She leaves

To your surprise she's only a few minutes in your bathroom, emerging looking fresh and unfucked. She gives you a grin, then sways towards you, her hands creeping up your chest as she turns her head up nibbling your chin.

"My wicked wicked biology teacher," she purrs. "Teaching me so much."

You stroke her hair, looking at her thoughtfully, still unsure of how much of what this girl says is sincere and how much is artifice. Certainly she is a highly sexual little animal, enjoying being fucked, and clearly excited by bondage; but you sense a deeper intelligence beneath her wanton libido.

"You're a bad little bitch," you tell her, seeing her eyes flicker with sensual humour.

"A nasty little rich bitch," she agrees with a sultry purr. "A dirty girl who's entranced by her wicked biology teacher. The wicked man who uses her so hard when she's helpless. Forcing her to orgasms when she can't stop him."

"Orgasms she loves," you say. "Orgasms unlike any she's ever had."

"Mmmmmm, yessss. So very good. My poor little holes, so ravished and stretched. And so happy and content. You're a very bad man Mr. Carter. My wicked, wicked biology teacher."

"You need to go," you tell her, holding her chin between your thumb and forefinger.

"Yes. I do. But you're going to use me again," she says with a firm smile. "Bind me and use me and make me scream. I do love it so you wicked man." She gives you a salacious teasing smile and flounces away, skipping down the stairs to you front door. She stops and looks back at you, suddenly lifting her skirt to flash you her bare ass, before opening the door and stepping outside.

Shaking your head, you look into your bedroom, seeing her panties in a ball on your bed.
