Take your pup-play to the next level with the FIDO cocksheath from OXBALLS. FIDO is made from our super-soft, stretchy FLEXtpr so it grips and melds to you like a rubbery second skin. Each sheath comes with a bullet insert that’s designed to fit into the inner chamber for a customizable fit and feel. The built-in COCKSLING at the base keeps FIDO firmly in place, even when you’re pounding a puppy.
