Slave to My feet after the treadmill (Mistress POV)

Description: The biggest motivation to train on the treadmill is knowing that afterwards i will have a slave who will take care of my smelly and sweaty feet, make him smell my shoes, socks and bare feet. having him on his knees tied in chains, in absolute bondage, having me lick them, and all while i whip him to make him understand that he will never be worthy of being my submissive slave, that he must always do more for his one goddess and absolute mistress
