I used some old socks and underwear, some of which I threw in the garbage. I must confess to an early fetish here. I had a next door neighbor Mennonite boy about my age who I played with occasionally. He was a hung, lean dirty blond. We were about 15 or 16. He used to spend time working at his grandfather’s farm and used to wear those green rubber work boots. He’d leave them on the back steps to air out. I would surreptitiously grab them at night and smell the inside and then rub my cock up and down the rubber sides and leave a big white mess, which I’d clean up before returning the boots to the steps. If he only knew! I’ve had a boot fetish ever since.
