Pairing: Kurtbastian
Rating: NC-17
Summary: Kurt Hummel finds an unexpected acquaintance with Sebastian Smythe after a tough break-up. He tries to keep their fling a strict Friends with Benefits situation, but Sebastian starts to break through his carefully guarded walls, even though he isn't necessarily an open book, either.

A/N: Wow, it has been a month since I updated! I am so sorry! I promised myself a week between updates, but this chapter was ridiculously hard to get out. A fair amount of Blaine stuff later in the chapter, but no bashing or anything as usual. I find it interesting how some people can comment and say "Omg. Blaine is such a douche," or "Omg. My poor baby Blaine," about the exact same scene. It must just have to do with your original opinion of him, I think. I love Blaine, so I think I take some pity on him in this story, but not everyone agrees (to which I do not complain). Anyway, 10 points to the house of the first person who can find the Friends reference. After this just one more chapter, which I swear will be out before Glee comes back! Enjoy!

"Come on," Kurt whined, dragging out the words. He sucked small kisses along Sebastian's collarbone in an attempt at persuasion.

"I don't get why you want to go, anyway," Sebastian said. "We can just spend the entire day in bed."

"It's the last Warbler party of the summer. Everyone is going their own ways and all of the guys aren't going to be in the same place for a long time. I don't get how you don't want to go. It's not like I asked you to go to the New Directions party the other day." He flipped Sebastian onto his stomach and straddled him before reaching to massage his shoulders. He kneaded with purpose, still trying to convince the boy beneath him to agree to go.

"Still not going. We've hung out with the guys a lot this summer. I see no need for lengthy teary-eyed good-byes," Sebastian said with conviction.

"Fine," Kurt finally acquiesced, but didn't stop his motions. "I'll go by myself, then."

"What? No. Stay," Sebastian whined, flipping back over. He pulled at Kurt's hips until he had the boy's full weight on top of him. He nipped lightly at the crook between Kurt's jaw and ear, trying to do his own persuading as he started sucking marks along Kurt's collarbone.

"No, no, no," Kurt said, smacking his hand away and trying to sit up. "No hickeys. I am not wearing a scarf to a pool party.

"So stay. Please?" Sebastian begged, twisting his fingers in Kurt's hair at the back of his head and pulling Kurt's ear to his mouth. "Stay. I want you to fuck me again," he murmured. "I bet I'm still loose for you." Kurt shifted, trying to ignore the hot breath and rugged voice laced with want in his ear. His cock twitched with interest as it slid against Sebastian's already fully-hard erection. He finally managed to twist himself out of Sebastian's grasp.

"I'll take a rain check. I really am going, though. I'll text you when I'm home and you can come over if you want."

Sebastian humphed unhappily. Kurt pulled out the outfit he hung in Sebastian's closet the previous night, dressing quickly and casually and going into the bathroom to start doing his hair. After about fifteen minutes Sebastian came into the bathroom, fully dressed in a t-shirt and cargo shorts, and started brushing his teeth.

"And where are you all dressed to go?" Kurt asked with a smirk.

"Fucking Warbler party," Sebastian mumbled begrudgingly as he spit. He grabbed a towel to wipe off his mouth. Kurt grinned, continuing his work until his hair was perfectly coiffed. Sebastian ran a brush through his and sprayed it a bit to complete his messy-but-naturally-sexy look. "Are you going to borrow one of my bathing suits?"

Kurt shook his head. "After all the time and effort I put in to doing my hair? I am definitely not going swimming."

"What? You're dragging me to this thing and I don't even get to see you all wet and shirtless?" Sebastian complained. Kurt smacked him lightly.

"I'm not dragging you anywhere. I told you I'd go by myself. I just think it'll be good to say good-bye to everyone," Kurt told him. Sebastian just rolled his eyes.

Sebastian drove them to Nick's house and as Kurt stepped out of the car he had his first worries about the implications of arriving with Sebastian. Sebastian came around the car to walk up with Kurt and his hand automatically reached out for Kurt's, a natural reflex that had been picked up in the last couple of weeks, which Kurt had finally become comfortable with. At the slightest brush of fingertips, however, Kurt withdrew his hand immediately, attempting a natural crossing of his arms, hands balled into loose fists. He saw Sebastian's off-put reaction from the corner of his eye, but neither boy mentioned it. Kurt had gotten used to their increased physical closeness and he was really working on keeping all of the soft kisses and cuddling and hand-holding from messing with his head, but it was completely different walking up to their friend's house. They had both been to a few Warbler functions throughout the summer, the first of which Kurt went to with Blaine, but since then Kurt and Sebastian had seen each other at the get-togethers and had been completely inconspicuous, keeping safe distances, but that was different. Even when they were alone then, apart from the kisses in the beginning and actual sex, they weren't affectionate with each other in any other way, so acting casual in public was an easy feat.

