MODIFYING TRADITIONS

I opened my eyes drowsily and saw the bare, broad back of my cousin, Shane, shifting on the pullout bed we were sharing. Along with my sister, Colleen, there were actually three of us on the sofa bed in our grandparents' living room. We and our parents - our father and Shane's mother were siblings - were all visiting for Christmas and with the bedrooms all occupied by the "grown folk" we kids were relegated to the living room to fend for ourselves. Despite having lean bodies that comfortably fit on the queen sized bed, with Shane and me at twenty and Colleen at eighteen the adults thought we shouldn't be sharing the pullout anymore. However for the past few years we had protested and done it anyway because it had become our own little tradition. We stayed up as late as we could watching bad movies and enjoying each other's company until we passed out. I was often the first one asleep and essentially would be dead to the world leaving Colleen and Shane to continue talking over the TV.

As my eyelids fluttered shut again, I heard Shane whisper, "Is he awake?"

The mattress shook slightly as I assumed Colleen glanced over our cousin's body at me. I said nothing and kept my eyes closed intending to allow the sleep that was quickly returning to me to take hold.

"Yeah. He's still out," came my sister's reply.

"You gotta be quieter," Shane said as I felt the mattress shift with greater force as he moved.

Colleen's whisper was harsh when she responded. "Well you gotta go easier with that thing. I told you I haven't had anything that big in me since the last time we fucked."

Upon hearing my sister's words the sleep that was about to overtake me retreated. Now awake and alert, I cracked my eyelids open just far enough to see while hoping it wasn't wide enough for the light of the TV to reflect off my eyes. Looking across the bed, I nearly gave myself away as I suppressed a gasp upon seeing our cousin completely naked and my sister without her pants on. He was situated between her legs hovering over her with his hard cock pointing out of his crotch. While it was surprising to see them in such a position, it was the sight of Shane's cock that nearly caused me to exclaim and reveal my wakefulness. As Colleen had said, it was big but even that word seemed an understatement. Easily in the double digits it was definitely long but it was the girth that made his dick imposing. I couldn't imagine anyone's hand being able to completely close around it. Admittedly, his lean frame along with the shadows from the television light might have been playing tricks with my mostly closed eyes but I didn't think what I was seeing was too far off from what I would see in the light of day.

Shane's tone was mocking when he said, "Well maybe if you had sucked on it a little to get it wet, we wouldn't've had that problem."

"Fine," Colleen said with a huff as she sat up. "But if we get caught, it's your fault."

Shane stood on the mattress and tucked his shoulder length brown hair behind his ears. He then aimed his cock at my sister's mouth while he said dismissively, "We'll be fine. Everybody's out cold."

I watched through my half closed eyelids as Shane sighed and pushed his dick between my sister's full lips with one hand while he grabbed a fistful of her dark brown hair with the other. She must have grazed the flared edge of his bullet shaped head as it passed her teeth because I heard him hiss. "Careful."

It wasn't enough to stop him because he fed a little more length into her before pulling back and setting up a steady rhythm fucking her mouth. Less than half his dick was moving through her but it didn't seem to matter as he closed his hazel eyes and leaned his head back in obvious pleasure. "Oh, yeah. That's it. Suck my big dick."

I could see Colleen's own green eyes roaming appreciatively over his body. After a few moments, she lifted her hands to do the same. Like me, Shane was a little over six feet tall with a genetically provided lean body that had been enhanced with regular time in the gym. Neither of us were exceptionally muscular but we had some decent definition on our bodies and my sister's hands were now tracing the defined lines of our cousin's abs and pecs. Eventually, she left one hand playing with his nipples while the other moved back down his torso, over his trimmed pubic hair then between his legs to his swinging ball sack. Despite the chilly but comfortable air, they hung low and swayed easily in countermotion to his thrusting until she took hold of them. She gently pulled and kneaded them earning a series of soft sighs from him in the process.

After a few minutes Shane suddenly pulled out of her mouth. Gripping his shaft, he raised it vertical while pushing his balls into her face and said, "Suck 'em."

Without hesitation or protest, Colleen kissed and licked at Shane's lightly furry sack for a moment before pulling one of his large orbs between her lips. She couldn't insert it completely into her mouth but it must have been enough because he let out a soft moan and curse of appreciation.

While Colleen worked his balls, Shane began to slowly stroke himself. Both of us were uncut but I was surprised by how much extra skin he had compared to me. Whereas my own covered just the base of my head once I was hard, as Shane's fist moved up along his shaft, his foreskin flowed over his tip completely concealing his cock head. When it retreated, the silvery wetness of precum made the supple skin shine. Intermittently, he began to rub his dick over Colleen's oval face. He pressed it against her nose, slid it across her forehead and occasionally smacked her cheeks with it. Eventually he pulled his balls away from her mouth and replaced it with his dick.

