This is the standard Mister B Leather Double Cockstrap, adjustable with snap studs. The long strap is meant to go behind your balls, gripping both your dick and balls together. The second shorter strap of this Mister B Double Cockstrap is mainly intended to use as penis ring, but can also be used alternatively around your balls.
This leather cockstrap is lined on the inside for extra comfort. Because the undersides of the bottom snap studs are covered and stitched in the soft leather lining, no metal parts touch your sensitive skin or can cause irritation.
Depending on what setting you put it, the resulting inner diameter of this cockstrap varies between approximately 40 and 50 mm, ensuring a nice snug fit around your dick.
Having this cockstrap around your dick and balls will lead to longer and harder erections which you (and / or your partner) will enjoy.
Also available in another version with a wider secondary strap, or in a titillating version with pin prick.
