Sakura Okano, a married woman from a farming family, takes on the challenge of losing a virgin for the first time in her fourth AV experience. Normally, her husband or a male actor takes the lead in sex, but she is hesitant, but she gently teaches him from start to finish, and enjoys it with him, straddling him in the cowgirl position and successfully graduating from virginity. Even after he ejaculates once, she continues to respond to his dick, leading him to multiple ejaculations in a caring first experience.
