Introduction: Big Brothers shouldn't be so sexy...

I don’t really remember the first time I got that “tickle,” that urge down below that told me I was turned on. But I do remember the first time it was strong enough that I decided to do something about it. I was walking past my past my brother Ryan’s room and he was taking off his shirt. The sight of his chest and his firm abs, his back when he turned around, all that bare skin...the hint of his navy blue underwear, it made the tickle grow from a tickle to a throb.After that day I paid a lot of extra attention to Ryan. He was used to attention from girls, being over six feet tall with dark hair and pretty blue eyes that rivaled my own in intensity, but for him getting attention from me was a novelty. I usually minded my own business, much more content to call my girlfriends on the phone or go shopping than hang around the house with my older brother. I knew my change in behavior was a total 180, but still, when I started hanging around his room asking for hugs and kisses he was always very free with the love and he never made it seem like a big deal. He liked to dote on me, but I could tell he also genuinely liked to touch and be touched. That was how I knew I could eventually get him.Ryan and I were a little less than two years apart, and while our younger siblings got home later than us especially due to soccer, ballet and other extra curricular activities, Ryan and I got out of school at the same time, which meant we were often home alone for a few hours. Our favorite thing to do during that time became either watching movies or playing video games. Whenever we would watch movies I would sit really close and either put his arm around me or drape my legs across him.At sixteen I was tall with a small waist, athletic figure, C cup breasts, and long shapely legs, so I used those things to my advantage. I wore low cut tank tops a lot, and either short skirts or shorts. When I wore short shorts and rest my legs on him he would rub them, running his hand up and down my thigh. That always gave me the tickle.One day when he was stroking my legs, I slightly parted them, hoping he would take the bait. He did. He ran his hand up and down the inside of my thigh. By this time I was very wet. Ryan was very cute, and all the girls knew it. Even though I was his sister I wasn’t blind. My pussy was well aware that a prime available male was close enough to reach out and touch.“That feels good,” I said with coy appreciation, as he petted me.He smiled and gently squeezed my leg then moved his hand up higher, keeping his eyes on me to gauge my reaction. I smiled and parted my legs more, meeting his eyes in a daring gaze. Once again, my big brother rose to the occasion. His hand traveled higher and his fingertips ghosted over the seat of my panties.“Ooh, you are making me feel so nice,” I said.“Really?” he asked, looking excited. “You don’t mind?”“No. Touch me more,” I said.He swallowed hard but did as I asked. I gasped when I felt him directly rub his fingers back and forth, stimulating my clit.“Right there,” I sighed, adjusting my tank top to draw attention to my breasts.“Is my baby sister horny?” he asked, with a sly smirk.“Mmm,” I said. “Can you help me?”“Let’s see,” he said, wriggling his fingers into my panties. By then my heart was pounding in my chest. He quickly located my clit and began to rub it. I was so wet that his finger slipped over me easily again and again, bringing me nothing but pure pleasure.I reached for his other hand and put it on my breast. I had stopped wearing bras around the house, so I could clearly feel the warmth of his hand on my nipple and the sensation of his fingertips squeezing and pinching at my hardened nub. I began to moan loudly as he felt up my tit and played with my clit.“Oh yes...yes...” I sighed, shamelessly humping his hand. I came in a burst of heat, moisture and sparks, twitching and sighing as I shuddered in release.“How was that?” he asked. “Did I help?”I smiled. “I feel so much better. But now it looks like you need a little help,” I said, lowering my eyes to the sizable bulge in his jeans.“Y-you really want to?” he asked, utterly shocked.“I’ve never touched one before. Can I touch yours?” I asked.“Yeah,” he said, still looking shocked but also very willing.I unbuttoned and unzipped his jeans reaching in to pull his cock free. It felt warm in my hand and flopped out long and hard.“Wow,” I said. “Are they all so big?”“Not all,” he said with a smirk.“So modest,” I teased, grasping it gently and starting to stroke it. He looked like he was really enjoying it but he was staring at me transfixed, probably still wondering if this was really happening. Meanwhile his cock was getting harder and longer in my hand.“Why are you doing this?” he asked.“Because I like you, idiot,” I teased, stroking it faster. He groaned and thrust himself into my hand.“I didn’t know you liked me this much!”