A/N: Continuing with the prom theme from last chapter... But smutty this time! This is what happens in my brain when I watch Darren perform "I'm Not Gonna Teach Your Boyfriend How to Dance With You."

Microphone

The music started and Blaine spun around, his deliciously full lips parted in an "O" as he jammed to the first few notes of the song. The performance had barely begun and he already looked like he was having the time of his life. That was something Kurt had always loved about Blaine - he was a fantastic performer, not only because of his incredible talent but also because he always seemed to have so much fun. His energy was contagious. Kurt smiled and danced in time with the music, feeling very proud that it was his boyfriend who was up there rocking the house and making everybody swoon.

And then - oh. Oh God. Oh God.

Blaine was running his hand down the mike stand in an absolutely vulgar way. There was really no other word to describe it. His hand flexed as it skimmed down the stand, practically fucking caressing it, and then his fingers closed around the metal about halfway down. Seconds later, that same hand was wrapped around the microphone itself, holding it sideways in a grip that Kurt imagined was probably very firm, applying just the right amount of pressure without being too tight...

Oh sweet Jesus. Had no one else noticed how blatantly sexual that was? Was no one else now thinking about other, microphone-shaped things Blaine's hand had been wrapped around recently? Like yesterday in the backseat of his car? Or three days ago on the couch in Kurt's bedroom?

Fuck.

Mercifully, Blaine had stopped rubbing the mike stand, but now he was bopping around and dancing in a way that was so very Blaine, and Kurt found himself completely transfixed (not for the first time) by the way his boyfriend's body moved. There was such a natural ease about him, a subtle confidence that manifested itself in his slightly quirky dance moves. His knees and feet turned inward slightly and one leg was bouncing up and down with the beat and it shouldn't have been sexy but it really, really was. Especially because Kurt could just make out the definition of his muscular thighs through the material of his perfectly fitted pants.

Fuck. How was it possible for those pants to fit Blaine so well? And why, why was he wearing them in public?

Kurt was vaguely aware of a commotion that seemed to involve Finn and Jesse taking place on the other side of the gym, but now Blaine was making "ah, ah" noises that sounded far too similar to other noises Kurt had heard him make, and he was finding it difficult to focus on anyone but Blaine. Blaine, who was looking like an absolute superstar and flashing that trademark smile that Kurt loved so much. Blaine, who had to be the sexiest person on the fucking PLANET and who really needed to get off the stage now and do something about the ache that was developing in Kurt's groin.

Finally, the song came to an end and Blaine's body bent forward as he dropped to his knees. His fucking knees. And Kurt's imagination was in overdrive again, because there were very few things that he enjoyed more than Blaine on his knees. And fuck, now he had a fucking full-fledged boner in the middle of prom and that was mortifying and Blaine was going to have to fix it immediately because it was all his fault anyway. Stupid sexy bastard.

Blaine hopped off the stage and was instantly mobbed by a group of admiring girls. He's all mine, bitches, Kurt thought smugly as he caught Blaine's eye and jerked his head towards the door. With a last, smoldering look, he turned on his heel and exited the gym, hoping that Blaine would take the hint and follow. He did (thank God), appearing in the hallway two minutes later, still looking flushed and happy from his performance.

"What's up?" he said curiously.

Kurt responded by grabbing Blaine's tie, pulling him forward, and sliding his tongue into Blaine's mouth. "This," he breathed, rubbing his erection against Blaine's hip, "is what's up."

"Oh God," Blaine said, his eyes fluttering closed as his own cock stirred in response.

"You are so. Fucking. Sexy. When you perform," Kurt murmured, all hot breath in Blaine's ear. His tongue darted out to lightly lick the shell.

Blaine moaned, leaning into Kurt as his knees weakened slightly. "Kurt. We can't do this here."

"Of course not," Kurt said, looking affronted at the thought. He grabbed Blaine's hand and tugged him down the hallway into the darkened Glee Club classroom. Blaine followed like an eager puppy, and the moment the door was shut behind them, he found himself flattened against a wall, Kurt's body pressed tightly against his.

"I need you to take care of this," Kurt hissed, rolling his hips in a way that left no question as to what the "this" was that he was referring to. "Now." He sucked Blaine's lower lip into his mouth and bit down lightly, as if to further emphasize the urgency of his demand.

Blaine whimpered and nodded, thrusting back against Kurt. They both gasped at the delicious friction of their covered erections rubbing together. "What do you want?" Blaine breathed. "My hand?" He pressed the heel of his hand against Kurt's bulge, and Kurt bucked in response. "Or my mouth?" He dragged his tongue up the length of Kurt's elegant neck.

"Your hand," Kurt whined, thinking of how Blaine's hand had gripped the microphone. He wanted to feel that grip around him, feel the warmth and strength that he had come to associate so closely with Blaine.

