CHAPTER ONE

Cyndi had been driving me crazy all week. My younger sister, I had to admit, was one of the sexiest women I had ever known, and she wasnt modest about showing off her sexiness. She also wasnt very modest about showing off her body, which was incredible. Cyndis tits were large and smoothly formed, some of the nicest tits I could imagine. And there wasnt a time I could recall when Id seen Cyndis breasts without firm, erect nipples. She was always turned on it seemed. Id had plenty of time to see Cyndis nipples lately. Our parents were out of town for two weeks and Cyndi was taking advantage of her new freedom to be as immodest as possible. She pranced through the house with the skimpiest clothes possible, often just a T-shirt and panties, or one of her delightful little bikinis. Her boyfriend Rod had been spending nights over here. Cyndi and Rod shared my parents bedroom and I didnt have any doubts about what went on in there. As a matter of fact, more than a few times I had watched them when they left the curtains open at night. My parents window was plainly visible from the balcony of my room, something Id found out only recently, but something that gave me lots of entertainment since Id come home for the summer. Now that my parents were away, I had to admit I much preferred watching my little sister. Those two were the kinkiest couple Id seen in a long time. They even rivaled me and Megan, though Megan and I did have a pretty wild time of it.

I called Cyndi my little sister, but Im not quite sure why. She was only a year younger than me, eleven months, as a matter of fact and not a whole lot smaller. Her tits certainly werent little at all, and neither where those big sexy blue eyes — Moms eyes. But Cyndis sex drive was the biggest thing all about her. My little sister was the horniest slut Id ever known, even hornier than her big brother!

I had left home to go to college just last September when Cyndi was a senior in high school and a virgin as far as I could tell. But since Id come back for the summer, Id come to realize that my little sister wasnt anything like a virgin, nowadays. On the contrary, she was a much-fucked tramp! Not that I objected — especially since I could see through her window. And Cyndi wasnt just a normal slut. She was kinky! She liked it all ways, and some of them were quite enticing.

Id watched Cyndi get it up the ass several times since our parents left. Rod seemed to love giving it to her that way and whenever they did it, the moans would have kept me awake even if I hadnt been watching. She also liked it doggy-style. Id watched Rod fuck Cyndi from behind more often than theyd done it face-to-face and that was quite often, to be sure. Cyndi also liked having Rod come on her face and her tits. She went wild with desire, rubbing the thick jizz all over her nipples and lips and covering her cheeks with it. She also really got into dressing up for him in leather and high heels most of the time, and once shed even worn a dog-collar, just for effect, since they werent into bondage. And Cyndi wasnt just kinky with Rod. She liked cheating, as well — shed already had three other guys up to my parents room, and not just individually. Get this — shed had two guys up there at one time! I didnt wonder what they did in there! I knew! Naturally, I had watched. At least, as much as I could. Steve and Al had gone up there together one night when Rod was working late — supposedly just to drink. But before long Cyndi was drunk and the two guys had her clothes off and were fucking her from both ends. Steve put his cock up Cyndis ass and Al entered her through her cunt — while Cyndi went crazy with pleasure! I could hear her moans and screams of ecstasy all the way downstairs — so I was duty-bound to watch her! I chuckled to myself as she went at it with them, giving them head, letting both of them eat her out, sharing her tits between them, the whole bit. If Id had any doubts as to what a willing young vixen my little sister was, I gave them up that night. The sight of two cocks pounding into her had convinced me!

Shed also had Rods friend Doug up in my parents room, but she didnt try to hide that fact. Doug didnt have to drink with Cyndi to get her into bed. Cyndi came on to him, and before long they were fucking doggy-style. Cyndi really knew how to seduce a man, and Mom hadnt raised her to let her talents go to waste.

Mostly, though, Cyndi fucked Rod. Every night, and usually in the afternoons. They liked to use the hot tub and the sauna, and sometimes the shower which joined our two rooms. In that big house, there were plenty of places to fuck, and they didnt try to hide what they were doing. Id stumbled upon them fucking in the window seat which overlooked the pool, in the garden, in the attic… they were a swing couple. And Cyndi wasnt just kinky with Rod. She was plenty kinky on her own. After all, she had only met Rod a month ago, and she had several months before that to try out her newfound lack of virginity. She kept a little diary of her lovers, which Id peeked in to once or twice. I felt like a sneak thief, but my little sister fascinated me so much I just couldnt keep myself away!

And Cyndis room was a veritable treasure chest of pleasure.

Cyndi liked dildos — Id found an assortment of them, all enormous, under her pillow. Along with a cache of skin mags, both men and women. They were all very explicit, showing everything. More of the magazines had women in them. I guessed that Cyndi was bi. The thought of Cyndi looking over those magazines and playing with herself till she came was almost too much for me. It made my cock throb to fuck her. And Cyndi also had a vibrator, nice big one with ten speeds. It plugged into the wall socket, so she wouldnt have to worry about running out of batteries when she most needed her fuck. She hid the vibrator in her top drawer, buried under her sexiest underwear. Cyndis panties and bras simply made her drool. She had tight, lacy panties that hid absolutely nothing, and tight demi-bras with under-wire that pushed her tits up and together, accenting her tits deliciously. Even more interesting were her garter belts and fishnet stockings, which she wore when she was really going out to get fucked. Id seen all these things on Cyndi, when I spied on her as she dressed. But more often when she showed them off, bounding through the house with her cavalier attitude about nudity.

My parents were very liberal and didnt try to hide their kids bodies from each other — but Cyndi was ridiculous! I didnt doubt for a second that she was something of an exhibitionist — it was plain from the way she reacted that she enjoyed showing off her body to her big brother. Cyndis favorite sleeping attire was panties and a tank top — sometimes an oversized dress shirt — and she always made it a point to come out and say goodnight to me, with her arms at her sides so I could admire her tits and legs. And of course she always gave me a goodnight kiss.

Cyndi and I were very close — we always had been. I didnt mind if she wanted to prance around the house with no clothes on. I was more than willing to help her satisfy her exhibitionist urges by watching her. But I wasnt about to come on to my own sister!

Of course, Cyndi and I were very physical. She hugged everyone a lot, but especially me. And she always told me everything — well, almost everything. When shed finally lost her virginity, she had called me up at college and talked to me about it, describing the whole thing in intimate detail. Complete with a description of her giving head. It made me so hot that I jerked off immediately after hanging up. Cyndi must have known what kind of an effect she had on me. When she kissed me with those pert lips of hers — a chaste sisterly kiss, to be sure, I felt a surge of hormones go through my body and before long my cock would be standing on edge. We always trade gossip and stories — and hers were invariably sexual. Cyndi never ceased to astonish me with her horniness, or with what a slut she could be!

But then again, she always did outrageous things. And I got the biggest surprise of my life the day that Rod left to visit his own sister for a weekend. Mom and Dad would be gone for another week, so Rod had taken off from his busy schedule of boning Cyndi to go out of town.

