"Now, come suck my cock."

You ignore her unhappiness. "Now, come here and start sucking. 'It's cruel not to let me cum.'"
She looks up at you, shocked by your mocking words.
"Come on, now, that's a good girl."
She picks herself up and sighs. She has to do it. She can't disobey her owner.
"Undress me with your teeth," you say, and stand up.
She comes up to her knees and begins using her incredibly nimble mouth to remove your pants and underwear. Your anticipation builds and as she pulls down your underwear your hard cock springs up from the waistband and slaps her in the eye.
