One day, my sister, who loves me, suddenly came to the apartment where I live alone and declared that she wanted to live with me! She took care of me, who is a messy person, by cooking, washing, and cleaning like a housekeeper, and on top of that, she was like a girlfriend to me! When she hugged me and kissed me, my reason collapsed! Although I knew that it was wrong to have a relationship between brother and sister, it actually made me excited! My life was full of roses as we lived together in a very pleasant incestuous love-love relationship!
