Step-Mommy gently explains why you can't do all of the special things you used to do together. You're an old enough boy to understand why those things are wrong, and even though your physical relationship must end, it doesn't mean she loves you any less. Seeing how much the news has upset you, she offers to breastfeed you. Milk is nutritious, and there's no hard rule in the parenting handbook that dictates boys must be weaned early in life. According to her, step-mommies should never stop producing breastmilk for their beloved boys, no matter how old they get. Suckling step-mommy's breasts helps you feel closer to each other, and seems to temporarily fill the void left by the sexual relationship you once had.
Shortly after tucking you in for the night, Step-Mommy returns to your room. She refuses to spend one more night without you in her arms and has come to accept she will never be free of her taboo desires. As long as she lives, her body will always be a sanctuary for you. Just as it should be.
