Um Hello, Could I Request Undertale Sans Relationship Headcanons With A Female Half Angel Half Human

Um hello, could I request Undertale Sans relationship headcanons with a female half angel half human reader? Sfw and nsfw, please and thank you! Hope you have a great day.

Hi! Thanks so much for being my first request I got so excited I had to tell my whole family as soon as I saw this in the inbox lol. I don't know a lot about angels but I had fun with this! I hope you enjoy ::3 NSFW under the cut!

SFW:

•Sans loves your wings he thinks they're gorgeous and would love to help you preen if you're comfortable with it, he's gentle and can reach all the spots that are hard for you to get to.

•He loves seeing you in white and gold, he thinks it makes you look even more angelic and it's a quick way to have him staring at you with a blush and dopey smile until you mention it to him and he busts out the angel puns.

•He enjoys having your arms and wings wrapped around him when hugging or cuddling. It makes him feel extra loved.

•PLEASE take this man out flying to see the stars. It's the perfect date idea and it's probably the closest to the stars he's ever been. Quick way to get this man to think of marriage lol.(Okay this is so cute I gotta write a small drabble ur being blessed today)

You chuckle as Sans clings to you.His face pressed against your chest. Currently you're flying over Ebott city with your bonefriend in your arms taking him to a supposedly special date you had set up. You called out to tell him you're almost there, having to yell over the wind howling. Once you escape the city and more importantly the light pollution you yell for Sans to look up. He does and his eyelights expand to almost fill out his sockets. His grin falters and he looks shocked before his entire face lights up. You think he says something but his baritone voice is hard to hear over the wind. He reaches a hand up as if he could reach out and touch the stars. You chuckle again and he says something else so you yell that you can't hear him. He leans up in your embrace and says in your ear

"i love you starlight" you smile as he kisses your cheek. He watches the stars as you approach as hill and land, the next few hours are spent stargazing with sans as he points out constellations and tells space puns.

•He has a dreamcatcher made with your feathers. He kept a few after helping you preen once and after finding out what dreamcatchers were he thought it would be a nice reminder of you when you're not around.

NSFW:

•He gets worried about hurting your wings a lot when boning so he normally prefers for you to ride him, he also really enjoys the scene of you cumming on his cock your wings stretching to their full glory from the orgasm. It's a sight to see.

•The uncommon position switch normally has you in doggy style. There was one time where Sans came so hard he grabbed onto the scapulars(base) of your wings to brace himself. He thought it was extremely hot to use them as handlebars but was so worried he had hurt you.

•Body worship, it just feels right for him to worship you a little. You're just so angelic and perfect to him he wants to do all of it kissing up your legs, massaging your back and wings, running his fingers through your hair as he kisses you. He just loves you so much and he's going to make sure you feel how much he does. It's one of the few times he really puts effort into something.

•Feather play, Imagine him dragging your own feather across your thighs and teasing your nipple with the tip of one as he squeezes your other breast. Sometimes he'll just tickle you during sex, pelvis deep inside you and this man has a feather tickling your sides cause he thinks your laugh is hot.

PDA with UT,UF,US

Hi! This one was fun they're a little short but oh well. I struggled a little but that's part of what made it fun! I have some longer drabbles planned soon so woo look forward to those and enjoy!

Undertale:

Sans: Sans is alright with a little PDA. He's pretty laid back but won't really go farther than small pecks. He doesn't really feel like making out in front of people or anything like that but small quick kisses are okay. If it's a heat of the moment thing and the kiss gets a little heated that's okay just not an everyday thing and he's gonna be super flustered afterwards and beg you to go home. Loves to hold your hand and have you lead him around. Hugs are always welcome with this boy too.

Papyrus: He welcomes PDA and initiates it often in the form of hand holding and forehead kisses as that's the easiest to reach area for him. He loves any affection from you. He won't take it too far in public but it's not like he's gonna shut down some hand holding or a good ole kiss every now and then when you can reach.

