Yandere Big Brother’s Baby Love Dependency

Synopsis

Quit being an adult! This KU100-featured audio work pairs a possessive step-brother with infantilism roleplay for an intense experience. Your caring step-brother, who has looked after you since childhood, uses a soothing voice and baby talk to regress you into a childlike state. If you perform well, you receive rewards; misbehavior earns gentle scolding. This beginner-friendly content features a yandere character who employs suggestive brainwashing techniques to guide you toward complete regression. Yudzuru, a 25-year-old childcare worker and your current roommate, remembers your childhood promise to marry him. After you express independence, he uses sedatives and confinement to reawaken your childhood feelings, believing a shared world of happiness awaits. The content includes numerous intimate roleplay scenarios designed to deepen infantilism and pleasure, featuring baby talk, physical affection, and age-regression dynamics throughout.
