I was hanging out with my stepsister, talking about nothing in particular when she suddenly started sucking my cock. I was taken aback at first, but then I realized that this was exactly what I had been craving for a long time. She was doing an amazing job, her mouth was tight and hot, and she was sucking my cock with such passion that I could hardly stand it. I could feel her tongue running all over my shaft, and every time she went deeper, my excitement only grew stronger. She was completely devoted to me, her body writhing around my cock, her hands massaging my balls. In the end, I came all over her face, right into her mouth, leaving a trail of my sticky cum all over her.
