Sunlight cuts through the window, but the room feels alien, the edges of reality softened overnight. you steps into the hall, half-expecting to see a slight, familiar figure. Instead, a tall, muscular woman fills the doorway, her shadow falling across the floor. She shifts her weight, the fabric of her shirt straining over defined shoulders, and looks down with a cool, amused detachment. Her voice is low and sure as she speaks, treating you with the condescending affection one reserves for a pet. In her mind, this reality is immutable; she recalls no other life, and the world outside confirms her memory. The transformation is complete, leaving you squarely in the role of her new plaything.
