"There's no way she'd go along with it," Harry hissed, keeping his voice low so the students around him wouldn't hear.

Harry and Draco were seated side-by-side in Professor Binns' class, arguing about the next chapter of their journal.

"Luna wants help, and that's who she wants," Draco said, his voice not quite as low as Harry's.

Seamus shot them a dirty look; their conversation had awakened him from his daily History of Magic nap. Draco raised an eyebrow at Harry, nodding toward the Irishman.

"Merlin, Draco, no!"

"Why not?" he pouted, leaning closer to whisper in Harry's ear. "He would be a lot of fun. He could be our History of Magic classroom conquest."

"No," Harry said, crossing his arms over his chest.

Their conversation was starting to draw attention. Most ignored them, figuring it was just Potter and Malfoy fighting like usual, since their whispers had carried an edgy tone, and Harry's eyes were narrowed dangerously.

"Fine," Draco hissed, sitting back in his chair. He picked up his quill, pretending to take notes.

Just ask her.

Harry looked down at the parchment that Draco had slipped in front of him, rolling his eyes.

No. If Luna wants her help, she can ask her.

Draco pursed his lips, muttering something under his breath.

She's your friend. If anyone should be the one to ask her about this, it should be you.

Draco waited a beat, frowning slightly when he realized Harry wasn't going to answer him.

Maybe we shouldn't tell her at all. Just ask her to meet us and let her 'discover' us that way.

Harry gripped his quill angrily, the strokes so hard they almost broke through the parchment.

I don't see why you're so eager.

Draco grinned, sending a side-long glance at Harry.

Awww. Is ickle Harry a widdle bit jealous?

Harry's eyes narrowed to slits, and he grabbed Draco's arm, pulling him in close.

"No!" he whispered, his eyes blazing.

Lavender leaned forward, poking Harry in the ribs.

"What's going on between you and Malfoy?" she asked, raising a perfectly plucked eyebrow.

"Nothing," Harry ground out, his teeth clenched.

"We're having a bit of a disagreement about Granger," Draco drawled, his gaze fanning lazily over Lavender and Hermione, who was seated next to her.

"What? What about me?" Hermione asked, leaning forward toward Harry.

Harry closed his eyes and sighed. Damn you, Draco, he thought.

"I'll tell you after class, Hermione," he said, turning back around to focus on the ghost at the front of the classroom droning on about the Great Goblin Rebellion. "I just need to ask you to meet up with me later."

***

"You want me to meet you and Malfoy in the library after dinner tonight?" Hermione asked, her brow furrowed.

Hermione's confusion only grew when she saw the blush begin to form on Harry's cheeks. He looked away, swallowing hard before he nodded. He was too nervous to eat, but he pushed bits of the Shepherd's Pie around his plate anyway.

Things just weren't adding up for Hermione, and she hated being out of the loop. This was the first time she'd talked to Harry in – well, in a while. She'd been busy with Head Girl duties, and Harry hadn't been around the common room much.

"Why are we meeting with Malfoy? What's going on between you two? Have you two been fighting? Are you in some sort of trouble?"

Harry brought his gaze back to Hermione, the blush still staining his cheeks.

"No, nothing like that. Just meet us there tonight," he said, thrusting something silky into her hands.

Hermione looked down, startled to see Harry's Invisibility Cloak.

"What – Harry – when you said –"

"Tonight, as in after the library has closed," he said, his voice low as he leaned closer so no one else in the Great Hall could hear him. Ron sat on Hermione's other side, oblivious. "We'll be there just after Madam Pince closes up at 11. The door will be open, so you won't technically be breaking any rules."

Hermione's eyes narrowed, but she quickly stuffed the silvery material into her bag, shielding the motion from the Gryffindor table with her body.

"When I get there, you're going to tell me what's going on, Harry," she said, her voice thick with censure and warning.

Harry's blush darkened even more, adding to Hermione's suspicions. He cleared his throat, shooting a quick glance over at the Slytherin table where Malfoy was currently holding court.

"Er, yeah," he said, his gaze flicking to Hermione and back to the blond. "You'll know exactly what's going on; trust me."

***

Luna had staked out the library, so she was able to dart in to set up the camera as soon as Madam Pince retired for the night. The library was not spelled against trespassers, and a simple Alohomora opened the thick wooden doors easily. Harry and Draco weren't more than a few minutes behind her, easing into the silent room as quietly as possible. Once inside, they set about getting ready.

***

Hermione crept into the library, flinching as the ancient wooden doors creaked softly when she pushed them open. She closed them behind her carefully, sure that whatever Harry was up to should probably stay secret. The cloak rustled around her, but she didn't take it off. She wanted to see if Harry and Malfoy were already here.

She followed a faint noise coming from the recesses of the cavernous room, heading toward the student study tables that lined the back wall. She quickened her pace as the noises became discernable; someone was moaning. Drawing her wand, Hermione looked down to make sure the cloak still covered her feet as she approached. From the sound of it, Harry and Malfoy were fighting. Why did they need her here for that?

She rounded the corner of the stacks, her hand gripping the fabric of the cloak, ready to pull it off so they would see her arrival. The biting reproach she'd readied died on her lips as she took in the sight in front of her, the cloak slowly sliding off her still body, still clutched in her fingers.

