded, then looked at Sam. "Truth." "Whose panties do you like more?" Britt asked. The question caught Sam off guard, especially because of the answer. He paused, then looked away, embarrassed. Britt was more perceptive than he'd thought. "Chloe's," he said eventually. "I just like the simpler ones," he explained, looking at her guiltily. Chloe shrugged, then stood up. "I need to pee," she said, making her way carefully to the bathroom and shutting the door. "Dare," said Britt. He looked at her, then made the easy decision with his sister gone. "Lose the bra." She nodded, reaching back and unhooking the straps, letting it fall. He'd felt them yesterday, but it had been too dark to see them. He admired them, full and firm, with hard, brown nipples. "Truth or dare?" "Dare." "Get naked." Sam quickly complied, tearing his shirt and boxers off, erection freed. Britt leaned forwards and grasped his cock lightly, then reached down to lick its head. Soon she was slowly pumping and sucking, a stark contrast to last night's quick, frenzied blowjob. Sam's hands explored her body, grabbing handfuls of her breasts, pushing them together, then reaching down her back. He forced more of himself into her, causing her to gag slightly as she accomodated him, and slapped an ass cheek. She moaned around his cock, drool trailing down to his balls. He lifted Britt from his cock and directed her to the bed, where he flipped her on her front over the side of the bed and pulled her G-string to one side. He placed his cock's head at her slit and moved his hips forward, sinking into her slowly. She moaned as he filled her, not stopping until he was completely inside her. Then he gave her another sharp spank. He began to fuck her, starting slowly and gradually building up speed. Her tight lips gripped him wonderfully, the navy fabric of her panties pressed against the side of his cock. Soon Britt was moaning constantly, and he felt her pussy tighten and contract around his cock. This brought him over the edge, his cock shooting into her for the second time in as many nights, grunting as her cunt milked him. He slowly took his cock from her pussy, his cum spilling from her to drip down her leg and staining her G-string. She turned, and Sam suddenly remembered - Chloe. He turned to the bathroom door and saw her standing there, in her T-shirt and panties. She walked over and sat on the bed next to Britt, wrapping an arm around her naked shoulders. Sam was hit by a sudden realization, and Chloe leaned over and kissed Britt on the mouth. "Oh," said Sam, feeling foolish. He saw Chloe smile through the kiss, but otherwise they ignored him. He made to leave, trying to sort through this revelation, when he heard Chloe talk. "You can sleep in here with us if you want." Sam did want that. He lay back on the bed with Britt and Chloe, who didn't continue their makeout session. Making themselves comfortable, Britt in between the two siblings, all three drifted quickly to sleep. **** Sam woke up to movement and an achingly full bladder. He saw the bathroom door close and swore to himself as he waited for Chloe to finish, Britt sleeping peacefully next to him under the covers. He got up to stand outside the door, a bit dizzy. It seemed that he was still slightly drunk. Chloe smiled at him when she came out and he hurried to the toilet. He realized he was still naked, and had just walked by his sister. The thought sent an odd shiver through his body. Bladder empty, he washed his hands and left the bathroom to see Chloe standing at the large windows alongside one wall of the room. She still wore her green panties and a T-shirt, and Sam found that he couldn't look away, her small, pert butt and the gap between her thighs drawing his complete attention. He slowly walked up behind her, his cock as hard as it had ever been. "I think there's been a cold front," she said. He grunted absently, then realized she was probably right. It was quite cold by the window, though a cold morning sun shone through. He stepped right behind her, arms wrapping around her waist. He looked down. She wore a very thin white T-shirt, so thin he could see the goosebumps raised on her skin through it. And her hard nipples poked through, the bra she'd worn last night inexplicably gone this morning. He moved his hands under the shirt. Her skin was cool as he drew his hand upwards, reaching her small breasts and cupping one in each hand. They were both breathing heavily. Sam had no idea why he had done this, but he continued to massage her tits as she turned to look up at him, his cock pressed against her back. She raised her head and he bent down to