Tic...
Tac...
Tic... Tac...
The clock keeps on ticking as Gunwook has been standing in front of Matthew's door for the past five minutes. Checking the time on the clock every second, he can't help himself but to shift his weight from one leg to one other, or brush his hair back all nervously, impatiently waiting for the right time to come.
What Matthew isn't aware of, is that his newly roommate, but also colleague and best friend of three years, spent his entire evening baking him a blueberry cake. He knows it's his favorite, coming from a tradition he has with his family to eat one to celebrate a member's birthday. This year, his parents are in Canada so they cannot spend this special day together, but he didn't want him to give up on this annual habit.
Gunwook put all of his attention to make sure that his hyung would not leave his room, begging Taerae earlier to keep him busy with any video game they could play or whatever could keep him out of the kitchen for hours.
So here is now a very tense Gunwook, holding a plate filled with two slices of the cake he carefully prepared in one hand, while the other is covering the bright flames of the '2' and '4' candles he bought this morning and tried to hide all day to keep the surprise.
11:57PM
It's time for Taerae to leave the place for Gunwook. "I have to go to the restroom, let's put pause to the game, i'll be right back." He hears him blabber as an excuse to go out for a second. "Hmm, no worries!" Matthew responds nonchalantly, not expecting what, -or who- is waiting for him.
Gunwook steps back a little to not be shown while his parter in crime opens the door. Tae sends him a lil wink in encouragement when they meet , patting his back slightly before leaving the apartment to leave them all alone, informed about the plans of the former one, the latter has a very good night ahead planned at his boyfriend's dorm, Jiwoong.
The tall man suddenly feels his palms starting to get sweaty, as the tension arise in his stomach from being now left all alone.
More than not knowing about his birthday surprise, if there's one thing that Matthew might not be aware of is the feelings of his younger member for him. Even if he hasn't been quite subtle about it...
At least, that's what Gunwook thinks.
From hugging daily to sleeping together bodies tangled up as if it was something very normal between friends, Gunwook has found himself slowly falling in love the very bright and caring man that Matthew is. Each moment spent together always felt like being absorbed in a timeline where there's only the two of them, where nothing else matter an where they can freely be themselves and enjoy each other's presence.
They actually kissed once.
By pure accident.
Both were playing with Gia which wasn't in the mood for any physical touch, leaving the two men's mouths meet instead of kissing the cat's fur at the same time.
It was brief, but the slight brush of their lips was the best feeling Gunwook has ever felt. To the point it has been stuck in his head for months, now.
He would always replay that moment alone in his bed, at night, imagining what would have happened if he had been braver at that time instead of running away.
Gunwook shakes his head, trying to focus again as he needs to lock in, removing any distraction from his mind. No need for a boner now. Especially now.
May 28th 2026, 00:00
"Happy birthday to you! Happy birthday to you, Mashu hyung! Happy birthday to you!" sings happily Gunwook as he enters the room slowly, leaving Matthew in a complete but happy surprise.
"Gunwook-a! Thank you" expresses the older in a big smile, grateful for this attention. "Is that a blueberry cake?" he asks as he stands up to close the distance between the two. "You remembered how much I love them!"
Captivated by the older's shining eyes and very kissable lips as he gathers them in an adorable pout, the younger feels his cheeks starting to feel warmer under his skin. "Of.. of course, I did sweetheart", he replies, trying not to stutter on his words.
Under the sweet name, Matthew is melting a bit more under the youngest's charms. Instinctively, he reaches an hand to Gunwook's cheek, brushing it softly with his thumb, deeply touched by his attention. He picks up the plate from him and puts it on the desk on their left, aiming for a very tight hug, which surprises the maknae at first, trying to contain himself another time as their hot and firm bodies are getting closer.
Both only wearing a tank top and sweatpants, their muscles meet in a warm embrace.
There's nothing to do.
