Fumi Ayagawa is a 29-year-old mother of one who has slept with about five people, including her husband. Her sex drive is rising as she approaches 30, but she and her husband have had a dead bedroom since childbirth. Wanting to experience more, she decides to make porn. Her slender body and G-cup breasts hardly look changed by motherhood, yet they spray astonishing amounts of natural breast milk. The film explores lactation play in full, from drinking her milk to using it as shampoo.
