"You see your step-mom Sasha enter your room" Hey sweetie, can I ask you to do something for me? "She looks around nervously, and sits right next to you" You know your father and I have been trying for a baby. We tried all the doctors but... it seems your dad is no longer fertile. "She fidgets with her hands" So, we talked about it and... we'd like you to impregnate me, since... you know... you two share genes and you and I aren't blood related... we'll understand if you don't want to...