Cyndi was spending the day out by the pool, stretched out in one of her incredibly tiny bikinis. The thing was so revealing that Cyndi might as well have been nude, though if she was, I might not have been able to control myself! She lay on a towel by the pool lawn with her legs slightly spread and her arms lifted so that her tits stretched nicely through the bikini. I was out on the deck, which overlooked the pool. Cyndi didnt know I was watching her, but I wasnt exactly hiding. Cyndis body was so incredible that I just couldnt keep my eyes off of her and that bikini didnt hurt! The top came low into her cleavage and was very skimpy on the sides, so that the smooth, curved sides of her breasts were plainly visible and quite admirable. The bikini bottoms were tight and french-cut, tucked high up between the cheeks of her ass. Her buttocks were the most gorgeous I had ever seen. Cyndis ass was nicer than that of any girls Id ever fucked, even at college. Megan had a nice ass, to be sure, and it looked incredibly sexy curved around my cock when we fucked doggy style like Rod and Cyndi, but there was something special about my sisters ass, something incredibly enticing. Maybe she just liked to show off, even more than Megan, which was difficult. Megan wasnt quite the exhibitionist Cyndi was, but Id seen both girls naked more than enough to know that neither one was very shy when it came to their bodies — especially their asses!

One of the things that turned me on most about Cyndis ass was that Id never fucked Megan that way. I had been going out with Megan for six months now, and she was just not in to anal sex. I wanted her to try it — the girls Id fucked like that had all loved it, but Meg kept refusing. Now Cyndi… she was a lot kinkier than that.

Cyndi came in periodically to get a glass of lemonade or something. Every time she got up, I moved into the living room, where Dads expensive stereo was playing, and lay down on the couch with a magazine. I didnt want to make it too obvious that I was watching Cyndi. After all, I had some morals to uphold here. When Cyndi got up, I slid into the living room and quickly put The Who on the record player. I reclined on the plush couch and picked up one of Cyndis Cosmopolitans. I breezed through it until I found a perfume ad with a sexy woman in her underwear. No wonder Cyndi was always so horny!

Cyndi came into the room, smiling and holding a glass of lemonade. Whats up, brother? she asked flirtatiously.

Not much, I smiled back, making sure my gaze didnt linger too long on her body. Now that she was up close, she looked even better. The outline of each nipple was plainly visible through the bikini. Trying to hide from the summer heat, I added.

Why would you want to do that? she asked. Its gorgeous out there!

Uh-huh, I agreed, glancing at her.

Would you like something to drink, Ian?

Hm… whats the sudden burst of charity?

Cyndi rolled her eyes. God! Im just being friendly!

All right, I laughed. Id love something. How about an iced tea?

With lemon?

Sure.

Cyndi walked out of the room, and I got a delightful view of her ass as she did. When she came back in, she was smiling again. She set down the tea and sat on the side of the couch, right next to me. So that her gorgeous, smooth midriff was right next to my face. I inhaled her perfume deeply — the perfume she wore always turned me on. I could even smell it over the magazine.

Cyndi stretched a little, rubbing her side. It drove me crazy when she did that. Im getting so horny, she giggled, I cant believe Rods going to be gone for another three days!

I chuckled. Youre getting horny, are you? Well Megan wont be here until Tuesday!

Cyndi pouted. Its not the same. Youre a man. You can satisfy your own desires.

Oh, right.

Cyndi giggled. Just teasing, she sighed. I hope I didnt embarrass you?

I began to turn red, but only a little. Nah.

Hows it going between you and Megan?

Fit as a fiddle. Shes the sexiest girl I know… well, almost.

Almost? grinned Cyndi. Whos sexier?

I wont tell, I said.

Come on, giggled my sister. Come on, Ian. You cant lie to your blood relatives. Ill tickle you. I know where youre ticklish.

Thats not fair, I said. I wont tell. Tickle away.

Cyndi leaned over and began to poke at my stomach. I burst into a wave of giggles, then reached out and grabbed for her. I accidentally touched her left tit and felt my cock give a surge. No more of that!

Be nice, I said as she collapsed, leaning against me heavily and laughing.

All right, she pouted. Dont tell me. I wont tell Megan…

You bet you wont!

Cyndi put her arms around my neck and gave me a hug. Then she kissed me, a friendly peck on the lips.

Im so glad youre my brother, she sighed. I really love you.

She giggled a little, then kissed me again. This time, her lips lingered on mine, and I felt them parting a little. Then I felt her tongue dancing against my lip, and she almost frenched me. Almost. She remained sisterly — at least on the outside. I noticed that her nipples were jutting quite erect through the damp swimsuit.

Im going crazy, she sighed, as she pulled back. I get really lonely without Rod to keep me warm at night. Im glad I have you here to keep me company — want to go dancing tonight?

Sure, I said. Ill get some champagne this afternoon.

That sounds like so much fun, she sighed. I love spending time with you, brother!

Great, Sis, I said hoarsely. Cyndi got up from the couch.

But I dont know if Ill be able to control myself if we go out. There are so many cute guys out there. And Im really getting horny. It must be tough without Megan!

Oh, its real tough, I said. Cyndi giggled and playfully reached for my crotch.

Her palm landed square on my erect cock and she discovered how hard I was. Why, Ian! she giggled, without moving her hand. You really are horny. Tsk, tsk. I should trust my brother.

Cyndi squeezed my cock playfully, and a wave of pleasure ran through my body. I almost got up and pulled her back onto the couch to fuck her right there, but she was my sister! My face turned beet-red and I looked down.

Oh, Im sorry, she said, pouting again. Cyndi sat on the side of the couch and put her arms around me. She hugged me again and touched my lips with hers. Im just teasing you, Ian. I can be such a bitch sometimes!

Cyndi slipped off of the couch and swayed toward the door, her ass luscious in those bikini-bottoms. I found myself panting heavily with relief as she left.

I almost pulled off my dong and jerked off right there. But I figured I should save myself for Megan. My girlfriend would be plenty horny when she got here on Tuesday.

When I was sure Cyndi was downstairs again, I moved out to the balcony with an issue of Playboy, rather than her Cosmo. I stretched out on the chaise lounge, watching my sister.

I reclined on the balcony, looking down at Cyndi as she basked in the sun. She usually sunbathed nude, though she always made a show of wearing a swimsuit out to the pool so I could admire her in it. Now, as I watched, Cyndi began to strip.

She sat up slowly, her face calm beneath her sunglasses, and began to untie the front of her bikini top. I watched, licking my lips, as Cyndi unfastened it and pulled the sweaty material away from her breasts. I held my breath, feeling my cock get hard in my tight shorts. Cyndi slipped out of her top and set it on the lawn next to her, then stretched in the sunlight so I could see her firm, coffee-colored tits. Cyndi had a nice tan — she worked on it enough! Her nipples were still bright pink, especially when they were hard, so they contrasted nicely to her dark skin.

Cyndi sat up and began playing with her breasts, feeling them lightly with her fingertips. My cock gave a surge of energy as I watched her doing that — suddenly she pinched both nipples at once and then bit her lip. I gasped in desire — I couldnt believe what was happening. My little sister was touching herself right in front of me!

