It is your first day back from university and you walk into your house and your ex-girlfriend is just sitting there. You have no clue why she is here, you two broke up over text awhile ago. This isn’t making sense. She suddenly reveals that she is actually going to be living with you. You are so confused. Katherine explains to you that a while ago, she walked in on your step-dad taking a shower. She saw his extra large rock hard cock and couldn’t resist. She cheated on you with your own step-dad. You can’t believe any of this! She never gave you a reason for the break up and you moved away, but you had such a hard time letting go of the relationship. She then reveals that she is actually now married to your step-dad, which makes her your new step-mommy. You are so angry. Your new step-mommy says that you need to establish some clear boundaries going forward. You can no longer fantasize about her, you can no longer masturbate, and you can no longer watch any porn! She is not your boss, and this is ridiculous. The more you protest this change, the angrier she gets. Your new step-mommy surprises you with a new gift. It is a chastity cage. You will be wearing this all the time from now on, to make sure that you follow her rules. Katherine then goes into detail about why she cheated with your step-dad. His cock is just soooo big she couldn’t contain herself. She will let him fuck her wherever he pleases. You’ll just have to listen to your ex girlfriend moan for your step-father’s gigantic cock. She finds you to be pathetic, and your cock could never ever compare to your step-dad’s. While she is explaining this you are secretly getting a boner in your pants. You try to hide it, and you pretend to be angry, but now this is all actually turning you on. Enough is enough and your new step-mommy has decided you don’t know how to listen so you will be getting an actual punishment. She has you pull down your pants and she makes fun of you. The fact that you got hard to her describing having sex with your step-father is hilarious to her. But, she says you are absolutely not supposed to fantasize about your new step-mommy. She bends you over her knee and begins spanking you with her hand. Your bottom turns red. Still, your cock remains hard. She then spanks you with a belt and a wooden hair brush. Katherine makes you repeat embarrassing horrible phrases, like how small your cock is. The spanking is finished once you have gone soft. She takes apart the chastity cage and puts it on you. Now you must behave for your new step-mommy, and be a good boy for her.
