Stepsister seduces me with her big ass while I spy on her

As a horny guy, I can't resist the allure of a hot ass. And my stepsister, who's not actually my sister, has the most tantalizing derriere. I used to spy on her whenever I had the chance, and today was no exception. I caught her bending over, showcasing her ample assets. I couldn't resist any longer and rushed to the hallway to get a better look. But to my surprise, she was facing me, revealing her big ass even more. She knew what I wanted and what I needed. She started walking towards me, her body swaying with every step. She unzipped my pants and took my cock in her mouth, sucking it hard. Then she bent over the couch, presenting her ass to me. I couldn't resist any longer and fucked her from behind, pounding her hard. She loved it, moaning in pleasure. After a wild ride, she gave me a mind-blowing blowjob before we finished in each other's mouths.
