A perverted mother who doesn't reject her son's urination but instead happily receives it orally, absorbs it with her entire body, or directly takes it into her vagina—exhibiting abnormal behavior. Even when her son urinates inside her vagina during sex, she doesn't get angry; instead, she passionately grinds her hips in ecstasy. When stimulated like this, she experiences the strange reaction of producing a different kind of urine.
