Both your eyes widen at the sound of Frisks voice.

"Get off each other, will you? It's kinda disturbing..." Frisk mutters annoyed at the fact that you and Sans were on top of each other.

You both awkwardly shift about so that Sans was no longer on top of you. Then, you both make your way to sit at the end of the bed so that you're facing Frisk.

"You're a cunt, Sans." Frisk spits angrily.

Sans eyes widen and he has a confused expression on his face.

"What do you-"

"I WAS GOING TO TELL YOU THAT I LOVED YOU SANS!" He roars as tears stream down his cheeks.

Frisk stands up from the stool with his jaw clenched.

Sans looks at Frisk with his mouth ajar, not really knowing how to respond.

"I hate you Sans. You make me feel so special and happy. You make me want things that I didn't think I'd want. I didn't want it. But now, you've made me want to need it."

Frisk looks away ashamed.

"Frisk, I didn't know..."

"Lier." Frisk scowls, becoming rather annoyed. "If you didn't know, why would you lead me on? The second night I was here was a great experience. I'm pretty sure Y/N would love to hear it."

Frisks scowl was replaced with a sneaky looking smirk as he folds his arms across his chest.

Sans stands up, his eye burning yellow.

"You asked for it, kid." Sans says angrily.

"I asked for you to show me my soul, not turn me on, you dick."

Your eyes widen in shock at Frisk words as you look to Sans. His face portrayed so much anger, his skull could of exploded at any second.

"Frisk, I'm warning you." He mutters, starting to get frustrated.

"It's a good story though, don't you think?" Frisk says with an annoyingly fake smile.

It was enough for Sans to use his magic to pin Frisk up against the glass door.

Frisks body collides with the glass with a thud. He bites his lip trying not to let a sound of pain to escape his lips.

Sans walks up to Frisk slowly.

He turns to face you with a small smile.

"Do you want me to show you what happened, Y/N?" He asks you sweetly, his eye still burning yellow.

You purse your lips, not knowing whether it was a good idea to let this happen.

Your head slowly nods as your curiosity gets the better of your mind.

"Alright then."

With that, he turns around and you can see Sans face close to Frisk as he lets out a breath on his face.

You couldn't help but feel jealous that Frisk was the one pinned up against the door and not you.

Frisk whimpered at Sans' actions and seconds later, a red heart popped out in front of Frisk.

Sans stopped using his magic and Frisk fell to his knees, slightly panting, with another thud.

Sans turns to you again.

"This is the safest way for someone to show you what your soul looks like. He asked for it, I showed him his soul." He says blatantly.

"You really are a dick Sans. I don't know why I'm still in love with you." Frisk  mumbles to Sans as he keeps his eyes to the floor.

A question arose in your mind, and your mouth decided to speak.

"Frisk, why do you flirt with me?" You ask, curious as to why Frisk acted the way he did.

Frisk sighs shakily before opening his mouth and speaking.

"I wanted to make Sans jealous. I thought maybe if he saw me and you together, he'd realise that he had feelings for me and not you. It was stupid of me really." Frisk confesses sadly.

"Yeah, it was stupid of you." Sans says, rolling his eyes.

Frisk looks up to Sans, looking weak and hopeless. Slowly though, his mouth shapes into a wide smirk.

"No, you're stupid. Fun fact Sans, Y/N isn't even human. She's a monster that looks like a human. How's that for stupid, you fucking twat."

Frisk picks himself up from the floor before storming out the room and closing the door with a rather loud bang.

Sans looks over to you, realisation all over his face.

"You're a monster."

You could feel your insides churn slightly at the words. There's no way...

Sans walks over and lays himself down on his bed facing upwards.

"It all makes sense. Why your soul won't come out during a battle. Why you have magic. Why your soul won't come out in a vulnerable situation..."

He places his bony fingers on his skull, clearly shaken up by this information.

You too, were shaken up.

All your life you thought you were human, just a bit different.

There had to be some sort of confirmation to this. You didn't even know what your soul looked like.

"Sans, how can you tell if I'm actually a monster?" You say confused and slightly scared.

Sans slowly sits up and crawls over to where you were sitting.

"I can show you, if you want." He whispers sensually into your ear.

Your body shudders at his words and you nod your head slowly. You trust Sans, right?

"I won't do much, okay?" He says reassuringly before pulling you into his lap.

His arms wrap around your waist as his yellow tongue slides across your neck, leaving behind a trail of bright yellow saliva.

Your head rolls back in pleasure, liking the feeling of Sans' tongue against your skin.

He keeps going at it, licking all over the sensitive skin on your neck until you could feel something leave your body.

Sans' licks stop and you whined slightly, not wanting to him to stop.

"Look, dove. Your soul is white." He says quietly.

You look down to see a a white upside down heart floating in front of you.

"I guess you really aren't human."
