The Triad Chamber by Master Series brings the art of domination in three’s. This Chrome Cock Cage features three different sized ‘O’ Rings to ensnare your pet with. The largest ring goes around the cock and balls like a normal cock ring. The middle sized ring goes around the balls providing the wearer with a pressure sensation. The third ring goes around the base of the penis to help you maintain the kind of erection that lasts for extended sessions.
