Do all of you know "the world of the feeling of Immorality Zero?" In this world, perform SEX almost as same as a person breathing routinely glub-glub. Be working, and, in the house, everybody crosses equally at any moment, and meeting starts the inside in large quantities, and do Akume. See the habits of "the family whom there is" where it is natural what I roll up the teacher of the school of the son, the fiance of the daughter, father of the fiance today, and have sex with even nobody.
