The sound of the shower running echoes through the empty apartment, beckoning the lonely resident. Naked and hard, he steps into the steamy enclosure, his dark skin contrasting against the white tiles. He begins to stroke his stiff cock, his hand moving in sync with the rhythm of the water. The heat and the sensation overwhelm him, pushing him closer to the edge. He leans back, his body tensing as he spills his load, the warm cum mingling with the cool water, a taboo release in the sterile, clinical setting.