Gunwook's heart is about to burst in its cage as he feels Matthew's head finds its spot in the hollow of his bare neck, resting there for a moment as his arms are trying to wrap around his waist, which is barely possible in comparison of their body sizes, while Gunwook does it so easily. It's as if Matthew disappeared in his embrace for an instant. The thought makes the youngest's crotch twitch in his pants, which is not the right time. Again. This makes him break the hug, in fear of being noticed, now all flustered.
"Should we eat, hyung?"
Which they do.
Both sitting on the bed, legs crossed in front of them, they devour the cake with their forks.
"Gunwook, please! This is so good, seriously!" exclaims the older, his mouth still full, which makes the youngest smile so wide.
He wonders for a second about how this sentence would sound in another context, his own mouth filled with something else. Maybe something even more delicious than the cake he prepared, he's certain.
Gunwook actually lets his inner thoughts win for once when he notices a bit of cream at the corner of Matt's lips, capturing them on the tip of his fingers, that he brings to his mouth in order to lick the dirt.
Something about the movement makes Matthew visibly glitch, forgetting how to breathe for a second. He swallows with difficulty, not being able to stay in place and trying to change his position on the bed. He puts an hand to his forehead as if he got a fever.
Of course, Gunwook is oblivious again at the reaction the older has always shown him in return to his actions.
"Did Taerae disappear?" Asks Matthew, trying to contain himself.
"He did." answers quickly the tall man, his gaze fixed on the food, too anxious to look in the other's eyes. "He got a call from Jiwoong hyung."
He regrets lying but would not have been able to tell him "Hey, so I planned days ahead that Taerae hyung would leave home and have a sweet date with his Jiwoong as i'm here with you for your birthday maybe trying to confess to you or at least just spend this moment together, just the both of you". No, he would never.
"Oh, Jiwoon hyung! He just could've have come home, we would have celebrated together. That sucks." sulks Matt, which Gunwook cannot resist, he doesn't want him to be sad about anything in his life.
"I actually wanted it to be just the two of us, in reality."
Or maybe Gunwook has some courage left in his body after all.
"Then, I'm okay with that." smiles the hyung all brightly, cheeks visibly red.
The two of them continues to eat while discussing of this and that. Suddenly, Gunwook remembers something really important as he takes a closer look at their plate. His eyes never opened this wide before. Starting to brush his hair back crazily, he's starting to get all sweaty again.
"Hyung! You didn't blow out your candles!" he screams as his initial plan didn't work out. "They might have gone out while we were..."
"Hugging." cuts Matthew. "They did. But we can light them up again, right?".
There's something about Matt's expression that Gunwook doesn't seem to capture, like something shifted between them, but he cannot seem to put a finger on what yet.
Lightening up the candles again, Matthew gets ready to blow them quickly, fork still in hand, craving for another bite of cake, but he still wants to make the youngest happy.
"Wait! You have to make a wish, hyung!" exclaims Gunwook before it's too late.
Then, the person he loves the most in this world closes his eyes tightly, hands joined in front of himself, taking his time to make a wish correctly.
Gunwook can't help himself but stare at each detail about Matthew. Each feature that only belongs to him. From his round nose to his pink cheeks, to the small strands of hair falling up on his long lashes, to down to his plumped lips that seems to beg for a kiss.
Time feels like suspended but restarts once Matthew's eyes open again.
This time, Gunwook understands what has changed.
Caught looking at his secret-lover, he is gratified with the same gaze full of admiration.
No.
The same gaze full of love.
He knows it perfectly, because this is exactly how he looks at his hyung.
Matthew opens his mouth slightly, finally blowing the candles, never breaking the eye contact with Gunwook.
01:27A.M
After eating and talking for around an hour and half, Gunwook feels like time has come to sleep as he doesn't want to put any pressure on Matthew to spend time with him, even if he knows this never has been an issue before. But he feels like he did enough for tonight, even if he wasn't able to confess as he secretly wanted at first.
"Would you stay over for the night?" Matthew asks with courage when Gunwook's hands lies on the doorknob.
