This all started the summer I turned seventeen. My older sister, Karen, was home from college for the summer. Karen was nineteen and had been away at school for awhile, so at first it seemed weird to be living with her again. Karen and I had always gotten along alright, typical brother and sister stuff, but we were totally different types of people. I'm a tall, skinny kid, kinda quiet and shy. I have a few close friends at school, and I've even had a couple of girlfriends, but definitely no major relationships, and I'm certainly far from experienced in the sex department. Karen, on the other hand, is more or less my exact opposite--outgoing, extremely social and friendly. When she was in high school Karen was a total party machine--Week nights, weekends, whenever. She'd always had tons of different boyfriends and was really popular. In fact, she was such a wild child that I think my parents were pretty relieved to send her off to college. Also, although being her brother I'd never really noticed it, everyone at school (at least all the guys) thought Karen was totally hot: shoulder length natural honey blonde hair, full, pouty lips, blue eyes, large, firm breasts, a tight curved ass and legs to die for. She tanned year round, either laying out (in the summer) or at a tanning booth (in the winter) so year round she had a perfect complexion. Yeah, my sister was hot, and she knew it. She got a kick out of teasing all the guys who were constantly checking her out, flirting with them and driving them crazy. Whenever any of my friends from school would come over to the house Karen would really put on a class act, wearing her sluttiest outfits, super short skirts, virtually non-existent tops that showed off her cleavage really well. She would "accidentally" drop something and bend down really slowly right in front of them until her ass was practically totally exposed, or lean down to talk to them and show plenty of cleavage as her top opened. This drove my friends wild, but they did seem to visit a lot.
Anyway, this particular summer when Karen came home she seemed different--still totally hot, with the party girl attitude, but different around me, friendlier somehow. The moment she walked in the door, before she even tried to find mom and dad, she ran over to me and gave me a big hug.
"Hey Brian, long time no see! Did you miss me?"
I was a little taken aback by this but managed to mumble, "Yeah, I guess so."
She laughed and then stepped back and said, "Hey check it out, you like it? I just had it done a month ago." Karen pulled up her top a little to expose her stomach and a nice gold bellybutton ring.
"Yeah, it's cool. Mom and dad'll probably freak, though."
Again that low, throaty laugh. "Who says they have to know?" Still laughing, she walked into the kitchen.
Things were pretty normal for the first few weeks of summer. I'd gotten a part time job at a nearby supermarket and Karen was out with friends a lot so we only saw each other in passing. The only thing that took a little getting used to was having to share a bathroom again. Karen wasn't exactly the neatest person and our bathroom was always cluttered with "girl stuff": makeup scattered all over, panties, bras, even lingerie. One day I found a bright red thong lying on the floor in front of the clothes hamper. Absent-mindedly I picked the thong up, intending to toss it into the hamper when I noticed a dark spot in the crotch area. I fingered it and it was still slightly damp. Shit! My sister must have just barely taken these off! Quickly shutting the bathroom door all the way, I raised the thong to my face and sniffed it, inhaling deeply. The rich, musky aroma was unmistakable and my cock stiffened immediately in response to the intoxicating scent. Just then I heard someone coming up the stairs and then Karen saying, "Brian, are you in there? Hurry up, I really gotta pee." I froze, the thong still raised to my face. Damn, what was I thinking, sniffing my own sister's panties and getting turned on by it? What the hell was wrong with me?
After a moment or two I managed to reply, " I"ll be out in a second." Blushing, I tossed my sister's thong into the hamper and then flushed the toilet, ran some water and pretended to wash up long enough to allow my hard on to dwindle.
As soon as I opened the door, Karen shot past me into the bathroom. "About time, I really gotta go." As she passed me her hair brushed against my face and I caught just a slight hint of musky perfume. My cock twitched in response and I quickly closed the door and hurried downstairs. As I went, I couldn't help wondering about just how Karen got that damp spot on her thong, and just thinking about it, about her, was getting me aroused. What the hell was going on with me? I never thought of myself as a real pervert (no more so than any other typical teenager with raging hormones anyway) but here I was getting a throbbing hard on at the sight of my sister's panties and the scent of her perfume. I tried to dismiss it as being simple horniness, but still my thoughts lingered on my sister for a long time.
