Hey there,
Just thought I'd plug my most recent story.
The Facility: CYOA Part 1
The Facility: CYOA Part 2
It's a more freeform "choose your own adventure" where I write up a prompt and ask where/what the protagonist does next. Most votes in one area (or the one I like the most : P) gets written up next! So far, it looks like it's leaning toward the TG side of things, hence my plug here. Put in your votes to push it along!
The MtF process is just starting by the second part.
Also, I've got another TG story in my gallery (Though it involves both MtF as well as anthro tf's as well):
Lover's Dream
Enjoy!
