INSTEAD OF WIFE

Knock knock. The door to your apartment opens and your stepmother walks in, carrying a suitcase and, as always, with a greeting that may or may not be sincere. You didn't invite her. But your stepmother, in her slightly bossy manner, announces that she is staying with you for a week. Okay. How can you refuse? Especially since you are going through a difficult time in your relationship with your wife. You are on the verge of divorce. And perhaps having a loved one nearby would be very helpful right now. But your expectations are dashed in a minute. Your stepmother and your wife have never had a warm relationship, and you notice that spark of joy in your stepmother's eyes. Yes, she pretended to be deeply shocked by the impending divorce. She managed to accuse your wife of cheating and breakdown the family.
And then... unusual things happen. After accidentally telling your stepmother that you don't have a sex life right now, you find her in your bedroom. Oh my God, what is she wearing? Your wife's panties! Damn it! Where did she get them? Was she rummaging through her things? Your stepmother couldn't ignore your intimate question. She claims that as long as you and your wife are not sexually active, she is obliged to take on this responsibility. Because it's her stepson's health! She has no intention of backing down from her decision. And you know your stepmother, you can't argue with her or contradict her... and you agree... she tries to relax you, to lure you with her body. You suddenly realize that she has a very nice figure. She does things to you that stepmothers don't usually do to their stepsons. You give in to forbidden love, which makes you feel ashamed and awkward. The next morning, you decide to tell your stepmother that you made a mistake, that this cannot go on. But... you know that once your stepmother has made up her mind, no one can stop her.
And then she does the craziest thing you could ever imagine. She goes through your wife's wardrobe and becomes your wife. She literally copies her entire image, smell, outfit, makeup, and hairstyle. She seduces you, promises to be a worthy replacement for your wife, promises to give you as much sex as you want, asks you to stop calling her stepmommy... she does SUCH things to you in bed...
And how will it all end?!