Everything changed when mom and dad went away for their annual week's vacation. Since Karen was the oldest, they informed us, they would be leaving her in charge. Needless to say, Karen enjoyed this immensely, and I had to endure a lot of teasing about her being the boss and comments like, "Ok Brian, you better do what I say, remember who's in charge around here." Karen also took advantage of this opportunity to turn our house into party central almost as soon as mom and dad's car left the driveway. She partied hard for two days (and nights) in a row, and there was never any shortage of people (mostly guys, I noticed) who were willing to party with her. Each night ended the same way: My sister, drunk off her ass and already half naked, stumbling upstairs to her bedroom with whichever lucky guy she'd chosen to be her boy toy of the evening. I would never admit it to myself fully, but in the back of my mind I couldn't help feeling a twinge of jealousy as I watched her stagger up the stairs draped all over some anonymous stud.
Whenever I could, I would help Karen clean up the mess the next day, but because of my work schedule Karen had the house to herself a lot, especially during the day. One day, toward the middle of the week I got off work early (it was around two in the afternoon instead of the usual four). When I pulled into the driveway, I noticed that there was another car there besides Karen's, but I didn't think anything of it, figuring it was just one of Karen's friends. I walked into the house, tossed my keys on the kitchen table, and was just thinking of getting something to eat when I heard a noise from upstairs. Bedsprings were creaking like crazy and i heard Karen moan, "Oh yeah, that's it! right there! oh, fuck!" Shit, Karen was fucking some lucky bastard right now, in the middle of the day. for a moment I stood there, motionless at the foot of the stairs, just listening. then I couldn't resist any longer--I just had to check it out. I kicked off my shoes and crept up the stairs as quietly as I could. Score! Karen's bedroom door was partway ajar. (She obviously wasn't expecting me home for a couple more hours). Sneaking past our shared bathroom, I hid myself behind Karen's partly opened bedroom door as best I could and peeked in. I couldn't believe the sight that greeted me: Karen was on her hands and knees in the middle of her bed, completely naked, getting fucked hard by two guys at once! the guys both looked vaguely familiar and I figured I'd probably seen them at one of Karen's parties. The guy in back, the one with dark hair, was pounding away in Karen's pussy furiously, while the guy in front of her, a blonde, was holding the back of Karen's head with both hands and sliding his large cock in and out of her willing mouth, fucking her face. The room was filled with moist slurping sounds as Karen's dripping snatch engulfed the dark haired guy's cock, his balls slapping against her ass cheeks, her big tits quivering and flopping as her fucked her. Karen pulled away from the blonde's big cock long enough to scream out: "Yeah, that's it! Fuck my wet pussy! Oh, God! Shit! Ahh, make me cum!!"
I couldn't believe it. This was so incredibly hot! My cock was so hard that it was practically tenting out my jeans. I was afraid my zipper was gonna explode. The guy behind Karen really picked up the pace then, slamming his cock into her as hard and fast as he could, pulling out the entire length and then driving it into her until his balls slapped against her red ass cheeks, making her scream and moan as she continued to deep throat the blonde in front of her.
"Fuck man, this bitch is awesome," The dark haired guy grunted as he pummelled my sister's sweet pussy.
"Yeah dude, she's really into it," The blonde replied, face fucking Karen until she gagged and his balls were pressed up against her chin.
Karen moaned deeply, then pulled away from blondie's big cock and gasped out, "Yeah, it's so fuckin' good! Wait, I want you both to fuck me at the same time. I want a cock in my ass and pussy!"
The guys looked at each other for a second, then the the blonde said, "For real? You wanna get double stuffed?"
"Fuck yeah I do!" Karen panted. "Here, lie down on your back."
It was as they switched positions that I made my crucial mistake. I was so caught up in the action going on in front of me that I forgot that I was only partially hidden by the bedroom door. As Karen swung around and impaled her wet pussy on blondie's hard cock, she was facing directly toward the doorway. For just a moment, our eyes locked. She got this huge grin on her face and, still staring directly at me , she shoved herself down and took blondie's entire cock deep into herself in one motion. Fuck! I was caught! I quickly ducked back completely behind the door, but I knew it was far too late for that. As I stood there, torn between shock and incredible feelings of lust, I heard Karen say, "Mmmm, yeah, now shove your big dick up my tight little asshole! Yeah, fuck both my holes!" This pushed me over the edge. I couldn't take anymore, my cock was so hard I was afraid I was gonna cum in my jeans in another second. I rushed to my room, shutting the door behind me as quietly as I could, I ripped off my clothes in a frenzy and, lying down on the bed completely naked jacked my rock hard prick as I continued to listen to my sister getting fucked just down the hall:
"Oh yeah,uhhh, that feels so good, so full! Harder! unnh!"
