T. Stone is in the middle of a marathon masturbation session with the inspiration of an online video that gives him a beat to jerk off to. When his stepsister Kenzie Reeves walks in on him masturbating, she challenges him to last two minutes while watching her boyfriend fuck her. T. accepts Kenzie's challenge, then one ups her by saying he could last even if she was naked. Kenzie is game to keep escalating the bet with a sexy striptease. Once Kenzie's panties hit the ground, she caresses her small boobs and bald pussy. T. still hasn't cum, so she drops to her knees to stroke him off. Leaning forward, she puts her mouth to work as well. Even that doesn't bring T. off, so Kenzie lays on the couch and spreads her thighs so he can bury his fuck stick balls deep in her bare twat. Soon the pair is fucking at a hard fast pace that gets Kenzie moaning about her love for T's big cock. Getting on her hands and knees, Kenzie turns around so that T can bang her from behind. The porn keeps playing in the background, providing a sensual backdrop that helps T. keep up the perfect rhythm. He brings Kenzie off, and then barely pulls out of her horny sheath before exploding all over her back. Kenzie considers herself the winner since T. has not reached the end of the Cock Hero video.
