Can you please do Papyrus and Sans (and their underfell and under swap versions) reacting to an so who likes to bite as a sign of affection?
I love the thought of them just trying to go about their day and then chomp
UT, UF, and US skeles with an S/O who bites to show affection
Undertale:
Sans:
PLEASE warn him before you do this the first time because he will 100% freeze up if he isn't prepared for it
After he knows why you're doing it though, Sans can't stop himself from laughing at it
He appreciates it that you get so overwhelmed by your affection for him that you can't show it in any way but biting him, but he's going to teasingly offer other, less startling ways to express it
Kisses? He can do those. Picking him up and spinning him around? He can handle that. Biting him? Now he might playfully scold you for catching you off guard
Once he's used to it a little more, he learns to pick up the signs of an incoming bite - and he'll absolutely try to make jokes and puns to throw you off
Papyrus:
After his initial shock passes, it very quickly becomes a competition to see who can out-do each other with over the top affection
Papyrus grabs your face and rubs his all over it in the best approximation of a kiss he can manage, all while laughing the entire time
He might offhandedly compare you to the royal guard dogs who have tried to take off with his bone attacks, but anyone can see the playfulness in his eyesockets
It startles him every single time that you bite him out of the blue, but every single time it ends in him gushing about how much he loves you too
Underfell:
Red:
Oh boy have you opened up a whole can of worms by doing this
Red will very quickly see it as a challenge to see who can bite harder, and believe me when I say that he will win that little battle
It gives him a good laugh every single time you chomp down on him out of the blue, and no matter when or where it is, he makes sure to return the favor with equal eagerness
His teeth are sharper than most, which usually ends in some minor accidents, but he will always always make sure to clean up any blood and make it up to you in some way or another
The go to is usually a trip to Grillby's with the promise that you'll be allowed to get everything you could possible want
However, neither of you are surprised in the slightest when he takes a good few bites of everything you get, saying that he has to make sure it's up to his standards
Edge:
The first time you do this to him, it startles him so badly that he lets out the most undignified shriek he's ever made in his life
He'll scold you while his cheekbones are practically glowing red with that flush of magic you adore
While he doesn't scream after that first time, it flusters him so so much every time you bite him
Despite how much he claims to hate it, you never see him actually try to stop you, but you do see the way he lowers himself down to your level to make it easier for you to reach whenever he picks up on the signs that you're about to bite
It isn't uncommon for him to very quickly speed off to clean or train after - his usual way to calm down after something manages to fluster him
Underswap:
Blue:
He immediately freezes up every time it happens, only to break out in a fit of muffled laughter
"IS THIS WHAT PEOPLE MEAN WHEN THEY TALK ABOUT CUTENESS AGGRESSION? I KNOW YOU LIKE ME, BUT I DIDN'T KNOW YOU THOUGHT I WAS THAT CUTE!"
No matter how many times you do it, he somehow always knows exactly when you're planing to sneak up on him to chomp and to show him how much you love him
Blue might tease you a little bit by saying that he's not a chewtoy, and might even offer to buy you those little rubber necklaces for you chew on if you really feel need to
Stretch:
He's another one of the skeletons who audibly yelps every time you chomp down on him, but he finds it endearing
You feel so much affection for him that you can't think of any other way to show it but to bite him? Oh, he thinks it's the most adorable thing in the world
If he has the chance, he likes to flop himself on top of you like a very bony weighted blanket, saying that you're in time out
He might carefully bite back to get revenge, but it's never enough to really do anything but tickle an make you laugh
☆ Their S/O snorts for the first time around them.
☆Warning(s) None
☆Author Note(s) I snort a lot when I laugh and I think its adorable when others do it. I'm heavily in my Undertale hyperfixation faze, so expect me to write a lot about it for a while. Great time to request some undertale stuff ;)
..★.──────────────────╯
UT! Sans ☆
Rises his eyebrows(?) and smirks a bit wider. With a light blue dusted on his cheek bones, Sans start shooting off as many puns as possible just to make you laugh harder. By the end you can hardly breathe and your face is flush, making it feel warm. Which you really only notice when you go up to your face to message out the soreness from smiling to much.
Thinks its adorable. Probably makes a couple puns about it but would never make fun of you.
UF! Sans ☆
"Damn sweetheart, didn't mean to tickle your funny bone."
His smirk grows into a shit eating grin, showing his sharp teeth a bit more. He goes on for another 10 minutes, wanting to hear what other noises he could possibly get from you. Its only until he's worried that you might pass out from lack of oxygen that he starts to lay off.
He one hundred percent snorts too, doesn't mind it at all. Doesn't mean he won't tease you a little bit though, its just in his nature.
US! Papyrus ☆
Pauses for a second before laughing with you, hard. Don't take it as an insult, Papyrus just thinks its cute. Makes sure to tell you this with a wink too. For the rest of the time spent, he stares with you with a orange glow on his face and a gentle look in his eyes. Makes it a challenge for himself to make you snort as much as possible for the foreseeable future. (Be prepared for a lot of bad puns.)
Papyrus admires you for it, seeing you happy in the first place honestly makes his soul jump a bit. Tries to make you snort in front of others just to fluster you, but doesn't ever make you feel bad about it. Immediately reassures you if you think its weird or embarrassing.

You just wanted a cool, oversized leather jacket to wear incognito.
Unfortunately, your navigation skills failed you, and you ended up in the wrong aisle of a very confusing department store.
“hey, pal. you look lost,” a lazy voice rasped. You turned to see a skeleton in a blue hoodie, holding a can of tomato soup. “I am,” you admitted, pulling down your sunglasses “Do you know where the clothes section is? I’ve been looking for jackets for twenty minutes”
Sans blinked, staring at the literal towers of Campbell’s surrounding you both. “kid…you’re in the soup aisle.”
“Well, yeah, but I thought it was a multi-level–”
“Why are you buying clothes at the soup store?” Sans interrupted, a grin slowly spreading across his face.
You choked on a laugh, realizing how ridiculous you looked in your high-fashion disguise amidst canned broth. “Fair point, I’m just trying to avoid paparazzi.”