As I continued to lay there spying, I couldn't believe that this was really happening. My sister was sucking our cousin's huge cock right there on the bed next to me with the intention of getting fucked by him. I wanted to believe it was a dream, that it was something being produced by my obviously flawed brain chemistry but the occasional soft sound of suction and the random wet noises that came from her mouth on him were hard to imagine as being fake. Not only that, but I could smell the slight funk of Shane's crotch wafting toward me. There was another scent as well and it wasn't until I saw Colleen move the hand that had been on Shane's chest down between her own legs that I realized it was her pussy I was smelling. Using two fingers, my sister began to play with her inner lips that were just peeking out between her tight outer folds and occasionally dipped the digits inside herself. It was never long but it was enough to make my already hard dick jump a few times at the sight. I was just beginning to wonder how long she would tease herself when Shane pulled out of her mouth and dropped to his knees.

"You must be ready now," he said as he pushed her onto her back. "I can smell you and you look like an addict trying not to play with yourself."

"Then shut up and fuck me already."

Shane smirked as he positioned himself between her legs. "Last time you said that, I put it in you and you squealed."

Shane's words made me realize what it had been that had originally disturbed my sleep. The sound of my sister reacting to the discomfort of what must've been his dry entry was the noise that I had heard just before my eyes opened.

Unfazed, Colleen spread her legs wide for him and said, "Yeah, well now I'm wet and so are you."

"Yeah, you are." Shane had pressed his hard length against her slit and was gently humping against her. With long strokes he dragged his cock back and forth outside of her. Despite the shadow produced by his body blocking the TV, I could see the bottom side of his shaft becoming wet with the juices seeping out of my sister's pussy. He added to the wetness with the slow but steady trickle of precum that left his tip. After a few thrusts he began to smack his hardness against the soft flesh focusing on where her nub was still concealed beneath her folds. Colleen began to writhe and moan softly from the assault and gripped his arms and back as she rolled her hips against him. Over the quiet noise of the TV, the sound of their wet flesh smacking together seemed loud in the otherwise quiet night yet would not have woken me if I had still been asleep.

"Shane. Please. I need you in me." Colleen said breathlessly.

"With pleasure." Shane pulled back slightly and positioned his crown just inside her lips. It took him a brief moment to find her opening and line himself up before he pushed forward and buried his crown in one go.

While not as loud as the first time, Colleen let out a whimper of pain that probably would have gone unnoticed had I been asleep. She put her hands on Shane's chest as if that would prevent any further motion from his hips as she said between pants for air, "Wait."

With dark amusement Shane said, "I know we only do this a few times a year but you should be used to this by now. Though I really shouldn't complain 'cause I love how tight you are." He pushed forward a little more and smiled when Colleen let out another quiet moan.

"Give me a minute, dammit."

Shane moved his hips forward a bit more. "Too much dick for you?"

"I swear it's gotten bigger."

"If only. You're just out of practice. By tomorrow night, you'll be used to me again." Shane pulled out until half of his cock head was exposed before pushing back in a little farther. Though Colleen let out another sound of discomfort she didn't try to stop him. He again pulled back until the ridge of his crown left her before sliding slightly more into her. Colleen let out a softer moan at the marginally deeper penetration. Having effectively been given the green light, Shane continued to rock his hips back and forth feeding more of his dick into her. It took a while and I could see his body tense from restraining himself. His jaw was set and his eyes focused intently on her. Despite his obvious need, it was easy to see that he didn't want to do anything that would cause her to cry out. When he was finally completely sheathed inside of her, he pressed his crotch against hers hard and rolled his hips. It was a motion I recognized as designed to stretch her some as well as to grind against her clit. "Fuck, you feel so good."

Colleen responded by arching her back and hooking her legs around his. "You're so deep. I missed this."

Shane paused to tuck his hair behind his ears. "Sometimes I think you only like me because of my dick."

"That used to be true. Now I like you because you know how to use it," she said to tease him.

Shane rolled his eyes and shook his head as he chuckled. "Still a bitch. It's amazing we ever started fucking at all."

"My being a bitch didn't stop you from taking my virginity."

Shane smirked. "You're right. That's what made it fun."

Despite the fact that the three of us often slept on the pullout together during visits, Colleen and Shane had not always gotten along. Being the same age and with many of the same interests, he and I had always been close. Part of the issue between them was the fact that Shane was an only child and didn't know what to do with a younger sibling. When we were kids, his awkwardness around her led to misunderstandings that grew into fights that made them dislike each other. Around the time he and I were seventeen and she was fifteen, something changed. It was abrupt and when asked about it they each just said they got over their animosity. As I watched Shane fuck Colleen with short, slow strokes, it all began to make sense.

After letting out a long sigh of pleasure, Colleen said, "Thinking back, I should be pissed at you for talking me into having sex with you but I can't complain considering how bad some of the other guys have been that I've fucked. But maybe that's the reason I should be mad."

"Because I'm so good? Are you saying I'm the best you've ever had?"

"So far."

Shane pulled his cock all the way out. The hard piece of flesh bucked and throbbed protesting the removal and shined shamelessly with a mix of their fluids. He sat back and rolled her over onto her stomach. "So far? Bitch, you know you'll never have another man fuck you like I do."