“Now you do,” I said.I wanted to see him cum, but right then we heard the car pull up in the drive and then the voices of our mom and little brother and sister. Ryan shot out of the room like a bullet, almost tripping on his jeans. I laughed heartily and decided that I would definitely find a way to see him cum soon.For the next week things were a little weird. Ryan was really shy around me or something. He seemed nervous. He wasn’t avoiding me, he just didn’t seem to know how to act. After a while I figured out that he must be wondering if what we did the week before was a one time thing.To get my point across I dialed up the touching. If we were sitting next to each other at the table, I’d lay my hand on his thigh. If we were cleaning the kitchen together I would come up behind him and press my boobs into his back. Or I would bend over so he could see up my skirt.One time I did that; I had just bent over to pick up a fork that fell on the floor and when I sat it on the table before I straightened up he came up behind me and pressed his really hard cock against my pussy. I got so turned on I had to clutch the nearby chair or I would have fallen over.“Do you see what you do to me lately?” he asked, grasping my hips and pulling me back firmly onto his cock.“Oh God,” I sighed, my head swimming with dirty thoughts and ravenous need. “Oh fuck...”“What...a...dirty...mouth,” he said, punctuating each word with a thrust as he started to hump me. He grabbed my skirt and pulled it up over my ass so that he saw the red thong I was wearing. “Mm...I like these.”At this point I was rubbing my pussy against the long hard bulge in his jeans and my clit was throbbing beautifully while his hands moved from my hips to caress my ass cheeks as he continued to hump me with that rock hard bulge in his pants.“Oh Ryan, I’m going to come,” I gasped out.“Really?” he asked. “Just from this?”“Yes, yes...Ahhh!” I cried out as quietly as I could as I came so hard I wet the seat of my panties and made a big wet spot on the crotch of his jeans.“That was so hot,” he said, when I turned to face him. I was going to go in for a kiss on the lips and see what he would do, but we heard Dad’s heavy footsteps coming down the stairs and we both had to scramble to our rooms.All night long I thought about how Ryan must be jerking off all the time thanks to me and my newfound desire for him. But that was such a waste, I wanted to be there to see him to come. I wanted to be the one to make him erupt in sheer carnal bliss. I couldn’t wait any longer. I had to have him.The next day after school we got home and met up for our usual time of hanging out on the sofa watching TV. I’d had the tickle all the way home thinking of how I would get my hands on him. As we sat there staring at the screen, both of us probably thinking about nothing but sex, I reached out and took his hand, then put it between my legs. He didn’t hesitate or change his position, he just immediately started to touch me, running his fingers over the seat of my panties and making me wetter.I wanted more so I spread my legs, draping one over his leg to give him better access. He pulled my panty seat aside and touched me, running his finger between my pussy lips and all along my sensitive flesh. When he reached my button he rubbed and stroked it until I was squirming and emanating heat. Then he slid his finger up inside me. I let out a moan. I was so wet it didn’t hurt at all, it just felt good.Sliding an arm around me he pulled me closer and kissed my neck as he continued to finger me. My mouth fell open and I sighed as his hot wet mouth traveled up my neck, kissing, nipping, sucking. I moaned softly and creamed on his finger while he kissed up to my ear. He sucked and nipped at my earlobe then made his way over my cheek to my lips and we kissed deeply, our tongues caressing each other and battling for dominance.I knew Ryan was ready for more contact because he unfastened his fly and reached into his jeans to pull his erection out. He put my hand on it and I grasped it gently, pumping my hand up and down. As he got more and more excited he started to thrust his hips, fucking my hand at the same pace that his fingers fucked my pussy. I became so horny I was desperate and I needed release like I needed my next breath."Can I put it inside you this time?" he whispered."What about protection?" I asked."I won't come in you.""Will it hurt?" I asked."Just a little.""...Ok," I said, but truthfully I was almost too impatient to even pretend to have to think about it. I wanted him inside me now.He laid me back on the sofa and I was so excited I could hardly keep still. He spread my legs wide and knelt between them, bringing the head of his erection to my entrance. He rubbed it against me, up and down, over my clit, making me throb in anticipation.Bracing himself with a hand on the sofa arm by my head he began to push his way inside me. It didn't hurt much. I felt a sting as my natural barrier gave way but then it just felt good as he slid deeper and deeper into my hot quivering pussy. I could feel myself stretching to accommodate him but it felt wonderful. He filled me up so much I felt really full but still deeper he went until the sensation was intensely tingly and I felt him push into the end of my channel and felt his hips against mine."I didn't think it would fit," I smiled."You're perfect. You are squeezing