Summary: What happens when two sexually frustrated wizards manage to find the Room of Requirement? Presented with plenty of alone time, and the opportunity to experiment, Kurt and Blaine decide to get naughty.

A/N: Okay, so this is a fill for the glee_kink_meme. It's going to be 12 chapters, each chapter taking place in a different month. There will be several different kinks, and there will be a Harry Potter pick up line (not my own) at the beginning of each chapter, and I will try to incorporate it into the chapter. Now, without further ado, I present to you the first chapter of I Solemnly Swear I Am Up To No Good

You look like you'd be a good Quidditch player. Want to ride my broomstick?

The castle practically roared and shook on its foundations as the student body came thundering in, cheering and yelling. For the first time since the legendary Harry Potter had graduated, Gryffindor had won the Quidditch Cup.

And it was all thanks to the best Keeper since Ron Weasley and Oliver Wood.

Sure, Wes Montgomery had made a fantastic catch of the Snitch, and of course Santana Lopez made made many scores. She was known for those off the Quidditch Pitch as well. And yeah, Lauren Zizes and Noah Puckerman were often compared to Fred and George, but they weren't the show stoppers.

No, Blaine Anderson had everyone's attention as he made over fifty spectacular saves, putting his own life at risk many times. He had nearly everyone in the stadium cheering his name madly, rooting for Gryffindor to win the Cup. Even a few Slytherin fangirls had been eyeing the attractive Keeper.

But of course there was always one party pooper. And that one happened to be leaning against a wall, frowning, as his boyfriend was carried by the mass of cheering fans through the castle.

Of course, Kurt Hummel was ecstatic that his House had won, and he was even happier that his boyfriend had made it possible. But that didn't mean that he wasn't miffed. After all, he had been picturing this moment since he started dating Blaine. It had involved him sprinting across the pitch, and kissing his boyfriend passionately, reveling in the victory of his great win.

Of course, he had forgotten a few key details, such as how much he hated running, and how enthusiastic Blaine's teammates were. Sure, he should have expected this, but that really didn't take off the sting of disappointment.

Sighing, Kurt resigned himself to the fact that his plans just weren't going to work out. After all, the Gryffindor Common Room would be packed. If he snuck up to be alone with Blaine, sure the rest of their House would quickly figure out what was going on. No need to scar the First Years after all. Noah Puckerman was known for his crude comments, and his head to mouth filter seemed to be inadequate.

Digging his hands into his pockets, Kurt sighed, and began to trudge along the vacant corridor. He had followed the crowd up to the Seventh Floor, but his feet were too sore to keep up with the rushing crowd.

Suddenly, a pair of arms wrapped around his waist, and Kurt was embarrassed to admit that he let out a loud, undignified squeal. Hearing a deep familiar chuckle behind him, and inhaling the easily recognizable smell of treacle tart, Kurt's eyes widened, and he let out a much quieter, happier squeal, as he turned around in Blaine's arms.

"Blaine!" He cried happily, wrapping his boyfriend in a tight hug. "How did you escape-er, get away?"

Blaine snickered at Kurt's use of verbs. "Well, Puck isn't exactly the most trustworthy guy, and neither is Finn; no offense to your stepbrother. They knocked me against a low rafter, and I sort of somersaulted over their shoulders. I don't think they really noticed. It hurt like a bitch though." He rubbed the back of his head and winced.

Kurt pouted slightly, and pressed a kiss to his boyfriend's cheek. "Aw, I'm sorry mon amour. Do you want me to kiss it and make it better?"

Blaine bit down on his lip, hard. Hearing the French words slip out of Kurt's beautiful lips, in a perfect accent always sent blood flowing straight to his lower half. "I'd like for you to kiss a different part of me." He growled out, his voice low and possessive. And with that, he had pushed Kurt against the wall, prying the countertenor's lips open with his tongue.