kiss her, mouth pressed hard against hers, her tongue invading his mouth. She moaned softly into him. Then they both broke away, and the moment was over. What had they just done? They looked away, Sam's hands leaving her chest as they stepped apart. Then they both moved slowly back to the bed, where Britt had slept through the entire thing. They lay back down next to each other under the covers, neither saying anything. Sam reached down to grasp his painfully erect cock, squeezing and stroking gently. He noticed movement under the covers around Chloe's midsection, and knew she was feeling just as horny, and probably just as confused, as he was. They both jumped and quickly stopped as they heard Britt shift. She pushed herself up to a sitting position, then stretched and yawned. "Morning." Chloe pushed herself up to sit beside her, kissing her on the cheek, then got out of bed and rummaged through her bag, fishing out a shirt and another pair of panties. With her back partially turned to them, she dropped her panties to the ground and stepped into her new ones. Sam's eyes were glued to the sight, and he continued to watch as she replaced her shirt. Suddenly he felt a hand around his cock, and the covers thrown from his legs. He turned to see Britt watching him with raised eyebrows. "Hey Chloe, pass those panties." Chloe looked around, looking surprised when she saw Britt holding Sam's cock. She picked up the green cotton panties and threw them over to Britt. She tugged his cock, guiding him to a kneeling position facing his sister, then knelt behind him. Her breasts pressed against his back as she reached around him and started to jerk him off. The panties were brought to his face, and he found himself inhaling a soft, musky scent. His eyes widened, and he saw Chloe's do the same. Family Cabin "Hmm, you like that?" Britt murmured in his ear as her hand worked at his cock. Then she brought the panties down, rubbing the slightly damp crotch on his cock's head. "Oh my god," he gasped. This was incredible, so much more intense than a regular handjob. He felt like he might cum at any second, the feeling building as she stroked. After a couple more minutes he gasped "Cumming." Britt spread the panties in front of his cock as the first thick white jet of cum shot forcefully into the crotch. Britt kept stroking the the biggest load of his life out, his sister watching on. He sagged, panting, then looked up at Chloe. Her gaze was fixed to his cock, then she glanced up and met his eyes. Then, she walked tentatively forward and took the soaked panties from Britt's hands. **** Exhausted and starving, they got dressed and ate breakfast in the kitchen. Chloe kept to her dare from the previous night, only wearing thin gray panties and a shirt. She shivered slightly in the cold kitchen, the cold outside permeating the house, and once they'd finished eating she snuggled up with a blanket on the couch alongside Britt. Sam sat in the armchair across from them. "So when did this start?" he asked. "When your sister started perving on me." "Hey," Chloe protested weakly. "Caught you looking down her shirt?" Sam teased. "Oh, no, way worse than that." Britt grinned. "You wanna tell him, or should I?" "You're just gonna make it sound bad." "Okay, tell it the innocent way then." Chloe blushed. "We lived across the street from each other and I could see in her window at night when she turned the lights on. I saw her changing a few times but she saw me watching and came over. For some reason she wasn't mad and somehow we ended up hanging out and then... got together," she finished. "Well, yeah, if you count seeing me changing a few times as waiting with a pair of binoculars during times you knew I'd be getting ready to go out, for three months, yeah you saw me a couple times." Sam raised his eyebrows. "Wow Chloe. Never pegged you for that type." She blushed, but didn't actually look too embarrassed. "I also let her see me fucking a couple guys." Sam saw movement under the blankets, and Chloe closed her eyes. "Mhmm," she murmured. "How'd you figure out she was spying?" "There were a couple of times early on where she left lights on in her apartment. But later I could tell because whenever I got home all the lights in her apartment would go out." Chloe sighed, hips shifting. Sam wished he could see what was going on under that blanket. "She was so terrified when I went over and asked if she was enjoying the show. Then I asked her if she wanted to get coffee, and it all went from there." Chloe had stopped listening, squirming as Britt continued whatever she was doing under the blanket. Sam's hands were