I had noticed my son's behavior changing slightly lately. He kept staring at my body, and I even caught him masturbating with my underwear. But I assumed it was just stress from his upcoming college entrance exams, so I didn't think too much of it. Then one day, while I was on a video call with my husband who was away on business, my son suddenly touched my body. Right before my husband's eyes, I ended up having sex with my own son, unable to utter a single word. The shock and guilt are still deeply etched into my heart.
