That's probably what you're asking right now. Currently, I'm thinking around the weekend once more, since I have a free day on sunday, which is pretty neat considering I thought I'd have to go to work.
I rewrote the third chapter of the story. It now is almost twice as long and also includes a scene where RD does cute foal-like stuff while only being semi-aware of it. Also changed some things to the encounter at the end, such as a more obvious regression of RD's mind and a bit more details on what she thinks about her diaper's state over the course of the chapter.
