Making my slave feel pain is nice but humiliating him at the same time is even better and gives me the extra kick. I have got him prepared, nicely strapped down and gagged. I have put on some bright girly yelllow latex stockings and some equally yellow mules with pointy sharp heels. Immediately I start to work on his soft male flesh. I drill my heels deeply into his balls and step on his hard dick. With some lube my and my skilled rubber feet he has no chance but to come humiliatingly all over my sexy yellow rubber feet.