in his loose pyjama pants, past the point of being confused that his sister could get him this horny. They stopped talking as Chloe continued to moan softly. After five minutes the moans got louder, then suddenly stopped. Britt's hands no longer moving, Chloe's body began to shake, then tensed as she cried out once. Then she relaxed, a sleepy, satisfied smile on her face. Sam watched that smile as he slowly jerked his cock for the next five minutes. Britt slowly extricated herself from his sister, laying her on her back, feet hanging over the edge of the couch. Chloe continued to sleep, the blanket falling away to reveal her legs and gray cotton panties. Britt walked over to him and whispered, "Do you want to cum on her?" Sam looked over uncertainly. There was nothing that he wanted more at that moment. But she was still his sister. Despite the fact that he'd cum in her panties as he watched her this morning, despite that he'd kissed her just before that, this would undeniably be crossing a different boundary. "I dunno. I mean, she's asleep..." "I promise you, she wouldn't mind. She'd find it hot," Britt urged him. She had said she was into sleep stuff, Sam recalled. He could feel himself justifying it to himself, his cock hard as it had been this morning. He nodded slowly. "Okay, great. Wait here." Sam got up, walking to stand over his sister. He looked down at her, pretty face completely relaxed, wavy brown hair spread around her head and shoulders. He looked down at the gray panties clutching her hips, slightly damp from Britt's earlier attention. He leaned forwards and breathed in, her wonderful scent causing his cock to twitch. Britt came back into the room carrying a camera and a pair of scissors. "What are those for?" "She'll want to see," she told him, then knelt beside her and began to cut up the front of Chloe's T-shirt. "Wait-" Sam began to whisper, but Britt had already made the first cut. He watched nervously as she completed the cut and pulled the two sides of the ruined shirt apart, revealing his sister's small breasts, pink nipples puckered due to the cold. Feeling her breasts this morning seemed a world away, and the sight of her revealed to him felt no less taboo than it had then. Britt stepped back, and Sam knew that he was going to do this. He dropped the pants, naked erection pointing towards the ceiling. Standing between her slightly spread legs, he began to stroke. His entire body trembled uncontrollably. Two days ago he would have never imagined thinking about his sister like this, would have probably been disgusted by the thought. And now he knew that the only orgasm he'd ever had that would come close to rivalling the one he was about to have was the one he'd shot earlier into Chloe's panties. The orgasm built quickly and ripped through him, the first ropes of cum flying up his sister's body to land on her breasts. More followed onto her stomach, the last dripping down onto her underwear. Panting, Sam lowered himself to wipe his cock on the panties, shuddering as two last unexpected streams of semen left his cock when it pressed against her soft lips through the fabric. "Oh." He looked up to see Chloe looking down sleepily. He felt scared, suddenly. He shouldn't have done this. But then she smiled. "Was it good?" she asked. He nodded. Her hand trailed down her sticky body, ending at her wet panties. "You're gonna ruin all my underwear," she said, giggling. "That's the idea." The words were out of his mouth before thinking. Chloe laughed. "I'm glad one of us has a plan. What's next?" "Probably a shower. And after that, we'll have to see." **** After they'd washed the sweat and sex from their bodies, they actually managed to keep their hands off each other for a few hours, playing games and watching movies on the ancient CRT TV in the bedroom. Chloe still didn't wear pants, exchanging her soiled gray panties for a black pair with frilly edges. They didn't last that long, though. As it turned dark they got back into the bed, Chloe watching as Sam penetrated her girlfriend, slowly fucking her from behind. After the excitement of the day, he took his time, penetrating her deeply with each thrust. Chloe sat right beside Sam during, occasionally grabbing Britt's ass and running her hands over her body. Then a finger found its way between her ass cheeks to rub Britt's asshole. Sam watched hungrily as his sister carefully eased a knuckle into Britt, his strokes slowing, Britt moaning into a pillow. "When you're about to cum, pull out and don't touch it," Chloe whispered in his ear. He looked at her confused, but nodded. Chloe removed her hands from