After a long day at the pool, Biflatmate and Shyflatmate retreat to their private shower room, their skin glistening with sunblock and chlorine. The air is thick with an unspoken tension, their eyes flicking from one another's toned bodies to the bulges straining against their swimsuits. Biflatmate, emboldened by his roommate's bashful glances, kicks off his sandals and steps closer, his heart pounding in his chest. He reaches out, tentatively tracing the outline of Shyflatmate's fat dick through the damp fabric. Shyflatmate gasps, his eyes widen, but he doesn't pull away. Encouraged, Biflatmate guides his roommate's hands to his own long, uncut cock, and together, they stroke and tease each other, their bodies pressed close in the cramped space, their breaths coming in ragged gasps until they're both desperate for more.
