My husband's brother is a professional photographer who works all over the world. He decided to stay with us for a week until his next job. However, my husband had to go on a business trip suddenly, and I was left alone with my brother-in-law at home. One day, he asked me if I could take his photos as a model. As I was being photographed, I gradually became excited. As he asked me to expose myself more, I felt my body flush, and my hidden sexual proclivities that I didn't even know I had were being revealed.
