Mystim penis cage with electrostimulation function. It allows you to keep a disobedient penis locked under lock and key, so that it cannot harden until the lover comes with the key and lets it out.

With the urethral sound and its 3 conductive surfaces, left, right, and below the axis of the penis, the wearer can be treated as desired with tingling, contractions, or pulses at the exact intensity he deserves.
