I guess about 20mm in length and maybe 11mm in diameter, beautiful tits too. Love to see her wearing a lacy longline bra with peepholes to let those fancy nipples poke out.
It isn't a fake, silly. Here is the video of me taking the nipple suction cups off. https://xhamster.com/videos/redhead-little-tits-and-huge-nipples-in-suction-11444348. It's just an hour or so of nipple suction with size 5XL Supplenips. My nips are already large but when I put those huge silicon suckers on them for a while they get that big. Who would go through so much trouble to fake something like that?
If you have a look on her right nipple you can see the edge of the adhasive foil and also you see a different colour between the Nipple peak and the Aerola. That is the fake!
