Creative ways to humiliate someone?

I’m working on a story with a friend and I’m looking for creative ways of humiliating someone. So far our heroine has forced him to wear panties, sent him to bed in lockable panties so he can’t pee, poop or touch himself without permission, used a variety of kitchen utensils to spank him or stick into his butt (safely, nothing sharp or dangerous), is making him wear brightly green colored panties to work, forced him to cum while over lap then clean up the mess (including licking some up) , taken him clothes shopping where she told the salesgirl the panties they picked out were for him, and gone into the sporting goods store where he had to ask a salesgirl which of the ping pong paddles were the best for spanking, then admit his girlfriend was going to use it on him. I’d say our boy is a very sorry boy but he loves her domination. Anything else along these lines come to mind? Thanks!
