I had been masturbating several times a day for a while. I asked him one day if he jacked off. We had been talking about girls on tv and ones we knew....Then I snuck some Playboys from my dad's stash. I could see the bulge in his pants and knew the effect the pictures were having. Then I upped the ante and pulled out a Hustler from dad's stash. The graphic pictures of the spread pussies and assholes had the k** groaning and a wet spot was forming at the end of that bulge in his pants. I told him. I was a boy, but I looked more like a girl, and even acted quite feminine. The older girls would use me as a dress-up doll, and the older boys would beat me.
