This incident happened last year between me and my cousin sister Nisha. This story is a bit long.I am a computer engineer as well as nisha. We both ar... from Nagpur. I have a slim body, moderate looks, fairly tall and wheatish complexion. Nisha is a bit short, chubby, not too fat. She has a wheatish complexion and has a stunning figure (will make any guy look once again at her). Nice round boobs and fairly big buttocks. Speaking of mine and her relationship, we were not that great in touch. Just. "My god they're nice. So cute!"She undid my jeans and let them drop so I could step out of them. Carefully I unclipped my stockings and slide them off. I pulled down my panties but left my tiny g-string on. When Cheryl asked me about them I explained how they help prevent my balls and cock from falling through the leg holes of my panties. "Not much there though." Cheryl fondled my junk and stroked me to an erection. "Balls are pretty small. And you really can't call this a cock. It's maybe four. I figured she went to the store. But I was wrong she had a date with Mr. Walker to go down by the river for a picnic. I found this out from the store manager when I arrived there an hour later.I did not feel right about this so I drove out the river and parked away for his car. I made my way down through the trees and found them on a blanket in the shade of a large Oak tree. He was on his back and Mom still fully dressed was a straddle him. I guessed she was naked under that dress and his cock. He pulled back to slam home and he looked deeply into my eyes as his cock bolted into my pussy, spreading it to its limits. I was so full that I couldn’t move. He didn’t bother to fuck slow and ravaged my cunt with his glorious member. He was whispering in my ear, but his words became lost in all the pleasure. I felt my orgasm start to build. I started screaming in ecstasy, not caring whether we were caught. His hand covered my mouth while his other ferociously worked at my clit. He fucked me.
