Warnings: Threesome. Double Penetration. Pseudo-incest (sex between step-brothers).
Summary: Based on this prompt from the Glee Kink Meme: Kurt and Blaine dp Finn. Finn has been lusting over Blaine for years and he's come to terms with it and the fact that nothing will ever come of it. Until he goes to visit them in New York after all of them have graduated from college and Kurt has a suggestion for helping all of them with their bucket lists.
A/N: Yup. This happened.

Finn sighed happily and sipped his beer, relaxing into the soft leather cushions of Kurt and Blaine’s sofa. It’d been months since he’d seen them and yet seated on the couch in their small apartment in New York City, he felt more at home than he had in months.

“Need another beer?” Blaine asked, already reaching for the bottle Finn was balancing on his thigh. Finn smiled and handed it over.

“Yeah, that’d be great,” he said, watching as Blaine walked out of the room. Namely at his ass, because honestly, it was what had started this whole mess in the first place and Finn never missed an opportunity to give it another look.

Back during their senior year of high school when Blaine had just transferred, Finn had found himself getting continually irritated with Blaine, finding fault with everything he did and generally feeling really threatened by him. It wasn’t the time of his life he was most proud of because he knew he’d been kind of an ass about a lot of things back then, but it had led to a lot of glaring. Which had led to a lot of staring. Which had led to an appreciation of Blaine’s body. You know, just one guy admiring the fact that another guy has nice arms and stuff. But then he’d noticed Blaine’s ass and honestly, there just wasn’t a good excuse for him to be staring at Blaine’s ass. So that had led to a series of really confusing masturbatory sessions.

After awhile though, Finn had come to accept it. He didn’t have feelings for Blaine. He didn’t want to date him. He wasn’t gay, because as Santana had explained (though yelling would be a better word to describe what she’d done after Puck had asked how she could be a lesbian when she’d had sex with so many guys) sexuality is about who you love, not just who you have sex with. Or want to have sex with. Or jerk off daily thinking about having sex with.

Finn had never had feelings for a guy before he started having increasingly filthy daydreams about Blaine and he hadn’t had any since then. It wasn’t about feelings. It was about sex. Sex that Finn wanted desperately but couldn’t ask for because Kurt was his step-brother and Blaine was his boyfriend and they were more in love than he’d seen anyone other couple be in his entire life. Including his mom and Burt and they pretty much made him want to vomit on a daily basis they were so sweet to each other. He wasn’t about to jeopardize his relationship with Kurt and Blaine and their relationship with each other just because of some stupid fantasies.

“So Finn, are you enjoying being back in New York?” Kurt asked from the armchair to his left.

“It’s great! I can check seeing Yankee Stadium off my bucket list,” Finn said.

“Funny you should mention that,” Kurt said, smiling at Blaine and accepting the fresh glass of wine being handed to him. “Blaine and I have been working on our bucket lists. I’m amazed at how much we’ve already been able to check off.”

“Cool,” Finn said, taking a long sip of his beer and trying not to react as Blaine sat down next to him on the couch. Right on the center cushion instead of at the other end.

“There is one thing that we were hoping you might be willing to help us out with, though,” Kurt said, focusing his gaze on Blaine as he spoke.

“From your bucket list?” Finn asked.

“Yeah,” Blaine said, resting one arm on the back of the couch behind Finn’s head as he swiveled on the cushion to better face them. Finn swallowed hard, took another sip, and tried not to think about how close Blaine was or how good he smelled or how tight his jeans were or-

“Well, we were thinking that we would really be helping each other out. Because by you helping with ours, we’re pretty sure that we’ll also be helping with one of yours,” Kurt explained, but Finn still didn’t understand. Why would they need him for something from their bucket list and how could they possibly know what was on his? He had ‘Eat deep fried butter at the fair’ on his list, for god’s sake.

“So, what is it?” Finn asked, looking back and forth between them as they shared another look. They were both strung tight, jaws set tight, forearms tense from clenching their drinks tightly as they looked only at each other. They looked… nervous.

“We’ve both agreed that we would love to have sex with another guy at the same time, but the idea of picking up a guy in a bar and bringing him home just doesn’t…” Kurt trailed off.

“Do it for us,” Blaine finished. “We’d rather have it be someone that we trust. And… I’ve seen the way you look at me, Finn.” The breath Finn had just inhaled stuck in his lungs like someone had shoved a stopper down his throat and he could feel himself turn red.

“What? I don’t look at you. I mean I look at you. I’m looking at you right now, but, I mean, what are you even talking about?” Finn spewed out as soon as he was able to actually speak again, dropping his gaze to the floor and trying not to panic. He hadn’t been obvious had he? Oh god, how long had Blaine known?

“It’s okay. Blaine’s not upset. I’m not upset,” Kurt said, leaning in and resting his elbows on his thighs in an attempt to lower himself enough that he could catch Finn’s eye. “We know it’s not an emotional thing, because the way you look at him has nothing to do with love and everything to do with sex. We’re not mad. We want to help you.”

Finn couldn’t breathe again. It felt like he was going to turn purple from the lack of oxygen, his fingers digging into the green glass bottle in his hand, and into his left thigh. This wasn’t supposed to happen. Ever. It was just supposed to be his own little thing, something he dealt with regularly in the privacy of his bedroom and nowhere else.

“We want to have sex with another guy and you want to have sex with me. It’s a perfect opportunity,” Blaine said. Finn turned and looked at him. Blaine looked relaxed now, each slow blink fanning out his thick eyelashes onto his cheeks, his eyes dark and, whoa okay, turned-on looking.

“But, Kurt and I are step-brothers,” Finn said. “That makes this weird. Well, weirder.”

