How Far Would We Go for His Sister?

***All characters are 18 years or older. ****

"Dude, your sister is so fucking hot." 

"Tell me about it." 

It was the start of summer break from college, and I was in my best friend John's room, looking through the window and down at his backyard, where his younger sister was sunning herself by their pool. I had known Lila since she was young, and she had always been John's annoying little sister--until one day, she just wasn't. It felt like, in the blink of an eye, she went from pest to eye candy. 

Down by the pool, she wore a tight, yellow bikini that showed off her C-cup tits, taut stomach, and long legs. Her red hair was splayed out on the lounger she lay in as she tried her best to tan her milky skin. She wore dark shades that made it impossible to see her emerald-green eyes. 

John grunted as he finished his set with the bench press and sat up. Sweat made his skin glisten, and the recent effort made his muscles pop. He had been working hard on his body for years, and you could tell. 

"You know I caught her the other day sucking her boyfriend's cock in the living room? She's such a slut and has zero shame. My dad was in his office with the door closed, just a few yards away!" John said with an incredulous laugh. Even at only 18, his sister body count probably rivaled ours.

"Jeez, did she see you?" I asked, hungry for more details. 

John was toweling off and smirking at me. "Hell yeah, she did. She fucking winked at me and kept going. No shame, I'm telling you." 

I gave a laugh. "No way. You should have joined in," I joked. 

"Haha, right. I would have loved to spit roast her right there on the couch, but you know, maybe the boyfriend would have freaked out," he boasted. "So I just came up here and beat off to the image."

"Oh, I'm sure it was purely the boyfriend's fault that you chickened out," I teased. 

John and I had been joking a lot like this lately. He made no secret of the fact that he lusted over his sister. At least not with me. My phone was filled with sneaky, dirty pictures he took of her when she wasn't looking. "For the spank bank," he entitled the most recent one of her laying on the couch in a sports bra and thong. If he had the chance, I know he wouldn't hesitate to fuck her. It felt freeing to share such filthy thoughts with him. 

He suddenly looked like he was struck with a brilliant idea. "Let's go down there and sun by the pool with her. I bet the more time we spend with her, she'll fuck one of us by the end of summer." 

"Beats oggling her from all the way up here," I said, "but I don't have a bathing suit." 

John grinned. "That's the best part. You can borrow this." He held up a tiny speedo from our days on the high school swim team. He flung it at me, and I swatted it away.

"Ugh, fuck that. I haven't worn one of those in years," I said, mock-offended. 

"Don't be a bitch," John shot back as he turned around and dropped his shorts to flash me some ass as he changed into his swim trunks. I quickly stripped and slipped on the way too tight speedo. It took some maneuvering to stuff my junk comfortably in there. 

We grabbed some beers and made our way to the backyard, putting our towels down close to Lila. 

She did nothing to acknowledge our presence, and I assumed she was dozing as she tanned. I took the chance to get a closer look at her body. Not that I haven't had plenty of past opportunities, but I'll take any chance I can get. Her pale skin was turning pinkish in the sun and glistening from a mix of sunscreen and sweat. I watched a bead travel down her neck and disappear into the line of her small bikini. What I wouldn't have done to have been that bead of sweat. 

John and I sat up on our towels, clinked our beers, and took a swig, enjoying its coolness on the hot day. The sound of the beers finally got Lila's attention. 

"Hey, give me one of those," she demanded. 

John gave a small laugh. "No way. You know you are too young for that still." 

"Oh please. What are you, a cop? Mom and dad won't be home until late, and it's hot. Give me a beer." 

John looked over at me and smiled. "OK. If you want it so bad," he said as he grabbed one of the cans and leaned over me to give it to her. At the last moment, he changed course, reached down to pull slightly at the line of my speedo, and shoved the ice-cold can to nestle near my dick. "Come and get it." I was as shocked as Lila, but part of the shock might have been the sensation of something freezing rubbing against my balls. My dick tensed but didn't get hard, I assumed because of the cold. 

"Ewww, ugh," Lila protested, but with a bit of a smile behind her disgust. She tipped her glasses down and looked at me with those green eyes. "Mark, can I have that beer, please?" She adopted the look of a young child asking for extra dessert. 

I smiled at her and leaned back to lay down, feeling the speedo stretch to its limits with the can poking out the top. "Oh, I dunno," I said, grabbing my crotch beer. "I kind of like where it's at. I'd hate to part with it." 

