Lina, your step-mom, comes into your room while your father is at work to talk to you about your 'slip up' of referring to her as a mom and your bio-mom is really upset. She sits down next to you and rubs your chest, telling you that your bio-mom should have done better and should have loved you more. She leans over to kiss you. You are aroused, and she enjoys what she is seeing. She feeds you her nipples and takes off her clothes to enjoy your dick. She calls your bio-mom to tell her that you are now her son, and all touching and kissing belongs to your NEW mommy! She allows you to enter inside her, all while feeding her boobies and kissing you. Your dick is now her, and she chants for you to cum for mommy while riding you!
