For the most part, Blaine keeps his desire for Kurt in check. He only ever stares at his ass when he’s convinced no one can tell, and even then, only allows himself a few seconds of perving. He knows this can’t go on, so he’s trying to wean himself off even that bit of time. It’s just so difficult, what with Kurt being perfect, and that ass being perfect, good lord.

It all falls to shit pretty quickly, however. Blaine has given the class three weeks to finish the assignment. By the end of two of those weeks, every student has shared their drafts with him and he’s helped them along. All but one: Kurt.

Kurt seems to have realized this, because at the end of class that Friday, he waits behind as the rest of the class leaves, then approaches Blaine’s desk.

“Can you read this?” he asks, thrusting some papers across the desk and into Blaine’s hands. Blaine actually has things to do, but they can wait. He’s been patient enough throughout the past two weeks for Kurt to finally show him some work; there’s no way he’s passing up the chance to finally do so.

“Sure, I’ll look it over right now,” he says, gesturing for Kurt to take a seat. Kurt sits and crosses his legs in that way that makes them go on forever, and Blaine can’t help but stare. Kurt’s skinny jeans are so tight they must be molded to his skin, and his laced up boots are almost knee high. The effect is amazing.

Kurt clears his throat, and smirks as Blaine shakes himself out of it, returning his gaze to the pages in front of him. He reads through the paper, admiring Kurt’s use of language, his distinctive tone, the way he really capture Hamlet’s relationship with Ophelia. He tries not to be biased, seeing as he’s practically obsessed with Kurt, but he has to admit it’s in the top 5 of the class papers.

“This is amazing, Kurt,” he says, smiling up at him. “Truly, you’ve captured the essence of the assignment, and your clear grasp on the play shows. I’m sorry, I don’t have very much criticism to offer you…perhaps talk more about Hamlet’s relationship with his mother? I’ve always found that to be a bit confusing, and very inappropriate considering she's—“

“Yes, I agree,” Kurt cuts him off, smiling softly. “It definitely ties into Hamlet’s feelings of inadequacy when it comes to Ophelia’s rejection, and I've always found his bizarre obsession with his mother's sex life intriguing. I’ll add more in.”

He stands up and reaches over to take his paper back, and Blaine suddenly finds himself really not wanting Kurt to leave. So he does the only practical thing he can think of: he grabs Kurt’s wrist.

Kurt startles, but doesn’t pull away.

“Mr. Anderson?” he asks breathily, clearly thrown off by the professor’s actions. “Are you alright?”

“Yes, I—“ Blaine isn’t sure what he’s feeling, but he knows that if Kurt walks out right now, he’ll never escape this sensation that this moment will be a missed opportunity. “Look, Kurt. I—I don’t really know what I’m doing, or why I’m doing it, but I—I don’t want to freak you out or anything, it’s just—fuck, this is so…”

“It’s okay,” Kurt says with a smile, sliding their hands together. “I like you too.”

Blaine looks up in bewilderment, astonished yet pleased at how simply Kurt is able to say that.

“I am so, so glad to hear you say that,” he says. “I really shouldn't be, we shouldn't be doing this at all but...god, i don't care.  So…where do we go from here?”

Kurt’s smile turns into a smirk, and he drops Blaine’s hand, walking around the desk slowly, emphasizing the sway of his hips. Blaine is mesmerized; he can’t take his eyes off the taller man.

“Where would you like me, professor?” Kurt drawls when he comes to a
stop directly in front of Blaine.  Blaine is surprised and excited by Kurt's initiative, so pleased that he hasn't scared him off, that Kurt wants him. Blaine’s eyes darken and in a flash, he’s grabbed both of Kurt’s hands, spun them both around and pinned the younger man against the chalkboard, their bodies pressed as close together as possible.

“Fuck,” Kurt sighs, immediately pressing their lips together, squirming when Blaine takes over, unable to do more than stand there and take it. Blaine’s tongue swipes across Kurt’s bottom lip, his teeth nibbling for a second before he pushes into Kurt’s mouth, their tongues sliding together, wet and soft and firm, all at the same time.

“Fuuuck,” Kurt moans out as Blaine moves to mouth at his neck, sucking harshly on the skin there and tightening his grip on Kurt’s hands when he tries to pull them loose from Blaine’s hold on them against the chalkboard above Kurt’s head. “God, why haven’t we been doing this since I got here?”

“Because we really shouldn’t be doing this at all,” Blaine answers, thrusting his erection into Kurt’s hip and groaning when Kurt presses back. “Not that I care anymore. As long as we’re careful.”

“Naughty, naughty, Mr. Anderson,” Kurt teases. “Now let’s get the fuck on with it before I die from old age.” Blaine giggles darkly into Kurt’s neck, continuing to suck a hickey there so dark it won’t be gone for weeks.  He wants to own this beautiful boy.

“Patience is a virtue,” he replies, licking up Kurt’s neck to his mouth.

“Fuck virtue,” Kurt gets in before he’s being kissed again. “Or better yet, fuck me,” he says when Blaine finally gives him his mouth back. Blaine’s eyes blow out even more at those words.