Sans’s white eye-pupils widened slightly as he finally recognized your face from the massive billboards downtown “holy sh—you’re them. huh, guess the universe really does have a twisted sense of humor.”
You laughed, as Sans reached out his hand for you to take. “come on, popstar. let’s get you outta the soup store”
Underswap (Blueberry) 🫐
Blueberry was having a fantastic shift. He loved making pastries, he loved talking to customers, and he loved being the Magnificent Sans! He was currently wiping down the counter, softly humming the chorus of your latest hit song.
The bell above the cozy cafe door chimed, and Blue immediately brightened, wiping down the counter with frantic enthusiasm “WELCOME TO THE STAR CAFE! HOW CAN THE MAGNIFICENT BLUEBERRY HELP–” Blue choked on his own breath.
You walked up to the counter, pulling down your face mask just enough to order. “Hi there, can I just get a matcha latte and a cinnamon roll to go, please?”
“M-M-MY IDOL?!” Blue squeaked, his hands shaking so hard he nearly dropped his rag, stars literally formed in his eye sockets.
You winced slightly, looking around to see if anyone heard “Shh, please,” you giggled, putting a finger to your lips “Just a normal customer today, okay?”
“YES! OF COURSE! A SECRET MISSION!” Blue whispered loudly, and immediately clamped both hands over his mouth.
He quickly put your order together, and when he handed it over, you noticed he had drawn a perfect, adorable little frosting star on your cinnamon roll.
“Thanks, Blue,” you read his nametag, offering a genuine, sweet smile “You just made my whole day”
Blueberry stood frozen in place for a full ten minutes after you left, clutching his chest “THEY…THEY KNOW MY NAME…”
Underfell (Red) 🍫
Red was leaning against a brick wall, huffing on a cigarette and enjoying a rare moment of peace away from his brother. The muffled sounds of screaming fans echoed from the main street a block away, he rolled his eye-lights.
idol culture is stupid, he thought. people screaming over some pretty face.
Suddenly, the heavy metal door of the alley burst open. Someone sprinted out and tripped over a loose brick, stumbling right into his chest.
“whoa, watch it, sweetheart!” Red growled, catching you by the arms.
You looked up, breathless, your eyes wide with panic, you were wearing a glittering stage outfit, but you had a dark hoodie thrown over it “Please,” you gasped, looking back at the door.
“They’re coming. Just…act natural!”
Before Red could process what was happening, you grabbed the lapels of his fluff-collared jacket and pulled him down, burying your face into his neck to hide your features just as a horde of screaming fans sprinted past the mouth of the alley.
Red stiffened completely, his face instantly erupting into a bright, furious crimson blush. He could smell your expensive perfume and could feel your heart racing against his ribs, when the crowd finally dispersed, you pulled back, flushing a bit yourself.
“I am so, so sorry,” you breathed. “They broke through security, thanks for–”
Red stared at you, his sharp fangs bared in a stunned grin “you’re…you’re that pop star” He whispered to himself as cleared his throat roughly, trying to regain his tough guy demeanor while his face was still burning.
“heh, don’t sweat it, doll. hut, uh if you’re tryin’ to pay me back for savin’ yer skin…an autograph wouldn’t hurt.”
Swapfell (Blackberry) 🍇
Blackberry prided himself on his sophisticated taste, which was why he was currently hiding in the back corner of a vintage comic shop, aggressively flipping through a rare graphic novel, he was so engrossed that he didn’t notice someone standing right next to him, reaching for the volume above his head
Your fingers slipped, and the heavy omnibus tumbled down, smacking him right on his skull.
“WATCH IT, YOU WORTHLESS–!” Blackberry snarled, snapping his gaze up, purple magic flaring around his hands.
“I am so, so sorry! It slipped!” you gasped, pulling down your face mask to apologize properly.
Blackberry’s breath hitched, the purple magic vanished instantly. He looked at the comic in his hand, then at you, realizing he was currently holding the exact sci-fi series you had mentioned loving in your latest magazine interview.
“YOU…YOU’RE…” Blackberry swallowed his pride, a dark purple blush creeping across his face. He quickly straightened his posture, clearing his throat arrogantly to cover his panic.
“AHEM. IT SEEMS YOU HAVE TASTE, HUMAN. I SUPPOSE I CAN FORGIVE A MINOR ASSAULT IF YOU…SIGN THIS VOLUME FOR ME.” He states, causing you to chuckle.
“DO NOT MAKE ME ASK TWICE.”
You smiled warmly “I’d love that.” (He was internally screaming).
Ink 🎨
Ink was sitting on a park bench, swinging his legs back and forth, holding a sketchbook and a giant pencil. He was frustrated, having just taken a vial of emotion, but he just couldn’t find anything inspiring to draw today.
Everything felt…ordinary.
Then, you sat down on the other end of his bench.
You sighed, taking off a pair of heavy headphones and letting yourself enjoy the breeze. The afternoon sunlight hit you perfectly, casting a soft, golden glow around your silhouette. Ink’s eye-lights instantly shifted—one became a green diamond, the other a pink star.
Without a word, his hands moved at supersonic speed. He began sketching furiously, capturing the slope of your shoulders, the tilt of your head, the way your eyes looked so beautifully tired yet resilient.
“Um…excuse me?”
Ink blinked, realizing you were now looking right at him, an amused smile on your face “Oh! Sorry! I didn’t mean to creep you out! I just—whoa, wait, you’re the person from the big colorful music videos!” Ink gasped, dropping his pencil “I love your colors!”
You smiled, leaning over to look at his sketchbook and gasped, it was a breathtakingly beautiful portrait of you, surrounded by splashes of colorful ink “Wow…this is incredible, you’re amazing.”
Ink’s face flushed a rainbow of colors, he grabbed his scarf, hiding his mouth. “You think my art is amazing? Then can…can you sign my sketchbook? Please?!”
Error 🧶
Error hated public spaces, he hated anomalies, but more than anything, he hated the fact that your new album was a physical-only release and he had to go to a store to get it.
