A Japanese mature man discovers the joy of solo masturbation, his first experience captured in vivid detail. He starts by teasing his cock, running his hand up and down the shaft, his breath growing ragged. He lubes up a Tenga toy, his eyes locked on the camera as he plunges it onto his hard cock. He pumps his hips, fucking the toy with increasing intensity, his groans filling the room. The pleasure builds, his body tensing as he nears climax. With a final, shuddering thrust, he comes undone, his cum spurting onto the toy and his hand, a satisfied smile playing on his lips.
