I have pretty big nipples but I have never thought that there would be enough place for so many - 25 - needles in one nipple. Actually it was not planned, I wanted to do a nipple and clit piercing video but I have stuck with my left nipple for too long - I just could not stop pushing the needles in - so my clit will have to wait for the next piercing session. My nipple got so swollen and sore after this session for several days that I had to put some ice on it and I could not even touch it. 6 days later it is still sensitive.
