Bruised To The Bone: (Sans x Reader)

"Oi! You two! Get your butts downstairs!" Undyne's voice cuts through the air. Sans and I both jump, his bony shoulder hitting my face. Undyne pounds on the door aggressively. 

"Ugh.. Um.." Sans sits up, me holding my head in pain. "Ah.. Sorry. We.. Fell asleep?" He asks.

"Yep. Guess so." I hum. Sans looks down awkwardly.

"Right. Uh, well.. I think that we should go meet.. Undyne.." I get up, Sans following. We teleport to the kitchen, hearing Undyne still at our door.

"Hey!" I shout. She jumps, and runs over to the living room. Sans and I collectively teleport right next to her.

"You punks really shouldn't do that.. You'll make someone accidentally murder you out of fear." She says, her voice irritated.

"Ya know.." Sans whispers. "She actually almost did that once.. I just barely escaped." I smirk.

"SANS! I THOUGHT YOU WERE WORKING! WHY WERE YOU NOT AT YOUR POST?" Papyrus yells.

"Agreed." Undyne spits. "You know, if you don't work, you won't get paid. And you won't be able to pay off that hefty tab of yours."

"I've been doing a ton of work." He smirks, and I know what he's about to say. "A.. Skeleton." Papyrus looks irritated, and Undyne rolls her eyes.

"Whatever. Just.. Can you actually try? If a human falls down, you'll need to actually help, and if you're rusty, you won't be able to." Sans smiles. I guess he knows that humans won't fall down.. Ever.

"Sure thing, bucko." He winks at me, face contorted into a face smile.

"Good," Undyne snaps. Her eyes light up. "So.. Lemme get this straight. You two were cuddling on the couch, then disappeared into Sans' bedroom for 2 hours.. And took a while to get downstairs. Explain." She stands, arms crossed, smirking. Sans turns blue, putting his hood up. My ears burn, and I feel a blush coming on. I put my hood up as well.

"We.. We weren't.." I stutter.

"Whaddabout the time that you and Alphys-" Undyne cuts him off.

"Don't you change the subject! What did you and (Y/N) do up there?" Her grin grows. "Or are you.. Not comfortable sharing it?~"

"We were listening to music. And playing video games." Sans says, not missing a beat.

"Yeah, right." Undyne scoffs. She pulls out her phone. It's identical to mine. On it is a picture of Sans' arm around me. Sans swipes at it. Undyne pulls it away. "Not so fast! I'll delete it if you tell us what really happened."

"Fine." Sans groans. "We slept together." His eye sockets widen, and his face is basically a blueberry. My face turns bright red. "N-Not like that! Like.. We fell asleep! Somehow!"

"Mm Hmm.. Don't believe you." Undyne taunts. She opens an app that vaguely resembles Instagram. Sans and I watch, wide eyed, as she posts the picture. Sans swipes at the phone again, and Undyne puts it in her pocket. Immediately, her phone starts to buzz erratically.

"Undyne.. Was that really necessary?" Sans groans. I bury deeper into my hood.

"Yes." She deadpans. Papyrus is grinning in the background.

"(Y/N), let's go game. I'm done." Sans grabs my hand and teleports into my cottage's living room. I look out the window, which is caked in frost. I start to shiver. Sans does as well. I check the thermostat. It doesn't seem to be working.

"Uh.." I flick the lights on, which fails. Sans and Papyrus' electricity was working, so I'm not sure why mine isn't.

"Crap.." Sans swears.  "Our generator.. We shouldn't overwork it.. Let's see.." He zones out, muttering numbers. I wait patiently. He looks at me. "Uh.. Ya wanna stay with us? I don't think that you wanna stay in a.. Cold cottage." He stares at the floor.
