Sakura Asada is a 28-year-old housewife living in Tokyo with two children. To earn money for household expenses, she secretly works a part-time job involving lactation. Hiding it from her useless husband and claiming she needs child support, Sakura agrees to participate—but in truth, she's a shameless, lustful married mother. Pretending she must secure milk for her children, she freely milks her breasts and dives into depraved acts without restraint. Reaching climax after climax, she murmurs, "Maybe I really am a pervert..." as her desire refuses to subside. Even while producing breast milk, she squirts copious amounts of female ejaculate, revealing the true nature of a horny, aroused mother. Lost in pleasure, forgetting her husband and children, her sight—spraying milk and chasing ecstasy—leaves viewers completely mesmerized.
