Looking back, it was probably the craziest thing I've ever done. But at the time it didn't seem crazy at all. At the time it was like I just couldn't help myself. I'm talking about the incredible week I spent with my little sister, Stacy.
I had never been attracted to her when I was a kid; I mean she was my sister for God's sake. Growing up, we had a very typical relationship. We fought all the time, annoyed each other, and most of the time I thought she was a snot-nosed little twerp. But that was before the summer when she came back from her first year away at college. After that, a lot of things changed.
I remember that she had really started to come into her own during her senior year in high school. She started to dress like a woman instead of a tomboy, and she was wearing makeup, too. Not to mention that she had really grown into her body. I remember noticing how she looked at her graduation party in the bathing suit she was wearing. She had become a very shapely young woman. She had long, tanned legs, a tiny waist, and a tight behind. I have to admit that I caught myself staring at her more than once that day. I even had a few of my friends mention how large her tits had gotten. They were quite large, and she apparently didn't mind showing them off, either. Her bikini wasn't exactly something I'd call conservative. I just told my friends they'd better leave her alone. They chided me, saying, "looks like he's saving her all for himself, boys! It's okay, he's just trying to keep it in the family!"
They were just kidding, but if they only knew....
It was a year later that she was returning from her freshman year at the University of Miami. It was my job to pick her up from the airport, since our parents were out of town for a week. I waited impatiently at the coffee shop right outside the terminal gate until I heard a voice over the intercom say her flight was deboarding. When I saw her coming down the terminal I couldn't believe my eyes. I guess my surprise was obvious, because she gave me a sly smile in return. It's amazing what a year in Miami can do to a girl. She looked taller, leaner, and, well...sexier.
She had blossomed even from the girl I remembered at the graduation party. Her legs were still long and tan, but they were toned now, too. They looked great in the Daisy Dukes she was wearing. Her sandy hair was lighter from the sun and her face was beautiful. She had bright sky blue eyes, thick, pouty lips, and a gorgeous smile. Her little waist was hugged tightly by the pink tank top she was wearing, which was very low-cut, accenting her large, braless breasts. She apparently still had no problem showing them off. They must've been double-D's.
She walked straight up to me, threw her arms around me, and kissed my cheek hard. I could feel her tits pushing against my chest as she did, and it caused my dick to stir a little in my shorts. She slid a leg in between mine, and it pressed into my crotch. I hoped she hadn't felt anything.
"Hey big brother! How the hell are ya?" She smiled a big goofy smile at me and kissed my cheek again.
"I'm great, kiddo, how are you doing?"
"Oh my God, I'm just glad to be home," she sighed.
I smiled at her. "Good. Let's go get your bags and get out of here."
"Lead the way, sir." She hooked her arm in mine. "I'm all yours."
I was caught between happiness and discomfort. I was happy to see her, but I couldn't believe I was looking at my own baby sister the way I was. It was sick, right? But like I said, it was like I couldn't help myself.
We grabbed her luggage at the baggage claim and walked it out to the car. Her pert ass was teasing me as she walked in front of me, but I did my best to hide it. Her shorts were cut so high that the bottoms of her ass cheeks were peeking a little. I guess that's probably an everyday thing in Miami. When she got to the car she dropped her suitcase and knelt down to dig through it. I stood over her opening the trunk and I couldn't help but look down at her large breasts, which were barely contained by her tank top. My dick stirred again. I was disgusted with myself.
"Jesus, Stacy, don't you think you ought to have some...support?"
She gave me a confused smile, still rooting through her bag. "What are you talking about?"
I didn't say anything; I just motioned to her chest. Her boobs were practically fully exposed, popping out in front of God and everyone. She yanked her hand out of her bag, grasping a white lace bra.
"Yes, daddy," she waved the bra in my face. "Anything else I should or shouldn't be wearing?" She grinned, giggling at my obvious embarrassment. "These things are just way too uncomfortable to fly in. Besides, don't act like you didn't like what you saw."
"What?" I said, shocked, and trying not to make it too obvious that I actually did like what I saw. "What's that supposed to mean?"
