Rena Fukiishi is a former model who spends her days as a housewife. One day, she is suddenly begged by Yoshino, who lives next door, to be the monitor for a new lingerie collection and to model for it. Rena, who is weak to pressure, loses to Yoshino's desperate face and reluctantly agrees to do it once. On the day of the shoot, Rena remembers an indescribable feeling of pleasure when she shoots in lingerie. She had only agreed to do it once, but she accepts the offer to model again. From then on, she shoots with Yoshino alone, and the two excited people cross the line without much time passing.