“Exactly. We’re step-brothers. We’re not blood related. We weren’t raised together. And besides, Blaine and I have already talked about this and he’s going to be doing most of the… involved work since we know that for you, this would be about Blaine and not about me,” Kurt said.

“Um… how much have you two talked about this?”

“A lot,” Blaine laughed. “Well, ever since we found out you were going to come visit us here.” He ran a hand through his hair and Finn could see those incredibly sexy curls (that he may or may not have imagined wet with sweat and sticking to his forehead on more than one occasion) slide between his fingers. Blaine didn’t wear as much gel as he had back in high school and Finn wanted more than anything to know what it would feel like to just grab on hard and-

“So what do you say?” Kurt asked. The three beers Finn had drank were making his head slightly swimmy, so trying to reason through this was going to take some effort.

On one hand, there was no way in hell he was agreeing to this. He was not going to have sex with Kurt and Blaine. That was weird and wrong and weird and would complicate things between them forever. It was also, you know, weird.

But on the other hand-which Finn was starting to suspect might be the hand that usually roughly jerked his cock as he careened toward orgasm while thinking of Blaine’s ass in a pair of snug jeans-he totally wanted to agree. He was being given an open opportunity to act on his desires. And they had picked him to do this with. They could have wanted to do this with any guy they knew or any guy they didn’t know, but they’d chosen him.

“Okay, so… question,” Finn said, his thumbnail scraping at the edge of the beer bottle’s label. “You said that you both wanted to have sex with the same guy, but that Blaine would be doing ‘most of the work.’ How is that possible?”

Kurt and Blaine shared another nervous look and Kurt stood, coming over to perch on the edge of the coffee table right in front of them.

“Well,” Blaine started, but he didn’t finish. The word hung awkwardly in the air until Kurt sighed and continued a little begrudgingly as if he hadn’t been the one scheduled to handle this part of the conversation. Now that Finn thought about it, they probably did have this entire thing planned out. Given Kurt’s history, there was probably a poster board somewhere with everything detailed and yeah, Finn really didn’t want to go there.

“When we say that we want to have sex with a guy at the same time, that’s exactly what we mean. We’re not just talking about a threesome. It’s a big fantasy for both of us to actually be inside of the guy at the same time,” Kurt said, blushing slightly when Finn’s eyes widened.

“You mean you want to… both of you… at… is that even possible?” Finn stammered, shifting uncomfortably at the thought.

“Oh it’s possible. You build up to it, but from what we’ve heard, it can be really hot,” Blaine told him. There he went with those turned-on eyes again.

Why was this happening? Why had Kurt ever gone spy on the Warblers so that he met Blaine so he started dating Blaine so Blaine transferred so Finn started to stare at him and realize how incredibly sexy he was? Hadn’t Puck been the one to suggest the spying? Yeah, this was all Puck’s fault. Finn made a mental note to punch the crap out of Puck the next time they got together to play basketball.

“And that’s what I meant when I said that Blaine would be doing all of the active work,” Kurt said. “There’s prep work involved and it’s best if just one person does the… fucking for awhile before the other person joins in. And even when the other person does, it’s usually easier on a first-time recipient if one of the guys just holds still and the other does the moving.”

Finn was pretty sure at that point that he’d forgotten how to close his mouth it had been hanging open for so long. They were actually serious. They both wanted to put their cocks in his ass at the same time. There was no way that would work and there was no way it could possibly even feel good, nor could anyone recover from something like that.

“He’s freaking out,” Kurt sighed, looking at Blaine and talking as if Finn wasn’t there.

“It’s just kind of a lot to take in,” Finn said. Blaine and Kurt both blinked at him before cracking up, Blaine going so far as doubling over and grasping onto Finn’s knee for support. That was incredibly distracting for obvious reasons as he tried to figure out why they were laughing at him all of a sudden. And then the double meaning of his words hit him and he felt his entire face go hot.

“Look, Finn,” Blaine said once he’d stopped laughing, wiping a tear from his cheek and turning on the black leather to face him again. “We know that this is asking a lot of you. I know that you’ve been thinking about me in that way for a long time, but I don’t know what your fantasies are. I don’t know if you imagined being on top or on bottom or if there was any sex like that involved at all. I just want you to know that we will do everything possible to make this amazing for you and that anal sex does feel good.”

“So good,” Kurt chimed in.

Finn started, having forgotten for a moment that Kurt was even there what with the closeness of Blaine’s body to him. As much as he wasn’t sure about this, about how much it sounded like there was no way it could possibly feel good, he knew that he was going to say yes. He’d been wanting Blaine for years and if they were promising to make it good for him, he believed them. And if he had to have Kurt… inside of him in order to have Blaine in so many ways, he’d do it. It was worth it to take care of the burning, at times impossible to handle lust he’d felt for Blaine ever since he first let himself acknowledge the fact that yes, he wanted Blaine and there was nothing he could do about it.

“Okay, I’ll do it,” Finn said, chugging the rest of his beer and blinking a few times rapid fire. Oh god, what had he just said?

“Are you sure?” Kurt asked. Finn looked at him and then over at Blaine, his eyes grazing over Blaine’s face before settling in on his lips. He was definitely doing this.

“Yeah, but I have to know something first. I need to know that you two are going to be okay after this. I won’t do this if you won’t be.”

“Finn, at the risk of offending you, you need to understand that Blaine and I are doing this for us. We want to do this together. When Blaine is fucking you, he’ll be fucking me, too,” Kurt said. “And we asked you because we know that you’ll get something out of this but it won’t be feelings that Blaine and I can’t reciprocate. Do you get what I’m saying?”

Finn fiddled with his beer bottle, passing it back and forth between his hands as he stared down at it. The second he said something, it would all start and everything would change. He wasn’t worried about developing feelings for Blaine, but he was a little scared of things getting so strange between the three of them that they would never be able to just hang out ever again. And god, what if his mom and Burt could tell that something was up?

