Underfell Papyrus x Reader

The show cut to commercials with a burst of static.

You shook your head, scoffing under your breath. Of course, she's stirring up drama... It's what she does. But for a moment, something in you paused. Why did you care? Why should it matter if she dragged his name through the dirt? After everything he'd done to you, the scars, the threats, the years of being treated like less than nothing, he deserved worse.

With a sigh, you unplugged the vacuum and looked around. The living room, for once, was spotless. No bottles, no trash, no flipped furniture. A stubborn stain near the TV refused to come out, but compared to what it was before... it felt like a victory. Your tail flicked, ears perking up as a small smile tugged at your lips.

Of course, the moment didn't last.

The front door slammed open with a crash, making you jump as Papyrus stormed inside, the floorboards groaning under his boots. Sans followed a step behind, hands in his pockets, that smug, half-lidded grin plastered across his face like it was glued there.

Your heart dropped. Ears flattened, and a low growl threatened to escape your throat when you caught Sans's eyes.

"YOU GOOD-FOR-NOTHING SACK OF SHIT, SANS!" Papyrus roared, his voice rattling the glass in the window.

Sans sighed, unbothered, and made his way upstairs without a word. Business as usual. Then Papyrus's gaze landed on you, and the vacuum was still sitting in the middle of the room.

His scowl deepened. "Pet! Why is the vacuum still out?"

Your throat tightened, tail instinctively curling around your waist. You could already feel the threat of punishment in the air like a storm gathering.

"I...I was just finishing, sir." You muttered, quickly lowering your gaze.

For a brief, bizarre second, Papyrus hesitated, something flickering in his expression. But it was gone as fast as it came.

"Put it away, you filthy mutt." He spat, the words sharp and acid-laced, as if speaking them might burn the feeling out of his throat. His glare pinned you in place, cold and storm-dark, but behind it, something flickered. Something raw.

It wasn't just disgust. It was fear. It was ache. It was something tangled and unspoken that made his voice crack at the edges, made his teeth grit like he was choking on his own words.

"Before I rip it off your worthless carcass." But even as the words left him, he didn't move.

Because no matter how much he wanted to hate you, wanted to bury you under every cruel word he could muster, some cursed, wretched part of him couldn't stand the thought of you being gone.

And it was eating him alive.

You forced yourself to move, fingers stiff as you began wrapping the cord around the vacuum. Every click of the spool felt deafening in the tense silence.

At least, no punishment. Not yet. As you hauled the vacuum toward the closet, the television cut back from commercials, Mettaton's velvet voice purring through the room once more.

"And now, my darlings... the secret Papyrus doesn't want you to know." She teased.

You rolled your eyes, biting back a scoff as you reached the closet door. Of course, she's still at it.

From behind you, Papyrus grunted. "Hurry up."

You didn't answer. You didn't have to.

But as you pushed the vacuum into the darkness of the closet, your ears twitched, catching Mettaton's next words, and what she said made your blood run cold.
