Watching this again now, it's a shame he couldn't have gotten his pants down where he could have enjoyed it a lot more and not had to deal with the sperm. It's what I would have done if at all possible.
I think so too. He was obviously horny and needed to masturbate. It wasn't really risky and he had more than enough discretion I think. Hopefully he can disguise/do something about the mess in the front of his pants. That would be my only concern. Otherwise, my dick and I enjoyed doing it along with him!
