(This happens after the events in Phantasmiafxndom's fanfic on Ao3 where Muzan is used to breed new demons for the first time :/)
Muzan sits there, in his cell that is so small that it feels crampt. His tired and terrified eyes staring into space as he thinks of the events that had happened. They used him. They made other demons touch him. He felt disgusted thinking about it. And looking down at himself he was horrified of what was to happen.
He was forced to stay as a woman for the purpose of actually making a demon. Muzan just couldn't figure out why do it this way, why not use his blood like they did so before? The demon just thought it was a cruel type of torture at this point. Did they even have to do that or did they want to see him suffer?
And this is where you come in, a scientist who was told to go check up on the demon and bring him to the examination room to see if he was in fact pregnant. Afterall if he wasn't they'd have to do it all over again. As you stepped into Muzan's cell his eyes were immediately on you. He didn't bother to hide the fear behind him. After all if the scientists did this to him, what would they do next?
"..."
Muzan doesn't say anything as he looks at you. He knows better than to speak by now.
