Instant Nympho

I felt like saying that I'd felt it way ever since I was 10, but I didn't. I feigned confusion. I stood up, letting go of her tits and looking down at her beautiful upturned face. 'But Wendy...I think maybe you were right the other day...I'm not sure we should be doing this sort of thing. Are you...' I stopped in mid-sentence; Wendy had pulled my sweats down to expose my huge erection. She immediately had her hands all over it.

'You do feel it, Mark. Look how big and hard your cock is...Mmmmm.' She stroked it slowly and sensually. 'Don't deny it; you want it just as much as me. Oooooh....' Then once again she popped it into her mouth and started giving me a slow, luxurious blowjob. Man, my sister could suck dick. She kept looking up at me; she wanted to watch her suck my cock. After a minute or two of sucking, she let go and stood up. Her breathing was heavy and her look intense. 'It's too late to stop now, Marky. Let's do it again. Just once more...please?' She looked down at my pecker, standing at full attention and slick with her saliva. 'Please help me. I need it so bad!' She pulled me over to my bed and slipped off her undies. 'Lay down.' I anxiously complied, trying to appear reticent, wich was tough with my hard on raging like it was. I decided to remain completely passive and watch the show. I lay flat on my back in the middle of my bed. Wendy leaned over and kissed me, sliding her tongue into my mouth and wrestling with my own. She ran her hands over almost the entire surface of my muscular body, lingering at my cock and balls. 'God, you're so beautiful...' Then she climbed onto the bed, maneuvered herself up over hy head, and said, 'Eat my pussy...I know it's wrong, Marky but I need you to lick me...lick my cunt....Ohhhhhhhhh, yeah, just like that.' She tasted and smelled delicious. She was so wet and hot and she looked down into my eyes as she directed me. 'Put you tongue inside...Ohhh, baby. Yeah. Haahhh...Lick it; lick the top...OH, YEAH RIGHT THERE!!' I pulled her knob between my lips and sucked on it gently. 'OH GOD! OOOHHHH GOD!! She couldn't wait for my cock anymore. She slid down and positioned herself with one foot on either side of my waist, and squatted down until her dripping pussy was directly above my hard dick. 'I'm gonna fuck you Mark. Let me show you. You'll love it. It's gonna be soooooo good...' She was babbling as she concentrated intently, grabbing my cock and pointing it at the opening of her hole. This is it, I thought. I'm going to fuck my sister. Dreams do come true.

She sat down onto the tip. Her vagina actually felt hot. She was so wet it only took a couple of tries to get my 9"-plus as far in as it would go. She groaned in ecstacy as I met her downward motion with a slow upward thrust. Wendy left her feet where they were; squatting over me she put her hands on my chest and started to fuck me. She was immediately going at it like a real pro, sliding up and down on my pole faster than I would have imagined that she could. 'Aghhhhh...Ahhhhh...MMM!' It was almost as if I wasn't there; just a dildo she could get off on. That was fine with me, because I WAS there and was I getting off, too...Her cunt was like heaven. I watched her bob up and down on my cock like a machine, her little titties bouncing, their tips diamond hard. I reached up and grabbed them and began pinching them. Not gently; not harshly. 'Ohhhhhhh fuck fffuck ffffuck fffffuck....' She was babbling again; lost in the powerful feelings of her artificially-created arousal. My sister raised one hand off of my chest and brought it over to her messy puss; while she fucked me like a maniac she massaged her clit with her fingertips. My balls, completely slick with her juices, were actually starting to hurt a little as she slammed the hell out of them. Her machine-like bobbing soon became erratic, spastic bucking as she brought herself off to a record breaking climax. She came while the entire weight of her body was resting on my groin; the entire length of my cock was pushed up inside her. But she wasn't finished with me yet. Oh no.

Wendy climbed off, knelt beside me on the bed and looked at my still-hard dick, throbbing for release. She slid it between her luscious lips and started blowing me again. I had been close to climax for a while; with my cock in her warm, moist mouth again, I was ready to shoot. I came in a little less than a minute. Once again my sister swallowed it all. After milking the last drops of cum from my receeding dick, she lay down with her head on my chest and fell asleep.

I slept for a while myself. When I awoke, Wendy was gone...I guess the Asian guy knew what he was talking bout when he said not to use too much; she was really on another planet for a bit...Facing her after this time was surely going to be difficult.