me so tight. Honestly I don't know how long I can last.""Don't come," I pleaded, starting to rock my hips, eager to fuck him. "I want to get to feel you for a while.""You like my cock?" he asked with a wicked smirk."Oh yes..." I moaned, humping faster. "I've wanted it for so long.""Little sisters aren't supposed to want their big brother’s cock," he teased."Big brothers aren't supposed to be so sexy," was my reply."Is that why you want me?”"That and your huge cock," I smiled.He groaned and started to pump in and out of me, faster. "I love it when you talk like that.""I love your cock it's so big and it feels so right inside me...I want you to fuck me every time I get horny and lately I'm horny for you all the time!""Oh God. Oh....!!" he gasped and then tensed up. He let out a shaky moan and I felt a warm rush. I knew he'd just come in me.He pulled out and started to apologize profusely, then said it was my fault for turning him on.I lectured him for a bit and told him if I got pregnant he'd have to take responsibility."Whether I wanted to keep it or not you'd have to be there for me,” I said. "Plus I didn't get to come."Well, I think I can fix that," he said.He had me stand up over him and he licked and sucked my pussy and clit until I was gushing and shaking. Then he guided me down straddling him and sinking onto his erection. I slid down on it until I had taken it all inside me. Then I began to move, bouncing up and down on Ryan’s hard cock."Oh god..It's so..It's so.." I gasped out breathlessly."What?""Good," I moaned, as I fucked him, feeling his most private part slide along my inner walls with slick warm friction. I wanted him to always be inside me and never ever take it out."Yes...Yes....Fuck me...." he chanted. "Fuck my cock...take me in you..."I held onto his shoulders and humped against him eagerly. He reached between us and rubbed my button with his thumb as I rode his long horny cock."I'm gonna come," he groaned.I slid off his cock and he stroked it a few times before it twitched and he began to spurt his hot thick white come all over my taut belly and firm thighs. Seeing it shoot out of him like that was the most erotic thing I could imagine.He used one hand to keep stroking himself and the other to plunge two fingers in me and finger me quickly and smoothly, his fingers pumping me and rubbing my g-spot hard until I began to cry out loudly. My inner muscles clenched and melted like butter and I came, gasping bucking and moaning, sending my juices running down his hand.When I was done he took his fingers out of me and licked them clean. In turn I scooped up some of his come from my skin and popped it into my mouth, tasting it."Do you like it?" he asked.I nodded."There's more where that came from.""What do you mean?" I asked coyly."Let's go to your room and I'll show you."In my room he had me kneel by my bed. He stood over me, stepping out of his jeans and boxers and kicking them aside then taking off his shirt.. The part of him that I was getting very familiar with lately was now free, bobbing in my face. I knew what he wanted me to do so I started to lick it. He cupped my head in his hands and sighed."That's it, baby girl. Lick my cock. See how hard it is for you?"It was very hard and getting harder as I traced the veins with my tongue and rolled my tongue around the head."Suck it," he breathed out, thrusting it in my mouth. I sucked it into my mouth and began to slide my mouth up and down it. I looked up at him and his aroused expression made me cream down my thighs."Fuck I can't believe you're sucking my cock and you like it," he hissed, pumping my face."I love it," I said and carried on fucking him with my mouth. He put one of my hands on his balls and showed me how to fondle them while I sucked and slobbered on his cock."Oh, I'm close. Do you want it in your mouth?""Mmmhm," I said.“You're going to swallow my load for me?""MMM!" I moaned.Seconds later I felt a big warm gush fill my mouth and I swallowed but gush after gush came and it ran down my throat and face as I struggled to take it all. I wondered I'd he came this much inside my pussy, if so I was knocked up for sure.When he'd finally given me his last squirts and I'd sucked him clean he had me lay.down on the bed and he ate and tongue fucked me to a stunning orgasm. When I finally stopped shaking he lay down next to me."I want more," I said. “But we’re out of time. Everyone will be home soon.”"Let's do it tomorrow,” he suggested. “After school."I nodded eagerly and smiled to show my approval."Every day after school?" he asked hopefully."Yes. But if you come in me again you're toast!" I said teasingly.He laughed. "Got it."We had sex every day until Ryan went off to college and then we had to bump it down to three times a week because he had classes and homework and I was having a busy Junior year what with joining the dance team and yearbook. Neither of us really felt the need to see anyone else because there just wasn’t the same intimacy or thrill. I never did get pregnant, thankfully, but Ryan and I love to toy with the idea of knocking me up with his baby. We decided maybe after I graduated college we’d try it.
