Stepsister allows me to pleasure her through her underwear

After a heated argument with my stepsister, I found myself with a burning desire to dominate her. I decided to take control of the situation and use my powerful cock to assert my dominance. I reached down and grabbed her pussy through her underwear, surprising her with my bold move. She didn't resist, instead, she allowed me to pleasure her. I continued to tease and touch her, igniting a spark of lust between us. As I worked my magic, she became more and more aroused, her panties becoming wetter and wetter. Finally, I brought her to the edge, making her cum hard and fill my cock with her warm, sticky cum. The sight of her cumming on my cock was enough to make me shoot my load, covering her panties in a thick layer of cum. The sight of her panties, now soaked with our combined cum, was a testament to the intense pleasure we had shared.