My sister moaned as he slid back into her. Her head was turned in my direction and I saw her brow furrow for a moment as she examined my face. I thought I had been caught until she relaxed her face and pushed her ass back against our cousin. "Well, I'm still waiting for you to fuck me."

Shane laid his larger body on top of hers. While Colleen had the same frame we did, her height was only five feet seven inches which made her over half a foot shorter than either Shane or me. His long, broad body completely covered hers as he hooked his arms through hers and locked his hands together behind her neck. He wrapped his feet around her ankles and with her completely secured beneath him, he began to rapidly thrust into her. Like before the strokes were short and their flesh made only the barest of noise as it slapped together. Other than the shaking of the mattress that probably would've gone unnoticed had I been asleep, there was not enough sound to disturb anyone else's sleep. With his head at her ear, Shane asked, "That what you want?"

"Yes. Oh, yeah. Fuck me. Just like that." As she laid there continuing to softly vocalize her pleasure, Colleen kept her eyes focused on me through the fall of Shane's hair. It wasn't just the blank stare of a woman reveling in the sensations washing over her, it was the look of a woman who knows exactly what she's doing. Her eyes moved back and forth across my body obviously sizing me up.

It disturbed me slightly because I had the sense that she knew I was awake and was either waiting for me to reveal myself or enjoying the fact that I was watching her. Maybe both; maybe neither. After a few minutes of Shane on her back she saw my dick twitch and a sly smile crossed her face. I knew I had been found out.

"Would you mind if Cole joined in?"

Shane stopped his hips and looked over at me. "He's asleep."

"No, he's not." Colleen reached over and grabbed my erection through my pajama bottoms.

As soon as her hand made contact, my eyes flew open and I pulled away.

"Shit," Shane said as he pulled out of Colleen with the same mix of shock and fear on his face that I was sure was on mine. He moved to the far side of the bed and sat on the edge with his back to me. "Shit, shit, shit. Fuck, Cole. How long you been awake?"

"Long enough from the looks of it," Colleen answered for me.

"Awhile," I said with some embarrassment. "Sorry."

Despite his mature, masculine face Shane met my eyes with the look of a kid who knew he had done something wrong but hoped he could avoid punishment. "You won't say anything, will you?"

I sighed. Even if I wanted to tell someone, I didn't know if I would be believed. The idea of the two of them fucking each other next to me on the same bed that I was sleeping on was ridiculous. Not only that, but I already felt bad for the hell that would rain down on them if anyone else found out. None of our parents were happy with us having premarital sex and the idea of Shane and Colleen together would send them through the roof. Additionally, I knew that I would also be blamed for what had happened and would be subject to whatever punishment they received for being somehow complicit. "No. I won't tell."

Shane let out a breath of relief. "Cool. Thanks. So what now?"

"I vote for you getting your dick back inside me," Colleen said to Shane without hesitation. To me she said, "I'm okay if you want to keep watching, but I'd rather have another dick to play with."

I didn't hide my horror. "I don't think so."

Colleen moved to all fours on the bed with her ass facing Shane and her head facing me. Seemingly having gotten over whatever qualms he had about my wakefulness, Shane moved behind her and slid back inside my sister. As he set up a sedate, steady pace fucking her, Colleen said to me, "Come on, Cole. You know you want to. Your dick's still hard."

"Maybe, but you're my sister. That's just so wrong and gross." Inwardly, I acknowledged my hypocrisy. Though I was surprised by the sight, I had been okay with watching my sister and cousin go at it. Even worse, it had indeed turned me on and I had been anticipating a nice long shower in the morning to relieve the pressure that had been building in my balls from the show. Yet, at the same time, I knew it was one thing to watch or fantasize about engaging in incest but another to actually do it. Shane and Colleen might be okay with it but I wasn't.

Colleen gave me a lascivious smile. "You're right. We shouldn't. But that's what would make it hot. Even hotter than me and Shane fucking."

"Well that hurts," Shane said with mock offense. "But I don't disagree. Hell, I wouldn't mind seeing that action."

Colleen reached out a hand and grabbed my erection again through my pants. This time I didn't flinch at her touch. "Please. Just this once."

Despite my better judgement, I didn't stop her when she slid her hand beneath my waistband and wrapped her fingers around my bare length. My dick was hard and I did want some relief. I reasoned if I limited myself to a hand job, it wouldn't be so wrong.

As if reading my mind, she began to slowly stroke me and said, "That's not so bad, is it?"

"I guess not," I said grudgingly. I watched Shane thrusting into Colleen at nearly the same pace that her hand was moving on me. Over the course of a few short minutes my arousal grew to the point where I felt the concern about Colleen being my sister diminish. I knew guilt would consume me afterward, but in the moment, my hormones and arousal were in charge. I wasn't exactly okay with what was going on but the almost painful hardness of my dick pushed all other concerns to the side. Needing some relief, I lowered my sleep pants revealing myself to my sister for the first time.

Colleen practically purred at the sight of my dick. "That's nice."

