Waka, a chaste big-breasted mother, had a forbidden worry that she never wanted to find out about her neighbors. A motherless family with one mother and one child. His only son, who has reached the age of maturity, has recently been reluctant to explain his mother Waka's plump breasts. It has become "Hey, hey, Ken-chan..."