He stood in the music aisle, using his blue strings to delicately lift the last limited-edition CD off the shelf so he wouldn’t have to touch it.
“Oh, awesome! You found one!”
Error glitched violently at the sudden voice, his yellow ‘ERROR’ signs flashing across his vision. He spun around, ready to string up whoever dared speak to him,
Only to find you smiling warmly at him.
ERROR: WINDOWS_NOT_RESPONDING
“Oh, sorry! You can have it,” you said gently, amused by his rigid posture “I can just sign it for you, if you’d like?”
Error’s soul practically leaped out of his chest. “Y-YoU…tHe pOpStAr…s-sIgN iT?!” He snapped out of his crash, grabbing a sharpie from his pocket with a trembling, glitching hand, fiercely denying the massive yellow blush covering his face.
X-tale (Cross) ❌
The backstage area of your stadium tour was a hectic maze of security, dancers, and tech crew. Cross, who had somehow managed to get hired as a temporary security guard just to be close to the venue, was standing at attention near your dressing room, looking stoic and intimidating with his massive jacket and intense gaze.
The door flew open, and you stumbled out, tripping over a rogue stage wire.
Before you could hit the floor, Cross caught you, his reflexes were flawless, wrapping a strong arm around your waist, you looked up to meet his mismatched eye sockets.
Cross completely lost his composure. His purple blush flared up to his pinpricks. “I—uh—forgive me! Are you unharmed?”
“I’m totally fine, thanks to you,” you smiled, leaning against him for a second to regain your balance “Nice saves aren’t in your job description, are they?”
“For you, it is,” Cross blurted out, before realizing what he said, he quickly let go and stepped back, his face burning.
You laughed, hearing your name being called before planting a quick, thankful kiss on his cheekbone. “Then may I know my savior’s name?”
“Cross,” he choked out.
“Thanks, Cross! See you after the show!” you called out, running toward the stage. Cross stood there, completely paralyzed, a hand hovering over his cheekbone while Chara laughed hysterically inside his head.
Dream 💫
Dream loved walking through the city. The positive emotions from people hanging out after work always filled him with warmth, but tonight, he found himself stopped dead in his tracks in front of a department store window.
There was a massive, life-sized poster of you advertising a new fragrance. You looked like an ethereal deity, surrounded by glowing flowers.
Dream was completely entranced by the sheer aura of pure, golden positivity and joy you radiated just through your image.
“I look kind of ridiculous in that, don’t I?”
Dream gasped, spinning around. There you were, standing right next to him, sipping a smoothie. You were wearing a big scarf and a beanie, but those beautiful, expressive eyes were unmistakable.
“N-No! Not at all!” Dream stammered, his golden eye-lights turning into literal stars, his crown practically gleamed with his sudden spike of nervousness “You look absolutely stunning! Your energy…even on a piece of paper, you bring so much happiness to people! I can feel how much love you put into your work!”
You blinked, taken aback by his poetic and deeply sincere compliment. A soft, genuine blush dusted your cheeks “Wow, that’s…the nicest thing someone has ever said to me.”
Dream smiled softly, his hands clasped together “You may call me Dream”
You smiled back, reaching into your bag and pulling out a small, metallic star-shaped pin, pinning it to his cape. “Nice to meet you, Dream.”
Nightmare 🌑
Nightmare preferred the quiet, rainy nights in the city, the ambient negativity of tired commuters fed him. He was strolling down the central plaza, his tendrils swaying lazily behind you, until he noticed a figure standing by a fountain.
You were softly singing a melancholic melody to yourself, looking stressed from your heavy idol schedule.
Nightmare paused, his single cyan eye widening. He knew your songs, in fact, your rare melancholy tracks were the only things he tolerated listening to in his castle.
“You’re making a lot of noise for someone who is supposed to be a professional singer.” He stated, catching your attention. You look at him, not even scared of his intimidating, gooey appearance “Just practicing, was I disturbing you perhaps?”
He scoffed, crossing his arms. “Whatever, don’t lose your voice. It would be a waste of a decent instrument”
You softly smiled at his words, noticing the concern behind it “Do you mind the company?”
Nightmare scoffed, a rare, genuine softness crossing his features as he sat down by the fountain “Do what you want. Sit, I’ll make sure no one bothers you tonight”
Dusttale (Dust) 🌪
The local library was dead quiet, which was exactly how Dust liked it. He was sitting in the back corner of the history section, his hood pulled low, muttering softly to the ghost of his brother that only he could see.
“paps, shut up, i’m trying to read…” he whispered aggressively.
“Excuse me? Do you know where the music theory section is?”
Dust snapped his head up, ready to glare the intruder into submission, but the words caught in his throat. You were holding a stack of notebooks, looking slightly lost, Dust’s purple eye lights flickered erratically.
He recognized that voice, he listened to your songs on loop during his worst nights.
“u-uh,” Dust stammered, his usual creepy demeanor evaporating. He pointed a shaking, gloved finger toward the next aisle “t-two rows down. on the left.”
“Thank you so much cutie!” you whispered with a warm smile before walking away.
Dust slumped into his chair, his face a bright violet. See, Paps? he thought frantically. I told you they were real! She spoke to me!
Killer 🔪
Killer was leaning against a brick wall outside a concert venue, flipping his knife casually. He didn’t care much for society, but he had managed to snag a ticket to your show because your chaotic, high-energy pop anthems honestly scratched a very specific itch in his brain.
You exited through the back door, flanked by a few crew members, heading toward your tour bus, you walked past him, catching sight of the unique, dripping black lines beneath his eye sockets.
Stopping in your tracks, you looked right at him. “Wow, those lines on your face are incredibly cool. Is that stage makeup, or a tattoo? It looks amazing on you!”
Killer froze, the knife slipped through his fingers, clattering loudly against the pavement. His soul rattled in his chest while his standard, manic grin melted into a wide-eyed, blushing mess.
“I—uh—wha?” Killer stammered, a dark red blush spreading across his skull. “You…you think I look cool?”