Knowing that my thick, eight inch piece, while above average, was not as large as Shane's I glanced at him for his reaction. For the first time ever, I felt inferior to him. We had always been otherwise evenly matched in most ways and though I had seen how big his dick was, it wasn't until now when I revealed to him how comparatively small mine was that I felt inadequate. I was pleased when he nodded his head slowly in approval. "Not bad. I bet the ladies love that."

"From what I hear, they do," Colleen said causing me to blush. "He had a decent reputation in high school. Now I get to experience it firsthand. I've been wanting to do this for a while."

I didn't hide my surprise. "Really?"

"She has," Shane confirmed. "But we both thought you were too uptight to do anything like this. Hell, you told on us for sneaking that beer last year."

They had a point. I was the good kid who never stepped out of bounds. That's not to say that I was a perfect child by any means, but it was so rare that I got into trouble that it was always a surprise when I did. I maintained good grades, wore the proper clothes, kept my hair cut and styled conservatively, did everything a respectable young man should. Colleen and Shane, by comparison, had been typical teenagers. They were still better behaved than many of their friends, but where there were tons of stories about their antics and misbehavior growing up, everyone would be hard pressed to recall a similar tale about me.

With no warning Colleen leaned down and took me into her mouth and I gasped in a mix of surprise and admittedly kinky arousal. As my crown disappeared beyond her lips I was already having the horniest sexual experience of my life. My sister had my dick in her mouth while our cousin fucked her. It was something I had never imagined and now that it was happening I didn't want it to stop. She was able to get more of my length into her mouth than Shane's, but my girth still prevented her from getting me into her throat. I didn't mind though as she was doing a better than decent job sucking me off. Technically it wasn't the best I had ever felt, but just the fact that it was my sister who had her mouth on me made it great."Shit, that's hot," Shane said. His pupils were blown wide with arousal as he stared without shame at Colleen sucking my dick.

Tentatively, I placed a hand on her head and began to gently control her movements while my hips began to lightly pump my dick into her. After a few thrusts I relaxed more and began to enjoy the experience. Needing questions answered, I asked Shane, "So you guys been doing this a while?"

"I guess about three years now," he said uncertainly. "Remember that summer when she started being nice to me? By that point I'd fucked enough girls to know they often just needed a good fuck to change their attitude. I'd had enough of her shit so I popped her cherry. She didn't fight it either. Been fucking ever since whenever we get together. Cole, if you only knew how many times you were passed out while we fucked around...," he trailed off into a chuckle.

Shane's recollection matched up with what I had assumed. That summer Colleen had hung around me and Shane more than usual. Instead of antagonizing her and trying to push her away, Shane was nice to her and even complimented her. It was weird and for the first part of our vacation she was wary of his intentions. One day the two of them left for a little while. At the time I, and our grandparents, hadn't thought anything of it. I was feeling under the weather and Shane had asked to borrow their car to drive with Colleen to see a movie. When they got home, there seemed to be something awkward between them but the next day they were closer than they'd ever been. Months later, Colleen and I were talking and she mentioned losing her virginity over the previous summer. It hadn't made sense at the time since we had spent nearly the entire summer with our grandparents but I just assumed she meant at some point during that time after we returned home and before we returned to school. Now that I knew the truth it didn't bother me that they had been fucking but it did bother me that they had been doing it with me in the room. "Right next to me? That's messed up."

Shane shrugged unapologetically. "Only made it hotter."

Colleen chose that time to pull off my dick. She looked into my eyes as she slowly stroked me. "It really did. You ready to fuck me?"

"I guess," I said not wanting to seem too eager. I was really horny now and wouldn't be satisfied with just a blow job. Even if she was my sister, it was a pussy and I was ready to do some fucking.

Shane snorted as he gave me a look of disbelief. "Dude, don't pretend. It's too late for that. You like this, just admit it. The three of us are some sick fuckers for getting off on this shit. And even if you think you're too good for this, I bet you still stick your dick inside your sister's pussy. You're too horny not too."

I hated it when Shane called me out. "Fine. Yes, I'm ready to fuck you."

Colleen smiled up at me. "Good."

After she pulled away from Shane, she and I repositioned ourselves on the bed. She laid on her back again and spread her legs while I moved between them.

"Oh, fuck," I said breathlessly as I pushed my dick between her puffy slit. As I slid into her, I could feel that Colleen's pussy was nice and slick from Shane's cock. The warmth of their friction lingered inside her and drew me even deeper. I could feel her walls contracting slightly around me as it adjusted to my slightly smaller girth which was surprising since there had been some pleasant resistance to my entry. The heightened arousal I had felt from Colleen first taking my dick into her mouth paled in comparison to having my dick inside her pussy. The feeling alone was better than any girl I had been with before, but knowing that this was my sister took it to a new level.

"Damn, Cole." Shane kneeled off the side slowly fisting his sex slimed cock as he watched me enter her. "I didn't believe you'd actually do it but you didn't even flinch. You shoved it right in there without blinking an eye."

"Like you said, no sense in pretending. You okay?" I asked Colleen.