Wendy was avoiding me like the plague. She was probably beating herself up over what 'she' had done over the last few days, of course never realizing it was all engineered by me and the secret stuff I'd been using on her. One time could maybe be explained as a fluke; but after the second time...I think I may have used too much of it the second time, though. If I was going to continue, I'd have to be more careful. I decided to lay off and size her up before making any more plans.

We bumped into each other a couple of times around the house during the week but she was clearly uncomfortable. I tried my best to show her that I was still there for her, still her brother, her pal; it didn't' work. If she was this upset, I guess I'd have to stop. I didn't want to hurt her. I decided to ask her directly if she wanted to talk. Thankfully, she did.

'Well...I can't really explain it,' she said. 'I think I might be a nymphomaniac.' She said it like she really didn't beleive it.

'Can I ask you a personal question?' I gently asked.

'Sure..why the hell not?' The implication in her tone was, 'why not; we've been 'round the world, why not get personal?'

'Have you felt like this with any one else? Have you 'lost control' with other guys?' I knew darn well she hadn't.

'No! damn it! That's what is making this so hard for me to understand! It's just you! And you're my brother! We can't do this! I can't do this to you!' She was clearly conflicted.

'Look, Wendy. So you've had these 'urges' around me lately; I must admit I was a little weirded-out by this whole thing, but I'd be lying if I told you I didn't enjoy it. You know that. So if it's hurting me you're worried about, don't! I can handle what happened! If you needed something that bad from me, I'm glad I was there for you. No matter what it was!And I'm happy it was your brother that you 'lost it' with instead of some pick-up or something.' I lifted her chin to look into her eyes; she smiled weakly at me. 'So if I'm OK with it, then what's really bothering you about it?'

'I don't know...You make alot of sense, Mark. I guess, after thinking about it some more, that I only felt like it was wrong because society says it is. But if I didn't hurt you or myself, and these things happened between us willingly, I guess there's nothing to be upset over. I'll be OK.'

'Good.' I felt a little guilty about how confused she was, so I was glad I had made her feel better about it. I would lay off the stuff for a while, hoping that next time, she'd feel ok about it afterwards.

Well, 'next time' came the very next Saturday. I'm bad, I know. But I couldn't help myself...Wendy is just too hot to ignore for long, if you've got the secret to getting into her pants. And I did. It was in the afternoon; Dad was away on a long weekend opening up our vacation home for the season, out of state. The opportunity presented itself and I succumbed to temptation. The night before would have worked, too, but Wendy went out with friends. Today she was out with Judy, making up the lunch date she had blown off the weekend before. I gambled, not knowing if she had plans for the evening or not, and stayed in to see. I scoped out the fridge, seeing that, as usual, Wendy had a half-empty bottle of diet pepsi to finish...would this be a good place to put it? Or should I wait to see what happens if and when she comes home? If I put it in now, she definately wouldn't make plans for the night with anyone but me...I was just sprinkling some into the top of the bottle when I heard her car pull up. She was here. She entered the house wearing a flowered hat, a yellow half shirt, cut off shorts and open-toed shoes. Her bare legs were breathtaking. 'Big plans for tonight?'

'Nope; no plans...you?'

I lied and said, 'I might go out with the guys, I'm just waiting for a call. If not, maybe the gym.' I couldn't make it sound like I had conspired to be home tonight with her. I had to make it sound like staying home was the last thing on my mind. Then I noticed: she had walked in with a cup of fast-food lemonade in her hand! Damn! Now I had to try to get to that before she killed it. We small-talked about the mall, Judy, Judy's boyfriend; then Wendy headed to the bathroom. Bingo! I sprinted over to her cup and added the stuff; a little less than last time. I replaced the lid just in time...She came back into the kitchen and drank the remaining lemonade. Score. She asked me if I wanted dinner and I said I didn't. I told her I was going to take a quick ride to the store for some beers and a scratch ticket; I figured that when I returned the action would be about ready to start. What I didn't figure was, while I was gone, Wendy would also finish off her diet pepsi...with the initial dose in it. She had almost doubled the previous session's dose. Mercy.

When I returned, I didn't see Wendy anywhere. But I did see her big shiny vibrator sitting right on top of the couch, next to one of my porn magazines...let the games begin! I opened the fridge door to stash the beers and OH MY GOD!! That's when I noticed the diet pepsi was empty. Before I could consider the implications, I heard Wendy calling me from the bathroom. 'Marky? Mark, can you come here and help me with something?' I had no idea what to expect. I walked to the bathroom, opened the door...