“Yeah, I get it,” Finn said quickly, shutting up his brain and leaning forward to set his bottle on the table beside Kurt. “Okay, let’s do this.”

“Are you sure?” Kurt asked carefully.

“Yes I’m sure. Now stop asking me and looking at me like that. You’re kind of freaking me out,” Finn said.

“Hey, there’s nothing to freak out about,” Blaine said, reaching out and taking Finn’s chin in his hand, turning it until they were facing each other. Finn hardly had time to register the movement before Blaine’s lips were against his.

They were hot and insistent as they pressed against Finn’s, pulling and capturing and not doing anything more than really just innocently kissing. It wasn’t as weird as he had thought it might be, kissing a guy. Blaine’s lips were soft, but they were definitely guy lips. He was kissing hard, the slight scratch of a day’s stubble present on his chin as Blaine deepened the kiss with a swipe of his tongue across Finn’s lower lip.

With a moan that he would definitely be embarrassed about later, Finn opened his mouth to Blaine, letting Blaine’s tongue into his mouth to slide against his own. But far, far too soon he was gone, pulling back with a smile.

“Still freaking out?” Blaine asked reaching a hand out in Kurt’s direction while not losing his focus on Finn’s face. Out of the corner of his eye, Finn saw Kurt take Blaine’s hand, their fingers lacing together as Blaine kept his gaze focused on Finn.

“Definitely getting better,” Finn said, allowing himself to stare right back into Blaine’s eyes in a way he never had before. He’d always avoided lingering glances, afraid of what he might do or say to make a complete ass out of himself. This was great, though, really getting to look at him for the first time. He was so fucking hot.

Finn knew without a doubt that Blaine was the only guy he ever would be attracted to like this. Now, he could admit when another guy was attractive or had a nice body. He just didn’t react to it the way he reacted to Blaine. There was just something about him that did all kinds of crazy things to Finn’s insides. And his cock.

Mostly his cock.

“Good,” Blaine smiled, leaning back in for another kiss. Finn smiled just before their lips touched.

Kissing had never felt this good before. Blaine’s lips were so smooth, his mouth so warm as he sucked Finn’s tongue with the most insanely perfect pressure that Finn immediately imagined being placed around his cock. Hey, he couldn’t help it that most of his fantasies about Blaine had involved exactly that-Blaine blowing him in hundreds of different amazing scenarios.

He hadn’t really thought much about Blaine actually fucking him because well, he just hadn’t. While the idea of it was kind of terrifying in about a million ways, what was probably the most scary thing was that he was positive that he wanted to do this. He wanted to feel Blaine inside of him.

He wanted to know what Blaine could do.

When he felt himself being pressed back toward the arm of the couch, he went with it. Blaine was so much shorter than him and honestly that had always been part of the appeal. He was compact and tightly muscled, so much man squeezed into his frame that Finn honestly didn’t know how Kurt managed to keep his hands off of him, like, ever.

Blaine settled himself in on top of Finn, wasting no time in pressing his hips down, rocking against Finn’s already hard cock and letting him know that he was getting there, too. Blaine was at least half hard, the press of his cock against Finn’s pulling a moan from deep within Finn’s chest. Hesitantly, he started to touch.

He started off small, just settling his hands in on Blaine’s waist as they kissed, tongues tangling, moaning into each other’s mouths as their hips worked together in a desperate need for more friction. But then he got braver as a really loud and almost pained moan ripped its way from Blaine’s mouth as he pulled away, huffing hot breaths against Finn’s neck and placing sloppy, open mouthed kisses there.

It was getting hot in the room. Or maybe it was just them. Yeah, it was probably just them. But the point was, Finn was scorching. His shirt felt suffocating, his skin felt flushed, and yet even though the hot weight of Blaine on top of him should have been too much, it wasn’t. He wanted him closer. He wanted to feel if Blaine’s skin had been set on fire the way his own had.

So he slid his hands up the back of Blaine’s shirt, the material bunching around his wrists as he rubbed his palms across the impossibly smooth skin of Blaine’s lower back. It was warm to the touch yet hard and muscular and Finn just couldn’t help himself. He grabbed the bottom hem and pulled up, stripping Blaine of his shirt before pulling him down by the back of the neck for another kiss.

Now that there wasn’t a stupid shirt in the way, he could really feel Blaine. He let his fingers lead the way, wandering up Blaine’s sides and loving the way Blaine shivered on top of him as they skirted over his ribs, trailing down his spine between shoulder blades and trim muscle, feeling Blaine’s hips roll in again and again as they rutted together on the black leather.

“I’m going to start touching you now,” Blaine said against Finn’s lips. “Want to back out?”

“No fucking way,” Finn practically growled, leaning up in an attempt to get their lips together again, but Blaine was grinning and sitting up, straddling Finn’s thighs and pushing up his shirt until he got the hint. He sat up just enough so he could pull it off and toss it carelessly over the back of the couch. He tried to pull Blaine down, needing to feel Blaine’s bare chest pressed against his own, but Blaine wasn’t having any of it.

“Just lay back and relax,” Blaine said, his voice lower than Finn had ever heard it and fuck that was sexy.

Blaine slowly drug his hands up Finn’s thighs, the hot lines of pressure sending his hips up off the cushion, subconsciously trying to get Blaine’s hands where he really needed them, no matter how good it felt. And god did it feel good. When sure fingers made quick work of undoing his pants, Finn felt his cock get even harder. If that was even possible.

All Blaine did was yank his jeans and boxers down to mid-thigh and then he froze. Finn looked down at himself-at his cock hard and red and straining toward his stomach-just in time to see Blaine’s head come into view, his tongue sneaking out to lick a searing line from his balls to the tip of his cock.

