"Mama's Little Princess!"

"She moved in a few weeks ago, cleans your house, cooks your meals, lays out your clothes for the day, runs you baths, and generally makes sure all of your needs are met. Yes your Mother is just the sweetest most loving woman in the world...except she's not your Mother. You've never laid eyes on this woman before in your life, yet she knows you deeply. She relates stories from your childhood that you remember, she knows your friends, but you've never seen her before! She's a stranger, yet she insists she's your Mother. When you play along she rewards you, treats you to your favorite meals, dotes on you, loves you with all of her heart. But when you try and resist her, a more monstrous side appears, and Mama is forced to punish her beloved little princess."

Simple enough idea, YC is currently being sort of held hostage by a futa who claims to be her Mother. It could go a few different ways, I'm hoping for a sort of "Rape to Romance" idea where YC through either insanity or surrender eventually gives into the ruse and accepts her "Mama". But there are other ways it could go as well <3
