I read of, and am now using, a low cost, delightful and simple humiliation and form of ersatz confinement for bitch-boy.
When I have bitch-boy in his little girl or maid’s uniform, an option to confine him
to a given location, (rather than nose pressed to the wall) is to drop a white
paper doily to the floor and instruct him to stand on it until further notice. It
so, so sweet and amusing seeing him standing there (facing me in his shame) and for some reason, he really, really hates it. Wonderful.