I wondered if she knew I was watching. It wouldnt stop her if she did, though shed be hornier if she knew.

Cyndi smoothed back her sun-blonde hair and lay back down on the towel. She tucked her hands under he ass and lifted it off the ground, pulling down her bikini bottoms.

I watched enraptured as Cyndi slipped her bikini down her shapely legs and over her feet. She set the bikini bottoms — which must have been damp from sweat and (maybe) other things — next to her top. Then she stretched out nude on the towel, her hands returning to her breasts.

Cyndi began to stroke her tits sensuously, caressing her hard nipples with her thumbs and making sure to give the rest of each breast ample attention. I had watched Cyndi play with herself many times, when she left her door open a crack, or when I managed to push it open, or when Id spied through the hole in the wall Id drilled between our two rooms. But it never had quite the effect that it had now! Now that Cyndi had come closer than ever before to coming on to me, I found she turned me on still more. I watched, my hand dropping to my cock, as Cyndi covered her breasts in tiny finger-strokes. As I eyed her, Cyndis hands slowly moved downward. She pinched her nipple with her thumb and forefinger. The other hand traveled slowly down past her breasts, across her smooth belly. Cyndi spread her fingers as she parted her legs slightly, lifting her ass and exposing her tawny pubic hair.

I breathed heavily as Cyndi spread her legs. I could just see the pink slit of her cunt. She bit her lip as she played with her tits and let her free hand drop closer to her pussy.

Then, as she slid her hand over it, her cunt disappeared from view. She covered her pussy with her palm, and her middle finger slowly extended its way. I felt my cock jerking as Cyndis spine slowly arched. Her finger disappeared into her tight young slit. Gradually, Cyndi began to ease it in and out.

I watched my little sister finger-fucking herself slowly, savoring each movement she made. Her spine arched and then fell, so that her ass lifted rhythmically off of the grass. She worked her finger faster as she got wetter — her finger moved quite easily in and out of her wet cunt. She must have been well lubricated… I wondered if I had anything to do with it. Cyndis hand moved in small circles over her breasts, playing with the nipples and occasionally pinching them as her finger slipped in and out of her cunt. Then, as she got more worked up, she extended a second finger and put that into her cunt too. It was harder for her to get both in. I could tell my little sister was very tight. She started finger-fucking herself with both fingers, picking up speed as she got hornier.

As I watched my sisters gorgeous body jerking up and down with ecstasy, I unzipped my tight cutoffs and reached for my cock. I slowly peeled down the damp material of my underpants and exposed my prick. I curved my fingers around it and slowly began to work it up and down, concentrating on the motions of Cyndis hands in and out of her pussy and imagining my young sister giving me a hand-job.

Cyndi must give great hand jobs, I thought. She had plenty of practice before she lost her virginity. Why didnt I have her give me one while she was at it?

I grunted in pleasure, watching as Cyndi slowly rolled over. She got to her knees, bent over halfway. She was almost in the doggy-style position — hers and Rods favorite, as well as mine and Megans. I could see the pink slit of Cyndis cunt, it was plainly exposed between her white thighs. Cyndis fingers darted in and out of it as she leaned down, her ass still lifted but her tits and shoulders against the towel so that she could work with both hands. She turned a little, exposing one breast, and began to play with it with her free fingers. Her other hand stayed working on her cunt, getting her ever closer to her orgasm. And Cyndi didnt take long. Within minutes I knew she was going to cum from the way she was moving her body. Id watched Cyndi get fucked often enough that I could tell when she was going to come. And that was now.

I dropped my cock out of my hands. It wouldnt do to shoot my load before my sister came. I was on the very brink myself, my cock throbbing with a thick load of come. Ready to shoot into my sisters cunt. Too bad she was all the way at the pool!

Cyndis head moved around in big circles, sending her luscious blonde hair dancing around. I saw her back arching and her ass jerking back and forth — she was going to come. Then I watched her body jerking and squirming and swaying in orgasm as my little sister had her incredible climax. It must have been incredible in that gorgeous body.

I just lay there watching Cyndi as she sprawled out on the towel, stroking herself with her cunt-covered fingers. She rubbed her tits with the hand shed used on her cunt. I knew her nipples would now taste like her pussy, which I guessed was delicious. Slowly, Cyndi got up and climbed back into her swimsuit. Then she walked toward the house, bouncing with new energy in her stride.

I quickly got up and tucked away the magazine. I put Ravels Bolero on the stereo and reclined on the plush couch, panting and throbbing. My cock was so hard as I tucked it away I thought Id go crazy, but Cyndi was about to come in the house. I breathed slowly, trying not to think of Cyndis gorgeous body. Cyndi came in the room, her swimsuit askew and sweaty.

Hows it goin, bro? she asked in her most friendly manner as she came over and sat next to me again.

Great, I said nervously.

Its so gorgeous out there, she sighed. But its so hot!

Cyndi reached up and stroked her cleavage with her hand. She pulled her fingers away dripping with sweat — she was indeed hot. Shed sweated up a storm masturbating out there, her tanned skin looked very sexy all slick with sweat. And I could smell her pungent sex — it made my cock stay quite hard as I talked to her.

Yeah, I said. It is getting hot.

And Im so horny! I just cant stand to lay there without anyone! Its driving me crazy! she giggled. What do you do when you cant take your mind off sex?

Um… why, what do you want to do?

Cyndi put her arms around my shoulders and hugged me. She held herself there, her tits pressing against my chest. She let her hand drift across my chest through my tight tank top. Cyndi stared into my eyes and sighed.

What I want to do would be… bad. She looked down sadly and then giggled a little. Wouldnt it?

Why, I grinned. What do you want to do?

Cyndi playfully reached down and tweaked my cock again. This time I grunted in pleasure. She looked surprised but then laughed.

Cyndi got up, stroking my chest one more time briefly as she did. She looked down at me and smiled.

I want to take a cold shower, she said softly. She walked toward the door and paused.

Her ass looked curvaceous and beautiful the way she was standing. She smiled. Or maybe a hot one!

I gulped uncomfortably. I sat up on the couch.

What do you think, Ian?

Take a hot one, I said softly.

Cyndi smiled vaguely, then gave me her sexiest coy stare. She licked her lips suggestively. All right, she said. Ill take a hot one.

She turned slowly and said, Ill leave the bathroom door open.

CHAPTER TWO

Id watched Cyndi take plenty of showers, but for some reason this one turned me on even more. I knew quite well that the bathroom we shared was easy to peek into. There was a very wide gap between the sliding door and the jamb, and that made it easy for me to spy on Cyndi as she rubbed herself down and got all soapy in the shower. The shower was just that — the bathtub of the house was in Mom and Dads bathroom. The shower stall didnt have smoked glass like most of them but only vaguely misty stuff. It hid a fair amount, but I could always make out what Cyndi was doing to herself. And Cyndis nude form looked that much better when it looked foggy and mysterious.

This time, though, the doors were wide open. Both of them. I walked into the room as I heard the water go on. Cyndi was already in the shower. I felt my cock giving a little burst of lust as I thought that she was now naked. I walked slowly toward the bathroom. Could I do it? Could I take my little sister up on her lustful desires?

