Matthew woke far too early on one of their rare free days to the familiar sensation of something blunt pressing into his lower back.

He shifted slightly to hear a small hiss in his ear and the arms around his waist tightening.

“Gyuvin ah…” He whined quietly, sleep still heavy on his mind.

“Hyung,” A breathy whisper replied, the blunt mass moved to slip against his clothed ass.

Matthew felt the familiar bubbling want in the pit of his stomach, but it was too early for this, his mind was barely conscious.

He turned his head to face the boy pressed against his back, his barely open eyes locking with the wide and eager, gaze of his sort-of-kind-of boyfriend, Kim Gyuvin.

“It’s so early puppy.” He grumbled, letting the younger press a soft kiss against each of his eyelids and then the tip of his nose.

“Hyung, you don’t have to do anything… I just… I need you…” Gyuvin breathed against his lips.

Matthew sighed but he couldn’t stop the small smile from blossoming on his face. This was only a recent agreement. Their situation. But they had agreed to be non-exclusive with no jealousy that would get in the way of the group. He thought the younger would get sick of him quickly, Gyuvin was never one to stick with one obsession for too long, but Matthew was pretty sure in the past few weeks his bandmate had rejected three Inkigayo sandwiches and a potential date to spend the night in with him.

He was not going to let himself read into that.

“Okay, but I’m not moving… if I fall asleep, I fall asleep… just don’t make a mess like last time.” He grumbled and rolled over to lie on his front, letting the other boy throw a leg over his waist and move his body to cover most of his body, chest pressing down on Matthew’s back.

“I promise, hyung,” Gyuvin’s voice tickled his ear as the younger inhaled his scent, nose pressed against the back of his head.

He felt large hands fumble to push his pants down just below his ass and slowly pull his plump cheeks apart. A finger rubbed circles against his hole, the tip of it dipping in just enough to send a shiver down the older boy’s spine.

“God, you’re so perfect, hyung, you’re still stretched for me.” Gyuvin panted, licking a stripe on the soft skin behind Matthew’s ear.

Yeah, you almost broke my ass last night… how are you hard again so fast after four rounds? He thought faintly as he felt the moist head of his cock breach him once again. Gyuvin sunk in easily, letting out a haggard breath as he plunged into his favourite wet hole.

At the hilt, Gyuvin’s cock was so deep and heavy inside him that the outline was visible on his smooth abdomen. Even in his half-asleep state, the sensation of being so full made his toes curl. The younger wasted no time in beginning to thrust, his lips suckling at the juncture between his hyung’s shoulder and neck. He could feel his pulse against his tongue.

Matthew on the other hand felt his consciousness leave him as sleep beckoned him once again. He knew his puppy would look after him… besides something about waking up already aching from being fucked into his mattress… did something to him on a primal level.

.X.

The next time he woke, he was on his side again. Gyuvin was curled around him, every part of their bodies pressed against one another.

As he blinked away the sleep, he realised the heavy fullness in his abdomen was still there and so was the tight stretch of his hole around Gyuvin’s hard cock. He glanced down to see the younger caressing his slightly distended belly with his large hands.

He could feel his own dick twitch at the sensation. He suddenly felt the need to clench his thighs together.

Why is that so hot?

“Gyu?” He said, voice coming out croaky.

“Yeah, baby?” Gyuvin’s voice was right in his ear, lips brushing at his lobe as he spoke.

“You didn’t pull out?”

“I couldn’t bring myself to, I know how much you like being full, anyway, hyung,” Gyuvin spoke while grinding his hips against Matthew’s ass, his cockhead brushing against the elder’s already abused bundle of nerves.

A whimper rang out of Matthew’s mouth before he could stop himself.

“Sweet baby, Matthew hyung… you always need something in you… something to swell your little belly up all nice and round.” Gyuvin muttered, gently pressing his fingers against the swollen abdomen.

“Gyu, wait, wait!” He hissed quietly as the waves of pleasure shot through him far too fast and his length began to harden.

