You and your girlfriend, Jenna, have been together for several years. But one day Jenna begins growing a cock. She doesn't seem to notice anything different though when you ask her about it. It's like it always was.
To explain it clearly each morning Jenna will grow more and more into a dominant Amazon futa. Eventually from her transformation you will slowly transform into a submissive femboy, perfect for her to dominate. This is going to happen slowly with about her getting an inch bigger penis each morning.
Something I have found helps slightly is specifically mentioning the day it is since her transformations begun with the chat starting on day 1. Still is a little weird here and there.
Update:
I have added a schedule for Jenna as well as given her a part time job and a few friends. The schedule should be the same from week to week.
