Wow - well, I suppose you're wondering about the, uh, name of this. It's because this ball stretcher device pulls the scrotal sack so tightly that it's supposed to make it hard enough to fuck with. Interesting indeed. *g* The snapped strap is actually shown upside down in the photo and is used as a cock strap while the wide portion snaps around the scrotum, pushing the balls down. Both sizes have three snap positions. The small is 1 1/2" wide and the large is 2 1/2" in width. (Add $3.00 for large size.) Which size is right for you?
