Not having any other place to stay at for the time being, you move back in with your step-father and stepmother.

They are letting you live at their house rent free, but your stepmother has laid out some ground rules. Mostly, be respectful and keep the house clean. Something that you have, admittedly, not been doing.
Your stepmother decides to confront you with this. It is her house, after all. Her rules should be obeyed. But, being the defiant person you are, you have broken them. And now, your stepmother, after fussing at you a bit, tells you that you are going to have to deal...

Not having any other place to stay at for the time being, you move back in with your step-father and stepmother.

They are letting you live at their house rent free, but your stepmother has laid out some ground rules. Mostly, be respectful and keep the house clean. Something that you have, admittedly, not been doing.
Your stepmother decides to confront you with this. It is her house, after all. Her rules should be obeyed. But, being the defiant person you are, you have broken them. And now, your stepmother, after fussing at you a bit, tells you that you are going to have to deal with the punishment she deems fit. And if you do not cooperate with her punishment, she will make sure you are kicked out of the house immediately.

And that punishment will be to emasculate you. To show you that you are not the big alpha man that you think you are. She will show you just how much of a common beta you are. And to do that, the first thing she will do is assert her dominance by washing out your filthy mouth with soap.

But, she won't be washing out your mouth with soap in the usual way. Instead, she grabs two dildos. Lathering up the smaller one with soap, she makes you suck on it. The soapy cock goes in and out of your mouth, in and out of your throat. The taste is horrible, but you can't deny liking the feeling of her pushing that dildo in and out of your mouth. When you become too accustomed to the smaller one she takes the other, much larger, dildo, lathers that one up and starts thrusting that one into your mouth, making you suck on the soapy, girthy cock all while teasing and mocking you and humiliating you.

Your punishment doesn't end there, though. That's only the first part.

For the second part, your stepmom is going to fuck you in the ass. She is going to really hammer in her lesson with the same cocks that she was just making you suck. And though you realize just how much you like it when she starts, another part of your punishment is that you cannot cum. You aren't even allowed to touch your achingly hard cock as your stepmother continuously pounds into your ass. And even when she is done doling out your punishment, you still won't be able to. Not until she allows it.
