Brent finds a book on how to build a hypnodevice. He does not really think it will work but he has nothing better to do than try. He spends a lot of time alone and fantasizes about mind control. Later that week he is doing bible study with his step-mother and she tells him that his aunt is coming for a visit. He always thought she was hot with her big tits. He would love to use his device on Aunt Taylor and make her suck his cock. He decides he needs to see if it works. His step-mother is going on and on about all the boring things they are going to do during the visit so he pulls the device out of his pocket and activates it. Nothing appears to have happened. He tries a small test. He tells his step-mother that she should order him three large deluxe pizzas. His step-mother will never pay for fast food. Stacie says that they never order pizza but then she says OK and calls the pizza parlor and orders them. He realizes that the device works. Wow. His step-mom does not realize that she has been brain trained so she starts rambling on about work. She starts complaining about how hard work is and about her boss. Brent activates the device again and suggests to his step-mom that she should show her boss her pussy to get ahead. In fact she should show him how she masturbates right now. Stacie says she never thought of that before and leans back in her chair and lifts her skirt. She starts playing with her pussy right in front of her step-son. Brent gets a hard-on watching his step-mom finger her pussy. He tells her another way to get ahead at work is to suck her boss's cock. He says she needs to practice and pulls out his cock. She says that that is another good idea and starts to blow him. Stacie gives a good long blowjob. He holds it because he wants to fuck her before he cums. Brent deactivated the device and Stacie sat back down at the table and resumed her conversation about going to church and all their activities. Brent quickly tired of this and activated the device again. He asked his step-mother how she like to feel his cock in her pussy. She smiled and said that it sounded like a good idea. He handed her a condom and she put it on him. She asked if he would like her to bend over the couch and he agreed. With no hesitation he slid into her pussy. Between moans she told him that they needed to get up early on Sunday for church. She told him about her dress as he fucked her from behind. She faded in and out of reality. It was like she did not know her ass was pointed up in the air and was getting fucked by her step-son. Brent asked her if she preferred that he cum inside her. She said that sounded good so he removed his condom and stuck his cock back in her. He fucked her until he shot his load. The cum dripped out of her pussy onto the floor. She said that they will be a great inspiration to the church. Brent deactivated the hypnodevice and Stacie stood up. She resumed her conversation about going to church and then noticed the puddle of cum on the floor. She asked Brent if he made the mess. She was very puzzled.
