An office lady, Kido from the Product Department, has been having an affair with her 48-year-old boss since she was 20. Her boss, a perverted and obsessive man, introduced her to anal play, gradually pulling her deeper into his world. Not satisfied with just anal, when she expressed interest in trying more, he experimented on her body with enemas, anal plugs, and every other method imaginable. Through this process, she became completely immersed in his twisted desires, unable to escape. Meanwhile, Akiyama from the Administration Department also began a relationship at age 20 with a man much older than her—older than her own father—accumulating shocking experiences that surprised even herself. With a persistence more intense than her peers, she savored the thrill of something new, yet found herself unable to break free from the relationship. Though their stories are rooted in the past, the freshness they feel within keeps their allure alive.
