A son-in-law yukimi

A married husband and wife who lives with four daughters and their parents. From father-in-law to the daughter and wife who is not blessed with the treasure, "what does the child make?" . It was because of the indifference of the mother-in-law and grace of the mother-in-law. The desire for the grace of Kouichi reaches the limit, and it hits the huge busty of bathing. The courtesy of Koichi, which was blown away by reason, escalated, and yugiri who was able to have the ripe body was drowned in the affair in the family.