"Oh, for god's sake. You two are such perverts." Lila launched forward and roughly yanked the speedo up enough to grab the beer from me. I gave a laugh and a little yelp at the sensation of this jostling my junk. 

John burst into laughter, and Lila cracked the drink open and took a sip from the can that had been cozying up to my dick. She then joined us a bit in the laughter. "Such dorks." She then lay back on the towel, this time on her stomach, and sipped the beer while scrolling through her phone. Her ass stood out prominently and was framed beautifully by the suit that covered very little. I wanted so badly to bury my face in her ass and do horrible things to her. I looked over and could see John sharing the view as well. 

John and I stood and made a bit of a show, rubbing lotion on ourselves and catching Lila, giving sidelong glances. She smiled a bit as we offered to do each other's backs, and she was even a little delighted when John gave me a tap on the ass to let me know he'd finished. 

We three laid out in the sun for a while, and all my horniness aside, it felt great to get some sun. I must have dozed off because the next thing to wake me up was the sound of the water in the pool splashing about. 

I lifted my head up, feeling like a lightweight for letting the beer and sun impact me so much, to see John's head bobbing up and down in the pool. 

"Shit, must have dozed off," I said to Lila, who was still on the towel next to me and had returned to sunning her front. 

"Yea you did. One beer is all it takes for you, I guess. Pussy," Lila joked. 

"Whatever," I brushed her off, nodding my head in my friend's direction. "You didn't want to join your brother in the pool? Keeping me company?"

Lila gave me an 'as if' look." He asked me to join him, but then left that behind, so I opted to stay here." She had nodded her head at John's swim trunks that had been discarded in a pile on the ground next to the pool. 

I laughed and was inwardly amazed at his bravery. He really did not care if she knew what he wanted from her. "That must be awkward for you. Seeing his junk." 

She laughed this time. "Are you kidding me? John has never been subtle. He basically walks around the house naked. Mom and dad are convinced he wants to be a nudist. I know he's just doing it for me." 

"Oh yea?" 

Lila leaned forward. "Oh yea. It's pretty clear that you don't need to pass my doorway on the way out of the shower. He stops there and chats with his dick out, absently playing with it as if he's drying himself. He just wants the attention."

My dick started to grow, thinking about Lila staring at her brother's big dick and hard body. I felt my voice catch a bit. "Umm, well, you don't seem so bothered by it." We both looked over to see John floating on his back, his dick just floating there with him. 

Lila looked down at the growing stiffness in my speedo. "Both of you are so predictable. You want me to squirm and squeal because of a little dick show. You want me to pout like a little girl and be shocked so you two can teach me a thing or two about cock." 

She put on a mocking little girl's voice, pouted her lips, and squeezed her arms together to make her tits pop. "Oh, please boys! Why is your thingy so big and hard? If I squeeze it, will it make it go down? Does the stuff leaking taste good? Please. I'm not so little anymore to be impressed by you two. Plus, sometimes I think you two are more into each other than me." She winked as she grabbed another beer from next to me. 

"Fuck off," I said defensively, taking another for myself as well. 

"Fuck who?" John said as he waddled up, his wet dick dangling in front of him. 

"Your sister was saying how unimpressed she is with that," I said, pointing to his manhood. 

John gave it a grab and waved it in her direction. "Bullshit. She talks a big game, but she couldn't handle it anyway. I saw what your latest boyfriend was offering, and it was sad." John wrapped a towel around his waist and gestured to me. "Come on, man, let's get out of here." 

John and I left a smiling Lila to nurse her beer and headed inside through the sliding glass door. I had a seat on the couch, and John went to the kitchen to get another round of drinks. He flopped down on the couch next to me, looking dejected. 

"Lila's such a tease man. I know she wants it," he said, almost muttering to himself. "Whatever," he said as he put on the TV and started looking for some sports highlights to distract himself. 

On my third beer, I was just enjoying the light buzzed feeling. It was so strange to witness them interacting like this. For all the years he and I had been talking about his sister, I realized I had never spent much time with the two of them together. It definitely wasn't the norm to be so open with his lust for her or even their openness with each other. 

I was lost in thought as I heard the sliding glass door swoosh open, and Lila stepped into the living room holding an empty beer can. She stepped right in front of the TV, which annoyed John to no end. 