“You know what I think, hyungie?” Gyuvin continued his ministrations, rubbing at the spot directly above where his cock rested. Matthew was beginning to shake, fully hard now. He was so full he wanted more, the pressure on his stomach was getting too much.

“W-what?” He managed to utter, his hands grasping onto the younger boy’s much larger ones.

“I think you might be too used to my dick… I think you need something more to fill you up. Another cock for my hungry hyung’s hole, how’s that?” Gyuvin spoke the filthy words as he moved one of his hands down to ghost over the dribbling tip of Matthew’s dick.

“Ah!” Matthew came so quickly that he turned red with embarrassment, hands flying to cover his face.

The younger let out a soft laugh, “Hyungie, don’t be embarrassed!” He rained kisses on the side of his face and against his nape. “Fuck, you’re so cute.”

The pullout was always messy and a little sticky, but the younger had become a pro at it, he always had a towel on hand and his touches were as gentle as they were efficient. He had them both presentable in less than ten minutes.

“I meant what I said, by the way,” Gyuvin spoke as he helped Matthew pull on a pair of joggers, as the elder still had jelly legs from the night and morning of almost constant sex.

“About?”

“About maybe having a threesome?”

Matthew couldn’t help the frown that appeared on his face. Was he not enough? Not that he had a right to think that way, given their non-exclusive status.

The younger picked up immediately, eyes widening and arms flying up to explain.

“No! I mean, not just for me, I would be happy to live with you on my cock for the rest of my life. I mean, I see the way you look at Gunwook sometimes and it would be a lie to say I didn’t think he was hot too.” Gyuvin explained, “and it would be even hotter to see him fuck you.”

Matthew paused at that.

“And how exactly do I look at Gunwook?”

“Like you want to climb him like a tree then have him plow you like a field.”

“OH MY GOD. GYUVIN STOP,” He squeals in embarrassment at the younger boy’s far too accurate assessment of him.

Gyuvin cackled like a Disney villain and pulled his hyung against his chest.

“You are too cute; I’m going to talk to him.”

Matthew couldn’t find it in himself to argue. Gunwook was attractive, more so every day. He was pretty sure seeing him in that tight black T-shirt during their latest fansign almost broke his brain, he almost came there and then.

And if Gyuvin agreed too… well, who was he to refuse?

.X.

Matthew forgets about their conversation over the next couple of weeks. The exhaustion of a packed schedule wears on all of them and he can barely find a moment to rest, let alone think about sex.

Gyuvin was beside him as always, the younger boy a beacon of excitable energy keeping him sane when he thought he couldn’t go on. Gunwook was there too. The other boy always had time for him, but it seemed like he was more tactile now than he ever was. His huge hands always found Matthew’s hips, big fingers tracing lines in his thighs when they sat next to each other and there were moments when he threw an arm around his shoulders and pulled him into his side, making him feel tiny.

God. Matthew was losing any patience he had.

Gunwook was so big. So, fucking big. His hands wrapped around his tiny fists with ease. Matthew could only imagine what he was hiding in his pants.

He wanted it. He wanted it inside him.

To break him in half. Plough his insides and create a path of his own embedded in his guts.

He shook his head, snapping himself out of his filthy thoughts.

He tried to focus on what was going on around him. His various members played around in the breakroom; it was their last schedule for the next week. They were getting a well-deserved break, and everyone was hoping they would finish early so they could get some dinner before going back to the dorm. He watched Gyuvin playfighting with Gunwook, the two giants tussled, throwing each other around.

That insatiable feeling began to bubble inside him again- god, what would it be like to have both of them? At the same time. His mind supplied unhelpfully.

His fingers slipped under his baggy hoodie, palm pressing against his abdomen.

He would be so full.

Fuck. He squeezed his thighs together. He couldn’t get hard here.

“Hyungie,” A voice in his ear made him jump, he tried to play off his sinful thoughts shaking his head.

Gyuvin was suddenly beside him, Gunwook sliding over to sit on his other side sandwiching him in on the bench.

“Wha-” He cleared his throat nervously, “what’s up guys?”