“Definitely!” you smiled, before hearing your name be called. You start to wave goodbye as you stepped onto the bus. “Have a good night!”
Killer stood there for a full ten minutes after the bus pulled away, clutching his cheekbones. “She liked the murder streaks. Paps, she liked them.”
Horrortale (Axe)🍴
The “All-You-Can-Eat” buffet was chaotic, but Horror didn’t care. He had a plate piled three feet high with various meats, his large, singular red eye scanning the room hungrily.
He sat down at a secluded booth, ready to dig in, when a shadow suddenly appeared beside him.
It was you, wearing a heavy disguise, trying to eat a quiet meal away from the fancy restaurants your manager always forced you into, you looked at Horror’s massive plate, then at his intimidating appearance, and smiled.
“Dang, nice haul. Making your money’s worth I see,” you said, holding up your own plate of comfort food.
Horror stared as his jaw dropped, showing off his sharp, jagged teeth. A deep crimson blush spread across his cracked skull, he recognized you instantly, the head chef at his mansion always played your music in the kitchen.
“Y-You…” Horror rumbled, his voice deep and gravelly, he looked at his plate, then suddenly lifted the entire mountain of food toward you “Want some? Good meat, for the star.”
You laughed softly, touched by the gesture. “Well my manager did say I can eat properly today…Mind if I join you so we don’t eat alone?” Horror’s soul practically melted, he nodded eagerly, moving a bit to let you sit down.
You dig in as he looked at you like a giant, protective puppy, thrilled to be sharing a meal with his favorite star.
Epictale (Epic) 😎
Epic was currently leaning over a glass display case, staring intensely at a giant, multi-layered chocolate mousse cake. “bruh,” he muttered to himself “that cake is lookin’ sub-lime. an absolute masterpiece of the culinary arts, bruh.”
“I know, right? I’ve been staring at it for five minutes.”
Epic turned around so fast his purple trench coat flared out. Standing right next to him was the absolute leader of the pop charts, you were wearing a stylish beret and looking at the cake with the same intensity he was.
Epic’s eye-lights dilated, he smoothly adjusted his coat, leaning against the counter with a sly grin. “well, well, well. if it isn’t the star of the show, bruh. what’s a famous idol doing in a humble bakery like this? looking for some sweet inspiration?”
You laughed, recognizing him from his viral internet videos. “Exactly. I heard this place had the best chocolate mousse in the city”
Epic’s soul practically soared into the stratosphere. He slammed his hand on the counter “shopkeep! give us the whole cake! put it on my tab, bruh!” He turned back to you, winking. “only the best for the finest voice. come on, let’s go destroy this cake bruh.”
You giggled, linking your arm through his “Lead the way.”
Fresh 🌈
Fresh was in a abandoned alleyway, actively spray-painting a massive, neon-colored mural on the brick wall. He was rocking his usual ‘90s attire, his ‘YOLO’ glasses reflecting the bright pinks and greens of his art.
You happened to be taking a shortcut back to your hotel when you spotted the mural, you stopped, genuinely blown away by the creativity.
“Wow, this is so cool!” you exclaimed “The color blending is insane, you’re a seriously talented artist.”
Fresh spun around, his skateboard clicking against the ground, behind his sunglasses, his parasitic eye lights swirled.
He knew exactly who you were—your face was plastered on every digital billboard in the city, the epitome of modern ‘cool’.
“whoa, chillax, un-brah! you’re the main attraction! the mega-star!” Fresh said, his glasses changing to spell “OH” “MY”.
You laughed as a neon purple blush appeared on his cheekbones, he pulled his glasses down slightly, peeking over them “you think my art is fresh, star-child?”
“I love it,” you smiled, taking a selfie with the wall (and him) in the background.
“brah…my art just got certified by the highest authority of cool,” Fresh muttered, throwing his spray can in the air and catching it, a huge, dorky smile breaking across his face.
“Can I try?” you asked, pointing to a spare can.
“aw snap, an idol collab?!” Fresh handed you the neon pink spray can with a grin. “let’s make this wall look totally bomb-diggity, old sport!”
ARGHH WE NEED MORE UNDERTALE AU FANFICSS, I did not like how I wrote Nightmare and I swear I’ll make Dust longer next time. Is this fandom still alive? Lemme know wht to do nextt
Imagine telling them that you're pregnant and how will they react?
Sans:
He's gonna be a father? He can't believe it... He didn't even know humans and monsters could reproduce. Uh what does he do? He's not totally clueless on how to tke care of a kid... it's just a human baby he doesn't know. Lucky you are a human (obviously) and can help him. Yeah, he raised his little brother, but he still felt like he was gonna be a terrible father. Although Sans will stop be lazy at times for you and help you, so you don't hurt yourself or the unborn child. He didn't care if the child was human or monster. He would love them nonetheless. "Sans I love you so much but you will be the best father." "heh... yeah i hope so... i love you too"
Papyrus:
THE GREAT PAPYRUS IS GONNA BE A DAD?? He cannot wait. Absolutely will start researching just like a few other skeletons looking at everything he needs to know about you being pregnant and when the baby is born. Expect long evening s with him. He's quite an active skeleton but he'll do his research and let you snuggle against him. He realizes that you need rest and a lot of it! He will remind you of upcoming appointments you need to go to. He will be the best father ever. He is The Great Papyrus after all. "Sweetheart we don't need all of this..." "YES WE DO I READ IT IN RESEARCH ABOUT FOOD CRAVINGS... WE MUST GET ALL THIS FOOD."
Red:
What did you just say? Your... pregnant? He's happy to have a kid with you but definitely out of everyone he feels the most unprepared to be a dad. He didn't come from the best life and is scared. He doesn't want the baby to grow up like he did only knowing 'kill or be killed' Que in protective Red. He makes sure you don't eat anything you're not supposed to. He reads up about human pregnancies for some help and of course asks you his gorgeous s/o. You will always be taken care of by this secret softie. "Red babe... how many times do I have to tell you that everything will be okay?" "uh.. yea' i know it will. just worried..."
