Original title: 大人になった姪っ子に妊娠OK淫語と大胆パンチラで誘惑され続けたボク…

The story follows a man who is reunited with his niece now that she has reached adulthood. The dynamic quickly shifts from familial to predatory as the niece begins a relentless campaign of seduction. Using a combination of "panty flashes," aggressive lewd talk (ingo), and the shocking offer of unprotected sex with the intent to conceive, she pushes her uncle toward a moral breaking point. The film focuses on the psychological tension of the taboo and the uncle's eventual surrender to her advances.
