On the first anniversary of her debut, second-year SOD publicity employee Akari Matsunaga is placed in a training program to become an SODSTAR. Despite the pressure of joining the flagship label, she takes on an all-orgy challenge: nearly 40 ejaculations, including 23 creampies and 11 facial cumshots. After facing 20 men in this grueling initiation, she leaves her office-worker identity behind and announces herself as an exclusive porn actress.
