"We're going to be expelled after the fact for this," Hermione groaned, letting her head hit the desk in front of her. All eight of them were gathered in a circle in a dusty, disused classroom, plotting their next move. It hadn't taken long to bring Blaise and Neville up to speed, and the pair had embraced the mission whole-heartedly. "Can they take away your N.E.W.T.s? I mean, we'll have sat for them already, but we won't have the results by the leaving feast. Could McGonagall void them?"

Draco laughed, pulling Hermione's desk closer to his so he could sling his arm around her shoulder.

"That would be up to the Ministry, not the Headmistress. And I doubt anyone will want to call any more attention to what we've done, which voiding our N.E.W.T.s would certainly do."

Hermione sighed, jotting down a few notes in the book in front of her. What they were about to do was very stupid, but it was also very exciting. It would be a huge coup if they pulled it off – or a reason to expel them if they didn't.

"Harry –"

"I've already tried the Parseltongue spells to get past the gargoyles and put the paintings to sleep. They work."

"But will they work on those portraits? They aren't the run-of-the-mill ones that are in the rest of the castle, Harry," Hermione said sharply, flipping through her worn copy of Hogwarts: A History to find some passage she thought was relevant. "Those are soul portraits. They –"

"Are infused with a bit of the subjects' magic, thereby making them sentient and able to hold the memories of each Headmaster and Headmistress if they chose to endow them to the school. Yes, I know."

Hermione scowled but didn't respond, motioning for the others to continue.

"I'll be at the base of the stairs with the map, just in case McGonagall wakes up in the middle of the night with the insane urge to visit her office," Seamus said, his displeasure at being left out of the main action clear in his tone.

"I will be holding a shield around the office to make sure none of the ghosts or Peeves can get in," Pansy said, looking up from a sheaf of parchment with complicated runes and Arithmancy equations on it.

"I'll be in the office making sure the portraits don't wake up," Harry said, grinning cheekily at Hermione.

"I'll be filming," Luna said brightly, aiming a saucy wink at Blaise.

"And the rest of us will be participating," Draco said, drumming his fingers against his desk. "Everyone clear on how they will be getting out of their dorms?"

Seven heads nodded, and Draco gave a hum of approval. This was by far their most daring escapade, and it also required the most planning. The stakes were high if they got caught, but everyone had voted that it was worth the risk. Even Hermione had been willing when they started planning two weeks ago, though it seemed like she was getting cold feet now.

"Any objections?" he asked one last time, his gaze traveling around the room. "Hermione?"

She shook her head, offering him a small smile.

"Excellent," Draco said, his eyes dancing with excitement. "Be in your places at 2 a.m. tomorrow."

Blaise had Neville pushed up against a tapestry on the second floor, his hand inside the Gryffindor's trousers. They'd been snogging for a good twenty minutes, and things were heating up fast. Neither of them heard the quiet footsteps approach, so they jumped when a familiar drawl broke the silence in the darkened corridor.

"Out after curfew," Draco sneered, and both their eyes were drawn to the shiny Head Boy badge on his shirt. "Blaise, a Gryffindor? I should take points from Slytherin for bad taste as well as breaking the rules."

They'd agreed to be very careful about actually taking points, since it was well within their purview as Head Boy and Head Girl for Draco and Hermione to do so. A careless slip of the tongue tonight could cost Gryffindor and Slytherin actual points, and no one wanted to have to explain that in the morning.

"Have something to say, Longbottom?" Draco spat, watching Neville sputter in indignation. "What shall I do with you, eh? So many possibilities. Tell me, Longbottom, what do you think your punishment should be?"

"Don't say anything, Neville," Hermione said, startling all three of them with her nearness. She'd snuck up on the group while they'd been arguing. "Don't give the prat more reason to take points."

"Language, Granger," Draco tsked, shaking his head. He slapped his wand against his palm, pacing slowly in front of the two disheveled boys.

