Blanket Rubbing

When I was younger, first starting to masturbate, my penis was very sensitive. I was probably 13 or 14 or so. I would lie in bed, take my blanket, mainly just the sheet, because it's thinner. Put it between my legs, and rub just the head of my penis on a flat surface of the sheet. It would almost give a rugburn sensation, but it felt so great. Felt like I had to pee real bad, but I just kept going. I would start to go faster and faster, eventually burst into the most powerful orgasm a young boy could have, making a mess all over the sheets. I wouldn't worry about catching my cum with a towel or anything. It felt so erotic and I was so horny I didn't care where the cum went.
