Draco and Hermione were working at the same table in Potions, their smoking cauldrons side-by-side. Neither took any notice of the other, both absorbed in the complicated instructions they were following. Harry surreptitiously panned the camera to the chalkboard at the front of the classroom, zooming in on the ingredients outlined there – everything needed to make Orexis Adaugeo, a potion that magnified latent desires and pushed them to the forefront of the imbiber's mind. It was one of the more volatile potions on the seventh-year N.E.W.T. syllabus.

He shifted slightly, moving the camera back to the unlikely lab partners, who were still laboring over their cauldrons. Hermione's face was a mask of concentration as she stirred the violet brew exactly fifteen times, careful to keep the tip of her wooden spoon in contact with the bottom of the cauldron, as the instructions specified. Even Draco's usual sneer was absent, his eyes focused on his own bubbling potion, gleaming white teeth visible as he bit his lip absently, his attention centered on his task.

Harry stifled a giggle, angling his shoulder so Seamus couldn't see what he was about to do. He and Luna had taken Hermione's plan for the Potions classroom scene and modified it slightly – neither Draco nor Hermione knew he was filming this. Things are about to get very interesting, he thought with an ill-concealed grin.

He'd never really watched Draco or Hermione brew, and even he had to admit it was a thing of beauty. Their movements were graceful and precise, their attention rapt. Neither had suspected anything when he asked Draco to take his place as Hermione's partner for this lab, easily accepting his explanation that he and Seamus had studied the potion together the night before and wanted to brew it together.

Luna nudged him with an invisible elbow under the table. She wasn't in their Potions class, but she'd snuck in under Harry's Invisibility Cloak, lounging against Harry's shins as they waited for just the right moment. He kicked his foot out, catching her in the side. She'd taken advantage of her position several times already during the class, breaking Harry's concentration by running warm hands across his legs and crotch, heightening the excitement he already felt in anticipation of their prank.

Harry glanced at Seamus again, reaching his hand under the table when he was satisfied the Irish wizard wasn't watching. A cool vial slapped against his palm, already uncorked. All Harry had to do was levitate it into either Hermione or Draco's potion and sit back to watch the fireworks.

Gripping his wand under the table, Harry guided the vial of diced ginger root toward Hermione's cauldron. She was directly in front of him, which made her potion an easier target to reach surreptitiously. He was careful to keep the vial level with the desk, creeping against the wall.

Luna, who had been monitoring Hermione's potion's progress, nudged Harry gently just seconds after the liquid achieved the lemony yellow color that signaled a successful brewing of Orexis Adaugeo. The ingredient itself wouldn't affect the potency of the potion, but adding ginger root to anything with Jabberknoll Feathers would cause an explosive reaction – just what they were counting on.

The vial tipped over the side of the cauldron, dumping a small amount of the pale ingredient into the mix. Neither Hermione nor Draco noticed. Harry flicked his wand, Vanishing the vial before the potion began to bubble ominously, wisps of orange smoke emanating from it. Startled, Hermione narrowed her eyes at the now-roiling liquid, exchanging a bewildered glance with Draco just before the entire cauldron heaved, exploding violently, and covering them both with the fragrant potion. There was absolute silence for a few seconds after the explosion, and widened grey eyes rose to meet startled brown. A few more beats passed before both Hermione and Draco turned to look at Harry, obviously realizing his part in the mishap.

Luna was crouched on her heels under the table, releasing a potion that would fill the room with acrid smoke, simulating the reaction a dangerously unstable ingredient like Entrumpment Horn would have had if added to that particular potion. Harry watched Slughorn's progress to the back of the room, his robes billowing out behind him as he hastened toward them.

Only a few seconds had passed, but the classroom had already erupted into mass chaos. Students were climbing over each other in their rush to escape the smoke, and Slughorn was yelling orders about containment and isolation – no one who had been touched by the botched potion would be allowed to leave the room until its effects were known. Harry and Luna both focused on the scene directly in front of them, noticing the exact moment when Draco's hands trembled, and Hermione gasped, her pupils dilating.

Both sent a shocked glance toward the camera, and Harry smirked in response. Sure, they could have acted this part out, but it was so much better since it was real. Harry angled the camera up slightly, careful to catch their outraged reactions. He knew they had just a few minutes before the pull of the potion would be unbearable; he and Luna had tested it out themselves the night before.

