I always have a clear view of my stepsister's thongs, her big pussy lips peeking through the fabric. Today, she's not wearing any panties, her hairless mound on full display. A tantalizing sight.

I had a clear view of my stepsister's room from my hiding spot. I could see her lounging on her bed, her luscious curves on full display. She was wearing a skimpy thong that barely covered her big ass and even bigger pussy lips. I couldn't resist the temptation to watch as she started to play with herself, her hands exploring the depths of her wet pussy. The sight of her rubbing her clit through her panties was enough to make me rock hard. I could see her juices soaking the material, making it transparent and revealing her pink flesh underneath. I was in heaven, watching her solo session, my mind filled with dirty thoughts about her. This was a fantasy come true, and I knew I had to make it a reality.
