My name is John, now 26 but at the time of this occasion I was 21, the same age as my stepsister Vicki. My dad remarried and I didn't get along with Vicki at first. We were always fighting and neither one of us liked our parents getting married again. Usual teenage bullshit. Eventually we got along and started making our new situation work. I remember when we were both 19 we started staying up late in each other's rooms and partying a lot. Vicki was looking damn fine and we began flirting a lot. She had long blonde hair, which she wore straight, and the best part, real big tits. She dated a lot, guys were always after her no doubt for those big titties. She dressed the part too, she liked showing her body off by always wearing skimpy clothing in the summertime. I am no slouch myself, I workout and am in good shape. I have black hair and blue eyes and a muscular build. My cock is average at 7 and half inches but nice and thick. Our flirting was getting a little hotter as time went on, I would actually squeeze Vicki's tits sometimes and she'd always go for my balls when I did so. More just playing around nothing serious. One weekend in July our parents went away for a few days on vacation and me and Vicki had the house all to ourselves. Oddly enough neither one of us had plans and Vicki kept saying how she wanted to go to a club. I didn't really want to go but after hounding me constantly I agreed to go out with her. There was a pretty happening club only a few miles from us, which would be in Illinois. When it was time to leave Vicki came downstairs and the way she was dressed was unbelievable. She had super short black shorts on with a very low cut white and black patterned top on, her tits were almost damn near exposed completely and she wore these killer open toed platform heels with an ankle bracelet. Her toes were painted hot lavender and her fingernails are always that french style with the white tips. Stepsister or not I got very hot just looking at her. The club was packed and Tequila is both our choice for booze so we got a couple of margaritas right away. We downed like 3 in a row and I was getting a little buzz already. We were there for almost an hour and a half and Vicki couldn't stand still moving to the beat of the techno music that was being blared. She grabbed my hand and said she wanted to dance. Fortunately I can dance and we went out on the packed dance floor. Vicki gets crazy when she dances like most girls and was really gyrating her hips and getting into it. She turned around with her back to me and I held her hips and she put her ass right into my groin area and grinded all over my cock, which started to get hard. I had my hands around her on her stomach and she reached back and put her hands on my hips and really grinded hard into me. We danced for another song and had a couple more drinks. Vicki and I were both pretty buzzed now, we had had about 5 drinks each and the dancing got a little hotter. She grinded again on my now rock hard cock and my arms were around her and my face was in her neck and I breathed purposefully on her neck to see if it turned her on. She had her hands on my hips but this time she moved her hand to my cock and began to rub it. No one could see because we were dancing so close together. I put my hand on her ass and rubbed it a little. We were flirting big time now. We left the dance floor, had one more drink and Vicki said she wanted to go home. I drove slowly home being pretty blitzed and when we got home Vicki turned the radio on and started dancing with me again. She was totally coming on to me, she bent all the way down and grabbed her ankles while pushing her ass right into my cock. I held her ass and thrusted into her as if we were fucking. She stood back up and I cupped her big tits and she didn't do anything. Her nipples were hard and she turned and kissed me. We kissed for a minute and she took my hand and pulled me into her room. I sat on the bed and she unzipped my pants and pulled my shorts down and immediately went for my cock. Man she was sucking my cock like an expert and I was going crazy. A few minutes later I had to pull her off me and I took the rest of my clothes off and helped her off with hers. When her top came off I had to suck on those monster tits. Wow they were big and I sucked them and nibbled on her nipples. I couldn't get enough of them. I had to taste her pussy which had not a hair on it, it was shaved completely clean so I pulled her over my face so she was straddling my head and I spread her pussy lips open and drove my tongue inside. She was wet and juicy and I slobbered all over her cunt lapping up all that pre-cum. I knew Vicki had a little bit of a reputation as being an easy lay and I wondered as I lapped at her pussy just how many guys she had fucked. Strangely that turned me on even more. Vicki was moaning and playing with her tits and then she spun around so she could suck my cock some more. Now we were engaged in a very hot 69. I licked her pussy and had her ass cheeks spread apart and thought I'd try to lick her asshole. I started running my tongue up and down over her asshole and she really loved it because she clamped her mouth even tighter around my cock and was really deep throating me. Believe me, I should have blown my load by now but thankfully liquor dick kept me going strong. I rubbed my finger over her asshole and started to push it in while sucking her juicy cunt lips. I ended up sticking another finger in her ass and was now shoving two fingers deep into her asshole. She ended up cumming all over my mouth and chin, soaking it in wet pussy cum. She was sucking my cock like crazy and I tensed up and she pumped it hard with her fist and I exploded in her mouth. I came the hardest I ever have and she gulped down every single drop. She rolled over and spread her legs wide and told me to fuck her. I placed my cock against her pussy lips and pushed it in before I lost my hard on. It was a little sensitive at first but in a matter of minutes I was fully hard again and her cunt lips felt soft and warm on my cock. She put her legs up on my shoulder and I fucker her as deep as I could. Her tits were bouncing all over as we fucked, that was a sight I can't get out of my mind to this day. She came again this time all over my cock. I started pumping her slowly to let her recover and she pulled away from me and grabbed me and pulled me back into the living room where she got on her knees on the ottoman and put her head in the chair basically she was crouched down with her ass in the air. She spread her cheeks apart and I pushed my cock against her asshole until it slipped in. Man it was really tight but I knew she had done this before now. She was moaning real loud and I got a good rhythm going. I slammed into her asshole for a good ten minutes, she had cum again and now I was ready to cum again. I pounded her asshole extra hard and held my cock still, deep into her ass filling it up with cum. I pulled my cock out and rubbed it over her ass cheeks. She wanted to fuck all night but I only managed to get it up one more time later that night and ended up cumming all over her pussy lips. I pulled out right when I started to cum and coated those juicy lips. She wanted more but I gave all I had. There were many more times we had like these until she got married and all the fun stopped.
