Harry grabbed his map, frowning when the dot labeled Ginny Weasley still hadn't moved from the sofa in the common room. He'd planned to meet Draco and Luna down at the lake nearly twenty minutes ago, but he hadn't been able to get away because the youngest Weasley had stationed herself downstairs as a guard.

He sighed, flopping back down on his bed. Ron and Dean were already fast asleep, but he could see a thread of light coming from the closed hangings around both Neville and Seamus' beds. It was well after midnight, and he was surprised that anyone else was awake.

Harry closed his eyes, letting his mind wander down to the lake. He'd lent Draco his cloak so he could escape from Slytherin without being noticed, but that seemed to have been a grave miscalculation. Ginny had been following him around for the last week, ever since he and Seamus had filmed the scene in the Great Hall. She had no idea what was going on, but it seemed like she'd probably cotton on sooner or later if she kept up with following them around. That or they'd not get to finish – no one could agree on whether or not to initiate her into their little group. Harry and Hermione were against it, since she felt like a little sister to them. Pansy and Draco were ambivalent, though their initial feeling was not to let any more Gryffindors into the group until they'd balanced it out with a few more from Slytherin or Ravenclaw. Everyone could agree that Hufflepuff was best left out of their illicit venture. Only Seamus and Luna thought it was a good idea to bring Ginny into the fold, though Harry suspected their reasons were different. Luna was tired of being the youngest in their group, and it was no secret that Seamus was interested in Ginny.

Harry's eyes shot open as the bed dipped, and he breathed a sigh of relief to see Seamus' familiar face leaning toward him in the gloom. He hadn't lit his torches, since he'd pretended to go to bed hours ago so he could slip away. Not that it had worked.

"She down there again?" Seamus asked, his voice low so as not to draw Neville's attention or wake the others.

Harry pulled the map out again so Seamus could study it. He held his lighted wand up to the old parchment, grimacing when it showed Ginny still in the common room.

"We should just tell her," Seamus said, lowering his wand and extinguishing the light. He'd doused his own torches, so the only light in the room came from the moonlit window and the faint glow from Neville's bed hangings.

"We all have to agree, and we don't," Harry sighed, falling back on his pillows. He was now nearly forty minutes late.

"Send Seamus down to distract her," another voice said softly, making both Seamus and Harry jump. Neville had drawn aside his curtains, his face illuminated in the darkness.

Seamus gaped at him while Harry desperately fished for excuses, both of them regarding Neville with silent horror.

"Malfoy won't wait forever, even if Luna's there to amuse him," Neville said knowingly, closing the book he'd been studying with a thump and standing. He scanned the room, his gaze lingering on Ron and Dean's closed bed hangings. He extinguished his torches with a quiet spell, padding softly over to Harry's bed on bare feet so he could whisper. "He's not exactly patient, is he? And Ginny's stubborn, you both know that. Have Seamus distract her and I'll help you slip out."

Panic flared in Harry's mind as he tried to figure out when he'd said Draco's name that evening – he was sure he hadn't. They were extremely careful not to talk about each other unless they were alone with the few friends who knew, so how could Neville have found out? And why was he so calm about it?

"I have eyes," Neville said, rolling his eyes. Harry's own green eyes widened at his words. He and Draco were discreet. No one had any reason to suspect them, or so he thought. "I'm fairly sure no one else knows, though Blaise Zabini might suspect. You should probably induct him into your little group soon. He'd be up for it, if the stories I've heard about him are true. Did you know that two half-Veela got thrown out of Beauxbatons last year for having a threesome with him? It was over the summer, but apparently Madam Maxine is strict about that sort of thing."

Harry and Seamus exchanged a meaningful glance. No matter how Neville had managed to find out what they were up to, it sounded like he had full knowledge of their exploits. Which meant he was the next logical inductee, not Zabini.

"So, Nev," Seamus said casually, grinning when the other wizard blushed.

"I thought you usually all had to agree?" Neville said, surprising them with his snarkiness. He'd changed a great deal after the war, becoming much less shy and more confident in himself, but he had still remained the soft-spoken boy they known for years. Or so they thought.

"Extenuating circumstances," Harry said, still trying to wrap his mind around mild-mannered Neville's sneaky side.

"We're a package deal, I'm afraid," Neville said, his lips twitching into a grin. Far from being shocked at their offer – or at what they'd been getting up to – Neville seemed to have expected the invitation. "Blaise. We're a package deal."

Harry was shocked to find Draco waiting for him out by the lake. The blond didn't even look upset, which tipped Harry off to what must have happened in the dungeons. Apparently Zabini hadn't wanted to chance that Neville's meddling would get them both in; it looked like he'd talked with Draco as well. Luna was, somewhat predictably, engaged in what looked like a two-sided conversation with the Giant Squid. She was perched on the edge of the shore, her head cocked as though she was listening to something the great slimy beast was saying. And damned if the thing wasn't gesticulating with its tentacles, too. Harry shook his head, quickening his pace.

"So, Blaise and Longbottom?" Draco asked as soon as Harry was close enough to hear him.

