Underfell! Sans x Reader [Short Oneshot]

a broken soul

[trigger warning: physical abuse, cussing, insults, childhood trauma]

Third POV

"You fucking lazy bitch," Sans spat at you. You flinched, looking at him with pure horror and grimace. He laughed, "Quit looking at me like that, you know that I find that so irresistable," he then chugged his bottle of alcohol. You gulped, looking away. You furrowed your brows, thinking what just has happened. You gently touched your cheek and winced. Bruised, again.

"Irresistable to punch, that is." He let out a loud laugh, walking away from you. "I'm just gonna go back to Grillby's." He murmured, swaggering his way out of the house.

You were constantly getting physically abused and hit by Sans. You never said anything about it, knowing that you'd only get blamed for what he's doing. Since he met you, he has been like this. He said it was to keep himself happy, because seeing others suffer is his source of happiness. You thought it made no sense, but again, this is the Fell AU. It's completely different from the Classic AU.

You felt revictimized, since you had history of abuse from your parents. You've grown in a household where you were always getting criticized, neglected and harassed. No one even tried to listen to your plea.

When you turned 13, your parents brought you to a psychiatrist, only to get diagnosed with depression and BPD. They didn't believed it, despite the fact that a professional had said it. They even blamed you for having all of those mental illnesses. They went back to constantly hurting you, mentally, physically and emotionally.

Your father was a narcissist, he never cared. Your mother was hardcore alcoholic. There was no use to even trying to talk to any of them when all they do was abuse you and be their "scapegoat".

It was really difficult and such a rough patch to heal yourself and to cut ties from them. But hey, at least you made it here, you're still alive and kicking. Keep yourself alive.

This exact thing that Sans was doing to you made it hard for you to pick yourself up again. It was really devestating. You blamed yourself for everything that has been happening to you, on how you got there in the first place, and everything else.

You wished you could escape from this hell, but there's no way someone is going to help you when everyone else is ten times worse than Sans himself. You just swallowed all your fears and let him hurt you until you were almost to passing out. There were some rare times Sans would treat you nice, only if he hasn't been drinking and taking drugs so much. It was the deal that made you stay.

You love him, you really do, and you have to let him do what he wants with you because you think that's "love". In fact, it isn't. If you love someone, you won't be scared to ask for help. If they love you, they will tell you everything and they will try everything ust to make you better. Sans was basically just not like that. He was toxic, manipulative and overall abusive. You wanted him to change, but he never listened.

One day, Sans came home. Surprisingly, he was... not drunk nor high. That's a little sus. He wasn't even noticing you at all. He seemed a little distant and timid. You thought to yourself, 'What could he be hiding?' Well, you'd never know. We'd see, amirite?
