Summary/Warnings: Sequel to 'It All Started With A Question,' 'Lucky' and 'Feel This Good'. They're going to work through this. It may not always be easy, but they've got the whole summer to figure themselves out. (Finn/Kurt/Blaine) (I think that, since I have no idea where this thing is going, I'm going to consider everything from here on out to be part of a chaptered story as opposed to a series of one-shots. It just makes it easier to keep track of!)

Disclaimer: I, unfortunately, do not own these characters, no matter how sad that makes me. I do, however, promise to return them when I'm done with them. :)

Summer Harmony

Prelude

"You have to tell Rachel."

"What? No freaking way, dude!" Finn sputters, nearly choking on the Coke he's currently guzzling, but Kurt's staring at him intently and he knows he can't run away from this one. He coughs a little and leans on the counter, staring at Kurt once he's gotten some margin of control back. "What am I gonna tell her? Hey, Rach, I've been chasing you for like forever but I have sex with guys on the side?"

"You don't have sex with us, Finn. You've given me about half a handjob," Kurt snorts, and Finn opens his mouth to protest.

"I gave Blaine…"

"Blaine was so hard he just needed somebody to touch him and he'd come. That's all," Kurt smirks, looking far too smug. "But I'm serious, Finn. You need to talk to Rachel. Either break up with her or…explain this…"

"I can't!"

"Finn, think about it. Rachel's one of those girls who isn't going to lose her virginity until she's married. What's the farthest you've gone with her?" he asks seriously, and Finn knows he's right; he knows it.

"Um, I touched her boob. Over her sweater."

"Well, I've touched her boobs, too," Kurt rolls his eyes. "Admittedly it didn't have me thinking of the mailman…" and Finn blushes at that, "…but we're even. Plus Rachel and Blaine dated, and Rachel and I are pretty close, and…I think she can handle it, Finn. She might even be happy that you've found somebody so she can continue to focus on her career."

"…You really think so?"

"I really don't know," Kurt admits with a rueful laugh. "But all three of us are around her far too much for this to be kept a secret."

"Yeah. I…you're right, dude, I just…don't know if I can tell her," Finn shakes his head sadly and continues drinking his Coke, polishing off the can and letting out a rather impressive belch.

"Such a boy," Kurt wrinkles his nose and Finn laughs, chucking the can in the nearby recycle bin.

"I'm gonna talk to Rachel," Finn nods, knowing that he has to. Kurt's right; they're not gonna be able to keep this one under wraps. "I don't wanna lose her, but…I'm not lying to her, either."

"Well, good luck," Kurt waves from his place on the counter and Finn rolls his eyes, burping again for good measure and laughing at the absolutely disgusted look on Kurt's face as he leaves the room.

He's really laughing to cover up his nerves, though.

Because he's totally freaking out.

"Rach?"

"Yes, Finn?" she asks, turning around from her dresser.

"Um. I've…got something to tell you."

"You know you can talk to me about anything, Finn," she smiles at him and crosses to the bed, seating herself beside him and reaching for his hand. He lets her take it, studying her carefully before heaving a sigh and knowing he has to go through with everything.

"Rachel…you know I love you, right?" he asks hesitantly, seeing her eyes light up the way they do every time he says the word, and she nods enthusiastically.

"Of course. I love you, too," she gives him a chaste kiss on the lips and he resists the urge to deepen it. "So what's the problem?"

"Um, I think it's great, y'know? That you want to wait to…get intimate with me until, like, you're completely ready and you don't care about losing your virginity in high school or anything, but…I do. I mean, I did. I'm not a virgin," he adds slowly and she nods.

"I know, Finn," she promises with a sad smile. "I still fail to see what this has to do with…"

"What would you say if you knew that I was fooling around with other people?" he blurts, seeing her brown eyes staring at him in shock, and okay, maybe that wasn't the greatest way to handle things but at least it's out there now.

Right?

"Finn…if I'm not…if you…"

"Rachel, I just said that I totally admire you for sticking to your beliefs and I'd never try and force you into anything but…I just need it, I guess. And I'm not trying to sound like a sex addict, but…"

"Who?" she asks, looking close to tears. "I need to know, Finn. If we're truly being open with each other, you have to tell me."

"Kurt," he says, biting his lip. "And Blaine."

Rachel opens her mouth, looking at a loss for words (and that, Finn thinks, is really rare), before she questions, "So, are you…"

"Nah. I mean, it's just…"

"Kurt," they say together, and she nods. "I should have guessed. Kurt's obviously very special to you and the two of you will never have a conventional relationship as stepbrothers, but Blaine?"

"Kurt won't…do anything with me unless Blaine's there," Finn admits. "And he's a cool guy."

