We started going at each other hard. She reached down and grabbed a hold of my cock which was hard as a rock. "My sister let this go, she is stupid" Sam said commenting on the size of my cock. She rolled herself on top of me and was sitting on my midsection. I looked up at her as she removed her top. Her tits were perfect. My Ex had nice ones but these Playboy quality. Perfect in every way. Hard, big and round with nipples that were in just the right place. My mouth went dry but not for long as I knew I had to get it on those babies. I pulled her down on top of me and went to town on her tits. While I was doing this she was ridding us of our underwear which was getting in the way. After she had had enough of me playing and sucking on her tits she smiled and said "I know what I want" and with that she went down on me.
She gave me the best blowjob I had ever had. She was bobbing up and don on my pole and I could feel my balls tighten, I knew I would blow soon. She must have sensed it too. She pulled away and rolled on to he back and told me to fuck her big tits. I didn't have a choice. I put my dick between those globes and squeezed them around my cock. I started thrusting between them. The feel of Sam's perfect mounds wrapped around my cock was great. Each time I pushed forward her mouth would wrap around the head. I was getting that feeling again I knew I would cum soon and told Sam that I was going to blow. " Let me swallow it" she said. Like I would argue. I unloaded in her mouth and she didn't waste a drop. all of it right down her throat.
It was now her turn to get some of this. I put my head between her legs and began to lick and lavish the whole pubic area with my tongue eventually getting to her hot, now very wet pussy. I liked up and down her slit and she started moaning like crazy. I focused my attention on her clit while I began to finger her pussy and her ass. She began to tremble and I knew she was close. I kept going on her clit and stuck my finger right up her ass. This put her over the edge and she was bucking her hips and screaming. After she calmed down Sam said "Now I really think my sister is stupid".
I was hard again so I knew what to do. I got on top of her and slid my dick into her pussy. We started fucking and it continue for quite a while in a few different positions. She was on top, then doggy, the spooning her. She started to cum again as I was rubbing her clit while fucking her hole from behind. She was again screaming and moaning loud. and this action plus the spasming of he cunt muscles was bringing me close. I told her I was close and was going to cum. She told me " Take it out and cum in my mouth, I want your cum". Again no arguments from me I pulled my cock out, it was soaking wet from her juices, and I came in her mouth with my second huge load of the night.
We lay there afterwards talking about how awesome that was and how bad we were. I looked at Sam and said " You know we may never be in this situation again, maybe we should make the best of it and do it again" She laughed and decided I was right and we continued to fuck and fondle all night long. Sadly it was the only time it happened but there is always the other sister, Brenda. She and her family are coming to visit me next week...
