Teen Babe Straps Down Customer For Release Rub

This guy wanted a release massage and the teen masseuse is about to get mean upon the request. She's been looking for a chance, bad for the poor guy. She straps him down and starts stroking his cock really hard and painfully, denying his orgasm as long as she prefers...He's been left to lay helpless on the massage bed. How long would a man suffer like this?
