Flipping the script(swapfell)part 1

chapter 16

Slyrr, a Monster in the Royal Guard, had cornered Papyrus in the labs while on his rounds to gather up reports and was propositioning his former Captain to his face.  Sans didn't know exactly WHAT was said, but when he turned the corner and saw the Monster touch his little brother's face with those FILTHY claws--

He just saw RED.

One HP and a third of the Guard's size be damned, he had a running start before barreling into Slyrr, tackling him to the ground and attacking with his fists, his magic, his bone constructs--ANYTHING to inflict as much pain and draw as much blood as he possibly could.  Slyrr had apparently drawn out his fist to retaliate and Papyrus grabbed Sans away to avoid Sans getting hurt.  In a fit of blind rage, Sans had bashed Papyrus in the skull with a bone construct to the point of cracking his skull before coming to his senses.

After the RED, Sans remembered standing in the hallway with a large bone in his hand, Slyrr struggling to get up off of the floor, and Papyrus leaning back against the wall with his skull cracked and dripping marrow, eyelights flickering in a daze.  Sans looked down at his bone and saw it stained with marrow, his BROTHER'S marrow. 

He was SO close to having a nervous breakdown, but Papyrus lowered himself to his knees and turned his head to its uncracked side.  "...may I have another, m'Lord?" he asked, his voice dripping with desire and NEED.  The kind of NEED that Sans hadn't heard since Papyrus was last sane, and for a moment, he felt deeply touched that he had been able to bring that spirit back for the moment.  Sans reached out and touched his hand to the cracked section of skull, swirling his phalanges in the marrow and seeing Papyrus let out a rattling purr and nuzzle his hand.

He was snapped back into reality when Slyrr shot at them that they were 'disgusting freaks', and Sans was honestly more angry over the ruined state of his and Papyrus's moment than his little brother's bashed skull.  He sent a volley of bones at Slyrr until the Monster was tripping ass-over-tit to get out before taking Papyrus to his office to fix him up.

Guilt bubbled in his soul as he gathered up what he needed to help heal Papyrus, which would take some time with that sort of head wound considering he used most of his magic reserves beating the shit out of Slyrr.  He kept berating himself, hating himself for getting Papyrus caught in the crossfire of his temper again and again--and this time Papyrus might have a crack scar to show for it! 

"...I'm sorry, Papyrus," he said quietly, dabbing the red marrow away.  "I really fucked up this time...shit, and if Slyrr goes to Toriel about this--"

"I'll tell her the truth, m'Lord," Papyrus quietly cut in.  "I'll tell her I like it."  He leaned his head against Sans's hand again, nuzzling it lovingly, his bones rattling with purring again.  "I'll tell her I welcome m'Lord's blows...that I willingly shed my marrow for you because it brings me pleasure."  His eyelights flicked up to Sans, shining brightly albeit still dazedly.  "...because it really IS the truth, m'Lord.....this..."  He reached up, pressing Sans's hand against his cracked area more firmly.  "...really DOES make me feel good..."

"Papyrus..."  Sans pressed his phalanges in deeper, feeling the cracks and chips shift slightly.  "...you're being truthful?  You're not just saying that to please me?"  Papyrus nodded, his breathing slightly rattly.

"I would never lie to m'Lord," he purred.  "I WANT it"

Sans leaned forward, pressing his skull against Papyrus's.  "...then I'll give it to you," he said.  "But I want you to be mindful of your HP, Papyrus.  If it goes below five, I want you to tell me."  He paused.  "...You'll tell me 'game over'.  Understood?"

Papyrus nodded.  "Yes, m'Lord," he agreed, then paused as though thinking about something.  "....I am only at thirty-one now, m'Lord..." he continued, hardly bothering to keep the slyness out of his voice.  Sans snorted at the lack of discretion paired with the puppyish expression Papyrus was giving him.