Id always played protective brother with Cyndi, but I didnt doubt that she could take care of herself when it came to sex. As a matter, shed shown me quite handily that she could already take care of herself in bed. Cyndi was an expert. There was no reason for me to back off if she was begging me to fuck her and of course thats what she was doing! I was just like another guy, with lust for Cyndi that would fill a canyon. My cock began to throb with anticipation as I neared the bathroom.

I stood at the door and looked in. Cyndis nude body was visible through the glass door to the shower. She was staring up into the water-stream, and her gorgeous golden hair hung down over her shoulders. The pleasant slope of her ass was lifted high and enticing. She took a step back, rubbing the hot water over her tits.

The bathroom was filled with steam, just like Cyndi. I smiled as I moved closer.

Cyndi turned quickly and saw me. She smiled through the door and lifted a finger, curving it toward her and beckoning me into the shower with her.

That did it. I couldnt hold back. My sister was just asking me to fuck her in the shower and I knew quite well that she meant it.

I slipped out of my shirt, and then out of my shorts and underwear. I stood there stark naked and sweaty, with my hard-on jutting out of my body. If I went in there with Cyndi, shed see my cock all erect and know how much I wanted to fuck her. I started to turn red with embarrassment, but, of course, she already knew.

I opened the door to the shower, and there was Cyndi — nude and covered in hot water. She smiled at me through the curtain of her wet hair. She licked her lips and I stepped into the shower.

The hot water splashed all over me as Cyndi put her arms around my shoulders. She pulled me against her naked body and soon I was soaked like her. I felt Cyndis firm tits pressing against my chest and felt her rubbing up and down so her hard nipples scraped my flesh. Then Cyndi thrust her mouth against mine and I felt my sisters tongue throbbing into my mouth.

Mmmmm… sighed Cyndi. Ive been meaning to do this for a long time now. Cyndis hand slid down to my erect pole and curved around it. I grunted as Cyndi took hold of my cock, slowly bringing it around in big circles.

Cyndi ran her thumb sensuously over the head of my prick as she milked a drop or two of pre-cum out of it. Shed been turning me on all day and I was ready to cream for her. But Cyndi would no doubt tease me further before letting me cum. I didnt know if she wanted to go all the way, maybe that kind of incest would have been too much for her. But I was aching to put my cock in her mouth and cunt, and creaming now would be cheating me of my rightful fuck. I held back as Cyndi stroked me. Her tongue quickened, seething in and out of my mouth. She nibbled at my lower lip and closed her lips around my tongue, tugging at it suggestively.

She leaned against me, putting her head on my shoulder. Her luscious wet hair dangled over my chest. I put my arms around her, too, and cupped my fingers around her smooth ass-cheeks. I couldnt believe I was finally pressed against my sister, naked and wet. And she was really going to take me to bed.

Ive wanted you for a long time, Ian, she sighed, kissing my shoulder. I just couldnt tell you about it. Rods just a diversion to keep me from thinking about how much I want to fuck you. Your cock feels so good… will you go to bed with me, Ian?

Ill do anything you want me to, Cyn. My voice was hoarse and husky. I called her Cyn when we were being chummy, which I felt sure was being right now. As a matter of fact, we were being more than chummy. It was like Sin, which Cyn was indeed close to. As a matter of fact, we were committing one right now, and nothing had ever made my cock harder.

I want it to be in Mom and Dads bed, said Cyndi. I want you to fuck me there. Please?

Ill fuck you anyplace youll let me, Cyndi. Im dying to put my cock inside you.

Good, sighed Cyndi. Dry off and go up there. Ill be right in.

I nodded and Cyndi kissed me one more time. Her tongue trailed along my lips. I got out of the shower and watched her gorgeous body as she rinsed herself off. I dried myself and walked naked up the hall into Mom and Dads room. They lived in the biggest room of the house. It was enormous and sumptuous, with velvety walls and a canopied bed. Part of the ceiling was mirrored. The window-seat overlooked the garden and the pool — it was the next best place for spying on Cyndi. Id seen Rod and Cyndi fuck standing up on the balcony, with Cyndi bent over the railing and her ass lifted high on her spread legs so Rod could enter her from behind. The master bath had an enormous Jacuzzi instead of a bathtub — well, it was technically a bathtub, but the Jacuzzi outside was less suited to fucking. This one was made for it. And the shower had plenty of room for two. Mom and Dad were parents for excess. Cyndi had learned a lot from them.

I climbed into bed. Cyndi had put the satin sheets on — they felt sexy. I knew theyd be great to fuck on. Id seen her change the sheets just this morning. I wondered if shed been planning to fuck me. Probably so — she was one horny chick.

I panted heavily as I lay there waiting for my sister to come in and go to bed with me. I couldnt believe I was doing this. I was really going to bone Cyndi! And not just bone her — I was going to fuck Cyndi for all I was worth. I was wild with lust and nervousness, but I felt sure Cyndi would show me the way.

Cyndi came into the room wrapped in a towel and nothing else. Her hair was a little wet — shed toweled it off in the bathroom. But the skimpy towel wrapped around her middle didnt do much to hide her wet body — the towel came just above the bottom fringes of her pubic hair, showing me Cyndis wispy curls. And the top just showed Cyndis nipples poking through. Her eyes were big and moist and her lips were parted in horny anticipation. Cyndi let the towel drop to the floor and stood there stark naked, letting me watch her.

As she moved toward the bed, Cyndis hands drifted across her breasts. I caught my breath as she pinched the nipples gently. To see her do that across the yard was one thing — but to watch her do it as foreplay to fucking me — that was too much. My cock twitched in desire.

Ive… been… wanting… to fuck you, Ian, panted Cyndi rhythmically as she knelt on the side of the bed. Even though youre my brother. Youve been my best friend… and theres only one thing we havent done together. Now I want to do it… and keep on doing it. I want to feel your cock in my pussy.

I kept thinking how sexy Cyndi looked with her body all wet like that. Little drops of moisture kept running down her inner thighs, and I wondered how much of it was water. I guessed a fair amount was something else, and that made my cock seem to get bigger.

Cyndi climbed onto the bed, her legs slightly spread and her wet pubic hair hanging down between them. Drops formed and ran down onto the satin sheets. I pulled the sheets open and exposed my naked body. A visible shudder ran over Cyndis nude form. She began to breathe more heavily. Cyndi bent slowly down and lay on top of me.

Her bare body pressed against mine and sent an electric thrill through me. She eased one leg over me and straddled my hips. She lowered herself on top of me, and I felt her wet thatch of pubic hair rubbing against my cock. Cyndi pressed her lips to mine and settled firmly on top of me. Her breasts were firm and enticing against my hairy chest, and her hard nipples pressed against mine. I parted my lips and thrust my tongue out, french-kissing Cyndi as she rubbed her tits against me.

This feels so good… panted Cyndi. Ive wanted to hold you naked for so long… promise me youll sleep with me tonight, Ian. Will you?

