This plumps up my nipples and gives me a level of satisfaction I thought was impossible. I can’t believe the suction power of these and the end result is always plump, luscious nipples that are beyond sensitive. My tits look amazing after using these and the control is very easy to use, the chord at a convenient length. I prefer the sucking feeling to other nipple stimulators, clamps or anything else. Even a nice warm and eager mouth can’t suck my tits like this. I’ve been very impressed in case you can’t tell. If you really enjoy your nipple play and want something high quality then this auto-vac set could just be for you. Pick this up and try it out for yourself.
