I gave my young busty stepmother to my classmate

My life is just a boring life that involves traveling back and forth between my home where I live with my silent father and a school where I have no place to go. A rosy event occurred in such a gray everyday life. My father remarried to Julia, a young, beautiful, busty girl, and I got a new mother. It was the best surprise for me as an adolescent, but life wasn't easy... and I learned that Julia was having an affair. I was hurt, and I offered my stepmother to a classmate who was bullied me in fear...