I promise, I grunted, dropping my hands to touch her ass. I cupped her ass in my hands and massaged it gently. All I could think about was how sexy it had looked when Rod had shoved his cock into her asshole. But Cyndis cunt was much more enticing right now and Cyndi was rubbing it against my cock.

Oh… yes… I want you inside of me, breathed Cyndi slowly. She rubbed her swollen, wet cunt-lips up and down on the long shaft of my prick. I reached around and slid my finger gently inside her. Cyndi let out a loud moan of pleasure as she felt it penetrating her. My mind reeled — I was finger-fucking my own sister!

But it felt so good! I began to slide my finger quickly in and out of Cyndis snatch, moving my thumb down to toy with her clit. As I touched it, a shudder of ecstasy ran through Cyns body.

Oh God, Ian… finger me…

I began to work my finger in and out of Cyndis cunt. As I had suspected, she was very tight. No matter how many times she had fucked, Cyndi had still only lost her virginity a few months ago. I pressed two fingers in and Cyndi let out a loud groan.

That feels so good… I want you to fuck me… but first, I want to taste you. Can I taste you, Ian? Cyndi looked into my face with her big, gorgeous blue eyes pleading. Can I give you head first, please? You dont mind, do you?

At first I thought she was kidding. But Cyndi has always been a shy child, and she desperately wanted to please me. I smiled.

Please, I panted. Please give me head.

Oh, yes, sighed Cyndi as she kissed her way down my body. She paused at my nipples, taking those in between her lips and suckling at them. Then she licked a long trail over my stomach, tugging at my hair with her teeth. I felt her cunt dribbling against my lower legs as she straddled me wider. Cyndis hot breath fluttered over my erect cock. She parted her lips and eased her tongue over my lower stomach, lapping up the thick dollop of pre-cum that had formed there. I groaned as I felt my sisters tongue straying over my cock-head and this was too much for her! She slurped at my cock-head hungrily, and then pressed it quickly between her full, young red lips. I held my breath as I felt Cyndis tongue traveling all over my upper cock-shaft. She sucked at my cock with her lips clamped tight around it. She tugged it almost straight up and then began to work the long shaft into her mouth.

It was incredibly sexy to watch my shaft sinking in between Cyndis lips. Cyndi had given head to so many guys and now she was finally giving me head, her mouth clamped over my cock. And I knew from watching her that she gave the best head imaginable. Girls with cock-hunger like Cyndis always do.

Oh yeah, baby… go for it, Sis… take it all… deep throat me…

Cyndi pressed the thick head of my cock into the softness of her tight throat. Then, straightening her head, she pressed it firmly in.

Oh God Sis — thats so good… suck me! I lifted my hips to meet Cyndis demanding mouth-thrust and with my help, Cyndi got my long cock all the way into her mouth. I heard her whimper in pleasure as it sank in. Cyndis tongue seethed against my flesh. She knew how to give good head all right. As a matter of fact, my cock was already throbbing to spurt inside her. I brought my hips up firmly into Cyndis face, then back again. I began to fuck her rhythmically, putting my cock into her mouth as she sucked at it.

Oh yeah, Sis… eat it… you give the best head, Sis… Im gonna cum in your mouth… just keep doing it like that…

Cyndis head came down rhythmically over my erect cock, shoving it into her warm wetness with the perfect timing it took to bring me closer and closer.

Cyndi curved her fingers underneath me, cupping my buttocks as she gave me head. I spread my legs wider to give her a better shot at my cock. She swallowed it again and again as I groaned. Cyndi clamped her lips tighter as she heard me moaning — she knew I was about to cum, and she didnt want to miss a drop!

Oh yeah, Sis — Cyn — Im cumming in your mouth! I couldnt believe I was saying these things to my little sister! But here I was, and I was about to cum! I felt my cock jerking as a stream of jizz shot out into Cyndis mouth — she squealed in delight as she felt the hot fluid shooting down her throat. I fucked her face rhythmically as I came, working my cock into her faster as the jizz filled her mouth. When I was finished cumming, Cyndi swallowed it all and licked my cock sensuously.

She moved up my body and rested against me. That was incredible, Ian. Thank you for letting me do that to you. I love you.

Thats good, Sis.

I want you to fuck me. In my cunt. Please?

I grunted as Cyndi wrapped her fingers around my soft cock. She stroked it with her thumb, teasing me into another erection. As she petted my cock, I felt it getting hard in her grasp.

Ive wanted you for so long, she sighed into my ear. Ever since Ive lost my virginity, all I can think of is getting your cock in my pussy. I want you to cum in my slit. And in my mouth — again. I want to keep fucking you forever. I want you to cum everywhere you can on me. Please promise me youll fuck me good… brother I need your cock.

Cyndi rubbed my cock slowly up and down. She licked my ear hungrily, tugging at it with her teeth. She breathed warmly over my neck and ran her cunt slowly over my long shaft. I could feel her wet hair dangling against my cock. And her longer hair dangling on my chest.

Ill fuck you, I said. Im going to fuck you, Cyndi.

Oh please, she panted, rolling slowly off of me. She got onto her back, staring up at me as I lifted myself on my elbow.

Cyndi spread her legs slowly, her hands lying limp at her sides. Her lips were parted and slick with my cum. She was ready for me to fuck her. But I was her big brother, so I should be on top.

I had other ideas. Id watched her take it this way so many times that I wanted to do it myself the first time. I grinned at her.

Roll over, Cyndi. Im going to fuck you doggy-style.

Cyndi looked surprised at first, but I could see a wave of lust roll over her body. She nodded, her breathing shallow and quick. I watched as she rolled onto her stomach and then got to her knees, spreading her legs and lifting her ass in the air. She propped herself up on both elbows, so that her tits dangled down nicely.

I got behind Cyndi, between her parted legs. I looked down at the shapely curve of her ass. Her cheeks were spread slightly with her thighs. Her asshole was exposed, and it looked pink and luscious. That would have to be next.

I reached in between Cyndis legs and felt her slick, swollen cunt-lips. I pressed two fingers into her, penetrating her cunt slowly. Cyndi moaned loudly as she felt them going in.

Oh God Ian… that feels so good.

Hearing her turned on like that, I didnt want to stop even to put my cock in. Instead, I worked the two fingers slowly into Cyndi, again and again as she pressed her ass back into my grasp. I put one hand on her buttocks, steadying her as I finger-fucked her from behind.

Oh yeah… thats good… keep doing that… oh Ian… I want you…

Cyndis ass gyrated in time with my finger-fucking. She took my fingers doggy-style, picking up speed as she got more and more turned on. And watching Cyndi twist on my fingers was sexier than watching her twist on someone elses! I thrust my fingers in and out of Cyndis tight cunt, amazed at how tightly her snatch gripped me. Cyndi turned her head, panting heavily. Her face was bright red with exertion and desire. I could see that her tits were flushed, too. And it wasnt from the shower. She began to whimper.

