Get ready to have your nipples sucked with these Sport Fucker Silicone Nipple Suckers. You will love the simple way these tit tuggers work - with just a push of the middle of the cylinder your tits get pulled. Made of silicone, the Sport Fucker Suckers delivers a really good vacuum that will definitely swell your nips. These are the heftiest and strongest flexible suckers around so they are going to stay put - even during pounding action. This 39mm size is good for pro tit pigs as they are big enough to work with pierced nipples and deliver twice the suck.
