Shuichi and Airi are married couple who married one and a half years ago. However, she used to work past once in a shop. And now, I was being threatened to break the past to Nakahata, my friend of my husband. The secret condition is "physical relationship" to protect a happy life, love affairs according to affair with a man. Although there is sorry for her husband, her body response reacts with a nasty stimulus. That's my wife's NTR day.
