The next day in class, Blaine's Calculus teacher leaves the room for a minute. The entire class takes it as a cue to bring out their phones, and Blaine is no exception.

He grins to himself and taps out a message to Kurt.

Your ass looks really hot in those blue pants. I just want to grab it.

He knows Kurt has study hall right now. He knows Kurt will get the message, and he tries to imagine the look on his face... it Kurt would blush, if he'd he pleased.

Blaine had plenty of time to think the night before. He and Kurt have only been dating for a couple of months, but their relationship had been decidedly PG-rated. Somehow in Blaine's mind Kurt had slipped into a place that was almost untouchable. Kisses were fine, and Blaine's imagination didn't hesitate to go there but his hands stayed above the equator, each perfect layer of clothing in place.

Maybe it's because Blaine doesn't really have much experience either, except for his jerk off fantasies, but he'd thought maybe after Karofsky, Kurt just... wouldn't want to.

But Kurt is a teenage boy, too, and Kurt had definitely been hard. It makes Blaine shiver in class and shift, trying to quell the arousal making him harden. It doesn't help when his phone buzzes though, caught between his hands to dull the sound.

Why didn't you?

Blaine's eyes flit toward the door but the teacher isn't back.

Maybe I will. After glee? They have glee at 3:15, just after their last class.

Make it 2:45. Get a sick pass.

Why Kurt, are you encouraging me to lie... what about my quality education. Blaine's grinning so hard he's getting strange looks from his classmates.

He can just hear Kurt's next reply, as if Kurt were saying it right to him.

I know you did the reading at Dalton already and I can tell Mrs. Jacobs I have an advisor meeting. She never checks. Storage closet by teachers lounge.

Blaine's teacher comes back at the worst possible moment, just as Blaine is about to reply. He snaps his phone shut and tries his best not to think about what Kurt could possibly want to get up to in a janitors closet.

Blaine slips into the janitors closet and finds Kurt already there, organizing the paperclip boxes by size. He clears his throat, because Kurt doesn't seem to hear him.

Kurt jumps about a mile, spinning around. His hand flies to his mouth and he laughs in shock when he sees Blaine. "You're early."

"No, I'm not." Blaine grins, amused and nervous at the same time - but not nearly as nervous as Kurt looks. Somehow it makes him feel better, more in control... less like he's making an idiot out of himself.

Kurt doesn't make a move toward Blaine, so Blaine takes the first step.

Then the second.

"So," he says, with about a foot of space between them. "You were kind of bold earlier in that text message."

Kurt's laugh is high pitched. Blaine knows it as Kurt's oh-god-what-do-I-say laugh.

"Hey," Blaine says, voice gentling. "It was hot."

Kurt's eyes brighten - that impossible blue.

"C'mere," Blaine says. "Kiss me."

Kurt steps forward obediently and their mouths meet, warm and wet and searching. He doesn't even notice Blaine's hands creeping down until they cup Kurt's ass and then isqueezing/i.

Kurt jumps again and Blaine snickers into the kiss. "I'm sorry, I couldn't help it."

"You cad!" Kurt swats at Blaine's arm, but he's laughing, too. "I'm sorry. I feel ridiculous."

"Don't. I meant it. It was hot. You are... so hot." Blaine steps back, letting his eyes sweep over Kurt, blatantly appreciative in a way he doesn't usually let show.

"You are the first person in my life that has ever made me feel that. Last night-"

"If last night was the first time I've made you feel that, then I am definitely failing at my job of boyfriend."

Kurt's fingers curl into the material of Blaine's shirt and he reels him back in for another kiss. Blaine lets Kurt control it and heat explodes in his gut when Kurt turns and presses Blaine against the wall, sturdy supply shelf. The edge of something digs into Blaine's back but he wouldn't dream of interrupting this to complain, to move, to even breathe. Kurt's tongue is inside Blaine's mouth and Kurt's body is pressed against his, tall and lean and warm and perfect, and even with two months of jerking off almost every day thinking about Kurt doing things like this Blaine had vastly underestimated how much of a turn on it would be. The feeling multiplies tenfold when Kurt's hips jerk forward and Blaine can feel the hardness pressing against hip. A groan catches in his throat, muffled against Kurt's mouth, and Blaine thrusts back. He's on uncharted ground here, following instinct, and instinct leads him to press a thigh between Kurt's legs. They move together, coordination fumbling and jerky, but eking out insane amounts of pleasure from the rutting.

Until Kurt's phone rings.

He pulls back, hand flying to his pocket to tug out his phone. "H-" He has to stop and clear his throat. "Hello?"

Blaine barely registers a word Kurt is saying because he's too busy staring at the outline of Kurt's cock. His mouth is watering just looking at it - the first real look he's seen at it, and the fact that Kurt is still wearing pants doesn't matter one bit with how tight they are.

He reaches out and palms it without thinking, because Kurt is still close enough. Kurt lets out a strangle noise that sounds like he wants to say Blaine's name but cuts himself off just in time.

Blaine jerks his hand back, realizing that's the sort of thing he might consider too far. Kurt manages to get out an apology to Mercedes and ends the call. "Christ, Blaine, you can't just-"

Blaine's stomach drops. "I'm so sorry, Kurt, I wasn't thinking-"

Kurt seems to realize how his words are coming off. "No, I didn't mean - you ican/I do that, just not while I'm on the phone!"

"I can?" That seems to be the only part of the statement that reaches Blaine's ears. He grins and Kurt blushes harder. "Mercedes? Oh - shit. We're late, aren't we?"

"Yep," Kurt confirms, nodding. "She thought it was, uh... strange that we were both late. She thought maybe some of the football guys were giving us trouble."

"Oh, that's good. I mean - that's a good excuse."

"Right, like she's going to buy that after I almost had an orgasm over the phone." Kurt rolls his eyes. He leans back into Blaine like he just doesn't want to leave. Blaine doesn't try anything else funny - they do need to get to the music room, and in presentable form.

But before he steps away so they can both pull back he can't resist adding, "Orgasm over the phone? Maybe that's what we should try later..."

Kurt groans in a way that sounds absolutely... tempted.
