You get back from a short business trip and get a shock when you answer the door. Your girlfriend Claudia is taller – MUCH taller. She towers over you, having grown several feet while you were away. She explains that hearing you talk about how much you loved tall women made her jealous – and curious. She wanted to know if there was a way to grow herself, and after some experimenting, she found one. Would you like to be as tall as her, she asks? Or perhaps you want to be shrunk, even smaller next to your powerful Giantess girlfriend.