There was Wendy, completely nude except for the flowered hat, sitting on the edge of the sink, facing me with her legs spread wide open. There was thick white shaving cream spread over her entire pubic area, a disposeable razor in one hand, and the water in the sink was running. She smiled sensually at me. She spoke very slowly. 'Hi, Mark. Could you give me a hand with this? I've never shaved myself before and I think maybe you should do it for me.' Oh, boy...She held out the razor to me and I walked zombie-like towards her.

'Uh, Wendy...Do you feel OK?' I took the razor from her. She had gotten a good bit of work done; about half of her crotch was shaven, still smeared with shave cream.

'Why do you ask, Mark? I feel fine! I feel fucking great. I'll feel even better if you'll help me shave my cunt...I'm shaving it for you, you know...'

Satisfied for the moment that she was OK, just super-sexed-up, I sat down on the toilet seat and started shaving my sister's cunt. She brought both feet up to the countertop, giving me full access to her crotch, all the way down past her asshole. Wendy reached down occaisionally and wiped the shaving cream and pussy hair away with a towel. I had never seen her pussy this close-up before, and it was a beauty. Big, meaty, pinkish-brown lips hung down from the sides; her clit was bigger than average and already swollen, no doubt from the dildo session on the couch. While I shaved, she talked. 'Do think my cunt is pretty, Mark? Now you can see my pussy-hole better than ever. And it's gonna feel soooo goood when we fuck...That's it, get everything...my asshole too...mmmmmm.....' She reached down now and again to give her protruding clit a little rub. 'See that, Mark? That's my clitoris. That's what makes me come.' She pulled it's pink cover back and exposed the whole thing; it was easily as big as a pencil eraser. I was sweating. I maneuvered the razor around her delicate areas as carefully as I could. In a couple of minutes I had her completely clean-shaven. She stroked the newly-shaved skin surrounding her pussy lips. 'Ooooooh, yeah, this feels so good...How does it look, Mark? Look good to you?' She rinsed herself off and showed me the entire package, opening it for me, pulling on the lips, rubbing it. I nodded, intimidated totally by the sheer sexual power that was coming off her in waves. I was her helpless slave. She looked me up and down. 'Why do you still have all your clothes on? You need to be naked like me. Let me see that big sweet cock. Take them off.' I stripped naked. My hard cock pressed up against my belly. 'Ahhhh...There it is...my beautiful big cock...Oh, Mark...Do you know how badly I need it in my cunt...my mouth..?' I felt like a little boy in front of this lusty, powerful woman. And she was my sister...She was in complete control of me.

She hopped of the sink. 'Let's go into my room and make each other come.' She led me by the hand into her room and turned on the light. 'Do you want me to suck it?' I stood there like a doofus. 'What do you want to do, baby? Tell your little sister and she'll make it happen.' It was like being in a surreal porno movie. While she awaited my answer, she pulled on the hard tips of her nipples. Her hips were very slowly gyrating as she stood before me, her bald mound incredibly inviting.

'Uh...I don't know...' My mind just wasn't working. Truth is, I did know. It was always a fantasy of mine. I took a deep breath, gathered my thoughts, and said it. 'Uh, I'd like to watch you...ah...play with youself.' I sounded like a complete idiot!

She laughed with that cute little girl giggle. 'You wanna watch your sister play with her pussy? Ok, baby, watch this...' Wendy lay down on her bed and spread her legs, revealing her clean-shaven cunt. She started rubbing her clit in a wide circular motion, closing her eyes and breathing loudly. I reached down and held my cock and squeezed it. She caressed her slick, hairless mound and inserted 2 fingers. I could hear them sliding in and out of her super-wet hole. I watched her titties moving around on her chest as her whole body gently rocked. Before I knew it, I was standing at the edge of the bed, between her open legs, stroking the length of my hard dick, my eyes focused on her cunt. Wendy's crotch was quickly becoming a wet, slippery mess and her breathing became moaning. 'Stick it in me, honey, stick that big hot cock in my cunt...fuck me....oooooh, fuck me Mark...' She held her big, wet pussy lips apart inviting me in. I bent down at the edge of the bed, grabbed her ass and pulled her hips slightly over the edge. I threw her legs up over my shoulders and entered her, fucking her bald pussy. The lack of hair felt great on my balls. 'Uhhhhhhh...You were so right, Mark, how could there be anything wrong with this...it's so good...I would die without your cock in me...ohhhh...' Soon, I wasn't going fast enough for Wendy...'Faster! Do it Faster! Fuck me harder...hhhhhhoooohhh....' over the next 5 minutes I did my very best. I fucked her harder than I ever fucked before. Wendy reached around and grabbed my ass and guided me in and out, trying to get me to go even faster; I couldn't! Could I keep up? She reached around and tried to find my asshole, feeling around with her finger; that gave me an idea. As she started to massage her cunt some more, I pulled my dick out. I was going for broke. Wendy looked up at me as if she were in pain. 'No! Don't stop! Put it back!' She looked up at me, pouting like a small child.

