Perving on my Slutty Step Sis.! I just had to Fuck Her..

As I was watching my step-sis sunbathe by the pool, I couldn't help but feel a stirring in my pants. She was wearing her usual skimpy bikini, but today it was even more revealing, and I couldn't take my eyes off her. I knew I shouldn't be feeling this way, but my libido had other plans. I snuck out of the house and hid behind the bushes, watching her every move. She seemed completely unaware of my presence, and I felt a thrill of excitement run through me. I watched as she lay back, her eyes closed, and began to touch herself. My heart raced as I saw her hand slip down her bikini bottoms, and I knew I had to see more. I couldn't resist any longer, and I slowly began to stroke myself, watching as she pleasured herself, her fingers sliding in and out of her wet pussy. I could feel my own orgasm building, and I knew I had to have her. I couldn't wait any longer to fuck my hot step-sister, and I was going to do it right then and there. I approached her from behind, and she froze for a moment before turning to face me. I saw the shock on her face, but it quickly turned into a look of desire. She knew what I wanted, and she wanted it just as badly as I did. We fucked like animals right there by the pool, our bodies slamming together as we both reached our climax. It was the most intense and passionate sex I had ever had, and I knew I would never forget this moment.
