Chastity Sub left on Homemade Auto Edging Machine made to cum in his cage

I rigged a devious auto-edging machine with a wand vibrator attached to a piston, aimed right at my sub’s locked cock. He’s mummified to a board and can’t move. The machine relentlessly vibrates his chastity cage, edging him mechanically. After a while, it makes him cum inside his cage – a painful, unsatisfying orgasm. His cum leaks through the cage bars as the machine keeps going, milking him dry. This was him being made to orgasm in chastity, courtesy of my DIY fuck machine innovation.
