"Wha—? Nii-chan?! Why are you here?!" Though meant to support the household, her stepbrother's lack of work left her unable to cover her mother's hospital expenses, forcing her into working as a soapland girl. The family budget sank deeper into the red every day. Relying solely on her husband's income had its limits—she had no choice but to earn money herself. One day, her assigned customer turned out to be her stepbrother. Threatened with exposure of her secret job, she was reluctantly forced into mattress play and full-body washing. His treatment was harsh, showing no intention to please her, and ultimately, he creampie'd her. From then on, she was compelled to serve him daily, trapped in a situation where refusal was impossible. And amid it all, she finally reached climax.