Edge:
He's shocked like some other skeletons. He's happy to have a child with you. He will raise them to be strong and mighty and not fear anything! But for right now the baby is still inside you... for another few months. He'll schedule you any appts you need ultrasounds, prenatal to talk to your doctor or midwife. He will make sure all of your cravings are satisfied no matter how weird they can be! He can sense your anxiety when your anxious about something, so he'll happily help you if you need it. "AH YES WHEN OUR BABY IS BORN, THEY MUST WEAR THIS!" "Baby... we are not putting a collar on our newborn child..." "AND WHY NOT? A COLLAR IN MONSTER TERMS THAT THEY ARE PROTECTED!" "Papy... I'm not putting a collar on my newborn baby and that's final"
Blue:
He's so excited to be a father! He has experience thanks to raising his little bro Papyrus. Have you guys got everything? Diapers? Check! Bottles? Check! All the other essentials items needed? Check! He needs to make sure nothing goes wrong during your pregnancy. He's heard of the things that can happen when a human is pregnant, and he doesn't want them to happen. "Blue baby... I'll be fine carrying these inside..." "NONSENSE I MUST MAKE SURE MY PREGNANT S/O DOESN'T HURT THEMSELVES!"
Stretch:
He's gonna be a dad? His eye lights would instantly soften as he smiled. He's excited but doesn't exactly show it right away. He'll show it in his actions. Since he's naturally very caring expect him to ask every once in a while, if you need anything. He'll make a lot of dad jokes and stock up on snacks just for you. He loves ya and hopes his actions show that. Expect more cuddles than usual with his phalanges caressing your belly. He'll sing lullabies to your belly as he held it. Yes, he might not be the most energetic partner, but he'll be one hell of a father. "Baby...? what are you doing?" "oh, you know just humming... a lullaby to my baby.."
Bear:
He'll be a little quiet for a bit at first. He's not sure what to say. He's happy and will show in his actions. Throughout your pregnancy you'll find more baby items appearing in your guy's house. If you get discomfort or cravings, he'll give you anything you need. He's more anxious than others and may get anxiety hearing all the bad things that can happen during a human pregnancy. He'll most likely get Papyrus's help building the nursery and crib. He doesn't have the best memory sometimes, but he'll always try his best to remember for you. "Sweetheart I have an appt to go to are you coming with?" "huh..? we have an appt to go to? uh.... yeah i always come don't i?"
Sweets:
He's gonna be a father? He can't wait! He's gonna make sure he gets everything you need for your pregnancy. He wants you to rest as much as you can and please sweetheart eat if you're hungry. He might've come from a world where food was a rarity but if you need anything he'll get you it. Just no sushi. Sorry. He'll build the nursery for you and crib. Expect this big guy to want to touch your baby bump almost every day to keep progress. He'll talk to your belly hoping the baby can hear their father's voice. He's invested for the long run. "DADDY LOVES YOU... SO SO MUCH... LITTLE MIRACLE" "Papy... our baby isn't here yet" "I KNOW... I JUST WANT TO TELL THEM BEFORE THEY'RE HERE"
Dream:
As being the guardian of positive feelings, he is overjoyed to learn that you are pregnant. He would offer any emotional support you needed. Need a hug? He's happy to give you as many as you need. Need some lovings? He'll give you everything you could ever need and want. You would watch him accidently knock over some items in the nursery you guys are making together. He doesn't mean to! He swears! He's just so excited! He's gonna naturally be protective over you and your guy's unborn child. "Dream... will I be a good parent to our child?" "Of course, sweetheart! I believe you will be... you're already the best s/o a skeleton could ever ask for..."
Nightmare:
He's completely shocked. He didn't know a... child could happen but as soon as he knows he gets protective. Welcome in protective Nightmare! Most protective of them all in my case. If Nightmare can't be around then his second closest skeleton he trusts most, Killer is standing nearby you and protecting you. Nightmare makes sure to do his research about human pregnancies after he learns about you being pregnant. He makes sure you get all the rest you need and eat healthy. "dear... what did I say about not too much?" "I'm sorry Nightmare... I just wanted to make myself some food." "couldn't you have made something at least healthier?" "No"
Ink:
He was super shocked and first. Now he's so excited that he ends up throwing up black ink. 100% he is going to have ideas of how to decorate a nursery room and even how to paint the walls. Yes, he can be a bit forgetful at times so you might need to remind his of upcoming appts. He's gonna be the best dad he possibly can be for your child. He's another one who'll be a bit protective over you and making sure you don't hurt yourself. He may not have a soul and need to drink paint to feel emotions. He loves and adores you so much and the same will go with your guys baby. "So.. what should we name the baby Ink?" "Oh! I don't know there's so many to choose from!"
Error:
How and when? Just like classic Sans he didn't know that humans and monsters were compatible. Error doesn't really like being touched a lot so how did this happen between you and him? Well, you're special to him. It took a loooong time before you and Error were physical with each other. Error may be evil but once he learns you're pregnant you're staying with him. No, you cannot go to other AU'S to talk to the other Sans and Papyrus's. Ink may be able to visit but Error is standing close by making sure nothing ever happens to you. He treats you like your glass that'll easily break. "Error... please? I wanna go see the others" "No... YoU'rE mInE... gOtTa PrOtEcT oUr LiTtLe OnE"
Nova:
Acting similar to classic Sans. He's gonna joke around a little more. He can't wait to have a mini him or a mini you running around. He'll start baby proofing the house very early on. He'll joke about sleeping in the nursery. Anything you need from the store? He'll go and grab it for you! He'll read into prenatal things you need. He's not a public display kinda skeleton more private. He'll buy baby clothes for you if you're feeling a bit emotional! He's there for you always and always will be. "what if i mess this up... bein' a father i mean?" "You won't Sans... i just know you won't. You'll be the best dad ever"
Apollo:
He's gonna have a baby! Expect this skeleton to come up with stellar baby names to name your baby. Callisto? Juno? Sol? Orion? All the names he can think of will be named! He'll make baby blankets and clothes to match his outfit. Are you hungry in the middle of the night? That's alright he'll wake up and grab you something! Another skeleton that'll talk to your belly. This baby means everything to him just like you do! He will protect you and your future baby from any cosmic harm or any threats at all. "Baby... are you make another outfit...? We already have 10.. and the baby isn't even here yet." "WE CAN NEVER HAVE TOO MANY MY LOVE!"