Making a U-turn, Gunwook offers a really confused face, as if they didn't sleep together some nights ago on the same day they filmed for their set-log that got posted on Instagram. Which they actually completely forgot about as they were too busy enjoying being on each other's arms.
"I mean, you still haven't received your bed..." tries the oldest, as if to convince himself more than the youngest. "And... I do have a bed. This would be more convenient for you, it's late and we have Mcountdown in some hours."
Gunwook didn't even need that many arguments as he would actually always accept to sleep with Matthew.
But for once, he does hesitate.
Scared of his own feelings? Scared of the eventual mutuals feelings? Or scared about how his body would react when he spent the night lurking for the other's lips?
"Please, stay with me." begs Matthew from his bed, curled up on himself, which isn't usual coming from the man with much confidence.
Forgetting about thinking about it twice, Gunwook turns off the lights as an answer, leaving only the moon's shine on the room.
One thing about Matt and Gunwook is that even when they sleep with each other, or with any of the members actually, they cannot bear to keep their pants on, they are so used to sleep in their underwear. Which is not that convenient knowing the dirty thoughts coming to the youngest's mind.
Removing his jogging, even with the darkness of the room, Gunwook gulps with difficulties at the sight of his hyung in briefs. He almost chocks on his own saliva when he notices a very visible wet mark that was left there, as well as a provident bulge that is not so shy.
"Oh this night's gonna be a torture" he thinks silently to himself, replacing his own cock correctly while he undresses as well.
Cuddled up together, Matt's back lies on Gunwook's chest while his arms are wrapped around him, their respective tank tops being the only thing separating their skins.
The youngest actually needs to do some inner meditation to not get hard as he feels the oldest this close to him. More than that, just knowing that the man he is sleeping with was hard minutes ago and might still be, is driving him insanely crazy.
They rarely sleep this tightly, but Gunwook couldn't say no to his hyung's idea... which is now making him fight with himself as he feels the warm of the other's body pulse in his own lower part.
After long minutes, Matthew's breath seems to slow down to the point it makes Gunwook think he's fast asleep in his arms.
But suddenly, a question pops out of nowhere.
"Did you..." he hesitates for a bit. "Did you write Customize about.. about us?" asks the hyung to his maknae.
Oh.
Gunwook considers for a second if he should pretend to be asleep or finally take this opportunity to be brave and say the right things.
"Nevermind. You might be sleeping already." murmurs Matt.
He takes a deep breathe.
"But i was really curious. I think I would love it to, to be honest." his words wander in the emptiness of the room, but resonate deep in Gunwook's heart, as he always dreamed of this moment. "I want it to be about us".
"It is." finally replies Gunwook with all the courage he could bring up to himself for this exact moment.
Matt startles with surprise, being certain that nobody would hear his confession.
Gunwook makes him slowly turn around so that they can now face each other.
They exchange their breathes, being closer than they ever did before, resting on their foreheads.
They are to the point where they don't know if it's the weather of May that is making them sweat this much or if this is due to the frenetic heartbeats in their ribcage that menace to burst out.
"It's true, even if we're not meant to be...," starts Gunwook while brushing Matthew's hair softly. "I'll choose you anyway".
Gunwook doesn't have any time to understand what is happening.
Suddenly,
Matthew's lips meet his.
It's the sweetest kiss he ever had of his life.
It's even better than in his dreams. Even better than what he used to imagine every night before putting himself to sleep. Even better than everything he could have ever dreamed of.
Matthew steps back for a second with a wide smile that rises up to his eyes, his cheeks all flushed.
Gunwook doesn't hesitate a second from now on and reaches for Matthew's nape with his big hand and closes back the distance by deepening the kiss the oldest initiated seconds ago, hungry of his mouth.
"Hmm" moans Matthew between their lips, enjoying the touch of Gunwook's tongue finding its way to his as he grips thightly on his hair, pulling on them slightly to adjust the angle.
"That's true, you know all of me" whispers the producer in between kisses. "Make me all yours. Make me feel customized."
