A bit of a niche request but may I get a order of Geno Sans? His story and comic was interesting to me and when it was completed is one of my highlights in my time in this fandom.
⚠️Warning for a bit of gore~
I swear I’m still on the hiatus until Monday for this huge commission I am just now halfway done with, but… I got angsty for a second~

@cherry-blossom-consumer @lynx-the-cat
Thank you @robobbin for this adorable commission of Mafiafell Sans caring for their OC sick at home. You know I can't live without big scaryboys absolutely melting when their darling is unwell <3
---
“hey sweetcheeks.”
You looked up from your position nestled on the couch, a flash of hot confusion and embarrassment momentarily awakening you from your feverish stupor. That... wasn’t the voice you expected to hear, coming through your front door. You lifted your head up a few inches- movement in inches was all you could manage right now.
... It was Sans. Sans was in your house. He had a nice, pressed red shirt and black pants- your spare keys hooked onto a claw, two plastic bags over one of his big arms, and an unreadable lilt to his shark grin.
“... Sans?” You mumbled, eyes widening into saucers. You felt your cheeks immediately get even hotter.
Your fever hadn’t improved, as you’d hoped it would. In fact, it had only gotten worse as the hours wore on; moving and thinking had grown increasingly impossible. In a total mess, you’d called Papyrus, asking if he could bring over something for you to eat... though you didn’t actually recall what he’d said back to you, most of it just blurring together in your head.
... You’d been expecting Pap. Pap knew you, he'd already seen you weak and gross before. Pap had carried you home from the gym, once, after you made the mistake of trying to keep up with his workout.
You were not anticipating the arrival of his hot brother, whom you had a massive crush on.
Despite feverishly sweating, you pulled the blanket further up over you. You felt embarrassed to be seen like this.
“sorry, i know you were expectin’ boss.” He put both of the plastic bags down onto the coffee table, crouching beside the couch to be closer to your eye level. You twisted your hands in the blanket, his proximity making your heart thump. “he’s swamped with work, so i’m droppin off the emergency goods instead. though i’ll be sure to let him know you missed him.”
“... O-oh.” Your mind was fried. You stared- he looked great. It felt like the longer you knew each other, the better he dressed, it was amazing how his presence could simultaneously make you feel so much worse but also so much better. “N-no, it’s okay. I’m... fine. You’re fine.”
He chuckled, musically, eyelights warm. His voice felt good in your painful chest. “i’m fine?”
“N-not like... fine as in hot. Fine as in okay.” Your cheeks were just on fire at this point. The fever had removed any and all barriers between your head and your mouth, so words just waterfalled out. “Not that you’re not hot. You are. You’re very hot. You.. uh,”
... Shit. Again, that little edge to his smile. You wanted to sink between the couch cushions and die.
Rather than make fun of you, Sans just gently reached over you, placing a cold compress against your forehead. He was so close you could smell him.
“you’re burning up. and ya look terrible. i’m gonna stay over and watch you.”
"N-no-!!" You blurted, nearly sitting up. The guy you liked, staying and seeing you completely out of it, at your absolute worst? No???
He grinned. "sorry, pet. not gettin' rid of me until your fever goes down."
... You covered your face with both hands. This was mortifying. Were you glad he was here? Absolutely. You didn't want to be alone right now, and his insistence on staying despite your protests felt good. But you still wanted to die.
“pap really went nuts with the food when he found out you were unwell. y’know he’s got a list of all your allergies? let’s see...” You could hear him start unpacking the bags, placing things onto the table. “some funky soup. saltines, popsicles, iced coconut water. ginger candy... whole bunch of herbal teabags. you ever had sea tea?”
You kept one hand on your face, gesturing randomly with the other. “Soup. Soup please.”
“soup comin’ right up, gorgeous.”
You tried to say thank you, but just a weak grumble came out, the room was spinning again. You heard him move into the kitchen... so you just let yourself sink back into the couch, comforted by another person’s presence.
...
