Shrinking Around Humanoid Pokemon!

by TGA666 on Oct 5, 2020
Fetish

Welcome to the world of humanoid Pokemon! This idea originally comes from several interactive stories from writing.com, but CHYOA has much better tools to avoid requiring 20 chapters just to choose your pokemon. You can be either a trainer, being shrunk by one of your Pokemon or a Pokemon you are trying to catch, or an average citizen in the pokemon world. Y...

*I want to try something I haven't before. I want to try to interact with comments. At certain parts of the story I plan to have the main character doing something like online chats or something of that nature. She would interact with the comments you say as if you were talking to her. Some of the things you say could influence certain changes to the main ch...

I remember what started it. I was standing in the kitchen, staring at a pile of dirty dishes, late on a Saturday morning. Little serving plates and wine glasses had been stacked haphazardly in both of the big stainless steel tubs and had spilled over onto the island's countertop, bits of food still clinging to many of them. Every bit of counter space around...

Snowball story writing

on Apr 22, 2025

If you don't know what a snowball story is, read this: https://prestoplans.com/snowball-writing-collaborative-writing-activity/ This works somewhat like Image Inspiration Chapters. However, after someone writes a chapter, someone else has to continue that story with another chapter. Try to end each chapter open-ended. Note: Stories with an asterisk * have no...

Well of Three Wishes

Sci-Fi & Fantasy

This story contains some absurd levels of growth. If mini-giantesses with huge boobs are not a thing you enjoy, this story is not for you. It also has a reality bending component, if you like simple, straightforward transformations, this is a far cry. ***** It had been billed as a mystical place as part of the Magical Ireland Tour, but as Myra and Leela lo...

Pt.6 — The Road by Paul Gerard (a pen name) ~ Part 6 of a 12-part tale, laced heavily with lesbian encounters and strange transformations. ~ A word of warning, before you even start reading: A lot of what happens in this story focuses on the rather weird fetish of Breast Expansion (BE) – from A to D, and occasionally up to and ultimately beyond the si...

"The process," Dr. Willover spoke into her lapel mike as she made minor adjustments on the computer, "while not perfected is, I believe, in the final stages of development." The doctor adjusted her glasses, peered at the display. The wire frame image of the cat reflected in her emerald eyes. Satisfied by what she saw, she continued speaking, causing the idle...
