Wife (Hiromi), who came for a model audition, appears as a lingerie fetish model. Initially, the shoot was just about showing off her underwear, but lured by sweet talk, she gradually starts posing in increasingly erotic ways. She calmly exposes her pussy by pulling down her panties, her lustful true nature becoming more and more apparent. Seeing her reactions, she confesses an interest in being trained. Ultimately, she undergoes intense vibrator torture, her erotic expressions growing more intense. The film culminates in a lewd finale with sperm injected deep into her vagina. Hiromi is a horny, impatient milf whom the protagonist met through an online dating site. She works at a factory, earning money little by little, but it's not enough to make ends meet. That's why she meets men through dating sites to earn extra cash for living expenses. Her impatient personality and love for sex amplify the increasingly erotic developments. While her face isn't particularly attractive, her body is incredibly sexy, giving her a unique appeal unlike other housewives. Milfs like her absolutely love doggystyle, and her naughty side becomes more and more evident. It's easy to understand why such a woman leads to an intensely erotic experience.
