The Slinger Ball Stretcher by Sport Fucker is both a ball stretcher and a cock ring, and is the ideal hybrid of the two. You can use The Slinger either at the base of your cock and balls, or at the base of your shaft, or as a ball stretcher to deliver super effective erection enhancement and intensified pleasure. It has a large footprint without a lot of mass - which means more stretch and flexibility for the well endowed male. Made of super stretchy TRP rubber, when used as a ball stretcher it is designed to fit guys with large balls. This is the red version.