Kurt's hands immediately made their way to Blaine's strong, muscular arms that were currently pinning him to the wall behind him. He was kissing back fervently, and loving every second of it. Suddenly, he was glad he hadn't gotten to kiss Blaine in front of the entire school, because in these scarlet skinny jeans that he had worn in support of his team, hiding his obvious erection would have been impossible.

Blaine's hands slid under Kurt's golden jacket, and he smirked. "I'm loving the outfit." He growled, gesturing towards the gold jacket and fedora, with the scarlet jeans that were so tight, he was amazed a toothpick could fit into them. "I've never felt so loved and supported."

Kurt smirked and decided to have a little fun with Blaine. "Oh really?" He whispered throatily in Blaine's ear, taking pride in the shivers that immediately ran down his spine. "You've never felt more loved? How about last week, hmm? When I gave it up to you for the first time? You didn't feel loved, when your huge cock was buried deep inside me?"

Blaine groaned in frustration, and pushed Kurt away. The taller boy was surprised, and slightly hurt. Though that quickly turned into concern, as Blaine literally began pulling his own hair. "God Kurt, you can't just say things like that!" He cried in frustration.

He began pacing back and forth, with his boyfriend watching him carefully. "I mean, all I've been able to think about for the past week was how amazing that felt! But since we live with a pack of wolves who are more gossipy than a group of grandmothers, we'll probably never get the chance to do that again! I just wish there was some way to be alone with you!"

Blaine was ranting now, which Kurt found quite amusing. Until he was distracted by something equally interesting behind his boyfriend. "I mean, we can't do it in an empty corridor, because we'll definitely get caught, and get into loads of trouble, and empty classrooms are just tacky and cliche."

"Blaine?"

"And I mean, we won't get to see each other all summer, since I'm going away to Italy, and even then, my parents would hardly be supportive,"

"Blaine!"

"It's like life is trying to screw with us, saying 'oh here, have an amazing first time, and enjoy it, because you won't ever get a chance to do it again-"

"BLAINE!"

The Quidditch player turned to look at his boyfriend with an annoyed expression on his face. "What?" He cried, slightly irritated that Kurt was clearly not listening to him. But Kurt simply pointed at the wall behind him, and Blaine turned around, expecting to see empty wall. Instead, he saw a large ornate door. Frowning he said, "Um, that wasn't here a minute ago."

Kurt shook his head. "No, it just started to appear when you were ranting about your sexual frustration." Blaine would have blushed, but he was too curious about the door to pay Kurt's words any heed. Biting his lip, he gestured towards the door.

"Let's check it out!" He called eagerly, and Kurt widened his eyes as Blaine immediately grabbed the doorknob. His boyfriend had the habit of acting without thinking, and more often than not, it got him into trouble.

"Are you insane?" Kurt hissed, grabbing his boyfriend's arm. "Do you not remember the bowtruckle incident? I was picking splinters out of your ass for a week!" But instead of halting and blushing like Kurt had expected, Blaine simply smirked cheekily.

"Well, it's a good thing you love my ass then!"

And with that, he turned around, and walked straight into the disappearing, unknown room, without any regard for the warning Kurt had given him. Sighing, Kurt looked to the heavens, with a simple question on his lips.

Why me?

"Holy Merlin." Blaine breathed, and when Kurt examined the room, his jaw dropped. Without trying to sound like he was in a porno film, the room was basically a wet dream. There was a large comfortable bed in the center of the room, with soft fluffy pillows, and silky sheets. Next to the bed was a bookcase, but instead of books, it seemed to hold dozens of bottles of lubes and lotions.

On the right side of the room was a bubbling hot tub, and Kurt felt his muscles sag slightly, just even thinking about it. A little ways away from the bubbling tub was a table, full of…toys. Kurt swallowed, and looked away. Hot damn, they had just had sex for the first time a week ago! Kurt was most definitely not ready for that.

"What is this place?" Blaine breathed in wonder. Well, really he was trying to figure out if it had a lock. Because right now he needed nothing more than to bury his dick in Kurt's tight heat, and this room was really not helping matters.

