This is an interactive story containing 39 chapters. Each chapter tells part of the story and (usually) ends with multiple choices. Click on a choice and you'll be lead to the next chapter in your story. When you reach a chapter that hasn't been written yet, you will have the option to write it! Don't be shy... make an addition!

Ground Rules

The story is a breast expansion (BE) story alone, so no giantess (GTS), female muscle growth (FMG), ass/butt expansion (AE/RE), weight gain (WG), inflation, transformation, or anything revealing about below-waist anatomy. Transgender and age progression I will allow into the interactive.
