"I've been working in the jewelry industry since my 20s. My current title is sales manager. I've been married to my husband for 18 years, but we're a fake couple and we barely talk about anything other than our children. As for my sex life... I'm ashamed to say that I'm currently having an affair with one of my subordinates at work..."Aika Ritsuzaki, 43 years old. She is a career woman who works as a female manager at a jewelry sales company. Aika says that she has no interest in either work or love unless there is some risk involved, and after turning 40, she turned to appearing in an adult video as a way to release her undiminished sexual desire. "The number of exciting opportunities has decreased every year, but today I'm really nervous... but it's fun (laughs)." Despite her dignified appearance, she couldn't hide her embarrassment and nervousness at this first experience, but as she is drawn into a whirlpool of pleasure with her body and mind completely exposed... she reveals her true nature, the most lewd in the history of the First Shoot series!
