My first time having anal sex with my provocative stepdaughter after being left alone together

My stepdaughter, a provocative blonde, surprised me in the gym. I\'d never seen her naked before. Overwhelmed by desire, I took her in a wild, hard fuck, condom-free. It was our first time, but she craved it. We both loved it, and she eagerly took every inch, even anal, until I climaxed inside her.
