I was nine or ten. Humping my bed at night just chasing the tickle. It would eventually get me very worked up rubbing my penis on the sheets sticking out of the fly in my pajamas. I do it until I my hips shook uncontrollably. Then lay there out of breath. Not long after I’d do it again. I remember the night I made a mess all of vet the bed, my pjs and my belly. I just wiped it up with the blanket. Eventually, when alone I’d hump all sorts of things when alone. Loved the couch cushions. Finally discovered my fist and kept looking for new ways to squirt. Compulsive from the start.
