A big prank on Nanako, a beautiful wife who has been married for 5 years! I tried to verify the theory that ``Even married couples who don't have sex can get so excited if they blindfold themselves and have sex with their husbands in an AV shoot that they don't even notice.'' Due to misunderstandings between the two of us working together, we became sexless, and because we were interested in AV, we decided to shoot. Nanako has arrived. She told her older husband that she was going to appear in an AV, but he didn't seem to be against it or agree with it, and she said, ``Maybe she's lost interest in me,'' with a confused look on her face. That's no wonder; in fact, her husband is also the one behind the prank. After blindfolding Nanako, we bring in her husband and start checking her out erotically.
