Remus stared down at the paperwork on his desk, unbelieving. It was unimaginable that he and one of his students had frotted on his desk over break and nearly come together. Who was he turning into?! He'd denied himself any physical pleasure for years, determined that he didn't deserve it. And now, he'd chose to break his vow of chasticy with a student! An act that could get him sent to prison. What was he thinking?

Then he realised that this wasn't his most immediate problem. They hadn't come together. He was still rock hard, throbbing to be touched, and glancing over, he saw that Hermione's legs were tightly crossed beneath her desk and her hand tapped a frantic rythmn on her thigh. Her hair covered her face, but he could see she was biting her lip, hard. He cursed himself. He had 4 hours of teaching without a break ahead of him, and both he and Hermione had brought themselves to the edge of an orgasm, but not quite over it.

And the sight of her sitting there, aroused and restrained wasn't helping. He realised his hand was pressed against his crotch, and was grinding the heel of his hand down along his cock. He quickly pulled it away, cursing himself. He picked up his pen, and tryed to focus, but his hand drifted again and again and pressed against his cock against his agreement, unable to restrain himself. He was so close, just a few minutes of rubbing and he'd... he was such a monster. He was a teacher, a grown man, rubbing himself through his trousers like a 13 year old boy in the middle of a class full of people. Any of whom might, at any minute come to ask him a question and happen to glance beneath the desk and see...

He stopped rubbing and tried once again to focus. Then Hermione stood up, bringing her parchment towards him. She bent down next to his desk and said, "Sir, I can't seem to find this mentioned in any of the books we have, could you help me please?"
He tried to clear his mind and concentrate on what she said. Her eyes flicked to the paper and back to her face, then he pulled a book towards him and cleared his throat. "Er, yes, this page here..."

He opened it and laid it on his desk. Hermione leaned further towards him and began to read from it, nodding enthusiastically. He tried to keep his eyes from her shirt, which cleared showed the outline of her breasts hanging down, pressed hard against the material. He could see her nipples, hard and clear even through her bra and uniform. She seemed totally focussed on the tome, lips moving as she memorised certain phrases. So he jumped slightly in surprise when her hand slid up his thigh under the table and pressed against his cock.

"Hermione..."

He murmured, and she glanced quickly at him, a half smile playing over her lips. She didn't move her hand, but began rubbing hard and fast. He held his body rigid and stiff, restraining himself from throwing her over the table and taking her right there and then. Her hand rubbed hard through her trousers, the friction driving him mad. He knew if she carried on he would come, hard. He reached out and grabbed her wrist, freezing her movements.

"Thats enough," he said quietly.

Her eyes danced deviously at him, dark with lust, but she stopped, and pulled away. He added in a loud voice, "You can borrow the book until the end of the lesson."

She thanked him and picked up the book and her word, moving back to her desk. He watched her hips sway, and knew he'd never last until the end of the day. He was going to come in his pants, just watching the minx.

Remus dismissed the class five minutes early, and they left quickly, eager for the break they'd been given before their next lesson. Hermione and Remus wasted no time, he bent her hard over the desk and pushed up her robes, pulled her knickers down. He unbuttoned his trousers and released his cock, careful not to touch it as he felt like he'd come on the spot if he did.

Then, quickly pushing into her wet and needful pussy, he cried out. She gasped and arched her back, changing the angle to drive him in further. They didn't last long, a few thrusts and they both came, Remus pinching one of Hermione's nipple hard under her shirt. They'd been waiting on the edge of an orgasm for over an hour, it was no surprise.

The bell went and they sighed, panting. He pulled out of her, satisfied. They sorted out their clothing, and then she left without a backwards glance. No surprise, to her this was just a lustful crush. She just needed his body. He sighed and settled down to prepare for his next class.