“Gladly,” he says, finally releasing Kurt’s hands so that they can both make quick work of their clothing. Blaine’s down to his boxer-briefs when he realizes that all Kurt has managed to remove are his vest, shirt, and undershirt.

“As much as I would love to fuck you with those incredibly sexy boots still on, my dick’s not hard enough to drill through your pants, you know,” he says, rolling his eyes as Kurt actually takes the time to fold his clothes up and place them neatly on Blaine’s chair.

“Some of us actually give a shit about taking care of our clothes,” Kurt retorts, bending down to begin unlacing his boots. Blaine can’t say the view isn’t pleasant, especially when Kurt is obviously putting his ass on display to rile Blaine up even more.

He slowly pulls the first boot off, dropping it next to Blaine’s chair, and bends down again to untie the second one. Blaine doesn’t move his eyes from Kurt’s ass for a second.

When both boots are finally off, as well as Kurt’s socks, Blaine lunges forward and crowds Kurt back against the chalkboard, reaching down to undo his fly. Once the button is open and he’s worked the zipper down, he attempts to pull Kurt’s pants off, only to find that they really must be welded there or something, because they won’t budge.

“Christ, how do you get into these in the morning, with 10 sticks of butter?” Blaine groans. Kurt merely chuckles breathily and smirks as he reaches down to work his pants off, obviously practiced at it, though it does take a few minutes. Blaine’s eyes widen with lust when Kurt kicks them off and he sees that there’s no underwear left on Kurt’s body.

“It’s impossible to wear those comfortably with anything else down there,” he says, not even a drop embarrassed as Blaine stares hungrily at his cock. He does, however, lose control and cry out when Blaine drops to his knees and takes him all the way down his throat so quickly it’s almost unnatural.

“Oh, oh, mm-Mr. Anderson, god, right THERE!” Kurt screams as Blaine sucks him forcefully, pulling back a bit to lave at the apparently very sensitive underside of Kurt’s beautiful dick.

“Call me Blaine,” he says after pulling off to mouth at Kurt’s balls.  he does register in the back of his mind, however, the way his cock twitches at the more formal name Kurt calls him.  He'll have to remember that for later.

“Okay, Blai—BLAINE! YES!” Blaine has taken both of Kurt’s balls into his mouth and is sucking on them intently, never letting either of them drop from his mouth. He decides he really likes making Kurt fall apart, especially when it makes him scream his name like that.

But they have other things to get to. Blaine pulls off of Kurt slowly, letting him drop from his mouth, and stands up quickly before Kurt has the chance to shove his head back down.

“Hey,” Kurt says, pouting. “I was enjoying that.”

“Yeah, well, you’ll enjoy this too. Trust me,” Blaine says, reaching behind him to pull a desk drawer open and retrieve something from it, never breaking eye contact. When his hand reappears, he’s holding a small bottle of lube and a condom.

Kurt glances down between them to see what Blaine’s holding, and he moans and ruts against Blaine’s hip, gripping his shoulders.

“God, yes, please,” he begs, making Blaine whimper and hurry to pull his boxer-briefs down so that they’re both fully naked, placing the condom on the ledge of the chalkboard for later.

“Up,” is all he says against Kurt’s swollen lips, but the younger man seems to understand perfectly, propping himself up slightly against the chalkboard and wrapping his legs around Blaine’s waist.

Kurt starts rutting his cock against Blaine’s, and Blaine allows it as he pours some lube on his fingers and rubs them together to warm it up a bit. Kurt is so busying sliding their cocks together that he doesn’t notice Blaine’s hand moving under him, and only figures it out when a slick finger traces down his crack.

He moans loudly, one obscene, long note as Blaine presses that first finger against his hole, teasing the rim and barely pushing it inside, just rubbing at the entrance. Kurt is shaking in his effort to hold on, his arms wrapped around Blaine’s neck and his legs around his waist.

“Please, more, just fuck me already, please,” he whines, thrusting down on Blaine’s finger but finding no relief as Blaine just moves it down with him, still not pressing any further than the tip of his finger inside Kurt’s hole.

“You’re such a fucking tease.”

Blaine can only chuckle darkly at the comment, considering Kurt is a turned-on, desperate mess in his arms. He finally takes pity on the boy and slides his finger all the way in, quickly pulling it out only to slam it in again, setting a rhythm akin to the one he plans on getting to with his dick.

“Ohhhhhhh, yes,” Kurt moans, gripping Blaine’s neck more tightly, pulling their heads together. He shoves their mouths together when Blaine slips in another finger, groaning into Blaine’s mouth and messily sucking on his tongue.

Blaine thrusts his two fingers in and out of Kurt’s ass a few more times, then presses in hard and crooks them. When he finds Kurt’s prostate, the younger man screams, and Blaine rubs it for a moment before sliding his fingers out and then back in, this time adding a third and very carefully avoiding that spot. He didn’t want Kurt to come before they’d had any real fun, after all.

“God, Blaine, please, I’m ready, just fuck me, now, fuck me please, hard, now, god, please please, Blaine, please.” The older man listened to Kurt’s moans and nearly came himself from the sheer desperation of it.

