Boxing Yul Brynner
stimulating your penis with your hand or hands to cause orgasm and ejaculation. Male masturbation.
Putting his fists up to engage in a round of rubbing one out he notice that his cock kind of looked like Yul Brynner's Bald head from behind as he start to stroke..... Just then I get a call for one of my buddies they ask, "waz up"? and I say, " just sittin' around BOXING YUL BRYNNER".
