#372991 - I came to the conclusion that he was perhaps too conscious of the fact that we were in the middle of the train and he felt too exposed to risk the kind of “shenanigans” we had played the other day. I continued this action slowly, up and down, up and down, up and down until, all of a sudden about a minute later, I felt a little jolt as his bum thrust into my own groin as he clenched forward slightly. As he did, I felt his rock-hard organ throbbing in the palm of my hand, expanding and contracting rapidly five or six times as what seemed like pints of warm, sticky cum filled the palm of my hand and ran between my fingers and back down the shaft of his organ into the soft cotton material of his underpants.
