In the privacy of the bathroom, a man stands, his balls heavy and wet from the shower's spray. He takes his cock in hand, stroking it with a practiced rhythm. The water pounding against his back adds to his pleasure, the warmth mimicking the heat of a mouth or a pussy. He groans, his hand moving faster, the sound of his pleasure filling the room. With a final, shuddering breath, he comes, his cum mixing with the water at his feet, swirling down the drain as he continues to stroke, milking every last drop.
