Blaine’s eyes darken and he’s on his feet again in no time, arms twining around Kurt’s waist and mouth sucking and nibbling the tender skin under
his ear. Kurt moans and squirms out of Blaine’s grasp.

“Hey, wha—that is the opposite of what I want you to be doing. Where are you going?” Blaine whines as Kurt moves away from him, rounding over to the other side of the desk.

“I want you,” he says sultrily, pointing a finger at Blaine and crooking it to pull him closer by some invisible force. “To get on the desk,” he continues, sweeping a hand, palm up, over the desk, arching one perfectly plucked eyebrow and causing Blaine’s breath to hitch. “And spread yourself out for me, Mister Anderson,” Kurt finishes, drawing every word out.

Blaine seems frozen for a moment, his eyes wide and his cock trying to harden rapidly, and then he’s scrambling to comply, jumping up on the desk and crawling, honest to god on his hands and knees, to the other side of it where Kurt stands, sliding down onto his butt and laying back, his legs hanging over the edge.

“God, yeah, just like that,” Kurt moans, breathing heavily at the sight of Blaine displaying himself on the desk. He settles between Blaine’s spread out legs, grabbing his ankles when the professor tries to wrap his legs around Kurt’s waist.

“Kurt,” he groans, thrusting up, trying to get friction on his aching dick. But Kurt is having none of it. He leans over Blaine’s body, arms twisting awkwardly as he makes sure he kept a firm hold on Blaine’s ankles, forcing them to stay apart, and starts licking his way down Blaine’s chest, purposefully avoiding his nipples and only slightly dipping into his belly button when he reaches it.

“Nnngh, Kurt, please.” Blaine is writhing on the desk, his legs pulling desperately to be released but unable to break out of Kurt’s grip, his hands clutching either side of the desk, knuckles white, the veins in his throat and temple standing out from the tension of straining his neck so much.

Kurt continues making his way down Blaine’s body, pulling his legs up so that they’re level with Kurt’s mouth to kiss and nip at the inside of Blaine’s thighs, causing the older man to squirm and cry out. Suddenly, Kurt drops Blaine’s ankles and slides to the floor, tugging Blaine’s hips closer to the edge of the desk so that his ass hangs off of it. Before Blaine can bend his neck far enough to see what Kurt is doing, he feels wide, wet licks over his hole, and screams out in ecstasy.

Blaine throws his head back, barely even registering the pain as it slams against the desk. Kurt works his tongue over his hole, up and down his crack, teasing his perineum and pressing at his rim with the flattest part of his tongue. Blaine fists his hands in his hair, only to quickly re-instate their grip on the edges of the desk to steady himself when Kurt pulls his hips, shoving his ass further into his face, slowly pressing his rigid tongue into Blaine’s hole.

Once he’s worked it in, he doesn’t thrust. He just holds it there, and Blaine starts to go crazy from not enough pressure, the just there pleasure that could be so much more….but Kurt isn’t moving.

“God, Kurt, please, please, why aren’t you doing anything, god, please, I’ll do anything, just move, please, lick me, god, anything, just do something, I’m going to explode, oh, my god, this is so unfair, please, please, please.” Blaine can feel Kurt’s smile in his ass (and isn’t that hot), can tell he’s smirking at the way Blaine is shamelessly begging, but he can’t help it. Kurt is teasing him so good, and as much as he loves it, he just needs more. Kurt pulls out and looks up at him and Blaine wants to cry.

“Look at you,” Kurt says with a smirk. “Moaning and begging for it…all open and willing and desperate for me to eat you out. You have no idea how sexy it is to watch you fall apart.”

Suddenly, Kurt dives back down and shoves his tongue back in, and he’s finally, finally moving, and Blaine almost wishes he hadn’t gone back down there, because he’s fucking his tongue into him hard and hot, and Blaine can’t take it, it’s too much, it feels too good, and he’s grabbing Kurt’s head and pushing his face as far into his ass as he can, and he’s coming untouched, streaking across his stomach, Kurt’s tongue fucking him through it and then continuing to lick at his oversensitive skin as he comes down slowly.

It takes him a few minutes to come back to reality, and when he does, he realizes that Kurt’s head is gone from between his legs and one of Kurt’s soft hands is pressing harshly against his mouth. Blaine furrows his brows in confusion and looks around the room, trying to see what Kurt is seeing….but there’s nothing there.

“Mmmph?” Blaine tries to ask, and Kurt finally looks back down at him, cautiously removing his hand and then pouncing on Blaine, straddling his hips and grabbing both his wrists to pull them over his head harshly, the desk creaking under their combined weight.

“You idiot. What, are you trying to get us caught?” Kurt hisses, leaning down to attack Blaine’s lips with his own, leaving Blaine breathless, his lips puffy and shiny.

“Wha—“ Blaine clears his throat, his voice having gone gravelly and low.
“What are you on about?”

“You were screaming, Blaine. Full out shouting as you came, and I don’t know about you, but I’d rather not have anyone come running in here, thinking you’re being murdered or something only to find—what?

"What’s so funny?” Kurt huffs. Blaine has started giggling uncontrollably, and Kurt presses down on his wrists hard until he stops long enough to talk again.

“M’sorry, I’m not laughing at you, it’s just…my room is soundproof,” Blaine says with a wolfish grin.

“Sound…proof?” Kurt raises an eyebrow.

“It’s not like that…it wasn’t even my idea. I do a lot of activities with my classes that tend to be loud, I guess, and the other teachers in the building were complaining that we were distracting, so they all pitched in, along with the college, to soundproof my room. Now, I don’t have to change my teaching methods, and we don’t bother anyone. So don’t worry, no one heard me, no one thinks I’m being murdered, and no one is going to walk in on us.”

