"– but you can't tell your sister."

Padma Patil bit her lip, her dark eyes locked on Luna's. What the girl was telling her was absolutely insane and completely arousing. She'd never done anything this daring before, and certainly not without her sister's knowledge. The twins shared nearly everything. Joining the group would be a huge step away from that, but it would be worth the thrill the independence gave her. She and Parvati might be identical, but they were different in some very important ways. Her sister was a bit of a slut, for starters, and Padma had only been with a few people and had always been very discreet about. Added to the fact that Padma liked girls and Parvati only messed around with boys that made them distinct enough, without even adding the differences in their House allegiances, intellect and personalities into the mix.

Her mind raced over all the possible consequences of doing something so utterly exhibitionist and depraved. Group sex! Switching partners! Not to mention filming it all to show to the entire world afterward. Her stomach fluttered with excitement, and in that moment she knew she'd do it. Taking such risks was an utterly un-Ravenclaw thing to do, and she, Padma Patil, was going to do it.

"And Pansy is definitely interested?" she asked, her voice low. Everyone else in the room was asleep, but she didn't want to be overheard. Mandy Brocklehurst was a bigoted bitch, and Lisa Turpin would be all over her if she knew Padma preferred girls. Neither was a problem she wanted to have.

"She asked me to ask you," Luna said, a smile lighting her face. She was so happy to be bringing another Ravenclaw in. It felt strange to have such huge secrets from all of her dorm mates.

Padma looked at her in alarm, playing with the end of her thick braid self-consciously.

"She knows –"

"She didn't, don't worry," Luna said quickly, knowing how important it was to the girl to keep her secrets while here at Hogwarts.

Padma had already secured a coveted Potions apprenticeship after school, but she was still under her parents' thumb while enrolled at Hogwarts, at least nominally. While the twins were of age, their parents were very strict and traditional, not giving them much leeway to make their own decisions. As soon as her apprenticeship started, Padma would have her own money and be able to support herself, which was fortunate, since her family was likely to disown her when they learned she planned to break the arranged marriage contract they'd crafted for her when she was only an infant. Parvati dealt with her emotions by sleeping around while she could, but Padma had bigger plans; by studying hard and getting into the Potions program, she'd guaranteed her own freedom after school. She felt bad for her sister, who knew nothing of her plans, but Parvati was a shallow, silly bint, and Padma knew it. She'd settle into her arranged marriage to a wealthy heir without many problems.

"And this is discreet? It won't surface until after we're done here?"

Luna nodded, pulling out a piece of parchment with a contract on it. Once their numbers had started to multiply, Hermione had suggested having each person sign a confidentiality clause that would prevent them from sharing the secret with anyone the group didn't agree to tell. No one balked at signing it, especially since it mean they wouldn't be able to out the entire group if any subset of them got caught.

"Draco had his solicitor research how getting expelled from Hogwarts for unbecoming conduct would affect our N.E.W.T.s, and the short answer is that it can't. The N.E.W.T.s are Ministry-officiated, and there are spells in place that prevent any sort of tampering once the tests have been submitted. That means not even the Minister himself could revoke our scores once we've taken the tests."

Padma nodded, the knot in her chest loosening. The Potions Master she'd be apprenticing with was American, and it was unlikely he'd hear of the scandal, no matter how many waves it caused. Even if he did, she'd read enough about him to know he'd find it amusing, not embarrassing.

"Where do I sign?"

"As you can see, we've gotten a bit unwieldy," Harry called out over the hum of conversation in the Room of Requirement. Blaise and Draco had argued for Theo Nott's involvement, too, and the stocky Slytherin was perched on one of the sofas, flipping through the photos they'd taken so far with great interest.

"I think everyone here knows our two latest recruits, Padma Patil from Ravenclaw and Theo Nott from Slytherin," he continued, bowing to both of them as he said their names. "Welcome."

"Where's Seamus?" Blaise called out, taking a sip of the Muggle lager Theo had brought. His cousin ran a bar in Knockturn Alley, and often sent the Slytherin cases of both Muggle and wizarding alcohol. It was one of the reasons Slytherin parties were so popular.

"Detention," Hermione said, rolling her eyes. "He caught Ginny and Dean following him yesterday and the idiot hexed them. Slughorn saw and gave him detention tonight."

"Poor Shay," Luna said, hiding a grin. The thought that the boisterous Irishman would be chopping Potions ingredients while the rest of them had fun was amusing.

"His own fault," Draco said, shaking his head. Ginny had become a big problem for them, and Dean had joined her crusade to figure out what Harry, Hermione and Seamus were up to. Luckily they hadn't noticed Neville's absences generally corresponded with the other three.

"I'm sitting out tonight," Neville said suddenly, looking up from the parchment he had in his lap.

"What? Nev –"

He shook his head at Blaise, shoving the missive that had arrived by owl just before they'd left for the Room of Requirement at him. He read the letter, his face twisting into a snarl.

"Stupid bitch," he growled, handing the parchment back to Neville.

