ELONG nip-suckers workand look so cool. They are slightly curved but not tapered--these will suck any size nip and are deep enough and big enough to fit small to medium piercings. These suckers stay on, the base flares out for more contact with skin--even furry chests. What gives these powerful suction are the four springy rings that make the nipple-tube pull open without collapsing like old snakebite suckers--we made the walls thinner to allow for more pump, largersuckednips. To apply, simply wet the bottom of each sucker (we recommend spit but hey, we don't judge), squeeze out the air, stick them on your tits and enjoy the nasty nursing sensation.
