A 50-year-old mature married woman, Satoko, secretly appears in an AV without her husband or children knowing. She is subjected to intense filming where her nipples are pulled relentlessly, and she is pounded with a large penis deep into her vagina to the point of breaking. The image of a woman showing her true form, which she would not show to her husband, is portrayed. Most of the married women seen normally are like cats pretending to be gentle, but it becomes clear that they want to have sex all the time.
