The Oppressor chastity device does more than play the role of a typical chastity cage. First, you can have him insert the (cum-thru) urethral plug. You can also apply an anal hook and/or ball clamp. Each of these add-ons are detachable so you can create the setup that you and your partner choose.
To apply the chastity device, use one of the three rings and the penis shaft cage. Each ring has a soft rubber sleeve at the hinge, to avoid pinching and for added comfort. This device secures with a flat head screwdriver. You also have the option to use the Oppressor without the chastity cage; thereby utilizing this device as a locking cock ring with ball clamp or as a ball clamp with anal intruder.
