In a desperate bid to maintain rhythm, this frustrated masturbator sets his metronome to an unyielding pace. His fist flies up and down his throbbing cock, matching the relentless beat. Precum lubricates his frenzied strokes, the metronome's ticking growing louder, more insistent. As the beat reaches its peak, so does his pleasure, resulting in a explosive cumshot that leaves his hand and the camera coated in his sticky, white essence.
