My family had just moved to Las Vegas into a family members previous house. He had left a Playboy in the closet. I had just turned 13. I had been looking at Playboy, Penthouse, Hustler, OUI, etc, for years, but never had an orgasm while looking at them. I always got an erection and rubbed myself, but never to orgasm. The first night we were in our new house, I grabbed the Playboy and went into my walk-in closet. There, I looked at the pics of the naked women and rubbed my cock on the inside of my thigh. It felt good. I continued rubbing and I felt this weird sensation. I kept rubbing and all of a sudden, I came. I only ejaculated a small amount, about the size of a dime, because I stopped. I thought I broke something! Scared the bejeezuz out of me. It finally occurred to me what had just happened. The next night, and from then on, I masturbated as much as I could, and anywhere I could. My favorite place was outside on top of the garage patio. To this day, I still like the feeling of cumming while outside.
