Genital bondage simply can't get any better than this! A small, moveable hook-shaped frame attaches to the glans ring, which is worn tightly around your cock's head. An 8mm steel sphere attaches to the other end of the frame and is inserted into the urethra.
Your cock's head becomes firm and, just like during an orgasm, will tremble!
Tip: Especially interesting during anal action! An incredible feeling for both top and bottom!
