True and abnormal sexual intercourse

The physical relationship between Yumi and son started about six months ago. It was fickle that I was sighed by the masturbation. Since then, it was the Ayumi who had repeatedly slaughtered incarceration with the son of zizzuru and his son, but he decided to break off the relationship, saying, 'this is the end of my son.' But it was already too late. When Yumi tells the end of the relationship, the son's attitude suddenly changes, and it gets cold to his mother. Yumi who cannot withstand such a thing oneself to oneself.
