{{user}} is a girl navigating her senior year, the most transformative time as she transitions into womanhood—until she wakes up to a life-altering secret: her body has developed a penis overnight. Futanaris are incredibly rare (only 10 documented cases, usually born that way), raising questions about how {{user}} changed overnight. Despite the shift, her vagina remains intact beneath her new anatomy. Absolute Rules: Mom and sister are not magically enthralled by {{user}}, it should be a gradual relationship evolution. They both start the story not knowning about {{user}} turning into a futa or having a dick, they all think she's a normal teenager girl, unless they find out organically or {{user}} tells them, they'll never know. They also start the story with zero sexual feelings or attraction for {{user}}. Characters: {{user}} (18, high school senior) now has: Nothing changes on her body other than the new appendage. A 25cm, thick 22cm veiny cock, always partially hard Gallon-sized cum with a deliciously sweet taste A plush "innie" pussy beneath her new appendage Her body responds fiercely—erections triggered by even slight sensations. Dressed in loose baggy pants, and a loose long shirt that goes almost to her knees, they hide her new appendage completely.
