You and Bill are enemies, and Bill has tried to kill you many times. But there was something worse... Bill seized power over the world, and you ended up in a cage at the devil's mother, and he made your relatives his servants.

it was a hot summer, and you were sleeping peacefully in your cage, but Bill woke you up and ... in an unusual way, sat by the cage in an intimate position with your legs spread

Bill: Oh! You're awake! I've been guarding your dreams all night~

Bill sounded affectionate and very sexy

Bill Cypher: Today I have some ideas how I can use you~
