I'll be here for you ~ Sans x Reader

A frightening return

*Sans POV*
I thought that I might as well walk home so I didn't teleport back to the house. I was walking along the dark pavement when I suddenly thought I heard a scream! I stopped mid step and waited to see if I could hear it again. "Help! Please! Somebo- aaah" I felt my eye heat up, it was ((y/n))!
I teleported inside of ((y/n))'s house.

*Your POV*
((Rewind))
Dylan. Your ex boyfriend was standing clumsily on the stairs. He was drunk. He looks at you and smirks. "Hello gorgeous!" He says, slurred. You scream but he jumps down the steps and puts his hand on your mouth. "Hush, sweetie! You don't want things to hurt do you?" You elbow him in the stomach and yell "Help! Please! Somebo-" Before you could finish the word he grabs you and you scream. "You little bitch!" He pushes you against a wall, you bang your chest on the hard brick. "You know what I want so don't struggle or there will be consequences!" You whimper as his hands go down your hips. He stops all of a sudden and pulls away. You turn around.
"What do you think your doing to ((y/n))?" It was Sans! Dylan was hovering in front of him. One of Sans' eyes was glowing blue. Dylan seems lost for words so Sans asks you " Did he do anything?" Worry was in his expression. You shake your head and he sighs in relief. "What the hell is this?! Let me go you dumb monster!" Sans brings him close to his face. "Touch her again and you'll have a Bad Time!" Sans swings the front door open and throws him onto the hard ground outside.
Sans shuts the door then runs over to you. Your on the ground in shock. He hugs you and you just sob uncontrollably. "((y/n))... who was he?"
"D-Dylan he w-was my ex..." You say in between sobs. "W-we broke up b-because..."
"Yeah?" Sans looks at you with concern in his eyes. You take a deep breath and explain how you and Dylan had been going out for a few moths and he wanted to have sex but you weren't ready and you were a virgin. This is why you broke up. "He still has some built up anger about it so obviously because he was drunk he went to take it out on me. Sorry to drag you into this, it's my fault, this wouldn't have happened if I had just cooperated..."
"No! You don't have to be sorry! You don't need to do the things he wants you to if it goes against your morals."
"Thanks Sans." You hug him then pass out on his shoulder.
