A simple yet sadistic challenge..

Make sure you match your strokes with the tempo of the metronome. Stroke exactly as it tells you to. Grip as tightly as I tell you to. Don't stop. Keep pumping.. If you cum though - then there is a $50 cum tax if you cum without my permission. If you are a good boy and manage to somehow make it to the end, then you will be rewarded with a cum countdown.

Lots of dirty talking, encouraging JOI, muscle worship ..
