I massage my stepsister's breasts and give her oral pleasure

I've always had a thing for my stepsister. She's a hot 18-year-old redhead with a body that never fails to get me going. One day, I decided to give her a massage, and things quickly took a turn for the erotic. As I was massaging her back, my hand accidentally brushed against one of her perky nipples. That was all it took to set off a chain of events leading to us in bed, where I found myself pleasuring her with my tongue. She moaned in ecstasy as I worked on her, and soon, she was ready for more. I plunged my throbbing cock into her, and she reveled in every thrust. Her petite body writhing in pleasure as I gave her the hard pounding she craved. The sight of her glistening pussy and the way she came multiple times left me breathless. It was a wild ride, but we both knew there was more to come.
