Incest-cohabiting life with a younger sister who does anything like a housekeeper

One day, my younger sister, who loves me, suddenly came to my apartment where I live alone, and announced that she would live together! He takes care of me, cooking, laundry and cleaning like a housekeeper, and in addition, he takes care of me like a sloppy woman! When I hugged him and kissed him, my rationality collapsed! Although they know that they are a sibling and are not good at it, this actually stirs up excitement! My life is rosy as I live in an incest and lovey-dovey life! !
