*****

Severus sighed and squinted at the jar in front of him. 'Manticore's spleen', it read. There was no sound in the dungeons of Hogwarts besides the crackling of his office fire and the soft clink of the flasks as Snape shifted them around. He glanced at the clock: 11:30 p.m. He should turn in soon, even if he had not finished the inventory.

There was a sound.

Someone had released the wards to his office and opened the door. He turned to catch sight of long pale fingers with black nail varnish and knew exactly who it was. Why is Aurora coming to see me in the middle of the night? But, no, she did not expect him to be in his office; she had undone the wards instead of knocking.

So what does she want? And how did she manage to banish my wards?

Snape hesitated for a fraction of a second, but curiosity won out. He waved his wand to snuff the lamps in his storage room, then cast a Disillusionment over himself. If she did not look for him, she would not see him.

Aurora slipped into his office and surveyed the room. There was a fire burning in the hearth, but otherwise she saw no sign of life. She smiled. The girl sauntered over to his desk and trailed a hand over its top. Her attitude, normally so insolent, was oddly reverent as she performed this action.

How did she bypass Filch? Severus wondered, but he knew the answer as sure as he knew Aurora's soft beauty in the semi-dark. Argus Filch had known the Sinistras since Aurora was a small child. Despite his dour disposition and normally dim view of young people, Filch had doted on the fair-haired daughter of the Professors Sinistra, as had the entire staff of Hogwarts. Despite his threats to treat Aurora like any other student, Filch would likely give her a pass if she smiled winningly and produced some innocent reason for wandering the castle after bedtime.

Aurora walked around the desk to sit in Snape's own chair. Her back was now turned toward the man himself. Her short-cropped hair glowed like a halo in the firelight. She slumped back in the chair and sighed, gripping the armrests. Then the girl kicked off her trainers to reveal bare feet.

Severus' brow furrowed. What is she doing?

His concern was soon resolved in a terrifyingly glorious way when Aurora rose and slid her robes over her head to reveal a nightdress. The thin garment soon followed her robes onto the floor. She now stood where he himself had stood so many times. But he had never stood there in complete undress.

He opened his mouth to speak, but no sound came out. Instead, his eyes were drawn to the youthful lines of her back and bottom. His gaze devoured the long, graceful expanse of pale flesh. When she turned toward him, the curve of her backside as it met her thigh stopped his heart for just a moment. Aurora settled herself on the edge of his desk, cupping her own breasts thoughtfully.

Snape took an unintentional step back, then silently renewed his Disillusionment. If she looked up, into the doorway of the storage room...

But she did not. Her eyes were focused on his desk chair. A dreamy smile played over her lips. It was still cool in the dungeons, even in May, and gooseflesh puckered her skin. She reached down into the pile her robes had made on the floor and removed a small flask. One thumb toyed idly with her nipple as she took a healthy draught.

She's drunk! Snape realized. He willed himself to close his eyes, to shut out this secret, shameful moment of a girl he had known when she was a child.

At that moment, Aurora let her fingers trail down her smooth belly toward the patch of curls where her thighs met. She put down the flask and propped one foot on the seat of his desk chair. She scooted her hips forward on the desk, allowing her thighs to fall apart.

Stop this, Severus, before it goes any further! It's Aurora! Stop it now....

The girl bit her lower lip and slid one finger between her legs. She tossed her head back, eyes slipping shut. Another finger joined the first. Aurora parted her legs further, so that now, in the firelight, Snape could see her dripping pink folds. He watched, fascinated, as she spread her nether lips. He could clearly see her stroking the engorged nub of her clitoris. Snape swallowed, his mouth suddenly dry. He became aware that his erection was painfully hard. He rubbed the swollen member distractedly through his trousers as he watched Aurora pleasuring herself.

A laugh bubbled up in her throat, and she addressed the chair, "Are you enjoying this?" Her voice was huskier than usual. She slid two fingers into her passage. "Fuck," she hissed with pleasant surprise. "Bet you wish that was your cock, don't you?"

Snape did. He squeezed his erection, willing himself to remain calm.

Aurora's fingers busied themselves inside her passage and at her clit. She began to moan, and her breath was ragged. He could see the long muscles along the inside of her thighs clenching tightly. Suddenly her movements became frenzied.

"Fuck, I'm gonna come. Oh, Severus, fuck!"

Snape groaned aloud when she called his name, his erection harder than he could ever remember it being in his life. His lips formed her name. Aurora was unaware of his plight, however, as she gasped and shuddered, ecstasy washing over her.

When it seemed that she had wrung the last drop of pleasure from her tender, sopping flesh, she rose on shaky legs and took another swig from her flask. She stood for a moment, breathing deeply. Then, with trembling hands, she dressed, grabbed the flask, and stumbled out the door. Snape sensed her replacing the wards.

As soon as he knew she was gone, he collapsed to the floor and tore open his trousers. Leaning his forehead against the sharp edge of the countertop, he stroked himself furiously. Snape remembered the sight of her sex, imagined himself thrusting viciously into her tight, dripping passage. Groaning, he climaxed without warning and spurted his release on the cold stone floor.