"Dude, her ass is so fuckin' tight! Feels great!"
Long moments of panting and wet sucking sounds.
"Oh, man, I can't last much longer, I"m gonna nut!"
"Me too, shit, it's too fuckin' good. Uuuunh, fuck, I'm gonna cum!!"
"Yeah, fuckin cum inside me! Shoot that shit deep in my ass and pussy! Do it!"
"MMMM, UNNHHH! Yeah, fuck!!"
For a long while everything was quiet except for the sounds of harsh panting and low, ragged breathing. My hand was a blur on my cock by this time, and I felt ready to explode. I froze as I heard the sound of voices in the hallway:
"Shit Karen, that was awesome! Thanks a lot!"
"Yeah, thanks, that totally rocked!"
"Anytime guys. You should come over more often!" The sound of my sister's laughter.
"You know we will now for sure! We'll call soon. I wanna get a chance at your sweet ass next time!"
"No problem, whenever you want, Gary." Again, her soft chuckle.
"Well, we gotta take off, practice this afternoon."
"K, see ya later. Call me."
"You know it!"
Then the fading sound of footsteps on the stairs, the slamming of the front door, and they were gone. Man, I just had to bust a nut. I resumed jacking at a frantic pace. Yeah, so close, I know I'm gonna shoot a huge load, almost there. . .
My bedroom door swung open. Karen stood in the doorway, naked, her large nipples rock hard, a slight sheen of perspiration glistening all over her body and a mixture of cum and her own pussy juices running down the inside of her legs. "Jesus, Karen, what the hell are you doing!?!" I grabbed frantically for my blankets and threw them over my lower half. It was a somewhat useless gesture, though, since my cock made a tent out of those blankets in a major way.
She looked at me with an arrogant little smirk on her face. "Did you like it?"
"What?!? Wadda you mean?" This has to be a dream, I thought to myself. This can't really be happening. This hot-ass slut goddess standing in my bedroom doorway, the picture of every teen male's fantasy, and she's my fucking sister!
"Did you like it?"
"Shit Karen, this is too--"
She stepped up beside the bed and with a single motion ripped the blanket away from me, leaving my exposed and rigid manhood sticking straight up. Karen looked me and chuckled. "Yeah, you liked it. You loved watching your big sister get stuffed full of hard cock. You loved watching me suck dick and get plowed in the ass, didn't you, Brian?"
At this point I was in such shock that all I could do was make strangled noises in the back of my throat and gaze at her helplessly. My raging hard on said it all, however. Karen slowly swung her leg over the side of the bed and squatted directly over my face, her dripping pussy inches from my mouth. "Be a good brother and lick my pussy and ass clean, Brian, suck my cunt and make me cum all over your face. Lick me!" She shoved he pussy against my open mouth, grinding down on me, smearing a mixture of cum and sweet pussy juice all over my face. Part of me knew that this was wrong, that incest was wrong, but by this point I was so crazed with lust that I would do anything. Reaching up, I grasped Karen's hips and pulled her down even farther until she was almost smothering me with her beautiful pussy. I licked and sucked every inch of her hole, tasting her, exploring the folds of her cunt lips with the tip of my tongue, tongue fucking her, sticking my tongue as deeply inside her as I could, tasting the sweet tang of her own juices mingled with the faintly salty flavor of the spunk that was dripping from her holes.
