GVG-433 When the whole family is away

A couple decided to debut their parents-in-law at the request of their mother-in-law. The reason my mother-in-law asked me to go home was because of my brother-in-law. A family is worried about their brother, who always locks himself in his room and refuses to leave the room. However, in order not to be noticed by his family, the older brother hid in the shadows and violently assaulted his brother's wife, while committing incessant lewd acts.