Put your… cock… in me, Ian! I want you to fuck me. I nodded, sliding my two fingers out of Cyndi. I climbed between her parted knees and lifted her hips ever so slightly to guide her pussy down to my cock-head. Cyndi groaned loudly as she felt her cunt nearing my shaft. She willingly let me ease her body down. She pressed her ass against me, though, as she felt my cock beginning to penetrate her. I pressed my cock up to Cyndis hole, barely entering her. Her cunt felt good against my cock, and I could feel the head seething as I entered her. I worked the head into Cyndis tight flesh and she let out a scream of ecstasy.

OH GOD IAN! she screamed. I cant believe it. Its so good, brother, I love it. She turned her head and stared right into my face with those big blue eyes. Put it all in. Put your whole cock inside me. Promise me youll put your whole shaft in there.

I nodded. I will, Sis. I will, baby.

Cyndi groaned as I eased my cock into her. She felt the long shaft stretching her cunt, opening it up for the whole length. I held her hips tight, my thumbs pressing into her buttocks. I made sure Cyndi was steady as I entered her.

Cyndi let out a shriek as she felt my cock settling all the way into her. I know from all the women Ive fucked that my cock is bigger than most guys — and my sister Cyndis cunt is tighter than most womens. Thats why it felt so good to have my cock shoved all the way up Cyndis tight cunt-hole. Her pussy lips gripped my long cock shaft with as much force as I could want. It seemed like her heartbeat massaged my cock as I slid it into her. Grunting with pleasure and exertion, I began to drag my cock back out of her — just far enough to shove it in again!

OH, oh YEAH! moaned Cyndi as I rammed my cock into her tight cunt once more. Cyndi whimpered in ecstasy as I began boning her quickly, working my cock in and out of her cunt. She writhed and quivered with pleasure. Her whole body was flushed from the exertion of giving me head and taking my cock up her cunt as well as the desire to have me fuck her. Cyndi was amazing — she seemed to shudder with each thrust I gave her. She moaned and writhed and bit her lip as I shoved my cock into her. She was really turned on and hot for my shaft. Cyndi began to whimper every time my cock-head sank to its deepest point in her warm wetness. She groaned as I penetrated her again and again. I fucked her doggy-style, holding on to her hips and her ass-cheeks as I boned my cock into her. Her cunt felt so good around my cock that I couldnt believe Id waited this long to fuck my luscious sister. I watched Cyndis gorgeous ass bobbing up and down with the rhythm of my cock going into her. Her asshole looked tight and delicious. I knew before long Cyndi would ask me to enter that way and Id gladly oblige, finally finding out what Cyndis asshole felt like from the inside. I groaned as I shoved my cock into Cyndi. She was going crazy, panting and shuddering with pleasure as I entered her. Cyndi looked back at me, her eyes wide and her lips parted, begging me to fuck her harder. I summoned up all my energy and started pounding my cock faster and faster into Cyndis snatch, but I knew that before long I was going to cum!

The thought struck me that I was boning my own sister doggy-style. I couldnt believe how kinky this was. And I was about to cum in her snatch. I was very glad Cyndi was on the pill. Id hate to explain this one to Mom. Of course, maybe Mom understand — after all, we were doing it in her bed…

Oh God, Ian… Ian… oh God, that feels good! Cyndi began working her snatch up and down in time with my cock, meeting every thrust of my hips with one of her own. Thats so good… fuck me… hard… deep… Its so good… Keep doing it… Im going — OOOOAAHHHHH…

Cyndi groaned as she got ready to cum. I watched her face twisting in ecstasy. Cyndi was the most beautiful girl I knew, and here she was cumming while impaled on my long shaft. As a matter of fact, she was going to make me cum at about the same time she did. I was getting very close!

Uh… I groaned. Cyndi… Sis… Im gonna cum in your pussy.

Do it, she whimpered. Spurt into me. I want to feel it. Please, Ian. I need your cock.

Oh God, I panted. Youre so good… your cunt…

Yes, baby, cum in my pussy. I want your cum. Spurt for me!

I rammed by cock faster and faster into Cyndis pussy. Cyndi shoved her ass quickly up and down on my cock, impaling herself again and again on my long shaft. When she realized that I really was going to cum in her, she let out a moan and then began to quiver in delight. As I felt my cock throbbing and swelling with near-orgasm, Cyndis cunt contracted in rhythmic spasms of pleasure.

Oh, God, Ian… youre making me cum! Im cumming… youre making your baby sister cum. Make me cum. Fuck your baby sister, she panted. I felt her shuddering in ecstasy, orgasm flooding her body quickly as she lifted her ass and thrust it down hard so that her cunt swallowed up my cock every time. I watched Cyndi going wild with her climax — she was mad for my cock!

Cyndi slumped forward on the bed, letting her big brother fuck her rapidly and increase the intensity of her orgasm.

Im cumming… cumming… cumming… uh… uh… uh… she panted rhythmically as she quivered in pleasure. Then, with hard thrusts into my little sisters tight snatch, I began to cum.

Oh God, I panted. Im cumming inside your… your… pussy… its good… good… yeah… fuck me.

Cyndis cunt felt so incredible around my cock. My prick jerked up and down in orgasm and I felt it spewing out a thick stream of jizz into my sisters wet slit. She was whimpering and begging for more in pleasure as she felt me put it into her again and again. Cyndi was crazy with desire. Her whole body was quivering as I boned her. My cock seethed into Cyndis snatch rapidly as I spurted into her.

I could feel my cum dribbling out around my sisters thick, lust-swollen pussy-lips. As the cum formed in droplets and ran down onto our parents bed, Cyndi pressed her tits against the sheets and stretched her arms out, prostrating herself so that she lay there passive and just took the thick streams of cum from my prick-head. When I was finished cumming, I slumped forward on my sisters nude body and pressed my lips against her sweaty neck.

Oh God, Sis. Your cunt is so good. I cant believe what a good fuck you are.

Cyndi eased herself out from under me, tugging her cunt away from my cock so that I left her quickly. She put her arms around my shoulders, lying on her side and facing me.

Youre going to fuck me a lot, she sighed. Now that Ive got your cock inside me, I dont ever want it out of there. I want you to fuck me all the time.

Ill fuck you as much as I can, baby.

Cyndi leaned heavily against me, her face against my chest. Ive been dreaming of this for a long time brother. Now we can take a nap together… in this bed. We were conceived in this bed. We were conceived in this bed, honey isnt that sexy?

I chuckled. You bet, I said. Mom and Dad fucked in this bed… and Dad came in Moms slit…

Moms slit, sighed Cyndi longingly. Its so fucking sexy. And we just fucked in it. You just fucked me doggy-style in this bed. We just committed incest in this bed. Oh God.

I nuzzled Cyndis ear. Thats great. Were going to fuck a lot more in this bed before Mom and Dad get back.

And maybe after, sighed Cyndi. I want you to… do things to me.

What kind of things? I asked her, whispering into her ear as I licked it.

What would you think… she began to ask me, but got nervous and buried her face in my chest.

What baby? I love you, Cyn. Ill do anything for you.

No, she said. Its too dirty.

What? I stroked her back soothingly. Tell me. Ask me. Ill do it, baby.

