hear me out, how do the guys react with their s/o growing up? I means, monsters age very slowly don’t they? And plus, skeletons don’t seem the type to even age at all. But a human? As the years pass our features change. How do they react to that? Not in an old age way, just, the passing of time.
(love your writing so so much!!)
Personally, I'm in the camp that monsters (besides boss monsters ofc) all age differently according to species. I've never vibed all that much with the skelebros being like 500+ years old/immortal in fics, but I definitely do headcanon that they age slower compared to humans.
This def could've gotten super angsty, but I went the cute fluffy route with it :)
Sans is smitten by watching your laugh lines grow and deepen throughout the years. It's evidence of himself and the impact he's had on your life.
Papyrus is excited to indulge your new explorations into food and cooking. He loves picking up a new recipe with you every week and tuning it to your liking and nutritional needs. Experimenting with recipes is something he's never been afraid of, and with a controlled helping hand in the kitchen, maybe he can even make something original AND edible.
Blue LOVES that he gets to show off his strength more for you when you lose the flexibility to do certain things. Please let him carry you up the stairs, it will get him a high no drug could ever achieve.
Stretch comes to love the way you dress as you get older. Old t-shirts, sweatpants, mismatched socks -- nothing elaborate, the perfect fit for comfy days, every day.
Red finds it cute how you sometimes find yourself acting more like his parent than his partner. Having him dress warmer than just shorts, chiding him about his smoking, and being overall worried about what he eats; he likes being fussed over, especially when you're pushy about it.
Edge takes pride in the ways he supports you, even if he gets a bit crass about it. No, you're wearing a jacket out, you're gonna catch a cold. Come on, you need to do your stretches so you're not completely frail another decade down the line. What you put in your body is important, let him handle the cooking (fine, you can help, but only with measuring the ingredients!). He likes fussing over you, even if he gets pushy in showing that he cares.
Black loves your confidence and how you don't shy away from conflict and arguments anymore. You're not a hothead by any means, but it does get him going when you aren't afraid to confront problems with you "I'm too old for this shit" attitude.
Mutt finds it endearing how you need glasses for your farsightedness now. He carries around your reading glasses for you and always offers them up when you realize you have to read something and curse yourself for forgetting them.
Mal loves spurring you on to be feisty. He thinks having a short fuse at an age where you could easily be bested by someone younger and more agile than yourself (keeping in mind how his Underground functioned) is the hottest show of confidence someone could ever sport.
Cash makes frequent comments that you'd make a great milf/dilf/pilf. Is this his way of saying he wants to settle down and have kids? Who knows! He's never gonna be straight to the point with you, even after being together for this long.
Axe loves your new inclination to naps and early bedtimes. He's ready to crash with you at 8pm on the dot, so get over here and get cozy with him.
Birch loves picking up new homebody hobbies with you, like knitting, quilting, and putting together puzzles and models. He also loves watching you grow and master the hobbies you've been doing since you were young.
Killer loooves to use you as an excuse to get out of things. Oh, yeah, he can't do that, he has to get home to take care of his poor, elderly, geriatric partner (you're 43).
Dust favors the comfortable quiet and the parallel play you so easily fall into now. He's always been quiet, and you've always accepted that, of course, but now that you're secure in your relationship with each other, the silence is in palpable solace.
Nightmare likes watching you mentally mature. Sure, you were fun when you were young and stupid and adorably arrogant, but now you're wise and witty with him, and that's just so much better. You're also much more fun to complain about the youth with.
Dream just likes watching you change in general. He will never age, so watching time morph the body and mind of someone he loves is fascinating. He celebrates every milestone, no matter how small.
Ink enjoys documenting the changes of your body. His own body is static, and it will be until the day he's forgotten and crumbles to dust, but you get to be in constant metamorphosis your whole life. He's got thousands of studies on how your muscles and fat deposits and skin have all changed over the years, and he treasures them all.
Error finds comfort in how your body changes, but your soul doesn't. You still crinkle your nose like that when you laugh, and you still quote those old movies and shows when the context is right. It's nice to have something stable, something familiar, like that in his life, even through the passage of time.
Fresh loves how your humor slowly becomes more corny and outdated. Bro was born on the cob, corniness runs in his marrow. Make a goofy reference about something from 30 years ago, he'll love it.
Cross likes the stability and routine that comes with age. You come home to each other, make dinner together, and share quiet evenings in each other's company. He's yearned for a quiet life like this for a long time.
Epic enjoys how much the relatability between the two of you increases. You got a kink in your neck? Yeah, he woke up with a slipped disc, welcome to the club.
Delta loves watching you try to party like you used to in your 20s. Somehow, you make nearly throwing out your back dancing look sexy. You also look so adorable waking up with a violent migraine from just one margarita. Here, let him take care of you for the day.
Color thinks it's selfish, but he can't deny that he likes how you've lost your seemingly endless youthful energy and now have a preference for staying in during the weekend. He's always preferred date nights at home, bundled up with an episode or two of a drama thriller and a shared bowl of popcorn.
Ccino likes watching you learn to appreciate the small things in life -- the smell of a new blend, short poems written on napkins between customers, the comfort of silence with someone you love. He hopes he can share many, many more of these little moments with you.
Reaper loves watching all your fears and insecurities fall away with age. What once made your palms sweaty and your heart pound now makes you laugh and reminisce on when you were younger. You've really grown into yourself and become someone so wonderful.
Plum adores calling you his cougar/silver fox. It's not just a joke, though -- he genuinely gets more attracted to you the more mature you become.
G loves the way your hair starts to gray and he has you make a wish on them every time he finds a new gray hair. He's a sucker for a little salt and pepper.
Saejun loves watching your skin change with age. All your new freckles and moles and mottles make up a brand new constellation across your body for him to map.
