Rui Shido is an up-and-coming gravure idol known for her serious and reserved personality, with no intention of dating anyone—a policy encouraged by her agency. She herself had little interest in sex, and even after becoming a gravure idol, she abstained from sexual activity for over a year, focusing solely on achieving fame. However, one day while riding a train to a photoshoot location, she became the victim of a molester. After that incident, her suppressed desires gradually began to awaken. As part of her job, she was constantly required to wear revealing outfits that emphasized her large breasts, and the effect this had on her body became impossible to ignore. As her own hidden urges began to align with the molester's intentions, her most extreme and uninhibited side started to fully emerge.
