Undisclosed Desires

Chapter Eighteen

"We need to talk."

Blaine looks up, fear spiking through him because when Kurt sounds and looks like that it's never a good thing, but the other man smiles softly at him and takes his hand, leading him to the couch and sitting down beside him, not letting go of his hand.

"What's going on?" Blaine asks cautiously, transfixed by the way Kurt's drawing mindless patterns on his palm, long fingers fluttering over his skin.

"Finn and I…well, I admit that ever since you've talked about what you and he do I've been a little…insecure that he can give you something I can't. So I asked him to…to show me what he did to you so I'd know," Kurt looks vaguely embarrassed but Blaine's mortified, because no, Finn wouldn't have…

"And…did he…"

"He did. It didn't last long because I wasn't about to have sex while feeling like I was being punished for something," Kurt snaps, and his tone is angry although his fingers across Blaine's hand stay light, controlled. "Blaine, why couldn't you talk to me? Why did you have to…sex is supposed to be something beautiful, something that connects people, not something you use to punish yourself with," he says softly, hand moving to cup Blaine's cheek and Blaine sighs and turns into it.

"It wasn't always like that," he admits after a few moments. "I do…I do like it a little rough sometimes, Kurt," he shrugs and Kurt nods, accepting that. "The first time…he was upset about Rachel and I was there and it was rough just because we didn't really know each other that well sexually, and I liked that, but…" he shakes his head. "It turned into something else, and I don't know exactly when it happened and I don't think Finn even realized it for a long time, but it…it turned into me wanting to be hurt, and that sounds horrible, but…I felt like I didn't deserve you."

"Blaine," Kurt starts, staring straight at him and Blaine has to keep talking before he loses his nerve, loses himself in Kurt's stormy eyes and the lean lines of his body.

He has to.

"Don't, Kurt," he says quietly and Kurt stops, just staring at him. "Finn didn't…you know him, you know he'd never hurt me…never hurt anybody…so I don't think he knew how…how much he was hurting me, until I couldn't hide it anymore and he found out, and then he swore he couldn't do that anymore and things…changed after that," Blaine admits, because he's told Kurt the condensed version of this story before but…after what Kurt's been through tonight…he figures he deserves the real one.

"Blaine," Kurt says again, softer this time, and Blaine nods and lets him keep talking. "You don't ever have to do that," he promises in a quiet voice. "If you're…if you're ever in that much pain again, if you ever feel like you need to hurt yourself, you can talk to me," he says sternly. "I'm your partner, that's what I'm here for. I want to know everything about you, the good and the bad, and if we can't trust each other…" he trails off and Blaine takes in his words, gasping a moment later as the one hits him square in the gut and he feel like he can't breathe.

"I'm your…we…"

"I'm not asking you to marry me, but…yes," Kurt quirks his lips in a smile. "I've been in love with you for almost five years, Blaine Anderson. I don't want anybody else."

"Kurt," Blaine exhales shakily, unable to believe what he's hearing, that even after everything Kurt's still…he's… "Yes," he says, because it's the only thing he can say, and Kurt just beams at him and draws him into a slow kiss, cupping his cheek and pulling back much too soon for Blaine's liking. "What about…what about Finn?" he asks when he's sure his brain is working again, and Kurt's eyes cloud over at that for a moment.

"Finn…we need to show him he's as much a part of this as we are, Blaine, because I've been in love with him for seven years," he grins and Blaine has to roll his eyes. "I know that he's…that it's not forever, not with him, that he'll find somebody someday but for now…I am in love with him," he admits softly and Blaine sighs and draws him closer.

"Hey, don't do that. It's not a crime, Kurt. I think I might be a little in love with him too," he whispers, like it's a secret, and Kurt nods and curls up against him. "So what's our plan?"

"Tomorrow. Or whenever, but soon," Kurt replies, his own voice just as low as Blaine's had been. "We…do this right. I don't think when Sam suggested we all work it out he meant we group ourselves into convenient duos. If we're all in this together, we're all in this together," he emphasizes and maybe it's because Blaine's known him for so long now but he knows exactly what Kurt's talkin about.

"You mean an actual threesome?"

"I do," Kurt affirms with a strong nod.

"Okay," Blaine smiles, because truth be told he's rather looking forward to it and he knows the three of them will be fine with each other; that's been proven by the times they've shared a bed, or the time he walked in on Kurt and Finn and…

Regardless, it'll all be fine.

"Okay," he repeats slowly, drawing Kurt closer as the older man looks at him curiously. "You know I want that, Kurt, but tonight I…want you more. Is Finn…"

"In his own bed for once," Kurt snorts. "We changed the sheets after we were done and he passed out there but I wanted to wait for you."

"Good," Blaine wraps his arms around Kurt's waist and kisses him tenderly. "Are you…do you want to do anything with me? I'll understand if…"

"Hmm, well, I'll be sore for a while…" Kurt starts and Blaine flinches involuntarily because, in the end, that part's kind of his fault. Kurt, however, shakes his head and strokes fingers through his curls. "No, don't start with the guilt trip, Blaine. What I was going to say was that I may be too sore for you to do anything with me, but I can still make love to you," he nuzzles Blaine's nose with his own and Blaine sighs happily.