A few more seconds ticked by, and Hermione and Draco began to focus on each other. The rest of the room melted away from their consciousness – the potion working on their minds, drawing out their wildest sexual desires for each other, just as Harry and Luna had hoped it would. Neither responded when Slughorn reached them, keeping a safe distance away in case the potion's fumes were still volatile, asking how badly they were injured.

"I have it all over me, too, Professor," Harry offered, showing Slughorn his wet robes. He'd taken advantage of the chaos to douse himself with a quick Aguamenti charm. "It doesn't hurt, but I feel kind of funny. I think you'd better seal the classroom, at least until we figure out what the effects are."

"Harry, my boy, how selfless of you!" Slughorn said, backing away.

Harry smirked. There was little to no chance they'd have gotten away with this with any other professor, but Slughorn had a very healthy sense of self-interest. He and Luna had known he'd take the first opportunity to leave that Harry gave him.

"I think the spell you'll want to use is Loginquitas Claudo," Harry said, citing a Quarantine Spell Luna had read about in Potions Monthly. "Professor Snape used it a few times when potions got out of hand."

Slughorn nodded, bringing his arm up to shield his mouth and nose from the harmless smoke. "Very brave, Harry. Always thinking of the greater good. Fifty points to Gryffindor for your quick assessment."

Harry shifted, blocking Slughorn's view of Draco and Hermione, who were both unsuccessfully trying to fight the effects of the potion. Draco's hands were fisted, his knuckles white with the effort of not reaching out to touch Hermione, who had her eyes squeezed shut and her lips pressed tightly together.

"Thank you, Professor," Harry said, trying to keep his amusement out of his voice. "I'll send my Patronus with a message when the classroom is safe again."

"You do that, my boy," Slughorn said, wrenching the classroom door open. "I'll have Poppy standing by."

The door slammed behind him, and Harry heard Slughorn use the incantation he'd suggested to lock them inside. Luna sprang up from her hiding place, adding several other Locking and Silencing charms to the door for good measure.

"You utter bastard," Draco ground out, his teeth clenched.

"I could kill you for this, Harry," Hermione said, her voice shaking.

Harry merely shrugged, resting the camera on a pile of books so it had a better shot of them. Luna sank into the chair next to his, her eyes dancing with laughter and desire.

"You won't be able to fight it much longer," she said, cocking her head as she watched the seconds tick by on a nearby clock. "Harry and I lasted exactly 387 seconds. That's right … about … now."

Neither Draco nor Hermione moved, the silence heavy in the deserted classroom. Suddenly, Draco lunged at her, his hands tearing at her school robes, fingers fumbling with her gold and crimson tie. Her hands fisted in his hair as their lips came together in a violent kiss, holding him in place.

They broke apart just as suddenly, panting as they concentrated on disrobing, focusing on their own clothes by some silent agreement. Draco looked over at Harry, his eyes flashing.

"I hate you," he spat, hopping on one foot as he tried to wrench his trousers off without first removing his shoes.

"You just wait," Hermione warned, her voice muffled by the jumper she was pulling over her head. She tossed it in the corner, her fingers moving to the clasp of her bra. "You'll pay for this, both of you!"

They continued berating Harry and Luna, their naked bodies wrapping around each other as they groped and stroked, breathless from alternating between kissing and yelling. Harry smirked as he watched them, his lips curving into a smile every time one of them actually managed an incomplete insult.

" – beyond inappropriate –" Hermione was saying, the rest of her words lost as Draco thrust an eager tongue into her mouth, his hands cupping her breasts. She arched and moaned as he gently rolled one of her nipples between his thumb and index finger, teasing it to a hard peak before moving on to the other.

" – wish you'd never been born –" Draco muttered, kissing his way down Hermione's neck, tiny red welts blooming across the skin as he nipped at it with sharp teeth.

Draco swept his free arm across the desk, sending the two pewter cauldrons of Orexis Adaugeo crashing to the stone floor. Harry and Luna jumped up, only barely managing to miss being coated by the splatters. Pale hands gripped Hermione's slender waist, lifting her effortlessly up onto the flat surface. She wrapped her legs around Draco, drawing him closer as she claimed his mouth with urgent kisses.

"When I'm through with you, Harry Potter –" she gasped as Draco's mouth broke away from hers, her words abruptly ending when he closed his lips around her nipple, drawing the rosy peak into his mouth and biting it lightly with his teeth.

