My sister in law is opposite of my wife, she's petite, 5'4", nice round ass and big natural tits, 34D. She loves clubs and has a new boyfriend all the time. Since she's single and younger,26, than my wife, Liz, 35, she doesn't hang out with quite us a lot. She dresses very provocatively and likes to feel sexy. One night we were out dancing and drinking and as she was dancing with me my dick was getting hard and she felt it at one point and pulled away from me, surprised to feel me excited but a few songs later she started moving against me and rubbing her ass discreetly against my hard cock. I felt guilty and told her I was sorry, she said: I don't know what you are talking about, nothing happed"; since that day she looked at me differently but we had a good relationship nonetheless.

A few weeks later, she was out drinking and lost her hey to her apartment. she called my wife around 2AM to get her copy since we live nearby. My wife asked me to take the key to her because she was very tired from a dinner party we had attended earlier. It was summer time and I left my house wearing sleeping short and a white t-shirt. When I got to her apartment, Jen was asleep at her apartment door wearing a blue mini dress showing her beautiful legs. I helped her get up and open the door, when we got in she told me that her legs felt sore and bruised and she could not remember how she got hurt. I asked her if someone had try to touch her and she kept saying she couldn't remember. I called my wife to tell her what was happening and she suggested Jen should take a close look as her whole body to make sure she was not hurt in other parts. When we hung up, Jen removed her dress and her braw right in front of me and asked to to check her to make sure she was fine. When I saw there naked body, just with her black thongs on, I got a hard on that was very visible through my shorts, my cock is 8.5 inches and very thick so its very hard to hide when is very hard.

Now, Jen was drunk and tired but she couldn't take her eyes away from my crotch. I told her she looked fine and she should go to sleep. she told me "I wish you could stay with me so I can feel safe" I said I would help her to bed and go back to my house. When I took her to her bedroom she asked me if i could massage her legs a little bit before leaving. She laid in her bed still wearing only her thong, I tried to massage her legs and my excitement was driving me crazy but I knew i could not make the first move. I asked her if she wanted massage in any other part because it was getting late and I hat to leave. she looked at me and said: "I think you need a massage somewhere, apparently my sister is very lucky" I asked: what do you mean?" and she replied: "I see a huge mountain in your shorts and I want to massage it to return the favor" I tried to leave bet she grabbed my host and pulled me close to her. She lower my shorts exposing my big dick hard as a rock. I said: "ok you can only massage it and i'll leave" she said "ok" and started giving me a nice hand job. After s few minutes she said: "I don't think my sister would mind if i give a blowjob since you have been is nice to me tonight, and put my dick very slowly in her mouth. Her tough and red lips felt so good! she told me: "this is the nicest cock I've ever sucked, you have to fuck me" I said: "no way" but she said "well, we already cheated, do you think my sister would not consider what we've done cheating?" At this point I wanted to fuck her badly but felt very guilty. She removed her panties and told me: "ok, just the tip of that huge dick in my little pussy and you can go, I know since that day at the club that you want to fuck me".

So here I am with a raging hard on and my Hot sister in law naked with her legs open showing me her shaved pussy and beautiful tits and begging me to fuck her. Horny as fuck, I said "ok, just the tip" and i put the tip of my dick in her pussy, she pulled my body towards her and kissed me deeply inserting her thong down my throat and telling me to get a little more inside her. I refused and she kept kissing my neck and sucking on my nipples, now I was about to explode. She said: get the rest of that dick inside my pussy or I will tell my sister you took advantage of me" I had no choice and penetrated her all the way, her pussy was so hot and tight, she was moaning and screaming like she was in heaven. She was a great fuck and loved talking dirty, which i love. she was telling me: "best cock in the world, my sister is going to have to share you a lot with me, you are making me cum so much". I fucked her for about 30 minutes and exploded inside her messy pussy. She thanked again my with a passionate kiss and I went back home to my sleeping wife. The next day she called to to say that she could not walk because her legs and pussy were sore and she needed another massage session.
