A lone Japanese man, in the throes of self-pleasure, strokes his rigid cock with urgency. His breath hitches as he feels the familiar tingle, his body tense with anticipation. The room fills with the sound of his eager hand moving up and down his length, the scent of his pre-cum permeating the air. He lets out a guttural groan as he reaches his peak, his body convulsing as he paints the room with his hot, sticky seed.
