She's staying. For extra credit.

Margot says nothing as her panting slows, still reeling from the beastly pounding you gave her. A string of your cum dribbles out of her cunt, and finally she pushes herself up, albeit weakly. She turns to face you, with surprisingly misty eyes. She purrs softly and sways her hips, her hands rubbing up and down your chest.

"Um, alright, Miss Childers," you say, taking her wrists in your hands, "It's time for you to go." She ignores you, moving one of her hands to make it so yours rubbed against her cheek. She hums huskily as she leans her cheek against your hand, but you let go in response. "Really, Margot. You have to get cleaned up before someone sees you." Her only response was giving you a sultry grin before turning her back on you, reaching back to wrap her arms around your neck, swaying and grinding her body against you.

"And if someone sees us, they'll see I'm your little Prairie Vole..." she growls sexually. Being that you're a biology teacher, you remembered that Prairie Voles are monogamous. What the hell is she trying to say?

Your mind starts to race with anxiety. What if she told someone what you did to her? Can you trust any of these horny Pink Rose girls to keep their mouths shut? Before your train of thought goes much further, she gives you a sultry look over her shoulder.

"Thanks for tutoring me... But I want to do more than pass. I want to graduate with honors...and I'll need a lot of tutoring....Lots more."

Christ, the little bitch was insatiable, you think. You don't know that you can continue to fuck her, or at least summon the energy for a second round. She reaches behind her and squeezes your flaccid cock with practised skill, and you have little doubt that she could have you hard again in moments.

"You wouldn't want your tutor to be dismissed, would you?" you asked. That was when she stopped.

"No!" she assures you, turning and hugging you tightly after releasing your dick. "You can't leave. Not yet."
