Mommy Gia calls her step-son into her bedroom to discuss what time they need to leave the next morning for his tutor lesson. As he is standing in front of her she notices he has an erection...and this isn't the first time. It is happening more and more. She tells him this can't continue to happen, even thought she knows he is turned on by her because of his constant "red rocket" when he is around her. She tells him to get down and sniff her panty covered crotch and then turns around so he can have access to her ass. She then has him hump her leg to help alleviate his erection. That doesn't quite do the trick though, so she decides she needs to take more severe measures. She gets out a chastity device one of her former lovers who left it in her night stand. She explains that he will have to be locked up in chastity from now on until he learns to behave, and if he does, she will let him out...and even allow him to sniffer her crotch, ass and hump her leg again.
