Called into the staff room by my homeroom teacher, I was sternly warned that my poor attendance would prevent me from advancing to the next grade. Suddenly, I felt intense stomach pain and became desperate to use the toilet, leaving me speechless. To my shock, the teacher said, "Show me you're taking a shit." I couldn't believe what I was hearing. But when he added, "If you give in to this temptation and show me, I'll let you advance," I couldn't hold back anymore and ended up defecating in front of him. Emboldened, the teacher then went further and administered an enema. The abdominal pain became unbearable, I felt like I was dying. After such a humiliating experience, I can't even get married now, and I'm utterly ashamed.
