Work Text:
Your brothers often come to you for favors. Physical labour is one of the most frequent requests, along with handing out punishments in the form of octopus holds, but oftentimes they just want your company, which you'd never say no to. You think there's not a need for them to ask you for hugs because you'd still dish out loads of affection whether they ask for it or not. Having it returned is a bonus that makes you super happy. You like being pet and held like a teddy bear, especially after a busy day where you ended up running into walls, falling from trees and wrestling various beasts. It doesn't always happen, but the image of you coming back home covered in wounds is not uncommon either.
There is one person with the most demands out of everyone, however.
Osomatsu slides the door to the living room like a man who had just been drained of all life energy, the expression on his pale face pretty close to that of an undead corpse. As soon as he spots you, he drags his feet to where you're sitting and flops down heavily on your body, half successfully tackling you to the floor. There's no surprise in your reaction as your hand travels up and smoothly strokes his hair, while you look up to the ceiling.
"Niiiiiisan," you greet him, feeling the slight shift of his head against your chest.
You hear a long whine afterwards, slurred words that together should form your name, and then a stream of sniffles muffled by your jumpsuit. "Jyushimatsuuuu... life is so cruel to meeee..."
"Mhmmm. I see, I see." That's all you're going to say, letting actions speak further for you.
He must have lost his money at pachinko again. It's kind of easy to figure out what upsets your older brother when he tells you his troubles, and over three thirds of the time it's about losing money to something, be it gambling or getting scammed. You understand to a degree, but there is little help you can give unless he wants to borrow cash from you. At least, he's not doing that lately. Just getting comfort like this is enough to cheer him up.
Snuggled against you, he makes himself comfortable, dead weight inflicted on you like a big sack of rice. That's fine. You can handle an army of Osomatsus under you and still bench press them with your unnatural strength. The both of you stay like this in silence for few minutes. His hair is smooth under your touch, thanks to the shampoo and general care you lot give yourselves in the public baths.
You tear your gaze from the ceiling at last, looking down at the big brother who now seems so small in your arms. His ear is pressed against your chest, and though you can't see his face well from this angle, you're almost sure he has calmed down already. Listening to someone's heartbeat should have the effect of calming people's nerves, or at least that's s a rumor you heard once.
"Feeling better, niisan?"
"A tiny wittle bit," he replies, in a tone that suggests he's pouting. So you use your other hand to cup his cheek, finding wetness over it. Patiently, you swipe the spot with your thumb.
People cry for all reasons, even those you might consider petty, but if they cry it means it was important to them, so you learned to never judge those who are having emotional moments. It must also be why your brothers rely so much on you for comfort. You give Osomatsu a tender hug and rub his back, eliciting small sounds of appreciation from him. For being the unofficial leader of the bunch, your big brother can be so adorable.
"Why are you always so good to me?" you hear him murmur at some point.
What a silly question. No matter how many times your brothers ask you, it doesn't sound any less unnecessary. It should be obvious by now. But you weight your words anyway, and come up with something short. Anything more would sound repetitive at this point, and... it's the first thing that came into your mind, as if that holds the answer to everything.
"I love you, Osomatsu-niisan. That's why."
Silence. Osomatsu sniffles once again and finally lifts his head to face me. His eyes are glistening with tears and there's a bit of snot coming out of his nose, but otherwise he's showing his typical grin.
"Really?"
"Really really!"
"Really really really?"
"Really really really really!"
You go back and forth for a while, adding a 'really' to counter each other until you both are reduced to a laughing mess and decide to end the fake argument with your victory because he's chuckling too hard too continue. Once he recovers, Osomatsu supports himself on his elbows and climbs up to you, now face to face. You rest your hands on the small of his back, caressing him gently.
"Well, it wouldn't be fair if I said nothing to that." He rubs a finger under his nose in his usual gesture, eliminating the snot in the process and then wiping it over his shirt. It's not gross enough to you. "I love you too, Jyushimatsu."
You let out a cheerful "Yay!", using your no-indoor tone of voice at last. The fact it is a bit muffled by the collar of your jumpsuit over your mouth doesn't bother you.
"So... hmmm." He stares down at you, and then you see his lips form an exaggerate pucker before hearing a loud hum from him.
"Hmmm?" You imitate the gesture on reflex.
"Hmmmmmm."
"Hmmmmmm?"
He rolls his eyes, then snorts and holds back from laughing again. "Oh my god, just unzip that thing already!"
It takes you a moment to understand he means your collar, and quickly you free your hands to comply. Your wide smile is on full display as you pull the zip down to the collarbone and open your jumpsuit. "Like this?"
Osomatsu grins, wordlessly leaning in and shifting his arms so now they're encircling your head, getting access to your hair. You take the hint faster this time, and close both your eyes and mouth to welcome him. The touch of your lips sends a tingle in your stomach that grows into a small fire when he presses down further. His fingers in your hair give you unmatched bliss. He knows exactly which spots to massage in order to melt you in pleasure. Driven by enough stimulation, you respond to the kiss eagerly, giving access to his tongue and playing around with yours.
Making out with Osomatsu feels great everytime. He tastes like cigarettes and random food, sometimes alcohol, and sometimes a mix of the three plus something more. It's never unpleasant to you. Pulling him flush against yourself, you sigh in delight at his weight on your body, and grip at his shirt, not intending to let him go anytime soon.
He finishes the contact with a lash of his tongue against your lips, and grins as he peppers your chin and neck with smaller, tender kisses, probably amused by your squirming and whimpers as he knows you're ticklish. He buries his face just above your collarbone, inhaling and then letting out a sigh, brushing your skin with his hot breath. Your legs are now entangled, but you manage too rub his foot as some further gesture of affection. Once you start giving love to your brother, you can hardly stop.
"Are you gonna sleep?" you ask when everything becomes still, the only sign of life being his regular breath you can clearly feel over your bare neck.
You wait a while, but he doesn't answer. There will probably be some ache from staying in this position too long, and laying on the hard floor instead of the more comfortable couch, but it's alright. Having your big brother safe and happy next to you means a lot more than any form of physical pain.
"Have a good nap, Osomatsu-niisan."
