Torture, Tease, and Play with his cock (CBT - Cock & Ball Torture) while you are queening him. Make him lie below you and sit over his face with his head firmly between your legs and his tongue solely dedicated to pleasing you. If he's wearing his chastity device you can play with his balls or bang or slap his caged penis., to remind him he's locked up. If he's not wearing the chastity device, use your hands to apply pressure to on his balls, or squeeze, pull, stretch his cock, in between stroking him lightly and bringing him to close to pleasure, then suddenly stopping just to disappoint him.
The idea is to show you are firmly in charge of his cock and his pleasure while you are getting his pleasure. This is to assert your power, as well as to wickedly and cruelly play with torturing him where he feels it the most.
As his head is buried between your legs, and you are playing torturing his cock talk to him and remind him of his good behavior every time you give him pleasure, while you remind him of his sissyness and his bad behavior as your squeeze, slap or torture his cock.
Do this when you want to assert your female authority and teach him a lesson. Make it tough on him and remind him who's in charge.
The trick is to get him on the edge of orgasm, but to ruin it for him, over and over again, without stopping. See how long he can go.
