If you are referring to Supple Nipps, at the start you should wear them no longer than 15 or 20 minutes, until your nipples adjust to them. Otherwise you may get blisters, which are unpleasant. But once I had broken them in I would sometimes wear them overnight. Within a year or so I had a substantial and permanent increase in size. I would be happy to have my nipples larger, but don’t want them to become too noticeable. What I most want are larger areolas and Supple Nipps don’t help with that.

I've just found something I forgot I had a aldi  ambiano vacuum pump about size of areola suction pump it's for vacuum containers just had it on works great aslong you don't over pump ouch but it did make my areola s bigger .