"Oh, yeah," she verbalized between moans. "You feel so good. Do you like being inside me?"

"Yeah," I said. My own voice was becoming breathless as I found my rhythm. "It's nice."

"It is." Colleen took a deep breath that turned into a soft moan when she exhaled. "Cole?"

"Yeah?"

"Will you kiss me?"

Without any hesitation I leaned down and pressed my lips to hers. She immediately met it and soon our tongues were playing against each other. Even though the rational part of me screamed that I shouldn't be doing it, kissing my sister while I fucked her was amazing and I began to wonder why everyone said it was so wrong. It all felt too perfect to be a bad thing. Our lips and tongues worked in tandem without any of the awkwardness of a first kiss and, despite Shane's time inside of her, my sister's pussy felt like it was made for my dick. She had tightened nicely around me and fit like a velvety glove. I'd had some pussy that was memorable but none of it matched this. Everything else in the world disappeared and the only thing that mattered was Colleen. Even if our parents, grandparents and aunt and uncle came out of their rooms and started screaming at us, it wouldn't've stopped me from enjoying this moment.

The combination of kissing her and slowly moving my dick through her soon had Colleen in the throes of an orgasm. My mouth swallowed her high pitched moans of pleasure as her body tensed beneath and around me. I could feel her pussy pulsing rhythmically on my dick as well as a surge of wetness as I continued to slowly fuck her. I didn't want to believe the climax was just because of me being with her. She and Shane had been fucking for a while so it was likely that I was just the final straw that pushed her over the edge, but it was hot thinking that I had produced such an orgasm in my sister. When we finally broke the kiss and I looked down at Colleen, I knew this wouldn't be the last time I fucked her.

"That was amazing," she said softly when she was able to speak. The awe in her voice matched what I was feeling.

"It was."

"You guys are sick," Shane said. His amused voice startled me as I had forgotten he was there. "I mean really taboo level fucking sick. You just made your sister cum on your dick."

"That wasn't from me," I said self-deprecatingly. "You're the one with the big dick who got her primed. I just finished the job."

Shane shook his head and chuckled. "No, man. That was all you. Don't get me wrong, I can fuck an orgasm out of her but it's never like that. Shit, she creamed on your dick. That's fucking nasty."

I looked down to where my cock was still moving through her and saw the milky pussy juice coating my dick. My eyes moved to my sister's face and saw that she was watching me without embarrassment.

"I told you I've been wanting this," she said without remorse. "I know you're my brother but you're still a nice, attractive guy."

I didn't know what to say but Shane took care of the silence. "Colleen, you are one sick, horny bitch. And I love it."

She turned her head to say to him, "I know you do. Now get that cock back over here."

"Don't mind if I do," Shane said as he moved above her head. He faced me as he tilted her head back then fed his cock into her mouth. "Oh, shit. Suck my dick while your brother fucks you. Fuck, yeah."

I continued to slowly fuck Colleen while Shane rode her face. He periodically pulled out to feed her his balls but otherwise matched my steady pace gently thrusting into her. I'd never shared a girl before but somehow it felt right doing it with my cousin and sister. Any reservations that I'd had about giving in to my urges were now gone. While I couldn't be certain until after the fact, I was sure I'd feel no guilt later about this. It was all too perfect to regret in any way. For a while soft moans and sighs competed with the wet sound of sex in the otherwise quiet room. The TV still played in the background illuminating the room dimly but it was nothing but white noise.

At some point Shane and I switched positions and I watched with great interest as he worked his big dick inside my sister's tight slit. It was amazing to watch close up. Even though he was well lubed and she was supple and open, her folds gripped his cock tightly and moved back and forth in time with his slow thrusting. The fit was so tight that her pussy lips acted like a squeegee on him scraping the wetness off his shaft on each inward thrust. It collected around her opening and some of it began to turn white as it was whipped into a froth by his movement.

"That's a big fucking dick," I blurted out.

"Hey, you're not so small," Shane responded.

"Yeah, but that's..." I trailed off as he intentionally pulled out until just the barest amount of his tip was still lodged between Colleen's folds to hold him in place. His cock shined wetly with their juices and was visibly pulsing with need. Unlike the untanned, pale skin around his crotch, his dick was deep red with the crown nearing purple from his sustained arousal and I imagined I could feel the heat radiating from it across the distance. "Goddamn, man. That's just...it's... Fuck."

Shane chuckled as he slowly pushed back into my sister. As he did, Colleen emitted a steady low moan and her back arched into the sensation.

While I had never received any complaints about my size or technique, I again felt slightly inferior to my cousin. I knew it was uncalled for and unfounded but I couldn't help the sense of awe I felt from baring witness to his manhood. As I felt Colleen's mouth on me, watching him fuck her was another source of stimulation. It was like watching porn featuring a guy with a big dick fucking a hot teen but with the added bonus of knowing it was my cousin and sister engaging in the act. In the past while watching videos featuring even the biggest studs, I never really focused on the cocks. They were there as an avatar for my own fantasies of working over the featured hot starlet. In this moment, I couldn't get enough of watching Shane's big dick moving through my sister's pussy. It was amazing how her lips held on to his thickness as he withdrew, reluctant to let him go even momentarily. Each movement, no matter how small, produced some sort of reaction from her. Most were sounds of pleasure but occasionally a soft whimper of discomfort left her. More than her noises of satisfaction, those occasional quiet complaints seemed to arouse him further and he often followed them with a few deep, strong thrusts.

