Wish I noticed that you are always sad, my boy, and I never thought you would want another step-sister of yours. Of course, you know how flexible a step-mom I am, and I told you that there is a way we could fulfill that: if you impregnate your step-mom.
You know how much I love you and will do anything to make you happy. I’ve been fantasizing about having that round belly anyways, and having your sperm inside me growing, so why not, right?
Trying different positions and you cumming inside me multiple times is just amazing for your step-mom, knowing how much you’ve grown up as a man now and how much that dick of yours can grow inside me and squirt all the sperm inside me.
Your balls just never get drained OMG. I’m just always here for my boy.
