Three Girls and The Mansion Of Skeletons ( Reader X AU Sans and Papyrus)

Chapter 10: Cry Babies

You woke up the next morning to loud shouting from downstairs filtering in under your door. You groaned, not really wanting to open your eyes. You rolled over and checked your phone.

10 missed calls from your sister.

It was half-past eight in the morning and she started ringing you about 6? Fucking hell, lucky that your phone had been on silent.

You looked over to see if Tilly was awake, finding she was still asleep you smiled and got out of bed slowly to get changed out of your PJs.

The shouting got louder and you sighed, running downstairs. "UGH! WHAT THE HELL IS WRONG WITH YOU GIRLS? SHARING A HOUSE FULL OF MONSTERS! THAT'S SICK!" You frowned, that was your sister shit...

"Hey! How dare you? Bitch that is fucking rude! Mind your manners in other people's houses!" Suzy growled back raising her fist as Mae just stood there in silence, stroking Neko in her arms.

"What the hell is going on?" You demanded, angrily crossing your arms. You were not going to let your sister pick on your friends.

Your sister turned to you and smiled. "Ah Y/N, thank god. This is your job? Living with a bunch of male skeletons with your posh friend and bitch blonde friend? Really, what a stupid disgusting job!" She crowed, laughing.

You clenched your hands into fists as you saw Papyrus, Blue and Reap watching from the kitchen. They had worried looks on there faces.

The others must be still asleep and Horror and Crook must not be here yet.

You sighed. Sis, can you not be rude? Thank you. I'm helping out my friends and the skeletons ARE my friends." You were getting really tired of your sisters shit now. You finally made up your mind, she was not going to take Tilly. She and her dickhead boyfriend were not fit to look after the kid. Lucky you knew Tilly's grandparents, her mum's parents of course. You were going to ring them and let them look after Tilly so you knew she was going to be in good hands.

Your sister scoffed you felt your patience for her wearing thin. "That's funny, I thought you were scared of skeletons?" She smirked.

You were about to shout at her until Suzy punched her in the face. "I've had enough of your mouth!"

"ACK-"

Suzy then grabbed your sister by the hair and tugged to pull her up. "You need to respect your sister! You're the one who made her scared of skeletons!" Suzy accused as she threw her back down.

Your sister stood up and wiped her nose as she glared at Suzy "I-I just came for Tilly."

"Get out my house before Horror and Crook show up," Mae mumbled.

You shook your head and glared at her. "No, you can't have Tilly. You and her asshole dad are not fit to look after her. I'm calling her grandparents." You explained as you walked up to her.

Her eyes widened as she stared at you. "What? You can't do that Y/N! You have no right!"

You scoffed. "Yes, I do. That little girl has been so happy here, I haven't seen her like that ever!"

Your eyes widened and your head jerked to the side as you felt a harsh sting on your cheek.

Mae and Suzy gasped as Mae held Suzy back. "WHAT THE FUCK!?" Suzy shouted, struggling in Maes hold.

You slowly turned to look at your sister again as you felt hot tears run down your face. You were surprised, angry, shocked and sad, your sister slapped you, she... she's never slapped you...
