Biflatmate, fueled by alcohol and bravado, decides to liven up a late-night stroll with a surprise for his twink roommate, Shyflatmate. Under the cloak of darkness, he unzips and lets loose a stream of warm piss onto Shyflatmate's round, pert ass, clad only in tiny shorts. The shocked but aroused Shyflatmate squirms and moans, loving the exhibitionistic thrill and the feeling of piss cascading down his smooth, white skin.
