Chapter Text
'We have some…unique guests, Sans. Could you and your brother possibly help them settle in?'
Toriel's gentle voice had held an odd note of hesitation but Sans had shaken it off. Monsters tended to run on the 'unique' side and many of them required help with adjusting to life on the Surface. Of course he had responded in the affirmative, Toriel was a dear friend and his little brother would be over the moon to help any and everyone.
An easy decision. Though Sans was often lazy, he was still an Omega and still had that innate instinct to take care of others. Not a shocking thing, seeing as he had happily raised Papyrus with no regrets.
Sure! The small skeleton had responded, whatever you need, Tori!
With the two monsters on his doorstep, he was also reminded, Omega or no, that the universe enjoyed fucking with him.
Two white pins of light, trailed up and up to take in these tall monsters. The first thing he had noticed had been that these two unexpected visitors were skeletons. He and Papyrus were certainly the only ones of that Type remaining, Sans had checked.
The second realization was that they were very tall, a trait usually possessed by Alphas. For a good moment, he was sure the smaller visitor was a Beta because his height was comfortably at a middle point. But a deeper inhale from Sans revealed that assumption false, both of their scents were unmistakably Alpha.
The third observation was one his Judgement ability made on instinct. These two skeletons had LOVE and they both looked battle hardened. Their bones had scars and their way of dress was geared to warn others away or be sorry.
The fourth point that came with the last as it revealed their names in their stats. Oh what the fuck, had someone found his machine? Had Alphys been messing with the Core?
And as he was keenly observing them, they were both doing it right back. Both seemed absolutely floored by Sans' very existence and it was laughable that he couldn't tell if that was because he was another 'Sans' or because he was the only Omega skeleton in existence.
Or he should still be. Damn it, the small monster would have to check his basement. This was surely a Situation.
"heya, i'm sans the skeleton. odd pickle we're in, seeing as you are also a sans and you are a papyrus. still, tori vouched for you so please, come in." He stood aside but they didn't come in, their focus now behind Sans and near the ceiling.
Ah. He didn't even need to look. Smiling, he motioned behind him and continued speaking,"this is my little brother, papyrus."
Sans watched with amused eye-lights as there was the usual ’sizing up' done between Alphas and held in his snort when both skeletons offered Papyrus that nod.
You know, that 'I recognize and brutishly respect an equal' that went on between Alphas. Welp, that was going to be an amusing thing to watch develop.
Seeing as Papyrus was extremely tall, most assumed he was an Alpha and Paps never corrected them. As soon as the monster had hit his growth spurt, it became a fun game. No, his sweet but mischievous sibling was a Beta through and through. It would take a quick scent testing to reveal that and they never did learn.
"Ah, yes! Please come inside, Queen Toriel told us to expect you! My name is Papyrus!"
After getting the 'okay' from 'The Alpha of the House', the strangers came inside as Sans hid his snort behind a cough. Secondary dynamics and the instincts could be hilarious fun.
"Yes, your Queen is too giving. We appreciate the welcome. I am called Edge and this is my older brother and mate, Red."
Sans exchanged a puzzled glance with his sibling. Mate? But they were brothers. Even more than that both monsters were Alphas.
"hey." Red's greeting was full of sharp teeth and his scent becoming heavier in wordless warning. Sans smiled back and held in his instincts to flinch, damn Alpha posturing.
"Oh! It is obvious you two are not from around here! What an odd custom!"
"don't usually see two alphas bonded." Sans cut in, making clear to Papyrus that they would not mention the incest. Uncommon with monsters but absolutely taboo with humans. Red's shoulders relaxed and Sans realized there must be some bitter feelings there. The other monster did have the opposite problem of his own sibling.
Not that they bothered to confirm that, heh.
Sans was used to being the shortest in the room, spare a few other monster genotypes. He came up to low spine on Papyrus and Edge, though Edge was a tiny bit shorter. On Red though, Sans came up to his chest.
Red was just barely shoulder height with his sibling…and mate. That would take some getting used to but the Omega wasn't disgusted by it. After all, it only became taboo with the humans when they figured out it was harming their offspring. Being made from magic nulled that issue.
Besides, his Omega didn't listen to social norms. It was purring over there being more skeletons. Wait, what?! Sans swallowed the physical purr that had been threatening to escape and stamped furiously on his Omega instincts.
Edge and Red were staring at him, making no attempts to hide that they were taking in his scent. He lifted a bony brow at them.
"rude. got something you wanna say?"
A good test. Omega were sometimes treated as lesser and Sans wanted to know exactly where these two stood seeing as they could be dangerous.
Shockingly, both Alphas had the decency to back down and apologize. A promising start considering Edge and Red looked like they were from a rough background.
"I apologize, Sans. It is a simple fact that we have not seen many Omega at all." Edge told him and Sans hummed in understanding.
"we've never seen a skeleton omega, neither." Red piped up and boy, did that brutally punch the elephant in the room. In fact, it was probably dead from being jacked right in the face.
Subtle as an Alpha in Rut.
"Fancy mentioning that!" Papyrus crowed, always the peacemaker,"Sans is the only skeleton Omega we know!"
"is he yers?"
Now the elephant's corpse had been desecrated and lit on fire. Stars! Did Red have any tact!? Papyrus only laughed it off, his awesome brother, as Sans' only reaction had been to lift his other bony brow in silent shock.
"No, Sans isn't attached to any Alpha! I do take care of him and look after him. I trust you'll treat him with the respect he deserves! He raised me and I am protective of him!"
Both Alphas straightened and did that 'nod of respect ' thing at Papyrus.
"Of course, Omega are to be treated gently. You have nothing to fear from us regarding him." Edge looked at Sans and he held his breath at the complex sharp gaze. That's odd, he could usually read expressions better. Sans looked at Red to find the same look.
Great. The other monster learned subtlety all of a sudden.
"Wonderful! I am guessing you both need a crash course on the Surface! Let's sit down and begin!"
