I tried making a few videos of me stroking myself to a nice cumshot and posted them on xhamster. It was kind of a hot way to be watched by people who wanted to watch. Kinda cool because people can leave comments etc. found that most were gay guys which was fine, but I definitely would prefer to be watched by women. Each video made while having a nice cocaine high.
Would be hot to do it live though!
One time in the library at university I was hard as horny. There were lots of study group rooms and i was in one. A girl I knew was in the room too and we were chatting and flirting a little. Under the table I let my hard cock out and started to very slowly stroke myself. It was very hot. I had to stifle the need to make noise and moan. I did end up cumming and releasing a big load onto the carpet. This was all while chatting and she seemingly had no clue. Very hot.
