For several years since my father-in-law passed away, I hadn't set foot in my wife's family home, but this time I returned for her high school reunion. After arriving, I went to take a shower but realized I had run out of body soap. I asked my wife to bring me a refill and waited as usual—only to see the door open and an unexpected figure appear: my mother-in-law. Smiling warmly, she brought in a new bottle of soap and offered to wash my back. Though I initially hesitated and wanted to refuse, her gentle yet assertive demeanor convinced me to accept. She then suggested washing my front as well. I became erect on the spot and felt embarrassed, but she said, "You're not doing this with my daughter, are you?" and added, "If you'd like, I don't mind." Before I knew it, I had replied, "Yes."
