This is a custom clip (no names used): "Training me to stroke like a robot with some background beat (like a metronome) guiding the speed of the stroking. The goal is for me to loop the clip for hours and to stroke robotically and mindlessly even after I cum several times throughout the clip, I have to keep stroking to the beat at all times even if it gets painful."
