My sister got into a fight with her husband and came back to her parents' house.
He has been avoiding me for a long time and hasn't gotten along well, but he explicitly despised me, who is not even working and is a shut-in.
I want to have such weakness that my sister can't resist me.
I was hoping for this, but by chance I discovered an AV video on the internet in which my sister was appearing.
I finally found my sister's weakness.I took advantage of this weakness and replaced my sister with my own maid.