Harry leaned forward, engrossed in the scene before him. Hermione was nearly as pale as Draco, and the sight of their luminous bodies so intimately intertwined sent chills down Harry's spine. He felt a rough pulse of desire at Draco's harsh groan when Hermione's hand closed around his cock, his stomach tightening with lust at the familiar sound.

They were kissing again, though Harry thought that an inadequate word to describe the way Draco and Hermione were frantically devouring each other. His pulse quickened as he remembered the almost frightening need he'd felt under the effects of the potion with Luna – their frenzied lovemaking in the Divination classroom had left them both reeling the night before. Harry smiled as his glance flitted to the camera; he was sure Draco would forgive him when he watched the film of that encounter. He knew it had been every bit as hot as the scene in front of him. Which is definitely saying something, he thought with a grin.

Hermione was splayed on the desk, her legs open as Draco knelt between them, his tongue buried deep inside her. Deft fingers massaged her swollen clit, joined occasionally by Draco's talented tongue. Hermione was gasping, her legs trembling with pleasure. She grabbed Draco by his hair, guiding him back up her body so she could kiss him deeply, rubbing her slick clit against his rock-hard erection.

She sat up slightly, helping him maneuver into position so he could easily enter her. Her head fell back as he slipped inside, and Draco took the opportunity to kiss her neck, pressing his lips against the frantic beat of her pulse.

"Oh my God, Draco," she moaned, her hands gripping his shoulders, her legs wrapped around his waist to pull him deeper inside.

"Fuck, Hermione," he murmured against her neck, breathing in the sweet and clean scent of her skin.

They moved together at a frantic pace, both desperate for release, their arousal spiked to a near-unbearable level because of the potion. Draco's mouth captured Hermione's as he thrust into her again and again, swallowing her cries of pleasure.

"Draco, harder!" Hermione moaned, pulling away from his kisses to rest her sweaty forehead against his shoulder.

He obliged, pulling her closer to the edge of the desk so he could adjust his angle, plowing into her as hard as he could, his lips pressed tightly together as he tried to stave off his own orgasm until she had found her release.

Moments later they were both there, gasping and moaning unintelligibly as they peaked, their lips crashing together for one last desperate kiss as Draco pumped his release into Hermione and she shuddered and convulsed around him.

Draco's movements slowed, and their kiss lost its urgency, their lips softening as it morphed into something sweeter and slower. They broke apart, panting, when the last of the aftershocks had pulsed through both of them.

"You are dead to me, Potter," Draco said, pulling back to rest his head against Hermione's chest, their bodies still joined.

Harry laughed, already looking forward to whatever revenge Draco would seek. Harry knew from experience the Slytherin was very good at retribution, and he always followed through on his threats.

Hermione sighed, gently pushing Draco away so she could free herself and hop down from the desk. She gathered her robes, blushing darkly as she donned her clothing.

"This was not the plan," she chastised, crawling under the desk in search of one of her shoes.

Luna jumped up, smiling brightly as she walked in front of the camera.

"Hermione Granger and Draco Malfoy fuck during Potions class," she said, turning to wink at Draco. "Cut."

Hermione and Draco dressed quickly while Luna and Harry set the classroom to rights. When the the last remnants of the potions had been cleared away and all the ingredients and supplies returned to their rightful places, Luna tossed the Invisibility Cloak over herself and moved toward the door. Harry followed, undoing the charms she'd placed there earlier before sending his Patronus to tell Professor Slughorn the danger had passed.

A minute or so later, he heard the professor cancel the Quarantine Spell, and the door swung open, admitting a very anxious mediwitch and a chagrined Potions professor. Poppy had obviously given Slughorn a piece of her mind for abandoning his students.

"Let me get a look at you, then," she said, shushing their objections as she cast diagnostic charms over the three visible students.

She tutted as the results came back, her eyes narrowed as she noted Draco and Hermione's elevated blood pressure and pulse.

"No damage I can see, but I'd like you to come to the Hospital Wing all the same. I'd like all three of you to spend the night under observation."

Draco opened his mouth to protest, abruptly shutting it before he voiced his objections. Harry felt his own pulse jump at the feral gleam in the blond's eyes, his cheeks coloring when he realized the mediwitch's monitoring spell picked up the increase.

Hermione's lips quirked when she heard Luna's girlish giggle from under the cloak, both of them suddenly sure they knew just exactly what Madam Pomfrey would likely be observing in the Hospital Wing that night.