Underfell:

Red: He adores PDA he's a pretty insecure fella and PDA is kind of a public announcement of hey this is mine to him he appreciates it a lot. Hand holding, kisses, grabbing/smacking your ass. He won't go too far if you're not comfortable with it. Please initiate some sometime he'll melt y'all.

Edge: Not a big fan. He'll hold hands and do cheek kisses and hand kisses the small stuff but nothing as big as an actual kiss. He's kind of a private person and is still unlearning that he needs to hide moments of softness.

Underswap:

Stretch: He enjoys PDA. Smooches, hand holding, hugs. He won't really initiate past hand holding and some light kissing but he's accepting if you want to go farther. Not like make out level. You might be able to get him worked up enough for that in public but it happens rarely.

Blue: I feel like he initiates it the most I'm going to be honest. He's the most stable and secure in his relationship so he has no problem just smooching ya out of nowhere people around or not. He might push you aside to somewhere more quiet if things get heated as he's not comfortable making out in front of people but long passion filled kisses slip through sometimes. He gets excited easily what can he say.

How they act when crushing UT,UF,US!

This one was fun I might do a part 2 eventually because I love how people change their behavior while crushing on someone think next is gonna be confession head canons or a drabble. Anyway requests are open! Just wanted to put that out there I love getting them ::> and I'm pretty open to writing most things I love getting different inspo from different people. Anyways I'm done rambling hope y'all enjoy!

Undertale: Sans: Trys to make you laugh as much as possible. He loves hearing your laughter and is super proud when he can get you to full on laugh with his shitty jokes. He's a daydreamer and often daydreams about you when it's slow at work or he's in bed alone. He won't admit how nice he sleeps when he sees you in his dreams. You motivate him to get out of bed easier on days he gets to see you so that's a plus

Papyrus: He likes to be around you as much as he can. Like doing menial things together?? Oh you have a doctor's appointment, sure why don't I come and we get lunch afterwards. He just likes spending time with you! "Accidentally" making too much food for meals so he has a reason to see you and make sure you're eating something.

Underfell:

Red: Heavy denial before reluctantly accepting. He's a flirty guy he thinks it's all fun and games until he's thinking about you at 3 am with a blush in his face imagining a future and doing cute relationship things with you. He knows he's fucked. He doesn't really believe someone would like him so from his perspective it's one sided attraction all the way and that hurts. He still flirts but it kinda hurts him inside too. Teasing himself with something he thinks he'll never have. He doesn't distance himself but he's a bit rougher maybe trying to scare you off a tad.

Edge: Denial worse than his brother. He doesn't have time for crushes or anything of the sort. It's improbable that he does like you that way anyways it's just a passing attraction he simply likes the way you say his name, and the way your legs look when you walk and stretch out, and oh … He's fucked. He'll continue to deny it to himself until someone ,most likely his brother or his version of Undyne, points it out. Then he's trying to hide it, trying to play it off. The passing touches he lets linger too long, how even though his days are scheduled he still somehow ends up running into you occasionally.

Underswap:

Stretch:We got another daydreamer and he's 50/50 with risque and wholesome daydreams. He finds any excuse to touch you and let's the touches linger. He's flirty and loves if you flirt back, kind of easy to fluster flushing a gorgeous marigold shade as he nye he he's. He invites you over for gaming or movie nights, wanting to share his interests with you and find some shared interests in shows and such. He definitely has written a song about you that he keeps hidden in a folder in his closet. There's a doodle of you on the back of the page and he's a little embarrassed of it.

Blue: He can tell when he likes someone like that he's pretty intune with his emotions. He likes to hang around you taking time out of his day and dedicating it specifically to you. He writes you little notes and reminders and hides them around your space to find, knows where you hide when you're sad and hides a bunch there. He blogs about you on occasion never mentioning your name but simply writing about you. He likes to find two player games for you two to play together mainly team working puzzle ones.

woopsies

cut my hand pretty bad and my roommate thinks I need stitches lol she's driving me to da hospital and I'm so woozy from blood loss so that's fun what a way to spend a Friday night

On an average day what's in those pockets? UT,UF,US

This one was interesting Edge was the one I struggled the most with but I'm pretty satisfied with it! Enjoy!