Their two little worlds were colliding, though. They had to compartmentalize the way they were around just each other and the way they acted around all of their friends. It was a challenge that Kurt hadn't been entirely prepared for, and he realized Sebastian didn't even think to be concerned that they couldn't touch or even look at each other for too long. It hadn't even been a great length of time since they started growing closer, but perhaps the period of time felt longer because it was so concentrated from how much time they were spending together. Regardless of how things had progressed, however, Kurt quickly got his wits together and focused his efforts on being purely friendly towards Sebastian when the door opened to reveal Jeff, still dry, but in his bathing suit and with a beer in his hand.

"Hey, Kurt. Seb. Come on in," he said with a little flourish. The boys entered the house and went straight to the backyard where the party was already in full swing. Many of the boys Kurt knew from his time with the Warblers were there, as well as a few younger boys he knew only from the parties and some of the guys' dates.

"You guys want anything?" Jeff asked. Sebastian immediately asked for a beer, but Kurt declined.

"C'mon, babe," Sebastian murmured, leaning in far too close to seem normal. "Don't you want to loosen up?"

"I'm sure you're plenty loose for the both of us," Kurt whispered back, allowing himself to be just a little flirty in front of their friends. The words had more of an effect of Sebastian than he had expected, though, and he became wary at the look Sebastian gave him, as if reminding him of how he left Sebastian hard and ready just less than an hour earlier. Sebastian reached an arm out and brushed his hand lightly along Kurt's side, leaving a tingling trail in its wake. Kurt shivered ever so slightly and forced himself to break from Sebastian's gaze as he tried to skip backwards, but it became an awkward stumble. Only Jeff noticed the exchanged and he just cocked an eyebrow, handing Sebastian his beer.

Nick and Jeff were the only other Warblers that knew Kurt and Sebastian hooked up, partially because they were there the night Kurt went home with Sebastian after Chateau, but also because Nick was one of Sebastian's best friends in Ohio and likely told him some kind of version of what was going on, which he then probably gave a cliff notes version of to Jeff. Kurt was more than grateful that they could keep a secret, however, especially in the present moment when Jeff was watching them a little more closely. He may know they hooked up, but Kurt was pretty sure that even Nick didn't know that Sebastian and Kurt had been spending almost every night at each other's house.

Sebastian took a few large gulps of his beer, finally pulling it away from his lips and throwing Kurt an annoyed glare. Kurt tried to pointedly ignore him, quickly engaging in conversation with Trent, who had just pried open the cooler. He watched Sebastian tuck his hands in his pockets and breathed a little sigh of relief. Good. Maybe now he will keep them to himself.

Kurt had moved a little deeper in the backyard and finally noticed Blaine, leaning against the grill, talking to Thad. Their eyes met and Blaine's face pulled into the tiniest of smiles, meant only for him. At that moment Trent came up to him and started chatting animatedly about how the Warblers might have a chance against the New Directions the next year. He felt more than saw Sebastian come up behind him, trying to nonchalantly slip into the conversation, still not really in Kurt's eyesight. It worked for a few minutes until Sebastian leaned forward, his chest pressing against Kurt's back ever so slightly, but enough to drive him crazy with frustration. Sebastian's chin just barely rested against his shoulder when Kurt sidestepped him quickly, not so gently removing himself from the conversation. A glance back was met with an almost furious expression, Sebastian obviously chewing on his inner cheeks, eyes narrowed.

They kept their distance for a while, Kurt caught up in a conversation with Jeff, trying to ignore the looks he was getting from Sebastian across the yard. Eventually as others joined the conversation, Kurt allowed himself to casually slip out, strolling in the grass alone. Sebastian excused himself from his own conversation and followed Kurt, nudging him to a quieter part of the backyard.

"What the hell is wrong with you today?" Sebastian asked.

"What are you talking about, Sebastian?" Kurt asked exasperatedly.

"You won't even look at me. If I even touch you, you run in the other direction. So I repeat, what the hell is wrong with you today?"

"I—I'm not…," Kurt stammered, not expecting Sebastian to call him out so directly. "We're just…in front of all of our friends," Kurt tried to explain.

"So, what? It's not like I'm trying to fuck you in front of them."

"I know that. It's just—don't you think, I mean, we are still being inconspicuous, right?" Kurt was taken back with how Sebastian seemed to expect that not letting people know about their…relationship?...thing or whatever was no longer of importance. Even if they weren't exactly "Friends with Benefits" anymore, they still didn't want their group of friends to suspect that you were more than friends, right?

