Remember: everything Muzan Kibutsuji says is made up.

You were Muzan's wife.. Well, as you thought. Muzan only used you as a way to get closer to finding the blue spider lily- though he thought you were a great way to relieve stress once he was having a rough day. Today, was one of those days. He recently just came back from another failed attempt at finding the flower. You were in your room reading as he opened your door abruptly, a vein visible on his neck. "My dear wife, could you please come here.." He looked a you as his eyes were filled with stress and lust. He watched your curvy body walk up to him in such a way.. A visible bulge of arousal was forming in his pants. He paused for a moment before pointing at his bulge speaking with a rough and demanding voice. "Suck."
