A plain-looking bespectacled married woman reveals a slender, sexy body once she undresses. I've been keeping her as a secret lover, inviting her to my apartment during weekday afternoons. Though she lives in a luxury condominium, she happily comes to my modest apartment with worn tatami mats. She's obsessed with my 20cm long dick, always responding with incredibly erotic reactions during sex. Just as I started growing bored and considered ending our affair, today's encounter changed my mind completely. During sex, she became intensely aroused while talking to her husband on the phone, making this session the hottest we've ever had. I've become addicted to having sex with her while she's on the phone with her husband, and now I want to continue this relationship for the foreseeable future.
