As mentioned on other sites, this can be tricky to get on. The trick is to turn it inside out, and then put your balls in one at a time. It can be easier if wearing a latex cock and ball sheath already!
Once on, it creates a pleasant sensation of tightness (depending on size/fullness of balls!). and looks great. Very nice to orgasm in.
All in all, I think you will enjoy this if you are a rubber fetishist and/or bondage lover.