"This must be the Room of Requirement!" Kurt gasped out, amazed that they had found this place. "It was alluded to in Hogwarts a History: The Revised Edition. You know, by Hermione Granger! I can't believe we found it! So much history has happened in here!"

But Blaine was far more interested in the lock he had found on the door. Quickly bolting it, and placing a lock safe charm on the room, he turned to Kurt, and began kissing his neck. "Mhhm. History. Yeah. Let's make some history of our own right here."

Kurt wasn't buying it. He pushed Blaine away. "Blaaine!" He said, whining slightly. "We can't have sex in here! This is the Room of Requirement! It-It would be like having sex in a secret shrine or something!"

Blaine groaned. "But Kuuurt! I'm so hard! And look, it's called the Room of Requirement. Right now I require to be having sex with you! Please Kurt, I know that you want this just as badly as I do. Come on, please baby."

Kurt bit his lip, and he felt his resolve breaking. He loved when Blaine called him 'baby', and his boyfriend knew it. Suddenly, Blaine began to kiss his neck, biting and sucking. When he reached the sweet spot on Kurt's collarbone, the countertenor moaned.

"Okay, okay! Fine, I'll let you fuck me."

Blaine snorted at Kurt's tone, and his word choice. "Thank you, oh gracious one. Now you, my beautiful boyfriend, are wearing far too many clothes to satisfy me."

Kurt smirked. "And Merlin forbid you go unsatisfied for any length of time." But conceding to Blaine's wishes, he quickly shed the shiny gold jacket, letting it drop to the ground. He didn't even care that it would probably wrinkle. It didn't matter. All that mattered was the fact that Blaine was looking at him so possessively, making his knees turn into jelly.

"Too many clothes yourself sexy." Kurt growled lowly. Blaine smirked, and quickly pulled his scarlet robes off over his head. He was soon down to the pair of black pants he wore under his Quidditch robes, and the white undershirt he always wore.

"Is that better?" Blaine breathed in Kurt's ear, and the countertenor moaned. He quickly tore off his tie, and fumbled with the buttons. As soon as he had the shirt undone, Blaine practically tore it off his shirt, and quickly hoisted Kurt into his arms.

Kurt wrapped his impossibly long legs around Blaine, attacking his mouth fiercely, as Blaine carried him over to the bed. Kurt was tossed unceremoniously onto the bed, but almost immediately Blaine was crawling on top of Kurt.

But Kurt wasn't having any of that. Gripping Blaine's shoulders, he used his strength and momentum to roll over so that he was straddling Blaine's waist. "Hey there." He whispered softly. Blaine smiled, and gripped Kurt's hips tightly.

"Hey yourself. So I hear you landed yourself a boyfriend."

Kurt smirked, and reached down, placing feather light kisses all over Blaine's chest. "Mhhm. That I did. He's pretty sexy you know."

"Yeah?" Blaine asked conversationally, reaching up and tossing Kurt's golden fedora off his head. "I'm jealous."

"Yeah. He's a Quidditch player. He just won this huge match for our House. He's a pretty popular guy. You might know him? Blaine, Blaine Anderson?"

Blaine pretended to think, and slowly, tantalizingly slowly began to finger the button of Kurt's skintight jeans. "I think I've heard of him. I would say that I would send him your way, but I'm a pretty selfish guy you know. I'm not one for sharing."

"Oh, is that right?" Blaine moaned, and bucked his hips up, desperate for some friction. Kurt moaned again, and began scrabbling at Blaine's chest. "Please baby, I need you to touch me. It hurts!" Kurt whined, and Blaine smirked.

"Well we can't have that, now can we?" Slowly, he unzipped Kurt's jeans, and pulled him out of them, letting his boyfriend's cock spring free. Kurt groaned as Blaine's hands lightly brushed against his hard cock.

