Found old gore porn stories i wrote for class assignments

I found old class assignments that had been graded by teachers, that were extremely graphic and taboo. I can't believe that I actually handed them in. As an adult I feel embarrassed about it. I remember one teacher being particularly upset. He complained about it in front of the class and afterwards I apologized, but reminded him that he told us we could write about anything. I didn't break any rules and followed instructions, so often times I would still get As and Bs. But I feel bad for the teachers.
