Stepsister's big ass gets covered in cum after I watch her pleasure herself

After stumbling upon my stepsister's private stash of porn, I couldn't help but be drawn to her voluptuous curves and alluring assets. That night, I decided to secretly observe her as I knew she had a habit of self-pleasuring. To my surprise, she caught me and instead of getting upset, she decided to put on a show for me. She unleashed her inner slut, flaunting her luscious big tits and tantalizing big ass. As she began to play with herself, her wet pussy squirted all over her pillow, a sight that left me utterly mesmerized. But the real climax came when she offered her ass up for me to fuck. After a wild session of assfucking, she spread out on her back, and I covered her perfect big ass with my hot load. It was a sight to behold, and I knew right then and there that this was just the beginning of our forbidden escapades.
