Grin

"Sans!"

a sudden pounding had errupted the sleep deprived skeleton as he shot up and rushed towards the door. "Finally!" Went Papyrus once Sans answered him, "I will be late today and can't afford to take you with me, but does not mean to slack off!" He gulped as the threating look of his Boss is giving him, "which means, to your post and back, if I find out you disobey me, there will serious conquences, You understand!"

"Y-Yes Boss" he went shivering as he gazed down at his Boss's feet who gave a small pat. A sudden flinch at the touch cause Papyrus to frown, but he said nothing. Once he was done, he turned a heel and quickly stomped off, leaving a fearful, shaken brother alone in his home. Sans grudgingly walked out not bothered to change since he always sleeps in the same clothes; and entered the streets of Snowdin. Since there were no Papyrus people now bravely gave Sans the necessities provided. Everyone slowly had changed since their move in the small town, honestly despite the rest of the underground. There was hardly an dusting involved here, the "kill or be killed" motto had changed. That was good.

"Hi!"

He paused as he looked around to see who was actually brave enough to talk to him. "Down here" he turned his red gaze down to see... a baby skeleton? They looked exactly like him, except for the button eye on the left, wearing blue, grey blue, and white. A scarf was tied around his neck and the kid held no sharp teeth. Innocence. Something rare to see down here. "You look like me! Only cooler!" Well that was unexpected, hardly anyone saw him cool, but that was because of his 1 hp and the fact no one knows of his abilities. "Heh, sweet kid, but I am anything, but cool" he said feeling his depression kicked in.

"But I think you are, Plus you have your eyes glowing red, I can never have them glow like that for long" he said as he continued to look up at Sans with kindness, innocence, and adoration. "Cute... what your name, kiddo?"

"Button's!" He said proudly.

'No sure if that pun was intended, but oh well' "Heh, I can see why, you kinda cute as a button kiddo" it grew silent for a while causing the air to tense. For a moment Sans begun silently panic before hearing a erupting laughter bubbled the air.

"Nice one Mister! That really tickled my funny bone!" Now it was his turn to laugh. Feeling such a sudden relief as the child beside him joined. It was such a lighthearted scene, no one dare interrupt the sudden bond. "Button's" Sans turned to see who had called the child, only to be greeted with the same women, Papyrus loathed, "Mommy!"

'Ack- "MOMMY"!?!? SHE'S HIS MOTHER!? WHEN-HOW-WHAT-' dear Asgore he was gonna faint. "Oh hi suga, I see you meant my adopted son." "Oh, oh" well that's nice to know. Picking up Button's she approached Sans with a sweet loving smile, "want me to walk you, hon?" She asked causing him to turn several shades of red before giving a slight nod. She gave a small giggle as she let Button's down, "go on ahead, but not too far" giving a nod Button ran forward.

"Sweet kid, but how-"

"I made a challenge for Alphy and she manage to find him. All honestly, he was meant to actually be a "child", but turned to an "Adopted Child", he's improving though" she said. She could feel the ache in her abdomen had been building up, she gonna start whinning soon if she didn't take care of it. Giving a shaky painful breath she walked on with Sans beside her, and Button's up front. Sans had taken notice of her pain, and was curious of why she was hurt, but he was afraid to step over his boundry.

"So where's that prick of a brother of yours hon?" she asked showing such distaste for the tall skeleton. "H-He at work," he answered as he felt her lean near him, "thats good, cause I kinda got a proposal for you" she purred causing him to flinch as she nuzzled the side of his cheekbone affectionately. They had be walking a while before realizing they were there. "Wha-What proposal Mama?" He looked up to her with cautious eyes and slight color of red on his face.

The coil in her abdomen tighten, 'fuck! Don't pounce him! Don't pounce him! Don't pounce him! Don't pounce him!'
"Well, for a while now I've been noticing alot of complaints from the residents here, about Papyrus. Now I offically don't like the bastard, sorry to say, but it concerns you as well hon" she went frowning as he jolted back from her.

"Ahem. Well, considering how my people are being dusted for no reason hurts me, and it really hurts know your getting injured, whether mentally, emotionally, or physically. It is consider abuse, which ironically I do not tolerate, so my proposal is..." he slide glanced her as she looked a bit nervous, "I fight Papyrus over custody for you."

"Wait what?!"

She chuckled at his shock, "no clue about dynamics do you baby bones?" He shook his head rapidly as she gave a gentle kiss to the top of his nasal cavity. "Well dynamics involve those in this system tree, Alpha(me) is a leader and a powerful one at that, my duty is to keep tabs and be protective to my people. Betas are knights and hunters to the pack usually in this case dogmay and his mate are under that list since they do work for me as well as betaAlphas such as Greater dog, and Doggo.
Your brother also fits in that catorgy, however he has been threating my position as Alpha which I am going to fix sooner than later." Button climbed onto the counter top of the sentry post.

"Finally Omegas, now they are know to actually be submissive and motherly to children or pups of the pack, weaker yes, but highly valued since they really great lovers as well as perfect protectors to young."

