Facesitting Slave Femdom!

I made my slave wear a chastity cage, because I just love teasing & denying him. Today I will give him lots of facesitting, to make his dick suffer in the cage. First I sit on his face with my panties on, but soon enough I take them off and putt my bare butt cheeks on his face. This will be lots of fun! At least for me... Of course I let my slave know, what the purpose of this entire training is. His sexual release is unimportant. He should reimain caged & horny, to become a more obedient slave for me. All that matters, is that I have fun! My sub should strive to become a better object of pleasure for me!