"Who the fuck cares, Kurt?" Sebastian asked, sincerely trying to figure out why being so secretive mattered anymore.

"Uh…I don't know. I do, kind of, I guess."

"Is it because Blaine's here?" Sebastian asked, voice weighed down with anger, hurt, and something like disappointment.

"No," Kurt assured him, even though it was true that he wasn't necessarily keen on the idea of rubbing whatever was going on with Sebastian in Blaine's face. He tried to think of some reasoning that would assuage Sebastian's fears and make him understand that Kurt was just trying to keep up the appearances they had in front of their friends all summer. When nothing seemed to be successfully coming out of his mouth, Sebastian rolled his eyes, with much more anger behind the gesture than usual. "I don't get why you're getting so mad," Kurt whisper-shouted angrily, just quiet enough for no one to over hear. "We're not actually together."

Sebastian's expression immediately transformed from one of clear anger and frustration to a frozen, almost unreadable mask. Kurt felt immediate regret at his rough words, no matter how true they technically were. "You think I don't fucking know that?" Sebastian responded, tone too calm for the resentment Kurt could feel lurking beneath the front Sebastian put up. "I'm going swimming," he announced, pulling off his shirt and cargo shorts to reveal his navy blue bathing suit. Kurt faltered slightly at the quick movements, watching Sebastian's muscles flex and move as he tossed his clothes onto a chair and walked back to the patio to grab a water bottle.

"Woah, Seb," Thad called as Sebastian came into his view. "You know you have a bite mark on your back, right?" There were a few catcalls at that, and while Kurt blushed horribly, trying to act completely removed and uninvolved, Sebastian quickly took it in stride.

"Yeah. The guy I fucked earlier has a thing for biting, I guess," he responded with a mocking grin. Kurt immediately turned, walking to a far edge of the backyard, trying to ignore their friendly laughing and teasing. He had just perched himself against large, decorative boulder when he saw Blaine bouncing towards him, hair almost free of gel and bouncing slightly.

"Hey," he greeted Blaine.

"Hey. You have a sec to talk?" Blaine asked. Kurt nodded, already wary, but Blaine seemed relaxed enough, which meant he likely didn't hear Trent's comment. "How are you?"

"I'm…you know. Same as always. Getting ready for New York," Kurt replied.

"Right. Just two more weeks, right?"

"Yeah. It's pretty crazy," Kurt said. "How have you been, Blaine?" Blaine shifted a little uncomfortably at that, his smile becoming more tentative.

"I'm…alright, I guess," Blaine replied. "I've kind of been wanting to talk to you after…you know, that whole thing."

"Right." Kurt nodded absently, not sure what he should say or even what Blaine wanted to say. Blaine's conversation with Rachel was still clear in his ears (I've completely ruined everything, haven't I?), but he never did gather the courage to call Blaine and give him the opportunity to say what he wanted to.

"I really left things awfully last time. And the time before that," Blaine added. "But I really had no right to get so upset about you going out with Sebastian. It just…really surprised me, I guess."

Kurt kept his mouth clamped shut. There was no effective way to give into his automatic first instinct to explain that he really wasn't dating Sebastian without telling Blaine that he was just sleeping with him, which wasn't exactly comfortable conversation material. Even if it was though, a grumbling voice in the back of his head (that he didn't find so bothersome anymore) reminded him that he couldn't really call their whole thing just "Friends with Benefits" since they were together at some point almost every day and most nights and emotions were steadily making their way into their...mutual partnership. With all of the nagging and mentions from Rachel, Mercedes, and his Dad, Kurt simply became exasperated with the need to add labels to it. He just enjoyed being with Sebastian. Well, he amended, thinking of the current fight he was in with Sebastian, most of the time.

"I really am sorry about the way he showed up like that at the coffee shop. I swear I didn't mean for that to happen."

Blaine responded with a chuckle. "I believe you. I'm pretty sure you said something about finding creative ways to hurt him." He sobered quickly. "I just…I wanted to tell you that I really do want to be your friend, like I said at the coffee shop."

"I want to be your friend, too," Kurt said softly, gently resting his hand on Blaine's.

"I just think I needed a little more time to actually realize that than I thought," Blaine admitted. "I've been working really hard to get over you this summer, and it just kind of shocked me that you'd gotten over me so quickly."

