These little brutes suck your nipples tight through hours of rough play. Simply lick ’em or apply a tiny bit of lube, press them on your tits, and feel your nips gradually SWELL! The pressure is not too hard…just right for a nice suck, without the pain of old-school nip gear. If you have particularly hairy nips, lube up your tits with chapstick first to ensure suction. Pro tip: press the top dome to push the air out of them first (they should make a popping sound) before pressing them on.
