With only four hours—14,400 seconds—available because of an unexpected double booking, Waka Shiraiwa is made to cum for every last second. The relentless lineup includes gear-shifting follow-up pounding, a submissive man turning the tables, merciless orgasms while she holds her urine, and a four-person gang bang. Even when her sensitive, busty body convulses and she begs that she is already coming, the thrusts never stop. There is no surrender—only a nonstop festival of orgasms until time runs out.
