Haru is a 27-year-old single mother. Behind her innocent appearance lies a stronger sexual desire than most. The first time she is invited to his home after moving beyond their casual sex relationship, her desire explodes. Late at night, after the children are asleep, they engage in intense creampie sex repeatedly in the living room and bedroom. With something she needs to protect, she shows a moment of release and a maddening desire. Each time hot semen is poured into her again and again, she transforms from a "mother" back into a "woman" and is immersed in the ultimate pleasure.
