JOHS-029 - Young Wife Blackmailed: Uncle's Secret Intercourse While Hubby's Away

The content felt familiar, so I looked it up and found it's the exact same story as the Miho Tsuno-starring film 'A female body that feels pleasure even with someone other than her husband, and her legs start to spread'.

It depicts sex with a man she doesn't want, but it doesn't end with her falling for him either. If you skip the drama and only watch the erotic scenes, I don't think you'll find it very interesting.
