My step-sister shows me her intimate areas in a steamy lesson

I've always been a fan of voluptuous women, and my step-sister is the epitome of that. She's got the perfect curves, with big, luscious boobs and a butt that won't quit. When I stumbled across her in her bedroom, she was in the midst of her workout, and I couldn't resist the urge to join her. As I started to instruct her on how to lift, the sight of her bending over ignited a different kind of desire in me. I found myself unable to resist the allure of her body, and before I knew it, I was plunging my throbbing member into her. The sight of her round, firm ass bouncing as I pounded her from behind was enough to drive any man wild. The climax was explosive, with my hot load filling her pussy. It was a lesson in fitness, but one that left us both breathless and satisfied.
