Knockers!
Excuse my french, but these Naughty Knockers are just some of the fucking silliest looking things I have ever seen. Designed to be suctioned onto ones nipples, I suppose the next step is to then try with all your will to look sexy. A slight amount of suction seems to be their only sensual benefit, but the horror of the styling far outweighs the fun. At least in my humble opinion. And I am sure you will be as shocked as I was that they are no longer being made.
The good news is, they do actually make fun things for your nipples that are at least little less silly looking.
