"Close the door, Potter," said Snape, as the boy entered his office. Snape gestured to an uncomfortable-looking chair and Harry made his way over, focusing more on the assortment of stoppered flasks on the desk before him than the visage of the potions master himself.

"For today's detention, Potter, you will be doing me a great favour by sampling this experimental series of potions-"

Harry bolted upright in his seat. "Experimental? Surely, sir, the headmaster wouldn't let you-"

"Sit DOWN, Potter," Snape growled. "These are all simply reformulations of existing formulas, and none will do you any harm in any way. If anything does go amiss, there are few better people to assist you than I."

Harry slowly sank back down in defeat, looking at his feet. "Yes, sir."

Snape nodded. "Let's get this over with, then." He passed Harry a small vial full of a clear liquid that burned his throat with an intense cinnamon sensation, leaving him gasping for air. Harry opened his mouth to protest to find that his throat had been numbed and he was rendered incapable of speaking.

Snape chuckled darkly, his eyes meeting Harry's own. "And that will curtail any more of your inanity, Potter. Potion of Silencing. It's very old, but very effective. My take on a classic, you might say." He continued to look into Harry's eyes long enough to make Harry uncomfortable, focusing on the array of flasks on the desk again.

"I see her every time I look into your eyes, Potter," Snape said in a soft tone of voice, one which Harry was not used to hearing from him. "You wouldn't think so, but I'd known her for a very long time- from before we'd even gone to Hogwarts together." He opened a small wooden box on the desk, retrieving a small silvery locket on a short chain. "She gave me this before we'd started her first year." He dangled the locket from a pair of fingers, letting Harry get a look at it.

Harry swallowed softly as Snape lowered the locket. He could not conceive why the potions master was telling him this, nor could he discern what the locket had to do with anything, even as he watched it sway through the collection of glassware that separated the two of them.

"Enough of that," Snape said, seeming to catch his train of thought as he lowered the locket back into its box. "Here's the second, Potter. It's something you should be familiar with." Snape passed Harry a flagon of something thick and mud-like. It was a deep crimson in colour, and sparkled in the light. "Bottoms up, now." Harry stared hatefully at Snape for a moment before tilting the flagon and draining its contents in a single gulp.

"Polyjuice, Potter, as you undoubtedly guessed. You and your little clique have made enough of it over the years." Harry looked at the back of his hand as the skin there began to crawl, his features melting and reshaping as his robes started to grow loose on him.

"It's a new formulation of Polyjuice, if you've wondered, Potter," Snape murmured. "Much easier to make than the traditional recipe; takes weeks instead of months to brew." A long finger slipped over Harry's curiously soft cheek as he struggled, rapidly getting tangled up in his oversized robes, his shoes sliding from newly tiny feet.

A wicked grin came across the potion master's features as he slid his fingers appraisingly through Harry's newly long tresses, his eyes meeting Harry's again. "Just one more, Potter," Snape said as he pulled on a pair of dragonskin gloves. He reached for a large rounded crystal flask filled with a shimmering, musky oil and pulled the cork stopper. "This one is effective for a short time only after coming in contact with the air, Potter. Try not to be too alarmed."

Harry screamed soundlessly as Snape upended the contents of that flask over his head, drenching the folds of the over-sized robe and his struggling body. Something in that oil made him catch his breath. His skin burned where the fabric touched it, a growing heat welling up in his belly as well. He gasped noiselessly as he pulled his robes over his head, flushing with embarrassment at exposing himself and that fluttering deep in the pit of her belly. He blinked, catching his reflection in a mirrored flask. He had become a little girl with long auburn hair, her pale, naked skin glistening with that potion-spiked oil. Her hands clenched for a moment, biting at a lip as her legs parted, tiny fingers sliding over a bare inner thigh, trailing over the new, soft, dewy folds between her legs.

One thing struck her as very peculiar; the eyes that met her own through that mirrored reflection hadn't changed.

"Curious, Potter?" asked Snape, lowering his gaze to meet Harry's, seeming to relish the confusion in the former boy's eyes. "Your dear mother gave me a gift, right before we started our first year here." Snaps lifted the silver locket so Harry might get a better look at it. "It's not real silver, of course, bought from a toy store with the pittance of an allowance her horrid family gave her."

