“Excuse me, Mr. Hummel?”

Kurt turned around, his back pressing against the cold, slick white-board.

A few inches away, Blaine Anderson stood dangerously close, his head cocked to the side, eyes wide and innocent.

“I think I missed a few notes during the lecture today. Could you help me catch up?”

Clearing his throat, Kurt tried to side-step and escape, but Blaine's hands were resting on either side of his shoulders against the board.

“I can't help you unless you let me get to my desk, Blaine,” Kurt tilted his head down, raising his eyebrows.

“Actually, Mr. Hummel,” Blaine stressed his name, letting his mouth linger on the words, “I didn't miss any notes. I was really wondering if I could help you.”

Kurt remained silent, his eyes narrowing.

“You don't have a wedding ring on your finger, Mr. Hummel. And all of those nights grading papers, you probably don't have time to go out, or even have time for yourself. You must be tense,” Blaine hissed into Kurt's ear.

The rush of wind sent a shiver down Kurt's spine, making its way down to his cock, which twitched slightly in response.

Blaine dropped his head in time to see the movement.

He laughed, a silent eruption of his shoulders, “If that's all it took, you must really need some relief. I can provide that for you, sir. If you let me.”

Kurt looked at Blaine, hesitant, while Blaine's hands moved from beside his shoulders to grasping his hips, tugging their bodies close and creating a delicate friction.

A quick breath escaped Kurt's lips, his breathing coming in short, ragged bursts.

“You're so hot, Mr. Hummel. Every day in class, you turn your back to write on the board and all I can do is stare at your ass. Wanna take a handful of it,” Blaine's voice was low, breathy, hot in Kurt's ear, their crotches moving together as Blaine kept a steady pace, “And your skin tight jeans leave very little to the imagination.”

Blaine moved his hands to the front of Kurt's jeans, fingers ghosting over the outline of his cock and then hastily undoing the button and zipper, pushing down his pants and briefs in one clean swipe, knees hitting the floor with a soft thud.

“Shit,” Kurt whispered, raking his fingers through his student's tightly gelled hair.

Taking Kurt's cock in his hand, Blaine pushed the head into his mouth, licking over the slit and then taking it out of his mouth, inspecting it.

“Blaine,” Kurt said, becoming impatient.

“Yes, Mr. Hummel?” Blaine asked, wide eyed, cock still in his grip.

Kurt moaned, the sight and the look of it overwhelming. His head fell back against the board as he pushed his hips forward, wanting to feel the tight, wet heat inside of Blaine's mouth.

Obviously taking the hint, Blaine licked up the underside of Kurt's cock, swirling his tongue over the head before taking the whole thing in his mouth and pushing his head back and forth.

A few minutes of sloppy, slick noises, moaning, and thrusting later, Kurt was gasping for air, barely able to warn Blaine before he was coming. Blaine stuck out his tongue in time to catch some of it, but most of it landed on the floor between them.

After pulling up his pants, Kurt tugged Blaine up, turning them around so Blaine was pinned to the board. A broad smirk playing on his lips, “Now it's my turn,” Kurt breathed, fingers dancing over the fabric of Blaine's ass.

But Blaine's face turned red, his eyes dropping down, Kurt's eyes following.

A large, wet stain covered a spot near Blaine's hip.

Kurt palmed over it, “Teenagers,” he shook his head, giggling.

“It's a little embarrassing,” Blaine admitted, locking his arms around Kurt's shoulders, “But well worth it.”

“Still cocky, hm?” Kurt rolled his eyes, “Even after you came in your pants?”

Face turning red again, Blaine bit his lower lip.

Kurt ducked his head, meeting Blaine's lips with his own, wet and plump and tasting of himself.

“This was fun, Blaine,” Kurt broke away from Blaine's grip, walking over to his desk and gathering his things, “But I need to get home. Papers to grade.”

Blaine's smile didn't quite reach his eyes, “Right. I-I'll see you in class Mr. Hummel.”

Kurt walked over to Blaine, planting a quick, sloppy kiss on his lips and whispering almost inaudibly, “I'll need to talk to you tomorrow after class.”

With a wink and a nod, Kurt walked out of the class, swaying his hips and thinking of tricks he could pull for tomorrow's lesson with Blaine.
