Beastbound
I woke up and found myself transmigrated into my nemesis' doll. At first, I thought he was still a child at heart for keeping this. Then, I realized he was just unhinged. The doll's face looked just like mine.
And then the bigger surprise was that he was a beastfolk. Every night, he would torture me with his literal serpent tail. I eventually told him I knew what he was.
He imprisoned me on the bed and smiled at me gently. What came next were cruel words. "Since you already know, I'll drop the mask now. Tell me, do you want to use those toys or my tail?"