As I continued to watch his cock move in and out of my sister, I began to realize it wasn't inferiority that I was feeling, it was simply the acknowledgement and respect that his size commanded simply from its existence. In a video, it was impersonal and a thing from the world of fiction; in person, it was real, truly impressive and there was no way anyone could not be awed by the sight.

Shane shifted backward onto his knees and pulled Colleen's hips up onto his legs while keeping her back on the mattress. He then grabbed one of my hands and pressed it against my sister's abdomen just above her trimmed pubes.

As he continued to thrust into her, I could feel his cock through her flesh. The end was the leading edge of a piston moving back and forth beneath her skin and the flared ridge of his crown was a slight bump marking the limit of it. Behind that, his shaft was steely hard and unyielding to any pressure I applied to my sister's abdomen. While I had no desire to actually touch him, it was amazing being so close to his cock and being able to feel it in action. "Shit. That's hotter than it should be. I'm not into dick, but damn, that's just awesome."

"I thought you'd like that," Shane said with a smirk.

We switched off a few more times before I ended up on my back with Colleen riding me. It wasn't until then that I realized she still wore the t-shirt she usually slept in. As she moved up and down on me, I slid my hands beneath the shirt and began to play with her tits. She was not a busty girl whose chest turned heads, but she did have a nice, perky set that fit her lean body nicely. Her nipples were hard and I pulled and pinched at them making her moan almost continually. Shane had positioned himself to stand above me with his legs straddling my head and as I looked up, I could see his heavy balls almost banging against her chin as he thrust into her mouth. Never in my life did I imagine being in such a position, not just with these two but with anyone. It wasn't because I felt sharing a girl with another guy would somehow diminish my masculinity. It was simply not something that had ever entered my mind. Yet it seemed natural for me to be laying on the pullout sofa in my grandparents' living room with my sister riding my dick while I stared up at our cousin's sack as he fucked her mouth.

"I wanna try something," Shane said suddenly as he pulled out of Colleen's mouth and moved behind her.

"I've told you before," Colleen said sternly, "you're not going back in my ass. You're too big for that."

My mouth dropped open. "He fucked you in the ass? You fucked her ass?"

"A few times," Shane said cockily as he got to his knees and pushed her to lean forward. "She always protests but never stops me. But that's not what I want this time."

As he finished his statement, I felt what could only be a finger trace a semicircle along the bottom edge of Colleen's pussy where my dick entered her. Looking over her back, I saw Shane pull his hand away then move the finger to his mouth. There was a bit of foam and froth from our sex collected on the tip and he sucked it into his mouth and cleaned it off while meeting my eyes. His hand moved back down and I felt his finger return to the spot. This time after tracing along the thin skin I felt him slide the thick digit into her next to my dick. Colleen let out a moan in response and I stopped thrusting as my dick twitched dangerously. I could feel him moving the finger around the edge of her opening pulling and stretching it. After a short while, a second finger joined the first to open her wider.

I was weirded out by what Shane was doing but at the same time I didn't want it to stop. I'd never had a guy touch my dick before and while he wasn't actively playing with it, the feel of him working my sister's pussy while I was inside of it was close enough. The heterosexual guy in me screamed that this was going a bit too far, that I needed to pull out and stick my dick in Colleen's mouth to get some distance between me and Shane, but the horny college guy who had very recently learned that he didn't have a problem with incest was curious and wanted to see where this was going.

With his fingers still pulling at Colleen's pussy, he placed his other hand on her back and pushed on it causing her to begin rocking back and forth on me again. I felt him rest his fingers against my dick as she began to fuck herself on my dick and his fingers. It was a tight fit but after he resumed pulling and stretching her entrance, she quickly loosened around us. After a few minutes of that, Shane rose up onto his knees. He removed his fingers then I felt the spongy heat of his firm cockhead on my shaft. He pushed inside of her next to me and I could feel the strong force and pressure of his exertion against my shaft.

"Shane," Colleen said through panted breaths. "Stop. Too much. I can't."

"Yeah, you can," he said into her ear as he draped himself over her back.

She let out a sustained whimper as more of his cock pushed inside of her but didn't protest further.

Untempered by the layer of flesh that had dulled the feel of his cock when I had pressed on my sister's abs, Shane's cock was hot and hard against mine. The sensation was unlike anything I had ever felt and I let out my own soft moan because of it. When he finally stopped moving, I could feel his cock throbbing and twitching erratically against mine. Our eyes met around my sister's head and I saw a look of unrestrained arousal on his face.

After staring at each other for a moment he tucked his hair behind an ear and asked, "You cool? This okay?"