You didn’t know how much time passed, he eventually returned. You could smell something nice.
"hey. can ya sit up a lil, for me?'
... You didn’t really respond to his query. Curled in blankets like a feverish squirrel, you merely made a sound in the back of your throat to acknowledge him. The fever was getting worse.
... Big hands, on your body. There was movement... Sans shifted you, everything spun. You were vaguely aware of him sitting you up, supporting you with one big hand- you did your best to just watch his face, focus on his lovely red eyelights.
"c'mon. soup’s ready. here comes the airplane."
... Despite the state of you, that made you giggle. And judging by the smile that filled your wobbling vision... he liked the sound.
///---///
...
... He was probably enjoying himself a little too much.
Sans shifted his legs into a slightly comfier position from his spot in front of the couch. This definitely wasn’t what he thought he’d be doing today. He’d been planning on going out for a drink, maybe crossing some names off a list while his blood was up- the usual stupidity he filled his free time with.
... Then he got Pap’s call about you. And instantly, it had felt like nothing else in the world mattered.
Now, here he was; in his crush’s house, spoon-feeding her warm soup, trying to keep a nonchalant face while wrestling with an (emotional) noisy Soul.
... i haven’t felt like this in a long time.
You were so cute. His nasal ride wrinkled, and he pinched the soup spoon a bit tighter, restraining the urge to grab your cheek- he felt bad for not being able to stop thinking about how cute you looked, when you were so unwell. But he couldn’t help it. All snuggled up in blankets, hair frizzy and unkempt, glasses askew, flushed and warm... you had a twinkly, glazed look to your eyes, not too dissimilar from the look people got when they were drunk. He’d been fighting the urge to ruffle your hair this whole time.
...
Sans bit his tongue. This was mundane, compared to his normal life. Some might even consider it a chore. But... he hadn’t felt this nice in so long. He felt... useful. Wanted.
When was the last time someone had been openly, willingly, weak around him? When was the last time someone was in a state of fragility, and wanted him nearby?
Mushy feelings filled his chest. Soft. Overprotective. He was hyper-aware of how sick you were and he didn’t want to leave your side, not even for a second, not even to go home. Even just acknowledging those emotions made colour rise to his cheekbones... he hadn't felt anything like this level of protectiveness since Pap was just a babybones.
... But damn... it felt good to be needed.
...
Warm fingers curled around his hand.
He very nearly jumped out of his fucking seat at the sensation- he fumbled the soup spoon, mumbling out a little ‘shit’ as he broke out of his thoughts, turning to look at you.
... Your tiny hand was wrapped around two of his phalanges. Sparkly eyes peered up at him.
fuck. His Soul thudded in his throat. don’t look away from me.
"... h-hey. c'mon." His voice was shaky. "that ain't fair."
"Huh?" Came your bleary reply. so fucking cute. stop it.
"you've stolen my hand, doll."
... You looked to his captured hand, slowly. Like you only just realised you had it.
...
"... Mine now." You mumbled.
...
He tried to muster up a quick joke, like always. Tried to come up with a sharp-witted response. Something with swagger, something with a flirtatious edge, something with confidence that would show you how cool and collected he was.
...
Nothing came out of his mouth. It was like trying to start an empty car.
“... o-oh.”
...
"... You're great." You said, eyes fluttering closed.
"... huh?"
"Great guy. Handsome guy. Nice to me." It didn't sound like you intended those thoughts to be said out loud. He felt his eyelights flare- his Soul was thumping against his ribs.
Words banged at his tongue, but the only sound he managed to get out was a tiny shaking hum of affirmation.
You drew his hand up toward your face, he absolutely had the strength to stop you but he felt like he’d been flashbanged. All he could do was watch... as turned on your side to get cosy, pulled up his hand to your face... and happily nuzzled the back of it.
“My big guy.” You murmured.
...
Just like that, you were asleep.
...
Sans used his free hand to cover his face. His whole skull was carmine red, glowing like a campfire. It made him look almost as feverish as you.
