I, too, would like to offer some advice and an opinion.

I would question the judgement of anyone that asked me to purposefully undermine my own safety in such a fashion. Nipple clamps, especially the alligator types, cause blood flow to become restricted in the nipples. Extended blood flow loss in any tissue in your body can lead to tissue necrosis (Meaning your nipples could literally rot off), and to a variety of infections, not the least of which is gangrene. I know a lot of people enjoy edge play and like to please their masters, but I have yet to meet anyone who has had the desire to have their breasts amputated in order to prove what a devoted and obedient submissive they are.

Safety first! Consider what it is you are doing to your body before you agree to such things. Be aware of the risks you are taking before you take them. I would certainly recommend that you and your master read up on some techniques before undergoing any furter "play" of that magnitude.

Thanks for reading. Play safely.
