"One kiss a day, my darling," Karamatsu declares, the sunlight glinting off his shades, "I promise you this."
Jyushimatsu smiles like he doesn't really believe Karamatsu, but he nods all the same, sleeve over his mouth as he covers his smirk, "Okay, nii-san."
Little does he know how determined Karamatsu is.
Their relationship has bloomed into something beautiful; a flourishing, bright flower that only continues to grow, unhindered by the notion of society's morals. But alas, it has been quite difficult to nurture said flower, since they rarely have time alone. It was difficult when one has four other twins living under the same roof. Their daily activities differ greatly, too.
Karamatsu is determined to not let this flower of theirs perish. It must be fertilized with Love every so often, and Karamatsu will see to it.
"I promise, Jyushimatsu," he says again, tilting his shades down so his beloved can see how serious he is, "On our creator's grave."
Jyushimatsu's lovely this way, light dancing in his eyes. He definitely doesn't have that much faith in Karamatsu still. That is alright. Karamatsu will prove him wrong.
"Whatever you say, nii-san."

It is always tricky to talk to Jyushimatsu before bed, much less pull him aside after they’ve taken their turns brushing their teeth. Jyushimatsu is always keyed up this time of the night, comfortable and in slight rebellion against sleep, he’d be in a fight-ready state. But Karamatsu is ready, he catches Jyushimatsu’s wildly swinging hands right away after pulling Jyushimatsu away from the bathroom.
“Calm down, Jyushimatsu, it’s just your nii-san.”
Jyushimatsu’s smile widens and he settles down, instantly curious, “Ah okay, thought you wanted to fight! What’s up, Karamatsu nii-san?”
A quick glance around the hallway; Jyushimatsu's the last one to brush his teeth; and they are momentarily alone. Karamatsu leans in and kisses Jyushimatsu on the mouth, so much that Jyushimatsu’s back meets the wall and he is pinned. Jyushimatsu’s gasp of surprise is endearing, but he gets into the kiss immediately after, limbs going slack in Karamatsu’s hold.
Karamatsu takes his time. He has an eye open, just in case, because as tragic a romance as it will be if their family finds out, the aftermath won’t be desirable. And it’s always a pleasure seeing Jyushimatsu lost in touch, his expression almost serene. Something about this is thrilling. Stealing long, deep kisses from his forbidden sweetheart is exhilarating, and it is extremely difficult to pull away from Jyushimatsu.
But he manages, enamored by how Jyushimatsu blinks slowly after their parting, looking thoroughly dazed.
“A kiss a day, my little Jyushimatsu,” Karamatsu gently reminds him, brushing his thumb across the back of Jyushimatsu’s hand before letting it go, “I promised, remember?”
“Hah. You did!” Jyushimatsu breaks into a wide smile again, and loops his arms around Karamatsu, but makes no move for another kiss, “You really did it, nii-san!”
“Are you pleased?”
“Yeah! That was great!”
“Success.”
Jyushimatsu’s smile a little softer than usual, and it sends Karamatsu’s heart aflutter, “Uh huh. Bedtime smooch. I'll have good dreams tonight."
His greatest weakness, right here in his arms. His ruin.
One kiss a day was the promise, but Karamatsu figures that two or three would be fine, too.
♡
“Eh, nii-san. Pachinko’s over—oh!!”
Karamatsu would rather not express his love for Jyushimatsu somewhere filthy, as his love is pure and wholesome, but sometimes he just needs to take the opportunity presented in front of him. The alley is dark and empty, no one could see them unless they look hard, and Karamatsu has been thinking about kissing Jyushimatsu since the moment he got out of bed this morning.
So he might have gotten a little too excited, reaching up to thread his fingers into Jyushimatsu’s hair and kiss him fiercely. Jyushimatsu always responds well to aggression. It isn’t Karamatsu’s norm, but when he indulged, it’s wonderful; Jyushimatsu pushes into the kiss with a harsh groan and Karamatsu has to tug his hair a little, just to reel him in.
It is easy to get lost in this. Jyushimatsu’s hands lifts to grab at Karamatsu’s face, pulling him in even closer. There is no finesse, it’s kind of a mess, but Karamatsu’s more than turned on and Jyushimatsu’s gripping at him like Jyushimatsu wants to eat him.
The world falls away. Karamatsu can’t think about anything past this.
“Karamatsu nii-san,” Jyushimatsu growls out, almost, his voice rough and perfect, "I want more."
“Oh darling. Honey,” he pushes a thigh in between Jyushimatsu’s legs. His poor sweetheart, craving gratification and all Karamatsu wants to do is deliver, “I would hate to love you in a dirty alley. I want the best for you. I really—”
Jyushimatsu rolls his hips hard, practically humping Karamatsu’s leg and Karamatsu doesn’t want him to stop; Jyushimatsu looks wildly beautiful with pleasure. He’s so hard it hurts, and Jyushimatsu’s eyes are lidded and his mouth is parted and wet and Karamatsu just…
Karamatsu kisses him, and holds Jyushimatsu through his grinding, and tries not to be overwhelmed with love.

