Many of the monster pages say when they spot or see a man they like or fancy they rape him to be their husband. How does a monster fancy you as her husband so they rape you?
Well see when a monster girl loves a random man very much...
Your second question needs to be reworded. I can only guess at what you're asking.
I think he meant, how do mamono choose a man they will take as their husband. Whats behind the "a man that strike their fancy".
Honestly it's rpetty unclear, but it's hinted that mamono have some kind of 6th sense to tell if a man is "compatible" with her.
What do you think?