Nox:
Now Nox would be a little rough on the outside. Being like kids? Just what I needed. He promises he means no harm by what he said! He does care and he can't wait to have a kid with you. Once he's over the surprised part he'll get protective seeing the world he came from. He had to protect his little brother Rus from other monsters. Hey! Where do you think you're going alone? If you plan on going to the store alone that isn't going to happen anymore. Nox will be beside you at all times. He'll do what he needs for you making sure everything he's doing is right. He might've needed to look up at times how to handle his pregnant s/o mood swings. "BABY I THINK YOU ARE OVEREACTING... ITS JUST BABY CLOTHES" "B-But... look how small they are... I have a baby inside me" Cue the crying s/o as they look at small baby clothes.
Rus:
Your pregnant? Are you sure... like really... really sure? This poor skeleton is gonna be even more anxious now that he has to worry about his pregnant s/o. He loves them so much and doesn't want anything bad to happen to them. He's always asking can he protect you and his future baby? Hell, he was sheltered by his older brother Nox when they were still underground. He's still learning some independence. Will he a good father to your guy's baby? He will buy any baby clothing that he likes. Makes sure you have absolutely everything you could ever need. Even though you might not even use 75% of it. He isn't sure how to be a father, but he'll try his best for you. "mine... you and the baby are mine... i don't want anything to ever happen to you two" "Aw.. we both love you Rus.."
can i request some general relationship headcanons with swapsans and a reader who’s just really airheaded/clumsy and forgets a lot by accident? she’s just so in her head, a million thoughts bombarding her at once, that she can’t help but tune out the world!! give her a break </3
thank you 🙏
SF! And US! Sans with airheaded s/o!
(not one of my favorite writers, following and REQUESTING from me! *Freaks out in the corner of the room* anyways hold you like it! Art not mine! I did both swapfell and underswap btw lol!)
Blue
Okay so of course before you start dating, you're friends with him so blue already knows about all your little 'quirks' so to say. Once you start dating though he'll start paying more attention to them. For when you're clumsy, he'll start putting those plastic tabs on the corner of everything that has a sharp end, like the table. Or he'll make premade meals for you so that you don't attempt to cook if he isn't home, something you can just put in the microwave. He also buys a special knife for you, like one of those plastic kid safe ones.
Now since you're forgetful, he'll start leaving notes for you everywhere. Reminders for things, times to eat, medicine if you take it. Even notes about how much he loves you! If you don't understand something, blue will explain it to you in a way he'll know you'll understand. You also probably do understand half of stretches jokes, but he doesn't want to explain those to you. That way you both don't have to suffer from puns.
"STAR, DID YOU REME-, OH SO YOU SAW MY NOTE, GOOD!"
Nox knows immediately when you are spacing out, he doesn't mind that you do it at all. He knows that you have a lot on your mind and are always overthinking stuff. However if you are doing it in the middle of something important or something dangerous that could hurt you, he will snap you out of it. Usually nudging your side gets you to snap out of it or just saying your name, if that doesn't work he'll pinch you softly.
Nox is a live you learn type of guy, so at first he thinks you'll learn from being clumsy all the time. Once he realizes, you're not going to, well he starts to take little precautions here and there for you. Though not too many because he doesn't want to treat you like a child. Also one to leave notes for you, once again not as many but ones he knows are important. Maybe a special one once and a while. He'll also double check that you found his notes at the end of the day, just so he knows you got done what you needed to.
Note: "DARLING MAKE SURE TO CHANGE THE LAUNDRY OUT AND TO FOLD THE CLOTHES ON THE BED! MAKE SURE TO EAT ALSO!"
Sorry, I meant to send an ask yesterday, but I got carried away 😅
So what about ut, us, uf and ht (you can ignore the last one if you want to don't worry) and how they would be with a reader that hides the fact that they're physically hurt.
Maybe they went hiking with the skellie, and they tripped and pretended that it was only a little scratch when days later they see quite a big wound that's infected.
It's a bit gross, so it's okay if you don't do it, don't worry :)
Have a good day/night and be safe

UnderTale, UnderSwap, UnderFell, and HorrorTale skellies react to a reader hiding that they're injured
you had gotten in a little tussle with a fallen branch walking home. you were completely oblivious, and tripped right over it. it hurt to walk on, and you soon noticed it swelling. it wasn't... sprained, right? nah, of course not! you brushed it off, thinking that it would be just fine in a day or two.
but until then, you might want to put some ice on that.
and so you did. for three days, with no sign of improvement. you tried keeping it a secret, but then your s/o came home while you were putting ice on it, right on the couch beside the door, and...
UnderTale:
Sans:
-he walks into the house, immediately heading for the couch.
-"hey, y/n, i'm ho- you alright? what happened to you?"
-"oh! sans, hi, i didn't expect you home so early!" you wave frantically to draw his eyes away from your ankle.
-"yeah... work was slow, so i came home. whats going on? you're acting weird."
-"pshh, don't be silly, nothing's wrong! absolutely nothing!"
-he sighs.
-"my whole shtick back in the underground was that i can see peoples stats. your HPs lowered, you're acting really awkward about your leg, and you're trying to hide an ice pack from me. i know, i saw it when i walked in. so, im gonna ask you again. whats going on?"
-you sighed. he caught you, he always did.
-"i dont know what's up. I tripped a few days ago and my ankle just started swelling. I'm gonna give it a few more days before I see a doctor, just to see if it heals on its own."
-"alright then," really? that's it? not going to insist you see someone? well, that's great for you! "I'm going to grillby's. wanna come?"
-you nodded your head.
-"cmon, let's take a shortcut."
-he took you to the fucking ER.
Papyrus:
-you look up after hearing the door open and you heard a crash.
