Sweaty Feet In His Mouth

My feet are particularly sweaty today and have an intense smell. So much the better that I have my slave here, whose mouth I will fuck with my feet! How deep can my foot go into his mouth? He will smell them intensely and slurp them too. He has to suck at my toes and if I am not sated he will be disciplined. The slave has to thank me repeatedly for being permitted to suck and munch my feet. I love this kind of domination!