"Apparently," Harry said, his mind still whirling at the thought of Neville involved with the school's most notorious playboy. He hadn't even known Neville liked men, let alone that he'd have the courage – or desire – to attach himself to someone like the shifty Slytherin.

"At least Pansy's getting her wish," Draco said with a slight smirk. He wrapped his arms around Harry, capturing his mouth in a gentle kiss.

"Her wish?" Harry echoed, dazed from the brief contact. He'd been fantasizing about this all week. Ginny's suspicions had them all on edge, which meant he and Draco hadn't been able to sneak away at all since their encounter after the Great Hall scene had been filmed.

"For another Slytherin," Luna said, materializing at their side. "I think Blaise will be a lovely addition. Think of how beautiful he'll look next to Draco."

She smiled wistfully, picturing the contrast their dark and light skin would make when they were curled up together naked. Harry had no trouble envisioning it, since he'd stumbled across the two of them in the Quidditch locker rooms the two years before. It had been a beautiful sight, but at the time he'd been too shocked at stumbling across his arch enemy in such a vulnerable – and delectable – position.

"Oh yeah," he agreed, laughing when Draco snorted inelegantly.

"I didn't know Neville was gay, though," Harry said, snapping Luna out of her fantasies.

"Oh, he's not," she said, busying herself with setting up the camera. They'd already lost most of the night, and she was anxious to get started. They didn't have classes the next day, but it was a Hogsmeade weekend and she didn't fancy sleeping the rare day of freedom away.

Harry raised an eyebrow at her words, wondering what she knew about his quiet friend that he didn't. Obviously there was quite a bit more to Neville than he'd known, and it made Harry feel like a horrible friend for not making more of an effort with his roommate.

"Not exclusively, at least," she said without looking up from her task. "He and Blaise aren't together together, they're just together at the moment."

Draco shrugged, obviously as mystified by Luna's explanation as Harry was. Deciding that they'd wasted too much of their night already, he dipped his head to kiss Harry again, catching the wizard just as he'd opened his mouth to ask another question. Harry made a gurgling noise as Draco's tongue surprised him, sweeping into his open mouth and teasing his own.

"Ready," Luna said, reclining against a large oak tree to watch the boys kiss. They took no notice of her, which suited her just fine – she didn't want them to stop what they were doing long enough to notice the squid rising out of the water nearby. She'd asked it to shower them with water, since a scene down by the lake would hardly be complete if they weren't soaked to the skin.

Harry tilted his head to deepen the kiss, letting his hands rove up and down Draco's chest and back. He'd just managed to work his way down to the blond's firm arse when a torrent of icy cold water startled them out of their embrace.

Draco looked over at Luna, wide-eyed. She'd left her spot by the tree and was tossing something that looked suspiciously like a large bucket of fish to the nearly transparent squid. Harry collapsed against him, giggling madly when the monstrous thing lifted its pointed beak and let her scratch under what Draco could only assume was its chin, if squids had such a thing.

"Luna," Harry laughed, shaking his head to clear his wet hair out of his eyes. "Luna!"

She turned toward them, her hand still scratching the squid's gelatinous skin.

"Focus. Get that thing to clear out. I can't think about –" he looked at Draco, biting his lip to keep from laughing at petulant expression the sopping wet blond was wearing. "– you know with it watching."

Luna scoffed at his concern but dismissed the Giant Squid anyway, whispering a few words to it before it sank back down into the murky depths of the lake.

"You know?" Draco asked, his lips quirked into a smirk. Apparently Harry's squeamishness had been enough to bring him out of his snit about being unexpectedly soaked. "What exactly is you know?"

Harry blushed, unsure why it was so hard to say the words when he had no problem at all having sex on camera and in front of other people. The Dursleys had been extremely prudish, though, and he still found it hard not to get embarrassed by the explicit words Draco liked him to use.

"I don't think I do know," Draco purred, his fingers warm against Harry's stomach as he began to unbutton his shirt. It was soaked through and sticking to his skin, outlining his nipples, which had pebbled in the cold.

"I think you'll have to tell me –" Draco bent his head, nipping at one of the hard nipples and drawing a groan from Harry. "– exactly –" He pulled the wet shirt off, casting it aside without a second look. "– what it is you mean."

Harry groaned again as Draco dropped to his knees, his hot tongue dancing across Harry's chest, soothing the goose pimples that had formed when the cool night air blew across his wet skin. He sank his fingers into Draco's wet hair, pushing it back from his face so he could see the grey eyes that were looking up at him. He could tell from the glint in them that he wouldn't be getting off easily – Draco meant what he'd said.

Deft fingers moved to Harry's belt, unbuckling it quickly and moving on to the fasteners underneath. Draco paused as he began to ease the zipper down, his teeth scraping against Harry's tender skin as he nipped at the band of Harry's boxers.

Harry angled his hips forward, trying to encourage the blond to continue undressing him. But Draco shook his head, the motion causing the fabric between his teeth to pull against Harry's cock, making him gasp.