"Oh come on, Jimmy," she tossed the suitcase into the trunk and closed it. "You may be my big brother, but you're still a guy, and tits do the same thing to you as every other guy in the world." She smiled that sly smile at me again. "Especially big ol' knockers like these!" She laughed and grasped her big tits and started jiggling them at me. I did my best to try and hide my stirring cock and act disgusted. I couldn't believe she was acting like this.
"Knock it off, sis!" I stammered, my eyes locked on her luscious titties.
"Besides," she whispered, pulling me close enough to touch my ear with her sultry lips. "You don't really hide it too well, if you know what I mean." She reached down and put her hand on my cock through my shorts, lightly massaging it with her fingertips. My face must have turned bright red. She had felt my dick at the terminal gate. I didn't know what to say.
"I-I don't know what you're talking about."
"Oh, stop, Jimmy. It's nothing to be embarrassed about. I have nice tits. If I was in your shoes I'd probably get a hard-on looking at them too!" She laughed out loud.
"Fuck, Stacy, just get in the car and let's go."
"Yes, sir!" She laughed and jumped in the passenger seat. I stood at the rear of the car for a few seconds trying to gather my bearing. Come on, man, she's your sister for Christsake! Get a hold of yourself.
I opened the door and slid into the driver's seat just in time to see her slipping the straps of her tank top over the white lace. She had deftly managed to slip the bra on before I could get into the car, somewhat to my dismay.
"That better?" She cooed, batting her eyelashes.
I shook my head with the slightest smile I could manage and drove us home.
When we got home Stacy said the first thing she had to do was get out of the clothes she was wearing. Then she joked and apologized for mentioning such things around me. "Wouldn't want your dick to start getting hard over your little sis again, would we?" She winked and ran upstairs to her room. I couldn't believe how forward she was. It was like she had no shame. As embarrassed as I was about the whole thing, it didn't seem to bother her at all. She seemed to be relishing the fact that her older brother was lusting after her. Actually, it seemed to encourage her. It was like the more I got turned on, the harder she worked to keep me hot and bothered.
While Stacy was upstairs changing, I decided I needed a dip in the pool. I hoped the cool water would help ease my throbbing cock down. I went upstairs to my room, just down the hall from Stacy's. I pulled my clothes off and stood in my room naked. I couldn't help but imagine my little sister doing the same thing right down the hall. I pictured her unhooking her bra and freeing her enormous breasts, then slithering out of her panties. I imagined her lying down on her bed and spreading her legs wide, sliding her middle finger up and down her wet slit. I let my hand slide down my rock hard cock, gripping the base, and squeezing a small stream of cum out the tip. It felt dirty and wrong to think of my sister like this, but I think that's why it turned me on so much. I began stroking myself faster. I imagined it was Stacy's hand stroking me, then her mouth and tongue, then-
"Hey Jimmy, you in there?" Stacy was knocking at the door. "I'm going down to the pool and I want to show you my new swimsuit."
Shit, I thought. Now she's going to the pool, too. I'm never going to get rid of this hard-on.
"Uh...yeah...hold on a minute. I'll be right out."
With that the door flew open and in walked my sister wearing the skimpiest bikini I'd ever seen. It literally left nothing to the imagination. Every inch of every curve of her luscious body was completely on display, right down to the hard nipples poking through her top. I could even see that her pubic hair was shaved into a racing stripe right above her clit. It was like the suit was painted on her nude body. It was incredible. And there I stood in all my naked glory, my hard dick in my hand, and my eyes wide with shock. Shock from being caught jacking off, and shock from seeing my sister practically nude right in front of me.
"Oops," she said with a giggle. "Is this a bad time?" She sashayed into the room and plopped down on my bed. It was apparent she didn't really care whether or not it was a bad time.
"Holy Shit," I said as I managed to pick my jaw up off the floor and regain control of most of my motor functions. I frivolously scrambled for anything I could cover up with while Stacy rolled on the bed with laughter. There was a towel on top of my dresser, so I snatched it and threw it around my waist as quickly as I could, my long erection making a huge tent in the front of it. I guess at that point it didn't really matter what she saw anymore.
