Trained to cum by smelling sweaty feet

Description: He is a compulsive masturbator - he used to masturbate several times per day and another several times at evening/night , every single day! lucky him, i will take care of his ,,obsession,, and i will make him a better slave! i locked his cock into a chastity cage- he is now locked from 21 days ! today i will give him a release permission but in my very specific terms: he can't wank, he can't touch his cock at all ! if he wants a release, he must smell my sweaty feet and cum under my feet ! this is the proper way for a foot-slave to cum: only by smelling his owner feet and only under his owner feet! i open his chastity cage, i place one foot over his nose and another over his cock! he gets hard instantly! i begin ordering him to inhale the strong smell of my foot while i tease his cock with the other foot! at one point, i get a brilliant idea! the person behind camera, in my case is not a camera-man, is a camera-woman ! is my best friend, nicole, she is filming for me all time and while filming this clip, i thought : if she have a sweaty feet too, will be even better for my slave's training! so, i invite her to gets her bare-feet over his nose as well, while i hold the camera and record nicole's sweaty feet and my foot on his face but also my other foot on his hard cock! it takes just a minute for this pathetic creature to cum and now, i give back camera to nicole, so she can record how he eats his own semen from my sweaty feet! i want to train him to become so weak for sweaty feet ! so weak, that, if he enters in a space where smell like sweaty feet, he would get instantly and erection! i know i will be successful - just need some more time! now he is back in his chastity cage again and guess what he is waiting for? - another occasion to smell sweaty feet and to cum by footjobs!