"The penalty for being caught out after curfew is detention, Malfoy," Hermione said, her voice full of indignation. "Just take the points and assign them both a detention with Professor McGonagall."

Draco hummed, narrowing his eyes as he looked at her.

"Wouldn't you rather your House not lose points, Granger?" he asked, a smirk curving his lips.

"What, you'll forget this happened? Not bloody likely, Malfoy," she scoffed, scowling at him. "More like you'll report me for letting a fellow Housemate off too easily. No, they need to be punished. Perhaps just detention, then, if you're so eager to keep your own House points?"

Draco grinned, slipping his wand into its holster.

"I have just the thing, I think. Detention in McGonagall's office, now."

Hermione gaped at him, sheathing her own wand now that his was out of sight.

"Now? It's 2 a.m., Malfoy. The Headmistress would hardly thank us for waking her to supervise a detention in the middle of the night."

Draco shrugged elegantly, the small smile still on his lips.

"So we don't. We supervise their detention. It's well within our duties as prefects."

Hermione studied him appraisingly, finally nodding. Neville made a concerned yelp, but Blaise cut him off, nudging him to follow the Head Boy and Head Girl as they made their way toward the Headmistress' office.

Harry was there already, under his Invisibility Cloak. He hissed out the spell he'd found in an old book in the Restricted Section, relieved when the stone guardians at the base of the Headmistress' staircase went lax. The sound of stone grinding against stone as the staircase opened was unbearably loud in the quiet corridor, but Seamus, who was monitoring the map in a small alcove nearby, gave them the signal to continue.

"Up," Hermione said primly, standing back to let Neville and Blaise go first. She and Draco took up the rear, and she felt a whisper of cloth against her bare legs. Harry had obviously joined them on the staircase.

The portraits were all fast asleep, and none of them so much as twitched when Hermione lit the lamps around the office. Harry had been up earlier to spell them asleep but hadn't wanted to spell the gargoyles, leaving the office unguarded, until the others had arrived.

Draco settled himself in the Headmistress' chair, nodding to Hermione to make herself comfortable on the sofa. She glared at him, choosing to lean against the desk instead.

"What shall we have them do? Lines?" she asked, looking over her shoulder at the blond.

Draco shook his head, steepling his fingers thoughtfully.

Hermione sighed in exasperation, crossing her arms tightly across her chest.

"I don't feel like supervising them all night, Malfoy. Propose a punishment so we can get this over with."

He stood, pulling open a drawer in McGonagall's desk and retrieving a quill. He twirled it in his hands, letting his wand drop from his wrist holster and Transfiguring it into a wooden paddle with a flourish.

"You can't mean to paddle them," Hermione said, her eyes wide as she watched Draco wrap his fingers around the handle.

"That's not a Hogwarts-sanctioned punishment," Blaise said haughtily, raising his chin as Draco stalked toward him.

"Actually, it is," Hermione said, frowning in concentration. "It was commonly used as a deterrent up until the early 1900s, when it fell out of favor with the Headmaster at the time. But it's still on the books as acceptable."

Neville paled, watching Draco caress the light-colored wood with his fingertips. The paddle was short but thick, and he felt his pulse jump at the thought of it smacking against his arse. He'd never been spanked before, but his cock was already filling in anticipation.

"My mother won't stand for this," Blaise said, gasping when Draco nudged the back of his knees, sending him sprawling across the arms of a chair in front of the desk.

"No?" Draco drawled, his tone mocking. "She won't agree that her pure-blood son deserves to be spanked for being caught out with his hand down another boy's trousers?"

Blaise shivered when Draco's hand caressed his arse, the gentle touch making his nerve-endings scream. He wasn't prepared for the sharp crack of the paddle that followed, and he cried out, his hands gripping the material of the chair tightly.

"Well?" Draco asked, raising the paddle menacingly. Blaise saw the blur of motion out of the corner of his eye and braced for another blow.

