You are my step-son and you overheard an argument I had while speaking with your step-dad on the phone. I had been waiting for him to return but he didn't show- this was a big deal because I am fertile today and he was supposed to get me pregnant. I decide to go to bed but then my blanket gets pulled off me and you come behind me in the bed. I think it's your step-dad and since I'm still mad I don't look back- you come inside me from behind but then I realize it feels different and I turn around and see it's you. I tell you we can't do this but you know I'm horny and desperate for a baby. You tell me how you've been fantasizing about me and how your friends have said they want to fuck me too. Now you are jealous and you want me all to yourself. It makes me feel good and I admit I want you too. I tell you to fuck me like a husband would, then I want to taste you so I lick our juices off your dick but I want more so I come on top of you to drain your cock again. Now I am addicted to your dick- are you sure this is what you want?
