I'm watching my stepsis study her college work when I can't resist pleasuring myself. She catches me, and things heat up as she gives me a deepthroat before riding my cock hard.
I'm not much of a prude, but my stepsister is off-limits. However, when she's busy with her coursework, I can't resist the temptation to pleasure myself while observing her. It's a dirty, perverted habit, but one that I can't help indulging in. As I stroke my hard cock, I catch her glancing at me, her eyes widening in surprise and maybe even a hint of arousal. This unexpected reaction from her only fuels my desire, and I decide to take things a step further. I approach her, my big cock already throbbing with anticipation. She's taken aback at first, but then she gives in to her own desires, taking me into her mouth with a deep, passionate blowjob. The hardcore action continues as she rides me like a true cowgirl, her big ass bouncing up and down with every thrust. It's a wild, dirty ride, but one that we both thoroughly enjoy.
