"I want to," "No," "I want to," "I want to," "I want to," "No," "Why," "Girl's day." ...Ever since I was old enough to understand, I've never particularly thought that I was unhappy because of this environment. Making my brother ejaculate has become a daily routine for me. I don't think that my relationship with my brother is particularly unnatural, I even think that it can't be helped. However, it's about time I decided on my future. Should I leave home or go to college nearby? Should I abandon my troublesome brother, or take care of him a little longer?