'Seems more like me, well beside the mothery stuff' he thought blushing. "So what does it have to do with me, Mama?" Another coil in her abdomen, "well sweetie, for starters I do want you," a blush was now on her face, "I hate how you're scared and being tormented by your brother. I will not hurt him if you think I will, maybe rough him up a bit. However when an Alpha and a BetaAlpha fight it means claiming territory or for mates in this case its... well... mate"

Sans was now red as a cherry, "m-me!? Why me!? I'm just a 1 hp monster, I am nothing special!" "Don't lie to me suga" her voice was now devoided and cold. "I know about the resets" he flinched, "Frisk comes here alot, and I know damn well how they are, if anything why do you think Snowdin is always immediately evacuated?" Well that shed some light in this, before long resets usually always started in Snowdin as usual, but this one started in the captial. His brother was waaay worst than anything in this timeline, but then again it could be a glitch so-

"Sans"

"Huh!? S-Sorry Mama" he went as he looked at her. She looked so concerned and sad, it send threads of ache in his bones as he looked at her. "It's okay, as I was trying to say, you come with me here and now, I'll be sure you're protected and safe, as well as keeping an eye on your brother."

"And... be your" he gulps, "mate?"

(Y/N) smiled while stroking her fingera against his cheekbone, wiping the tears that had form, placing a gentle kiss on his forehead. "Only when your ready, in all honesty its been hard to holding back, but I'm willing to wait if it means for you to get comfortable."

"Mommy, look I found two snowflakes, they're so big!" Little Button had two snowflakes as the size of his palms. "Why are they different?" Sans chuckled nervously as he gazed at the innocent doppleganger, "just shows that every snowflake is special kiddo, if they were the same it would be boring you snow" Button laughed as (Y/N) snickered.

"Dear lord, that was terrible!"

"You're smiling"

"I know!" She laughed, "and I hate it!" He found himself genuinely smiling at her as Button gently place the snowflakes down and rocked his legs over the edge. "Daddy, up please~" Sans froze looking at the smiling child before picking him up, a sudden warmth came in his soul as he held the fragile child. (Y/N) smiled at him l which encouraged him to relax and rock Buttons to sleep.

"Okay"

"Hm?"

"I'll go with you" he went smiling almost nervously.

(Y/N) literally felt her heart leap, is it her soul? Yup defiantly soul, she was really happy. Never has she felt happy like now, maybe sexually happy, but never happy-happy. 'Whoa calm yourself! Just chalk it up as "you're happy" don't make a big deal out of it' she scolds herself before smiling down at her babybones. Hugging his shoulders with a content sigh as she nuzzled closer to him. Sans was leaning into her with a content smile, for once he actually felt safe, he felt loved, and he actually felt accepted.

"Should we get your stuff, hon?" went (Y/N) before seeing him nod, "I really don't have much Mama" understanding she smiled as she then pulled off. "Come on, I'll have Annoying Dog cover your shift, since he's the only bastard to fuck'in tolerate and survive your brother's attacks."

Sans snort at this knowing so many times that dog had come after Papyrus's bones, all in fun and to piss him off. "Alright" he said as she walked in the direction towards Snowdin. Sans sat back down in his sation while he waited, little Button was curled in his arms sleeping away, 'how small you are' he thought wiping away the drool that had form from his skeleton-mouth. Small little hands held onto his shirt as he, buried into Sans's shirt as he rubbed against his chest. Finding himself smiling down at ease. 

***************

(Y/N) smiled at Annoying Dog who huffed and glared at her before nodding, luckly it wanted to piss off Papyrus today so he dashed off quickly towards the direction where Sans and Buttons were at. 'I can't believe it just went so smoothly, but knowing his brother, this might all bring unwanted threats and dangers for her babybones. She couldn't do that to them, it wouldn't be right!' She thought as she begun making her way back, "You're gonna get youself killed you know" said Dogaressa as she looked almost sadly at the human woman, "Like he could put hands on me, and even if he did I'll come back full time, with full force... I won't kill him, but I will make sure he would never, and I mean NEVER lay hands on Sans ever again" she went feeling her soul pound against her chest with full determination and sudden bloodlust that it shined right through her physical form. 

Dogaressa smirked a bit before turning, "be sure to save some bones for me and Dogmary" 

"will do" she went as she begun her way towards the person she knew who would need her in their life, both of them do.

 

********************

Sans wasn't at home when Papyrus got back, which pissed him off because that would mean that his brother could be at Grillby's which was against his laws of the house. Stomping towards the wrecking place he broke the door once more of the bar which caused an outburst from Grillby. When Papyrus had asked where his brother was, Grillby shook his head, "Sans hardly comes here because of you, matter of fact he never comes here anymore, so why would he be here if you keep beating the shit out of him!?" Papyrus glared at the bartender glaring at anyone who looked at him, causng him to ask many people where his brother was and who might have him. 

"Yo Grill, why is the Flamboyant bastard here?" asked (Y/N) causing the tall skeleton to growl in distaste for the woman, who looked oddly calm and collect, "Sans isn't home where he should be, YOU wouldn't happen to know where he is now right?" went Papyrus. Dear Asgore he hoped he wasn't with her, he better not be with her. He perfer he was with Greater dog, or with Grillby than be with her. 

 

Despite him wanting to murder anyone who would look at HIS Sans, let alone touch him. 

 

(Y/N) smiled at him which caused a sudden drop in his nonexisting stomach, "well where ever he is, he's probably in a better place then be under your care, I mean honestly what kind of brother isolates him from people, or beat him, or probably starve him, and... You know I could go on with your list of abusement, but I have no time, I have a baby at home that needs to be fed and taken care of." she went as she passed the tall skeleton and picked up whatever she bought and quietly walked towards the door.

"Oh and if you do find Sans, tell him Mama loves him" she went with a shit-eating grin and walked away.

"That Bitch"
