AN: Thanks for reading! As usual, everything familiar is from Rowling's work.
Severus groaned against Hermione's midsection, his fingers still dancing on her damp flesh.
"Minerva has impeccable timing as always," he growled. He straightened up and looked at the girl still kneeling on the desk.
"Get your shoes on," she blinked rapidly in astonishment as he magicked her clothes back on her body.
She scrambled off the desk top and and grabbed the shoes, beginning to fiddle with the laces.
"No time, just slip them on and sit back in your chair at the desk," he said, giving her a slight push. She nodded and sat down, grabbing a book at random and opening it.
Giving a final glance at the room to make sure everything was in order, he unfastened the door knob and poked his head out.
"Yes, Minerva? What could possibly be so urgent that you barge into my classroom uninvited and without knocking?"
Minerva flushed hotly.
"It's about Ardentia Dracula. She's vanished," She snapped.
Astonished, Severus exited the office slowly, attempting to keep as much of the interior hidden as possible.
"What do you mean, vanished? I thought the Aurors were keeping an eye on her until she was out of the country?"
Minerva nodded helplessly, her pale hands spread in an admission of defeat, "They were. They lost track of her in London. She was meant to eventually take the Muggle ferry to France, then return to Romania. Their Ministry already knows to expect her. And now, she's… missing,"
Severus paced, his black robes fluttering about him like a cloud of moths.
"I would say that such a thing is inconceivable, but after the way our Ministry bungled the Dark Lord's return…" he trailed off, staring thoughtfully at a particularly unattractive gargoyle.
"Have they contacted her old associates? Those that are still alive, that is?"
"The only ones that are still around are the Malfoys. They were, of course, contacted immediately. Both Lucius and Narcissa claim she has not contacted them since coming to England at all. They are both firm that they did not know she would be teaching here until Draco's first letter home,"
"And there have been no…Muggle accidents? No unusual mutilations or deaths?"
Minerva shook her head, "None. Either the Minister will have to alert the Muggle Prime Minister, who can set the police on alert, or… we'll merely have to wait until something happens. It's not a very good solution, but at the moment, I'm afraid it's the only one we have. Shacklebolt is furious, though, as you can probably imagine,"
From the office, Hermione coughed. It was a soft noise, but in the great silence of the Potions classroom during the lull of a conversation, it must as well have been the apparition crack of a house elf.
Minerva looked surprised, "Severus, do you have a guest?"
"Less of a guest and more of an assistant. Miss Granger is helping me with research," he curled his lip, "Something at which she is exceptionally practiced,"
The headmistress looked indignant at his dismissive attitude towards her favorite student. He saw her bosom began to swell as she took a deep breath.
"I am grateful for the assistance, Minerva," he said quietly. She cocked her head at him inquisitively, releasing the breath.
"Well," she said finally, "I'm glad to hear it. Now, I was hoping you might check the fortifications in the tunnels leading in and out of Hogwarts. If I recall correctly, you're the one who set them in place,"
He nodded, "Indeed. I'll do that this afternoon, once I've finished with… today's research,"
She smiled approvingly before beginning her retreat from the dungeon, "That sounds like an excellent plan. Oh, and Severus—" She turned her head back towards him, her feet still, "Do try not to be too hard on Miss Granger. I'm sure if you got to know her, you'd find her a most amiable girl,"
He inclined his head, his lips thinned to prevent laughter. If only she knew!
"I'll keep that in mind," his voice was a clear dismissal. McGonagall quickly made her exit from the damp room. Severus returned to his study, leaning casually against the door frame.
"How much of that conversation did you hear?"
She turned to him with a mischievous smile, "All of it. And now that you know me, do you find me 'most amiable'?"
He crossed the room in two quick strides and towered over her, his arms folded in a severe manner.
"I find you most irritating," he said, leaning forward, "invading my dungeon with holes in your shirts to call my attention to your bosom, leaving tangled strands of your hair all over my pillows,"
He was almost nose to nose with her.
"That does sound most annoying," she sighed, looking up at him, "but what do you propose to do about it?"
