See disclaimer in Chapter 1. I don't own 'em.

Chapter warnings for slash, group sex and exhibitionism. The pairing is … well … hard to describe. All of the guys we've initiated so far. For Christi, Ms. Marauder-Cullen and Kevin Johnson, who all wanted to see the greenhouses. (Hope you don't mind I expanded the pairing, KJ!)

"I can't tonight, Gin," Seamus said, smiling apologetically at the red-haired witch.

"I already told Lavender and Michael that we'd be there!" she protested, her eyes flashing with anger.

"Well, you should have asked me first. I have other plans," he said, side-stepping her to continue on toward the boy's dorms.

Ever since they'd shared a few kisses she'd seemed to think she had some sort of ownership over him, and it had only gotten worse after the Gryffindor/Slytherin game. She'd come back to the dorm in a huff over Harry being dismissive and latched onto him instead, planting herself in his lap for most of the evening and teasing him to distraction. He knew it was Harry she really wanted, but he didn't feel too bad about leading her on himself, since he also knew she couldn't have Harry. Seamus was beginning to see the wisdom in Harry's objection to letting Gin into their little group – she was too possessive by half, and from what he could tell she was a complete innocent, no matter what stories Michael Corner and Zach Smith told about her.

"Seamus," she whined, thrusting out her lower lip in exactly the way Lavender and Parvati had told her guys liked.

"Ginny," he mocked, exasperated. Getting into her pants wasn't worth this effort. Harry would have to find another way to get her to leave them alone, because he wasn't about to put up with her being a nagging fishwife if they weren't even shagging.

She followed him up the stairs, making him wish the boy's dorms were spelled against the opposite sex the same way the girl's were. She stuck behind him as he pushed open the door to his room, making a nearly naked Ron cry out in protest.

"It's nothing I haven't seen before, Ronald," she snapped when he shrieked and pulled the bedclothes off his mattress to cover himself.

Harry snorted, drawing her attention to him. He'd just stepped out of the bathroom, naked but for a towel slung around his waist. Dean narrowed his eyes at the way not only Ginny, but Seamus and Neville, all turned to look at him.

"Out, Gin," Harry said, pointing toward the door. Her freckled cheeks flushed, and she looked from Harry to Seamus, who had crossed to his own bed to start stripping down for the shower.

"Seamus," she started, but he shook his head, cutting her off.

"Not interested, Gin. Sorry."

She huffed in indignation, angry tears brightening her eyes.

"Harry, tonight –"

"I have plans, Gin. Sorry," Harry said, shrugging into a lightweight jumper but keeping the towel firmly around his waist.

She looked like she was about to stomp her foot in frustration, but she restrained herself, swirling on her heel and storming out the door, slamming it loudly behind her as she left.

"About fucking time," Seamus murmured, rolling his eyes. "She's worse than a succubus."

Ron colored, feeling the need to defend her even though she'd embarrassed him.

"She's my sister!" he yelled, winging a comb in Seamus' direction.

"Yeah, your sister the succubus," Seamus taunted, kicking the door to the bathroom closed behind him so whatever Ron threw next would bounce off.

The grounds were dark when Draco and Pansy made their way outside. There was no need to skulk, since seventh-years were allowed out after dark as long as they were back in their dorms by curfew, so they strolled out toward the rose garden arm in arm, looking just like the other couples out looking for a secluded place to snog.

Pansy laughed when she saw Lavender Brown practically devouring Michael Corner's face near the fountain. Neither of them would be getting an invitation to their little club, going from the way they seemed to value enthusiasm over skill.

Draco pulled her across the lawn, winding a path toward the darkened greenhouses. Blaise had left almost an hour ago, taking a more circuitous path there with the help of Harry's mysterious map. As they got closer to the greenhouses, he could make out two shapes pressed up against a storage shed, a dark-haired boy wrapped around a girl with long, blonde locks. He grinned, wolf whistling as he and Pansy drew closer. Harry looked up, sneering at the Slytherins before shouting something derogatory and going back to snogging Luna.

Ginny was seething with fury from her spot in the bushes near the shed. She'd followed Harry out of the common room, shocked when he met up with the Ravenclaw in the entryway and headed outside after a quick snog that had proven he was very familiar with her body.

She hadn't noticed Seamus and Hermione sneak out of the portrait behind her under Harry's invisibility cloak. They were leaning up against the same shed Harry and Luna were at the moment, whispering updates about who had made it to the greenhouses already to the couple. Neville had been there for the longest, since he had the password and the best excuse to be there. He'd told Professor Sprout that several of the Fanged Geraniums were in need of a good flossing, and she'd been more than happy to assign him the task, since it was tedious and disgusting.

As soon as Draco and Pansy disappeared from sight, Harry pushed off the wall of the shed, wrapping an arm around Luna's shoulders and guiding her back up toward the castle. Ginny followed, almost screaming in frustration when she rounded a corner and found no sign of them. She trudged to the nearest entrance to the castle, a dark look on her face.

"Jesus she's annoying," Harry muttered as soon as she'd gone inside, pulling the cloak off. He and Seamus were pressed against the wall, with Luna in front of them. Seamus had taken Hermione to the greenhouses before returning to rescue them.

"I say we Confund her," Seamus said, slipping back under the cloak as the three set back off toward the greenhouses. A lone couple wouldn't be noticed, but three people would likely draw attention, something they definitely didn't want.

"Blibbering Humdingers are very protective of their own," Luna said serenely to the empty space beside them, making Seamus curse and Harry laugh.

"She means Ginny has older brothers who would hex your bollocks off if you tried. They're not all as obtuse as Ron, you know."

