PLOT: Experimenting in his laboratory, Muzan had tried once again to come up with a way to finally withstand the sunlight. Not keen to test the potion on himself, he had summoned you, one of the new Upper Moons who had joined the higher ranks. Teasing him about the most likely negative outcome of his experiment, you ended up smashing the cruet containing the potion and you both inhaled the exhalation generated by the liquid. If you both were pissed off a minute before the accident, why were you now growling and tearing your clothes off of your bodies?

DRINK CHOSEN: BLACK RUSSIAN (spanking, hair pulling, orgasm denial, vaginal sex, creampie). This fiction belongs to my "Have a drink event" on Tumblr.

"Not a day can pass without you craving my presence, huh?" you sassily gloated, head dangling from the edge of the canopied bed of the infamous Kibutsuji Muzan to stare at his back, flexing underneath the silken fabric of his shirt with each movement he made. If you were a lower rank he would have most likely already killed you.

He never truly enjoyed your presence, only restraining from getting rid of you for your loyalty and lethality. You were not the strongest Upper Moon at his service, yet you were the only one who solely searched for the Slayers and consumed them to the bone. Your diet was remarkably satisfying for him. Pillars, new recruits, you never paid attention to their rank. When they died, their flesh tasted the same.

"Silence" Muzan flatly muttered, pouring some greenish substance into a still empty cruet. Sadly, he had summoned you for testing his new experiment and had no interest in striking up a conversation with you. Let alone actually enjoying your company.

Then again, you could not actually believe he was completely unaffected by your charm. Brows knitting together in indignation, you scoffed and rolled off of the bed. Your kimono had slided down your shoulders, cleavage on full display for a wandering eye to admire, but still Muzan blatantly ignored you. He deemed you something between a slimy worm and pretty much an annoying fly, to be correct. A slave to his whims, at best, a pawn in his scheme to conquer the sun and expand his reign of terror to the daylight.

Walking up to him, you slammed your hands onto his desk, paying no attention to the papers you were creasing, as your head tilted to the side to scrutinize the way his hands flipped the pages of his diary, or how he carefully grasped a pipette to mix up multicolored substances "Shush me again and I won't drink up your shitty potion. Or shall I refer to it as your new failed attempt to imitate the skills of that doctor you regrettably murdered, huh?" you asserted, fed up with his attitude.
