Je baise ma petite demi-sœur

I was jerking off to a hot men's magazine when my little stepsister came into my room. I tried to hide it, but it was too late. She asked me why I was doing it and I told her that I don't have a GF to fuck and I need to jerk off. So, she decided to help me. I knew it is only a one-time thing, so I had to fuck her hard and creampied her sweet pussy.
