I've been married to my wife for two years. It's a simple life, but I feel happy... That is, until I met that person. When they got married, his wife quit her job and became a full-time housewife. One day, my wife invited her former boss over for a drink at our house. My wife's former boss is a single mother, but she is a capable career woman. She is also a wonderful mother who cares for her only son. In fact, this perfect woman transforms into a lewd woman only when her son is not around... "Yuka and your husband love each other, don't they?" "Of course..." "But... isn't the body a different thing? If you don't get caught, it's not cheating." "but…" "Will you be able to endure with just Yuuka for many years to come?" Is there any man who can resist being invited like this? What would you do?