"Oh yeah, little bro, just like that, clean my pussy real good. I knew you wanted this." She ground her crotch against my face hard as I continued to lap, sucking all of her juices into my mouth, tasting the core of her as I flicked my tongue against her swollen clit as hard as I could. "Oh shit, oh fuck yeah bro! That's it, make your big sister cum!!" Karen squealed and smashed her crotch against my face as she came, squirting hot sticky pussy juices all over my face and open mouth. "Oh yeah, Brian, that was really nice. Clean up my asshole now and you'll get your reward." I obeyed eagerly, tonguing her beautful tight butthole, lapping all around it, plunging the tip of my tongue deep inside, sucking out all of the jizz that had been shot into her and gulping it down. "Mmmmm, that feels so good Brian, you nasty little boy, sucking cum out of your big sister's asshole," Karen moaned. "That's it, stick your tongue in real deep, make sure you get it all. " After awhile Karen stood up and smiled at me. "You did a real good job, little bro. You've earned your reward. Ok, go ahead and spread your legs wide apart." I did so and Karen crawled between my legs. I gasped with pleasure as I felt Karen's warm hand close around my dick and begin slowly pumping up and down. "Mmmmh, doesn't that feel good Brian? You like the feeling of your big sister's hand stroking your hard cock? Do you?"
"Yes, yes!" I stammered.
"Yeah, I thought so. Then you're gonna love this." Karen ran the tip of her tongue all around the head of my cock, licking at the piss slit and tasting the pre-cum that was flowing out of me as she continued to slowly pump up and down with her hand.
I moaned deeply and arched my back. "Ohhh, God, Karen that feels so good!!"
Karen glanced up at me again with that arrogant smirk on her face. "What do you want little brother? Do you want to cum? Do you want to feel my lips around your cock as you shoot your load into my mouth?"
Weakly I gasped out, "Yes."
She smirked at me again, her hand wrapped tightly around my now pulsing dick, her mouth inches from my engorged cockhead. "Beg for it, bro. I wanna hear you beg your big sister to suck your cock."
I couldn't help myself. "Please Karen, please, I'm begging for it, please suck my dick, make me cum."
She chuckled. "Good boy." I gasped as I felt the warm wetness of her lips engulfing the head of my cock, moving down my shaft, massaging it with her tongue, slowly taking more and more until my cock was buried in the wet heat of her throat and my sister's nose was mashed against my pubes. She slowly and gently squeezed my balls with one hand as she slurped on my cock, deepthroating it and then releasing, sucking only the head, moving down slowly and teasingly. It felt so incredible, and I knew I couldn't last much longer. Looking down at my sister's head bobbing up and down on my hard shaft I felt my ball sac tighten and my toes begin to curl.
"Oh, shit, yeah, oh god, Karen, I'm gonna cum!!!" Karen took my cock deep into her throat, swallowing reflexively as I shot blast after blast of hot cum into her mouth. Finally I lay back, panting for breath, my eyes half closed in delirious oblivion. My sister crawled slowly up my prone body, dragging her hardened nipples against my chest,sliding her beautiful tits against me. Our lips met in a long, delicious kiss, and as Karen's tongue slid into my mouth I tasted the salty bitter flavor of my own cum.
"Did that feel good, Brian?"
"Oh, shit, Karen, that was the best orgasm I've ever had!"
She smiled. "Yeah, well it sure as hell won't be the last one. We've got all summer, and I have definite plans for you, little brother."
I looked up at her with a puzzled expression. "What do you mean?"
She just giggled and waggled her eyebrows at me. "If you're a good boy, maybe you'll find out."
She slid off of me and stood up. "Stay right here, don't move, I'll be back in a second." Watching my sister's perfectly tight, round little ass bounce as she walked out of the room, I felt my cock stir and come to life again, stiffening in appreciation of the sight. I lay there in a daze, unable to believe what had just happened. After a few minutes, Karen came back holding a couple of lengths of kitchen twine in her hand and smiling wickedly.
"Woah, wait a minute, what are gonna do with that?" I asked.
Karen just laughed. "Don't worry Brian, I promise, you'll love this game."
Before I could quite register what was going on, my sister had grasped both my hands and tied them securely to either side of the headboard bedposts. I lay there on my back, hands lashed tightly above my head, helpless and under my sister's complete control. my cock throbbed with eager anticipation even as in another, more rational part of my mind I was a bit scared. Karen reached down and squeezed my erection lightly. "Hmmm, it looks like you missed me while I was gone." Then she glanced up at me. "You look good this way Brian, bondage agrees with you."She crawled up my body until she straddled my chest, her beautiful, firm breasts swaying inches from my face. "Oooh, Brian, when you ate me out it made me sooo wet, " she whispered in my ear. She wiggled two fingers into her wet pussy and then slowly, seductively swirled her fingertips around her hardened nipples, smearing them with her own juices. "My nipples are so hard, Brian. Do you like my tits? Do you want to suck them?" She continued to knead and caress those firm mounds now only inches from my face, tweaking her nipples, tugging on them.
