When I was 19, I went on a hot spring trip with my then-boyfriend. The inn was known for its mixed bathing, but when we got there, only men were in the mixed open-air bath, so I went to the women's bath. However, I still wanted to try the spacious open-air bath, so I went to bathe around 1 AM! Of course, I invited my boyfriend, but he had drunk a lot at dinner and was dozing off, saying he would come soon. Reluctantly, I went ahead, but this was the beginning of my mistake... When I peeked into the mixed open-air bath from the women's bath, no one was there. It seemed that some women in their late twenties had just finished bathing and were changing into their yukatas. They reassured me, saying, "No one is in the mixed bath," so I went to the open-air bath with peace of mind... However, it seemed that the open-air bath could also be seen from the men's indoor bath, and suddenly two young men appeared wearing swimsuits! I had been soaking in the bath for a while and wanted to get out, but I had nothing to cover myself with. Since they were wearing swimsuits, they sat on the rocks in the open-air bath, dipping only their feet, and kept watching me. Gradually, they approached me, saying, "If it's too hot, you should get out of the water." But I didn't have anything to cover my body with. While waiting for my boyfriend to come, I ignored them, but suddenly they attacked me together. Since it was an open-air bath, they skillfully dragged me behind a rock. Even though I tried to escape, they held me down, gagged me with a towel, and tied my arms with a wet towel, making it impossible for me to resist! They made me hold onto the rock and assaulted me from behind and in front. If that was all, it would have been bad enough, but the nightmare was that despite it being late at night, some older men came into the open-air bath from the indoor bath. At first, they seemed to think a couple was fooling around and watched from a distance, but when they realized it was rape, they held me down and licked me, saying things like my breasts were small, and molested me. They filled every hole—mouth, vagina, and anus—and I was gang-raped by five men. I don't know how many times they ejaculated on my face. Even after they finished, they made me suck their limp penises, and I think I was assaulted for over two hours. When I was finally released and returned to my room, my boyfriend was passed out drunk, and I was furious. We broke up afterward. Fortunately, I didn't get pregnant, but I never want to experience such a terrifying ordeal again.
