The Cock Cage is subtitled The Triple Helix Enhancer. Three black catheter tubing rings of gradually increasing size are joined in such a manner that each is connected to the other two. The connecting device is a small black rubber band. Each ring snaps apart and re-closes with a peg that fits into the hollow interior. If the user finds any of the rings too large, the ring can be cut to size. If the user finds the rings too tight, all the more fun. First I fastened the largest ring around my cock and balls, which immediately began to swell. Then I wrapped the medium ring around my scrotum and hurried to fasten the tightest ring around the shaft of my penis, being extremely careful not to pinch any skin or catch any hairs. Now that my cock is engorged, with the veins bulging...I gotta go.
