Dominating and fucking my big booty stepsister while she's tied up

I've always had a thing for my stepsister's voluptuous curves and luscious booty. One day, I decided to take things to the next level and tie her up, blindfolding her to heighten the sensations. As I undressed her, revealing her ample bosom, I couldn't resist the urge to play with her perky nipples. With her bound and at my mercy, I took out my throbbing cock and guided it to her moist opening, fucking her with wild abandon. The sight of her big ass bouncing as I pounded her was enough to make me shoot all over her beautiful face. But I wasn't done yet. I continued to dominate her, using my fingers to penetrate her tight asshole while her pussy still throbbed from my previous assault. The pleasure was insatiable, and the power I held over her was intoxicating. This was just the beginning of our kinky exploration.
