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.
