Mistress punches him, kicks him and generally him, which after all that's what he is there for. The slave on all fours licking Mistresses poor aching sweaty feet, a job that he enjoys so well, Mistress decides to let him suck on something else, yes, her strap-on. As he does so well she decides to reward him with a treatment from the Super Mk II De-Spunking machine and afterwards a good milking.
