In the privacy of his room, a man, known only as "Cum 4," indulges in a private, solitary dance. His eyes closed, he explores his body, fingers tracing lines of pleasure. His breath hitches as he strokes himself, the rhythm building, a symphony of sensation. He's lost in his own world, a world of touch and sensation, as he brings himself to the edge and then, with a final, shuddering breath, tips over into release.