The two puppies exchanged sly glances before slipping their own hands under their hyung’s hoodie.

“I’m in.” Gunwook whispered in explanation, “We’re both in.”

Their hands were so large on his waist that they almost spanned fully around him and suddenly the explicit images that plagued his brain came back in full force, he turned pink as he saw the two of them bending him over every available surface, plugging up both his holes, filling him up so good.

“You’re so cute hyung, I want to bend you over right here and show everyone else who you belong to.” Gunwook nosed at the shell of his ear, voice barely above a murmur.

Before Matthew could do something completely embarrassing like moaning, the younger was abruptly pulled away from him.

Hao stood over the three of them with a scowl, holding Gunwook by the scruff of his neck.

“Can the three of you keep it in your pants?!” He hissed, “Yujin is right there, and he doesn’t need to be traumatised again.”

They all nodded, now all supporting a familiar shade of pink across their cheeks.

.X.

The next time they were alone was the result of bribery and blackmail.

Gyuvin paid off Taerae to take Ricky and Yujin out for the evening while Matthew blackmailed Hanbin with the threat of telling Hao that he caught Hanbin fucking Jiwoong in their communal living space. The leader quickly agreed to take the rest of the hyung line out for as long as he could distract them.

They had the evening to themselves.

Matthew was pressed against the front door before he could even turn around. The side of his face was against the wooden surface and a broad chest pushed into his back.

“You’re all ours now hyungie,” Gyuvin growled into his ear as he ground his hips against his hyungs ass. Matthew could only bite back a moan. This was all he wanted. Gyuvin turned him around before he captured his lips hungrily, slipping his tongue into the elder’s mouth without hesitation. He was always a messy kisser, wet noises erupted in the relative quiet of the corridor. Matthew kissed back almost too turned on by just a kiss.

Another pair of arms came around both himself and Gyuvin, pulling them both into a tight hug, tugging at Matthew so he was in the middle of them.

“Let me have a go,” Gunwook pouted, far too adorable for his own good. “I didn’t get to taste you yet hyung.”

“Oh, I’m sorry puppy.” Matthew indulged his complaints and quickly threw his hands around the youngest’s neck, pulled him down and raised to his toes for a kiss.

His lips were soft, and he gasped in the kiss like he wasn’t ready, even though he asked for it. Gunwook cupped the older boy’s face gently like he was made of fine China and pressed kiss after kiss against his mouth. He bit at his plump lower lip before finally slipping his tongue inside.

Matthew felt like he was floating, where Gyuvin’s kisses were a frenzy; wet and needy, always stirring something deep in the pit of his stomach, Gunwook kissed like he was trying to heal him; his lips soft like he was scared to break him, calculated and precise in his attention, it made his chest ache with an entirely different kind of need.

He could feel Gyuvin behind him, his hands sliding up Matthew’s thighs to cup his ass.

“Up,” He said, lifting the smaller boy with no warning.

Matthew broke from the kiss with a yelp as he was deposited into Gunwook’s waiting arms, he was forced to wrap his legs around the younger boy’s waist.

“Wook ah, put him on my bed.” Gyuvin directed.

He felt himself heating up at the way they were treating him like he weighed nothing. He buried his head into Gunwook’s broad chest, ignoring the way the two taller boys cooed at his reaction.

They were in the bedroom in the blink of an eye and Matthew felt his heart pounding in his chest. It was finally happening. He was going to have both of them.

Gunwook placed him on the bed and climbed into the space between his legs. The youngest had a red tinge to his cheeks and his hair was slightly ruffled. Matthew let himself run his fingers through his soft locks.

Gyuvin climbed onto the bed beside them having shrugged off his hoodie and joggers already and his boxers did nothing to hide his growing erection.

“Hyung, I’ve been thinking about this for so long,” Gunwook spoke lightly, his hands seemed to be moving on autopilot as they tugged his hoodie up over his head and threw it to the side.

“I want to see how pretty you are when I’m deep inside you.” He continued.

