A 20-year-old girl named Sakura works part-time at an izakaya. During her breaks, she deflowers virgin men, becoming instantly aroused by their big cocks. So turned on that she can't resist even during work hours, she repeatedly engages in bareback sex. Her passionate responses make him forget about climaxing, completely lost in the moment. Deeply moved by her enthusiasm, he begins planning to bring around fifty friends next time to book the place exclusively for a private party.
