Naive stepbrother, eager to help, lets his stepsister use his computer for her online classes. As she leans over, her tight skirt riding up, revealing her luscious ass, he can't help but notice the suggestive way she bends over. When she accidentally drops her pen, he seizes the opportunity, pulling out his throbbing cock and sliding it between her unsuspecting cheeks. Unable to resist, he plunges into her, fucking her hard and deep while she gasps in surprise and pleasure.
