After a long day at work, I found myself alone with my stepsister in the house. The heat of the room and our close proximity led to a simmering desire between us. As I moved in, her plump ass couldn't help but invite my attention. I took full advantage, grabbing onto it and forcing her to bend over. The sight of her perfect curves had me craving more. Unzipping my pants, I let her take my throbbing cock in hand, before eagerly devouring it with her mouth. The excitement was palpable as she continued to service me, her tongue working wonders on my shaft. Finally, I couldn't hold back any longer. I plunged into her, our bodies moving in perfect rhythm. The intense pounding left her moaning in ecstasy, her big ass bouncing with each thrust. I took her from behind, my hands exploring her body as I drove my hard cock into her. The climax was explosive, my hot load filling her up. A sight only she and I could enjoy.