"Jesus Christ, Stacy, what the hell's the matter with you?" I fumed. She was still laughing. "You don't just go around barging into people's rooms like that!"
"Oh, stop it." She said. She laid on her stomach on my bed, propping herself up with her elbows. Her beautiful tits were popping out of her bikini, and I could now see that the bikini bottom was a thong. "You're just mad because you got caught jerkin' your gherkin."
"I was not!"
"Oh really?" She pointed toward my large erection that was now poking through the gap where the towel was wrapped around me. My first instinct was to try and cover it back up, but I didn't. My embarrassment was fading. Besides, she didn't seem to care, so why should I? What was the big deal? So I got caught jerking off. Chicks do that stuff all the time, too right? There was no use trying to deny it. Still, the naughtiness of the situation made me horny as hell. My 8-inch cock was pulsing now, keeping a steady beat with the racing of my heart. It was so hard it almost hurt.
"Okay, so I was jacking off. So what? That's exactly the reason you shouldn't be just walking into somebody's room when the door is closed!" I crossed my arms and stared at her sexy figure. My cock was aching to be stroked, and seeing her lying on my bed practically naked was definitely not helping the situation.
"Were you thinking about me?" she asked with a devilish grin.
"What?" I exclaimed, as if the question was ludicrous. "What the hell kind of question is that?"
"It's okay if you were, Jimmy. It wouldn't bother me."
I hesitated, unsure of how to answer. I looked at her for a minute and decided to risk it. She had been playing some sort of seductive game ever since she'd been home. I wasn't sure where it was going, but right now I was definitely in the mood to play along.
"Okay fine. Yeah I was thinking about you."
"I knew it!" She giggled and kicked her feet. I laughed, a little relieved that the embarrassment of the situation seemed to be fading.
"Well how could you blame me? I mean...you've been walking around with your tits hanging out ever since you got off the plane."
She laughed again. "You mean these?" She rolled onto her back and pulled her bikini top to the sides, revealing the most gorgeous set of tits I'd ever laid eyes on. She cupped them in her palms and pushed them together, giggling like a little girl. "Do you want me to hold them like this while you finish jacking off?" Just the sight of her big breasts and the thought of staring at them while I jacked off were almost enough to make me cum right there. She arched her back and began caressing them and rolling her nipples between her fingers. "Ooh, come on, baby. Stick your dick between my tits and cum all over my face!" she moaned. I did my best to keep my composure, but this was too much for me to take. My dick was going to explode if I didn't do something soon.
"Stacy, this is too fucking weird. I can't deal with this. I think you should leave."
She frowned at me. "Oh come on, Jimmy, relax. I'm just fucking with you. Geez, take a joke, will ya?" She rolled over onto her stomach again and put her tits back into her top. "The only reason I even came in here was to show you my new swimsuit. What do you think?" She struck a pose, arching her back and pushing her tits together with her arms. I wanted to tell her that I wanted to rip the suit off her and fuck her right there, but I couldn't.
"I think you're acting really weird, Stacy! I mean...I'm standing here naked in front of you and it's like you don't even care!"
She rolled her eyes at me. "Oh come on, Jimmy, so you're naked. Who cares? It's not like I've never seen a penis before. Every guy has one, dear. It's not a big deal." Then her eyes fixed on my hardness, and she hesitated for a moment. "Although," she paused, "yours is somewhat of a big deal, isn't it?" She sat up and moved herself to the edge of the bed, leaning forward and staring hard at my cock. She motioned for me. "Come here."
I hesitated for a moment, dismissing the thought that she was my sister as quickly as it had come. I walked to the edge of the bed and Stacy grabbed the towel and pulled it off my body. My cock was throbbing, dangling an inch of front of her face. My heart raced. She examined it like it was some strange, foreign object.
"Oh my God, Jimmy. You're dick is huge. I've never seen one this big before." She reached up and grabbed ahold of the shaft.
I melted. Just her touch made my whole body tingle. My knees felt like they were going to buckle. I let out a low groan as a few drops of cum leaked out onto her hand. "Ooh, I'm sorry," she whispered with a slight laugh. She stuck her tongue out and licked the cum from her fingers, her lips brushing my cock and making me insane. "I didn't mean to grab it like that, but...I just couldn't help myself."
