Prudence, lost in the lyrics of his favorite song, lets the music guide his hands. He's alone, but the beat is his companion, his rhythm. His cock is a willing participant, hardening at his touch. He grips it tightly, matching the tempo of the music, his hips bucking slightly as he pleasures himself. The melody reaches a crescendo, and so does he, his body convulsing as he comes undone, his cum splattering onto his stomach as the final notes of the song fade away.
