Kurt couldn’t figure it out. He hated Sebastian Smythe. He couldn’t stand this arrogant, egotistical, meerkat of a man who’d spent weeks trying to steal Blaine away from him. He hated Sebastian Smythe. He hated how this flirty little shit kept looking at his boyfriend, smiling that cocky, sideways grin. How he rolled his hips and snaked over to Blaine at every opportunity during the damn Jackson 5 song that didn’t even make sense, given the context.
If Kurt wasn’t trying to maintain his dignity, he would have gladly interrupted the performance to kindly tell Sebastian to go fuck himself. Maybe it’ll soothe some of your desperate lusting after my boyfriend.
But Kurt didn’t tell Sebastian Smythe to go fuck himself.
In fact, as the song came to an end and Sebastian only continued to mock and jeer with that damn cocky grin, Kurt found himself wanting to take matters into his own hands. He could fuck this little high school movie villain wannabe and wipe that grin straight off his face. He could make Sebastian squirm and scream until he never even thought to glance at Blaine ever again…
“A threesome?” Blaine’s eyebrows flew up in shock when Kurt shared his idea the following day in the McKinley parking lot. “You want to have a threesome with Sebastian? Who are you and what have you done with my boyfriend?”
“Shut up,” Kurt rolled his eyes, smirking, “I just want to show that jerk he can’t have you, and that I’m more than capable of keeping you wrapped around my finger, no matter how hard he tries to seduce you. You’re my beautiful boyfriend,” Kurt wrapped an arm around Blaine’s waist as they walked, “Not his.”
“Mmm, I like it when you’re possessive,” Blaine said, voice a bit lower than before, “Maybe we shouldn’t have the threesome… Then Sebastian won’t lighten up, and I’ll get to see more of you being territorial.”
“If we have a threesome, you will see plenty of me being territorial,” Kurt assured, “and I’ll be naked at the same time—”
“Let’s do it.”
Kurt laughed. “You sure?”
“Yeah. I mean…” Blaine’s voice grew quiet, “don’t take this wrong way, but… Sebastian is really rather attractive.”
“I’ve noticed,” Kurt grumbled in frustration, then after a moment, “So we’re really going to do this?”
“I’m game if you are.”
“Let’s call the meerkat and get him on board.” Blaine pulled out his phone and dialed the Warbler’s number.
Of course, Sebastian immediately agreed.
After the arrangements were made, Kurt and Blaine found themselves on the front porch of the Smythe residence on Saturday evening. Dressed in casual outfits, any passing car would never imagine the sexual shenanigans they were about to partake in.
Kurt rang the doorbell. Sebastian arrived to open it less than twenty seconds later and ushered them inside with that same cheeky grin Kurt couldn’t wait to see replaced with a jaw dropped in a silent scream of pleasure.
“Evening, boys,” Sebastian greeted, sliding up next to Blaine. A hand that was most definitely not Kurt’s own slid around Blaine’s shoulders. “Hey, Blaine.” Kurt shot him a glare.
“I know my boyfriend is irresistible, but at least wait ‘til we get to your bedroom, will you?” he hissed.
“Jealous, Hummel?” Sebastian teased. “Don’t worry. I’m sure Blaine and I can fit you somewhere in the mix tonight.”
Kurt rolled his eyes. Let’s hope you can fit me in, Sebastard.
The moment they were behind Sebastian’s closed door, the Warbler pounced, pinning Blaine to the wall. “I’ve been waiting to do this for weeks, killer,” he breathed. Blaine shot a glance at Kurt, who gave a slight nod of his head, assuring him that he was okay with it. They weren’t cheating. They were just… sharing.
Sebastian leaned in and captured Blaine’s lips hungrily. Kurt watched, feeling his cock twitch in his pants at the sight. Two gorgeous boys—one he loved, one he couldn’t stand—kissing each other heatedly. It wasn’t romantic, and it certainly wasn’t something he’d want to see very often, but it was admittedly incredibly sexy in the moment.
They kissed for a long minute, Sebastian pressing Blaine heavily against the wall, practically smothering his body with his own. Blaine looked small against the Warbler’s stature, but he was holding his own in the kiss, pushing back against Sebastian’s lips with surprising force. When Blaine moaned, Kurt moved to intervene. He stepped close to the pair and took both of their hands, tugging them toward the bed a few feet away.
They collapsed onto the mattress in a fumble of limbs, none of them really sure who or what they were grabbing at for a few seconds. Then Blaine’s lips were on Kurt’s, and Sebastian was watching, breathing harder than usual as the two lovers lost themselves in each other’s touch. He decided to help them out, and while the two continued kissing, Sebastian went to work at the buttons on Kurt’s shirts. Really, couldn’t Hummel have worn something that wasn’t so damn complicated to get off?