Undertale:

Sans: Ketchup packets, a miniature joke book, whoopie cushion, old trash he keeps forgetting to throw away

The ketchup is pretty self explanatory he keeps them as a little snack when he doesn't have access to a full bottle. The joke book he's read a hundred times but he keeps it more out of sentimentality at this point. He and this whoopie cushion have history besides Tori it's basically his best friend at this point. He doesn't like to litter so when he has trash and there isn't a trashcan near by he sticks it in his pockets and he just keeps forgetting to throw it away. Papyrus normally has to clean to trash out on laundry days.

Papyrus: bandaids, monster candy, his wallet, his schedule

Paps is pretty on top of everything and I have a hc that when he goes out with friends he's the mom friend that has a fanny pack with anything practical you need. On regular days he carries bandaids for his human friends and monster candy for both human and monster friends. His wallet is self explanatory he likes to have it on him in case he sees something he'd like for him or his brother while out and about during his day. He also has a bunch of photos in his wallet he likes to look at and show off to people they're of him and his brother, some of him and frisk, him and Undyne. There's even one of him and the queen, he's very proud of that one. I believe Papyrus is a very scheduled person as he likes to fit as much as possible into one day. So he carries around a schedule that has what he's up to that day written out. It has a little pocket with stickers in it that he uses to decorate the schedule and mark what's completed with little stars and emoji faces to mark how he felt about the excursion.

Underfell:

Red: hand buzzer, headphones, snack sized chocolate bars

He likes to trick people with the hand buzzer and thinks it's even more hilarious when he can get people he's gotten before with it. Red actually likes to read but he needs glasses which he is extremely embarrassed about so he refuses to really read in public unless he absolutely has to and then he struggles through. The headphones are to listen to audiobooks when he has free time. Reds a muncher and he loves chocolate so his jacket pockets are stuffed with snack sized chocolate bars, if he likes you enough he might share.

Edge: his cell phone, his reading glasses and washi tape, peppermints or something minty, a pocket knife

Edge is another scheduled person except he keeps his reminders and to do list on his phone. Edge also has poor eyesight but he doesn't care if people see him in his glasses. If he needs to read he puts them on and he thinks he looks extremely attractive in them. Mints help with improved focus and he likes to let them sit on his tongue as he goes about his day. He keeps the pocket knife for protection sure he he also like to whittle at sticks he finds and carve little designs into them to pass the time. He formed this habit when he was younger and used it alot in his traps when making spike pits underground and now just does it on a smaller level to pass the time.

Underswap:

Stretch: Lighter, a box of cigs, some form of hard candy normally lollipops,a notepad and a few pens, a dog treat or two/and edible or two

Lighter and cigs are self explanatory. The hard candy is for when he can't smoke or if he runs out of cigs and can't get some for awhile. I think he'd like to jot down notes throughout the day just stuff that catches his eye or song lyrics he thinks up. He's also a major doodler and half his notepad pages are little doodles of things he finds interesting there's a lot of his brother in there. I'm in between him smoking actual weed and smoking dog treats so I think he's half and half when carrying them around.

Blue: His cell phone, headphones, good luck charm, a special pen that has a little bone charm on it

I hc Blue as a streamer so his cell phone is important to him because he likes to update his fans and blogs throughout the day about what he's doing. He likes to have a soundtrack to his day so he wears headphones alot when he doesn't have to socialize with people (think grocery shopping or simply walking) it helps his mind stay focused and on track better. The good luck charm was a gift from his brother that he sort of started carrying around and never stopped. It's a small rock with a hole naturally worn all the way through he wears it around his neck as a necklace. Stretch found it one day when Blue forced him to go geocaching with him. The pen is in the rare case a fan spots Blue in public and wants an autograph. He likes having a special pen just for that and he carries it around because he's a hopeful person. It's only happened twice and he was so overjoyed he talked about it for weeks.

SO on period UT,UF,US,HT!

Ive had this sitting in my notes for awhile wasn't super proud of it still ain't but I wanted to post something, I just had to slap the HT brothers on and boom new post.