Britt's body and knelt back on her ankles, simply watching. Sam got dangerously close to cumming but pulled out in time, cock pulsing. Then Chloe's hand reached out and grabbed his erection, forcing him over the edge as she stroked it, cum flying where she aimed it at Britt's asshole and pussy. "Oh, fuck." He saw bright spots in his vision, his sister not slowing down until his cock had ceased shooting. Breathing heavily, he looked down at her. She looked at him nervously, releasing his cock suddenly. He pulled her towards him to reassure her that he was okay with what she'd done, remembering how he'd felt when she woke up to him between her legs. Britt's hand reached back to play with her cummy pussy, then turned around. Sam wasn't sure whether she realized what had happened, but she didn't mention it as she cleaned herself up with her discarded panties. "Wow," she said, looking down. "Lot of cum for number three. Do you always cum this much?" Sam shook his head. "Not usually." He was pretty sure he wouldn't have cum nearly as much as he had any of the times today had his sister not been his main focus. He all but collapsed soon after, swallowed quickly by sleep. **** Sam felt movement in the bed next to him, opening his eyes to see Britt on her back. Looking down he saw Chloe between her legs, butt poking into the air, mouth on Britt's cunt. He watched in awe as his sister ate Britt out slowly, making her squirm and moan softly. There was no urgency to Chloe's movements, teasing Britt's lips with her tongue, the occasional finger pushing into her momentarily. Eventually Britt's hands buried themselves in Chloe's hair, pulling her closer, urging her to speed up. Chloe complied, a thumb slipping easily into Britt as her tongue licked around her clit. Moving with a steady, even tempo, Chloe brought Britt to a crashing orgasm, crying out in time with the movement of Chloe's hand. Her hands let go where she had been grasping Chloe's hair tightly, falling to her side as she gave a contented sigh. Chloe pulled herself from Britt, crawling up to kiss her lovingly on the lips, sharing with Britt the taste of her juices. Sam continued to watch in silence. He'd debated looking away, knowing that this wasn't for him, but the sight was too erotic to ignore. Eventually they stilled, Chloe laying in Britt's embrace with her back to Sam. He went to the bathroom, and when he returned they were both on their backs. Chloe turned to him, putting a finger to her lips. Sam nodded, noting Britt's closed eyes and deep breathing, moving to sit next to his sister. "Did you see that?" she whispered, eyes going to his erection. "Yeah. Sorry." "No, it's fine. It's just..." she gestured vaguely to Britt's sleeping form. "She can't help." Sam nodded. He'd realized as well that every time anything had happened so far, Britt had been the focus or had urged it to happen in some way. Now, with her asleep, doing anything would feel strangely different, less excusable somehow. It wouldn't be in the heat of the moment, but something they consciously chose to do. He was so horny though, and didn't feel at all like he'd cum three times yesterday. "I could take care of it myself," he suggested. She nodded tentatively. "Yeah. You probably should. I'll let you do that then." She turned away and lay down on her front. Sam felt a pang of something - he'd hoped that they would figure out an excuse to do something together. It was so strange, going from last night, Chloe finishing him off, to this morning where he couldn't even masturbate in front of her. Then she shifted, spreading her legs slightly and raising her ass a few inches in the air. Sam felt a thrill go through him. Without a word, he moved behind her, between her legs, and started to masturbate. Neither said anything, but soon Chloe had raised herself to her knees, head in her arms, ass sticking up completely, covered by her black panties. He shot his load without warning, aiming at her covered pussy lips. Next he hit her ass, and then the back of her legs. Then without thinking he grasped her hips and rubbed his cock on her panties, between her cheeks, spreading his cum with the underside of his dick as he thrust, the last remnants of his orgasm dribbling out onto Chloe's back. They were still for a moment, then Sam realized what he was doing and quickly let go, moving back. "Oh," said Chloe. "Could you grab me another pair from my bag?" Sam walked over and rummaged through it. There were only two pairs of panties left, one pink, one white. As Chloe watched, Sam wrapped the pink ones around his cock and wiped his cum from it, squeezing the last few drops