A cheerful adult performer plays a serious student who dislikes studying, notices boys staring at her breasts, and comes from a struggling home. She suppresses her wish to become a big sister and have a younger brother—until hypnosis rewrites her reality. She becomes convinced that a 45-year-old unemployed man has always been her little brother, secretly meets him despite her father's anger, and accepts the fantasy completely. He uses the implanted sibling bond and overwhelming squirting pleasure to place her under total control.
