That's a nice cage you have! It's one of my favorites too.
So I don't know your limits or likes but I am going to throw some ideas out there and please feel free to use any that you'd like.
1. Spanking, especially OTK. The pain can be chosen according to your limits and it can be humiliating enough to make you remember it every time you are being teased. A good deterrent for the future.
2. Caged teasing/cunnilingus - looks like you had a version of that already
3. Hypnosis like Cal's curse which helps not to orgasm without permission