out, then threw the white ones over to her. "Last pair." She showered first, coming out having changed her black panties for the white ones. He found the black ones on the floor of the bathroom, cum side up in front of the shower. When he reentered the bedroom, Chloe was pouting, causing Britt to laugh. "I don't see how you could still be horny. You must be a superhuman." "What's up?" asked Sam. "She says she's too worn out to do anything sexy today," Chloe told him. Britt looked at Sam. "There's no way you have any energy left," she exclaimed. Sam shrugged, and she rolled her eyes. "Superhumans, I say. You'll just have to entertain each other, then." At those words, Sam and Chloe glanced at each other, eyes widening slightly. Britt didn't see as she headed to the bathroom, but once inside she called out, "As you've already started to do, I see." She stuck to her word, rebuffing all attempts by both of them to fool around. But they kept trying, feeling that they needed her influence, especially given that she was awake. "Oh my god!" Britt cried out eventually. She was on the couch next to Chloe, who was rubbing her thigh up and down while Sam sat across from them in the armchair. She stood up, beckoning Sam and Chloe to follow her. She led them to their old bedroom, the one they'd used as children. She directed Chloe to get on all fours across it, and had Sam stand behind her. She yanked down Sam's pants. Then, she grasped Chloe's panties at the hips and tore them down her thighs. Chloe gasped, and Sam's breath caught. This entire week, he had not seen Chloe's pussy once. Her thin, pink lips were completely devoid of any hair, parting to reveal her tight hole. Britt pointed. "Touch." Slowly, Sam reached out and grasped a cheek, thumb running gently over her wet pussy. "Now, calm yourselves down, for Christ's sake." With that she left the room, shutting the door behind her. **** They spent an hour simply exploring each others' bodies, hands and mouths glancing over every inch they could touch. Sam inhaled her scent, bit down softly in a hundred places. They didn't focus on their genitals, but neither did they avoid them. Chloe's hands and tongue brushed his chest, his stomach, his painful erection, while his hands ran down her back, slipping down her ass and legs. Finally he slipped a finger inside her waiting pussy, sliding easily in. She lay back as he fingered her, then reached down to stroke him. They let loose, Chloe's grip tightening, speeding up as Sam put his thumb to her clit and pressed down. Sam stepped back, pulling Chloe to the edge of the bed, pushing her legs back and kneeling in front of her to put his face between her legs. He licked her pussy aggressively, pushing his tongue inside her, tasting her hot juices as he slipped his middle finger into her. Soon she began to buck, thighs squeezing his head as his tongue pressed hard against her clit. She turned on her back, head over the edge of the bed, and he slipped into her mouth. Her lips and tongue circled his head, completely coating it with saliva before he slowly thrust into her. She couldn't deep-throat him, but her enthusiastic tongue was incredible as he thrust half his length in and out of her mouth, his hands grasping her breasts. He pulled from her suddenly, and her hand flew to grasp him below the head, jerking thick ropes of cum onto her chest and neck, the last few drops eventually dripping into her mouth. He bent down and kissed her tenderly, and she returned it, her tongue entering his mouth as her hands ran through the cum covering her body. "Are you calmed down?" she asked eventually. "No," he said, grinning down at her. "Neither am I." "I'm a bit starving, though." "Oh, yeah, me too," Chloe agreed. Chloe looked around, then stood up, cum dripping down her body to her legs. She opened the drawer next to her bed and fished out an old T-shirt to wipe herself off with. Then they went to the kitchen, sitting across from each other as they ate. Britt popped in five minutes later. "You guys done?" They jumped, turning to her, and Britt looked down to see Chloe's foot between Sam's legs, cock between her toes, having rejuvenated his erection. She sighed, then left the room shaking her head. Her foot there was an odd sensation, though not unwelcome. Soon they were back in the bedroom. Sam lay back on the bed, Chloe standing next to it. "C'mere," he said. She looked down questioningly, then climbed to kneel next to him. He grabbed her leg and lifted it over his body, making her yelp in surprise as she knelt over him. He looked up, a gorgeous view of her pussy from below, and pulled her down by her