"And an excellent kisser," Rachel blushes before shaking her head. "Sorry. That was uncalled for. But you're…what do you do?" she turns her head to the side, blinking.

"Just…fooling around, mostly. We haven't had sex or anything. I'd never go that far with a guy, I don't think, and Kurt's really skittish about getting intimate so he won't let Blaine go that far. It's just…release. I don't love them like I love you, Rachel, but I needed to tell you the truth. If you wanna break up with me that's totally cool; I get it," he blinks rapidly, really hoping she won't, and she eventually breaks into a smile and squeezes his hand.

"Thank you. For telling me," she clarifies, kissing his cheek. "I can't say this isn't a little bewildering, but then again, I think the four of us are bound to always be a little…"

"Less than normal?" Finn laughs and she agrees with a pretty smile. "Rach, seriously. If you're not cool with it I'll stop."

"Do you enjoy it? With them?" she asks seriously.

"Yeah," Finn says without hesitation, because he does. He loves seeing Kurt so happy, so trusting, so different from the composed façade he puts up for the world all the time. And Blaine's just…Finn's so glad Kurt's found somebody like him. "They're kinda awesome."

"Then you have my permission," Rachel pats his hand and continues to smile at him. "It hurts a little, of course it does, but I realize that I've told you you come second to my dreams and it would be unfair of me to expect you to devote yourself entirely to me when I cannot do the same. Plus, when the four of us move to New York next year, the more comfortable we all are with each other the better."

"New York," Finn breathes, still unsure as to whether he'll go with them, but…how could he not? "So, we're okay?" he asks haltingly, grinning when Rachel kisses him on the mouth and actually slips him a little tongue before pulling back.

"We're okay. It might take me a while to get used to this, but…"

"Rach, I swear, when you're ready for us to…to take that next step? I'll stop it with them. I'll stop it anytime you ask."

"I know you will, and I'm not going to run your life like that," she folds her hands in her lap and sighs. "Besides, I have to admit that thinking of you three…it's a bit of a turn on, if I'm being honest."

"You…" Finn blinks. "Wait, what?"

"Well, think about it this way: when you imagine Santana and Brittany doing…whatever they do…do you become aroused?"

"Um, yeah. That's hot," Finn says this like it's the most obvious thing in the world. "And sometimes I imagine Quinn with them and…"

"I do not need to hear your sexual fantasies," Rachel tells him bluntly before sighing. "The point I'm trying to make is, if you find the idea of two or three girls fooling around appealing, why should I not find the thought of three boys doing it equally as arousing? Besides, Blaine's attractive. I did date him. Briefly," she adds.

"So, you're cool with it?"

"I believe so," she smiles at him again. "Now go. My fathers will be back soon and they don't trust you fully yet," she laughs as he stands up. "And give my best to Kurt. Tell him we'll have to get together this weekend for a movie marathon."

"Okay. I will. Thanks, Rachel," Finn says honestly and she waves him away so he just smiles at her before leaving the room.

Well.

That went better than expected.

And the way he saw it, the less guilt he felt when doing stuff with Blaine and Kurt, the better.

Rachel really was pretty awesome.

"What do you think she'll say?" Blaine inquires, one hand stroking Kurt's exposed neck and collar while the other boy arches and sighs at the touch. "Am I being too distracting?"

"A little," Kurt admits, head lolling to the side as he smiles at his boyfriend. "But I honestly have no idea. I don't think, after what Rachel did to Finn, she's in much of a position to complain about this when Finn's being honest with her, but…"

"I dated her. It's Rachel. I get it," Blaine laughs and covers Kurt's mouth with his own, playful kisses that leave them both giggling after a few moments. "So…"

"So?" Kurt raises an eyebrow. "So what?"

"Are we waiting for Finn to get back or are we starting? Because I have to drive up to Six Flags tomorrow to get ready for my audition," Blaine reminds him and Kurt sighs.

"Did you have to take a job that's a day's trip away? You'll barely be home," he pouts, knowing he sounds childish but he had been looking forward to a summer with his boyfriend and now Blaine was leaving.

"I know, babe, but I have to do this," Blaine sighs and lets his forehead rest against Kurt's. "I promise, every free hour I have will be spent with you. Okay?"

"Okay," Kurt concedes, because it's all he can do.

"So, are we starting?"

"Yes," Kurt pulls him close and kisses him again. "I'm not going to wait for Finn to find out the answer is 'no.' And if it's yes he can join in."

"Mm, I like the way you think," Blaine moves to kiss his neck again, undoing the buttons on Kurt's shirt and spreading it open as his lips follow his fingers, detouring a bit in order to lave his tongue over one of Kurt's nipples as the other boy gasps, because he's almost embarrassingly sensitive there but it probably doesn't matter.