Matthew let out an embarrassed whine, he could feel his dick twitching in interest, beads of precum dribbling from his tip.

The younger’s hands kept moving, removing Matthew’s top as well, leaving him bare-chested and blooming a pink blush.

Gunwook’s eyes hungrily took in the sight below him. His hyung was soft and small, with perfect alabaster skin and not a blemish in sight. His nipples were tiny pink buds that demanded to be played with.

And so, he did.

Thick fingers pinched and rolled the perky buds between them. He watched in amazement as his hyung fell apart so easily. He leaned down and captured one between his lips, sucking and teasing with his teeth.

“Ah! Wook-” Matthew squeaked, small hands tugging at his hair. He could feel how the elder’s heart was rabbiting in his chest.

He moved to the other side, locking eyes with Gyuvin who was shamelessly touching himself now, all his clothes gone and his large cock hard in his fist. He tilted his head to gesture the other boy towards him.

“Taste him...” He spoke around the nipple, moving on to broad strokes with his tongue.

Matthew watched as the eager boy leaned over and took his other peak into his mouth. He was shuddering now, thighs twitching at the overstimulation. The sight of both his lovers sucking on his nipples was burned into his retinas. His cock twitched and plumped up quickly. Gyuvin pulled back, and bit down on his chest without warning, pulling a short scream from his lips.

“Gyu!”

“Hyung, I’m gonna leave my mark on you, so everyone knows you’re mine.” He said, sucking a deep red mark beside his damp bud.

Gunwook pulled away all of a sudden, lips wet and eyes hazy.

Matthew couldn’t find any words; his brain was already clouded.

“I’ll leave my mark somewhere better.” The youngest murmured into his ear, pulling him into a fierce kiss.

“Ahh, don- don’t make it visible-” He managed to respond when they parted. His fingers struggled to find purchase on the younger.

“Don’t worry your pretty little head, I’ll mark you somewhere only we can see,” Gunwook smirked, a sudden surge of confidence filling him as his hyung was already reduced to a whimpering pile under him. Gunwook may not have had the most experience in the room but damn, was he a fast learner and he was going to figure out just how to break his hyung apart.

Matthew couldn’t find it in himself to object when he felt Gyuvin’s masterful hands pull away his underwear finally leaving him completely exposed.  The two taller boys kneeled between his legs, eyes raking over his smaller body. He shut his eyes, knowing how his cock was standing to attention, constantly dripping with precum, he could feel it pool on his flat tummy. He tried to draw his legs in to cover himself, but hands instantly gripped his thighs.

“Don’t even think about it, princess.” Gyuvin had a hungry look in his eyes. “How can you hide such a pretty thing from us? Don’t you think that’s unfair Gunwook ah?”

Gunwook nodded as he dipped his fingers in Matthew’s precum and brought it to his lips.

“You taste so good too,”

Matthew just panted in awe, trying to contain the shivers running through his body. The two boys looming over him looked like fallen gods, their bodies touched by angels; Gyuvin was slightly taller, with a wiry build but toned nonetheless, whereas Gunwook was broad and built; Matthew could trace the outline of his abs with his eyes.

“Let me try!” Gyuvin whined, but instead of dipping his own fingers, he leaned in to press his lips against Gunwook’s, licking a stripe against his lips before driving his tongue inside. The youngest seems dazed for a moment before responding hungrily. They kissed like it was a fight- a battle for dominance that neither was willing to give up.

Matthew wrapped a hand around his length as he watched the two go at it, the way they pulled at each other’s hair and their chests pressed against one another. It was like a wet dream come to life in front of him.

“Tasty,” Gyuvin muttered against Gunwook’s lips as they finally broke away from each other a string of saliva connecting them.

“I could just drink him- oh, hyung.” The puppy-like boy suddenly tutted, looking down at Matthew, “Who said you could touch yourself?” He grabbed his hyung’s hand away from his length and pressed it into the mattress beside him.

Matthew couldn’t help but whine petulantly.

“I- I want-” He stuttered, embarrassed under his dongsaeng’s gaze.

