I would like to request yandere Papyrus fontcest please!
Papyrus brought Sans’ jacket to his nose. Inhaling the scent. The saccharine fragrance was lolling his senses; he could feel pseudo-flesh manifesting from beneath his trousers. Already.
For the first time in forever, Sans had thrown his dirty laundry into the hamper. Papyrus was—ecstatic. And yet, curious as to why.
It was rare for Sans to toss his shorts into the pannier, much less his entire wardrobe—especially his jacket. Something Papyrus never had the chance to wash. Ever.
Perhaps Sans was getting another job? Although it was strange to consider him adopting a new duty to his already busy schedule. Regarding as to how many jobs Sans was currently balancing at the moment, It would be odd—or just plain stupid—to get an extra one.
Gently, Papyrus lowered the garment. Eyeing the defiled azure fabric. Peculiarly.
Maybe there was a special occasion coming up—a birthday? Gyftmas? April fools even?
Papyrus shook his head. His thoughts were getting the best of him; he was thinking too deeply about this. Most likely, Sans just—thought his clothes needed a wash, that’s all.
Yea, that’s it. And besides, Papyrus should savor this moment. It was an uncommon one, after all; he wouldn’t get a chance to be so intimate with Sans’ clothes for a long time after this.
He raised the jacket back up to his nasal. Taking another whiff of the soft material, he filled himself with Sans’ cloying scent.
“SANS.” He groaned, letting the ‘S’ drag out. Of course, Sans would be here. Why hadn’t he thought to look for his brother here in the first place?
Swiftly, he nudged open the bar’s door. The immediate warmth of Grillby’s cozying up to his parky bones. It was vast compared to the quiet, wispy chill of Snowdin.
The familiar faces and voices of the dog sentry greeted him. As well as the other bar patrons. However, Papyrus had no time to bother with them. He needed Sans home; it was getting late.
It didn’t take any effort to spot his brother. He smiled brightly as he heeded that known jacket.
Right in the center of the bar, perched up on a stool, was his brother—
Sans, who was—cuddling with Hopkins, had her arms wrapped around his boney neck as their laughs outweighed every other patron's vocals. They were so close. So—carnal.
Papyrus blanched. Stepping back an inch. And then another inch. And another, until the bar door slammed shut on its own. He flinched hard.
The whole world became hazy. Why was she so close to him? Why was he letting her touch him like that? Even around Papyrus, Sans was sensitive about his neck. About touch. So why did—
Papyrus stalked back to his house. Unable to hide the globs of tears blurring his vision, He was unable to pick up his phone and dial Undyne’s number. He was unable to call out to his flowery friend and cry and whine to him.
He was unable to stop his soul from burning. Burning from—what felt like—betrayal
Papyrus clenched his teeth. Barely able to look at his brother—his betraying, backstabbing brother.
He sat on their lumpy couch, with one knee atop the other as he sat ornately. Trying not to burst into tears at the sight of a lipstick smear tinseling Sans' clavicle.
“Sup, bro,” Sans giggled, limping towards the furniture. “I was wonderin’ where y’where.”
He staggered to the floor, far too drunk for his own good.
Papyrus scowled, almost disgusted. A part of him wondered if that bunny roofied Sans’ drink. Another part regarded that his brother had just been careless with his alcohol tonight.
“Ya shouldn’t stopped me, Papyrus.” He hissed, flipping over to lay on his back. His dozy eye lights bore into Papyrus’s hollow eye sockets.
His hand was raised above his head, reaching for Papyrus.
“Alp me up.” He winked drowsily.
With a quick motion, Papyrus snagged Sans’ hand. He yelped. Startled at the pull. He was lifted off the ground so quickly.
He was face-to-face with his brother, who was giving him a fierce, sharp glare.
“What’s with th—“ Papyrus shoved his face into Sans’, their teeth clanking together. Harshly. A red ecto tongue lapped at his teeth, making Sans gasp. Papyrus tasked it as an entrance. Pushing it inside his brother’s mouth.
The ticklish sensation of something running through his mouth forced Sans to form his own tongue.
He balled his clammy hands into fists. His drunken mind not even processing what was happening—Papyrus was kissing him? Papyrus was—
He screamed, his voice overcast by the sloppy kiss. Their tongues rivaled, Papyrus’s ruling over his.
The wet organs intertwined. Mixing together into a flurry of purple saliva.
Papyrus’s hand groped Sans’ neck. Trying to appear more like lovers.
Sans let his tongue fall flat, losing the energy to shift the ecto around. Papyrus beamed, exploring his big brother’s mouth.
Eventually, Papyrus pulled away. Panting; exhilarated from their make-out. He gave Sans a cheeky grin.
“YOU’RE MINE. YOU KNOW THAT, RIGHT, BROTHER?” He lifted Sans’ into his lap.
“What—what are you—what?" Sans couldn’t form a sentence. This was—all too much.
“THAT DISGUSTING RABBIT—SHE’S TRYING TO TAKE YOU AWAY FROM ME.”
Papyrus nuzzled his jaw to Sans’ neck. He embraced his brother. He warped his arms around his back, securing him. Keeping him locked within his grasp.
“SHE DOESN’T DESERVE YOU. SHE DOESN’T KNOW YOU LIKE HOW I DO!” Papyrus hummed. Sans’ eyelights dispersed. His brother was talking about Hopkins.
“HOW HORRIBLE OF YOU TO LET HER HAVE YOU, ASWELL.” Those brooding arms squished Sans from inside of them. “DON’T WORRY. I FORGIVE YOU, THOUGH.”
“I’LL ALWAYS FORGIVE YOU.”
“YOU BELONG TO ME. NOT HER—NEVER HER.”
“I LOVE YOU SO MUCH—SO MUCH. WHY CAN’T YOU UNDERSTAND THAT?”
“Because I don’t love you like that!” Sans howled, clawing at Papyrus’s battle body. His brother fell silent.
“Yer my brother,” he murmured. “I like ya as my brother.”
“Papyrus.” Sans whispered. Burying himself into Papyrus’s scarf. “Let’s just forget about all this.”
“IT’S BECAUSE OF HER, RIGHT?”
“IT'S OKAY. I DEALT WITH HER. YOU’RE TOO DRUNK TO KNOW WHAT YOU’RE TALKING ABOUT, SANS.” Papyrus chortled, rubbing circles into Sans’ back. Sans opened his mouth to deny it—yet he didn’t.
He hadn’t realized it at first, but Papyrus’s scarf smelled a lot like dust.
Thank you so much for the request! I hope you enjoyed this!! (I didn’t get this beta read—so sorry if there’s any mistakes)
