VENU-904 1 night and 2 days Naoko Akase was left behind by her wife's older sister who suddenly came to her

Kazuya has angered his wife due to their quarrel. When I was worried about my wife who had gone back to her parents' house in a fit of rage...the wife's older sister, Naoko, came to me for advice. Kazuya, who was really at a loss because he couldn't find a way to solve the problem, completely gave in to the beautiful and caring Naoko. However, Naoko's real purpose is not to settle the quarrel between her husband and wife, but to relieve her frustration with Kazuya.