“What do you want, baby?” Gunwook spoke, his voice infuriatingly soft, taking Matthew’s sensitive length into his hand. It fit into his palm easily and disappeared from sight as he wrapped his fingers around it. He giggled. Matthew is not tiny, not in comparison to the average in fact, he knew he was just on the smaller side of average. It was just the hands he was in that made him seem so little.

 He went bright red, thighs twitching once again.

“I want-” He tried again after taking a shaky breath but lost it after Gunwook began to move, tugging his length experimentally.

“You want us to pay attention to you? Are we ignoring you Matthew ya,” Gyuvin fills in, amusement clear in his voice. Matthew wants to object to the way he drops his honorifics, but he can’t get his brain to string together a sentence.

“It’s okay, princess you still have our attention,” Gunwook cups his face and stamps a few quick kisses all over his face before trailing them down his body. Matthew realises what he’s about to do a moment before his lips press a kiss at the tip of his weeping, pink cock. That is followed by a wet lick- a stripe from the base of his length to the tip, lapping up the precum that was leaking from him directly from the source. Matthew shuddered and whined as the younger took the head into his mouth sucking softly at first, then pushing his tongue against the slit, earning him a hiss and an errant thrust into his mouth.

Gyuvin wasted no time in joining him; the two turned Matthew on his side pinning one leg down while the other was thrown over Gunwook’s shoulder. His tongue swirling around the length as he watched the older boy unravel at his touch. He soon had his entire length, taking it in entirely with each bob of his head. Matthew whimpered again and again, then he felt another pair of hands pull his cheeks apart. A shaky breath ghosted over his now exposed hole.

With no warning, a flattened tongue swiped against his puckered entrance.

“Ahh!” He tried to wiggle away, the sensation lighting up his body. It was no use the two giants held his body in position; Gunwook suckling on his length, tongue tracing the vein that ran under it and Gyuvin beginning to lap at his hole wildly, slobbering and penetrating his tight ring of muscle with his tongue.

His legs shook and he felt like he was being doused in flames the way his cock pulsed begging for release. He couldn’t even touch himself. He let out a whimper followed by tears streaming down his face.

Goosebumps rose on his skin as he knew he was getting close. Their tongues were taking him apart he shuddered, hips attempting to thrust wildly but were held in place by a bruising grip. His moans were getting louder as Gyuvin cupped his balls, massaging them while he licked. Gunwook clamped his mouth on the crease that joined his inner thigh to his butt and bit down making Matthew arch off the bed. He sucked until he was satisfied with his mark.

“Gyu! Wookie! Please, please. I need to cum!” He cried.

Gunwook’s hand came up to stroke his belly, he pulled away slightly from the sensitive cock. “Cum for us hyung, we got you.”

Matthew felt like he was hysterical, the way his body was trembling. Gunwook closed his mouth around him again and Gyuvin never relented his attack on his hole.

Only a few moments later he was finally tipped over the edge, cum shot out of him and down Gunwook’s willing throat. The younger swallowed down all of it with ease, using his hand to milk him dry.

Matthew felt like his eyes were glazed over, as he gasped for air, his body felt like jelly. Gyuvin finally pulled away, the bottom of his face glistened with spit and a pleased look across his face.

The two finally crawled back up to meet him at the top of the bed, lying on either side of him.

“You okay, baby boy?” Gyuvin asked caressing his face. Gunwook stroked at his thigh, causing spasms in his wake.

Matthew nodded. God. He was so much better than okay.

He never wanted to leave their arms again.

They both smiled down at him, Gyuvin’s hand slipping between his legs and prodding at his now sopping hole.

“You’re still good for our Gunwookie to fill you up?” He asked, his willing fingers pushing in- down to his knuckles in one quick motion eliciting a shocked squeal.

Matthew nodded again. He wanted to be filled. He wanted to be so full.

“With words please, hyungie,” Gunwook asked, nosing at the side of his neck.