By this time I was in an absolute frenzy of desire. Karen's dirty talk was driving me crazy ; all I could think about was how much I wanted her body, how much I wanted to give her pleasure, to obey her every whim. "Yes! God yes, I wanna suck your tits so bad, Karen, please!" I panted.
Again that soft, throaty chuckle. "Good boy, you learn fast. Go ahead Brian, suck your big sister's titties, make me feel good." She leaned forward and pressed her tits against my face and slid them back and forth as I sucked first one then the other hard nipple into my mouth, swirling my tongue around it, tasting the musky sweet flavor of her pussy. After a few minutes of this Karen pulled back slightly, positioning herself so that she was straddling my waist, holding her pussy just above my hard and throbbing dick. "What else do you want, little brother? Do you want to fuck me? do you want to feel your sister's hot, wet pussy sliding up and down your shaft, squeezing it, making you cum? Is that what you want?" Karen whispered.
"GOD!! YES, YES!!" Tugging uselessly at my restraints, I bucked with my hips trying desperately to plunge my cock into her hole.
Smiling, Karen slapped me gently across the face. "Who's in control here?" she demanded.
"You are, Karen."
"That's right. You'll do whatever I want, whenever I want, won't you little brother?"
"Yes, yes, I swear Karen, I'll do anything you want, just please fuck me."
She laughed softly. "That's better, Brian. I love to hear you beg, it turns me on. Say, 'Mistress Karen, please fuck me and make me cum.'" I hesitated for a moment, staring up at her. "Beg for what you want little bro, and I'll give it to you."
I was so turned on by Karen's aggressiveness, her total dominance, that I would have done anything she said. "M-mistress Karen, uh, please fuck me and, uh, and make me cum," I stammered in a low whisper.
"Mmmmm, that's a good little slave." Karen slowly eased herself down onto my cock, sliding down my shaft until I was completely buried in her hot, wet tunnel. The sensation was exquisite and I moaned deep in the back of my throat, trying desperately to keep from cummming right then and there. Karen whimpered sofly and began sliding up and down on my cock , riding me faster and faster until she was slamming up and down, balancing herself with both hands pressed against my chest as she fucked me, her ass grinding down against my balls with every stroke. "Ohhh, Brian, that feels sooo good!!" she panted. "YEAH, FUCK ME!! You're fucking your own sister you nasty little slut! Do you like it? Does it feel good?"
I was totally in bliss, the feeling of my sister's tight slippery twat riding me, devouring my cock, was amazing. "Yeah, god yeah! Oh shit Karen fuck me harder! please!"
Karen was riding me furiously now, impaling herself on my hard shaft as deeply as she could with every stroke, panting, her head thrown back, her huge tits quivering as she fuicked me. "Yeah little brother, that's so good, so fuckin' good! Make me cum, uuunhh, yeah, oh god, oh shit, I'M CUMMING!!!" With a scream she thrust down on me completely and I could feel the walls of her pussy contracting as she came, flexing around my cock, milking it.
"Oh Fuck, Karen, I can't hold back, uuuhn, AHHH! I'm gonna cum!"
Karen leapt off of me and, grabbing my still pistoning cock with her hand, she aimed it directly at her chest. "Yeah bro, shoot that hot load, I wanna watch you shoot your jizz all over my big titties!" She stroked my cock twice and I was gone. "AAAAHHH!" Cum erupted from my cockhead in three long spurts, coating my sister's tits, dripping from her nipples. I fell back against the bed, hanging limply against my restraints, exhausted, totally spent. Karen rubbed my cum all over her breasts, massaging it into them. Using both hands she then scooped up all of my cum from her chest and lapped it from her fingers, swallowing every drop.
"Mmmm, you taste delicious little brother." She untied my wrists and lay down beside me, snuggling close. Kissing me on the cheek she whispered, "Better rest up Brian, this is just the beginnning. Remember, you promised, 'anything I want,' right?"
