Sister-in-law Fun

I had been biking and when I came home Cindy was talking with my wife at the kitchen table. I came in and said hi and went to the couch and started surfing on the internet while they talked. I never noticed much about either my wife or Cindy as they were deep in conversation. So I checked in here on solotouch and was watching in a chat room and was slowly getting aroused. I had forgotten I was in biking shorts and they were tight. I slowly started getting an erection. My shorts didn't hide much, but I still wasn't paying much attention, until I looked up and caught Cindy staring at me. She was still engaged in conversing with my wife but I saw she had positioned herself to watch me, and she was staring at my engorged penis. I didn't know what to do at this point as there was nothing to throw over myself, so I could do nothing. I acted dumb like nothing was happening and continued as I was.  I was getting turned on, but could do nothing. I couldn't help but notice how Cindy kept looking at my hardon. She was fidgeting slightly, but kept talking with my wife. By now I am so turned on I can't stand it. Sister in law sex is a no no. I wouldn't even consider it. So, finally I got up and ran to the bedroom. I jacked off and when I could, dressed and came out to the living room.  I joined the conversation and acted like nothing was going on. Cindy was friendly and acted like nothing was out of the ordinary. When she left we said goodbye and as she left, she gave me a sly smile and winked. Well that was it, I thought. I never gave it another thought. I dismissed it out of my mind and wouldn't allow myself to dwell on it. O  A couple of days later Cindy showed up and asked to talk with my wife. She was out doing the grocery shopping and I told her so. She asked if she could wait for her and of course I thought nothing of it and said sure. She took her jacket off and holy smoke. She was wearing a yellow tube top that barely contained her breasts, a short short mini skirt. As she sat down I saw she wasn't wearint any underwear.  I immediately realized that this wasn't going to happen and I would not let anything happen. Not with family, never ever. We chatted briefly and I realized quickly I was getting so turned on I needed to get out of there. Damn, she was so hot. I could'nt keep my cock down. I was so hard. I am a large dicked man, so it shows. I had to excuse myself and told her I had to lay down and take a nap, but she could watch tv until my wife came home.  I went into my bedroom and shut the door, but didn't shut it all the way, it was cracked a very little bit. Laying down on the bed, I slid out of my shorts and my cock was rock hard. I now had this fantasy about Cindy and slowly started masturbating. Very slowly, I didnt want to cum fast. I heard Cindy walk past the door and go to the bathroom. All right I thought. I closed my eyes and kept on masturbating. I was huge and leaking and my thoughts were running amok as I was thinking of fucking Cindy, something I had never had cross my mind. All of a sudden I hear a gasp and an omg. She had pushed the door open and was watching me. Her mouth was open and she was staring at me. I didn't know what to do. I immediately just stopped and held my cock. I didnt know what to say. Cindy just kept saying omgomg. I can't believe you are really that huge. Her hand was under her skirt between her legs. I don't know how long she had been there. I start stuttering about how sorry I was. She came over to the side and without saying a word put her hand on my cock. My god, she said. You are so fucking huge. How does my sister take that! Fuck, I have never seen any cock that size!  I am petrified as I don't know what to do. So I just lay there, her hand running up and down my cock. She just kept saying, omg, omg. I can't believe you are so huge! She slid her top off and crawled onto the bed. She said she had to have it. I am thinking, this can't be happening. She told me she saw it the other night and just had to see if it was really that big. She was allmost drooling over it. I have to taste it she told me and she put the cockhead into her mouth and slowly started running her tongue up and down and over the head. She lowered her pussy over my mouth and I decided what the hell. I softly licked her slit as she sucked my cockhead . God she said, I can't get hardly any cock in my mouth. I started licking and sucking her clit. Sliding the clit side to side with my tongue. She was going crazy. Eat me she screamed, I worked her pussy for 10 minutes as she tried to suck my cock. I was so turned on and so stiff and ready to shoot. She had cum several times and was so wet. I need that cock in my pussy she passionately whimpered. She turned around and tried to sit on it. Her tits were right in front of my mouth and they were perfect. I started licking and sucking them. Feeling them stiffen in my mouth, I went from one to the other. She was fitting the cock head into her pussy, forcing the cock deep into her. Omfg she kept saying, I can't believe I am taking this monster. Fuckkkkkkkkkkkkk. She just kept saying fuckkkkkkk over and over as she drove all of me deep into her. She started shaking and trembling, her legs shaking as she rode me up and down. Her eyes shut and head arched back. I am twisting her tits and thrusting as I can't believe this is happening. Don't cum in me she starts screaming but she just keep fucking me, milking my cock. Don't shoot in me she yells. God, I am so fucking turned on at this point I can't think. FFFFffffuck I start yelling, I am going to cummmmmmm. Instead of getting off she just keeps fucking furiously and moaning and whimpering, her body shaking and trembling. She won't quit fucking and I can't help it, and I shoot and cum and cum and cum and I just keep shooting deep into her. She really lets loose and has an orgasm the like of which I have never seen. She is screaming and cumming, my cum dripping out of her pussy around my cock. She collapses on me and stares at me. I softly kiss her and she kisses me back, very passionately. We can't tell anyone about this.

I agree with her and I watch her as she cleans up. God she is beautiful. I am wondering what happens now. This can't happen again. She comes back into the room and we chat about how no one can find out about this and it can't happen again. I was in a state of absolute bliss and still naked. She took my cock in her mouth and started sucking me again. Her hand was jacking me hard. She told she was so sorry about this, but she can't get enough of my cock. I told her, we can't do this and she agrees. After all is said and done, she  leaves before my wife gets home. This just happened and I don't know what will happen if anything happens like this again. I had a real life fantasy and never thought anything like this would ever happen to me. Maybe it will, who knows?
