Fido Pup-Knot sheath for men comes complete with a thick knob right in the middle and anchors to your nuts with a firm, stretchy band. Pump your dirty mutt`s brown pucker with this ultimate pup backdoor stuffer by Oxballs! For some serious grip on your package while you bang his hungry hole, burp out any excess air by tightly squeezing the length of Fido down to the base. Fido Pup-Knot feels fuckin` hot swinging between your legs when you`re down on all fours - or while you`re sinkin` furry balls deep up some bitch in heat. Lubricate well with your favorite water-based lube to guide the sleeve and band into place, and clean up in a snap before and after puppy fun with antibacterial soap and a warm water rinse.
