Riko, a restless, horny young man, finds himself alone and in dire need of release. He locks his bedroom door, stripping down to his briefs, his cock already straining against the fabric. Sitting on his bed, he strokes his length, his breath hitching as he feels the familiar pleasure build. He pushes his briefs down, freeing his cock, and continues to masturbate, his hand moving faster, his grip tighter. He lets out a low moan, his body tensing as he finally finds his release, his cum spurting onto his stomach.