...
i never want to leave.

Howdy!! This is the first time I've requested something from anyone, so please please please tell me if I'm doing something wrong/ have improper Tumblr etiquette, etc..
I was wondering if you could do headcanons for undertale sans and horrortale sans (maybe error if you feel like it) Or just one of the above if it's too much- with a reader who thinks they could definitely take them in a fight. (Spoiler alert: they can't.) Like.. Chihuahua energy/ all bark unable to bite?
Sorry if that doesn't make sense loll!!
Thank you. 🤠
This is so cute actually, unfortunately I don't write Error (love the guy but he's not one of my boys....not yet anyway), gender neutral pronouns
"Fight me coward!" Ft Classic & Horror
Classic Sans:
Agrees with you
He's a lazy bones with 1 HP, what he gonna do to you in a fair fight?
Content to let you bark all you want, with a teasing but loving "yes dear whatever you say-"
He's just a chill guy like that regardless of how efficient you are at fighting, eeyup his partner can kick his ass no problem. He has no trouble admitting that even if it's not true in this case
Especially when he knows you're not actually gonna try to fight him
If you do get bold enough to actually try though you're getting pinned his blue attacks in minutes flat
Y/N : "You said you'd lose in a fair fight!"
Sans : "heh....yeah a fair fight"
He pullin' out all the cheap shots, what else would you expect
Horror Sans:
You sure about that?
I don't write Horror as being a massive gigant unlike some others but he's taller than most Sans and does have more physical strength than magical abilities
This is basically a chihuahua barking at German Sheppard
Just kinda places a hand on your forehead like "cease" whenever you get on one of your tangents
If that doesn't shut up up he's just gonna lift you up
You're in air jail
And nope you're not coming down until you calm down
Won't actually fight you unlike Classic but not above pinning you down instantly to shut you up and gets a kick out of your surprised expression everytime

Sanguinary??? 😏😏😏 Wanna give us any peaks at hot, boney, blood sucking, seductive, and most importantly ... sexy vamipres?
boy do i

i've already spoken about this project here and released a 1,300+ word preview here, but i'll share another little piece since i'm so obsessed with it uwu
vampire-related shenanigans below the cut. reader definitely is not a willing blood-donor, so. warning for legitimate fear and associated pred/prey themes 🔞
“Rude little thing. I expected better manners from the one I have heard so much about.”
There are multiple sets of eyes on you. The windows above seem full of shadowy figures… like the whole party has come to watch your demise.
You take a step back and the skeleton matches it, his cyan eye dancing with eager mirth. Your fists clench in the fabric of your skirt, bunching it at your hips and lifting the hem off the ground. Your eyes dart to the left, where the other skeleton guards the door leading back inside. He watches the scene unfold with an eagerness that raises your hackles. No chance if you try that way. In desperation, your gaze shoots to the treeline. He seems to know your intention even before you do.
“Are you sure that's wise, my dear? You have but one path to take, and there are many things to fear in those woods. Beasts that only prowl at night.”
The unspoken threat has the hair on your arms standing on-end. The air feels tense, heavy with power as if something was preparing to pounce. You know you’re now standing at the precipice of an irreversible decision. Through the adrenaline and fear flooding your veins, there's one thing you know for sure. You're not just going to lie down and die. You're going to do everything you can to survive. You will persevere.
You turn and dash through the threshold of the trees, disappearing into the thick, silvery fog.
Behind you rings an echo of delighted laughter.
“So be it!”

I like to imagine the only time Sans has ever worn a suit was when Mettaton and Papyrus had a kid because he wanted to make a “good impression” on the baby

⋆⁺₊⋆ ━━━━⊱༒︎ • ༒︎⊰━━━━ ⋆⁺₊⋆
i like to think dream!sans is a reverent worshipper in bed.
it's like he's weaving poetry with his praises for you, the words spilling effortlessly from his mouth like molten honey. sickeningly sweet and laced with all the affection a guardian could hold for his significant other. he treats you as if you are the most precious thing in the multiverse and to him, you are. every kiss he graces upon your skin is quickly and reverently thanked before he places them. you can feel the warmth radiating off of each one.
