I used to fantasize about an older man when I was 18. He was a family friend who was married, and I really liked his wife, but there was something about him that was so sexy. He was almost 40, but he was so confident, possessed, and whenever he was over I found myself looking at him. He would look at me as well, and we would spend long moments with our eyes locked, and we would smile at each other.
One night, he was over and our whole family was watching a video on TV. I was lying on my stomach in front of the easy chair where he was sitting. The rest of the family was on the couch, so that he and I were slightly behind them out of their view when they were looking at the TV. The lights were out, so we were only lit by the glow of the television, and about halfway through the movie he put his foot on the back of my thigh.
He was resting it there, on top of the blanket that covered me, and I immediately lost all concentration on the movie, only aware of the warm feeling of his foot on my leg. After about five minutes, what seemed like forever, he slowly moved his foot along my leg so that his toes stroked the back of my butt, and then back down my thigh all the way to the back of my knee. He moved casually, as if it were no big deal.