“Blaine?” Kurt asks, leaning down low to whisper right against his lips.

“Mmhm?” Blaine answers, closing his eyes and smiling softly at the feel of Kurt’s breath against his mouth.

“Did you lock the door?”

“Shit.” Blaine scrambles to get up, only to be shoved back down by Kurt’s hips on his and his strong arms still gripping his wrists.

“Ah, ah, ah, you’re not going anywhere. Tell me where the keys are, and I’ll go lock it.” Blaine barely registers the request, seeing as Kurt has started grinding his hard cock against Blaine’s spent one, but manages to grunt out that the keys are in the second drawer on the left side of the desk. He whines pathetically when Kurt gets off of him, but enjoys the view of Kurt’s hips and ass as he walks casually to the door, most definitely swinging his hips on purpose. Then Blaine gets a wonderful eyeful of Kurt’s dick as Kurt makes his way back after locking the door, taking his time, pumping his hand over his cock as he moves through the rows of desks back to the front of the room.

“See something you like?” Kurt says, smirking at the way Blaine licks his lips and never takes his eyes off Kurt’s hand on his dick. “Pass me the lube.”

Blaine finally tears his gaze away to comply, handing Kurt the lube and spreading his legs again when Kurt moves back in between them.

“Look at you…so slutty for it,” Kurt says, although his eyes are a little unsure. Blaine just moans deeply and spreads his legs further, pushing his ass forward when Kurt’s hands grab at his cheeks. “Yeah?” Kurt asks.

“Yeah,” Blaine breathes out, thrusting his hips up and desperately searching Kurt’s eyes.

“Jesus, I can’t believe you’re into that. It’s like someone picked you out of my fantasies and dropped you into my life as a ridiculously sexy present, or something.”

Blaine just moans again and presses his ass against Kurt’s hands, spreading his legs as far as he can.

“Slut,” Kurt says, testing it out, and it makes Blaine groan, deep and loud, arching up further and practically screaming when Kurt slips the first finger in, quickly adding a second seeing as he’s already a little loose from their earlier activities.  The oversensitivity is just this side of too much, and Blaine loves it.

“What a pretty slut, spreading yourself out, offering yourself to me like this,” Kurt says, and his voice is still a little hesitant, as if he’s not quite confident that he’s saying the right things, so Blaine half sits up and grabs at Kurt’s head, gripping the back of his neck and bringing him into a sloppy kiss, wet and messy, both of them moaning into it and eventually Blaine screaming into it when Kurt adds a third finger and crooks his fingers up, causing white hot pleasure to spread across Blaine’s body.

Blaine drops back down with an “oomph”, letting Kurt continue to open him up, the whispers of “what a good little slut” he is making him even hotter and helping him along to a third erection, although he still feels overly sensitive and tender. He reaches down to pump himself a few times, only to have Kurt pull his fingers out of his slick hole and swat his hand away.

Kurt at some point had gotten another condom and is currently rolling it onto himself, Blaine still moaning and squirming. Kurt positions himself at Blaine’s hole, Blaine’s moans escalating as he pushes inside, both of them gasping at the slow drag and the pressure of Kurt’s cock. He starts off slow, pressing in and pulling out, Blaine squirming as he can feel Kurt against every part of him, and he’s big and he feels so good, and he’s fucking him so sweetly, as if he just wants to crawl inside and never leave. Blaine feels quite the same way, and the feeling only grows when Kurt picks up the pace, still fucking him slowly but much harder, each thrust practically stabbing his prostate.

Then Kurt quickens pace, and thrusts even harder, and Blaine howls as he feels his orgasm approaching, more painful than pleasurable, and he comes, almost completely dry, his body going into spasms and his cock twitching as it goes soft. Kurt is still fucking him, and he literally can’t take it, it hurts too good, but he’s unable to speak, he can’t form the words to get Kurt to stop, and he feels like crying.

Kurt thrusts faster and harder, only slightly aware of Blaine’s struggle and trying to bring himself to climax as quickly as he can, yet also semi-striving on the torture he’s inflicting.

Finally, he takes pity on Blaine, and pumps a few more times before thrusting all the way in, as deep as he can go, as close as he can get, and comes hard, his moans loud enough that they sort of echo around the room.

He pulls out of Blaine, and the older man winces at the feeling, wanting to get up and stretch out his limbs but completely incapable of movement.

Kurt seems to notice, and, still panting and shaking slightly from his orgasm, helps Blaine down from the desk, an arm around his shoulders for support as he brings them both down to the floor to lean against the desk.

"Pretty convenient that you just so happen to have condoms and lube in your desk, Mr. Anderson," Kurt says sometimes accusingly.  Blaine just laughs at his inquiry, too well-fucked to tell if he seriously wants to know.

Kurt puts his head on Blaine’s shoulder, which is still trembling along with his entire body from how intense his last orgasm had been. Blaine laces their fingers together and nudges his shoulder against Kurt’s head, getting him to look up at Blaine’s face.

“What?” Kurt says self-consciously, the corners of his lips tugging up as he looks at Blaine from underneath his eyelashes.

“I am so glad,” Blaine whispers, then pauses to lean down and kiss Kurt full and sweet on the lips. “That you signed up for my class, Kurt Hummel.”

“Why professor,” Kurt says, giggling when Blaine picks up their linked hands and starts kissing Kurt’s knuckles. “I couldn’t agree more.”
