I want to honestly recount an experience from long ago, one that became a summer vacation memory. That day was abnormally hot, the air thick and suffocating, like being trapped in a train with no air conditioning. I had gone to visit my aunt's house—my main reason being Tsubasa, a girl my age who lived there, whom I had feelings for. Tsubasa was bright and cheerful, someone I was deeply drawn to. I also looked forward to seeing my aunt, who had recently gone through a divorce but was still as kind and comforting as ever. However, that day, I unexpectedly witnessed my aunt harshly scolding Tsubasa. When questioned directly, Tsubasa remained completely silent. Late that night, I heard Tsubasa screaming in tears and, trembling with fear, I opened the door to the basement. There, I saw my aunt—someone who was supposed to be gentle and caring—violently raping Tsubasa. Overwhelmed by shock, I couldn't even register that I had been discovered. Then, my aunt turned to me with cold, piercing eyes and said, "You broke our promise..." before ordering me to rape Tsubasa as well. Contrary to my emotions, my body reacted instantly, arousal rising in my groin. My aunt saw it all—she saw right through me.