"I didn't—"

"Just wait. I know I can't really say anything because, well, I'm the one who walked out that day, but it was still really hard for me to see you moving on." Blaine paused, almost as if he was waiting for Kurt to interrupt again. When he didn't, Blaine squeezed Kurt's hand and continued, "At first I kind of freaked out, both at the Lima Bean and for a few days after. I wanted so bad to just call you and apologize for running out, but it just really hit me that you probably didn't want to talk to me."

Kurt forced himself to let Blaine continue, swallowing down his protests. Of course he wanted to see Blaine, wanted to be his friend, but he knew that Blaine was probably referring to more "getting back together" kind of talking.

"I swear I'm not as much of an emotional wreck anymore, though," Blaine said with a self-deprecating smile. "I still think that breaking up was for the best. I'm actually kind of hoping that maybe it will be easier to be friends since it happened over summer and not when you were hours away from here."

"I'm really hoping for that, too," Kurt said warmly. "And I want you to know that I didn't just move on and get over you so quickly, either." He ignored Blaine's slightly disbelieving look. "I didn't. I worked hard to get over you, too, just in a bit of a different way and it turned into something I was completely unprepared for. I don't even know what, to be honest."

Blaine nodded. "I still don't understand the whole Sebastian thing. I'm not mad or anything, like I was before. I know we both started to be his friend again, but he was honestly the last guy I ever thought you'd go for." Kurt couldn't help but choke out a laugh.

"You and me both!" He let himself giggle a little as Blaine's mouth perked up into a grin.

"Well, one day you'll have to explain it," Blaine said. "But today is not that day." Kurt nodded in agreement. They may try to be some kind of variation of friends, but they certainly weren't ready to venture into detailed discussions of their relationships with other guys. Blaine heaved a great, relieved sigh, like he's just happy they're finally at a place of mutual understanding and the weight on his chest has lessened at least a little bit. Kurt felt a similar kind of relief, which caused him to pull Blaine into a tight hug, getting a little caught up in how warm and familiar it is, but still reminded that these aren't the arms he wants wrapped around him at all times anymore. Blaine returned the hug for a moment before laughing quietly in Kurt's ear.

"Sebastian looks like he's trying to burn holes through my body," Blaine informed him.

Kurt gave a final squeeze before pulling away, turning to find Sebastian, dry and still by the cooler with his arms crossed tightly across his chest and his glare setting in more deeply when Kurt meets his eyes.

"It's me that he's mad at, not you," Kurt told him. Blaine nodded absently, looking like he was thinking about asking for Kurt to elaborate, but he must have ultimately decided against it. He patted Kurt's shoulder.

"Hey, let's hang out once before you leave. Maybe a movie night with Rachel, Tina, Mike, and the rest, yeah?" Kurt smiled and nodded in agreement. "Good. Tina was yelling at me for not going to the New Directions party. I just…didn't know if you were bringing Sebastian and for some reason it seemed like it'd be easier to talk to you alone being at the warbler party with all of his friends, too. I was trying to avoid the whole 'Sebastian just watching us talk" thing," Blaine said with a small chuckle. This only brought Kurt's attention back to Sebastian, seething and still glaring in their direction. Upon meeting Kurt's eyes again, Sebastian pushed off the wall and strode into the house.

"I should go deal with that," Kurt said with a sigh. He gave Blaine a small wave and turned to follow Sebastian.

Even though he entered the house shortly after Sebastian, Kurt couldn't find him in the kitchen or living room and the down stairs bath room was empty. Kurt finally resigned himself to re-entering the party in the backyard, figuring he'd eventually have to ask one of the guys to take him home if Sebastian took off without him.

Half an hour passed before Sebastian re-entered the backyard with Nick by his side, who Kurt didn't even notice had disappeared in the first place. Both of them joined the group by the pool. Kurt sat at the edge with his feet in, and Trent and Jeff were on the bench near him, discussing their plans as members of the Warbler council for the upcoming year, not in too much detail, though, since Blaine tread water in front of them and he was technically considered the enemy. Thad had just joined the group to give his advice when he was interrupted.

"Jeff's going to run the whole club into the ground," Nick called jokingly as he came nearer.

"Thanks, baby, for all of the confidence." Jeff stuck his tongue out. Nick responded by taking a leap into the pool, dragging Jeff under with him as he hit the water. They both came up, sputtering and laughing.

"I'm incredibly disappointed I'm going to miss seeing my man all hot and authoritative behind the council desk," Nick said, pushing Jeff against the pool wall and pressing in for a deep kiss. Kurt was surprised that he had forgotten that Nick had graduated and would be leaving Jeff. Granted, he was only going to school in Columbus, but Kurt couldn't help but feel bad that they were being separated after only just becoming an official couple. He politely averted his eyes as the kiss turned into a mini-make out session, but it was unnecessary when Trent splashed the couple.

