Emi, her stepfather, and her stepbrother lived together as a family. Emi's mother had already passed away. One day, her stepbrother suddenly declared that he wanted a baby brother, which initially shocked Emi and made her resist. However, her body betrayed her, responding to his advances. Driven by intense desire, her stepbrother passionately pursued fatherhood, repeatedly pleading with her: "I want a baby! Give me more, more sperm! Fill Emi's pussy with sperm◆" Their relationship grew increasingly intimate, escalating into a full-blown affair.