“Oh fuck,” Finn moaned out, his fingers sliding into Blaine’s hair, wrapping curls around his fingers as Blaine’s mouth sunk down over his cock. His entire cock disappeared into that warm wet heat, every ounce of his being focused on the feel of Blaine’s tongue and throat surrounding him and the silky strands of hair coiled around his fingers.

Waves of pleasure coursed through him as Blaine moved up and down his cock, his lips sliding up and over the head to lave it with licks and kisses with every single upward movement. It was without a doubt the absolute best blowjob Finn had ever gotten and it was taking all of his self-restraint not to thrust up into that perfect mouth. When Blaine angled his head just right to look up at Finn through his lashes while he again deep-throated him, Finn’s mouth dropped open and he exhaled a shaky breath.

“How’re you doing?” Blaine asked as he pulled off of Finn’s cock and wrapped his hand around the length, stroking him slowly and far too lightly. Finn started to respond, but then realized that Blaine wasn’t talking to him. He wasn’t even looking at him. He was looking at Kurt.

Right. Kurt.
Finn had kind of forgotten all about him again.

He followed Blaine’s gaze and all of the air rushed out of his lungs. Kurt was leaning back, supporting himself with one hand splayed on the dark wooden surface of the coffee table as he jerked himself off with his other hand. All of his clothes were still on. He’d just pushed his jeans down enough to get at his cock. And oh my god. His cock was huge. Like, how had Finn lived in the same house with Kurt for years with absolutely no idea that his step-brother was hung like a moose?

“That is so not going to fit,” Finn blurted, swallowing hard as his eyes followed the movement of Kurt’s hand. No wonder Blaine could take his own cock in so deep if he was used to sucking that off.

“Trust me, it will. And it feels so good,” Blaine said in his ear before nipping at the lobe.

“Come here,” Kurt said, his voice scratchy and needy as he stared at Blaine all the while not stopping his hand on his cock. Blaine smiled and climbed off of Finn, the loss of his warmth and weight huge and oppressive. A surge of intense jealousy washed over him as he watched Blaine drop to his knees between Kurt’s spread legs, immediately sucking the thick head of Kurt’s cock into his mouth. “God, you’re so good at this.”

Blaine moaned in response, his fingers reaching around to dig into Kurt’s ass, pulling him closer to the edge of the table. His mouth moved down impossibly far over Kurt’s cock before Kurt was pushing him away.

“What’s wrong?” Blaine asked, curling his fingers around the base and moving his fist up and down no more than half an inch. Kurt hissed out and thrust hard up into Blaine’s hand.

“I just think you should get back to Finn, that’s all,” Kurt said breathlessly, nodding at the couch and catching Finn’s eye. “There’s so much yet to do.”

“That there is,” Blaine said. “Do you have-?” He didn’t finish his sentence because Kurt was reaching over and grabbing a bottle from the drawer in the end table right beside the couch.

Oh. That was. Okay. Right.

“Should I, uh?” Finn asked, already reaching for his pants.

Blaine nodded as he flicked open the cap of the lube and squirted some onto the fingers of his left hand, sliding them together as he set it back down on the coffee table beside Kurt. Finn pushed his pants and boxers to the floor and quickly yanked off his socks before lying back down. Kurt was unbuttoning and unzipping Blaine’s pants, licking his lips before leaning in to press several kisses to Blaine’s stomach as he slid them down his legs. His muscular legs.

God.

They were toned and perfect and even better than he’d imagined in his many, many fantasies. The dark hair that covered them shouldn’t have been hot, but it was. It really really was and Finn wanted to touch, so he did. With an unsure hand, he reached out and lightly slid his hand up the outside of Blaine’s leg.

There were so many things that Finn wanted to say in that moment, but nothing would come out. They all lodged in his throat, choking him until they finally broke through as nothing more than a moan that he tried really hard to keep soft. His cock was so hard it hurt, needing to be touched again soon or else he was pretty sure that he was going to die. All that was in the way of Finn finally seeing Blaine fully naked for the first time was a pair of black boxer briefs that Kurt was already pulling down. Blaine’s cock sprung up as soon as it was liberated from the hold the briefs had had on it, flying up toward his stomach.

“Jesus,” Finn breathed out, his gaze trained solely on that gorgeously swollen cock.

“You can touch it if you want,” Blaine said, a hint of smile present in his voice. Finn sucked in a breath as he was shocked out of his staring session by Blaine’s words. Kurt and Blaine were both staring at him, both breathing a little heavy. Yeah, Finn definitely wanted to.

He swallowed hard and wrapped his fingers around Blaine’s cock. It was the first time he’d ever touched a dick that wasn’t his own and it should have been weird but it wasn’t. Blaine was hot in his hand and the head of his cock was so smooth with precome visible in the slit. Before Finn could even process what he was doing, he was leaning in and licking it off.

That was all he’d intended to do, just give it one lick, but something grabbed hold of his insides and twisted them in a fiery vice grip. His cock twitched and he took hold of Blaine’s hips, pulling him in closer and sucking as much of Blaine’s cock into his mouth as he could handle. It wasn’t as much as Blaine could take, but it was his first time and based off of the moan Blaine was letting out, he was doing okay.

Blaine’s cock felt heavy on his tongue and it was a little weird, having something that big in his mouth period, but for some reason it was hot. Like, really hot. The way it tasted, the way it felt like silk on his tongue, the way Blaine was making these little noises in the back of his throat that couldn’t really be described as anything Finn had ever heard a human make before. All of it was just making Finn even hornier, his cock painfully harder, and any bits of trepidation he’d been having fly right out the window.

When he felt a hand on his shoulder, pushing him back, he dropped against the couch cushions. His lips felt swollen and he was pretty sure that he couldn’t have properly focused his eyes even if he’d tried. Blaine’s cock was wet. From Finn’s mouth.