Also I've been wanting to write swapfell but I don't know the difference between that and fellswap or really their personalities cause it's so different for each fanfic so if someone could pls explain 🙏

Anyways here y'all go hope you enjoy!

Undertale:

Sans: I feel like sans is pretty knowledgeable so you didn't have to explain it to him. He takes it pretty maturely it's a natural part of life. The puns the horrible puns. He has so many specifically for this time of the month. He's always got your comfort snack on hand in his jacket pockets. He doesn't really change much he'll get off his ass if you ask him to but he sticks by your side mostly and lazes out cuddled with you while watching shows. Pretty good at getting products and snacks you might like he likes to get you some new snacks to try with him and he's good at guessing what you might like.

Papyrus: This man is prepared. After you tell him what it is he researches it and WOWIE he wishes he just asked you to explain but now he's over prepared with knowledge! He has hot water bottles and weighted blankets at the ready. Any snacks you want, heck you want a whole meal? He's on it and it's prepared with extra love. He carries around your products for you and always has pain medicine in his bags. Pretty good at picking them up from the store too and has no shame getting them.

Underfell:

Red: You gotta explain it to him and this man is bewildered for a bit. ya bleed from there for how long??? every month?! He's a little impressed?? Last he checked humans weren't supposed to lose huge amounts of blood but you're treating it like it's a normal thing. After he gets over his initial shock he'll try and help the best he can which is a little awkwardly. He makes a little nest for you out of blankets and pillows and makes sure you're comfortable. He and his magic run warm so he'll lay on your stomach and cuddle to help with cramps, pet his head and he might purr. He's pretty confused about products def one to send Babe what's your pussy size.

Edge: He's aware, he's done his research on his own when you were ovulating about the human "mating cycle". Not a fun experience but he takes it in stride. He listens to what you need and trys to deliver. Massages for sore muscles and heating pads for cramps. He'll make you comfort food while you relax watching a show and join you afterwards for some cuddles. He's pretty good at getting products for you and takes the ones you like into consideration but he's always looking for better healthier alternatives for you.

Underswap:

Stretch: Knows about it (blue taught him when he found out and Stretch showed interest in humans)and is a little awkward(traumatized from the talk with Blue). Hate to say it Stretch doesn't really know what to do he's not grossed out he just doesn't know how to handle it. He tries his best to be comforting giving snacks, heating pads, and cuddles. He's so awkward going to the store to get products plays it cool but has no idea what he's doing and definitely gets the wrong thing after his mind blanks while staring at all the products for too long. You just gotta train him he'll get better.

Blue: Also knows and he's handling it alot better. He takes it in stride and understands the biggest part is you're uncomfortable and he's going to do his best to help with that. He takes care of chores you don't want to do, makes you comfort meals, and always has a heating pad ready. Has so many two player comfort games lined up for you guys, he has stuff to do but most of his work stuff can be done at home! Which means he'll just be a shout away if you need anything . Pretty good at getting products and is one to carry some around in his bag just in case when you guys go out.

HorrorTale:

Axe: You have to explain it to him… Multiple times. He's confused as to why you smell like blood, he likes the smell but he's confused for a bit until he writes a note about it. He will not remember which products to get unfortunately. He's so confused staring at them you'll have to instruct him very clearly over a call and he still probably grabs the wrong one. Cuddles are supreme he's a giant so he'll engulf you in his form and his purrs practically shake your whole body. It's like a free massage chair whenever you want. He sticks closer by your side during this time of month knowing blood means your wounded and his protective urges flare up.

Willow: You'll also have to explain it to him and he's extremely worried when he smells blood. Even more so when he learns how long you bleed, he knows how much blood a human can loose and it worries him you're losing so much. After you explain it's a normal thing and a part of life he calms down slightly. He cleans and cooks a lot when stressed or worried so you constantly have something to munch on and you don't have to worry about any chores. He stays over stocked up on supplies, he doesn't like going out in public very often but for this he will because he deems it important enough. It's why he stocks up so much when he goes out. Mother hens over you hard and you might have to pull him into cuddles to get him to relax for a bit.
