A friend and I masturbated each other on a very crowded commuter train a few weeks ago. As far as doing myself? In the back of a taxi while the driver was watching in the mirror. The ride was free for some reason.
I've jacked of in class, I got a boner and I just started tapping my leg really fast and I just cummed. It felt so good, I imediatly went to the bathroom to clean up. luckily it didn't seap through my pants.
At the beach (it was a lake, so you couldn't see under the water), and yesterday in a field right next to the woods. There was a road where I could be easily seen, but also I could hear the cars coming long before they could see me so it was safe... or so I thought. I think two cars might have seen me. Then like 30 seconds after I finished some old man walked out of the woods to where I was.
i gave a guy a hand job during class and at the lunch table were all our friends were sitting there having lunch ... it was kinda funny ... they had no idea until i told them....lol
