Chapter Text
Satan's room was what he liked to call orderly chaos and no, this had nothing to do with Satan's vehement dislike of Lucifer telling him to clean up. He liked to get on the old man's nerves, alright? That was all.
But to keep the "orderly" in that chaos, sometimes he has to sort his books. Of course, everyone knew Satan liked to collect cursed books and the like, best of all himself. He knows each and every one he has in his room and can handle them with the necessary caution. Except, every now and then, Satan does mess up.
"I can't believe I touched the 'Forbidden Book of Cat Transfiguration' and turned into a cat!", he tried to say but all that came out of his mouth were meows. Familiar footsteps approached Satan because of course, this had to happen to him in the dining room where anyone could find him. He cursed his luck right as the brother in question found him. Loudly.
"Huh?", Mammon said when he saw him, "What's a cat doin' in the dining room?"
Satan could feel his hairs (fur?) stand on end. Why did it have to be Mammon? Before he could decide to run, the second-born pucked his brother up by the scruff of his neck. Satan panicked, what would his brother do now? He can't escape like this and there's no way to communicate! Frantic meowing could be heard but then, Mammon suddenly spoke in such a cutesy voice.
"Who's a cutesy wootsy little puddy tat?", he asked and Satan blinked up at him. What the-
"Mammon? What are you doing over there?" It was Mc! Satan tried to wiggle free of Mammon's hold. The demon sputtered, "Wha- nuthin'! Just found this little fella, ain't he the cutest?"
Mc looked over to where Satan the cat had just managed to get free and scrambled on the floor towards them, ignoring Mammon's exclamation. They kneeled down and smiled, holding their hand out to the cat walking towards them. He made a show of sniffing it before butting his head against their palm. Mc's face lit up in happiness, feeling like they have been chosen.
"You're right, Mammon", they say then, "He's the cutest cat I've ever met."
Mammon, however, was pouting next to them, grumbling about the cat not being so nice to him.
"C'mon, Mamms, I'm sure he will let you pet him too", Mc tried to cheer him up and shuffled to the side so Mammon could pet Satan as well. Guess I will let this slide, just this once, the demon-turned-cat thought.
Feeling both pairs of hands on his fur, scratching behind his ears and under his chin, rubbing his back and belly, Satan found himself purring and relaxing into them. He laid down and stretched himself out on the floor, completely lost in the sensation. The human and demon over him aww'd at this and Mc bent down to leave little kisses on the cat's head, laughing in delight.
Suddenly, a light shone from the cat's body and Mc felt like they were being pushed up and back by something like the cat was growing at an enormous rate under them. It happened too fast for them to yell out and so they found themself sitting halfway in Satan's lap, kissing the corner of his mouth.
A moment of silence fell over them before it was broken by Mammon's indignant sputters, immediately trying to get Mc off of Satan and asking his brother what the heck he thinks he's doing. Mc laughed and fought Mammon off, telling him they can move by themself.
Meanwhile, Satan still sat there shocked with his mouth opened slightly and a blush painting his face. During the commotion, he got himself together just a bit and looked over to Mc. They glanced over too and he's sure he did not imagine the little blush so similar to his own on their cheeks.