What would you think if I asked you… she paused, panting heavily into my ear. Would you… would you put your cock in my asshole? Would you fuck me up the ass?

OH God, baby, I panted, Id love to. Ive been dreaming of fucking you that way…

Tonight? she begged. I want to think about it all day… I want to know that youre going to fuck me up the ass. Promise me youll fuck me up the ass tonight?

Ill do it, baby. Ill beg you to let me do it!

Oh, God, yes, Ian, panted Cyndi. I can hardly wait until tonight. Lets get drunk together. Were going to spend all night together, nude in each others arms. Its so sexy. Well sleep in the bed where Dad came in Moms pussy and conceived us. I can hardly stand it.

Yeah, baby. Ill get some champagne — Well drink it and get drunk and then Ill fuck you up the ass.

Oh, brother. I love you so much… Im so glad were finally in bed together…

Me too, Cyn, me too.

***

I was indeed glad that my delectable sister Cyndi had seduced me. After all, Id been dreaming about that moment for months now. The moment when I penetrated Cyndi, stretching her tight young cunt-hole with my cock and sliding my entire long shaft into her so she moaned in pleasure. And now I knew quite well that I would be doing it to Cyndi for some time to come. And to cum, certainly! Cyndi was the sexiest slut I had ever known and she was my own sister. Not only that, but she seemed to be in love with me. And I loved my sister very much. I would give her everything she wanted. What I wanted more than anything was to bone Cyndi till my cock was slick with her cunt-juices. Todays fucking had been more than my wildest dreams would have hoped for.

Cyndi held me in her arms and she dropped slowly off to sleep. I felt myself drifting too, and before long I was relaxed and groggy in my sisters arms. Cyndi and I slept together in the bed where wed been conceived, our nude and sweaty bodies pressed together. Cyndis heartbeat throbbed rhythmically against my chest, matching the rhythm, it seemed, in which wed just fucked.

CHAPTER THREE

Cyndi and I lounged in the huge bathtub. Cyndi was turned on her side and lying half on top of me so that her firm tits rested on my shoulder. Her face was nuzzled against my neck. She kissed me every few minutes, touching my skin with her wet lips and sensuous tongue. Her hand lay in my lap, curved absentmindedly around my cock, which was quite hard despite the fact that Id already cum twice. Cyndi was quite the tease, though — she just barely touched my cock, letting her thumb trail gently around the head under the hot water. The bubbly suds hid what she was doing, but since most of her luscious form was out of the water and on top of me, I could see many of the curves of her naked body. Cyndi sighed, kissing my ear.

Im so happy I finally went to bed with you, she whispered. Ive been wanting to feel your cock inside me for so long. I dont know why I didnt come on to you sooner.

Ive been watching you, too, I said. Sis, youre one of the easiest girls to spy on Ive ever seen.

Cyndi gasped in mock surprise. Youve been spying on me?

All the time. Its an obsession.

What — what did you see? She smiled as she looked into my eyes.

I saw you doing some very kinky things with Rod. And those three other guys. And more than that I saw you changing your clothes and sunbathing a lot. Youve got an incredible body — I couldnt look away!

Oh, I feel so violated! Cyndi giggled. Did you like what you saw?

I wouldnt have put my cock inside you if I didnt, right, Sis?

Oh, I dont know…

I put my lips on hers and tickled her mouth with my tongue. Sis, I love your body. And Im tired of spying on you. From now on, I intend to see it from up close.

Cyndi sighed and put her arms around me, rubbing her soapy tits against my chest. Thats good, she said. Im going to be very close to you, with my legs spread. Anytime you want to spy on me, you just tell me, brother. And Ill do it for you — up close.

Id like to see you giving a hand job in the bath, I grinned.

To my very own brother? You mean, committing incest?

Aw, its not incest if I dont cum inside you, Sis. Isnt that right? The incest taboo is just to keep the genetic lines pure. And youre on the pill, so it cant be incest, right?

Cyndi giggled. You think about this a lot at school, eh brother?

Anthro majors learn all about sex.

Cyndi sighed and kissed my cheek. Its incest, she sighed. Thats what turns me on so much. Im in love with my brother, and I cant stop wanting to fuck him. Put his cock in between my legs. Cyndi panted rhythmically as she spoke.

She slid her hand down on my cock, slowly caressing it with her soapy fingers. Her breathing quickened as she ran her thumb over the head and tightened her fingers around the shaft. I grunted in approval as my sister began to jerk up and down on my cock. She pressed her lips against mine and started french-kissing me deeply, nibbling at my lips and tongue and suckling at my mouth. She let out a whimper as I dropped my hand to her ass and kneaded her smooth buttocks, spreading them slightly. But Cyndi didnt slow down or ease up pressure on my throbbing, hard cock. She kept jerking me off.

I breathed slow and heavy into Cyndis ear as she manipulated my cock up and down. She started bringing it around in smooth, slow circles, sending shivers through my naked, soapy wet body. Cyndi squirmed on top of me, pressing her own nude form down against me. Her breasts slid rhythmically against my flesh, we were both so covered in soap that we were incredibly slippery. Even so, Cyndi managed to keep a good grasp on my cock, jerking me off in circles. She knew just how I liked it — thats what I did when I jerked off myself, like when I was watching Cyndi, which was often, believe me! I wondered if shed watched me herself — after all, the door to the bathroom was frequently open or ajar, and I lay on my bed with my legs spread and my cock in my hands. Or maybe Cyndi was just so attuned to her big brothers cock that she knew what I wanted instinctively.

Cyndis hand moved in bigger and bigger circles, grinding against my cock. She moved my prick like it were the crank on a generator building up a current of desire. I squeezed my sisters ass-cheeks tighter, bringing her up and down as she played with my prick. She whimpered as her gorgeous body bounced up and down on top of me. I grunted in time with her cock-jerking as Cyndi lifted her head and stared into my face.

I want you inside me, she panted. I want you to cum inside me again.

I nodded, out of breath from the intensity of fighting off my orgasm. I didnt want to cum yet. I wanted this sordid, incestuous tryst to last as long as possible before I shot my load into Cyndis hand. But now Cyn was begging me to fuck her again — and I certainly couldnt say no to my sister!

Yeah, baby, I panted. Ill fuck you. Spread your legs wider.

Cyndis soapy thighs were clamped around mine under the water. She slid against me, spreading her legs wider so that she floated up.

Like this? she asked nervously, putting her knees on the floor of the tub. That way her cunt was under the soapy water, but just above my erect rod.

Thats right, sister, I panted, taking hold of her ass more firmly. I pulled Cyndi down onto me, pressing my cock up so that the bulbous, inflamed head met Cyndis tight hole. She was wet, all right, and not just from the bath oil! I lifted my hips and heard Cyndi gasp in pleasure as my cock worked its way up and down in between her cunt-lips.

