It started out innocently enough. Blaine was searching for something on his computer, and Kurt, bored, walked into his room and decided to dramatically drop into his lap.

Smiling, Blaine had pulled him closer, kissing his cheek. Kurt returned that kiss with one on the lips. The kiss had been gentle enough at first, and then slowly progressed, becoming deeper, hotter, and more intense. He couldn't help it. Kurt was wearing one of those kilts of his - that he could only get away with on the weekend – and Kurt knew they turned him on like nothing else.

Tongues delved into each other’s mouths and both of them took turns moaning against each other’s lips. They had making out down to a science now. Blaine tugged on Kurt’s leg, until his boyfriend shifted, moving so that he was now straddling Blaine’s lap. His legs slid down through the arms of the computer chair, and Kurt used them for leverage.

He began rocking against Blaine gently, and Blaine’s hands automatically went to Kurt’s hips. That's when Blaine realized Kurt wasn't wearing any underwear. Their lips were fused together. Blaine needed to touch Kurt’s skin – his hands drifted to the edge of Kurt’s shirt, and tugged it up over Kurt’s head. They broke apart, gasping, as Blaine freed him from the fabric, and tossed it across the room with a flick of his wrist. Kurt let out a pained noise.

“Blaine, that's silk-” Blaine covered Kurt’s mouth with his own, cutting off Kurt’s words. Kurt responded, the shirt forgotten as Blaine explored Kurt’s chest with his hands. He mouthed his way across Kurt’s jaw, down along his neckline, pressing kissing into the delicate skin.

He wanted to suck the tender flesh into his mouth, nibble it with his teeth, but he didn’t. Blaine had learned the hard way that hickey’s were a no-no with Kurt – the boy had bitched a blue streak the last time Blaine had done it – so Blaine kept going, leaning Kurt backward a little so he could take Kurt’s nipple into his mouth.

Kurt moaned breathlessly, right in his ear, and Blaine shuddered. They were both hard now, Blaine could feel Kurt’s cock pressing into his, and was sure Kurt could feel his as well.

They’d only done this a few times and never anywhere but a bed, so there was a thrill of excitement in the air at trying something different. Kurt went to work on the buttons of Blaine’s shirt while he kissed his way across Kurt’s chest - purposefully leaving marks there, as those areas had been deemed ‘okay’ – to find Kurt’s other nipple and pay attention to it as well.

His shirt was finally off and then Kurt was touching him. Blaine loved the way Kurt’s fingers felt on his skin, so very soft. Hands began fumbling with belts and buttons, and Kurt got off Blaine’s lap for just a moment, long enough for Blaine to slide his pants off. and for Kurt to grab the small bottle of lube and a condom from where Blaine kept them in his bedside table. He started to take his kilt off, but Blaine put a hand on his arm.
“Leave it on.” Something flashed in Kurt's eyes, and he nodded slowly. Time was off the essence now, as Blaine caught sight of the clock on his desk. His roommate would be back within the hour and Blaine did not want a repeat of two weeks ago – regardless of how daring he and Kurt decided to be, exhibitionists they weren’t.

Blaine fumbled with the chair settings for a second, lowering it to the floor, and then tilting the back so he was slightly reclined. He crooked his finger at Kurt, who’d been staring at him with hungry eyes. Kurt moved like a flash, repositioning himself across Blaine’s lap, and the two of them were face to face now. Blaine opened the lube, and spread some over his fingers before pulling Kurt down for a kiss.

He waited until Kurt lost in the kiss, unconsciously grinding against him before moving his hand back, under the fabric of Kurt's kilt and sliding a finger inside. Kurt froze for second breaking the kiss with a hiss and a groan.

“Let me in,” Blaine whispered against his lips, and Kurt relaxed just enough for Blaine to push his finger the rest of the way inside. Blaine moved his finger, in and out until Kurt was panting, making sure to occasionally brush against his prostate. Kurt jerked and cried out every time he did it, and Blaine couldn’t help the pride that surged through him.

He spent a few more minutes opening Kurt up, working in a second and finally a third finger, until Kurt was trembling.

“Ready?” Blaine asked, pulling his fingers out. Kurt nodded, unable to speak. He made quick work of putting on the condom and slicking himself with lube, which Kurt watched. Blaine slid down in the chair a little and then Kurt was sinking slowly down on his cock. Blaine’s eyes rolled up into his head, the feeling of Kurt surrounding him almost too much to bear. He damn near came right then.

Kurt moved slowly at first, testing out the new position, seeing what felt good. He finally figured out what seemed to work for them both, his hands on the arms of the chair, using them to guide the force of his movements.

Blaine didn’t think it could get better than this. He was so deep inside Kurt, and every time Kurt sank down, he lost the ability to breathe. Kurt was making all of these little noises, his eyes closed, his head titled back. Blaine had never seen him look more beautiful than right then.

Suddenly this slow and steady pace that Kurt had set wasn't enough. He needed more. In one smooth motion – how he pulled it off, he had no idea – he stood up, lifting Kurt with him (Kurt cried out in surprise), and lay Kurt on his desk. It didn't matter that every, his carefully labeled folders, utensils and other school supplies went crashing to the floor. He slammed into Kurt, driving as deep and as hard as could, and Kurt let out a shriek.

Waves of pleasure crashed over him suddenly, his orgasm shocking him, and he cried out. Kurt clenched around his cock, milking him for all he was worth. Kurt went to work on himself, stroking his hard length, and he came across his own chest after a moment.

Blaine kissed him, a little sloppily after the mind blowing orgasm he’d just had. He pulled out of Kurt, taking off the condom and tying it off before wrapping it in a napkin. He’d throw it away in the boy’s bathroom later.

Kurt got up on shaky legs and found a towel, using it to wipe both of them off.

Blaine tugged Kurt close for a kiss.

“You're going to make me ruin all of my clothes, aren't you?” Kurt asked, pulling back and gesturing to his stained kilt.

“That's the plan,” Blaine murmured. “Then you'll just have to go around naked.”

Kurt snorted and kissed him again.