Kurt finally noticed someone tugging at his clothes, and he pulled away from Blaine with a wet sound, leaning back to let Sebastian reach the last few buttons. Sebastian undid the last one and parted the navy colored halves, revealing Kurt’s pale chest and stomach. They froze for a moment, staring each other down, and then Sebastian tugged the sleeves down Kurt’s arms, pulling the shirt off and tossing it to the floor without a glance, daring Kurt to get angry about the inevitable wrinkles the fabric would be riddled with.
Kurt’s eyes narrowed. He sat back up and reached for the hem of Sebastian’s white tank, pulling it up over his head and discarding it with the same lack of care. Blaine watched the exchange with an uncertain expression— the tension practically tangible in the air—half expecting one of them to throw a punch. Kurt was the first to break eye contact, turning back to his boyfriend and removing his shirt with much more gentle movements. As he tugged it up, revealing Blaine’s torso, Kurt pressed kisses to his skin, following a path all the way up until their lips met again for a chaste peck. Blaine smiled, his eyes sparkling with affection, and Sebastian felt jealously and desire curl in the pit of his stomach.
“We’re gonna have to get more than our shirts off if we want to make any progress, gentlemen,” he reminded coolly.
Kurt raised an eyebrow but nodded in agreement, reaching for the zipper of Blaine’s jeans without comment. Blaine quickly lifted his hips off the bed to help Kurt slide them down his legs. Impatient to get started, Sebastian climbed off the mattress and shed his own, along with his underwear, pooling them at his ankles before rejoining the couple on the bed, fisting a hand around his hardening length and giving himself a few impatient strokes as he waited for the lovebirds to finish undressing.
Finally, all three of them were bared and exposed to each other. Six eyes began to wander over three handsome bodies, raking over muscles and staring at three, perfectly unique, beautiful erections, arching up toward their stomachs. Blaine cracked a smile, eyes a shade darker than normal as he considered all the possibilities.
“So,” he broke the silence, sounding rather relaxed in the face of such a daunting sexual experience, “Who’s doing what?”
“I’m doing you.” Sebastian’s answer was immediate. Kurt didn’t even need to look at his face to know that same shit-eating grin was on his face. Again, Blaine glanced toward Kurt, like he still wasn’t sure this wasn’t breaking any of their rules. One corner of Kurt’s lips turned up into an affectionate smile, and he crawled closer to kiss Blaine slowly, hands on his boyfriend’s face.
“Just enjoy it, Blaine,” he said, “I told you I was fine with this. It was my idea, remember?”
“Love you,” Blaine murmured.
They pulled apart again and Sebastian moved in, immediately zeroing in on Blaine’s neck. Kurt felt a possessive frustration build inside him as he watched this other mark his boyfriend with hickeys. He couldn’t help the instinctual response, but he could fortunately keep it under control, reminding himself that they’d all agreed to this. It wasn’t cheating. It wasn’t assault. It was consensual; just something new.
Things progressed quickly. Soon, Blaine was on his back, a pillow beneath his hips, and his ass being stretched by Sebastian Smythe’s nimble fingers. Kurt had half a mind to look away, the sight was so bizarre, but he couldn’t keep from staring at the way Blaine’s ass clenched around those fingers as Sebastian drew them in and out, flexing, scissoring and twisting them to sweep over Blaine’s prostate.
When Sebastian removed his fingers and spread a generous amount of lube over the condom rolled down his length, Kurt was oddly perplexed. Seeing another man slide his cock into Blaine’s entrance was so erotic Kurt was almost ashamed with himself. It was like porn, only Blaine was one of the stars, and the moans falling from his lips weren’t fake.
Sebastian set up a slow pace, letting Blaine adjust, and Kurt watched, barely noticing when he reached to pump his hand along his own erection in time with Sebastian’s thrusts. He snapped out of it a few moments later, not wanting to orgasm before he’d even got in on any of the touching. Sebastian would never let him live that down. Moving from where he kneeled on the bed, Kurt lowered himself down beside Blaine, tilting his boyfriend’s head to the side so he could kiss his breath away—or what was left of his breath, anyway. His hands teased over Blaine’s body, pinching at his nipples, sliding down his burning skin, and fondling gently with his cock and balls underneath.
“Fuck, Hummel,” Sebastian gasped out over Blaine’s groans, never pausing his movements, “You just can’t leave him alone can you?”
“What?” Kurt shot back, “You want some attention, too, Smythe?”
Sebastian laughed, “You wish.”
Kurt rolled his eyes and refocused on Blaine, who’d began mumbling a string of words that Kurt couldn’t quite make out. “What is it, honey?” Kurt asked.
“I want you,” Blaine breathed, letting out a cry as Sebastian hit his prostate and scrambled his thoughts, “Wanna suck you off. Want you both in me.”
