After pregnancy and childbirth, Risako Takeuchi has entered the most erotic phase of her life. At 42, she raises a family of four with her husband and two sons—aged five and zero—yet struggles with sudden, overwhelming sexual desires. Her nipples are swollen and sensitive, growing fuller by the day; when her baby suckles, she unconsciously moans aloud. In the midst of motherhood, her body is overtaken by runaway erotic instincts. Her husband has fully embraced fatherhood, and their marital sex life has completely stopped. Yet even while fulfilling her duties as a mother, her body constantly throbs with arousal. Now, she is invited into a special moment—her body overflowing with thick, pure-white erotic milk.