So overloaded with sensation and coming to terms with feeling his large cock against mine I could only say, "Yeah."

After hearing my response he raised his chest off Colleen's back and gripped her hips. Looking down at what I assumed was our joined flesh he began to slowly withdraw.

I felt the drag of his bare, hard, slick dick against mine. While it appeared practically straight, I could feel the ripples and waves of his rigid flesh as it moved. Having pushed well beyond my own cockhead, I felt the bottom, bifurcated side of his glans scrape against my tip then continue down my shaft. It continued until it reached Colleen's opening then reversed course just as slowly. When it did, some of his foreskin bunched up and folded in on itself from being stuck to my own skin. After a few passes, the friction between our dicks decreased and there was only smooth motion against me. I could only assume it was because of him depositing precum on me each time he pulled back. With my own cock straining for relief I tentatively began to thrust up into Colleen with a completely different rhythm.

"Oh, fuck," she said breathlessly but with intensity. "So full."

Shane echoed her sentiment. "Goddam, this is amazing. I can feel you fucking your sister."

"I can feel you fucking your cousin," I said with some humor but with just as much feeling behind the words.

Shane's eyes met mine again and something unspoken passed between us. In our stares was the silent acknowledgement that we were also enjoying the feel of each other's cock against our own. I knew he and I would never take it further but I also knew that this would not be the only time we shared my sister's pussy. It simply felt too good not to do it again.

Our union was short-lived as Colleen began to pant heavily as another orgasm approached. Hoping to stifle her sounds, I pulled her mouth to mine again for a kiss. Either unconcerned about her increasing moans or surrendering to the power of his own fuck, Shane began to move faster inside of her. While not too loud, the sound of their flesh slapping together became audible in the room. Meanwhile, I continued to move slowly inside of her trying to hold back my own eruption. In reality I didn't need to move much as my sister and cousin continued to stimulate me. Too soon, Colleen emitted a muffled, high-pitched whine announcing her orgasm. Almost immediately I felt her pussy pulse, rhythmically squeezing me and Shane closer together.

"Holyfuckinghell," Shane said after inhaling a sharp breath.

Against me, his cock swelled and became even harder. I could actually feel the initial wave travel up his shaft and when it reached his tip in the middle of an outward stroke, I felt the hot stream shoot out of him and race up my shaft before being stopped Colleen's wall and coating my own crown. Because his hips had slowed slightly as his cock pumped his load, the next shot also covered my dick as he slid back inside. At the end of that thrust with his cockhead deep inside her, I felt the third volley ricochet off her walls to fall back onto me. Each volley was accompanied by a powerful jerk of his dick which further stimulated my own rod. The heat of his continuing ejaculation combined with the now nonexistent sensation of our flesh gliding against each other while my sister's pussy massaged us was too difficult to resist. I thrust as far as I could inside of her and gave up trying to hold back. My dick felt like it exploded as it began to rapidly add to my cousin's cum inside of Colleen. Surrendering to my orgasm, I closed my eyes and let my arms fall from her onto the bed in defeat. While my dick pumped what felt like a lifetime of cum into my sister, I could feel her pussy still throbbing around me along with Shane's cock continuing to pump and twitch as he continued to fuck out his load.Even though Shane had a head start on me, I was the first to completely empty my balls. As he continued to slowly slide his cock back and forth, I could feel the hot, wet dregs of his load seeping out of his dick onto mine. Overstuffed with our cocks, Colleen's tight pussy could not contain everything Shane and I had given her and the excess seeped out of her with each of his backstrokes. It flowed down and around my dick to pool in my pubic hair and balls. The wetness outside of my body cooled rapidly and was a sharp contrast to the heat only inches away inside of her. As Shane continued to massage Colleen and me with his cock, the three of us were quiet as we caught our breath. Even though all of our sex noises had been soft and wouldn't have carried far, the silence that followed our orgasms suddenly seemed deafening.

"Fuck that was hot," Shane said when he finally stopped moving. He had pushed all the way back inside and our slowly softening cocks remained pressed together. Continuing to speak, he met my eyes. "I'd do that again any day."

"So would I," I admitted with a smile.

"I would agree to that," Colleen said sounding dazed. "But I think I'm going to need some time to recover. My pussy feels broken."

"Feels fine to me," I said before I pulled her mouth to mine in a quick kiss.

Shane pulled out and sat on back on his haunches. "I would tell you two to get a room but that would be hypocritical of me and I really wouldn't mind watching that shit go down. Fuck, Cole. Maybe we did break her pussy."

With the removal of Shane's cock, I could already tell Colleen was loose. Not only from the way she didn't close around me but from the rush of fluid that had followed his withdrawal. It was as if his cock had been a stopper plugging a drain. Warm wetness flowed out of her down my shaft, around my balls and along my ass crack. There was so much watery jizz between my cheeks that an observer could have easily mistaken me as the one who had been fucked and seeded. The smell of our sex was powerful and I worried it might linger in the air well into the next day, not to mention the stain it would leave on the sheets. But in the moment none of that mattered.