Harry's only reply was a soundless, impassioned moan as that oil soaked into her skin, inflaming her senses. She looked at the shining bauble through lust-clouded eyes, trying to keep her attention focused on the locket, the flickering torches, the sound of Snape's voice; anything but that needful ache between her thighs.

"She gave me all she could with this locket, Potter. Simply a girl's soft confession of love and a single lock of that beautiful auburn hair." He looked to Harry even as she slid to her knees on the dungeon's floor, her teeth clenched as need overwhelmed her. She sank to her knees, fingers sinking into her swollen, needful sex. Snape shook his head, his expression one of distaste. "I thought it would be nice to see her face again, but you cannot even maintain enough composure to keep your clothing on." The potions master reached for his wand, tapping Harry's throat. "I do believe your detention is over, Potter. Put your robes on, and you can go."

Harry gasped aloud, realizing that her voice had returned. She flushed bright red as she looked to the oil-soaked robes, and then up to Snape. "Professor-" She paused, surprised at the higher timbre of her voice. "What about the-"

Snape waved a hand dismissively. "Polyjuice wears off in an hour, as you know, Potter. The oil should last just about as long." He stepped back behind his desk, looking at the girl before him. "You've been though quite a bit, Potter, even escaped from the Killing Curse itself. Surely you won't be phased by a little thing like this."

Harry's skin was flushed bright red as she rose on shaky legs, slipping the hand she'd been unconsiously masturbating with behind her back in a lame attempt to hide her sticky fingers from Snape. "Professor," she said softly, her free hand slipping over her belly, feeling the fluttering within. "I... I need..."

The potions master rounded his desk, his fingers sliding again through Harry's oil-slickened hair, a fingertip tracing down along her spine. "You need, do you?" he replied. "And just what is it that you need, girl?"

Harry whimpered as that touch caused a shudder to pass through her body, toes curling beneath the stone underfoot. "Yes," she whispered. "Don't... don't stop." She arched back to Snape's fingertips as they slid lower, along the cleft of her rear. "I... I need..," she started again, gooseflesh rising from heated skin.

A single fingertip slid lower, over the softness of Harry's soft, slickened vulva, making the girl squirm. "I want you to tell me exactly what it is that you need," Snape said in an uncharacteristically soft voice.

The girl swallowed as two comparatively large fingers sunk deep within that sodden flesh, making her eyes close. "Yessss," she whispered, breath coming out in a long drawn out hiss, lost in the animal heat the oil had brought upon her. "Fuck me," she panted, out of her senses. Nothing mattered now except for those fingers moving within her and against her, her hips rolling wantonly against that violation. "Please, fuck me!"

There was a loud clash of glass shattering against stone as Snape swept the contents of his desk onto the ground. Harry gasped as Snape's fingers slid from her sticky heat, lifting her as if she weighed nothing at all and positioning her at the edge of his desk. With a wave of his wand, all of the lights in the room were extinguished, save for the light from a single candle at the side of the desk, the flickering light dancing over Harry's glistening skin.

Snape pulled his robes over his head, casting them them aside. His physique had not changed much from when Harry had last seen him in the Pensieve, slender and strong. His hands slid to Harry's wrists, holding her down as his lips met Harry's own. Harry found herself pressing up into that kiss, her tongue needfully slipping to his. The potion master's nails slipped down along her sides, fingertips gliding along her slender, coltish legs. His erection, long and slender pressed hard to her belly, throbbing with his heartbeat and own growing desire.

The boy turned girl gasped as the professor easily lifted her body, lifting and turning her. She was at the edge of the desk now, her rear presented. She trembled as she felt him slip up over her, fingers teasing at her sensitive nipples as the tip of his shaft nestled to her soft, sodden entrance. He was so hot there against her, teasing her with his presence, so close but not giving her what her body needed. "Professor..," she whispered.

"Severus," Snape replied in a soft voice, nipping at one of Harry's earlobes. "Call me Severus, Lily." His hips drove forward, holding Harry tight to himself as that tight, hot girlflesh opened about him. Snape held Harry as the former boy moaned at the new sensation of penetration, finding herself pressing back against that invading length.