"No! She wouldn't," Blaise said through clenched teeth, trying desperately not to react. The paddle came down again, harder this time, and he ground against the chair, hissing out a breath when his hard cock pressed against it.

"Don't!" Neville shouted, taking a step toward Draco. He could tell from the tenor of Blaise's cries that the boy was enjoying himself, but he knew he needed to make at least a token protest.

"You're next, Longbottom," Draco said with a feral grin, bringing the paddle down against Blaise's clothed arse once more. "We'll see if you enjoy this as much as your boyfriend here does."

"Enjoy it?" Blaise sputtered, struggling to stand. "Are you mad?"

Draco made a tutting sound, shaking his head at Blaise's words.

"Granger," he said, and Hermione stepped forward, looking at him questioningly. "Why don't you see how much Blaise is enjoying his spanking?"

Hermione raised an eyebrow in challenge but complied, pulling Blaise up into a standing position and running her hand across the front of his tented crotch. She wrapped her fingers around his length, giving his cock a light squeeze as she weighed his erection in her hand.

"I think he is enjoying it," she said, smiling when he groaned and thrust into her hand as she applied more pressure. "Should he be enjoying his punishment, Malfoy?"

Draco smirked, forcing Neville to kneel in front of him across an ottoman, his arse up in the air. He brought the paddle down quickly, hard enough that tears sprung in Neville's eyes. He bit his lip, determined not to cry out, even as Draco spanked him again, harder still.

"Do you like watching your boyfriend being punished?" Draco asked Blaise, whose gaze was riveted on the Gryffindor. He smirked when he realized Hermione's hand was still firmly covering the front of his trousers, caressing him through the light wool. "Don't lie. Granger would know."

Blaise murmured something, prompting Draco to spank Neville again. The dark-haired boy bit his lip hard enough to draw blood but remained silent. The last smack had been dangerously close to his balls, and his cock throbbed with excitement at the tingling, stinging sensation it had produced.

"What was that, Blaise?" Draco asked innocently, raising the paddle again but bringing it down softly, using it to stroke Neville's arse.

"Yes," Blaise said, gritting his teeth as Hermione started rubbing him through his trousers in time with the strokes of the paddle.

"Have they been punished enough, do you think?" Draco asked Hermione, his tone conversational.

She pretended to mull the question over, her fingers still kneading Blaise's erection.

"What do you think, Longbottom?" Draco asked, pressing the paddle against the abused flesh of his arse. He cupped one of his arse cheeks with his other hand, his own cock jumping when he realized he could feel the hot skin through Neville's trousers. "Learned your lesson?"

Neville responded with a strangled gasp as Draco's long fingers delved lower, caressing his balls through the fabric.

"I think they've both rather enjoyed their spankings," Hermione said thoughtfully, releasing Blaise and taking a step back.

"That hardly seems fair, does it?" Draco asked, letting go of Neville and standing. The dark-haired Gryffindor stood as well, wincing as the movement pulled at tender skin. "Perhaps we should get some enjoyment of out it too, eh, Granger?"

She tilted her head thoughtfully, pausing a moment before standing on her toes and wrapping her arms around Blaise's neck, pulling him in for a hard kiss. Neville gaped at them for a moment, startling when he felt Draco's hands snake around his waist and fumble with his belt.

"Should we watch them or participate?" Draco whispered in his ear, licking and nipping at the full lobe. Neville shivered, shimmying out of his trousers and pants to help speed things along. He cried out when Draco's cool hand splayed over his arse, the touch bringing both pleasure and pain.

Neville turned, kissing Draco deeply as the other boy unbuttoned his shirt. He heard Blaise's heavy belt buckle hit the floor behind them, and the unmistakable sound of Hermione moaning. Not wanting to miss the show, Neville broke the kiss, his own hands moving to divest Draco of clothing while he looked over his shoulder at the scene playing out behind them.