-he had gone grocery shopping, apparently, because his bags were sprawled on either side of him on the floor.
-his jaw was only half hinged, that's how bad you scared him.
-as in it dropped. almost fully.
-he suddenly runs to your side (re-hinging his jaw on the way) and kneels by your side.
-"HUMAN, what ever is the matter? is it serious? does it hurt? will it need stitches? should i take you to-"
-"Paps! i'm okay. i think it's just sprained, i'll be alright," you tries to reassure him.
-"SPRAINED? oh, HEAVENS no, i must take you to the doctor right away!"
-you sigh. "Papyrus, it isn't that big of a deal. i'm sure it'll be alright in a few days."
-"absolutely not! what if it's worse than you think? it could kill you!"
-he really thought a sprained ankle could kill you? he may be clueless about human injuries, but at least he cares!
-you don't have too much time to reply before he picks you up, puts you in the car, buckles you up (because heaven forbid something ELSE happen to you, ESPECIALLY under his watch) and brings you to the ER.
UnderFell:
Sans:
-he literally did not notice.
-he grumbles a quiet, "hey," before trotting upstairs into his room.
-it isn't until several days later when the pain has worsened and you cannot walk on it that he asks what the fuck is going on.
-you explained that you had tripped a few days ago, and it got swollen, and you thought that it would just go away, but it's been getting worse and worse since it happened.
-"fuckin' idiot," he groaned. "i'm dating a goddamn moron! alright, get in the car. i'm takin' you to a hospital."
-he's groaning the entire way.
Papyrus:
-as soon as he lays eyes on you, he sighs.
-"what did you do this time?"
-what the hell did he mean, 'this time'? he CANNOT be holding you accountable for that one time you got a concussion! that was HIS fault!
-"hey! you BETTER not be talking about-"
-"about the concussion," he cut you off. "yes, yes, i'm aware, you believe that incident to be my doing. however, i can GUARANTEE that this is not! now, tell me what happened. i expect a full explanation."
-you rolled you eyes and told him, feeling a little pissed off about his crossed arms and tapping foot, although you couldn't fully blame him. the whole situation WAS a little silly, now that you have to say it out loud.
-he scoffed when you finished talking. such a silly thing! why the HELL didn't you immediately see a doctor? swelling is NEVER normal!
-how did he, a skeleton monster who had gone most of his life without so much as seeing a human, know more about human anatomy than a fully grown human adult?
-and how did he, an esteemed member of the royal guard, end up in a relationship with such a fool?
-"get yourself looking decent. we are visiting the hospital to get you proper treatment."
-'looking decent', you looked fi-! no, you didn't, nevermind.
UnderSwap:
Sans:
-"hey, y/n, Alphys let out training early, so i'm back! what are you doing?"
-you scrambled to hide the ice pack and hike your pants back over your ankle. "oh, uh. . . nothing," you said sheepishly in reply, a fake grin appearing on your face.
-"oohhhh, no no no. i know that look. you're hiding something. best be honest now."
-damn him! how DARE he know you so well!
-"i think i did something to my ankle," you muttered.
-"hmm. . . let me see."
-he walked over and inspected your ankle for a few moments.
-"it looks sprained. when did this start?"
-"a few days ago. i tripped and it started swelling."
-he gave your ankle ankther quick look.
-"and why didn't you tell me?"
-"well, i thought it would go away at first. i was going to tell you, if it didn't. i was just going to wait a few days."
-"well, there's no need! i'm taking you to a doctor."
-he helped you stand and let you use him as something like a crutch, so you wouldn't have to put too much weight on your injured foot.
Papyrus:
-you look up to see him standing, eyebrows furrowed (you know what i mean sans does it in the main game) looking at you.
-"anything you want to tell me?"
-"ah, nothing. . . i'm just gonna go to a doctor if this doesn't start getting better."
-you knew the look he was giving you. he wanted to know what happened.
-"i tripped a few days ago and my ankle started swelling. nothing major. it's just a little sore."
-"mmm. i'm sure. you have five minutes, then i'm taking you to a doctor," he said as he laid on the couch beside you.
-"no, Paps, there's really no need-" you were interupted by snoring. but you knew that didn't mean you were off the hook. he would be awake in five minutes EXACTLY, whether you were ready to go or not.
HorrorTale:
Sans:
-he kinda just stands there for a few moments after he sees you with the ice pack.
-ice pack means something's wrong, because he doesn't see food around, but his skull injury makes figuring anything else out difficult.
-ice pack. . . on your ankle. . .
-it doesn't matter what's wrong. he just knows something is. so, he comforts you! in the only way he knows how!
-which is a BONE-CRUSHING hug.
-and because you're sitting, and he's standing over you, leaning down to hug you, it's a very awkward angle. leading to a lot of bones jabbing into uncomfortable places.
-you know you can't really do anything to get him off of you, so you just wait it out.
-"i'm alright, Sans. it isn't anything major. i'm about to go to a doctor!"
-he was going to tell you to anyway. you just got that part out of the way.
-his time in the underground under Undyne's rule made him very paranoid about the health of those he loves, so no matter how big the injury, you MUST see a doctor.
-it's not up for debate.
-he drives you because he doesn't want you to have to put any more strain on your ankle.
-(should he even have a drivers license? questionable...)
Papyrus:
-he has a puzzled look on his face.
-that. . . he suspected that wasn't a good sign.
-"y/n. . . i don't suppose you want to tell me what is going on?"
-"oh," you nervously laughed. "no biggie. just tripped a few days ago, it kinds hurts. if it doesn't feel better tomorrow i'm seeing a doctor."
-"hmm. i shall hold you to that."
-you laughed. you bet he would.
-spoiler alert, he did.
(a/n: sorry if this is totally inaccurate to having a sprained ankle, it just seemed like a good scenario, and i was too in the writing groove ((once i actually started)) to do much research)
I said I was gonna go to sleep but apparently I am a liar and a fool
SO!!! Reader insert dating headcanons with my swap guys and my swapfell guys :) These are my personal AU interpretations !!! so don't get mad at me if they don't line up with common fandom lore.