"As you wish," Blaine replied, palming Kurt more roughly through the material of his kilt. He flipped them around so that Kurt's back was against the wall, then slid his hand beneath the kilt and tugged Kurt's leggings down over his slender hips, fingers grazing appreciatively over the smooth skin of his lower abdomen. Wrapping a firm hand around Kurt's cock, he began to stroke with practiced movements.

Kurt arched into his touch, his head falling back against the wall as he thrust into Blaine's talented hand. "This was all I could think about," Kurt choked out. "Watching you perform. Holding that microphone - ohhh," he moaned as Blaine's thumb passed over the head of his dick.

"Such a dirty mind," Blaine said with a laugh, making Kurt shudder when he reached back to fondle his balls.

Kurt could feel the tension building in his body, and Blaine's strokes were coming faster now, his hand twisting slightly as it traveled up and down Kurt's length. There was so much heat and friction and it was all too much and then he realized - "Fuck, Blaine," he cried. "I can't - my kilt -"

But Blaine was already one step ahead of him, sinking to his knees (fuck, his knees) and taking Kurt in his mouth just as Kurt's entire body spasmed and he came, his shout echoing in the darkness of the empty classroom. Jesus, his boyfriend was perfect.

Blaine sucked Kurt gently until his body relaxed, then re-adjusted Kurt's leggings and pressed a hand against his own now-painful erection. He had barely had a moment to enjoy the relief when Kurt's hands closed around the lapels of his jacket and dragged him back to a standing position. "Now," Kurt said, kissing him hotly, "what do you want?"

"Anything," Blaine pleaded, reaching between them to palm himself again. Actually, he knew exactly what he wanted - that pretty mouth of yours on my dick, right now, please please please - but they were fairly new to all of this, and for some reason, he still felt guilty asking Kurt to do that for him.

"How about this?" Kurt whispered in Blaine's ear, and oh sweet, merciful God, he was sliding down Blaine's body and kneeling on the floor before him. Kurt ran his fingernails up Blaine's legs, remembering how they had looked on stage, then deftly unbuttoned and unzipped his pants. Untucking Blaine's dress shirt, he rucked it up a bit and and leaned forward to kiss Blaine's stomach, tongue running playfully along the skin just above his boxers. Blaine whined.

Kurt yanked Blaine's pants down and mouthed his arousal through the thin cotton of his boxers as Blaine placed his hands against the wall behind Kurt, bracing himself. His breath was coming in short, shallow gasps now, and Kurt was still playing with him, groping his ass and rubbing his nose along Blaine's erection. "You love this, don't you Blaine?" Kurt breathed, inching Blaine's boxers down. "My mouth on you."

Oh holy mother of fuck.

"Nghh," was all he could manage in response.

Kurt seemed to take this as a yes, and pulled Blaine free of his boxers. He licked the head of Blaine's dick, then blew on it lightly, laughing as Blaine let out a strangled moan of desperation. "Kurt," he begged.

Kurt wrapped his lips around Blaine, sinking his mouth down as far as he could go. His tongue swirled and licked, his cheeks hollowing out as he sucked harder. How was he already so damn good at this? Blaine was struggling to remain on his feet and doing all he could to keep from fucking Kurt's mouth.

Kurt pulled his mouth off of Blaine and began tonguing his balls, gradually licking his way up the entire length of Blaine's cock. Blaine's entire body was twitching now, because the room was too dark to see and all he could do was feel and everything was wet and hot and Kurt. His palms were sweaty against the wall and Kurt's fingers were dragging down his thighs and for some reason it suddenly hit him that he was getting a fucking blow job from his boyfriend in an empty classroom right in the middle of junior prom. And then he convulsed and swore and came into Kurt's hot, waiting mouth.

He probably would have collapsed right there had it not been for Kurt, who stood up and supported him with one arm as his other hand zipped Blaine back into his pants. Sagging forward against his boyfriend's body, Blaine sighed happily and pressed a sweet kiss to the side of Kurt's neck.

"You alright there, champ?" Kurt said, clearly pleased with himself.

"Mmm," Blaine hummed. "I can't believe we just did that."

"Yeah, well, it's not my fault that you look like you're making love to the mike stand when you perform."

"And it's not my fault that you're clearly just a sex-crazed maniac. Not that I'm complaining."

"If you had heard the noises you were making just a few minutes ago, you might rethink who you're calling a sex-crazed maniac."

Blaine chuckled. "Well, at least we're sex-crazed maniacs together."

A/N: I think I went a bit overboard on the italics in this one. Oops. Also, I just want to say that I actually think this scene is slightly OOC... In my mind at least, they wouldn't have gone this far sexually by the prom episode. But the idea came to me and I just had to write it, so yeah. Hope you liked it! OH AND if you are one of those wonderful, wonderful people who read the first chapter of my story Never Never Land, I am planning on continuing with it, it's just taking a little longer than expected. Okay, that's all. :)