"you're so beautiful.." a kiss on your wrist. "thank you.. oh, thank you.." a kiss on your shoulder.
"absolutely stunning.." a feathery soft kiss on your neck.
dream could easily praise you all day long. to him, every breath and loving syllable is worthy of your description. he is at your beck and call, more than happy to fall to his knees if it means he can hear his name and those pretty sounds fall from your lips in a breathless mantra. he may be an ancient deity, but dream will worship you like a devout follower if it means you'll grace him with your presence.
when it comes to receiving that same treatment, however...
he can't handle it in the slightest.
dream is more than capable of dishing it out, but unfortunately he is completely unable of taking it. he feels almost unworthy of your praises because he does not believe in them for himself. you are the only one who is able to see past his perfect facade. that is what he adores about you the most. you do not idolize him as this perfect guardian who can do no wrong. you know he is not perfect. in fact, he believes himself to be the furthest thing from it. but it is a standard he keeps trying to uphold because he feels he must. because it is what others expect of him. but you are there to remind him that he doesn't need to be perfect with you. that he can forgo the mask of that polite smile he wears and really, truly feel with you. he can be angry and scream, wail and cry if he needs.
and you will love him all the more for it.
those eyelights of his are wavering and unfocused in their sockets, shaky breaths rattling his ribcage as he watches you delicately kiss down his sternum. you can feel the soft tingle of his magic coursing just beneath the surface of his bones. it's a peculiar feeling, yet one that you keep chasing as you flatten your tongue to give him a lick. it elicits such a pretty sound from him, one so delicate and airy. a darling dust of golden magic colors his cheekbones. "so pretty.." you murmur as you look up at him with an adoring grin.
"ah!" dream's phalanges tremble as he quickly clamps both of them over his face. whether it was to hide his expression or muffle his sounds, you couldn't tell. maybe it was both.
"d- don't say such things when you're.. in a position like that..." you merely coo in response as you shift your weight on top of him, gently prying his wrists away from his skull. you press a kiss to the left knuckles, and then to the right. the gesture quickly earns you a flustered whine in response. "but it's the truth, sunshine. i think you're pretty. and lovely. and wonderful.."
your lips find their way to his collar bones, feathery soft in their ministrations as you whisper praises against him. when your teeth gently nibble one, his entire body jolts as a whimper tumbles from his mouth, but he makes no effort to stop you. instead, he surrenders himself to your ministrations, ultimately powerless. "so kind, and hard-working.." another kiss on his sensitive neck.
"strong... reliable." a kiss to the top of his skull. "my radiant light.." and another to his cranium. you can hear the soft, almost melodic rattle of his bones as they tremble under your touch. his fingers tighten their hold on you while your hand trails down his ribs, feeling the dip and curve of each one.
"y-you're too-- oh! you're too good for me, my darling.." you merely give him a loving smile. "it's what you deserve, dream. you deserve everything good, even if you think otherwise. but i'm going to convince you that you do, one way or another." there's a set determination in your voice that sends dream's SOUL aflutter as he watches you journey lower and lower down his body. he feels himself grow almost dizzy as he watches you settle between his femurs. you hold his aurum gaze the entire time as you press a slow, languid kiss right on his sacrum. that sweet little gesture earns you your name breathed on a moan from his lips.
stars above, you're going to put him into an early grave.
"will you let me show you, sunshine?" you gently coax him.
always so considerate. despite the lust-ridden haze in your eyes, you still look at him with all the adoration in the ever-expanding multiverse. even through his embarrassment at being reduced to a quivering mess over just a few words and kisses, the positivity guardian feels himself wanting to give his everything to you. who is he to deny you, the very one he loves? the only one who can make him feel this exposed. this.. open and tender. so, he implores you. "..please."