"Would you allow us to cross the line?" Matthew asks hesitantly.
"Isn't it what we are doing right now?" he says, finally regaining all the confidence he lost. "I want you as much as you want me, if not more. Customize me, make me yours as you want me to be"
Matthew takes the lead and switch their positions, now sitting on Gunwook's lap.
Their lips finally separate, leaving an heavy saliva trail behind, wetting both of their chins. The older starts his way down on the youngest's body, biting his neck to claim it all his, and then licking with his tongue to calm down the sensation.
"I dreamed of this for so long." confesses Gunwook as he moans out Matthew's name.
"Oh I know, sweetheart. I know that too well." replies the hyung as his fingers find their way down to the edge of his maknae's tank top, removing it quickly after getting a nod as an okay to continue.
"Why did it take us this long?"
"Maybe we were both just as scared." understands Matt, playing with the nipples of his lover.
"Hmm.." moans the latter. "Now, let's be fully confident, promise?"
"I promise."
As Matthew's mouth finds its way to Gunwook's tits, he starts moving his hips in a slow movement that drives the youngest crazy, who moves in return to meet him.
They both feel their cock getting harder than ever by every slight touch.
"I don't understand why people call you a fox" randomly says Gunwook, putting his hand to his mouth to contain his screams.
"What are you even talking about right now?"
"I mean, look at you nipping on me. You're definitely a... Hmm.." he makes a pause, enjoying how his tongue traces the outline of his abs "a.. a.."
"What am I then? Yours?" he says jokingly while doing the most obsene things.
"My little kitty".
Matthew swears his cock never twitched this much at hearing such simple words.
"I like that." replies the hyung while bringing the other's boxers down with his teeth, letting his huge cock arise up to his stomach, squirming all brightly with heavy pre-cum.
Matthew licks his lips in admiration.
He. Does. Love. The. View.
"Would you allow me to take over?" asks Gunwook. "It's your birthday after all, let me treat you well."
"Please do". Pleads Matt. "I want you. Fully in me" he completes, leaving no place for doubt, which makes Wook whine in satisfaction.
Aggriping his waist with his big hands, he takes the lead and now is all over Matthew's small but very well built body.
In comparison to his full naked body, Matthew still is wearing his clothes which is only a question of time before Gunwook removes his tank top off. But he actually want to tease him a bit, playing with the edge of his briefs.
"You cannot imagine how much effect those have on me" confesses Gunwook as he puts his head down to kiss the inside of the sensitive sweet skin of his thights, leaving Matthew breathless.
"Oh i do. Look at you being so hard and wet for me already."
"That's right. But what about you?" questions Gunwook as he finally pulls down the other's briefs, freeing him from the tension that was stuck and gathered in his underwear.
"Oh." stops Gunwook. "I'm gonna have a feast, i fear."
His hand reaches for Matt's tip that has been leaking for long minutes, which makes him twitch in his palm. With his thumb, he gently plays with it to rise up the tension.
He then gathers the pre-cum on his fingers and copies his action from earlier with the cake, putting them directly to his mouth, taking a taste of his man.
The view is making Matthew's eyes heavy in desire, losing patience in need to be touched, sighing in need.
"You taste so good, but be patient little kitty. I have been waiting for this moment for too long to end it already."
"Gunwook-a.. I want..."
"Use your words, you can do that for me, right?"
"I want you to... to touch me. Please."
"See, it's not that difficult." he replies, slowly palming him in return, which makes Matthew moan in relief.
It's only a matter of seconds before Gunwook goes down to explore the oldest's body. Mouth meeting with his tip, while one of his hand strokes the base of his crotch and the other plays with his nipple.
Playfully, teasingly, he licks him from the base to the tip, enjoying the delicious lenght of his hyung, tattoing every single vein on his tongue.
He finally deepens the movement, taking him fully in after some pleading.
Matthew starts to see stars and keeps on whimpering, tears collected at the corners of his eyes.
