Haha to Ane to no Himitsu no Kazoku Kankei -Midara na Omoi ni Oboreru Kairaku | 母と姉との秘密の家族関係 ～淫らな思いに溺れる快楽～

My family consists of my parents, who are close to me, my sister and her husband, who are also close to me, I, Mayo Kotoshiba, live under one roof with them. However, after losing the job war and becoming unemployed, I was no longer able to be a part of the family reunion.

One day, my mother, worried about me, comes to visit me in my room.

Mother will do anything if it will help you get better! ‘Then help me get off then!’

I was just saying those words out of annoyance. I started to have physical relations with my mother.

Eventually, my sister found out about the relationship and ......

Why wont you stop? Its going to destroy our family. Then, why dont you take over then! Just once! Ill take her place for today! Then everything will be good again, right?

Thus began an illicit triangle under the guise of a peaceful family.
