A slutty after-school demonstration.

"You had wanted to provide a demonstration."

"Demonstration?"

"Yes," the teacher nodded. "It was after we finished passing out the end-of-the-semester reports, and you saw your marks, which were the third-highest in the class. You later told me that you wanted to show me how much of a slut you were beneath that hardworking veneer." He chuckled. "Suffice it to say, I found that a definitively surprising comment out of a young, pretty lady such as yourself..."

Jennifer's jaw dropped, no shortage of surprise striking her that moment as well. There was no way such a thing could've been true. That day she had simply walked out and said bye like everyone else, content to have another swell paper to hang on a wall. But in the same time, he did say he remembered what she promised him, and she was the one who'd forgotten.... what if that was what had happened, and she had it completely slip her mind? She shook her head. But that was so... not like her, and terribly degrading. Of course, she'd promised to bring her dildo to show to him (she normally wasn't a hypersexual person, but she had picked one up earlier out of whim) but that didn't make her an automatic slut. Or a forward one.

Stammering, the girl stood up, pulling her duffel bag up on her shoulder and picking up the dildo with her other hand. "I-I-I'm sorry, um, b-but, Mr. Dinger, I-I think..."

Mr. Dinger's arms folded, face unperturbed. "Come now." Jennifer had already put away the dildo and began rushing towards the exit. "Surely, a healthy young girl like yourself remembers all that?" He shook his head, eyes closed, as Jennifer's taut legs paused, halfway to the door. "I'm supposed to be the amnesiac here. For goodness' sake, I don't even want to think about how old I'm getting," he joked. "Or how much hair I'm losing..."

After a brief moment, Jennifer's back lifted up and down in one breath then turned. A sheepish smile was on the athlete's face. "Oh yeah... of course I remember now." She set down the duffel bag and pulled the dildo back out. "Gosh, I still can't believe I said that. I can be so naughty, can't I?" One hand went to her zipper as she slowly tugged her shorts down. "But it's true," she said, eye darting from one side of the room to the other. "I'm glad you were able to remind me, Mr. Dinger. Because now that we're alone, I could show you the other side of Jennifer Padden. Right..." She patted her pussy suggestively. "...here."

Part of her still couldn't fathom that she was doing this, initiating this. But another part knew that she wanted this, that she, after all, had to provide to her teacher the slutty demonstration she'd promised. It was what she brought the dildo for.

Mr. Dinger watched as a Jennifer that, indeed, he'd never quite seen before, stood in front of him, dildo positioned beneath her vagina. He looked at her grey cotton panties and shook his head. "Is that a thong, young lady?"

"Yep," the girl grinned, as she pulled on her black, thin undergarment with her other hand, and climbed on top of the teacher's desk, spreading her legs. "What, don't like it?"

"Never said that."

"Good. Because you're stuck with it for now..." She pulled her thong to the side as she stared at the older man with a steel-melting look. She teased the entrance to her sacred passage with the dildo, pushing in ever slightly. Mr. Dinger spoke up at that moment.

"Being the secret, repressed horny slut you are, you must be soaking wet right now. So wet you can wash paint off a wall in all that juice. Am I right?" he finished.

The dildo slid in nearly on its own as Jennifer groaned, juices leaking onto the wooden surface below her thighs, her ass pushing against it with each quiet squirm. "Umf, you're not wrong, Mr. Dinger." She began hungrily moving the dildo into her dam-flooded tube, while bringing another hand to massage her dripping clit. It was so productive a pair of mini-rivers had fallen over the edges of the desk to collect at the floor. "I'm so... so wet. Ooh!"

This felt so good. She flicked and rubbed and slid and squirmed, all for her teacher to see and nod approvingly to. It all felt so good. So wrong. So right.

So hot, hot, hot.

Especially for the repressed, horny slut she was! To go through class each day, acting like a decent student, a girl out of the league of any muck in the hallway, while inside all she wanted to do was just rip out her clothes and ask to be their personal dog for the day, or suck a cock for some quick cash; it was maddening, bottling it all in. Which is probably why she presented this opportunity in the first place.

Yes.

Yes, she hoped Mr. Dinger would appreciate this demonstration as much as she did. And her vagina. As she looked up at her teacher, and bit her lip while she adjusted her legs to give him an even better view, it seemed like he certainly was.
