Things were suddenly becoming problematic.

Well, just day time, really.

At night, when Blaine's dick was in his hand or vice versa, life was pretty much great.

But it's the nights that begin to make the days so difficult.

See, Kurt can't keep his eyes to himself now. He can't stop staring at Blaine during French. He can't stop watching the way his fingers curl around his pen. His eyes are glued to that almost imperceptible red mark on Blaine's neck, just barely visible above his collar. Kurt had left that mark there in the wee hours of the morning and he can't stop staring. And with the visuals come the memories, the way Blaine arches his back, the way Blaine's fingertips feel on his skin, the way Blaine occasionally cries out when he comes.

None of these thoughts are particularly helpful during the day time when he can't do anything about it.

They're sitting in the dining hall across from each other amidst a bunch of the Warblers and Kurt's got his eyes locked on Blaine's fingers as he attempts to swirl pasta around on a fork.

How can something like that even be remotely sexy?

Blaine pauses in the action and looks up, catching Kurt's eyes.

Blushing immediately, Kurt's gaze darts away. He suddenly finds the salad on his plate very interesting.

When he glances back up, he expects to see Blaine with a secretly knowing grin on his face.

However, he does not.

Blaine's mouth is drawn in a tight line and his eyebrows are scrunched together just a tiny bit.

He doesn't look Kurt in the eye for the rest of the day. Even during Warblers' rehearsal, he doesn't address Kurt at all.

Kurt…doesn't know what he did wrong.

After practice, they walk back to their dorm room together in silence. Once inside, Blaine drops his bag on the floor and leans heavily against his bed.

"We need to talk."

Kurt freezes.

This doesn't sound good at all.

"Can you – can you sit?" Blaine asks, gesturing across from him to Kurt's bed.

Kurt nods slowly, setting his schoolbag down next to his desk, and seats himself on his bed. He folds his hands together in his lap.

"What's wrong?" Kurt finally wonders aloud.

He sees Blaine's throat work as he swallows.

"I don't…think we should do this anymore."

"…Do what?" Kurt questions, hoping that Blaine doesn't mean what he thinks he means.

"This whole friends with benefits thing," Blaine clarifies.

"Don't call it that."

"Whatever you want to call it. I don't think we should do it."

"But – but why?" Kurt asks weakly. He didn't see this coming at all. Things have been fine. Where was this coming from?

"I just…don't think it's working out."

"I don't understand," Kurt admits.

Blaine finally lifts his head to meet Kurt's eyes for the first time since lunch.

"I see the way you look at me," Blaine tells him. "I see you staring and I…I can't handle it."

"I'm not-"

"I get that you don't – I can see why – ugh, I don't even know how to say it."

"Just say it."

"It's obvious that you've developed feelings for me."

"What?"

"I can tell, Kurt. You're starting to feel…more. And that was part of the deal, you know? That that doesn't happen. So I think we should end it."

Kurt's heart pounds rapidly in his chest. But that wasn't…that's not why he looks at Blaine. That isn't…okay, yeah, he likes Blaine. But Kurt knows that he liked Blaine before any of this happened and he knows he went into this knowing exactly that. Maybe he was setting himself up for heartbreak but that's not why he's looking at Blaine the way he does now. That had nothing to do with his hands and his lips and –

He can't it let all crumble down so easily.

"Blaine, that's not why I've been looking at you," Kurt says.

And Kurt's proud of himself because it's only a partial lie.

"I'm not stupid," Blaine says, his voice hard. Kurt doesn't expect his words to come out so harshly. "You like me. More than just friends. And I told you in the beginning that I didn't want that. I don't want a relationship with you."

"I'm not calling you stupid. I know you-"

"I don't need you mooning over me like a lost puppy or something. Obviously I shouldn't have offered to teach you about sex and that's my fault. I should have realized how attached you'd get. You want more than just friendship and you want more than just sex but I don't-"

"How dare you?" Kurt hisses. "How can you sit there and – and presume to tell me how I feel?"

"I'm not presuming anything. You make it really obvious, Kurt."

"Well obviously your powers of visual deduction aren't quite as honed as you think they are because that's not why I'm looking at you. I know that you don't want a relationship. I know that we're just friends and I went into this whole thing knowing exactly that. So for you to assume that I'm not holding up my end of this little bargain is just…conceited. You're conceited. I'm not mooning over you like a lost puppy, Blaine. Just because I'm gay and just because you're the only gay friend I have doesn't mean I'm tripping over myself for your attention. It doesn't mean that I'm starving for your affection. Believe it or not I understand the rules that we laid down and I understand how I feel."

Kurt only feels a tiny bit of hypocrisy eating away at his conscience because he does like Blaine more than a friend. But he already knew this. Nothing has changed.

And the freaking point still stands.

"Then why do you look at me the way you do? Why do you do it?"

"Maybe because I can't stop thinking about how fucking amazing it felt to have your fingers up my ass for the first time the other night!" Kurt shouts.

Blaine's eyes grow wide with shock and he falls silent.

"Maybe because I can't stop remembering how good it feels to have your hands on me or your lips on my neck. Or because I can't stop thinking about kissing you. But I'm not looking at you because I'm – longing for your heart or something terribly cliché like that. I'm staring at you because I'm horny damn near all the time now and it's all in thanks to you and your stupidly smooth lips and your fingers and-"

Finally Kurt realizes all the words that are spilling out of his mouth and he snaps his jaw shut.

"I don't – I can't believe that that's really the only reason," Blaine whispers. "Sex stuff is just…sex stuff."

"To you, perhaps," Kurt bites out, standing and snatching up his bag to tug onto his shoulder. "But for me, someone who's never experienced anything else, someone who was pretty much terrified of it all to begin with, it means a little more. So you can either believe me or not. You can end it all based on your stupid assumption or you can continue teaching me. In the mean time, I'll be in the library until curfew."

Kurt storms over to the door and just as he's about to turn the knob, he stops and turns back to face Blaine.

"And it's not like I'm completely unattractive," he sneers. "Now that I at least have a vague sense of what sex is all about, I'm sure I could go out there and find someone else if I really wanted to."

He doesn't stay to see the look on Blaine's face.

The door slams shut behind him.
