As evening approaches, the married women leave the shop, go shopping for dinner, and head home. Due to the prolonged economic downturn, or simply seeking sexual fulfillment, an increasing number of young wives are secretly working at brothels without their husbands' knowledge. There, they engage in extreme acts such as face-to-face tongue-kissing with clients, sucking strangers' penises, probing regular customers' anal openings with their tongues, and accepting middle-aged unfamiliar cocks. These seemingly virtuous, beautiful housewives use the skills they've acquired at work to earn daily wages, skillfully hiding their double lives. The striking contrast between their concealed desires and ordinary daily routines is what makes this work so compelling.