hips, making her sit on his face. She yelped again in surprise, then louder as she felt his tongue, indiscriminately licking every inch of her pussy. She soon matched his rhythm, grinding down into him, her asshole at his nose. Suddenly she shifted forward, and his tongue was on the puckered hole, her hips moving as he stopped momentarily in surprise. Then he returned enthusiastically, her moans becoming deeper, more primal. Suddenly she lifted off of him, getting on her hands and knees. She looked back desperately. "Sam, I need this," she panted. He quickly pushed himself up. Barely hesitating, he positioned himself behind her, rubbing his cock against her pussy, wet with his saliva and her fluid. She pushed back, his head disappearing into her. Then he leaned forward to bury himself in her completely. "Aah..." She shook as he bottomed out inside of her, cumming around his cock. He held himself there as she finished, then slowly began to fuck his sister. He lost track of time. He didn't know how he lasted longer than a minute, but they continued to fuck for what felt like ages. He stayed in control, moving her body to suit his desires. Finally, as he fucked his sister at the edge of the bed, crossing her legs in front of her, he lost control. His balls tightened, then he began to spill inside of her, letting go of her legs. She parted them and looked up at him, his hands on either side of her to keep from falling over as he held his twitching cock in her. Slowly, he pulled out of her, cum spilling onto the floor as his cock left her. He lay back next to her, legs over the edge of the bed. Her hand found his, fingers twining together. They lay there peacefully, and Sam dozed, not quite asleep, until he felt something soft at his cock. He glanced down to see the white panties Chloe had worn that morning wrapped around him. "You were still hard," she said when he looked at her oddly. He nodded, closing his eyes again, letting Chloe bring him to one last, pulsing orgasm into her panties. **** "We're calm now," Chloe said, stepping softly into the master bedroom, where Britt lay reading a book. She looked up, raising her eyebrows. "Well done. It only took you an entire day." The siblings looked at each other sheepishly. "Well we did have a long nap," Chloe said. "Which would explain the silence, I guess. Aren't you supposed to be wearing panties?" Chloe jerked her head in Sam's direction. "He ruined them all." "What are you gonna do for the next two days?" "I dunno, I guess I'll have to find some other way of keeping modest," Chloe said drily as she climbed into the bed, Sam following. "Touche." Sam listened with half an ear as they continued to banter, but soon dozed off, still exhausted from the day. **** Chloe kissed Britt hungrily, face turned, lips pressed tightly against the other girl's. Sam knelt behind them, watching them make out, their pussies presented to him. Eventually he shuffled up behind them, lifting Britt slightly by her hips, placing his cock at her entrance. He easily slid into her, his torso pressing his sister's body down into Britt's. Family Cabin Chloe moved up to sit on Britt's face, Sam's position making it too awkward to continue making out with her. He watched as she ground her pussy into Britt's mouth, her little asshole tightening as she was licked. Licking his thumb, Sam reached forwards and placed it on her puckered hole, massaging it gently. Occasionally reapplying his spit, he managed to push his thumb into her up to the first knuckle. She moved up, his thumb popping out of her ass, and returned to her initial position, body parallel to Britt's. Then she looked back at him, nodding. Sam pulled himself from Britt, moving his cock to the other pussy before him, mixing Britt's juices with Chloe's as he pushed inside her. Chloe reached back and grabbed his hand, placing it once again at her ass. Taking the hint, he began to ease his thumb back into her. Britt's hand reached up, cupping his balls, gently massaging them in her palm, fingers at his taint. The added stimulation sent a tingling sensation through his lower body, and he stilled halfway inside her, cock spasming as he shot into his sister, Britt continuing to massage the cum from his balls throughout. He retreated as Chloe and Britt continued, his cum spilling onto Britt's stomach. They were about to leave, but had devolved into one final fuck after they'd finished cleaning up. Watching, he felt a pang of regret that they had to go. This week had opened up so many things to him, and he had no idea how long it would be before he saw his little sister again. He just hoped it was soon.
