It was a pleasant spring evening when I found myself alone with my stepsister. We were enjoying the warm weather on the patio when the conversation turned to more intimate topics. I couldn't help but notice the way her body was shaped, and how her natural tits were perfectly formed. Her nipples were already hard, and I couldn't resist the urge to touch her. She didn't object, and soon we were both lost in the moment. Her moans filled the air as I rubbed her pussy through her shorts, and soon she was begging for more. I gave her what she wanted, fucking her hard and rough. She was screaming in pleasure, her body writhing beneath me. I could feel her tight pussy clenching around my cock, and it was driving me wild. I came hard, filling her with my hot load, and we both knew that this was just the beginning of our new relationship.
