Three female college students end up staying at a hot spring inn during their graduation trip. Thinking it was an ordinary inn, they were spending their time normally, but when they tried to enter the open-air bath, they were suddenly raped by the employees! However, upon regaining consciousness, they found that time had reverted to before bathing… Only the girl who was subjected to internal ejaculation vaguely remembered the experience. Then, as she was in the indoor bath again, she was raped once more and returned to the original guest room… Thus, they repeatedly experienced the same time, being raped for life…
