45-year-old Akagi Mina is the beloved proprietress of a local set meal restaurant, known for welcoming customers with a warm smile and her big tits. As a part-time housewife, she has skillfully balanced family life and work for years. But last year, an affair with a regular customer drastically changed her mindset. After just one encounter, Mina awakened to the pleasure of forbidden desire. Drawn to that thrill, she began repeatedly cheating with other regulars, experiencing one new pleasure after another that she'd never known before. The most shocking discovery was dirty talk. Once she realized how deeply aroused she became from filthy words, she found ordinary sex no longer satisfying. Since then, she's craved deeper, more intense pleasures. That longing ultimately drove her into the arms of a professional, as this mature big-titted wife set out to experience the ultimate sexual encounter.