Not when Blaine's doing that with his tongue and lips and teeth, Kurt's body arching toward his mouth instinctively as he hears the door open.

"Hey, so I'm…wow. Dudes."

"Hey, Finn," Blaine barely looks up from his work, teeth closing lightly around Kurt's nipple as Kurt lets out a rather embarrassing moan, throwing his head back and he really wanted to ask Finn something…something important…but his brain can't seem to form a coherent thought right now. Blaine finally pulls back but his fingers keep teasing the peaked buds, rubbing his thumbs over them as he asks, "Any news?" and no, Kurt's not finding it any easier to figure out what he was supposed to say.

"Are you gonna keep doing that, dude? Kurt looks pretty out of it," Finn sounds a little amused and Blaine laughs and moves away, leaving Kurt painfully aroused and hoping this conversation goes quickly because he doesn't think he'll last much longer.

"Anyway, Rachel?"

"Yeah," Finn breaks into a smile and Kurt feels his heart beat even faster. "She said yes, and I told her that if she tells me to knock it off I will, but…she's okay with it. She, um, said she thought it was kinda hot, actually."

"Well, we are," Blaine laughs. "That's not really a secret. Anyway, you in?"

"Um," Finn pauses, still looking reluctant, and Blaine gropes at Kurt through his jeans as Kurt, feeling helpless, lets out another wanton moan. "Yeah. Coming," Finn nods, that seemingly deciding it for him, and shucks his shirt off before sliding out of his jeans and hopping onto the bed, hands instinctively reaching to smooth over Kurt's chest as Kurt turns toward him. "Rach says you and her need to have a movie marathon this weekend," he adds, just touching, and Kurt sighs happily and nods.

"Yeah. Sure. Movie-ah!" he groans as Blaine's somehow managed to undo his fly and slide his hand inside of Kurt's jeans, rubbing slowly, and Kurt has the presence of mind to ask, "So, are the two of you actually…oh, God, Blaine, don't stop…are you two going to…finish this time?"

"Um," Finn looks like he wants to say 'yes' but isn't sure if that's the plan, and Blaine looks up at Kurt and shrugs.

"That's not what's important…"

"Yes, it is," Kurt snorts. "As much as I appreciate the attention, I have to say that it's a little unfair for the two of you," he's not sure how he gets that all out but he does, somehow, and both Blaine and Finn stop to look at him.

"Kurt," Blaine says slowly. "You do realize that, if it weren't for you, this wouldn't be happening? Finn's a great guy but I'm not going get naked with him and fool around because I don't feel that way about him, and I'm sure he feels the same."

Finn nods in agreement and okay, Kurt can accept that, but… "That still doesn't explain why the two of you are so reluctant lately. You were obviously okay with it the first couple of time," he smiles, cocking his head to the side, and Blaine looks down before meeting his eyes again. "I want you boys to enjoy yourselves, you know?"

"Yeah. We just…wanted this to be good for you," Blaine explains and Kurt snorts and pulls him up for a kiss.

"You're an idiot, Blaine Anderson. The fact that you're doing this at all makes it good for me," he promises, because it's true: never in his wildest dreams could he have imagined something like this. "So come on, strip."

Blaine laughs at that and stands up, getting out of his clothes while Kurt watches with veiled hunger in his eyes and Finn, true to form, tries to look elsewhere. Kurt eventually just pulls him in for a kiss, sighing into his mouth and wrapping his legs around Finn's waist, trying not to squeak when the taller teen nearly lifts him from the bed and holds him steady, back barely touching the covers.

God, Finn's a giant, and Kurt adores that about him. "Hey," Finn says quietly, breath tickling his ear, and Kurt sighs against his shoulder. "Um, so, do you think I could…I dunno…suck you off?"

Kurt laughs haltingly at that, squeezing his legs around Finn's waist, and tries to get over the shock of hearing that question asked. "Sweetie, you know you cannot possibly claim to be fully straight if you do that."

"I know, man," Finn assures him. "But it's just…I thought about, like, eating a girl out, and this grosses me out way less. And it shouldn't, but that's the truth."

"Okay, did not need to hear about female privates," Kurt rubs his temples, trusting Finn to hold him up, and decided that it couldn't hurt. Finn could stuff a whole hot dog in his mouth so honestly giving a blowjob shouldn't be that difficult. "But okay. And I'll…do the same for Blaine while you do that," he turns his head to smile at his boyfriend, whose eyes light up at the suggestion.

"Cool," Finn kisses him once more before carefully laying him back on the bed and scooting down, Blaine stripping off his own underwear before joining Kurt on the bed and kissing him softly.

"Are you sure, babe?"

"Yeah. Completely," Kurt assures him. "I love you, and I trust you, and I want to do this."

