I caught my stepbrother fucking my mattress! I knew that he always stared when I was walking around the house in my tiny underwear, and I knew he was a perv, but I didn’t know how much until he also got caught masturbating at his school! My initial idea was to complain with our stepmom, but then I realized how sad he was for not being able to handle how horny he was all the time. That’s when my stepmom had the best idea. For Christmas, we gifted him our bodies! He could do anything to us, and his wish finally came true. It was the best gift ever and he really knew what to do with it.