I felt Shane press some fingers into Colleen again next to my dick and this time there was little to no resistance as he moved his fingers around her hole.

"I wish you could see this," Shane continued. "She's fucking gaping."

He grabbed one of my hands and guided it to her hole. I slipped two fingers inside of her and even with his fingers still there along with my much softer dick they went in easily. Shane and I pulled and slid our fingers around my sister's pussy exploring her. He met my eyes a few times as our fingers played against each other in a way that was not intentional yet not accidental. At one point he removed his fingers and stared at me as he sucked them clean before reinserting them. We then began to finger fuck her slowly in countermotion. My fingers slid out as his slid in against mine before reversing direction.

Despite letting out a pleasured sigh, Colleen said, "Let me know when you two finish with your bromance back there. Though I completely understand if you need me here to feel better about yourselves."

Shane and I quickly pulled our fingers out of her.

"Fuck you," Shane said as he turned to sit back against the head of the sofa bed next to us. Because I was in the middle of the mattress, the right side of his body pressed against my left. "There wasn't anything gay about that."

"You're the one that decided to take on two guys at once," I said as I pushed Colleen off me but didn't otherwise move.

Colleen gave us a look that said she did not believe us. "Whatever. I'm going to go get cleaned up."

Shane and I were quiet until the bathroom door closed.

Once we were alone, Shane slapped a hand down onto my leg and said, "You're a mess, dude."

I sat up to survey my body and the phrase "rode hard and put away wet" came to mind. There was pussy juice and clumps of cum in my pubic hair, on my softening dick and balls, and even on my thighs. Shiny trails of it cascaded over the side of my body and flowed onto the mattress below. Normally I would have been eager to clean up but with Colleen in the only readily available bathroom I couldn't do anything about it.

Glancing over at his crotch, I saw that his wet cock was still bloated. It wasn't the usual soft swelling that accompanied a deflating dick. Instead, it was puffy and looked like it had truly been rode hard. Even though it was well on its way to being completely flaccid, it was still imposing and I couldn't help staring at it as it twitched and jerked drunkenly as it shriveled.

"Staring at a guy's cock like that might get him thinking," Shane said softly. He gave my leg a light squeeze reminding me that his hand still there.

I looked up at my cousin's eyes and felt no awkwardness about being naked with him and covered in some of his cum. We had always been close and after what had just happened embarrassment was not an option. "I told you, that thing's impressive. Can't help but stare at it."

He reached down with his other hand and pulled on his dick a few times then shook it. "You like my big dick, do ya?"

I couldn't help chuckling as it flopped around limply. "Never mind. It looks kinda pathetic now."

"Yeah, well you won't think that the next time you see it."

"What makes you think I want to see it again?"

Shane raised an eyebrow. "Come on, Cole. You know we're doing this again before we leave. Besides, there's no way you're not fucking Colleen again and I want to watch that at least once. Even if you think you're not going to, she wants you. We've done a lot of fucking, but I promise you she's never been into a fuck with me as much as she was with you. She creamed on your cock, man!" He squeezed my leg for emphasis. "I know she's had some good orgasms with me but she never came as hard with me as she did with you."

I didn't know what to say but I knew Shane was right. Not only would the three of us be together again during this trip, but even after we returned home, Colleen and I would most like continue fucking. It bothered me hearing that Colleen was into me because for me it would just be sex. But that was a matter for another day. My only thought was the change in my outlook. I liked the idea of fucking my sister and would definitely do it again.

"Look at you two," Colleen said as she approached the bed. We had not heard the bathroom door open and she startled me and Shane causing our cousin to snatch his hand away from my leg. He and I cursed softly in surprise as Colleen said, "You guys are so gay for each other."

Shane glared at her. "You say that like it's a bad thing for two guys to be comfortable with each other. And even if we were gay, would that be a bad thing?"

"No," she said as she sat on the edge of the bed. "That'd be kinda hot, actually. I'd watch."

"You're so messed up," Shane said as he shook his head.

"No worse than the two of you fucking me at the same time. Sex is sex. If you two want to give it a try, I'm all for that."

"Thanks, but no thanks," I said as I climbed out of the bed. "Love ya Shane, but not that much."

"I'm not offended at all," he replied.

After taking my turn in the bathroom, I climbed back into bed. Colleen was in her usual spot between me and Shane and I felt bad that she was laying in the large wet spot but she assured me she was fine. As I got settled, she pushed back to spoon against me. Without any hesitation I wrapped my arm around her body and pulled her close. Shane moved closer to her and pressed himself to her front. He draped his arm over her as well and his hand rested on my side and began to lightly stroke me. After raising my head slightly to give him a smile, I moved my hand to do the same to him. It felt completely natural, lacking any awkwardness or embarrassment. I heard the crackling wetness of the two of them making out for a moment before Colleen turned slightly to give me a deep goodnight kiss. Even though we all knew we couldn't be found like this in the morning, we quickly fell asleep. As my eyelids closed, I thought how happy I was that the three of us shared this bed in our own little tradition.
