Mistresses Isobel and Rikki order their slave to jerk off, but they want him to do it only by rubbing his dick up against their boots. Of course rubbing his sensitive flesh against the rough boot exteriors and heels makes it almost impossible to cum due to the pain, even when the Mistresses let him use their spit as lube. When the Mistresses actually let him jerk off, the slave cums without permission. The furious Mistresses make sure he cleans up his cum not only from their boots but also from the floor as well.