A wave of heat rushed over Kurt’s skin at the thought, and he didn’t have to consider his options before sitting up and straddling himself over Blaine’s chest. He supported Blaine’s head and held it up so he could reach. Blaine’s hand slipped around Kurt’s abdomen and took hold of Kurt’s cock, guiding it into his mouth with practiced ease. Kurt groaned at the familiar wet heat of his boyfriend’s mouth.
Even with the onslaught of Sebastian fucking him, Blaine was able to retain enough control to give Kurt an amazing blowjob. He sucked eagerly, still grunting as Sebastian pounded into him, but never losing concentration.
“You’re blocking my view, Hummel,” Sebastian hissed, “I didn’t agree to this so I could stare at your back.”
Kurt ignored him. He stayed in his place over Blaine’s body for another minute before gently pulling out. Blaine moaned in protest. “Come back,” he reached out with a hand, gripping Kurt’s forearm as his boyfriend slid back onto the mattress, his cock slick with saliva and precome.
“Shh,” Kurt hushed him, “You’re too good at it, Blaine. You’d have me boneless in another thirty seconds if I hadn’t pulled out.”
“And what? You wouldn’t be able to get it back up then?” Sebastian asked with a chuckle.
“Not for you,” Kurt lied.
Sebastian licked his lips and shook his head, not bothering to respond. His breaths were getting shaky now, and he was letting out a few groans of pleasure from time to time. Blaine’s eyes were squeezed shut, moans falling freely from behind his lips. They were both close. Kurt wrapped his hand around Blaine’s cock and gave him a few quick strokes. His boyfriend’s hips jerked as he spilled over Kurt’s hand, and the change in angle had Sebastian cursing up a storm as he followed the way into orgasm.
There were a few minutes of rest afterward, Sebastian and Blaine both panting. Kurt wiped his hand off on the sheets, glad they weren’t doing this in his bed. When Sebastian slid out of Blaine, Kurt watched him peel off the condom and toss it into the nearby trashcan. Kurt reached for another on the nightstand and tore open the foil package with determination.
“Don’t you think you should wait?” Sebastian asked, “I think your boyfriend’s pretty royally fucked right now.”
Kurt let out an indignant snort of amusement, “I’m not doing this with him,” he said.
It took Sebastian a moment to understand what Kurt was getting at. “No way, Hummel.”
“You agreed to the arrangement,” Kurt reminded.
“I agreed so I could finally get into Blaine’s pants. I never agreed to anything about letting you fuck me.”
“Seb,” Blaine interrupted, “Let him do it.”
“Shut up, Blaine. Take a nap or something.”
“It’s not like you’re gonna get yours up again in the next two seconds anyway,” Blaine remarked, gesturing to the flaccid cock between Sebastian’s legs. “We’re wasting time if we just sit here.”
“You suck, Anderson.”
“Yeah, I’m lucky. I get to suck Kurt quite often.” Kurt gave him a playful slap and Blaine held his hands up in defense, eyes still half-lidded and tired as he floated down from bliss.
“Fine,” Sebastian acquiesced with a grumble. “But we aren’t doing missionary. If I have to look at you, I might start laughing, and that could kill the mood, huh?” he mocked.
“Just get on your hands and knees before I strangle you.”
“Shit, Hummel. I didn’t know you were so kinky.”
Kurt bit his tongue, refusing to let himself get into another verbal sparring match. That was definitely not the point of this evening. Now that Sebastian had given him permission, Kurt would fuck the living daylights out of him, and with any luck, this asshole would feel it for weeks.
He didn’t waste any time, slicking up his fingers and sliding two past the ring of muscles without a word of warning. Sebastian hissed but made no other reaction as Kurt prepared him. Though Kurt wanted to make Smythe a writhing, incoherent mess by the end of it, he didn’t want it to happen out of pain, so he was careful to be thorough, stretching Sebastian just as attentively as he would Blaine.
When he lined up his cock at Sebastian’s entrance, Kurt hesitated for a second or two, wondering if he was making the right choice. But then he caught sight of Blaine, still laying back on the bed, watching with eager eyes. Sebastian had already fucked his boyfriend. If he changed his mind now, Blaine would probably feel guilty, and Sebastian would never, ever let this go. So Kurt pushed in, clutching at Sebastian’s hips for support as he moved in closer.
As soon as he was fully sheathed, Kurt pulled back, dragging himself backward until only the tip of his cock was out of sight. He repeated the process a few times before picking up speed, and he could feel Sebastian’s muscles shifting and clenching beneath his hands and around his sensitive flesh, though he made no comment.