"It's from Susan Bones," Neville explained rolling up the letter and tossing it to Harry. "She's Professor Sprout's other assistant this term. She said overheard Ginny say she was going to ask me if we grow fluxweed in the greenhouses."

"What will you do?" Hermione asked, craning over Harry's shoulder to try to decipher the loopy writing.

"I'm going to offer to pick some for her," Neville said with a grin, waving away the incredulous looks. "Tonight's the full moon. I need to be in the dorms so she can find me."

Draco narrowed his eyes as he looked at the Gryffindor. Though the newcomers were probably lost, it was obvious to everyone else what Ginny was trying to do.

"What will you give her?"

Neville smirked, looking downright Slytherin as he gathered up the scroll and his robes and headed for the door.

"Daisy roots. They look the same."

Hermione's face lit up at the same time Draco's did. Blaise laughed, and Pansy and Theo blinked in amazement at the devious Gryffindor. Only Harry and Luna looked confused, and Harry rather suspected she was pulling an act just so he didn't feel left out.

"But don't you know what that will –"

Neville winked at Padma, his hand closing around the door handle.

"I'm only hopeless at making potions. I know exactly what all the ingredients do," he said, bowing to them with a flourish and scooting out the door.

It turned out that Blaise and Theo were the only ones who'd never been in the Prefects' Bathroom. Harry didn't ask Luna when she'd visited it, knowing her answer would probably be vague as to not implicate whichever partner she'd been with at the time. Everyone knew he'd been there with the golden egg a few years ago, though few realized it had become one of his favorite places to meet up with Draco on the sly, since as Head Boy Draco (and Hermione) had first dibs on its usage whenever he wanted.

"Perfect," Luna said, watching the enormous tub fill with hot, scented water. They'd decided not to use any bubbles, since those would potentially get in the way while they were filming.

"So we just –" Theo stopped uncomfortably, looking around the room and the motioning to the pool-sized tub.

"Don't be so uptight," Luna chided, pulling her robes off and draping them over a bench so they wouldn't get splashed. "It's no different than what we've done before."

She grabbed his hand, guiding it up underneath her vest. He relaxed slightly as his palm glided along warm skin, and he ducked his head, burying his face in her hair and breathing in her scent.

"Well, aside from the fact that this time it will be in water, on camera and with a group," she said cheerfully, ignoring the quiet snickers her comments elicited from the rest of them.

Harry watched Theo slide his palm up over her breast, sliding his lips from her hair to her neck and pressing a soft kiss against her pulse point with easy familiarity. He wondered if there was anyone left in the school Luna hadn't slept with. It was amazing, really, since managed to be discreet enough about it to avoid the reputations that Lavender Brown and Parvati Patil had gotten themselves, and he doubted either girl had the scorecard Luna did.

"I don't think Theo's ready yet to have anyone join them," Draco whispered in his ear, making Harry smile. "Give him a few more of these sessions and he'll likely come around."

Harry laughed, tilting his head back as Draco kissed his neck, his lips continuing down Harry's chest as he unbuttoned the shirt he was wearing.

"Did someone set up the camera?" Harry murmured, sighing at the way Draco's lips ghosted over his skin.

"Hermione," Draco answered, circling Harry's navel with his tongue before dipping lower, teasing along the waistband of his trousers.

"Good," Harry sighed, content to let Draco undress him. The blond unfastened his belt and trousers, and Harry stepped out of them, kicking his shoes and socks off as he did.

He crushed himself against Draco, the metal of the Slytherin's prefect's badge digging into his chest as he kissed him. Without breaking the kiss Harry loosened his tie, deftly working his fingers through the knot and slipping it off his neck, letting it slither to the floor over Draco's shoulder. He fumbled with the small buttons on Draco's French cotton shirt, mentally cursing the poncy design that stood in the way of him touching the pale flesh.

Blaise and Hermione were already in the water, watching the others undress with interest. She straddled his lap comfortably, the two of them sitting on the steps and enjoying the slippery sensations the scented oil Luna had added to the tub produced. Blaise let his hands skim up and down her wet back, caressing her absently as his attention drifted from couple to couple. She arched into his touch, her focus solely on Padma and Pansy.

The two girls were naked but for their knickers, locked in a passionate kiss, their bodies flush with each other. She could see Pansy's fingers dipping underneath the scrap of lace Padma was wearing, making Hermione sigh a little as the digits disappeared and the Ravenclaw moaned. She shifted in Blaise's lap, moving until his hard cock was nestled between her lips, its engorged head rubbing against her clit when she rocked forward.

Blaise looked up when he heard a nearby splash, winking at Draco when he saw the blond easing into the deeper end of the tub. Harry slid in beside him, pinning him against the wall and grinding their erections together. He moaned when their lengths slid easily against each other thanks to the oil, torn between wanting to be inside of Draco and wanting to watch everyone else from their current position. Whatever oil or potion Luna had used in the water was marvelous, since the water usually stripped away any lubricant he and Draco tried to use, making it difficult for them to actually fuck in the tub. He slid his cock down past Draco's balls, nudging against his entrance with the blunt head. Draco made a sighing sound, giving Harry one last kiss before twisting so he was facing the wall, supporting himself by resting his elbows on the side of the tub. Harry wasted no time taking advantage of the new position, running his cock teasingly up and down Draco's crack.

