After a pretty lean period I struck lucky when out perving yesterday.

After a frustrating half hour under the bridge which the high school girls cross coming out of school, I had seen no knickers. Although the skirts are short, they seem now to wear very dark tights, thus preventing me from from peeping. Disgruntled, I wandered down to the local park where in a secluded corner I spied a young couple, the girl having come from the aforementioned high school. I could hardly believe my eyes. She had her skirt up and her tights and knickers down. She was bent forward with her hands against a tree. The young lad had his trousers and pants around his knees and was thrusting into her from behind. I crept up as close as I dared and watched from behind a park bench. My excitement grew and I had to pull out my penis and wank it in time with the young guys thrusts. Both of us moaned as we released our cum more or less simultaneously, the difference being that mine was thin and watery whilst from what I could see as it dripped into the girls knickers, his was thick and creamy. The girl and boy both pulled up their underwear and adjusted their clothes and I quickly wiped my trousers where some semen had dripped. I immediately sat on the bench while the young couple walked right past me hand in hand. I wanked again when I got home.
