Maya Etoh, a 50-year-old woman who runs an izakaya with her husband. She's a mother of two and has been running the establishment for 25 years after taking over from the previous owner. As a busty barkeep, she's been tirelessly working, juggling childbirth, childcare, and housework without ever getting to savor the pleasures of being a woman. Things finally calmed down recently. The shop weathered the COVID-19 crisis, and her children have successfully become independent. However, as soon as she had some breathing room, her body started changing. "My libido has been hard to control these past few years..." A casual look at an erotic video on her smartphone sparked a fire within her, and instead of just feeling aroused daily, her desires have been growing exponentially due to a late-blooming reaction. The busty barkeep, who couldn't be satisfied with her daily electric masturbation anymore, is finally revealing her I-cup breasts for the first time. She's about to unleash all her pent-up desires.