It’s all going wrong, today. He has had a perfect track record for their daily kisses; a full week; and he will not miss a kiss. Not even today.
Nothing has aligned in his favor; he usually finds a way to work around it and catch Jyushimatsu somewhere, but even his brother has had things to do the entire day. Karamatsu usually isn’t this antsy about not being able to kiss Jyushimatsu yet, but today feels like it'll be a missed opportunity. And he won’t allow that. His track record is perfect.
They’re on their way to the bathhouse and Karamatsu’s trying to act nonchalant, like he isn’t on edge. After their bath it’d be bed time, and he can’t keep counting on Jyushimatsu’s irregular trips to the bathroom to steal a kiss. He can’t—
“Oi, what are you so mad about?”
Karamatsu turns his head to see Osomatsu looking at him in confusion. He stops frowning; because he has been frowning it seems, really hard; and flashes Osomatsu a smile, “I was caught in my thoughts, brother. Frustration took hold of me.”
Osomatsu nods, his head still tilted in curiosity, “Huh, okay. Wanna talk about it?”
“Thank you for your kindness, but it's just one of my personal conflicts. It is truly a challenge, living as a guilty man, Osomatsu.”
"Internal drama again? Okay, okay. If you say so."
Jyushimatsu is behind them, having a conversation with Ichimatsu and Todomatsu, and the sound of his voice is making Karamatsu fidget. What can he do? Can he make an excuse and say he's forgotten something at home so he can go back and ask Jyushimatsu to accompany him and then kiss him fucking senseless or maybe he'd—
"You know, whatever it is, it probably isn't as bad as you think," Osomatsu continues, and Karamatsu's snapped out of his thoughts.
"Excuse me?"
"Not sure what you're thinking about, but you get too into something a lot, Karamatsu. Might want to take a few steps back and talk about it. In a normal way, if you actually want anyone to listen. That's why we're lucky, you know? We've got 5 different perspectives."
Osomatsu has a point. Karamatsu realizes that. "Ah...you're right. You're right," The turmoil in Karamatsu's chest dissipates, and he smiles sincerely at Osomatsu, "Thanks. I'll talk about it." It takes two to tango, after all. There are two people in a relationship.
His brother flashes him a thumbs up, and Karamatsu stops worrying.

They're in the bath, and Jyushimatsu has just resurfaced from dunking his head under the water. He pops up near Karamatsu, and grins at him, looking like the cutest, most mischievous imp in existence. Karamatsu's little imp.
"Jyushimatsu," he starts, an apology already bleeding into his tone, "It seems like my promise might just be broken. I didn't have a chance to kiss you today." Everyone else is occupied, it is just the two of them on this side of this bath, and Karamatsu isn't sure what kind of expression he had on his face right now, "I hate to admit that perhaps I've overestimated myself when I made the promise. Will you forgive me?"
The wide grin softens, and Jyushimatsu settles down in the bath to talk to him properly. “Karamatsu nii-san, it’s really fine,” Jyushimatsu’s hand touches his under the water, and Karamatsu exhales once their fingers lace together, “You’ve been really great. This week was really fun! But you don’t have to beat yourself up if it doesn’t happen.”
Jyushimatsu’s smile is so sweet. It’s one of Karamatsu’s favorite things about him, and there are so many things about his sunshine that he adores. He squeezes Jyushimatsu’s hand, “Wise words, Jyushimatsu.”
“Of course!” Jyushimatsu beams, and releases Karamatsu’s hand, standing up, “You’re so tense!!”
Wet, warm hands on his shoulders, and Jyushimatsu's kneading a little too hard, hard enough that Karamatsu yelps. Jyushimatsu loudly apologizes, holding Karamatsu in an odd chokehold, but presses his mouth to Karamatsu's ear in all the commotion, his voice a whisper, "Don't think about it too much. Kissing everyday or not is fine. I love you anyway."
Karamatsu grips at Jyushimatsu's arms, suddenly caught with emotions. There is no one in the world like Jyushimatsu, truly. Isn't it ironic, to have never been romanced, only to be thoroughly whirled away by his identical brother?
He blinks his tears away furiously, and it hopefully looks like he's just catching his breath from Jyushimatsu's wrestling move. He pats Jyushimatsu's arm, his heart thumping a mile a minute, "I love you too. So much."
Surely he isn't cool at all with the break in his voice. Jyushimatsu dips back into the water and swims around to look at him, his hands now cupping Karamatsu's face, "Nii-san, take a deep breath."
Karamatsu doesn't get to ask; he inhales sharply anyway, being with Jyushimatsu has taught him not to question things sometimes; and he is tugged into the water, his head fully immersed.
He feels something on his mouth then, opens his eyes to see Jyushimatsu kissing him, his darling's own eyes all slitted in amusement, and Karamatsu falls in love all over again.
They splash out of the water apart, and Karamatsu belatedly hears Choromatsu's voice asking them if they were okay.
Arm around Jyushimatsu, dripping wet, Karamatsu could only laugh with relief and joy. No matter what ridiculous pressure he put onto himself, he has his brothers to look to for help. Jyushimatsu will always be there to make it better. He's a guilty, guilty guy, but he's surrounded by his loved ones and his boyfriend and the flower he's nurtured is in full bloom. Everything is beautiful.
"We're great!"
