Speed up the pace, slave.
After 6 months, you didn't need the belt. You had such self-control that you wouldn't so much as look at your cock without My permission. Not only because you knew what would happen if you did--but because on a very basic psychological level, you had been conditioned not to touch your cock.
In a way, it was as if you were wearing the belt, because you couldn't touch that cock even if you tried. Your brain had been so reprogrammed by my conditioning that it did not know HOW to make your hand touch your cock without me asking it to.
And that was when I knew I could have some fun. For the next 2 months, I would only let you stroke to porn of certain fetishes. Each one was different, but all of them were ones you listed as limits before coming in with me. Pretty soon, you were begging me to do those things to you.
