VIA Throttle Special Cock Ring - Expert

One way to increase erection power is to squeeze the tip of the penis as with a cock ring, but they have a way of sliding off at the wrong moment and getting lost in embarrassing places. The VIA Throttle solves this problem by wrapping around your ball sac, holding it in place.

This is the "expert" version which comes with two rings, a middle ring with a circumference of of 32 mm and a large ring circumference of 35 mm.

To use, put the middle ring around your penis while flaccid, and bush your balls through the large ring.