Hermione's eyes dilated at the delectable sight in front of her, all concerns about Harry's safety forgotten. Luna had set the camera rolling a few minutes earlier, and Draco and Harry were already well into their lovemaking.

Hermione tilted her head, watching in fascination as Draco's dexterous tongue traced patterns across Harry's naked chest and abs, her pulse quickening along with Harry's. She sighed and shivered when Draco drew a small brown nipple into his mouth, her own nipples tingling as well. Definitely not fighting, then, Hermione thought, her mind nearly blank.

Behind the camera, Luna grinned. She'd known this would be a great idea! Hogwarts' most well-known bookworm, watching Harry and Draco defile her beloved library. Her blonde head peeked around the bulky camera, which was on its tripod, when she heard Harry moan.

Draco had finished laving his chest and abdomen, moving on to his erection. Hot breath ghosted against the sensitive skin as Draco hovered just centimeters above Harry's throbbing cock, a wicked grin on his face as he watched Harry strain under him, bucking up to force contact with the blond's mouth.

After hesitating another second, Draco acquiesced, opening his mouth and nearly swallowing Harry whole in one smooth motion. A gasp from Harry had Draco's own cock twitching in anticipation of what was to come.

Draco pulled back, drawing a moan of protest from the dark-haired boy underneath him.

"Shh," Draco said, bringing a slender finger to his lips. He smirked at the way Harry's eyes went dark at the sight, knowing the Gryffindor was remembering where those lips had been just seconds before. "This is the library, Potter. Have some respect."

Draco bent his head, outlining Harry's lower lip with his tongue before delving inside his mouth. Harry moaned quietly again, leaning into the scorching kiss, his own tongue moving to stroke Draco's. Hermione made a quiet sound, shifting so she could see more of the action.

Both Draco and Harry looked in her direction, and Hermione's eyes widened as she realized she'd been caught watching. Her lips parted to deliver some excuse, but no words would pass through her dry throat. Likewise, her traitorous feet were rooted to the spot, no matter how much she wanted to turn and run, her mortification making her face burn.

Harry held a hand out toward her, motioning for her to come closer. Draco sat back on his heels, a delicious smirk on his face.

After a moment's hesitation, Hermione shuffled forward, shakily walking toward the naked boys, who were sitting on top of one of the study tables. When she was close enough, Harry grasped her hand, pulling her over until she was nearly level with them. Draco smiled at her, meeting her bewildered eyes, before lowering his head to kiss his way down Harry's throat.

"You wanted to know what was going on between me and Malfoy," Harry said, his voice low and husky. "Welcome to your front row seat."

"I – you said – I was just – I didn't – and then – are you – " Hermione stuttered, unable to form a single coherent thought.

"We brought you here for a purpose, Granger," Draco said, his voice slightly muffled against Harry's golden skin. "Sit down and enjoy it."

Hermione had never been so embarrassed – and so turned on – in her entire life. She slid into a chair they had set aside for her at the table. Her new position put their naked bodies at eye level, and she squirmed in her seat, her body heating uncomfortably at the sight. She knew she should leave, but she couldn't convince herself to look away from the sight in front of her.

"No talking," Draco reprimanded, giving her a heated look. "This is the library, after all."

Hermione's lips clamped shut, her gaze riveted on the naked boys in front of her. Neither of their erections had flagged in the least during the exchange; both enjoyed having an audience. Draco shot Hermione a wink, bending his head to return to his task. Full lips parted, and Hermione watched Harry's thick cock disappear between them. Her eyes widened comically as Draco fumbled for a small pot that had been placed on the table, dipping his fingers inside to coat them with viscous lube. She gasped as the slender fingers trailed their way to Harry's entrance, circling his hole before gently plunging in. Harry arched up off the desk, his eyes tightly closed. He began to whimper, trying to thrust down on Draco's fingers and up into his mouth at the same time.

She watched as Draco expertly sucked Harry off, stroking, squeezing and licking until both Gryffindors were panting slightly, and Harry was near release. Draco gave his balls a tug, bringing him back from the brink of orgasm.

"Do you think she can handle it?" he whispered, his lips against the shell of Harry's ear.

Harry's green eyes flicked over to Hermione, who was still sitting in the chair, her eyes glazed and her face slack with shock and lust. He watched her for several seconds, smiling when her eyes met his.

"Mmm," Harry said, "I suppose we'll find out."

With no more notice than that, he flipped their positions. He kissed the tip of Draco's nose, then lowered himself so he was hovering directly over Draco's cock. Draco dipped his fingers in the small pot again, this time coating his erection. He positioned his cock at Harry's entrance, his body tensing as the Gryffindor began to lower himself slowly down its length.

"Oh sweet mother of Merlin," Draco gasped, his muscles shaking with the effort of holding himself still while Harry slid down his cock with agonizing slowness.

"Oh my God," Hermione whispered, her eyes as wide as saucers as she watched the scene in front of her.

"Oh Merlin yes," Harry grunted, allowing his body to adjust to the intrusion before sliding further down, gasping at the sensation of fullness once Draco was fully seated inside him.

