SAN-119 Captured by the cute and defenseless cock of my step-brother, I neglected my husband and became an unfaithful wife Miyu Inamori

One day, “Miyu” happens to encounter her brother-in-law masturbating. She was shy at first, but her original lewdness was ignited and she acted erotically against her brother-in-law. Before long, the two finally stepped into an area that should not be crossed. A comedy about two people who love playing with fire… in the end, her husband found out… maybe?
