I laughed as I threw his shirt into a corner, he was so silly. This was the Will I knew, goofy and outgoing. His belt came next, and he looked at me w...th a dark smile as he snapped it a few times. I jumped with each sharp snap, remembering how it felt when he had spanked me so hard the first time we were together. And how wet it made me. Suddenly, an image of myself naked and bound laying across Will’s knee, moaning and wiggling around as he rained down sharp blows on my tender ass with his. He told me he got to look at herface when they were having sex. WELL, THAT LITTLE BITCH! I screamed thatin my head! This boy girl relations crap is really messed up! Here I wentand put on some of my sexiest undies, and satisfied him with a really goodblow job and then he probably goes and has sex with her. Now I really wascurious. Who was he going to invite to the prom. I think we all know thatsex is kind of assumed on Prom night. Here I was thinking maybe we'd spenda romantic night in a hotel,. My sister in law was stripped naked exposing every private part of her sexy feminine anatomy unknowingly to me, her brother in law of 20 years. Again I was able to examine her nude body intimately from head to toe while she stood facing me drying her hair. Starting from her perfect feet I examined her fine ankles and her surprisingly slender slightly hairy lower legs. Above her knees her legs became thicker leading towards her chubby blotchy thighs. I had never seen her legs uncovered. They were having such a good time that I had to wait for about fifteen minutes while they finished the game they were playing. Even then it was difficult to settle them down enough to get them buckled into their seats in the car."Where are we going, Daddy," they asked?"Wherever you want to go," I replied."Can we go to McDonalds? We really like the shakes there, and the kiddies meals are yummy," they said excitedly.As I looked at them in the rearview mirror my heart went out to them. They did.
