Junko Arimori, a beautiful and charming 35-year-old woman. Her alluring figure, especially the glimpse of her white cleavage, makes her an attractive housewife who naturally draws the eyes of many men. Now in her 10th year of marriage, after giving birth to her 7-year-old son, her sex life has become infrequent. Feeling lonely yet continuing to suppress her emotions, she had been living in denial. Then one day, she discovered a porn magazine secretly kept by her husband and came across an advertisement inside—prompting her to finally decide to apply. Though shy and hesitant at first, as she experienced someone touching her soft, voluptuous body, her arousal gradually built up until she cried out, "It feels so good, I can't take it!" reaching a powerful climax. This long-awaited sex experience brought her immense pleasure and joy.
