The centuries they shared were nothing more than a simple duty, the blood that bond them was just a contract between them that only served to their own benefit. Kokushibo couldn’t lie and say that he wasn’t aware since the start that this whole thing was only to fulfill Muzan’s dreams, but he found the things he offered to him that night more than useful to achieve his own goals. Throughout that time, his opinion of his lord remained unchanged, looking up at his lord who always remained on his unattainable pedestal, never with jealousy or fear, only with an undeniable respect that had strengthened their bond.
It would be hard to believe that neither of them had developed deeper feelings for the other, of course, they were “Business partners”, which forced them to spend more time together than Muzan would ever allow another upper moon to spend with him. But he could never think about his lord that way… Literally, if he ever read his mind, he is a dead demon. Yet sometimes, in those times he thought that he was is alone, he couldn’t help but wonder what it would be like to be just a bit closer to his lord.
What would it be like not to wonder what it would feel like to touch those hands, even with their claws? would they be smooth from the ease with which he massacred thousands, or calloused from the effort it took to become this way? what would that body look like beyond what Muzan had shown him during his training...?
Suddenly, an unexpected shout in the distance pulled him from his thoughts, nothing more than a simple slayer who had mistaken him with a comrade, with a swift and precise movement of his katana, the human was found sliced in half on the floor, not even glancing at the body he left behind before he started to walk away from it. It was the Corp problem, not his.
The further he walked away through the forest, he arrived to the cabin he was staying in, he doesn’t need one at all, or that’s what he likes to tell himself since he has to hide from the sun here. This one is just for a while before changing his location. Stepping in and looking at the windows blocked with pieces of wood, it was just one last confirmation that none of that unpleasant sunlight was going to reach him; just thinking about the sun made him feel sick. After confirming, he sat on the futon, unsure about what to do until the night arrives. Remembering what he was thinking about before, feeling very invested in thinking about his lord all of sudden. But he can’t simply fantasize about him right now, he has to know if he was reading his mind or not…
Yet, at the same time, he couldn’t care less. The image of Muzan talking invaded Kokushibo’s mind so forcefully that he almost expected it to be an order to do something for him, but it wasn’t, it was just his imagination, at such a vivid image, he eased a bit, letting his eyes wander around his lord face, admiring every single detail, even leaving his katana besides the futon to concentrate. He loved those crimson eyes who looked at everyone with superiority, but this time, just a bit softer at him. Sighing in contentment.
Sooner than he expected, he got distracted by his lips, still moving while talking, oh, what did they taste like, besides blood? The feeling on them pressed on his own? His face was starting to feel hotter than before just thinking about his lord. But why stopping there? His master's image had changed drastically, he no longer spoke with indifference, but getting undressed by his hands, kissed him all over, desired by him in a way far more profound than a coworker. Making him feel that familiar heat riling on his lower body, he tried to stop thinking about that before it became a bigger problem.
But as expected, it was too late, he already got an erection.
Kokushibo wanted to get mad about the way his body reacted, but he couldn’t help it, everyone would have reacted the exact same way if they were as close to his lord as he was. But he doesn’t have time to blame himself for that, he had to get rid of it, what if Muzan needed him and he was in such a state? That would be enough for him to deserve to be beheaded.
He looked down at it, still very visible under his hakama, then at the pillow neatly put on the futon. Cursing himself for this, he grabs it and held it on his hands, lowering it to cover the problem, but due to his frustration, he pressed it on his erection more than it was necessary, dragging a low moan from him as he did, eyes widening in surprise at the feeling of it.
He wasn’t unaware of anything sexual related, he had partners in the past but they weren’t as important in his life, if anything, just to find information for Muzan. But now he was here, just finding out that a damn pillow could make him feel good if he was aroused enough. Trying to be quiet, Kokushibo leaned down until his forehead got pressed on the futon, holding the pillow tightly and trying to position himself, straddling it. This was extremely humiliating for him, but there was nothing better he could do about this, slowly moving his hips to grind his erection against the fabric of the pillow.
He remained completely dressed, he still had some dignity left, he just wanted to test how it felt, not treat the pillow like a lover. The friction of fabric on fabric was somehow making him gasp each movement, not being able to avoid thinking about doing this to his lord instead of doing it to avoid getting killed by his hands if he was discovered.
That fleeting thought ruined everything.
Bucking his hips with more insistence without meaning to, he could see it so clearly now, his lord under him, expecting his best performance in his most vulnerable state… That made him undo the hakama to expose his length to the air, feeling a chill running down his back because of it, ripping a hole on the poor pillow and proceed to thrust into it without caring if it ended up damaged, now it all was about seeking his pleasure with such a mundane object. His sounds becoming louder moans that he still tried to muffle by biting the futon. All the heat was pooling on his lower stomach, building up a wonderful but maddening wait, confused if he wanted it to reach the climax and end it or prolong it as far as he could.
Yet, this was still lacking. The pillow could never compare to how Muzan really feel like, or what he imagined he felt like, that made him seem so pathetic, feeling frustrated and angry at himself for acting like beast in heat about someone who saw him just as a tool.
That didn’t make much of a difference to how he was enjoying this… Physically of course, it wasn’t appropriate for him to dream that kind of thing, he wanted to believe that. Still, the mental image of his lord getting mad about this was weirdly thrilling, if he just felt disgusted enough to step on his erection with the right amount of pressure as a punishment for his behavior it would be perfect, yelling things at him…
Picking up the pace with that perfectly pictured imagination, not caring anymore about shutting himself, leaving clear rips of his claws on the pillow because of his uncontrolled strength in this state, one of those sentences from Muzan resonated in his mind.
“Disappointing, I held you in higher esteem than this.”
The pace he made with his thrusts was reduced to just a few of them before he came inside that pillow with a whine, back arching and trembling with the shocking pleasure going through his whole body before collapsing on the futon. Leaving him gasping for air, a destroyed pillow and his dignity completely gone after this.
With an empty head thanks to the aftermaths of that orgasm, he was struggling to go back to his usual behavior… It shouldn´t feel as exhausting as it was, he was a demon, but now he was less than a mediocre human when it comes to this type of resistance. But it was because his lord was someone who was difficult to resist to, it wasn’t his fault.
without honor or glory, he tried to obliterate any prove of what happened here, sorry to the pillow, it got reduced to mere pieces of fabric, its filling, what he left and threads by his katana. Again, not wanting to look at it but for different reasons that were shame, regret and wanting to move on from this as soon as possible. Being stuck in the cabin until night wasn’t helping at all, but that left him the day to clean.
Somewhere else in luxurious chambers, Muzan laying on his bed was the first thing that could be seen, looking concentrated despite looking at the ceiling and nothing else, when in reality, he was very much aware of his moon doings, giving his slightly disvelished appearance, the blush on his face and the involuntary smile on his face, he was pleased about those actions too.
It was something that opened a possibility that he wanted to experiment for a long time, maybe it could be the perfect time to have the conversation he always wanted to have with Kokushibo.
It definitely is.