Oh god. He had done that. Finn had just had another guy’s dick in his mouth. Blaine’s amazing and perfectly wonderfully normal sized (unlike the beast currently being tamed by Kurt’s fist) cock.

“Lie back,” Blaine said, climbing between Finn’s legs as he got situated. “Knees up.”

Okay, this was it. Something Finn had never imagined in a million years that he would do. But with Blaine kneeling there on the leather, one hand lazily stroking his cock and the other shining with lube, Finn knew he was ready. He would let Blaine do pretty much anything to him in that moment.

All Finn could see was perfectly placed chest hair and veins raised from the smooth skin of his forearms and those ridiculously thick eyelashes and that gorgeous cock. He was a lost cause. There was no doubt about that. All that remained of Finn in that moment was the intense, throbbing lust he felt for Blaine. And it was about to be sated.

Blaine leaned in closer, so close that Finn could smell his cologne and could have easily kissed him if he wanted to. But Blaine’s hand was disappearing low between his legs so all Finn could really do was hold his breath and wait for that initial contact.

“Relax,” Kurt’s voice said in his ear. Finn looked over at him. When had Kurt taken his clothes off?

“Kind of, uh, hard to do at the moment,” Finn said.

“Well try,” Kurt told him. “He’s excellent. Trust me.” Finn nodded and closed his eyes, willing his body to relax.

A warm and wet finger touched his asshole, prompting him to jump a little.

“Relax,” Kurt whispered, running a hand down his arm in a heavy stroke that was really nice and comforting. It could have been weird that Kurt was touching him when his boyfriend was rubbing little circles around Finn’s asshole but it wasn’t. It was a good thing and he knew that in that moment Kurt was probably keeping him from making a complete ass out of himself, so that was good.

The warm movements of Blaine’s fingers were actually nice. Finn hadn’t exactly spent any time down there when he was masturbating, so this was a completely new experience and well, he kind of understand why guys liked it. It felt good in a really different way than jerking off did, but it didn’t feel like enough. It was nice and all, but he knew that he wouldn’t be able to actually get off just from this alone.

“More,” he heard himself say, acutely aware of the giant disconnect between his brain and his mouth. Without a word, Blaine started pressing in ever so slightly until one of his fingers was inside.

Okay, that was new.

It didn’t feel bad. It was just different. Miles away from anything he’d ever felt before. But Kurt was still rubbing his arm and even though Finn wasn’t listening to anything other than the thudding of his own pulse in his ears, he knew that Kurt was whispering to him as Blaine continued to slide in until he couldn’t go any further.

“Are you okay?” Blaine asked.

“Uh… yeah,” Finn said, his eyes still clenched shut.

“I’m going to go slow while you get used to this and once you do, I’ll add another finger, okay?” Blaine asked. Finn nodded and breathed deeply, trying to continue to take Kurt’s advice and relax, although having something in his ass was making him kind of want to do the exact opposite.

Until Blaine slid in the second finger, that was.

Almost immediately, Blaine did something that made Finn see stars. Hot licks of pleasure shot straight to the tip of his dick and he was pretty sure that he screamed something really embarrassing. That theory was proven when he heard Kurt laughing beside him.

“I told you he was good,” Kurt practically purred, leaning in close. “Look at him. He does everything with so much… gusto.”

Finn peeked down at Blaine and both of his eyes immediately flew open wide. Blaine was biting on his bottom lip as he slid his fingers in and out of Finn’s ass, those jolts of pleasure coursing through Finn each time he started to pull them back out again. His arms were flexed, muscles standing out in clear definition as he worked with obvious restraint.

It was starting to feel really good, what Blaine was doing. It still was a little uncomfortable and the stretch was obviously new, but it wasn’t bad by itself and whatever he kept doing to make Finn practically see stars was somewhere in the realm of really fucking awesome.

Distantly, he heard Blaine ask Kurt for the lube but all he could really do was just lie there, his hips rocking with the rhythm of Blaine’s fingers and his mouth panting short breaths as he attempted to keep himself under control. He was pretty sure that he could come just from his. It felt that good.

Blaine added a third finger and coupled it by wrapping his other hand around Finn’s cock, stroking it back to full hardness as he moved both hands in perfect synchronicity.

“Oh fuck,” Finn grunted, his head slamming back against the arm of the couch as Blaine started just moving his fingers in the tiniest little rubbing movement, pressing against that spot that was making his toes curl into the leather.

“Prostates are amazing, aren’t they?” Kurt asked. Finn could only moan in response. “I think he’s ready, Blaine.”

“Yeah?” Blaine asked, not stopping the motion of his fingers and hand as he smiled at Kurt.

“Definitely,” Kurt nodded. “And so am I.”

“Get over here,” Blaine said with a grin, slowly sliding his fingers from Finn’s ass as Kurt stood and walked over, gasping and gripping onto Blaine’s shoulders as the head of his cock was sucked into Blaine’s mouth.

“You could warn me before you do that,” Kurt said, his tone affectionate in a way that would have made Finn feel kind of guilty had Blaine’s hand not still been working over his cock.

“What’s the fun in that?” Blaine asked, licking up the underside of Kurt’s cock, his tongue trailing over a thick vein. “Hand me a condom?”

“I’ll do you one better,” Kurt said. He took a condom from the same drawer the lube had come from earlier, ripped it open with his teeth-which was kind of weirdly hot, Finn had to admit-and rolled it over Blaine’s cock before coating it with lube. All the while, Blaine was still lightly stroking Finn’s cock, keeping him hard and occasionally sliding his thumb around in the precome beading at the tip.

