Cock masturbation wearing a steel ballstretcher and binding testicles between legs

Description: I love the feeling of my testicles being pulled and i want them to reach my knees soon... all i have to do is masturbate constantly with as much weight as possible hanging from them. after wearing my steel 9.5 oz. ballstretcher for all day, as soon as it arrived at home, i couldn't wait to leave my balls free and see them dangling... but i'm not satisfied with the stretching and therefore while i masturbate, i bind my testicles between my legs in order to pull them stronger: while i enjoy this pleasure,i pour a hot rain of sperm everywhere!