"Too slow, too slow. I need you to fuck me, and I need you to fuck me now!" Kurt cried out, and Blaine smirked. He quickly stripped himself of his own pants, and pulled down Kurt's boxers. Reaching across, he grabbed the cherry flavored lube, Kurt's favorite flavor.

"I need to stretch you first baby." Blaine said, and Kurt moaned in protest, but that quickly stopped, as soon as Blaine slid a slick finger past Kurt's tight ring of muscle. Kurt immediately gasped, and as soon as he adjusted to the intrusion, he immediately clenched down on Blaine's finger.

Smirking at his beautiful boyfriend, Blaine slid another finger into Kurt, and his boyfriend moaned. "You know, I heard quite a few dirty jokes today. One in particular about Quidditch and broomsticks." Blaine smirked at Kurt, and the countertenor bit his lip.

"Oh yeah? And what was it?" He gasped out, losing his breath. Blaine smirked, and slipped a third finger into Kurt.

"You must be a Quidditch player. Do you want to ride my broomstick?"

Kurt paused, and then burst out into laughter. "Oh my Merlin, Blaine that was absolutely awful!" Blaine however simply laid under Kurt, waiting for Kurt to realize the impact of the question. And as soon as he did, Kurt's eyes widened.

"Y-you really want me to do that?" Kurt asked nervously. Wasn't it a little soon to be doing that? Sure, they had been dating for a year, but they had just had sex for the first time last week. But now that the idea was planted in his head, Kurt wanted nothing more than to ride Blaine.

"Yeah. Yeah, I really, really do Kurt." Swallowing, Kurt nodded happily, and Blaine smeared lube around his hole. Taking a deep breath, Kurt literally impaled himself on Blaine's cock, and both of them gasped at the sensation.

Kurt was breathing heavily, and was taking several moments to adjust. It was one thing having Blaine's fingers in his ass, but his dick was much thicker than anything he had ever had before.

After a few moments, Kurt finally began to move up and down on Blaine's cock, rolling his hips. Blaine moaned, and began thrusting up to meet Kurt's movements. This was hotter than anything they had ever done before. Their first time would always be perfect in their eyes, but this was definitely a whole new level of pleasure that they were experiencing.

Kurt's cock was leaking with precum, and he reached up to stroke himself, as he bounced up and down on Blaine's dick. He moaned, and Blaine thrusted up particularly hard, hitting his prostate. "BLAINE!" Kurt screamed in pleasure.

He felt the familiar heat coiling in his lower body, the tingle at the base of his spine. "Fuck Blaine, I won't last much longer." He moaned, and almost instantly, Blaine reached up and stroked Kurt's cock, hitting his prostate repetitively.

And it was too much for Kurt. He exploded all over his chest, and his muscles clenched around Blaine's hard dick. Feeling the muscle tighten around his cock, encasing it in warm, tight heat. Feeling Kurt orgasm around him was Blaine's undoing. With a shout, he came deep inside of Kurt, and felt his muscles constricting, before relaxing.

Kurt slumped over his body, and slowly slid off Blaine's cock, wincing at the emptiness. He collapsed against the pillows next to Blaine, and sighed. After a few minutes of just lying peacefully, Blaine sat up, arms wrapped around Kurt.

"Come on, let's take a bath." Kurt groaned in protest, but slowly followed Blaine, limping slightly, a result from their previous activities. Blaine helped him into the hot tub, and he let out a breathy sigh of contentment as he slid underneath the hot water. Blaine slid in next to him, and kissed Kurt's forehead lightly.

"I don't want to leave this place." Kurt said mournfully, looking around the amazing room. "It's almost like something from a wet dream." He blushed immediately after saying it, but Blaine smiled, and pushed a lock of his hair back.

"I know what you mean. But hey, we have the whole weekend. Classes don't resume until Monday. And now that we've found this place, who says that we have to 'unfind' it?"

Kurt smirked, and kissed Blaine chastely on the lips. Oh they were going to have fun in here.