“Thanks,” Blaine grinned, accepting a deep, open-mouthed kiss with so much tongue Finn could easily see it even through his admittedly lust-filled haze where little seemed to be properly working aside from his cock and his heart and the rush of his blood continuing to flow south.

“Anytime,” Kurt winked before once again sitting on the coffee table.

“Are you ready?” Blaine asked.

“Yes,” Finn gasped out as Blaine gave a more forceful tug on his cock.

“I’ll go slow,” Blaine told him, moving both hands to smooth over Finn’s hips before lining himself up.

The head of Blaine’s cock was thick and Finn made himself breathe deeply and focus on nothing other than Blaine’s strong hands rubbing at his hips and thumbing over his hipbones. Finn could feel Blaine shift, his knees digging into the cushion as he pushed forward until ohmygod his cock was in Finn’s ass.

With ridiculously tiny thrusts, Blaine worked his way in with self-restraint Finn knew he wouldn’t have been able to show if the roles had been reversed. When Finn felt Blaine’s balls press against his ass, he took a moment to really look at the man hovering over him.

For so long, Finn had been experiencing these incredibly confusing feelings for Blaine. The fact that they were based on pure sex was probably the most confusing thing of all. If he’d developed a crush, if he’d found himself craving coupley things with Blaine or wanting to spend every waking moment just being in his presence, then it might have been easier to deal with in the long run. But this, the lust he felt, was just so strange. Wanting Blaine the way he did was impossible to fit into his head. And even now that he was having him, it didn’t feel real.

There was no way that Blaine was fucking him right now. It just wasn’t possible. Finn was just having a really realistic dream. He’d had them a thousand times since this had all started and he was sure that they would continue even after this was over. Now that he knew how amazing Blaine looked naked-all dark hair and tight muscles and smooth skin-he was sure that his dreams would be taking on an entire new level of intensity.

Blaine’s skin was flushed, his bottom lip between his teeth as he held himself still, his eyebrows furrowed in concentration. He was beautiful.

Finn squirmed a little, needing Blaine to move. It was starting to feel uncomfortable the fullness coupled with stillness and he just needed something. As if on cue, Blaine slowly slid out before thrusting back in, angling his hips differently and stroking over that amazing spot again.

Oh yeah. That was definitely better.

“God, you’re so tight,” Blaine gritted out before sucking in another lungful of air. A low moan sounded from Finn’s left and he saw Kurt stroking his dick in long twisting strokes while cradling his balls in the other hand as he watched them.

As Blaine expertly thrust in stroke after stroke, Finn found himself growing accustomed to the feeling. Yeah, it felt good and all and his body had gotten used to the intrusion, but there was the fact that he had to fit into his brain. He was being fucked by Blaine. He was having sex with Blaine. Finally, after four years of wanting and dreaming and coming all over his fist with Blaine’s name on his lips, it was actually happening.

The friction of Blaine sliding in and out of him was kind of unbelievable and without even meaning to, he begged Blaine to go harder. Instead of complying, Blaine pulled out completely, Finn’s body immediately missing the feeling of being filled.

“What? No,” Finn said, the tone of his voice close to a whine as he reached for Blaine and managed to yank him down. Blaine fell awkwardly on top of him with an ‘Oof’ and a laugh. Blaine kissed him with tongues and teeth and moans until he was pretty sure he was actually melting into their couch.

“You need to get up on your knees,” Blaine said, lightly biting on Finn’s lower lip before pulling back.

“Why?” Finn asked, though he was already doing as told. Again, he would do pretty much whatever Blaine wanted him to as long as it meant Blaine would keep touching him. And letting Finn touch him.

“It’s time,” Blaine said.

“If you still want to,” Kurt added hurriedly. Finn looked back and forth between them as everything clicked back into place. Right. The both at the same time thing.

“I don’t think it’s going to work,” Finn said, shaking his head and trying to ignore the nervous thudding of his heart. “I mean, I don’t see how it-“

“We just have to take it really slowly,” Kurt said.

“But if you’re not comfortable with it, we won’t do it,” Blaine said.

If he was uncomfortable with it? Of course he was uncomfortable with it. They wanted to put both of their cocks in his ass at the same time. But then again, he hadn’t thought that he would have really liked being fingered or fucked but he so had, so how could he know for sure that he wouldn’t like this, too? He trusted them to go slowly and he’d told him that he would do this. So he would.

“I’m fine,” Finn said, rising up onto his knees and finding himself feeling strangely sore in ways that he really didn’t want to think about at the moment.

“Okay, so how this will work is-“ Kurt started but Finn waved him off.

“I don’t really want to know the details. I think I’ll get the gist. Just, go ahead,” he said, looking over to find Kurt rolling a condom onto himself before coating it with lube. Finn tried not to think about how huge Kurt’s cock was, because well, it was about to go in his ass and that just brought about a whole series of mental images that were making him do anything other than the relaxing he knew he needed to do.

Finn felt Kurt climb onto the couch behind him and place a hand on his shoulder at the same time that Kurt slid the head of his cock up and down Finn’s asscrack, spreading lube around and biting back a moan. When Finn felt something thick-thicker than Blaine’s cock had been-pressing at his entrance, he latched onto the back of the couch, his fingers death-gripping the leather as Blaine knelt in front of him, placing steadying hands on his hips.

“Hey, it’s okay. We’ve got you,” Blaine said, looking over Finn’s shoulder for a moment before leaning in to kiss Finn.

Finn allowed himself to get lost in the kiss. In the sweep of a tongue across his lips. In the taste of Blaine’s mouth. In the almost silent moan Blaine made when Finn sucked his tongue into his mouth.

When he felt Kurt push his hips up, the leather squeaking as his knees dug down to counter the movement, Finn’s mouth ripped away. He panted into Blaine’s shoulder, his fingers anchoring him on Blaine’s hips, subconsciously rubbing his thumbs over the soft skin that covered his lower abdomen. Kurt was barely even inside but oh my god.

