You come home to find a beautiful, sexy girl in your apartment. She quickly explains that your girlfriend sent her; she even gave her the keys to your apartment. She explains, your girlfriend has sent her for some “special treatment.” She says your girlfriend still loves you and she wants you in her life, but she thinks you’re too immature and selfish to be a step-father. Your girlfriend has decided she would prefer to have you as her BB! She tells you she has very special magical powers. She can turn a man into a tiny bb, but to do this, she has to make him cum. She even tells you what's going to happen. Of course, you don’t believe her, and she tells you, "Well, then- what's the worst that could happen? You get to cum!" She assures you that you can tell her to stop at any time, but she knows you won’t stop her. Your dick immediately becomes hard, and she can see the bulge through your pants. She smiles seductively as she begins to massage the bulge, and soon, she is giving you the most pleasurable hand-job. She teases you as you get excited and you start building to a climax. She teases that soon, you’ll be a babbling, drooling bb back in diapers. She laughs and teases that you’ll look so cute in diapers. You look shocked at this comment, but she tells you not to be upset because ALL bbs wear diapers, and you are going to be a little BB! In moments, you are on the verge of cumming. She tells you it won't be long until you’re a helpless little bb, and your girlfriend is going to love being your step-mommy. She laughs because she knows you are completely in her power. "See? I told you! I knew you wouldn't be able to resist. You don't want me to stop, do you? Awww... Are you going to be a sweet little BB?" Suddenly, you have the most intense climax. You begin to shrink and your mind begins to fade. You have been transformed into a helpless, little bb. Now, it’s time to call your new step-mommy and give her the news. She happily tells your former girlfriend that you’re no longer an adult- you are just a little bb in diapers! “Well, you better get used to it! You're gonna be in diapers for a LONG time!"
