A sexual position, often used by prostitutes of either gender that don't want to be penetrated, but most commonly by pre-op transsexuals, that involves the john rubbing his cock between either the thighs or less frequently, the butt cheeks of the working girl or guy, until orgasm.

Similar to tit fucking. Mostly used in Australia.
