Fist pumping a swollen cock right above the bathroom drain, the hand grips tight and strokes fast while precum drips into the grimy metal grate below. Shaft throbs hard, veins bulging as the pace builds relentlessly with each upward tug and downward slide. Pink head glistens wet, hovering inches from the drain hole where earlier spurts already pool and swirl. Tiles gleam slick around the edge, black shoes kicked aside nearby with white fabric draped over the floor. Hand squeezes the base firm before speeding up again — cum erupts in heavy bursts straight into the drain. Ropes cling to the rim momentarily, then wash away down the pipe as the spent cock twitches one last time over the soaked surface.