"Sex," Harry managed, hoping it would be enough to satisfy Draco. He should have known it wouldn't be – Draco loved to torture him.

"Sex?" Draco asked, pulling away from Harry and releasing his boxers. Harry squirmed, uncomfortably aware of how tight the wet fabric had gotten.

"Penetration?" Harry said hopefully, frowning when Draco simply shook his head. He could hear Luna laughing from behind the camera, reminding him they were being filmed. His face flushed scarlet, but he was too far gone to stop. He hadn't been with Draco all week. "Shagging?"

Draco laughed, a low, rough sound that made Harry's cock twitch with need. Pale fingers lowered the zipper agonizingly slowly, making Harry growl in frustration.

"Fucking," Harry said, biting his lip when Draco peeled the wet cloth away from his erection and rewarded him with a swipe of tongue against hard flesh.

"Bravo," Draco murmured, tugging at the wet trousers and boxers until they pooled around Harry's feet. The dark-haired boy stepped out of them, kicking them to the side along with his shoes. He planted his feet firmly in the grass, his hands braced against Draco's shoulders to keep his balance as the blond swallowed his cock.

"Do you want to fuck me?" Draco asked, backing away and standing. Harry nodded, watching as Draco's creamy flesh was slowly revealed as he peeled his own wet clothes off. His pale skin glowed in the moonlight, his light coloring made even more dramatic by the dark backdrop of the still lake behind them.

Harry nodded, his throat too dry to respond at the sight of Draco wrapping his long fingers around his own cock, stroking himself slowly as he stared at Harry. The dark-haired boy hesitated only a moment before launching himself forward and wrapping himself around the naked Slytherin. Draco leaned his head back, letting Harry suck and bite at his neck. They stumbled backward until they hit tree, the bark rough against Draco's back.

He hissed as the bark scraped the sensitive skin, enjoying the sensation and the fierce determination he saw in Harry's eyes. Pinned between Harry and the tree, he lifted his legs, wrapping them around Harry's waist so their erections could brush against each other.

Draco Summoned his wand, since Harry's arms were busy holding the two of them up. It was an awkward and uncomfortable position, but that just made it more exciting. He cast Lubrication Charms on himself, shivering when the cool sensation flooded his channel, and one on Harry's cock as well. It was all the invitation the Gryffindor needed, and Harry thrust up, lifting Draco a bit as he did so he could enter him.

Draco winced when Harry's weight against him pushed him harder against the tree. He knew he'd have cuts and scratches when they were finished, but he didn't care. He wrapped his legs tighter around Harry's waist, flinging one arm up to help brace himself against the tree as Harry thrust into him again and again. He managed to work his other arm between them, fisting himself as best he could in their precarious position. The friction was enough, though, and soon he was coming, his back arching away from the tree as come splashed across Harry's bare chest.

Harry staggered as more of Draco's weight fell to him to support, nearly falling when his own legs began to tremble with the force of the orgasm Draco's spasms wrung out of him. He managed to push Draco back against the tree, capturing his mouth in a hard kiss as he buried himself deep inside, the aftershocks of Draco's orgasm milking the last of his own out of him.

Luna stepped in front of the camera, her cheeks flushed even in the cool air.

"That was Harry Potter shagging Draco Malfoy against a tree out at the lake," she said, tapping the camera with her wand to turn it off.

Draco let his legs fall to the ground, supporting himself as Harry sagged against him. The scratches he hadn't minded earlier were now stinging, and his entire body ached. He laughed, pushing at Harry so they could move away from the tree. The Gryffindor didn't budge, too comfortable slouched against Draco to move. When even a pinch on the arse failed to get him to move, Draco looked over Harry's shoulder, appealing to Luna for help.

She grinned, bending to pick a long branch up off the ground. She gave it a thoughtful glance, Transfiguring it into something that looked like a thick, slimy noodle. Draco gave her a puzzled look, but understanding dawned as soon as she crept closer, flicking the noodle-like object out like a tentacle. It landed on Harry's bare shoulder, causing the Gryffindor to shriek and jump.

"Gerrof! Get it off of me!" he screamed, dancing around until it fell away, hitting the ground with a sickeningly wet thump.

When he realized it hadn't been the Giant Squid at all but a prank, he tore off after Luna, momentarily unconcerned with his nudity and proximity to the lake. She laughed, dancing out of range by darting closer to the shore, sure Harry wouldn't follow her there for fear of the real squid.

"Get back you here you slag!" he yelled, stopping dead when large ripples marred the surface of the lake. Seconds later two large eyes appeared, making Harry stumble backward lest her prank turn into reality.

Both Luna and Draco watched him struggle into his still-wet clothes, muttering to himself about dangerous squid and unfunny women while he tried to force his legs into his sopping trousers.

"Exaresco," Draco said, waving his wand at Harry's uncooperative clothes. They dried out immediately, and Harry nearly fell when his foot went through the trouser hole without problem. Draco laughed again, casting the same spells at his own clothes before donning them.

Harry glared at both of them, crossing his arms over his now-clad chest.

"Stupid squid," he muttered darkly, glowering at the invertebrate in question.