'Turn over. Show me your asshole.'

Her face lit up like a christmas tree. 'Oh, Yes! Marky! Do it! Fuck my ass! Ohhh yeah...' She quickly turned over onto all fours. Her brown puckering butthole was already slick with her own natural lubricant. I positioned myself behind her and put the head inside her tight little hole. She really freaked out, then. 'OHHHH! MARKY..PUSH IT IN! PUSH IT! YEAHHHH!' I slipped my big cock in further, and further...I had never buttfucked anyone before and now I was fuckung my sexy sister's beautiful round ass. Her asshole felt great; hot and tight; its grip around the length of my dick was tighter than any pussy I'd ever had. I looked down, watching my enormous cock disappearing into Wendy's impossibly tight butthole and she was loving every inch of it. 'FUCK MY ASS! YES! FUCK MY ASSHOLE! MMMMMM! HHHM! OHHMM! HHMMM! FUCK YOUR BABY SISTER'S ASS!' I could feel her pussy mound moving around; then I felt someting moving inside her, near my cock. She was fingering herself as I rode her ass. She was screaming; I was afraid the neighbors might hear! 'FUCK MY ASS WITH THAT BIG FAT COCK, MARK! SHOVE IT IN ME! SHOVE IT IN MY ASSHOLE, BABY!' After a few more minutes of frantic thrusts, she came again, the muscles inside her pelvic region squeezing and spasming like crazy. 'Ahh, Ahh, Ahh, Ahh...' It sounded as if she were weeping. But an angelic smile showed clearly on her face.

I couldn't take much more. I was thrusting into her ass almost as hard and fast as I had fucked her pussy. I started moaning, louder and louder with each thrust, and Wendy knew I would be coming soon. 'Cum for me baby! Give me that cum, Marky! Cum on my ass! Yeah, cum on my asshole!' I did just that. I pulled out of her tight hole and in 3 quick eruptions, I spurted thick white goo all over Wendy's beautiful butt. She felt it hit her and drip down the crack of her ass. She wheeled around, grabbed my dick and slipped it into her mouth, sucking out whatever was left and swallowing loudly. 'Mmmmmm, that's good...' Now she was looking at my dick adoringly, running her fingers over every bump, every vein reverently, almost worshiping it; she began showering it with kisses. 'I love you, sweety..mmmmm...I love you so much...' A second later I realized that she was talking to my dick!! She was slipping it in and out of her mouth, licking it like a lolipop, kissing and smooching it lovingly. 'You're so good, honey...so big and long; I love the way you fuck me...Ooooooh, my big fat cock...' I stared down, fascinated, and not a little worried. Now she was rubbing the head and shaft over her lips, her cheeks, her forehead, kissing and licking my balls. 'I need you in me all the time! I want you in my pussy forever...fucking me...fucking me in the ass...making me wet...making me come...I want you in my mouth, squirting your hot cum down my throat...' She had been babbling before, but now she sounded...deranged. She continued fondling and sucking my now flaccid meat until she lay her head in my lap...and fell asleep with my dick in her mouth!

We woke up together the next morning in her bed, arms around each other. We smiled at each other an kissed good morning. I had the usual morning stiffy; Wendy felt it against her thigh and reached down and grabbed it. Surely that stuff had worn off by now... 'I'm not going to fight it anymore, Mark; I can't win. This is a beautiful thing. I won't try to stop it ever again.' Wendy moved her hips over to mine. She lifted a leg up and over my side, pulling my hard dick towards her cunt. She was doing this of her own free will! 'This was just meant to be...' I had broken her, with the help of the stuff. We fucked slowly and lovingly, and not for the last time.
