If you don't need it, lock away your partner's penis. This beautiful and unique chastity device encases the penis in snug stainless steel, leaving a series of holes open for urination and airflow. Three different sizes of O-rings are included to find a comfortable or uncomfortable fit, depending on what your slave deserves. However, the special feature of this device is the internal locking mechanism. Insert the key into the brass keyhole and turn it to align the lock. The lock can then be inserted into the hinge. With another press of a button, your slave recognizes your complete control.