"So we're just here to watch?" Pansy asked, wrinkling her nose in disappointment. She jumped when a small Devil's Snare reached out toward her, retreating toward the center of the aisle.

"It will be hot," Hermione said, bumping Pansy with her hip. She'd suggested tonight's activity, something she'd heard about from her old friends who'd attended public school.

"But I don't like cocks," she whined, yelping when Draco snaked a hand up her skirt and pinched her arse.

"But darling, that's not what you say when –"

"Sod off," she laughed, pushing him away as he made obscene noises and gestures.

"Ready," Luna called from the more open space of the classroom. Pansy and Hermione retreated further back into the plant nursery to watch off camera, while the five naked boys formed a circle on-screen.

"No one's left handed?" Blaise asked suddenly, as if the thought had just occurred to him.

Everyone shook their heads, several of them laughing at how uncomfortable the situation was. It was a bit cool in the greenhouse, and Neville shivered a bit. Beside him Blaise ran a warm hand up his hip, making him smile.

"Should we just go, or do we need to count down and say –"

"Oh, for Merlin's sake," Draco said with a snort, stepping forward in the circle to get closer to Harry. He cut the other boy's question off abruptly by wrapping his hand around Harry's half-hard cock.

The dark-haired boy let out a choked laugh, rolling his eyes at the Slytherin but reaching out and doing the same to Blaise, who was standing next to him. The darker boy's cock was thicker but shorter than Draco's, and Harry curved his fingers around it, enjoying the heavy weight of it against his palm.

Blaise grinned, letting his hand wander across Neville's hip until his knuckles brushed up against his now-fully hard cock. He rubbed his thumb against the slit in the way he knew Neville loved, chuckling when the Gryffindor moaned softly.

Neville turned and grinned at Seamus, who was watching everyone else wide-eyed. The Irishman groaned when Neville's callused palm closed around him, stroking him to full hardness within seconds. He closed his eyes, tilting his pelvis toward Neville while reaching out to take Draco's cock in his own hand, tugging at it with the long, sure strokes he knew the blond liked.

"Fuck this is hot," Blaise murmured, his breathing ragged as Harry quickened his strokes. He'd been skeptical when Hermione had proposed it, but there was something about watching the others that made it much more erotic than he'd imagined.

"Somebody start the spell," Draco panted, a fine sheen of sweat covering his face and chest as he tried to concentrate both on the sensation of Seamus' hand moving over his shaft and what he was doing to Harry.

"Concateno," Harry murmured, tightening his grip on Blaise's cock.

"Concateno," Blaise said, his fingers locked around Neville's length.

"Concateno," Neville breathed, letting his fingers brush against Seamus' balls as he stroked.

"Concateno," Seamus cast, sliding his thumb over the head of Draco's cock.

"Concateno," Draco finished, gasping when the magic surged through the completed circle.

Suddenly it felt like there were five hands on his cock, stroking and pulling him toward orgasm. He groaned, his hand moving faster against Harry's shaft in response.

"Oh God," Harry groaned, biting his lip as his pleasure intensified. He could feel his orgasm building in his belly, but he knew the spell would hold his release captive until everyone was ready.

"Jesus, Jesus, Jesus," Seamus panted over and over again, his eyes tightly shut again to block out any extra stimulation. The feeling was like nothing he'd ever experienced before.

Neville pressed his tongue against his teeth, holding back cries of pleasure. His knees were shaking with the effort of standing under such an onslaught of pleasure, and he was kept upright only by the sheer power of the linking spell, which wouldn't allow them to break ranks until completion.

Blaise could feel Neville's muscles trembling, and he gave the base of his cock a tight squeeze, hoping to help him regain some control. He heard Neville grunt, and Blaise looked over at him, surprised to see the Gryffindor staring back at him. Some of his own tight control slipped at seeing the pure need in Neville's gaze, and Blaise leaned over before he could stop himself, kissing Neville hard.

They could all feel the magic swirl around them, building them toward climax. After only a few more strokes Blaise felt something change in the air around them, and suddenly he was groaning into Neville's mouth, wave after wave of pleasure cascading over him as he came. Neville's lips were locked against his almost painfully as the other boy rode out his own orgasm, his gasps and whimpers only making Blaise more aroused.

Seamus screamed, his fingers tightening almost painfully around Draco's cock as his own mind-numbing orgasm overtook him, infused with the pleasure the other four felt, the pleasure overload making him shudder as he spurted hot come over Neville's hand.

Draco struggled to keep his eyes open, watching Blaise and Neville kiss as though their lives depended on it. He flicked his wrist as he stroked Harry's cock, knowing it would extend the other boy's already heightened orgasm. Harry hissed something unintelligible in Parseltongue, his chest heaving as he came. He opened his eyes long enough to wink at Draco, knowing full well how much the blond liked to hear him speak in Parseltongue. His gaze flicked down to Draco's cock, watching pearly come spurt over Seamus' freckled hand as Draco convulsed.

"Jesus, God," Seamus swore when the spell finally released them. The circle of sweaty, sticky, panting boys took a few stumbled steps back as the magical link disappeared, leaving them all a bit disoriented and weak.

"Seamus Finnigan, Draco Malfoy, Harry Potter, Blaise Zabini and Neville Longbottom in a linked circle jerk in Greenhouse number three," Luna said as she danced in front of the camera, her cheeks flushed from watching the boys. "Cut."

She wandered over to Pansy and Hermione, unsurprised to find both girls looking rather rumpled.

"Good idea, Hermione," she said approvingly, waggling her eyebrows as she jerked her head back toward the still-dazed group of boys, her radish earrings bobbing at the motion.
