Description: I have my chastity loser right where i want him, with his useless little dick locked away forever, and his pathetic balls enclosed in my evil shells. his balls are truly screwed. i alternate between teasing his caged cock with my vibrator and tightening the screws of the iron maiden-like contraptions that hold his nuts. how far will i go? will his balls survive?
