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.