You can see more of my guys here (for swap) and here (for swapfell)
Larimar (Swap Sans) is the type to realize immediately that he's in love. He isn't stupid and can fully pick up that his feelings towards you have changed, it's the confessing part that he has trouble with. He's still a Sans, so he still has SOME issues with dealing with feelings and how to process and speak them. He doesn't have a big planned out confession or an ultimate romantic date where he confesses. It just slips out during a domestic moment or while you two are having fun.
While I wouldn't say he has a fetish for humans, he does have an extreme interest in how humans work. This makes him especially touchy and also causes him to watch you do basic tasks with a dopey love struck grin. He's especially fascinated watching you eat, watching the muscles flex and work under the skin, if it creeps you out he'll try to stop but he still ends up staring a little.
Lars isn't really the jealous type. He's confident in you and the trust you both have so he isn't at all worried. He does, however, get possessive if somebody tries pushing your boundaries and what you're comfortable with. He was formerly the Captain of the Royal guard, so he does know how to be intimidating and demand respect (even if he doesn't use that skill often.)
You getting along with his brother is an absolute must!!! He is aware that his brother is... odd at times, and he doesn't really understand what questions are rude and what questions aren't, so you at the very least have to be able to be in the same space for a few hours without killing each other. If you get along with his brother that's even better!
Regardless of your height or weight he will 100% carry you around. He trained EXTREMELY HARD to be Captain and he sure as hell won't let his training go to waste! He'll carry you bridal style, fireman style, or even under his arm like a sack of potatoes.
Larimar's ideal date is an observatory! While stargazing is nice, an observatory tends to be a little more interactive.
Clay (Swap Papyrus) doesn't realize he has feelings until they're either pointed out or it hits him in the middle of another task. Once he realizes those feelings he reanalyzes every interaction you've ever had with him to pinpoint when it happened. He confesses casually, no flare or pizzazz. Hell you'd probably barely even notice it if it didn't come out of left field.
Clay is kind of weird when it comes to actually being in a relationship. While he's open with his emotions he's not exceptional at picking up yours. It's a relationship that involves a lot of communication about things that might upset you, you can't just huff around and expect him to know whats wrong or even pick up that you're upset because of him.
Clay isn't jealous at all, nor is he really possessive in any way. He'll step in if somebody is bothering you but its more in a casual "we may or may not be dating" way. He's not super into PDA either but holding hands or having his arm around your shoulders is fine, though he does have a preference for hand holding so he can feel the joints under your skin (he is 100% stimming).
He does want to have Lar's approval before the two of you can actually date, mainly because he knows Lar's is a good judge of character and while Clay believes he's a good judge it never hurts to have an extra pair of sockets looking out for him. You getting along with Lars is either the best case scenario or worse case scenario depending on how many puns and shitty jokes come out of it.
Clay actually really enjoys cuddling, especially if you lay on top of him. He isn't fragile so don't even worry about putting your full weight on him, you're just a really warm weighted blanket. You WILL relax and take a nap with him.
His ideal date is the Aquarium but specifically the underwater tunnels with seating, so you can both just watch the fish go by.
Charoite (Swapfell Sans) is the type to realize he has feelings, come to terms with it, and then ignore it. Hell he never actually confesses. He just wakes up one day and you're sharing a bed and a life together and he goes "Wait a fucking second." Big "do you like me" "we've been married for 10 years" energy in this guy.
Charon likes to make sure you're well fed and taken care of. He'll neglect his own health (often on accident) but he ensures both you and his younger brother are healthy. This ranges from making sure you have breakfast, lunch, and dinner, to reminding you to take a shower or a bath. He is extremely good at balancing greasy indulgent foods with healthy foods, so your meals are always enjoyable.
He's a little bit on the jealous side, though that can be attributed to his life underground, where having a defined romantic relationship often ended in tragedy unless you both were powerful. He tries not to let the jealousy win over reason, but if somebody ignores your boundaries even once they are on his shit list. Possessive as fuck when somebody is trying to flirt with you.
While he loves his brother, he is fully aware that his brother would probably remain uncomfortable around you for a long while. Charon uses his own judgement to decide if you're someone to keep and can get along with his brother or if he should cut his losses as soon as possible. If you do end up getting along he is over the moon.
Charoite loves affection, but any kisses on his face should only be given to the side of his face he actually has feeling on. While he understands the empathetic need to kiss his scars, he'd prefer the kisses be somewhere he can feel them. He also adores nuzzling into you at any possible moment, reputation be damned.
His ideal date is stargazing with a picnic. He's used to constantly being stressed and on the go so something relaxing and low energy is fantastic.
Rust (Swapfell Papyrus) is the type to be afraid to realize and commit to his own feelings. Once he accepts them, however, he'll confess in an extremely romantic way. He's anxious and might be shaking a little while doing it, but he wants to do it properly.
Rust is more of a landscape and environmental artist, but started branching out when he arrived on the surface. He often draws your face specifically in an attempt to get past his face blindness and commit you to memory. It hasn't worked so far, but he's hoping it will someday. Regardless of his ability to remember your face, he has your scent memorized to SOUL.
Rust is absolutely on the jealous side. He's always been an outlier Underground in that he was more passive so once he has something important in his claws he's not letting go. He still tries to keep it under control, but if he even smells the slightest romantic intent from somebody else towards you he'll get possessive. He does try to keep that under control as well, but half of the humans that approach you that way smell absolutely foul and he just can't help himself from resource guarding.
He absolutely wants his brothers approval when it comes to dating you, but is also willing to argue with him. He trusts his brother's judgement but is also well aware of the fact Charoite doesn't trust easily or willingly. It'll be a long long string of awkward family dinners before things relax.
Rus HATES PDA. It makes him extremely anxious and it makes him feel like literally everybody is staring, though this is a bonus when he's feeling possessive. In private he's practically glued to you, hanging off you or playing with your hair or clothes. He is touch starved and even just sitting next to you on the couch makes him happy.
His ideal date is going to the beach or a lake, where he can draw both the scenery and you.
