Make her service the prof

"Susie, shut it."

The tight-bodied Asian girl closes her pouty mouth mid-exclamation.

"Close the door, come here, and obey," you say, still groping your prof's tits.

Susie does just that. You tell her to strip to her underthings, and she reveals a black bra and panties as she stands bewildered in front of you watching you fondle Porter's tits and ass.

You figure the poor cum-splattered professor deserves a little relief now. You make Susie kneel on the floor just at the right height to bury her tongue in Professor Porter's pussy.

As Porter sits on her wild Asian student's face, she soon starts moaning. Evidently Susie has quite a skill at eating snatch.

You lean over and whisper to Susie. "You'll come by Professor Porter's office hours every day and serve her pussy any way she likes."

Porter chooses this moment to scream in ecstasy. You pick up a permanent marker and slip it into her fingers. "Susie here's a regular A student at eating your snatch. You'll make her eat you out every day. Your favourite thing will be to get fucked by all your male students and then have Susie clean out your pussy with her tongue. Oh, and you'll write an A on her bare skin every time she makes you come."

Porter scribbled an A on Susie right shoulder as she rode her face and then stiffened, screaming in ecstasy again. She drew another A, still riding Susie's skilled tongue.

Delighted in the wild Asian girl's degradation, you start jerking off in her hair as your professor rides her face.
