During the Golden Week, I went on a trip with my boyfriend. We entered a family bath together and ended up staying too long, exceeding our time. The next guests entered the changing room and saw us completely naked. While having dinner, we realized that the couple who saw us earlier was sitting next to us. As we tried to finish our meal quickly, the woman from the couple, Emily, said, "I'm sorry about earlier. We entered without checking." "No, I'm sorry for overstaying our time," I replied. After this exchange, we ended up drinking together in Emily's room. Around 11 PM, Emily and her partner started kissing and gradually began undressing, leading to intimacy. As we tried to leave the room, they told us to stay. Neither my boyfriend nor I had ever watched others being intimate, so out of curiosity, we stayed. My boyfriend seemed to get excited and embraced me under the covers. Emily and her partner finished first, and surprisingly, Emily joined us under the covers. Emily was far more attractive than me, and my boyfriend started responding to her actions. While he was with me, he touched Emily's chest, and as he kissed me, Emily touched him... Emily's partner just watched. After a while, when my boyfriend focused on Emily, her partner came over and gently embraced me. When I said, "Don't," he replied, "Your boyfriend is with Emily." I looked over and saw it was true. Confused, I accepted Emily's partner. The four of us continued until dawn. After returning from the trip, I broke up with my boyfriend.
