Starting a family with your own step-Mommy

My grown boy has moved out and my much older husband doesnt want to get me pregnant again and my marriage fell apart so I end up moving in with my boy I always thought he was handsome and one day I watch him in the shower and I am shocked at how HUGE his cock is and I overhear him moaning and stroking to me and see him shooting huge cumshots on the shower curtain. It is then when I decide I must have him and sneak into his room the next night, slipping under sheets to suck his massive cock, marveling at the size and how long he is I suck him and he soon wakes up , shocked at what is happening and I quickly apologize and confess I desire him and he responds with a confession how he has always desired his hot step-Mommy We soon both start going at it hot and heavy, lots of dirty taboo talk and lots of talk about how he may be too huge for me and his size...especially after I ask him how big he is (measuring him) and he tells me it is 11 inches long. I try and take him straddling him, with his cock up against my belly showing how deep he would be inside me. Work him deep in me, telling him over and over how big and how deep he is inside me. I fuck my boy cowgirl and reverse cowgirl and at the end he pulls out and shoots a massive thick white load all over my body and face. I am so shocked by the amount of cum it starts putting an idea in my head...an idea about a getting pregnant. After weeks more of sex with my boy, we both grow even closer, with me sharing his bed now each night and my own boy using my body every day, sometimes more than once a day and being covered in his thick seed... I beg him one night not to pull out this time. He tells me that it is too risky.. that he could get me pregnant! And I tell him that I know that its risky.. but this is what I want! “Will you do this for me? I have fallen in love with my own boy and now i want you to be the step-daddy of my boy!" "please, give step-mommy another boy. It can be our secret or we can move away and live as a couple.. but i want only you to be the step-daddy of my future boy, only you" He soon agrees and agressively fucks me deeper than he ever has, so hard I cant take him “Yes, you are my man now.. I will take every inch of your big cock inside of me, everynight.. This excites me too.. I let him bottom out in my little pussy, now resized by my boy to take his 11 inch cock in my depths ...to breed his own step-Mommy He fucks me over and over each night, cumming deep in me with huge cumshots. and I scream and cum and finally become pregnant.. Now, I am going to start a family with my own boy!
