Decorum, Miss Granger

[maudite_a_deux]

He watched suspiciously as she gestured with her wand under the linen-covered banquet table. "What are you doing?" he asked irritably.

She leaned toward him so she could whisper in his ear. "If you must know... I've just Banished my knickers."

Her breath on his skin was enough to send a delicious frisson through his every nerve ending, but the huskiness of her voice brought him promptly to attention even as the implication of her words sent him into an uncontrollable coughing fit.

The insufferable minx took the opportunity to thump him enthusiastically on the back. "Oh dear. Is everything all right, Professor?" she asked with barely-concealed glee.

He finally caught his breath with some difficulty. "Quite," he said tersely, favoring her with his most diabolical glare. "Do attempt to maintain at least a modicum of decorum, Miss Granger. You are not among your oafish Gryffindor friends here."

Even as he spoke, he slipped his hand under her skirt via the deep side slit for which he'd criticized her earlier, but which now seemed wonderfully convenient. He smiled inwardly at her sharp intake of breath as his fingers ever-so-lightly grazed over her most sensitive spot. Her mouth formed a shocked, silent 'O'.

"Decorum, Miss Granger," he repeated in his silkiest tones.

"Yes!" she gasped, as his fingers continued their exploration. "Er, yes. Of course, Professor Snape."

But a moment later, her eyelids fluttered closed and her cheeks turned decidedly pink.
