I admit, the pump was actually not advertised as a nipple pump, but intended for penises or glans - but since the small suction cups fail on my large nipples and piercings, I simply misused them;) I love it when you plays and sucks with my nipples, so why not try a toy for it? And I am pleasantly surprised how good it feels;) In the video you can see my reaction to the first test game with the pump and you can also watch a little close-up as my nipples are sucked in by the pump.