"What do you want, Lila? I'm trying to watch." 

She turned to the TV as if to check and gave us a view of her ass in the too-small bikini. She then walked up to it and used the button to turn it off. 

"Hey!" John protested. 

Lila turned, clearly a little buzzed as evidenced by her slight sway. Or was I swaying? 

"Don't be like that, John. Why are you so pissed?" Lila asked, clearly sounding concerned. 

"I'm not," John lied. I stayed quiet, watching the sibling drama play out. 

"I think you are. And I think it's because you want this," she said, running her hands down and lightly stroking her pussy over her bikini bottoms. 

"You're such a tease." John said, shifting in his towel. 

"I can be, yeah." Lila said. "But I'm right. You want your little sister." As she said this, she did a slow turn, letting her arms roam. 

What the fuck was going on? My dick didn't care. It was starting to get hard, making an obvious tent in my speedo. 

"What would you say if I told you that you could have me? Both of you could. Right now." 

John and I sat a little straighter. 

"What are you talking about?" John said, seeming to brighten, but still with some reluctance in his voice. 

"I'll let you finally have me. All of me. All you two have to do is do exactly what I say. Deal?" 

"Bull. Give me some proof that this isn't just some childish bullshit." John retorted. 

Lila walked up to where we sat on the coach, half bent, and placed a hand on each of our bulges. I instantly got rock hard at her touch, and from the look of the towel, so did John. 

"How's that?" she said as she gave a squeeze.

"That's...that's really good," John said, delighted. "Let's go then." 

Lila lifted her hands and backed up a bit. "Good, but deals off if you disobey me. I am telling you. I'll only reward obedience. Piss me off, and you are left with the bluest of balls." 

"Deal," John responded. 

They both looked at me expectantly. 

"Um, I dunno," I said. This was all too fast and too real. Locker talk is one thing. But actually, balling my best friend's sister with him was a whole other thing. 

"Do you want to fuck her or what? Just go with it, man," my best friend implored me. 

I swallowed hard as Lila waited for my answer. She had one arm crossed over to the other, hugging her ample tits, while her free hand played with the lining of her bikini. 

"I don't have all day," she said impatiently. "Stacy is waiting for me at her house, so this is a limited-time offer."

Either because he was horny or to encourage me by breaking the seal, my friend was already lifting the towel to show off his impressive manhood. I had seen it a hundred times, and so had his sister, apparently. But this was now in a purely sexual context, and that made everything take on extra weight. His cock leapt forth from the towel and stood proud. The v-lines at his hips led down to his trimmed public hair, which made his dick seem even bigger. It curved slightly up and sported a fat head. Seeing him sitting there so hard, with his muscular build, was extremely hot. 

I looked up at Lila's face, half expecting a look of shock or embarrassment--something to signal that this was all a lark that had gone too far. Instead, her face only held a small smile as she looked down at her brother's body. Her eyes hardened a bit when they flitted toward me, making her appearance suddenly stern. "I'm waiting, Mark."

I looked over to John again, who smiled at me and raised his eyebrows as if goading me on. He had been lightly stroking his shaft already. 

Fuck it. I lowered my speedo, and the relief from pressure felt good. My own dick made a dramatic entrance and compared well to John. I've always been blessed with my cock, and my body was nearly as nice as my friends, owing to a lot of competitive workouts between the two of us. 

Lila stepped forward. Once again, she reached out her hands and grasped our dicks, but this time there were no fabric barriers. Her little hand felt amazing as she lightly grazed our skin. 

"Mmm. I'm not going to lie. You two have nice dicks. You might be right, John. You are bigger than my boyfriend." We stayed silent, letting her play. She let go suddenly and backed up a few paces. 

"I'm going to strip for you boys, and I want you to jerk for me."

Not needing to be told a second time, we both reached for our cocks and started to stroke. 

"No, no," Lila chided. "You are going to jerk each other for me." 

"But..." I began to protest, but Lila cut me off. 

"Then we are done," she said curtly, placing her arms to cover her breasts. 

Before I could think, John reached over and grabbed my staff. Lila smiled at my shock. John's hands were a bit rougher than Lila's and obviously much larger. His grip just barely touched the tip of my dick, and a wave of strange shame and guilt washed over me as my body responded to his touch. "Ohh, mmm," I muttered. 

