Working on a new gag

This is one of the projects that I am working on. I got the idea from watching some fetish videos First the gag is modular, so that you can use a ballgag, O-ring gag, The O-gag with stopper.
The O-gag with stopper forces the sub's mouth open in order to give forced BJ's, drinking, etc.. Then the stopper can be put in for humiliation, as well as breath play since the stopper won't allow you to breath through your mouth. (As always you have to be vert carefull when doing breath play) My safey warning
I am also working on furthur gags such as the gag that lights up when the person gets hit (hehe) as well as the humilator gag with a brush, feather duster, etc..
I also want to make it more of a trainer style with straps that help secure it to the head.
