Oxballs Gear Ass Lock
An asslock is an anal plug attached to a cock ring-- Oxballs makes these in a fantastic soft, platinum-cured silicone. The Gear is 1.875" at its widest diameter, with a 1.75" diameter cock ring. The distance of the connector between the ring and plug is 3". Lock yourself up (in a good way) today.
100% silicone means you can clean up with soap and water, the top rack of your dishwasher, or you can even boil in water to sterilize.