I didnt enter her yet, though. I wanted to tease my sister into a fucking frenzy. I rocked my hips back and forth, sliding the arrow-shaped head of my erect pole slowly up the whole length of Cyndis slit — pressing into her soft flesh, but not going into her tight hole. Cyndi stared down at me, her breasts flecked with soap and gorgeous. Her eyes went wide as my cock head pressed against her clit. Then I slowly slid it down again, away from Cyndis clit and nearer to her cunt-hole. Her eyes stayed wide, though, wide and pleading. She was begging me to fuck her. Her eyes just demanded that I put my cock inside her. But I wanted to see my sister moan in desire before I penetrated her.

Put it inside me, panted Cyndi. I chuckled as I teased her. I worked my cock head up against her cunt so that the very tip was inside her hole. Her eyes fluttered in ecstasy and I heard her breathing change with each throb of my shaft. Then I tugged it out again and slid my entire length against her slit, in between her swollen, slick pussy lips. Cyndi moaned and squirmed down harder against me. She spread her legs as wide as they could go, kneeling astride me on the floor of the tub. Cyndis lips were open wide, and I watched them quiver as I neared her cunt again with the head of my cock. Her tits bounced up and down with every shudder of frustration and desire that went through her nude body. But Cyndi wasnt going to take the initiative — she wanted her brother to enter her when I decided it was right.

That feels so good, Ian, panted Cyndi. I want your cock… in my pussy.

I couldnt stand it anymore! Cyndis cunt was so delectable and warm, and Id only fucked it once. I simply had to have it again — and right now! Cyndis nude body was incredibly gorgeous, shaking, all flushed and hot over me. I wanted to impale her with my cock. I took firm hold of her buttocks and pulled her down hard, putting my cock against her cunt.

Oh yes, Ian, she moaned wildly, almost a sob of bliss. Enter me. Fuck my cunt. I want you to cum in my slit… oh!

I drew my hips around in tiny circles, teasing Cyndi the same way shed teased me. I began to work my cock in, every circle pushing it just a bit further. Cyndis moans and begging pants grew louder. Then, unable to stand it anymore, I pulled Cyndi down on top of me so that her tits pressed against my chest. With a long thrust of my hips, I entered her.

OOOOOHHHHH-Uh… uh… good… oh Ian, she whimpered and moaned and gnashed her teeth, biting at my neck and ear as I penetrated her. Cyndi squirmed against me as I shoved my cock between her spread legs, sliding it all the way into her cunt. She was tight. My cock felt like it was in a vise-grip of pleasure! I grunted and held my shaft in there, savoring the feel of Cyndis hot cunt around me.

Oh God, Ian, she panted as I began to fuck her.

I slid my cock slowly in and out of Cyndis cunt, working her up as I picked up speed. My cock was swollen and bursting with cum.

I love you, Ian, panted Cyndi into my ear as I fucked her hard. I really love you… your cock is so good… keep fucking me.

Oh, yeah, baby. Im gonna cum.

Yes… oh Ian… cum in my slit… keep fucking me till you cum…

Your cunt feels so good…

Harder, brother! Fuck me harder!

I shoved faster in and out of Cyndis cunt, grunting rhythmically as I entered her again and again. She straddled me and rubbed her tits against my chest and then with a huge groan, she began fucking her hips up and down in time with my cock plunging into her. I let out a moan of pleasure — I was about to cum!

Oh, yeah, Sis, keep fucking. Im gonna cum in your snatch.

Uh — Ian, cum in me.

My cock jerked and began to spurt. I felt my muscles twitching as waves of pleasure ran through me. Thick streams of jizz burst into Cyndis cunt as I pounded into it. As I finished spurting, Cyndi went limp on top of me, whimpering.

I cant wait till tonight, whispered Cyndi, slowly rubbing her erect nipples against my soapy chest. Youre going to get me shit-faced drunk and fuck me up the ass. Youre going to ass-fuck me on our parents bed. Youre going to get me drunk… and spread my cheeks… and enter me… promise?

Sis, you couldnt stop me now. Im going to ass-fuck you whether you like it or not.

Dont say that, she giggled. Dont think for a second I want anything except your cock up my ass. She sighed, rubbing her lips against my ear. Promise me youll be rough. Throw me on the bed and fuck me up the ass. Fuck me good and hard — thats the way I like it.

Ill do anything you want, baby.

Good. Cyndi sighed and began nuzzling my throat. I say we buy expensive champagne. Im going to drink a lot of it. Whenever weve gotten drunk together, Ive wanted to kiss you. Ive wanted to unzip your pants and go down on you. Last night when you came in my mouth it was… oh, Ian, it was a dream. I loved it. I want you to cum in my mouth again soon. Promise me? I want to swallow all your cum. I love the way you taste. Remember when you got me drunk over Christmas vacation?

I remember, I said.

I kept hoping youd slip your hand under my shirt when we were sleeping on the couch. But you didnt. I was so horny for you, I could feel your cock against my ass. I didnt really sleep all night. I was too horny! I could feel that you were hard. I knew you wanted to fuck me. And now you are.

You bet I am, I sighed, stroking Cyndis back soothingly.

And a good thing, too, said Cyndi. I was about to go bonkers from lust for my brother!

CHAPTER FOUR

It was Friday night, but Cyndi and I stayed in. I got some expensive champagne at the liquor store on Mom and Dads charge card. Cyndi stayed home and got ready for a long evening of subtle drinking and talking and afterwards, some incredible balling.

She looked gorgeous. Cyndi had put on her best make-up, and she had a certain glow about her. She was very eager to spend some time with her older brother. We lay down on Mom and Dads bed, stretched out sensuously with our champagne glasses. Id even gotten out the ice bucket so we could keep the drink chilled near the bed. Cyndi wore a shimmering grey nightie — a very short one that just came past her hips so that her gorgeous legs were displayed. They were smooth and looked particularly enticing. From the first glimpse I got, I wanted to spread them and lie between them. Under her nightie, Cyndi wore a pair of lacy string panties to match. The panties were tight and skimpy, and I could see the outline of her pale pubic hair underneath. The lace was see-through, so I could catch the shape of her warm cunt past the crotch when she bent over or twisted around. The nightie was lacy, too, and the neckline was very low and showed her pert breasts. Her nipples were already hard and pink and erect, and jutted through the thin satin of the nightie. It was sleeveless, so I could see Cyndis shoulders against the spaghetti straps. Cyndis hair hung loose and wild around her neck. She wore long silver earrings that complimented the shape of her face.

I came into the bedroom and slipped out of my jeans and shirt. I lay down on the bed in just my tight jockey shorts. I gave Cyndi a kiss and before long her tongue was sliding in and out of my mouth. My cock bulged hard against my underpants as Cyndi kissed me.

When she pulled back, we picked up our champagne glasses.

To us, she said, clinking glasses with me.

And to incest, she giggled, winking at me. She sipped her champagne as I felt a rush of lust for her. But I held myself back — I wanted to savor the evening of fucking with my sister. I knew what I was going to do later, just what Cyndi had asked me to do later. I was going to lay Cyndi down and fuck her up the ass. But for now, I just ran my eyes over her skimpily clad form and watched her breasts slowly moving up and down as she breathed.

Cyndi took a few sips of the champagne, and then lifted the glass and gulped it down. She licked her lips, breathing heavily as she
