Dirty trick when I was a kid
I grew up in a trailer park and there was a play ground. It was sort of enclosed by the slide. A roof and walls. Sometimes I'd go stand in there and if one of the boys wanted to go down the slide, I wouldn't him pass until he kissed the crotch of my shorts. And if he didn't kiss hard enough for me to feel, I made him do it again. I was only about 9-10 and I just new it felt good and was kinda dirty.