"Well," he said, straightening up, "I could keep you in here for hours, doing research. I could have my wicked way with you on my desk. With enough imagination, the possibilities are truly endless,"
She was almost breathless with anticipation, "I like the way you think. Particularly with your second idea. Having your wicked way with me on your desk would definitely teach me a lesson, wouldn't it?"
He stifled a laugh at her feigned regret.
"I know if I did that, your escapades would only escalate,"
She nodded seriously, "They really would,"
"Good," Without warning, he swept an arm around her waist, abruptly bringing her to her feet. His lips descended on hers with a fierce kiss, his tongue probing her mouth in an exotic tango. Her hands clutched desperately at his robes, as though she were trying to rip them off with sheer force. He tore his mouth from his and, pointing his wand at the door, locked it and cast the Muffliato charm.
"We won't be interrupted again," he said, his voice ragged. She nodded silently, her hands moving to her own clothes. Again, she threw her clothes in a haphazard pile on the floor. His quickly joined hers.
"No preliminaries," she said against his mouth, "I want you now,"
He was taken aback by the urgency in her voice. Had it been that long since she had experienced sexual gratification? He had thought it only a few days. Nevertheless, he was rarely one to refuse a beautiful naked witch.
Still, a request was a request. He nudged her backwards until her bottom rested at the edge of the desk. He abruptly picked her up and sat her on the hard wood. Without any prompting, her knees parted to let him closer. He looked at her carefully and wordlessly pushed her backwards. She landed on her elbows. With her tousled hair, glazed eyes, and firm, naked body, she was the most tempting sight he thought he'd ever seen.
"No preliminaries?" He gasped, his fingers inching towards her damp center.
She shook her head, sending curls in every direction.
"No!"
He was more than ready, and by the wet slick on her inner thighs, he could tell she was too. Severus positioned himself carefully before thrusting hard. Her body arched on the desk, her fingers clutching frantically for something to hold on to. There was nothing but books in every direction. He continued the movement, his hands grasping her hips firmly. He could see that the indentations of his fingers would leave marks. Smirking to himself, he thought she would probably enjoy the reminder when she saw them.
She was incapable of speech, the only noises possible were a range of guttural moans and soft, high pitched, breathy, shrieks. He paused, his fingers kneading her hips. She opened her eyes, annoyed.
"Why did you stop?"
"Let's try something else," he suggested. Without waiting for her say-so, he withdrew from her. He saw her begin to pout and traced a long finger from her collarbone, over her flat stomach, and down to her throbbing core.
"Trust me," he said softly. She still looked uncertain, but nodded cautiously.
He lifted her up bodily and flipped her, resting her face down on the desk. Her feet, elevated to her toes, were on the floor.
"Let's see how you like this," He said fiercely, thrusting again.
Her response was even louder than before, making him particularly grateful for the silencing spell he had cast on the door. Even if McGonagall returned to nose about, she'd know nothing of their extracurricular activities. He could feel himself coming closer to a climax. Looking at the heaving body before him, he knew she had to be somewhat satisfied—hadn't she exclaimed her pleasure at least four times since they had begun? Still, it was with some small measure of dismay that he withdrew from her, hot white liquid spurting from his member and onto her damp back.
Drained, he fell forward, resting heavily on his hands. She wriggled up, nearly smacking him in the face with her round backside.
"Not bad at all," She panted, glowing. Severus was still winded, and could only manage a brief smile.
"Tea?" She asked cheerfully. He nodded and she bounded from the desk. How could she have so much energy, while he felt as though he had waded through a marsh? It must, he decided, be that had exerted all the energy while she had merely received. He made a mental note for her to be a more active participant in their next session.
She perched, still naked and partially covered with his essence, on the velvet sofa. He almost winced as he saw it, wondering how well semen could be removed from the fabric. He probably had a book on basic household spells, but such a topic could hardly be expected to be found in an ordinary tome.
Still, the prospect of post-coital tea on the couch with a lovely witch was irresistible. With an inward sigh, he joined her.
Later that evening, his arm curled around her in the darkness, he reflected that he had only been able to skim through two books over the course of the entire day. Miss Granger had turned out to be far more demanding than he had expected.