"Get a room. I don't want to swim in your cum," Trent complained jokingly, but he sobered quickly. "Oh, man. You guys have probably had sex in the pool, haven't you? I'm swimming in cum," he said, disgusted, resigned, and depressed. Nick and Jeff's roaring laughter echoed in the backyard, but Kurt could still hear Sebastian's quiet chuckle as he moved to stand by where Kurt sat.

"Hey," Sebastian said quietly as the others were distracted by more laughter and teasing. Kurt looked up to find Sebastian eyeing him cautiously and finally sitting next to Kurt, his eyes flicking once or twice to where Blaine was treading water, engaged in the conversation as it changed to the craziest places everyone had sex. Not only did Kurt not want to have to share his own answers, but he didn't want Blaine to share them for him, or worse, have to listen to Sebastian's essay-long list of unconventional places he's gotten off, only a few of which probably included him.

Before he could discretely remove himself from the conversation, though, Thad asked loudly, "What about you, Blainers? Craziest place?" The smile from laughing and joking with his friends quickly dissipated from Blaine's face as he shot Kurt a nervous glance, eyes wandering to Sebastian before focusing back on Thad. He cleared his throat awkwardly, clearly trying to stall a bit.

"Oh, uh, I don't know," Blaine said anxiously.

"Come on. Don't tell me it's something like 'the foot of the bed,'" Thad teased.

Blaine got almost defensive at that, annoyance in his tone when he replied, "No, not the foot of the bed. I guess it would be the, uh…" Blaine gave one last glance at Kurt and Kurt wasn't sure if he was looking for permission or something, but whatever it was, it was enough for him to finally give his answer. "The McKinley High choir room."

The guys laughed and teased while Kurt felt a deep blush creep up on his cheeks. Everyone knew that he was the obvious participant, but it didn't stop Jeff from asking, "What about you, Kurt?"

There was no right way to go about answering the question. He could agree with Blaine, obviously, but he doubted the guys would allow that as an answer. He could give a new answer of a strange place he and Blaine had had sex, maybe bring up the blow job in the deserted movie theater, but he didn't exactly want to share more of his and Blaine's sex life than they already knew. His final option was bringing up an experience with Sebastian. They had only been having sex for a couple of months, but they had a few places that would definitely qualify as unconventional. This was an option he had to eventually shoot down because he was pretty sure most of the guys would think wherever he said would be with Blaine and the awkwardness of him or Blaine explaining that wasn't the case was not something Kurt wanted to get into. Besides, he wasn't sure he could spring that kind of thing on Blaine after they had just really reconciled things. Ultimately, he was stuck with the conclusion that there was simply no right way to answer the question.

"Kurt?" Jeff prompted.

"I'm not saying," Kurt replied.

"Come on. That's no fun," Thad complained. Kurt folded his arms and shook his head in response, trying to exude an attitude of being firm and immovable. "Fine, we'll get it out of you one day."

"Sebastian?" Trent asked and the leftover anxiety from Blaine's answer and being asked the question himself only intensified as Sebastian's face twisted into a cocky smirk.

"Well there's an airplane, a church, the library, the DMV," Sebastian drawled. "But my favorite encounter was in a Neiman Marcus dressing room," he said with the tiniest glance at Kurt. If Kurt thought he was blushing before, he had progressed to a nearly full-body, beet red flush across his chest, neck, face, and up to the tips of his ears. He determinedly ignored Blaine's eyes, preferring to try and naturally gaze around the backyard as if it became the most interesting setting in the world.

The change was either ignored or went unnoticed as Nick started talking about a blow job he got in a janitor closet at Dalton and the conversation moved on.

An hour later, as the sun was setting and a few people started to leave, Sebastian spoke his first word to Kurt since the "hey" when he joined the strange sex conversation.

"Are you ready to go home?" he asked.

"Do you want me to go home?" Kurt responded in question.

"Well, by 'home' I meant my home. Your dad gets back tomorrow morning and I don't want to have to wake up early."

"Oh. Well, yeah. I'm ready to go," Kurt replied, watching the delight in his answer soften Sebastian's features slightly. It was a welcoming change from the scowl he wore for most of the day.

There were no tearful good-byes, as Sebastian had feared, just (in some cases—empty) promises to keep in touch and small talk about future Warbler get-togethers for when the graduated folk were back in town for the holidays.

The next morning when Kurt stumbled into Sebastian's bathroom, he caught a glance at himself in the mirror and was pretty sure Sebastian's little jealous streak had earned him over a week of wearing high necked shirts and summer scarves.