Matthew turned to him, wide eyes boring into the younger boys, “Please fuck me Gunwook ah. Fuck me till I can’t walk and I’m so full of you.”

“Fuck.” Gunwook kissed him, “You’re too good to be true.”

He hesitated for only a moment before he spoke again, biting down a moan as he felt Gyuvin’s long fingers pumping in and out of him.

“I want both of you. At the same time.” He managed to gasp.

This got their attention again. Both pairs of eyes snap down to meet his.

“Hyung?” Gyuvin scanned his face, “Are you sure?”

Matthew tried not to back down, he wanted to be confident about this.

“I thought about it… a lot.” He confessed.

“What if we hurt you?” Gunwook asked, hand still rubbing soothing circles on his hyung’s stomach.

“I trust you, both of you- and really, you don’t have to do it- it was just an idea-”

“Wait, wait- we’ll do it,” Gyuvin and Gunwook seemed to be having a silent conversation, just with their eyes, Gyuvin pressed the pads of his fingers against the bundle of nerves deep inside Matthew, not even needing to pay attention to break him apart.

Gunwook nodded, “Yeah, I just- we need to make sure you’re prepped enough.”

Matthew felt his heart pounding in his ears as he nodded along.

Quickly and without much warning he was flipped onto all fours, legs parted and ass in the air presenting his hole for the both of them. He felt like the wind was knocked out of him as he tried to stay upright.

“Gunwook can start you off and I'll join after, okay baby?” Gyuvin dictated and passed a small tube of lube to their youngest, moving around to be sat by his head.

“Oo-ohkay,” He managed to reply unsteadily.

He could feel Gunwook shifting on the bed behind him, large hand stroking his lower back. Matthew held his breath as he felt the other boy parting his ass with one hand and guiding the bulbous head of his cock towards his entrance.

“Stop me if it hurts okay, hyungie,” He said before rubbing his tip around his entrance, suddenly Matthew felt something cold press against his hole and began to push inside. The first inch feels impossible and Matthew winces at the sheer girth of what is being pressed into him.

His legs tremble and his arms shake as the other boy continues to plunge himself deeper into Matthew. It's never-ending, and he finds himself gripping the sheets to stay upright.

“It’s okay, you’ve got this hyung,” Gyuvin comforts, running fingers through his hair.

All he can do is whimper as Gunwook is finally fully seated inside him. He’s so thick and heavy, Matthew’s cock is hard again, dripping precum onto the bed. It hurts so good. He’s around the same length as Gyuvin but much thicker, it feels like his tip is pressing on the base of his throat.

Gunwook grips his waist and begins to thrust. Each drag of his dick feels like a bulldozer and Matthew’s arms give way as he moans, pain and pleasure morphing into one. He falls on his face the only thing keeping him on his knees is the vicelike grip Gunwook has on him. His hips snapping at a savage pace, the sound of flesh against flesh echoes through the room.

His mouth lolled open, and he made grabby hands at Gyuvin. He wanted more. Luckily, the other boy knew him well enough to know what he needed at that moment. He shuffled forward and pushed his cock into Matthew’s mouth.

He let the elder suck on his cockhead before grabbing hold of his head and beginning to plunge inside, only taking seconds to hit the back of his throat.

“Mmhh—mm—” Matthew moaned around length, tears streaming down his face.

“Look at you hyung,” Gunwook spoke, “I thought you wanted fans to call you Woohyun oppa? Is this what an oppa looks like?” He thrust harshly, punctuating his words.

He couldn’t reply, he didn’t want to be an oppa. Not really.

“Maybe you should be calling us oppa, huh?” Gunwook continued, his hand pressing down on the spot between his hyung’s shoulder blades pushing him further into the mattress.

Matthew found himself nodding, and the cock slipped from his mouth.

“Oppa…” He whispered, “Wookie oppa…”

Gunwook’s grip on his waist got somehow tighter, no doubt he would bruise in the morning.

“Gyu oppa,” He moaned.

That feeling deep inside him was building again. Gyuvin laughed and patted his head before grabbing his face again and putting him back to work. He couldn’t move, the two giants held him in place as they fucked into him, and he could not be happier.

