We got turned on by my stepsister's sexy thong and had intense sex

My step-sis came over to my place and as she was getting ready, my eyes were drawn to the sexy thong she was wearing. It was clear that this wasn't her sister's thong, but a sexy one that she had brought along. I couldn't help but get turned on by the sight of it and I decided to take her right then and there. We started off with some intense fucking as she bent over for me, giving me full access to her pussy. It was a sight to behold as she took it like a champ, moaning in pleasure as I ravished her. But that was just the beginning. I then decided to take her from the back, in doggystyle, which only served to heighten the intensity of our encounter. It was a wild and crazy fuck, one that I won't soon forget.
