I'm Yuta. I've been married for 3 years. The long-awaited child was born. With the birth of the child, my wife was in a bad mood more often, and I couldn't find any enjoyment in my current life. One day, I reunited with my wife's mother, Yurika. Actually, my relationship with Yurika has a story behind it, and now my wife and Yurika are estranged. Memories of the past come flooding back with our reunion after 6 years... The days when we desired each other. The feelings of a mother who thinks of her daughter. The husband's conflict thinking of his wife and children. When those feelings became mixed, we made up our minds... A relationship of "sleeping with my wife's mother." The pleasure of the labia after 6 years. I was desperately seeking Yurika...
