MIAD-911 Living together in incest like a maid who does everything, little sister Aoi Rena

One day, out of the blue, my little sister who loves me barged into my apartment where I live alone and declared that she's going to live with me! She takes care of me like a housekeeper, doing the cooking, laundry, and cleaning, and on top of that, she acts like my girlfriend, cuddling up to me! When she hugs me and tries to kiss me, my reason shatters! Even though I know it's wrong for siblings to have such a relationship, that only makes it more exciting! My life is in full bloom with this incestuous, loving cohabitation!