He was already so stretched, so ready for this that it actually felt good. Kurt’s giant cock in his ass felt amazing. No longer did the stretch make him nervous. Now, he knew what was coming next-the bliss of friction and heat and those ohsoperfect slides over his prostate. Kurt didn’t bottom out. He probably couldn’t, Finn realized, given their positioning and the fact that despite Kurt’s multiple growth spurts, Finn still had a good six inches on him. Height-wise. In other types of measure, Kurt definitely had him beat. By a lot.

“We’re going to move now,” Kurt said in his ear, his breath hot and his voice lower than Finn had ever heard it before. “I’m going to sit down and you’re going to come with me.”

“Okay,” Finn managed to croak out.

He was lucky to have even done that, given the fact that Kurt was slowly thrusting as he spoke. Okay yeah, Blaine had been right. It did fit and it was awesome. Also awesome was the fact that through all of this, Blaine was still kneeling in front of him, stroking his own cock and biting his lip again. God, Finn wished he’d never learned that Blaine did that during sex because honestly, it was going to have a leading role in all of his fantasies from now on.

Kurt slid his left arm around Finn’s chest, his hand pressing in as he slowly lowered himself back against the arm of the couch. With Blaine’s help to keep Finn steady, they got settled in with their legs stretched out on the couch in front of them, Kurt’s resting inside of Finn’s and Finn pretty much just lying back on Kurt’s chest. The angle wasn’t the best, but it still felt good.

“He feels amazing, doesn’t he?” Blaine asked, smoothing one hand up the inside of Kurt’s legs before running them back down the outside of Finn’s.

“Yes,” Kurt said, his voice tight and controlled.
“Are you okay?” Finn asked, tilting his head to the side even though he still couldn’t see Kurt’s face when he did it.

“Definitely,” Kurt said with a little laugh. “Sixteen year old me is doing high-kicks right now.”

Finn didn’t have time to react to that because Blaine was dropping down on his stomach, licking his lips as he stared ahead. Clearly, he was looking at the way Kurt was shallowly thrusting into Finn’s ass and apparently he was enjoying what he saw. He reached forward and trailed his finger in the lube around Finn’s asshole where it was stretched to accommodate Kurt’s cock.

“Are you ready?” Kurt asked, the hand still pressed into Finn’s chest practically shaking as his hips kept rhythmically moving.
“Fuck yes,” Blaine said, diving in and licking the same path his finger had just laid. His tongue was hot and wet and Finn cried out as a tidal wave of heat and pleasure shuddered through his body. Kurt clung to him, his nose pressing into Finn’s neck and Finn realized that Kurt could feel Blaine’s tongue, too. And then he remembered what Kurt had told him earlier-that when Blaine would be fucking Finn, he’d be fucking Kurt, too. Now he got it.

When Blaine had apparently licked to his heart’s content, he drug his tongue up and over Finn’s balls, sucked his way up Finn’s cock with wet, open-mouthed kisses, and then swirled his tongue over the head before sliding further over Finn’s body. He kissed Finn and then leaned far over his shoulder to kiss Kurt before Finn felt the pressure of Blaine’s cock dragging around his asshole.

“Relax,” Kurt whispered, biting down lightly on Finn’s earlobe for a moment before sucking in a quick breath and pulling away. “I’m sorry.”

“It’s fine. You can do whatever you want,” Finn said and he meant it.

They’d already gone this far. Kurt’s cock was in his ass, so what in the hell did a little ear biting matter? Kurt practically growled, the vibration of it rumbling through Finn’s back as he felt Kurt’s mouth latch onto the side of his neck, sucking and licking as he thrust in such little movements that Finn could do nothing to counter the action. All he could do was lay there and take it.

He vaguely heard the sound of the bottle of lube being opened and he could feel Blaine hovering over him, but the slow pleasurable heat Kurt’s cock was rocking inside of him was more than he could handle at the moment. He wanted to squirm and buck and thrash but knew that he couldn’t because he would fall off of Kurt’s lap and then he would knock Blaine onto the floor and that was just the opposite of what he needed at the moment. He needed to come and awkward flailing wouldn’t lead to that.

“Relax,” Kurt said as his hand trailed down from Finn’s chest to wrap around his cock.

Blaine focused his movements to one point, what was visible of his bottom lip turning practically white from the pressure his teeth were exerting on it as his hips rolled in. His stomach was tense, his abs looking phenomenal and pornographic as he pressed hard against Finn’s asshole.

This wasn’t going to work. There was no way. There was already a huge cock in his ass so how could-

But then Blaine was in. Finn felt the head of his cock slide through and all three of them simultaneously sucked in a deep breath,. Everything felt so… present. Their cocks were pressed together inside of him, filling him so much that Blaine was pressed right against his prostate. It was taking all of Finn’s restraint not to move, but he didn’t trust it to hold. He was seconds away from breaking-from bucking and moaning and coming all over all of them.
“Oh my god, I’m not going to last long,” Blaine finally said, the first to break the silence as the words spilled out of his mouth along with a huge rushing breath.

“Me either,” Kurt moaned, his breath hot against Finn’s ear as he kept up the movement of his hand on Finn’s cock. If he’d been able to properly use the English language in that moment, Finn would’ve added that he didn’t think he’d be lasting long either, but he couldn’t. So, he just tried to keep still as Blaine continued to push in.

There wasn’t a sound in the room aside from their heaving breaths, each of them the picture of control as they got used to the brand new and incredibly intense sensation. Sweat was collecting along Blaine’s hairline, his jaw slack, tendons in his neck taut as he continued to brace himself with his hands digging into the black leather beside Finn’s ribs-well, both of their ribs. When he breathed, it sounded like it was taking every single ounce of effort he had in order to fill and empty his lungs. Finally, he was in all the way and he ducked down to press his forehead against Finn’s chest.

