Mistress Xena steps out to use the restroom. What does She come back to? Her useless employee jerking off.
Mistress is furious that this pathetic 'jerk off' masturbates at work. She notices cum on his stomach, as well.
"What the fuck! You seriously cannot control yourself."

So Mistress humiliates him before he is kicked out of the office, for good.

She feeds him his own cum, spits in his mouth, slaps his face, verbally humiliates the loser.

"Ok. Now you're fired. Get the fuck out of here!"