Blaise was naked, his cock jutting out of a nest of dark curls. Hermione's shirt was unbuttoned, her lacy bra visible. Blaise had one hand up her skirt and one inside her shirt, and she was writhing against him, her back to him as she faced Draco and Neville.

"Fucking beautiful," Draco murmured, his breath hot against Neville's neck as he bent to kiss and suck on the skin there.

Neville relaxed back against Draco, letting the blond's cock nestle between his arse cheeks, which were still on fire after the paddling. He pressed against him, gasping at the pain that had his cock pulsing. He'd never considered the fine line between pain and pleasure before, but it was a delicious balance.

Hermione cried out again, her hands fisting at her sides as Blaise pleasured her, his thumb circling her clit as his fingers slid inside her wet heat. Neville started forward without thinking, helping Draco unbutton the rest of Hermione's shirt and unfasten her bra, exposing her hardened nipples and full breasts. She groaned when Neville drew one of her brown nipples into his mouth, teasing it with his tongue.

Draco dropped to his knees, wrapping his lips around Blaise's neglected cock. The boy moaned, thrusting his hips forward as Draco took him deeper into his mouth, caressing the soft head of his erection with his tongue.

Neville followed Draco's lead, kissing a trail from Hermione's chest down to her hips as he knelt. He nipped at Blaise's fingers, shoving them out of the way as he delved his tongue between her lips, flicking it over her clit in circular strokes that made Hermione's thighs tense and her breathing grow harsh.

"Fuck, yes," Blaise growled, torn between watching Neville or Draco. Hermione leaned against him, whimpering as Neville increased the pressure and speed of his strokes. It was overwhelming to watch Neville pleasure Hermione while Draco worked on his own cock, and it didn't take much longer for Blaise to be spurting his release, crying out nonsensical words as he came.

Hermione followed soon after, her hands clenched in Neville's hair as she rode his tongue to orgasm, her face flushed and hair wild. She collapsed against Blaise, almost sending them both tumbling to the ground. Strong arms wrapped around her, helping her keep her balance. She knew without opening her eyes it was Draco, and she let him lift her up onto the edge of the desk, wrapping her legs around his waist as he claimed her mouth in a fierce kiss.

Blaise sank to the ground, seeking out Neville. He loved that he could taste Hermione on Neville's tongue as he kissed him, keeping an eye on what she and Draco were doing nearby. Neville pressed his erection against Blaise's hip, thrusting against him as he watched Draco's cock slide into Hermione's willing body. His knees hurt in their current position, but he couldn't be bothered with moving after Blaise's hand snaked between their bodies, wrapping around his cock and stroking him in time with Draco's thrusts. Neville lowered his head, resting it in the crook of Blaise's neck as he felt his orgasm begin to build, his cry muffled as he came, shuddering against Blaise.

The other boy pumped him lightly, seeing him through his orgasm and coaxing a few more aftershocks from him. Blaises' eyes drifted shut when Neville's head rose, his mouth closing over his in a sweet, lingering kiss.

Hermione's hand slipped against Draco's sweaty back, the other clamped around the edge of the desk to keep his thrusts from sending her across the flat surface. She locked her legs tighter around his waist, pulling herself up so she could press kisses against the pale column of his neck. She could tell he was close from the frenzied pace of his thrusts, and she grabbed his hair, forcing him down for a kiss. He groaned into her mouth, his hips pumping furiously as he came buried deep inside her.

She let her legs slide down his thighs, wrinkling her nose as she finally realized how sweaty they both were. He helped her hop off the desk, smirking when he thought about how upset McGonagall would be when she realized exactly what they'd been up to in her office.

"Head Boy Draco Malfoy and Head Girl Hermione Granger giving Blaise Zabini and Neville Longbottom detention in the Headmistress' office," Luna said, stepping in front of the camera. "Cut."

Harry grinned, tapping the device with his wand to turn it off. He'd certainly enjoyed watching the "detention", though it had left him painfully aroused. From the look Draco was giving him, he was pretty sure that would be remedied soon.
