On the Tube

When I was in my teens I had a music lesson on Sunday mornings. One time I was on my way home from my lesson and started feeling really horny. I was sitting in my favourite seat � the one end of the carriage � and I could see there was nobody else in this carriage, and behind me was the windowless partition against a driver's compartment. I unzipped my flies, slid my hand inside my jeans and started wanking steadily. My erection felt delicious, lovely and warm and smooth in my hand. I was soon getting near the brink and slid forward until I was sitting on the edge of the seat, with my legs angled downwards, with my knees nearly on the floor. Then on the spur of the moment I pulled my erection out my flies. I cupped my free hand under my balls and a moment later I orgasmed, shooting my semen all across the floor and the back of the seat. I've always felt a bit guilty about it, but boy it was wicked. Wicked.