Theo knelt on the tile floor, drawing one of Luna's nipples into his mouth and teasing it to full hardness with his teeth and tongue, his eyes on Pansy and Padma in the corner. The Ravenclaw was writhing against the taller girl, her hips rocking back and forth as Pansy fucked her with her fingers. He groaned at the sight of Padma caressing Pansy's arse, her dark skin gorgeous against Pansy's paleness. Her hands continued to roam over the Slytherin, finally stopping as they cupped full breasts, pinching at rosy nipples and making Pansy gasp.

He looked up, unsurprised to see that Luna was watching the girls as well. He stood, pulling her into a quick kiss before leading her toward the tub and settling her on the side. He slipped into the water, positioning himself between her spread thighs. The water was deep enough that his position put him at the perfect angle to lick and nip at her creamy thighs, making her widen them and thrust her hips out, urging him toward her center. He complied, parting her lips with his tongue and seeking out her clit, gripping her hips to keep her in place when she started to thrash restlessly as he lapped at the hard nub.

Draco bit his lip as Harry pushed inside him with one forceful thrust, hissing as the motion forced his cock to hit the cool tiles at the side of the tub. Harry grabbed him by the hips, pulling him flush against himself and pumping his hips forward as he fought the buoyancy that kept trying to separate them. Draco leaned back against him, groaning when Harry wrapped his hand around his cock and stroked it firmly, punctuating each stroke with a hard thrust inside him.

Hermione moaned, pleasure rippling through her as Blaise rubbed his cock against her clit. She lifted herself out of his lap, the water rippling around her from Harry's thrusts, to give him more room to maneuver. Sensing what she wanted, he flipped her, bracing her against the wall of the tub with one arm and using the other to hold his shaft, applying more pressure this time as he worked it over her clit. The unfamiliar stimulation against the head of his cock was torture, and he squeezed the base of his erection, not wanting to come before she did but unsure of how close she was. He'd never tried anything like this before, but she seemed to be enjoying it, so he let her run the show.

Padma was the first to come, her cries echoing off the tile walls. She moved against Pansy's hand, riding out the throes of her orgasm as she buried her head against the curve of her neck, breathing in her scent. It was evident that everyone had been watching them from the way the groans in the room escalated, especially when she forced Pansy onto one of the benches, crawling between her opened legs and revealing Pansy's completely shaved lips. Padma ran her tongue over the smooth skin, making Pansy's thighs tremble slowly delved her tongue between her lips. The Slytherin jolted when she circled her clit with excruciating gentleness, knowing how hard it was for Pansy not to buck her hips. Padma laughed, dipping her tongue into her wet heat again.

Luna whimpered as she came, her legs locked around Theo's head as he flicked his tongue roughly against her clit. He relaxed his tongue when she started to quiet, running the flat of it over the nub in lazy circles until she groaned again, pushing him away when the stimulation became too much. He grinned, pulling on her legs until she slid into the water with him. She wrapped herself around him, sighing as he slid into her wet heat as she kissed him, tasting herself on his swollen lips.

Harry buried his face in Draco's neck, kissing the soft skin as he thrust into him. He couldn't get the leverage he needed to fuck him as hard as he would have liked, but he was enjoying the slow build of his orgasm. They usually didn't take this much time with each other, so it was a nice change to be gentle instead of rough. He felt Draco's orgasm begin before the other boy started to moan his name, his already tight channel closing even more around his cock as Draco bucked against his hand. Harry came a few moments later, unable to hold out as the aftershocks of Draco's orgasm squeezed him convulsively.

Blaise panted, knowing he wouldn't be able to stave off his orgasm much longer, especially after not watching Harry and Draco come. He tried to warn Hermione, but she kissed him instead, and he heard her start to moan as her own orgasm drew nearer. It tore at the last of his self-restraint, and he sped up his motions, his hot come spurting against her clit as he rubbed it against it. It sent Hermione over the edge, and she clung to his neck, making soft mewling sounds as she shuddered against him.

Theo and Pansy both came at the same time, though her cries were louder than his. He drove inside Luna, burying himself to the hilt as he started to come, arms wrapped around her waist to hold her in place. She moved against him, drawing his climax out. Both of them watched as Pansy writhed on the bench, Padma's hands holding her hips down to keep her from bucking up too much.

No one seemed to know what to do as the last of the cries of pleasure died down, leaving only the sound of their heavy breathing. Luna pressed a kiss to the side of Theo's mouth, unwrapping her legs from around him and shimmying out of his arms. She swam toward the steps, unconcerned with her nudity as she climbed them and strode toward the camera.

"Padma Patil, Pansy Parkinson, Luna Lovegood, Theo Nott, Harry Potter, Draco Malfoy, Blaise Zabini and Hermione Granger having sex in the Prefects' Bathroom," she said, wringing water out of her hair. "Cut."
