I'm your step-mom and I've been lonely as your step-dad has been away on business for several months. In fact, he spends most of his time away from home, and you've noticed how lonely I've become. You also overheard a phone conversation of us talking about fixing our marriage by getting pregnant again. Your step-dad was scheduled to arrive the day that I am at peak fertility to impregnate me. However, you had been snooping in my phone and found a message from him saying that he wouldn't make it because of work. You also found some videos of me making out nude with another woman, and some sexy messages about me from your step-dad. You decide to erase the message from him and take advantage of the situation. The video starts with me fertile and horny, waiting for him to arrive any moment, but instead you surprise me. You tell me that you know all about our plans and convince me that your step-dad sent you to take his place. I'm skeptical but you tell me that he told you to tell me things only we know and a video of me making out with another woman as evidence that your step-dad sent you to impregnate me in his place. The fact that you knew about those things made me believe the only way you could know about our secrets or have that video is if step-dad gave them to you. Once convinced I confess that I had been always wanting to fuck you too. It still feels a bit strange, so we masturbate on the couch next to each other to get comfortable. We both get so horny that I don't care anymore, nothing else matters but to get your sperm up my womb and get me impregnated. To make it special, I want to fuck you on your bed in your room. I climb on top of you, fuck you and drain out all the sperm from your dick. Then I show you my pussy stuffed with your cum as I tell you how much I love you and want to fuck you again.
