Replace Daddy's Cum

You were just starting to doze off when Mom comes in and wakes you up. She is scantily clad, only wearing one of Dad's shirts with the buttons undone, and she needs your help. Mom quickly explains that she and Dad just had sex, but they made a mistake. They did not take the usual precautions and now she is full of his cum. Gently, mom confesses, "The thing is, sweetheart, I don't want to have another baby with him. You are my perfect boy. I only want you." At first, you are not sure what she is getting at, but then when her hand reaches out and wraps around your cock you know exactly what she wants. "Please baby, will you help Mommy? Will you replace Daddy's cum with yours?"
