Well, the first time I got them done, it hurt. Like hell.
The second time hurt way less than the first, which is surprising, since it was deeper in.
I'm assuming, though, that it's because my actual nipples are wayyy more sensitive than the areolas, which is technically where the second ones are.

But I'm satisfied with the results. I have a spike on the bottom of the vertical bar, with a ball on the top part, and a horizontal horseshoe with spikes on either side. It makes it look like I have an upside down pitchfork on each n****e. ^_^
