A story depicting the abnormal daily life of an ordinary family. A close-knit household of five: grandmother, mother, older sister, younger sister, and "me"—the grandson, son, younger brother, and older brother at the center of it all. My cock has a mind of its own. Whenever I'm bored, happy, or stressed, we always resolve things through sex in this cheerful incestuous family. This family enjoys the ultimate sex life together. They approach conception systematically and maintain strong moral principles, making them an exceptional family. A heartfelt warmth radiates from their openness to express love and their desire to hold each other close.
