Chapter Text
The atmosphere is thick and dark, bringing everyone in the group into a slight depression. You notice a sheen of liquid glossing over Lanas eyes, clearly trying her best to keep from weeping under the pressure that Charas soul is putting on your own souls. Luna has taken to scowling and using one hand to grip the opposite arm tight enough to discolor the skin.
Frisk’s usual nonstop cheery demeaner is replaced by a teen who can do nothing but look at the ground as they walk, their shoulders drooping lower than you’ve ever seen. You yourself can’t bring your hand off of your swollen tummy. Your head lulling to either side, eyes moving over every shadow and empty corridor your group passes. Your maternal instincts slowly turning feral as you worry for the two beings growing inside of you.
None of you speak as you make your way out of the true lab and deeper into Hotland until reaching the capital. Luna was back to carrying you on her back, your now larger bump making it a little more uncomfortable. You could also feel a slight movement from your backpack as you assume Charas soul bumps into the glass walls of their new temporary home, surely excited and scared of the new development.
Normally, your group would do a little sightseeing instead of the brisk walk you were at now. But the longer you’re underground, with the tattered soul belonging to the ginger haired ghost, the more on edge you become. Luna is basically paranoid at this point, her hands periodically tightening around your thighs and her head twisting at the slightest sound. You didn’t know if it was because of how eerie it felt to be in a completely deserted ghost town, or knowing that at any second with the magical forcefield being gone, the cave could potentially fall in on itself and trap the four- er, five of you down here for the rest of time.
Are the excuses you’re making. Not willing to admit that the lone soul is draining every piece of warmth from the group. Hungry to become full once more.
Even Frisk, the human child that freed the monsters and spent so many timelines down here, was flinching at the moving shadows . You can’t help but hope that memories of darker timelines are filling their tiny head. That would be far more relaxing than the feeling you’re all feeling at the moment.
“...Should I just call Sans?” You finally break the silence, your words coming out slow and slurred due to your jaw feeling unnaturally heavy.
The group stops in their tracks, eyes either squinting or widening. Disbelief apparent on all faces. How had no one thought to reach him? It never crossed your mind until now to get the one person you know can teleport you all out of the growing pit you’ve sunken into.
You almost want to hit yourself for being so stupid until now. With three nods, you dig around your sweatpants pocket until you fish out your now cracked phone. Huh, when did that happen? Your fingers dance along the lifted screen, your muscles typing out your boyfriends' number.
The phone hasn’t even reached your ear when he answers in a gravel voice. Must’ve woken him up, you aren’t quite sure of the time. “babe?”
You stay silent for a worrying amount of time; you can hear him calling out to you but for some reason you can’t respond. Your grip loosens on the phone, it eventually falling out of your grasp and hitting the ground, smashing it even more. You doubt you’ll be able to turn it back on.
Your vision begins to warp and blur, your head feeling heavier and heavier as the seconds tick by. Looking past Luna for an answer, you notice Lana has face planted onto the scalding floor. Beside her, Frisk is leaning against the rock wall, their head hanging low. You can’t react. You feel Lunas grip loosen on you as she falls to her knees. You don’t know what happens next, instead your eyes close and you’re surrounded by darkness.
The last thing you remember is skin scraping against rock.
~Sans POV~
He spent the passing days worrying about you, obviously, but also trying his best to figure out how to control his feral outbursts. Gaster had run a few tests that proved both Skeleton siblings have grown more in their monster DNA. Slowly they were developing much like a pre- pubesant monster would when starting puberty.
When a monster starts to develop sexually, they tend to become more possessive over their belongings or the ones they share feelings for. But it usually only lasts a week or so before they learn to control their basic urges.
Sans had experienced a few more moments since the incident, but luckily he was either by himself or managed to keep to himself and walk away when they tried to take over. He really doesn’t want to hurt you again. Especially now that you’re carrying his child.
He knows that being locked up in the lab all day every day has started to get to you, you were clear in letting him know you were lonely and wished he’d at least sleep next to you at night. But, until he gets everything one hundred percent under control he can’t trust himself to be around you at your most vulnerable .
Granted, you were very proficient at talking him into at least having sex with you. And there were days where Papyrus was able to pull him away from his desk for long enough for the four of you to have a family dinner together. It’s those moments he loves the most. It was the closest to normalcy your small family had gotten to in a long time.
Sans had fallen asleep in the lab for the fifth time that week, a row of test tubes lay next to him along with research papers. He was actually working on a project for college for the first time ever. Figuring the distraction would do well in keeping from him popping up Underground and stealing you. He didn’t tell you the first day you went, but he loathed the fact that you decided to travel down there without him, just to get that rotten, undeserving childs soul.
But you didn’t need to know that. He didn’t need you to jump him over something so trivial anyway. It was bad enough that you nagged him every day to get out of the house. But he has to say. He really misses your constant badgering.
He doesn’t dream, just allows the dark behind his eyes calm him for a night.
Or so he thought.
Apparently, he never turned his ringer off before crashing. The loud obnoxious ringtone you had set for yourself on his phone blares in his ear holes, forcing him out of his seat and onto the floor in utter tired shock.
The room fills with some weird dubstep beat slowly getting more and more intense until he realizes it’s you and quickly answers, filling the room with silence once more.
“babe?”
