Naked, tied, locked and ruined

Description: Custom request: my slave would be naked, hands tied in his back. head down. balls up. one foot in his mouth to keep him silenced and i would play with his dick and balls. at the beginning of the video his dick is locked in the cage and he is gagged. i arrive and my feet are at his head level. i take off my shoe and put my foot on his face/nose. i grab his balls and play with them and give some slaps too. my slave moans through the gag, but i don't care. i take his gag off and shove one foot deep in it. i fuck a bit his mouth. then i keep it deep and keep on playing with his balls. he is at my mercy. then i take out the chastity cage and give him a handjob. i make my own game "stop and go" and i give some slaps on the balls when he is too excited and my feet still inside his mouth until he cums and i ruined his orgasm with slaps and etc.