"That's it. It's ok," Lila encouraged as she undid her bikini top. "See, you get a little reward." She released the string, and the top fell forward, revealing the most perfect tits I had ever seen. Her tiny pink nipples made her C-cup tits seem even bigger. 

As if in a trance, I reached over to grab at my friend. His shaft was hot and rock hard, and he gave an involuntary, muffled gasp as I grabbed him. 

Music began to play, initiated by Lila from her phone. "Stroke," she commanded as she swayed to the music. Her tits swayed with her, and she groped herself and made seductive movements. John and I obediently stroked each other, going slow and grunting with pleasure. 

Lila made her way to us and stood between us. She reached down and replaced our hands with hers to continue to stroke us. 

"Grope," she commanded, and again, John and I obeyed happily. I grabbed a handful of her thick ass while John groped at his sister's tits. I let my hand slide between her ass cheeks and down and around to feel her pussy. Lila gave a groan as I explored her body, forcing my way into her bikini to feel her wetness. 

As we explored, Lila raised her hands up to our faces. "Taste," she commanded. 

This time, we both hesitated. Her fingers looked shiny with our precum. "Taste!" she said more forcefully, and without giving us much choice, she shoved her hands into our mouths. 

The taste was at first bitter, and the precum seemed to coat my tongue in a strange way. But then the bitterness gave way to a bit of sweetness, and I realized I enjoyed the taste. I am not sure exactly what John thought, but I looked over to see him sucking eagerly at his sister's fingers while pinching her nipple hard. 

Lila started a bit and took her hand back to give John a sudden light slap on the face. "Not so hard!" 

John smiled and grabbed her hand to bring it to his cock again. 

"Uh uh," she admonished. "Too eager." Then she turned her head toward me. "Mark, stand up. John, we kneel." I did as I was told, knowing where this was going. 

She pulled John down to the floor with her, and they both kneeled before my dripping cock. John seemed nervous as he guessed what his sister's next commands would be. But she surprised him and kissed him while stroking me and letting him grope her. I almost came from the sight of the siblings kissing. Lila released the kiss and brought her mouth to my waiting dick. 

The feeling of her warm mouth taking my dick in sent electric shocks through me. John licked and sucked hungrily at his sister's tits. The sound of slurps, accompanied by my groans, filled the room. 

Lila then popped my dick from her mouth and brought John's chin up to kiss her again, this time millimeters away from my shaft. My cock ached for attention as I watched them kiss. To my surprise and relief, Lila alternated between kissing her brother and licking my head. She then put her hand on the back of John's head and pushed it to my tip. "Suck," she said gently as she pushed his head ever closer. With her other hand, she grabbed John's shaft. It was clear--suck my dick, and she'll stroke you. 

John looked up at my eyes for the briefest of moments. I could see his reluctance, but he took me in anyway. I groaned with pleasure. John sucked my cock with a lot more skill than I thought he would. Had he done this before? Although not as skilled as his sister had been, his mouth gripped tighter at times, and his tongue danced on my cockhead in ways Lila couldn't due to her small size. 

"Fuck, that's good," I groaned. I hadn't even meant to. I wasn't supposed to be enjoying this, but it felt so good. John seemed to be encouraged, either by my groans or his sister's rapid stroking. He took even more of me in and slurped loudly as he let me fuck his face. 

After a while, Lila seemed to grow impatient. She had been fingering herself as she stroked John, and she must have needed more. She stopped stroking and backed up a bit. 

"You've been such good boys. Now you can use me how you want." For all her dominance before, she now looked at me and her brother with innocent and eager eyes. She wanted us to choose what we wanted to do to her. 

John wasted no time. Wiping his mouth, he stood up and fed his sister his cock roughly. Lila let out a muffled yelp, but closed her eyes and started to suck off her brother. 

Not wanting to waste time either, I kneeled down and took her nipple in my mouth. I had wanted to suck these so badly and did not want to miss my opportunity. Her tits felt good in my hands and mouth, and she seemed to love my attention. I then moved south and stripped off the last remaining piece of her bikini to attach myself to her pussy. I felt the velvety slickness of her opening and tunneled my tongue inside, tasting her deeply. She gave a deep groan of pleasure as I made my way up to her clit and attacked it with my tongue. Her mouth released her brother's dick, and she screamed with pleasure. With one hand, she kept my head in place on her clit and stroked John with the other.