It soon became clear to all three boys in the bed that this was a lot more than just a simple fuck for pleasure. Kurt and Sebastian were competing, like a game of chicken—a very erotic game of chicken. Waiting to see who would crack first. Kurt picked up speed quickly, and even when he set a pace that would have had Blaine crying out beneath him, Sebastian only panted for breath and rolled his shoulders to keep them from getting sore.
Kurt glared and pulled out, blinking hard at the loss of friction. A flicker of satisfaction registered in his brain as he watched Sebastian’s ass clench—the only sign that he missed the feeling. “Turn over, Seb,” Kurt told him.
“Why the hell would I do that?”
“Because we’re not getting shit out of this position and we both know it. Turn over.”
Sighing in frustration, Sebastian moved. Blaine pulled the pillow out from underneath his hips and pushed it over for Sebastian, who reluctantly laid back against the mattress and spread his legs, reaching down to stroke himself with a bored expression. “Maybe it’s not the position. Maybe you just suck at this, Hummel,” he shrugged.
“We’ll see about that.” Kurt moved into position and pushed back into Sebastian’s body a second later. He thrust forward with a sudden, powerful jerk of his hips, and Sebastian finally let out a half-stifled groan as Kurt hit his prostate. The Warbler glared. Kurt shrugged a single shoulder and continued.
The new position was definitely better, at least for Kurt. He hit Sebastian’s prostate more often than not, and though Seb put up a good fight to swallow every sound before he made it, Kurt could see his muscles quivering with effort, sweat beading on his forehead. He was really quite sexy like this, sprawled out on the bed. Ew. No. Kurt silenced his thoughts and thrust harder, digging his nails into Sebastian’s side as he tried to focus on the physical.
“Just fucking kiss me, Hummel,” Sebastian spat.
“You’ve been staring at my lips for two minutes straight. Fucking kiss me already.”
Kurt hadn’t even realized it, but at this point, he didn’t really care to argue. Sebastian spread his legs a little further as Kurt leaned down. Blaine slid in behind Sebastian to help hold him up, and their lips met for the first time. Sebastian’s were just as smooth as his own and Blaine’s—thank god he moisturizes—but he kissed roughly. Immediately, Kurt felt teeth nipping at his lower lip, and he fought back by forcing his tongue into the heat of Sebastian’s mouth. It got increasingly sloppy and hot and dirty as they continued, trying to outdo one another. Kurt pulled at Sebastian’s hair, tilting his head back and deepening the kiss further. Finally, Sebastian turned his head, pulling away to gasp for breath, and Kurt relished in the small triumph.
“Asshole,” the Warbler gasped.
Behind Sebastian, still propping him up against his chest, Blaine’s jaw was hanging open. “Holy fuck,” he whispered, “That was hot.”
Kurt couldn’t think of a reply, so he let the statement hang in the air as he pounded his hips forward again, rocking into Sebastian’s body with a force that the Warbler was not prepared for. Sebastian groaned, loud and long, and Kurt caught his lips again, cutting him off while he had the upper hand. He fucked the other teen mercilessly now, trying with all his might to hit Sebastian’s prostate with every pass. He could feel the vibrations of Sebastian’s moans against his body, and hear the garbled remnants of their sound in between demanding kisses.
Kurt relocated to Sebastian’s neck, biting down a little harder than he probably should on the sensitive skin. He licked over each spot, swirling his tongue with purpose to cover the marks and soothe the sting. Slowly, Sebastian began to succumb, and Kurt could feel him relax into the pleasure, accepting the defeat of their battle for dominance. It shot adrenaline through Kurt’s veins, and he wrapped a hand around the back of Blaine’s neck, urging him closer until he could press their lips together. Blaine whimpered brokenly into the kiss, his own hand pumping so fast and firm around his length that it almost hurt.
Suddenly, Sebastian was coming with a shout, his chest and stomach heaving. Kurt hadn’t even touched Seb’s cock yet. He knew for a fact that Blaine had been too occupied with his own to bother. He smiled to himself, holding out as long as he could before giving in to his own orgasm, hips giving a few stuttering jerks as he released into the condom.
Kurt pulled out immediately, still lightheaded and dizzy as he discarded the condom and collapsed onto the bed beside his boyfriend and his… well… beside his boyfriend and Sebastian. Everything was quiet for several minutes while they collected their thoughts. Kurt reached out and lazily threaded his and Blaine’s fingers together, idly wondering if his boyfriend would mind giving him another blowjob before the night was over…
“Better than I thought, Hummel,” Sebastian broke the silence.
“You too,” Kurt replied, “How’s your ass feeling?”
“Fucked,” Sebastian laughed weakly.
Kurt smirked. “That was the plan.”
“God, I hate you.” Sebastian propped himself up on an elbow and gave Kurt a glaring smile.
“Hate you, too.” Kurt placed his free hand on Sebastian’s shoulder and lifted his head up, closing the distance between their lips.
