Following her terrible breakup with her lover, Danny's step-sister Rachel James is welcomed into the home of married couple Danny Mountain and Mercedes Carrera. They watch Rachel use sexual terms to win a game of scrabble that they find highly "deviant. " Unaware that their guest has ulterior intentions to moisten her brother's massive cock with her pussy, Mercedes and Danny decide to call it a night and go to bed. As Rachel tiptoes down the hallway, she hears her brother's bedroom groaning. Taking a quick peek, she discovers Mercedes riding Danny erratically. She starts massaging her pussy through her panties, eager as she watches the married couple screw each other. Rachel moves as Mercedes leaves the bedroom to answer a call from work. Danny is sleeping with his mask on, so Rachel slips inside the bedroom while he's still asleep, not realizing that his sister is going to be riding his erect cock. To keep things unexpected, Rachel whispers in his ear while wearing the napping mask. As Rachel takes down his panties and begins sucking on his stiff cock, Danny believes they are going to have another round with his spouse. With a sigh of satisfaction, he demands that she ride his large, lengthy cock. His slutty sister clings to his legs and pounds his hard meat, obedient to his hard cock that stretches her tight pussy. Danny watches what appears to be his wife fucking him, only to be duped by the blonde vixen! Despite this, Danny finds it impossible to refuse what has already begun!
