This is the story of a Forbidden StepFamily Endeavor. It all began when step-Mom was feeling nostalgic and suggested playing some Mario Party. step-Son was winning, as usual. He decided to take his prize and leaned in for a kiss from his step-mother. Shocked at her step-son's behavior, step-Mother pulled back and tried to step away. She couldn't believe her step-son had actually kissed her like that! What's worse is how it secretly made her feel. She didn't understand this feeling welling up inside her that was so... forbidden. As step-Son came over to talk to her about it, things just became more confusing. He was so insistent that he wanted more from his step-mother. He has felt this way a long time. She couldn't understand why she wanted it too. This is just wrong! She tried to resist his advances, but her efforts were merely half hearted. Even as she told him to stop, that she didn't want him to continue, she couldn't help but go along with her step-son. Her mind fought against her body, wanting her step-son, wanting to feel him inside of her. And then it happened. As her step-son's cock entered her for the first time, she couldn't believe the things that came out her mouth. Telling her step-son to fuck her harder, she came hard on his cock. As her step-son started to cum inside of her, she realized what was happening. Despite telling him to pull out, he came deep within his step-mother, filling up her swollen pussy. The gravity of what just happened started to sink in. She just fucked her step-son, and he came inside of her! She hasn't been on birth control for 20 years! She was so ashamed she couldn't even look at him. As she sped off to collect her thoughts, she told him that she must be the worst step-son in the world, and needed some time to process. The next day, step-Mother started to have the serious conversation with her step-son, letting him know that this could never happen again. She expressed how disappointed in herself she was. That was beyond wrong, and she needed more self control. step-Son tried to reassure her. This is what he wanted. He started to touch her again, and step-Mother was stunned by how easily he made her feel weak. step-Son pushed her up against the bookshelf, and step-Mother felt that she wanted him to. As things escalated quickly, step-Mother had a startling revelation. She reminded her step-son that his step-father would be home today! How was she supposed to look her husband in the eye, knowing that she cheated on him with his step-son? She could never explain this! She made her step-son promise to keep this a secret. They could never tell anybody. Now today, after her husband got home, things became even more tense. She couldn't bring herself to be with with her husband after what just happened with her step-son. step-Son confronts her in his parent's bedroom to talk about what happened. She tells him to get out, but he refuses. She tells him they shouldn't be having these feelings, and maybe they should talk to a professional or something. Trying to lighten the mood, she wonders out loud something silly. She wonders what she'll be missing out on, something that feels good... so good. Shocked to hear herself say that out loud, she can't ignore the other powerful desires coming up for her. Why does she want to kiss him? Why does she want to feel her step-son inside of her again? Why in the hell does she hope that her step-son will actually get her pregnant? Oh, it's just too much! She doesn't want to fight it anymore! She gets closer to her step-son, the way she wants to feel him. She pushes him down on the bed and wants to hear the dirty thoughts her step-son has about his step-Mommy. As she strips out of her robe for him, she wants to hear him confess his fantasies, hear him say how he craves his step-Mommy. Her step-son has unlocked something inside of her. She can't stop thinking about sliding her step-son's hard cock deep inside of her, where he came from and where he belongs. It feels so right to have her step-son back with step-Mommy. She cums over and over on his cock, finally giving in to these forbidden desires she hasn't been able to get out of her head since this started. But this time, she knowingly wants him to cum inside of her. step-Mommy tells her step-son to fill up her pussy again. Once again completely full of his cum, she knows nothing could ever replace this feeling. There is no going back now. It's going to be step-Mommy and step-Son from now on.