He was made for this. Just a toy for their pleasure. Theirs to look after and use.

Gunwook grunted as his thrusts became more and more haphazard, and he began hitting that precious bundle of nerves with every movement causing Matthew to writhe between them.

Gyuvin slowed his thrusts and cupped Matthew’s face.

“I want to cum down your throat, but I think Wookie isn’t going to last too long, should we try what you wanted, doll?”

“Okay,” He croaked, throat sore from exertion.

The two of them began to move around and Matthew tried to stay present, but his mind was all fuzzy and his limbs were jelly, so he let them move him around like a ragdoll.

He ended up on Gunwook’s lap, the boy was sitting against the headboard, he was straddling him, his cock buried deep inside him where it belonged. Gyuvin was kneeling behind them but close enough that he could feel his cock against the small of his back.

Gunwook stroked his hair and held his face between his hands, “Baby, I’m gonna lift you and Gyuvin is gonna try a finger first and we’ll see how it goes okay?”

“Okay, oppa.” The word fell from his lips easier than he ever thought it could.

Gunwook smiled softly at that, the blush never leaving his cheeks.

As promised, the younger lifted him slightly and Gyuvin’s long finger began to poke at the entrance, the finger was lubed and began to lightly breach him.

Matthew immediately sucked in a breath. It was already a lot. Gunwook’s cock stretched him more than Gyuvin’s had and to add another finger to that… it was a lot.

He felt a hand soothing his back, “Okay, deep breaths. I can stop.”

He shook his head.

No. It was not enough he needed more. He needed them both.

“I can take it. Just. Just give me a second.” His face was buried in the crook of Gunwook’s neck as he took shallow breaths trying to get used to the new intrusion.

He nodded a moment later and felt them begin to move, Gyuvin wiggled his finger in and out while Gunwook slowly bounced him on his lap.

That’s how it went for a little while; they added a finger and waited, slowly building one finger at a time.

At this rate, they were going to run out of lube.

“I think I’m ready,” He managed to mutter against Gunwook’s neck. They were all at breaking point, having practically edged the whole time they were stretching him, not wanting to cum early and waste the prep they did.

“You sure?” Gyuvin asked, four fingers still pressed into his hyung.

Matthew nodded. His brain had been on the edges of sanity since they began all of this and now all he could think of was cock. How much he wanted- no -needed to be filled up.

He held his breath as the younger pulled his fingers out and crowded into his space. He was well and truly sandwiched between them now; chest to chest with Gunwook and Gyuvin pressed against his back.

Gunwook pressed a soft kiss against his forehead and leaned over to do the same for Gyuvin too. Matthew felt his heart melt slightly at the sight.

“Okay princess, I’m gonna lift you again so Gyuvin can get in.” Gunwook wrapped his arm tightly around his slim waist, his other hand coming to Gyuvin’s waist.

Gyuvin peppered his neck with kisses and whispered in his ear, “Stop us the second it hurts too much, hyung I mean it.”

“I will. Promise.”

With that he finally felt Gyuvin move under him, his cock moving beside Gunwook’s, the tip nudging at his stretched rim.

The pain was like nothing he experienced before.

As he breached him lightning shot through his body and his hole throbbed in protest.

Fuck, they were going to tear him apart.

And he wasn’t going to stop them.

He knew he was making a noise, but he couldn’t register what it was.

“Hyung!” He thought that was Gyuvin. “I’m going to pull out!”

“No, no. Wait. Wait!” He cried out. “Let me get used to it, j-just just wait.”

His whole body was shaking as he took a deep breath and nodded for Gunwook to lower him slightly more.

He was burning from the inside out.

As Gyuvin got closer to being fully buried inside him, he felt black spots behind his eyelids, and he knew he was just fully sobbing now.

It felt like the two cocks were shoving his organs aside to make room for them.

He would never be the same again.

When they finally bottomed out Matthew was covered in sweat and collapsed against Gunwook’s broad chest.

