I secretly pleasure my reserved stepsister as she cooks, and then I vigorously penetrate her, all concealed from our stepfathers

I've always had a soft spot for my stepsister, and I've been secretly indulging in my desires with her for quite some time now. It all started when she'd come to cook in the kitchen, and I'd find myself getting turned on by the sight of her ample assets. One day, I decided to take things to the next level and surprise her with a little treat. I positioned myself behind her, my throbbing member seeking out her eager opening. With a gasp, I plunged into her, taking her in a wild ride that left her breathless and begging for more. But I wasn't done yet. After a steamy cowgirl session, I flipped her over, ready to take her in a whole different way. And boy, did I deliver! With every thrust, she cried out in ecstasy, her big, natural tits bouncing with each powerful stroke. And when I finally reached my climax, I made sure she got every drop.
