I'm assuming everyone here masturbates. Would you do it with or in front of anyone? Yes I'm sure we would all draw the line somewhere when the standards are not acceptable. But would you do it in front of or with anyone, even strangers?
It's never happened to me but I live for the day someone, anyone, asks if they can see my cock and watch me masturbate. Bonus points if they would join in. Lots more bonus points if they were the opposite sex.