Hands petted his head and stroked his thighs soothingly.

“It’s okay. Hyungie, you did so well.” Gunwook praised him and Matthew’s insides melted.

The pain was so much but he looked down towards his abdomen and suddenly it was worth it.

His usually flat tummy protruded out in front of him, the outline of not one; but two large cocks imprinted on his skin. They were so hot and heavy inside him.

“Fuck, that’s so hot.” Gyuvin’s voice came in his ear, the younger hooked his chin over his shoulder and wrapped a hand around him to feel his stomach. Gunwook did the same.

“You’re so hot hyung. Fuck.”

Matthew began to move his hips experimentally. He winced as the pain shot through him again.

“Just fuck me, I’ll get used to it.” He said gripping Gunwook’s shoulders.

His two lovers held his waist and slowly began to thrust up into his tight heat.

“Ah- Ah- Ah-” He gasped as the cocks moved in and out of him, dragging against his walls, and making obscene noises. The sound of skin against skin was becoming his favourite sound as he felt like he was going to pass out. It was all so much the pain finally began to mix with pleasure and he could see in their eyes too that this was not going to last long, they were all strung out and on edge. He began to grind his hips and threw his head back against Gyuvin’s shoulder, letting him press sloppy kisses against his neck.

“Ah! Oppa! Fuck me, fuck-” He whined and shook in their grasp. Gunwook’s thumbs moved against his nipples again and he leaned in to kiss Gyuvin too.

They were all gasping for air, their thrusts getting wilder and their fingers leaving bruises in their wake. Matthew was theirs. Theirs to hold, to fuck, to bruise…

Both cocks abused his prostate, pounding into him like jackhammers as he cried out. He was close.

“I’m- I’m gonna-” He stuttered, tears and spit marring his face.

“Cum for us, princess.” Gunwook slipped his tongue into his mouth, drinking him in like a starved man.

Not a moment later Matthew painted their chests white, shivering with overstimulation. The other two reached their climax right after, pressing in as deep as they could they flooded his insides with their seed.

The room fell quiet aside from their gasping breaths as Matthew leaned against Gunwook’s chest, no energy left to hold himself upright.

“Hyung, you’re so fucking perfect.”

“God. Look at you. Look how pretty you are.”

They showered him with affection as he tried to calm his hummingbird heart.

“Woah, look baby. Look how full you are.” Gyuvin said, awe evident in his voice.

All three of them stared down at his bulging belly, a small but very clear pouch was visible on his otherwise flat stomach.

Matthew stroked the belly, a sense of satisfaction flooding his senses.

“I got something for you.” Gyuvin reached over to the bedside table and pulled out a small bag, careful to avoid jostling his hyung who was very much still on his cock.

Inside the bag was a plug. Relatively big with a pink heart-shaped gem at the end.

Matthew thanked him with a kiss, words failing him in his worn-out state.

“How about we put it in and clean you up, hm?”

He nodded in response, brain still mushy and willing to do whatever his lovers wanted from him.

The process is simple Gunwook lifts him again, just enough for them to pull out without hurting him and Gyuvin can secure the plug, nestling it against his abused hole.

Matthew lets them lie him down and wipe away his tears with a damp cloth, getting any other bodily fluids in the process. He struggled to stay awake, stroking his full belly and letting the other two float in and out of his vision as they got ready for bed.

When they finally join him, he curled up into a ball with his two giants wrapped tightly around him on either side. Each of them held onto a part of him tightly.

“Gyu… Wookie…” He spoke with his last bit of energy.

“Hmm, hyungie?”

“What is it, princess?”

They both respond in his ear.

“I know we agreed to be non-exclusive, but I don’t want anyone else.” He mumbles.

There is a beat of silence before two pairs of lips attack him once more.

“Hyungie you already have us. You just say the word and we’re yours. Only yours.” Gunwook says in between kisses.

“Okay…” He giggles sleepily. “You’re mine.”

“Yours.” He hears two voices reply as he slips out of consciousness.

Heart and stomach full of their love.
