This film featured a famous actress in a brazen setting. The older sister's intention was to enter naked while her younger brother was bathing, and their first bath together in 10 years unfolded. Close-ups of the crotch and face in the bathtub were good, but I wanted more distant sex scenes. It is unfortunate, however, that many of the actresses' performances in the film are fantasy Nakadashi or Nakadashi with rubber, which seems to be a facial ejaculation NG.
