So, uh, welcome to the "Strict Mature Content" portion of the story.
I'm not going to lie, this scene is one of the reasons I wrote this story. Out of all the sex-shifting TG fiction I've read, I don't know that I've ever seen any where there's a shift during sex, and I wanted to explore what that might read like.
This scene is also the impetus for the dream chapter and the gender discussion last chapter - I really wanted to make sure it was clear that both Quinn and Celia were at peace with Quinn's new dual-gender nature before they got sexy with it. I wanted this to be a comfortable story more than an awkward one.
