Fumino and her husband have been married for two years. Due to her husband’s inability to find stable work, his uncle stepped in to help. The uncle secured a job for Fumino’s husband at his company, where he is the chairman, and invited the couple to live at his house for convenience. Three months later, her husband’s job seems to be going well, easing Fumino’s worries. However, their sex life has become increasingly dull and infrequent. Fumino craves passionate lovemaking, but her husband won’t even go down on her, leaving her unsatisfied. After her husband leaves for work, Fumino masturbates alone, only for the uncle to catch her in the act and learn of her situation. Secretly attracted to Fumino for a long time, the uncle seizes the opportunity, entering her room and bringing her to climax with his skilled tongue while she protests. Despite her words, the pleasure overwhelms her, and though she knows it’s wrong, her body craves more—she wants the uncle to fuck her and make her cum again with his expert tongue.