"Gunwook... God..This feels so good."
"You're delicious, my love"
"Please, would you go in, now?" Matthews asks all impatient. "To be fully honest, I prepared myself a bit earlier today." he confesses, face getting all red to say it out loud.
"You... when we still weren't a thing?" he stutters, raising his head to meet his hyung's eyes.
"We always were a thing, Wook. Maybe I prepared myself quite frequently for the day it would come..."
"And how often would you do that? Thinking of me?"
"Almost.. daily. And yeah. Always thinking of you. Only you."
No more words were needed for Gunwook to climb up on Matthew, reaching again for a kiss that he intensifies immediately, running his tongue all over in his mouth, moving his hips in sort of making both of their cock meet and brush against each other, making them even harder as their bodies makes a beautiful melody.
"Do you have lube?"
"Se.. second drawer, on your right"
Opening the cap, he applies a generous amount on his fingers, that he preps carefully before playing around Matthew's rim. Once he hears enough moans coming from him, he puts not one but two fingers in directly, knowing he is too impatient to wait anymore.
He drags his way inside, meeting the tight closeness that he has been dreaming of.
Matthew reaches for Gunwook's cock and the latter copies his movement and then they start masturbing each other with eager, while his fingers are still inside, trying to find that sensitive spot.
Their moans get louder as they know that nobody will come to disturb them, allowing the moment to be very noisy.
"Gunwook... I will not be able to... wait longer.. I need you now."
Helping him to find his entrance, he directs Gunwook right into it, his tip finally meeting the rim.
Matthew puts his legs around Gunwook's waist to guide him to go deeper, which he does.
The sensation is burning as it streches Matthew's inside, but this is such a delicious pleasure. People always jokingly said that Gunwook was huge, but there was no lie.
Gunwook feels him tightens around his cock as he starts moving slowly to test out his resistance.
Matthew grabs the other's hair, begging for a kiss, which he does in an instant.
Lips against lips. Palm against one's cock. The other's inside one's intimacy. And all makes the perfect scenario they both wanted for a long time.
"Dee.. Deeper please." Matthews ask "Hmm Gunwook, I'll never get tired of this."
Tears are now running down his cheeks by how big Gunwook is inside him, and he cannot help himself but let out a loud moan as his lover grabs his legs to put them on his shoulders, making their movements more intense as he youngest keeps on going in and out.
The sounds of their wet skin envelops the room just as their whines do too.
Both are about to reach their peak when Gunwook hardens his movements.
"Can.. Can I come inside you?" he asks now a bit timidly.
"Hmm.." nods Matthew, not able to let a word out anymore except..
"Gunwook... Oh.. Gunwook." he moans, grasping on his nape, in between kisses.
"I'm so close, hyung"
"Me too"
Both about to reach their end, their movements get less precise, very messy, but it is such a beautiful mess if it's the two of them.
"I love you, Gunwook." Matthew finally confesses what he has been holding in his heart for too long as he come on their torso, leaving white marks everywhere between them.
"I love you too, Matthew." Gunwook replies, more confident than ever, also coming, inside the walls of his now lover.
They stay like this for a moment, all lovingly and smiley, sliding to the side so that they can hug while Gunwook remains inside Matthew, which makes them hard again the second Matthew makes a slight move.
After a second round, they take a look at the clock, they only have one hour of sleep left before having to leave for today's Mcountdown. But they do not regret anything about this night, were they finally crossed the line.
"Do you think that we will win the trophy, today?" Matthew asks timidly
"I'm pretty sure. I trust our zerose. But one thing for sure, is that as long as you're by my side, I'll feel like winning everyday."
Matthew leaves a kiss on his forehead, grateful for his words.
"Wait. I also had a question" adds Gunwook.
"Hm?"
"Would you tell me what was your wish earlier? When you blew the candles?"
Matthew smiles.
"I wished for this exact moment to happen".
Gunwook couldn't be happier at this exact moment.
"Happy birthday, my first."
