Escaping the daily grind of their homes, married women Kaoru and Satsuki embark on a solo hot spring trip. While enjoying themselves together, they are approached by a group of charlatans and end up drinking with them. Upon waking up intoxicated, she finds her mature body being toyed with and penetrated. Her body, forcibly returned to the woman who offered no resistance, is subjected to this in her room and the bathhouse. She is filled with semen all day long, continuing to be impregnated and debased.