The girl arched her hips back, rolling them against the professor's length. Her eyes closed as she focused on the sensation of being filled and the delicious friction as he began to move. A fingertip teased at the hard, swollen button her cock had become. "Mnhh, Fuck me, Severus," Harry gasped, grinding back against Snape even as his hips slapped against the soft skin of Harry's naked rear.

"I'm going to come, Lily," Snape hissed, his hands sliding along her slender legs, massaging the wrinkled soles of her feet with his thumbs. He gasped, lifting the girl's tiny body as he slumped back into his chair, the girl still impaled on his cock. He crushed her squirming body to his chest, biting the join of shoulder and neck as he pulsed again and again within the squirming girl, painting her vessel with hard jets of his essence.

Harry pressed close, eyes closed as her body tensed. Her first female orgasm came over her with the intensity of an earthquake, trembling in Snape's lap as her body spasmed about him. She turned as best as she could, facing away from him as she was, and nestled to his chest even as she felt him throb within her.

Some time passed, and Harry blinked, looking curiously up at Snape as she took inventory of her surroundings. Snape looked down at her widening eyes, rolling his hips and stirring himself within her.

"Everything all right, Potter?" Snape whispered to the girl, noting the growing look of horror on her face.

Harry moved quickly to scramble from Snape's lap. His hands found her shoulders, pressing her down hard into his lap and impaling her once more. She faced him now, his dark eyes looking into her own. "Enjoy that, did you, Potter? Like having me fuck you 'til you couldn't think?"

"NO!" gasped Harry, again trying to escape, but she was held fast at the shoulders by Snape's strong hands.

"Tell me, then, girl; why didn't you leave?" Snape slid a fingertip down along the center of Harry's sleek chest and belly, slowly encircling her clit. Harry squirmed and gasped, trying to escape the hand at her shoulder that was still holding her tight. "As I recall, it was you that undressed, that begged me to touch." His dark eyes met those pools of green once more. "Perhaps beneath the mannerisms of your oafish father there's a pretty little girl inside, desperate to get out."

"Don't talk about my father that way!" screamed Harry, as she finally managed to escape from Snape's lap. She began rummaging through her discarded robes, looking for her wand. "Going to tell Dumbledore," she grunted under her breath, her entire body shaking with rage. "Have you in Azkaban before you can blink, filthy Death Eater..."

Snape got to his feet, his slender body glistening where Harry's oiled form had pressed close. "It would seem then, Potter, that if you can't overcome that overbearing pride to see the truth for once in your life, I have but one more thing to say to you." Harry raised her head to see Snape standing over her, his wand pointed directly at her head.

"Obliviate."

Harry slowly came to from where he found himself sprawled on a cot the taste of pepper and ginger lingering in his mouth. He sat up, coming to the realization that he was still in Snape's office. The potions master was at his desk, wearing a pair of magnifying spectacles and carefully measuring out a series of fine, coloured powders.

"Ah, Potter," remarked Snape, peering over the tops of his glasses. "I see you're up. You had an unexpected reaction to the Potion of Silencing I had given you and passed right out. I let you sleep it off." He nodded. "Given the unusual circumstances, I shall consider our detention complete."

Harry absently nodded, getting up and gathering his possessions. He turned to the door to leave, and paused, pondering something that didn't seem quite right in the back of his mind. "Professor? Just what did happen, after I took that last potion?"

Snape looked up from his work, annoyed to be disturbed. "You crumpled, Potter. Out like a light. I conjured the cot so you could sleep it off, and you have been asleep until just now." He turned his attention back to the scales before him.

Harry turned to leave, and paused once more, turning back to Snape. "Nothing else happened then, sir? I kinda recall something, but can't remember what it was." Harry felt blood rush to his face, unbidden. He tugged at the neck of his robes, as if to get some air.

Snape lowered his head, a hand raising to rub at his temples. "If you'd been paying attention in class, Potter, you would know that too much capsicum in a Potion of Silencing can cause 'very vivid dreams' as a side effect. I imagine you saw yourself winning at quiddich, breaking curfew, or any of the other inane things you delight in." He removed his magnifiers, setting them on the desk. "Five points from Gryffindor for overstaying your welcome. It'll be fifty if you don't depart from my sight immediately."

Harry turned without another word and made a hasty exit. Snape watched the boy as he left, nothing the subtle sashay to his hips. Consciously or not, he would be back for another detention, and soon.
