Photographer Sora and pastry chef Aya are lovers. The motive for applying for AV this time is "I want you to take a lewd record". Sora suddenly inserts her fist into Aya's vaginal opening as she makes her alone in the room where they live together and starts shooting and progresses with cunnilingus and fingering. The room is flooded by the splashing tide of Aya while she is pistoning. The story of the two who are delighted with her first fisting and want to pursue sex further turns into a story about lesbians, including themselves.
