A set meal restaurant run by a busty mother and daughter is a popular spot frequently visited by staff members. Both women are beautiful and well-endowed, drawing significant attention. The shop gained fame for its unique "oyakodon sex" theme, attracting even adult film actors who became regular visitors. Staff and actors visit together, and after lunchtime, the store empties out, allowing for deeper interactions. On their second visit, an opportunity arises—when the mother returns home, the staff are left alone with the daughter helping at the shop. After successfully seducing her, the daughter invites them to her room for sex. In the daughter's room, they enjoy her firm, large breasts and engage in intense intercourse. Returning near closing time, only the mother remains at the store. Drinking together, their flirtation turns serious, leading to passionate, squirting sex right in the shop as her large breasts bounce with each movement.
