A trio of college girls ends up staying at a hot spring inn for their graduation trip. Thinking it was just a normal inn, they were about to enter the outdoor bath when they were suddenly gang-raped by the staff! However, when they came to, time had rewound to before they even entered the bath... The only memory left was the hazy recollection of being creampied. Now, as they're in the indoor bath, they're raped again and time-leap back to their original room... And so, they're forced to relive the same time loop, enduring endless rapes.