Luna just watched from the shadows, her hand over her mouth, stifling the urge to laugh. The sight of staid Hermione watching Harry Potter and Draco Malfoy fuck was beyond the pale, and Luna was enjoying herself immensely.

***

"Harry Potter and Draco Malfoy have sex in the library, Hermione Granger watches," Luna said from her spot in front of the camera, nodding solemnly. "Cut."

Harry was beginning to feel self-conscious, suddenly aware that he was naked, and Hermione was still staring at him with a befuddled, albeit dreamy, expression. He Summoned his clothes, hastily throwing his denims on as he hopped down from the table.

"So, Hermione, er – " Harry looked around the room wildly, trying to find something other than Hermione's face to look at as he spoke.

"We've already been here an hour, Harry," Draco said, pulling his jumper over his head. "Let's not risk staying any longer."

Luna nodded, packing up the camera. She crossed over to Hermione, tugging the Gryffindor out of her chair and leading her toward the doors.

"Room of Requirement, then?" she asked, still amused that Hermione had apparently been shocked senseless.

"You two take the cloak. We'll meet you there," Harry said as he tied his trainers.

***

"I think you should start from the beginning, Harry," Luna said helpfully, patting Hermione on the knee. The two were perched on an over-stuffed couch in the middle of the room.

"We're kind of making a book," he said, his eyes transfixed on a loose thread in the carpet. Since this is the Room of Requirement, did it give me the string to focus on because it knew I needed it? he wondered absently, still not meeting Hermione's eye. "About sex."

"A book about sex," Hermione repeated flatly, her gaze shifting from the now red-faced Harry to Luna, then finally to Draco, who sat in the corner.

"Not really about sex, per se," Luna chimed in, gesturing with her hands. "It's a book that features people having sex around the castle. In photos."

"In photos," Hermione repeated, her voice still incredulous.

"In a nutshell, yes," Luna said, smiling sweetly.

"And you thought the library was an appropriate place to have sex?" Hermione asked, her voice rising.

"No, of course not," Luna said patiently, a smile in her blue eyes. "That was the point entirely."

Harry was suddenly grateful Draco had thought to move their discussion here, to the Room of Requirement. The last thing he needed was Madam Pince or some other professor rushing in, which surely would have happened had they stayed in the library.

"And you told me to meet you there so I could watch?" Hermione asked, incredulous.

"It was my idea," Luna said, smiling serenely. "Your reaction was just perfect. And it was fun, wasn't it?"

Hermione shook her head as though trying to clear it, attempting to wrap her brain around the fact that she had just been filmed watching her best friend have sex with Draco Malfoy.

"You and Malfoy are together, then?" Hermione asked, knowing it was a ridiculous question.

"Um, well. Yes, I suppose," Harry stuttered, looking up when Draco began to clap.

"Eloquent. Very eloquent. You're just lucky I love you for your body, not your mind," he said, rolling his eyes.

Harry huffed out a sigh, straightening his shoulders and looking a dumbstruck Hermione in the eye.

"Yes, Hermione, I quite enjoy being buggered by Draco Malfoy," he said clearly, his tone mocking. "I also enjoy buggering him. Are you happy now, Draco?"

Hermione looked from Harry to Draco, her thoughts conflicted. On one hand, Harry was having sex with Malfoy. On the other hand, Harry was having sex with Malfoy! The memory of the two beautiful boys together made her mouth water.

"Wait," she said, her sharp gaze turning to Draco. "What do you mean you love Harry?"

Draco rolled his eyes, looking away.

"What it sounds like, I suppose," he said, clearly put out that Hermione was forcing this information out of him.

"Oh, snuggybuns, I had no idea you cared so," Harry said, making kissy noises at the blond across the room. "I love you too, Drakie-poo."

"Sod off," Draco spat, his tone lacking venom . A goofy grin stole across his face as he looked at Harry, who was still making kissy faces from the sofa, and he added, "my cuddly-wuddly Har-bear."

Harry's cheeks pinked, and he grimaced at the endearment.

"Yes, Hermione," he said, his voice serious again, "Draco and I are dating. We've been dating since July."

She studied Harry carefully, noticing how his lips curved sweetly when he looked across the room at Draco. She suppressed a sigh at the sight, her eyes glazing over slightly as she thought about seeing more of the two of them together.

"And you want me to help you three make this book? You want me to engage in sexual activity with you," she said, her gaze lingering on Harry and Draco before she turned to Luna, blushing. "All of you, all over the castle, recording it to boot, breaking I don't even know how many Hogwarts rules?"

"Pretty much, yeah," Harry said, his cheeks darkening again.

Hermione quirked her lips, pretending to consider the offer. In truth, she'd been on board the second she'd understood what they were asking. After all, she was the smartest girl at Hogwarts. It would be idiotic to pass up an opportunity to see the two hottest guys at Hogwarts having sex, especially if she got to be involved. She could have walked away at any point during their earlier show, but she hadn't.

"Which rooms have you already done?" she asked, leaning in to read the parchment Luna was jotting down plans on. "Because I have a wicked idea for the Potions Lab … "
