My husband's brother is a professional photographer who works internationally. He was going to stay with us for a week before his next job. However, my husband had to go on a business trip unexpectedly, leaving me alone at home with my brother-in-law. One day, my brother-in-law asked me if I would let him take my picture as his model. As he took my picture, I gradually became more and more aroused. As I complied with his requests for more exposure, I felt my body flush, and hidden sexual desires that I hadn't even realized I had were being exposed.