"Okay," Blaine smiles widely and gets onto his knees, hands braced against the headboard as Kurt positions himself between the other teen's legs and smirks up at him, surprisingly calm as he allows Finn to remove his underwear and shudders at the feeling of his stepbrother's hot breath over his erection. He lifts one hand to grip the base of Blaine's cock before licking experimentally at the head, pre-cum coating his tongue as he makes a face. "It gets better," the dark-haired boy laughs. "Trust me."

"It'd better," Kurt slides his mouth over the end of Blaine's cock, sucking softly, and Blaine groans and drops his forehead against the headboard.

"Good," he manages to get out, Kurt smirking before he nearly chokes and has to pull off of Blaine to yelp.

"Finn, God, do you not have a gag reflex?" he gets out between gritted teeth, because he was expecting Finn to maybe lick at him and take him in slowly, but he's got Kurt's whole cock in his mouth and yes, it's amazing, but it's a little shocking.

"Um, no?" Finn mumbles…actually mumbles around his cock and oh, God, the vibrations.

Okay. He tries to put those feelings in the back of his mind and concentrates on pleasuring Blaine, taking his cock in as far as he can and sucking gently before humming, feeling Blaine's whole body shudder at the action.

And yes, he has to admit that having Blaine so responsive and so under his control is a little empowering and kind of ridiculously hot, but Blaine's enjoying himself so Kurt feels no guilt over it.

He sucks again, taking Blaine's cock in a little farther, and Blaine gasps and hangs one hand down to swipe at Kurt's hair. "Kurt…Kurt, get off, I'm gonna…"

Kurt pulls off immediately, not ready for that yet, and decides the sheets are going to make a noble sacrifice as he slides his hand down Blaine's spit-slick cock and a couple of firm strokes has him coming, cum staining the sheets and Kurt licks a little off of his hand and yes, definitely going to be an acquired taste on his part.

Blaine laughs weakly and slumps beside him, nuzzling his neck. "Good?"

"Yeah. Thank you," he kisses Kurt as Kurt pays attention to Finn again, realizing that he's a lot closer than he realized as Finn swallows and he tries to warn the taller boy; really he does, but Finn won't let him move and he comes with a low moan, hips pumping as Finn's throat works to swallow all of his ejaculate.

But then, Finn can down a bottle of Coke in one gulp so really, this is probably nothing.

He finally pulls off, Kurt feeling rather dazed, and he barely realizes he's urging Finn to lay on the bed with him as his lips find the taller boy's, tasting himself on Finn's tongue and okay, already getting used to it. He reaches down and rubs at Finn through his boxers, knowing that's all it will take, and Finn comes with a grunt, eyes wide and looking a little ashamed before Kurt kisses him again to cover it up.

Somehow they end up under the covers, cum-stained sheets ignored, all three of them stark naked and entwined in a way that Kurt's betting is going to be near impossible to sort out.

He hardly cares.

"I wish you didn't have to leave," he finally says to Blaine, fingers carding through the other boy's unruly hair, and Blaine kisses his shoulder and hugs him tightly.

"Like I said, every spare moment I'll be over here with you. I couldn't stay away if I tried," Blaine swears, fingers tangling with Kurt's as they kiss tenderly. "And you, Mr. Hudson; I hope you're never going to claim you're fully straight after this."

"Um. No," Finn laughs haltingly. "But dude, it didn't feel wrong, even though I should totally be like running around screaming or something."

"Don't. I'm comfortable," Kurt tells him, reaching out with his free hand and curling it around Finn's hip to hold him in place. "And you can have your big gay freak out later."

"Not gonna happen," Finn promises, mumbling the words into Kurt's shoulder.

"Take care of him while I'm gone, alright, Finn?" Blaine says sleepily, eyes barely open, and Finn leans across to kiss him as if to seal the promise that way. "Mm. And don't do anything I wouldn't do."

"You realize you're giving us a lot of options?" Kurt teases, feeling Finn's chest vibrate with laughter against his back.

"Yeah," Blaine slurs, eyes slipping closed as his breathing evens out, and Kurt chuckles and kisses him on the forehead.

"Summer's gonna totally rock, isn't it?" Finn says against his skin and Kurt can't help but agree, so he reaches for Finn's hand where it's resting on his stomach and clasps his own over it, knowing that he'll never tire of this…any of this.

"Yes, Finn Hudson. I think I can safely say that it is."

Notes:

1. So my last series like this was all named after chess moves, and I know absolutely nothing about chess, but this one I'm thinking they'll all be named after songs or types of songs. Which, since I spent thirteen years of my life taking piano lessons, I know bit more about xP

2. A prelude is kind of an introductory piece of music leading toward something bigger.

3. Um, hope you all enjoyed :)
