A frenzied 24-hour film in which Takeda Yume's body is thoroughly used to its limits. Continuing nonstop, all day, with "ultra-piston sex," her robust stamina gradually reaches its limits. After repeated orgasms, her legs begin to tremble, and she collapses on the spot like a newborn fawn. Her consciousness fades, but the impact of the thrusts continues unabated. Her love juices overflow, and the dull sound of her uterus being slammed into the air. Beyond her limits, she enters a state of pure ecstasy, as if her body and soul are completely separated. This ambitious film meticulously records her breakdown.
