Mercer watched his son walk in, the spitting image of himself when he was in high school, but it unfortunately meant he was just as much as a douche as Mercer was at his age. His daughter strode in with wet hair, a strapless bodice that made her tits pop out, and a nice tight miniskirt. His erection strained against his zipper, and barely noticed it when they got into an altercation, his son grabbing Samia's ass, and Samia yelling at him. His eyes widened as he heard about Jack trying to get Samia to fuck him, and anger flooded him.<br/><br/>His son... trying to fuck his own sister... It was disgusting. It was wrong. It was incest. But what he was truly wondering about was how she would look like naked, and ready to fuck. He took a calming breath, exhaling, and said, "Jack, step out of the room." He watched as his son stepped out of the room, shutting the door behind him, and he reached his desk lamp, shutting it off, momentarily shrouding him in darkness and from the sight of his daughter as he reached forward, and grabbed his handcuffs, keeping it tightly enclosed and hidden in his fist as he stood up from his chair, and walked around the table.<br/><br/>He passed by his still angry daughter, and his straining erection was quite obvious in his formal dress pants, and he locked the door, and just as quickly, lunged behind his daughter, grabbing her left arm by the wrist and pulling it behind her back while simultaneously slapping on the cuffs around it before he reached with his other hand to pull her remaining hand behind her back, and tightened the cuffs around both of her wrists.<br/><br/>He would then slump in an arm chair he'd placed for guests, and pulled his daughter with him, letting her rest on her stomach on his lap, and he laid his right hand on her ass, caressing the plump ass cheeks before pulling it down, and revealing a thong that barely covered anything.<br/><br/>"You've been a bitch, Samia..." he muttered... "And Daddy's going to teach you a lesson," he said.
