My step-sister requested a massage from her step-brother, and he crossed a boundary by touching her intimate area. She unexpectedly enjoyed the experience, leading to an orgasm

In a typical household, my sister and I share a close bond, and she's always been open about her sex life with me. One day, she casually mentioned that her boyfriend was unsatisfactory in bed, leaving her craving for a more fulfilling experience. Being the good brother that I am, I offered her a hand. She took me up on it, and I gave her a professional massage, leading to an intimate moment. As I began to explore her most private areas, she surprisingly welcomed it. The sight of her wetness was too much to resist, and I found myself lost in the moment. I pleasured her with my fingers, and she reciprocated by stroking my hard cock. The sight of her sucking my dick was a sight for sore eyes, and I couldn't hold back any longer. I released my load all over her beautiful face, leaving her satisfied with the experience. It was a wild ride, but we handled it like pros.