Goodness was he ever turned on by desperation; the willingness of the partner to do anything, go any lengths, just for release, made him hot like nothing else. He thrusts his fingers a few more times, stretching them apart a bit to really open Kurt up, earning more whines and moans from him, before sliding them out.

Kurt whines from that too, and his ass keeps bouncing down slightly, as if trying to fuck him on air. Blaine has to make himself look away from the wanton boy he’s got pressed against the chalkboard to retrieve the condom. He rips the wrapper open and carefully rolls the condom over himself, hastily covering his cock with lube, and hurrying to line himself up with Kurt’s hole before the other man loses it.

Blaine eases himself in, the tip making Kurt’s hole stretch wide, both men groaning deeply at the feel of it. He presses in slowly, the drag electric. Their foreheads are pressed together and the puff against each other’s lips, both sighing when Blaine is as deep as he can go.

“God you feel amazing,” Kurt breathes against him.

Blaine wants to answer, but Kurt pretty much summed it up for him, so instead of a verbal reply, he pulls his hips back and slams them forward, effectively making Kurt scream once again. Blaine thinks he could listen to the sound of those screams for the rest of his life.

He sets a brutal pace, and neither of them are capable of more than moaning and gripping and sloppily kissing with too much tongue but it’s perfect, it’s hot and sweaty and Kurt’s back is digging into the ledge that runs along the bottom of the chalkboard because Blaine is pressing him so hard into it that it’s as if he’s trying to break through the wall.

Blaine’s fingers clutch firmly at Kurt’s hips, his fingernails digging in so hard that it’ll be a wonder if there aren’t 5 crescent shaped scars on each hip when they’re done. Blaine manages to have a fleeting thought of not being able to wait to see the hand shaped bruises he leaves, deep purple and angry, on Kurt’s pale skin, but then he’s thrusting faster and Kurt’s clenching around him and it’s almost too much, but he’s not ready for it to end yet, so he tries to slow down. It’s a futile effort though, when they’re both so frantic and desperate for release.

Blaine somehow presses Kurt further into the chalkboard and moves his hands down to his ass cheeks, spreading them to stretch Kurt wider and make him tighter around his cock. Kurt’s hands have tangled themselves in Blaine’s hair, pulling and grasping for dear life, unable to do anything but hang on for the ride as Blaine actually manages to fuck him harder.

“God, Blaine, I’m close,” Kurt pants out, the syllables choppy and half-moaned.

“Yes, yes, come, come for me, Kurt, come all over me,” Blaine says, gritting his teeth as he fucks harder, faster, nearly breaking them both in half. He pulls one hand away from Kurt’s cheeks and brings it down in between them, taking Kurt’s cock in his hand and stroking tightly, massaging his thumb over the head.

That’s all it takes, and Kurt is coming hard, screaming out Blaine’s name and clenching down so hard on his dick that it’s a wonder Blaine is still thrusting. But he is, and he fucks Kurt through his orgasm, and then keeps fucking until he feels that tight, hot coil in his lower abdomen, and shoves all the way in, relishing the way Kurt’s hole is still tightening a bit in the aftershocks of his orgasm, and he comes, harder than he ever has before.

They’re both wrecked; they sag against each other, Kurt’s legs loosening their death grip around Blaine’s hips, his fingers working their way out of Blaine’s hair, Blaine easing his cock out of Kurt’s hole, still soliciting a gasp from both of them at the sensation. Kurt lowers his legs and manages to stand on his own, albeit shakily. His arms twine around Blaine’s neck again, and Blaine’s hands find their way back to Kurt’s hips, putting slight pressure on the bruises he formed by gripping them as they fucked.

Kurt sighs and presses their lips together; it’s hot and dirty and sweet and gentle all at once.

“I think maybe I need to lie down,” he says, and Blaine laughs deeply and genuinely, stepping away from Kurt to allow the younger man to pry himself off the chalkboard, rubbing at the sharp indent along his lower back from the ledge. “Shit, that’s going to hurt for a while.”

“I don’t think that’s the only thing that’s going to hurt,” Blaine says cheekily, tracing Kurt’s bruised hips and pressing a hand against one of his ass cheeks. Kurt swats playfully at it, lacing their fingers together and pulling Blaine down to the floor. They lie there together, coming down from their incredible highs, legs tangled and skin soft and warm against each other. Blaine isn’t sure how long they’re on the floor for—he just knows that he could stay there forever.

Kurt apparently has other ideas. He lets go of Blaine’s hand and disentangles his legs, stretching out his body—which causes Blaine to drool a bit—and pushing himself up to his feet. Blaine finds himself staring up at
Kurt’s renewed erection, and he sits up on his elbows, giving the now smirking man a questioning and horny look.

“This is a nice desk you’ve got here, professor,” Kurt practically purrs, walking around Blaine to trail his fingers along the edge of the desk. The younger man smirks down at Blaine, his intentions twinkling behind his eyes, sparking something low in Blaine’s stomach. “What do you say we put it to good use?”
