I'm under your covers going down on you, my StpSon. After a few minutes I pull the blanket back to reveal my Christmas hat, still sucking your cock. I call you StpMummys good boy and tell you that I know this is what you've always wanted. I know it's wrong but I just can't help myself, plus I have definitely caught you staring at StpMummy lots of times before. With StpDad leaving, I've started to see you as more than just my Stpson and I wanted to show you just how appreciative I am. I tell you that this is going to be the start of our special relationship and I couldn't be happier. I go back to sucking your cock, with my Santa hat still on. After a little while I tell you that StpMummy can't wait to get on top of you and feel you inside of her. "Are you ready to fuck StpMummy?" I begin to ride your cock, with lots of moaning and dirty talk about you fucking StpMummys pussy. I ride you with lots of closeups of my boobs and face as I bounce on top of you. I then decide to switch positions and you fuck me in doggystyle. I mention that I would like you to impregnate me and I feel your cock throb harder inside of me so I can tell that you're into the idea. We change to a missionary position and I begin to really go hard with the idea of you breeding me. I tell you that I want you to blow your load deep inside of StpMummys pussy. You cum inside of me and I show you all of your creampie dripping out. The video skips to 3 months later and I tell you that I have a surprise for you... I've been wearing baggy jumpers around the house a lot lately and this is why. It's our little miracle!! You got StpMummy pregnant!! I reveal my big bump and rub my belly. StpSon.... you're going to be the best StpFather, isn't this the best news ever??