"Yes. That would be really great, Kurt," he smiles and Kurt smiles back before getting off of the couch and holding his hand, Blaine taking it after a brief moment and twining their fingers as they make their way to their shared bedroom.

It's peaceful afterward, Blaine thinks with a tiny smile. He's lying on Kurt's chest, sweat cooling on their bodies in the pleasant air of the room, and feeling a lightness in his heart that he hasn't felt in years.

"Mm," Kurt stretches, body flexing gently under Blaine's as he yawns and settles down again. "That was nice."

"Yeah," Blaine says, idly rubbing his thumb over one of Kurt's pink, peaked nipples as Kurt shivers pleasurably. It's a simple action, intimate without being arousing, and Kurt rests a hand on his back and strokes his skin softly. "Remember when I said I wished we could go back?"

"And I told you we couldn't," Kurt replies after a moment's pause. "You're not my teenage dream anymore, Blaine," he teases and Blaine laughs and ducks his head to press a kiss against Kurt's collar.

"Oh, trust me, I know," Blaine nods. "But I just meant…if it can be like this? I don't need to go back. I like where we are just fine."

And Kurt gives him a sweet, sad smile that's in equal measures heartbreaking and yet happy, and he twines his fingers gently with Blaine's and nods. "So do I. This…"

"We can make it," Blaine says immediately. "And one day…well, you said married by thirty, right?" he grins and Kurt sighs good-naturedly and swats at his hair, fingers stilling there a moment later as he just stares at Blaine.

"Mm-hmm," he agrees vaguely, staring at their joined hands, and eventually he just closes his eyes and snuggles closer, nose pressed under Blaine's jaw. "Is that a promise?"

"That's a promise," Blaine swears, because after everything…the alcohol and the cold, hard truth that he'd been only a few drops away from being dead…he knows that he wants to live, to wake up to Kurt every day and spend his life with this beautiful, beautiful man by his side.

"Good," Kurt reaches up to kiss him again, deeper, and Blaine sighs into his mouth and lets him take it over, raising their clasped hands above his head and just relishing the moment. Everything seems so simple now, and the gut-clenching fear that had driven him to drink, the guilt that made him pour everything evil into his system in some horribly backwards effort to cleanse it seems so far away and he hopes that it always stays that way.

No, he knows it will, because Kurt's not going to let him sink that low again, and he won't let himself sink that low without telling Kurt. He knows now that Kurt's not going to leave him over something like that, and the knowledge is comforting.

Kurt's mouth is still lightly pressed to his, eyelids fluttering with obvious exhaustion and Blaine kisses the tip of Kurt's nose and tucks him close again, closing his own eyes and preparing to sleep.

There's a creak of a loose floorboard and Finn's creeping in, obviously trying to be quiet but Kurt sighs and opens his eyes, rolling them a little at Finn's failed attempt at silence.

"Finn, you are not fooling anybody. Get in here," he says firmly and there's a tiny squeak from Finn's throat before he's clomping around the bed, all attempts at being graceful forgotten as he slides in behind Blaine and snuggles close, arms wrapped around his waist.

"Hey, dudes. Can I sleep here?"

"I already told you to get into the bed, and since you don't seem inclined to move, I'm guessing you're sleeping here regardless," Kurt's words are biting but his tone is fond, and when he cracks his eyes open Blaine can see the love there and it makes him smile.

Maybe at one point this would have made him extremely jealous, but he knows he has Kurt, and he knows that Kurt loves him just as much, if in a slightly different way.

"Yeah. It's comfier than mine."

"That's because you were content to buy whatever mattress was the cheapest while I actually did research," Kurt snarks back and Finn shifts a little against Blaine's back, doing something that has Kurt snorting. "That's mature. If you're going to stick that out put it to good use."

"Kay," Finn shrugs and the next thing Blaine knows Finn's dragging his tongue along the shorter man's shoulder, up along his neck and kissing the skin there.

"Finn…" Blaine's not sure what tone he's supposed to be using but he can feel Finn smile against his skin before he pulls back. "No, you don't…have to stop."

"Cool," Finn pauses for a split second before diving in again, mouth hot against Blaine's flesh, and Blaine lets himself relax even farther under the gentle touches.

Kurt's meeting his eyes again, fingers still not letting go of his, and Blaine has to admit that he's gotten almost used to sleeping with two other people in the bed. He feels safe and happy, and those are two things that as of late haven't been a big part of his life.

But, he thinks as he leans in to kiss Kurt once more, that looks like it's going to change.

And he can't be happier about it.

Notes:

1. This fic is drawing to its close! I'm thinking one more chapter and then an epilogue, so we'll see how that goes and I'll try to get them out faster than I have been. I apologize for the horrible wait on this one.

2. Self-promotion time! I've made a side tumblr blog that's entirely devoted to Klaine/CrissColfer and the like because, well, being a Kinn and Klaine shipper doesn't really work on one blog, as I've found. So my main blog, for anybody who doesn't know, is kind of a mix of everything and is currently at chris-and-cory(.)tumblr(.)com, and my Klaine blog is kurtbowtieletitsnow(.)tumblr(.)com Yes, the name came from one of those 'generate your Klaine username' things, and I kind of liked it :)

3. Thanks again for all of the comments/reviews on this fic, and let me know what you thought!
