That day, Remus set all his classes essays to write, and sat at his desk staring blankly at work he was supposed to be marking. The students talked quietly amongst themselves, a few even seemed worried about their usually bright and cheery teacher, who gave interesting lessons, not essays. When it was the seventh year class, he set the work without looking once in Hermione's direction. He could feel her gaze burning into him for the whole hour, but he kept his head down. When the bell went he turned and quickly entered his office at the back of the classroom.
Minutes later, he heard a knock at his door, and it opened unasked. It was her. He could see that the rest of the class were just leaving. She stepped into the room, blushing red but determined, closing the door behind her.
"Sir, I still need your help with my problem. You see, it may be just a crush," she said the word distastefully, and continued in a whisper "but my body is still aching for you. All night I writhe and dream about you, and wake up wet and throbbing. It's stopping me sleeping, and as a result my schoolwork is slipping. Please. I don't know how else to stop it. I have tried..touching myself. Often. But it makes no difference. When I am around you I am still soaking wet and desperate. Please." She was standing in front of his desk, staring into his eyes, "Please. Touch me."
He couldn't move, he was so shocked at her words. This wasn't the Hermione he had known for years. For her to admit this to him in such a way, she must have been planning it for months and could see no other solution. How had he not noticed he was having this effect on her? It greatly surprised him. He'd thought her words yesterday had been the innocent attempts at seduction of a schoolgirl, hoping for a sweet kiss, but here was a woman, begging to be touched! How had he overlooked all she had gone through at Harry's side, facing Voldemort himself, and how it had changed her? She was a different person, much more confident and determined to waste no time in getting what she wanted.
While he thought all this, he realised that while his mind was uncertain and indecisive about the sentiments Hermione was expressing, his body had made up it's mind and was responding whole heartedly. His cock strained against his robes, the friction delightful but constricting. He half rose, and sat again.
"Hermione..." he whispered. She stepped around his desk, and faced him up close. He quickly stood up, feeling vunerable below her gaze. Suddenly, she pressed her body against him, taking control in a manner at odds with her schoolgirl attire. On tiptoes, she lifted her lips towards his ear.
"Please," she breathed into it, "I need you to teach me.." She pulled his earlobe into her mouth and sucked it, nipping gently. Remus was frozen once again by her actions, breathing raggedly. Without giving time to think about his actions, he let out air in a gasp and turned his head, grasping hers in his hands and gazing into her eyes. He bent down and quickly pressed his lips onto he pulled back, stunned, and closed his eyes. Hermione was still, on tiptoes, leaning towards him, one hand on his shoulder. He opened his eyes after a few seconds, gaze hard, and, ignoring her expression (lips parted, breathing rapid, eyes hooded gazing at him, giving herself to him) he said, "I apologize. That was inapp-"
Before he could finish, she had reached up and cupped the back of his neck, pulling his head down and pressing her open mouth over his. He kept his closed, but didn't pull away, unable to. She ran her tongue over his lips and pulled his bottom one into her mouth, sucking hard. He let out a long, shuddering groan and opened his mouth, letting her explore it with her tongue. As he relaxed, they both fell from the precarious position, until Hermione was pressed against the desk edge and he was bent over her, hands on the desk at either side of her to support himself.
After a long minute, he pulled away, gasping. "This won't work."
She looked half unable to think with desire, but frowned, moaning, "No! I don't care if you're my-" He interrupted, saying, "I meant, this," gesturing to their awkward position. His back was starting to ache from bending so far over and he had no hands free to touch her. He moved his hands from the desk over her and cupped her bottom, lifting her up onto the desk. Ignoring how close his fingers were to her center he slid between her legs. She automatically twisted her legs around his thighs, pulling them as close together as possible.
"Much better," she sighed, looking into his eyes which were now level with hers. He kissed her again, exploring her open mouth with pleasure. She let him take control, moaning hands ran over his shoulders, his cupping her buttocks firmly. He used this leverage to pull her even closer, and groaned into her mouth when his hard cock came into contact with her crotch. She moved her hips in a roll, rubbing herself against him through layers of clothing.
His lips left her mouth and moved along her neck, nipping her collarbone and sucking at the top of a breast that was reachable in her shirt. Disgruntled, he reached up and unbuttoned the top buttons, freeing her breasts and pushing her bra out of the way. Their hips were moving in time against each other eagerly, desperately.
He took her nipple in his mouth and sucked hard, then bit gently. She gasped and moaned into his hair, hands slipping around his neck, and pressing him closer.
Then the bell went for the end of break. They froze, and with shaking hands he fixed her bra and did up her shirt. They were still pressed against each other, and neither moved. He kissed her lips lightly and went to move away, but she let out a purr of disagreement and moved her hands to his arse, squeezing and pulling him hard back against her.
He frantically bucked, desperate for friction, and for a few minutes they stared into each others eyes, gyrating.
Then the first of the students came back into the classroom, talking noisily. Hermione pushed him away, and pressed down her hair, not looking at him. She hopped down from his desk and left his office, calling back to him, "Thank you for your help Professor Lupin, that makes much more sense," and went to sit down next to Ron Weasley, who teased her for staying over break to carry on working.
Remus stared through his open office door at her, mind unfocused and still rock hard, then shook himself. He pulled his robes around him to hide any conspicuous bulges and made his way into the classroom, telling the class to carry on with their essays, then sat down at his desk and stared unbelieving at its surface. He couldn't believe what had just happened.
