The Pubic Enemy No 2 is Mystim's clean and transparent cock cage with E-Stim functionality. It allows you to keep an excited penis locked up, so it cannot become erect until the mistress or master comes with the key and lets it out. With the urethral sound and its three conductive surfaces, on the left, right, and underneath the shaft, the captive can be treated to tingling, twitching, or pulsations in exactly the intensity they deserve.
