The Darkness (Papyrus x Fem!Reader)

Undyne and Alphys

You're on cash register duty today because there's nothing for you to do in your department and the normal cashier is sick. You sigh as you stare at the empty aisles. Given the one coworker on janitor duty. Heh.... Duty.
All of a sudden, the front doors burst open and in (basically running) comes the new police officer Undyne. Behind her, the newly found inventor, Alphys. Undyne is wearing a brown tank top tucked into blue skinny jeans, knee high, black combat boots, her bright red hair in a pony tail, her badge hanging around her neck, and her belt holding her phone, pepper spray, gun, and taser. Alphys is wearing a light tan turtle neck with a black skirt and her trademark glasses and lab coat. The initial burst was loud enough to make your boss jump out of his seat. You know this because you heard him fall on the floor.
"HEY PUNK! WHERE ARE YOUR MEDICAL SUPPLIES!?!" Undyne says.
You simply point to aisle 10.
"THANKS!" She runs over to the aisle.
Alphys was behind her saying "U-U-Undyne! W-wait! H-h-h-he o-only has a l-little f-f-flu!"
"HE'S SNEEZING BLOOD ALPHYS! IT'S NOT A SIMPLE FLU!!!"
"Um..... Excuse me ma'ams?" You say.
Undyne looks at you from behind aisle 10. "WHAT?!"
"What exactly are your friend's symptoms?"
"H-he's sneezing blood, coughing a lot, has a high fever, and tends to puke almost everytime he eats." Alphys said.
You get out from behind the counter and go to aisle 10. When you got there, you saw Undyne looking frantically at cough syrups. You couldn't help but chuckle a little.
"WHY YOU LAUGHING PUNK!?"
"You're looking at the wrong stuff." You say.
"WHAT DO YOU MEAN?"
You walk farther down the aisle and grab a bottle of adult strong cold and flu medicine. You walk back to the two monsters and hand it to Alphys. "Mix a dose of this with some tomato soup or some porridge. Within a couple of weeks your friend should be back to normal."
"O-o-okay. T-t-thank you..." You saw she was trying to find a name tag. The problem with that is that the boss didn't issue name tags for your normal department.
"Oh. My name's [Y/N\Rosanne]." You tell her.
"[Y/N\Rosanne]."
"And no problem."
You go back behind the counter as the two monsters did some more shopping. When they came up to the counter, you scanned their items. The medicine, a can of tomato soup, and some ingredients to make spaghetti with. You scan their items and tell them the price. They pay and leave. You hear the tires of their vehicle as they leave and the beginning of Undyne's siren. You couldn't help but chuckle at their quirky ways.

Later that night, you were helping the new monster recruit close up when your boss came up to you.
"Hey there sweet cheeks~" He whispers in your ear. "After you help the new recruit. I have a special..... Job for you." You felt him leave.
"What was that about?" The recruit asks.
"It was nothing..." You look at his name tag. "Burgerpants... Nothing at all....." You trailed off.
Burgerpants just shrugged and went back to focusing on your instructions.
When he left, you went to your boss's office. As you open the door you hear him say "Ready for round fifty-three pet~?"
All you did was nod as you let him, once again, take advantage of you.

You walk into Grillby's to find him actually doing a karaoke night. You sit down at the bar and Grillby sets your usual down in front of you.
"Thanks Grillby." You went to feel for your wallet and realize that you forgot it at home. Shoot! "Um... Grillby?"
'Yes?'
"I forgot my wallet at home.. I promise I'll pay you.."
'Don't worry about it [Y/N\Rosanne]'
"Really?"
'Yes. I'll let this one slide if you sing a song.'
You look towards the karaoke machine and see a drunk Papyrus singing 'Pop Goes the Weasel'. You've honestly had enough of that song.
"Okay Grillby. I'll do it."
'Good. Cause your next.' You weren't prepared for that.
Papyrus finished singing and Grillby, somehow without you knowing it, got out from behind the bar and is pushing you to the machine. You search through the songs, some of the drunk guys letting out a whistle to you, until you found a song you know basically by heart.
(your song)

During the instrumental break in the song you closed your eyes and kept them closed through the rest of the song. Your mom used to sing this as a sort of lullaby when you had nightmares.
When the song finished, you open your eyes to complete silence. As much as you prefer silence, it kind of made you uncomfortable this time.
All of a sudden, Sans stood up. You didn't realize he was here. Papyrus got up with him, they started clapping. Then Grillby joined, and soon everyone's clapping at your performance. You couldn't help but blush a bit.
