Got these along with adjustable nipple clamps and thought they were way too tight, but... got them out again the other day and oooohhhh my! Started out with them higher up on my aureolas and inched them down closer... and closer to the tips. Exquisite! I think that next I'm going to put some weights on them and keep them on while I do my weight lifting routine. With my large breasts and the weights on the clamps swinging and pulling, I strongly suspect that one finger in my hunnypot will send me right over the edge. If you like a bit of painful pleasure and your nipples are a major erogenous zone like mine, you've got to try these!