"What do you mean?" I asked, practically in a daze and consumed by lust.
"Well it's just so...big. I've never seen anything like it." She sat back on the bed and parted her thighs. "To be honest, it really...turned me on." She slowly slid her hand beneath the low waistband of her bikini bottom while her eyes remained focused on my pulsing member. "Oh yeah...I'm wet." She let out a soft moan as her fingers began exploring beneath her swimsuit. I couldn't believe what was happening. I was standing naked in front of my incredibly hot sister, watching her masturbate while she was stroking my rock-hard cock. Suddenly, she leaned forward and slid the tip of my dick into her mouth. The warm, wet sensation of her tongue sliding over my dick was like pure heaven. Slowly, she began to work her lips and tongue over my cock, letting out muffled moans as her other hand moved rapidly beneath her swimsuit.
"Oh, Stacy," I groaned, watching the first few inches of my hardness sliding in and out of my baby sister's mouth. "What are we doing?" I reached down and put my hands on her head, running my fingers through her hair while she sucked me.
She took my dick out of her mouth and threw her head back, moaning violently. Her right hand was buried deep in her bikini bottom, her fingers thrusting in and out of her sopping wet pussy. She had sprung back so hard that her tits had popped out of her swimsuit again. I looked down and saw the hard nipples poking out at me and couldn't resist anymore. I pushed her down flat on her back and pulled the bikini top over her head, simultaneously burying my face in her beautiful titties. I slurped and sucked and licked her nipples while she brought herself to orgasm with her fingers.
Once she finished, she didn't say a word. She jumped off the bed and slid her bikini bottoms down to her ankles, revealing the most beautiful pussy I'd ever seen. She grabbed my shoulders and pushed me down on my back on the bed. She then jumped on top of me and moved forward, straddling my face. Her open pussy lips pressed against my mouth. I began thrusting my tongue in and out, drinking her sex as it flowed into my mouth. She leaned back and moaned, grinding her hips in rhythm with my licking. She grabbed ahold of her huge tits and squeezed them hard while I fucked her with my tongue.
I couldn't take it anymore. She had been teasing me long enough. I reached up and took her by the waist, lifting her up and sliding out from underneath her. I then turned around so I was directly behind her. She bent over forward and spread her legs, inviting me to thrust my cock into her. I positioned myself behind her on the bed and began to slide the head of my dick up and down her pussy lips. She moaned deeply.
"Oh God, Jimmy put it in. Fuck me hard with that huge dick of yours."
Without any further hesitation I thrust my hips forward and buried my cock deep inside her. I was instantly euphoric. I began thrusting, slowly at first, watching her huge tits bounce each time I slid my cock forward. She was practically screaming now.
"Oh my God! Fuck me! Fuck me harder!" she screamed.
I could feel the pressure building in my cock. I wasn't going to last much longer. I let go and started fucking her hard. I put my hands on her hips and looked down at her tight ass while my dick disappeared again and again into her pussy. I pulled her body toward me and then pushed her back out, pumping her sopping pussy until my dick was ready to explode.
"Oh God I'm gonna cum!" I groaned
"Don't Stop!" she screamed. "Oh my God I'm cumming too!"
I felt the muscles of her pussy contract and my cock exploded like never before. I kept pumping into her from behind as I spurted load after load of hot semen into her pussy for what seemed like forever. It was the longest orgasm of my life. Stacy fell down to her face on the bed, breathless. She told me later that the orgasm had been so strong that she'd actually blacked out for a moment.
When my orgasm finally subsided I collapsed on top of her. She turned over and pressed her lips to mine.
"That was the most incredible sex I've ever had," she said.
"Yeah, me too." We both laughed and laid in bed tangled in each other's nakedness for a while.
We spent the whole week that our parents were away having the best sex of our lives. We must've sucked and fucked each other fifty times in that week. After that we carried on just like normal. But every now and then, when we get together after a long period of time, we look at each other and remember that first time. We're both married and have moved on with our lives now, but I think the longing is still there when we see each other. It is for me, at least. After all, how many people can say the best fuck they ever had was their little sister?
