I can remember being 16 and finally succeeding in getting my best mate's father to have sex. He was divorced and the women were never around long or often. Their back fence was the school fence so i would leave my bike at their house and go to school from there.
One morning, I was skipping first class for some reasona nd smoking under their house - it was queensland and the houses are on stilts/poles. When his father came from work un-expectedly. He didnt mind me being there - we were always at their place. He stood talking to me and i can remember seeing his outlined in his trousers. I thought - most probably imagined his cock was slowly getting a bit ahrd. I sprung a boner and there was no mistaking that in my school shorts (we were shorts all the time because of the heat).
He kept talking but then did get hard. I rememebr putting the smoke out and then reaching straight across to stroke his now hard cock - mine was dripping like a faucet and there was a nice wet patch on my shorts.
He sighed, push my hand harder on his cock and suggested we go upstairs and have some fun. Fun we had. He wasnt my first sex encounter but was one of my wank fantasies every night for years before and still now.
