Maya Eto is 50 years old. She is a mother of two who runs an izakaya with her husband. She has been running the restaurant for 25 years since taking over from the previous owner. While working as a busty proprietress, she has been busy with childbirth, childcare, and housework without experiencing the joys of being a woman. It was only recently that her daily life finally settled down. The restaurant has overcome the crisis of the COVID-19 pandemic, and her children have safely become independent. However, as soon as she had more time to spare, her body began to change. "In the past few years, I have been unable to control my sexual desire..." After casually watching an erotic video on her smartphone, she not only became aroused every day, but her desire has only grown stronger as a reaction to her late blooming. Unable to be satisfied with her daily routine of masturbating with a vibrator, the busty proprietress finally shows off her I-cup huge breasts for the first time. She will fully release her hidden desires.
