Ruined reward

After weeks of not allowing him to cum, Mistress Lexi decides to reward her slave with a footjob. All seems well as the grateful slave moans in pleasure from Lexi's beautiful feet fucking his throbbing cock. The slave is soon begging for permission to cum, but is denied, as Lexi wants to make him earn his orgasm. But the slave is unable to control his dick and spurts a huge cum load; his cum actually spurts into his own face and even reaches the floor beyond his head! As punishment for his lack of control, Lexi makes the slave eat his own cum, first from off of his face, then off his belly, as Lexi uses her feet to shovel cum into the slave's mouth. Lexi makes sure that he has to clean his cum from the floor as well.