“Are you okay?” Finn asked.

“Oh my god yes,” Blaine laughed breathlessly. “I just need a second.”

“Don’t take too long. I need you to move,” Kurt said through his teeth, his hand still working Finn’s cock.

It was a really freaking good handjob. Probably the best Finn had ever gotten. Each stroke of Kurt’s hand twisted and tugged, his thumb sliding over the tip every so often smearing around precome. Finn really wanted to come.
His balls felt tight and they ached a little and the heat in his groin was almost overwhelming. And just knowing that their cocks were not only inside of him but also rubbing against each other added a whole new level to the hotness of it all. He wasn’t sure why, but it did.

“Okay,” Blaine finally said, lifting his head and letting his hips lead the way until just the head of his cock was still inside.

“Fuck,” Kurt grunted against his neck before sucking hard again. Finn was definitely going to have a hickey there in the morning and he so didn’t care.

“This feels so good,” Blaine panted as he pushed back in, each millimeter of movement rubbing Finn’s prostate and making him forget how to do very basic things like speak and breathe and not make pathetic whimpering sounds every five seconds. Finn wanted Blaine to go faster. He didn’t know how his body could possibly want that when he was already stretched so far, but his ass was being surprisingly accommodating. Something told him that he could take an increase in speed.

”Can you go just a little faster?” Kurt asked, that level of control returned to his voice as he started jerking Finn off more rapidly. Finn didn’t know when Kurt had become a mind-reader, but he was more than happy with the development. Blaine nodded and started moving just a bit quicker, each thrust now punctuated with a little grunt. It was the hottest thing Finn had ever heard in his entire life.

Finn felt his balls draw up even tighter, the familiar feeling of hot pleasure twisting in his stomach and making his hips surge. Kurt cried out as Finn shifted, stroking his cock even faster and Kurt’s hips give a little thrust, too.

“You have to hold still, babe,” Blaine gritted out.

His chest looked damp and Finn wanted to trail his tongue over the wet skin, taste the saltiness as he flicked his tongue over one of Blaine’s nipples, but there wasn’t time for that. He was overwhelmed with sensations enough as it was. Adding taste to the mix would probably only serve to actually make him die from pleasure. What a way to go, though.

One more perfect thrust from Blaine sent Finn over the edge. It felt like he was falling off a cliff-the air rushed from his lungs as he shouted out something vaguely coherent and entirely obscene and he grabbed hard onto Blaine’s shoulders to keep himself from sliding sideways off of Kurt’s now sweaty chest and stomach.

“Oh my fucking god,” Kurt cried out, stroking Finn through his orgasm as Blaine started to thrust harder. Faster. It was too much. Finn just kept coming, his cock pulsing streak after streak of come all over Kurt’s fist and his stomach and Blaine’s stomach and god, Finn really wanted to look and see what a wonderful mess he’d made but he couldn’t. All he could see were neon stars on a blackened canvas as his eyes squeezed shut so hard he wasn’t sure he’d ever be able to open them again.

Blaine was trying to force his thrusts down and away from Finn’s prostate, but the thickness of their cocks combined was making that impossible. Finn’s hips were moving all on their own, squirming and stuttering as his cock softened. Dragging come across his stomach, Kurt moved his hands to Finn’s hips, grabbing on hard as Blaine fucked them both so hard Finn was pretty sure he was going to get hard and come again before either of them managed to do so once.

But then Kurt was moaning and Blaine was moaning and all Finn could feel was the steady beat of pulsing cocks and balls and the sweat sticky feeling of their chests against him. There might have been hands touching him and they might have been talking to him, but he was completely unaware. Everything felt warm and calm and part of him that had been tense for so long was just… relaxed.

“Thank you,” Kurt whispered, the words ending in a moan as Blaine slipped from Finn’s ass.

“You were great,” Blaine told him, pressing a kiss to his cheek. Finn turned his head, hoping to capture his lips again, but Blaine was turning and sliding off the couch. As Finn took Blaine’s hand to help him off of Kurt’s cock, he tried to ignore the ache in his chest.

Now that everything was over, Finn felt weird. He was naked and covered in come and he’d just had sex with his step-brother and Blaine. All he’d wanted to do when he’d come to the city was visit Yankee Stadium, eat at Grey’s Papaya, and steal some glances of Blaine’s ass for the first time in months. This… was beyond anything he ever could have hoped for.

“Uh, thanks. So were you. Both of you,” Finn was quick to add as he stood. Blaine and Kurt both smiled, each of them looking more happy and sated and, well, sweaty and wrecked than he’d ever seen them look before. Hell, Blaine was even managing to look more so than he had in any of Finn’s fantasies. “I think I’ll go take a shower.”

“That sounds good. We’ll get in when you’re finished,” Kurt said with a nod as Blaine climbed onto the couch beside him, pressing a kiss to his neck before settling his head in on Kurt’s shoulder. Finn took one more look at Blaine, submitting the image to memory before walking toward their bathroom, trying not to be self-conscious about his nudity because well, they’d all just had sex together and what was the point in that.

“I love you so much,” Finn heard Blaine whisper to Kurt just as he stepped into the hallway. The ache in his chest throbbed harder as he stepped beneath the scalding spray. He didn’t know what it was, because he definitely wasn’t jealous.

He’d just gotten everything he’d ever wanted from Blaine-sex and kisses and glimpses at what he looked like in his purest, most perfectly aroused moments-so there was nothing to be jealous of. Blaine wasn’t his and never would be. Not that he even wanted Blaine to be. Because it was just about sex.

No, he definitely wasn’t jealous.

Definitely not.
