Ask her about going through the Process.

"Could you tell me about how you went through the Process?" you ask out of curiosity.

She brightens up. "Sure. I'd love to," Belinda says.

"As you probably know or have figured out, Ethan and I were identical twin brothers and I was named Brian. Neither of us were particularly outgoing or masculine boys. Daddy is a rather overpowering figure, as you may have noticed, and I think we both just sort of shrunk in his shadow. You know?"

You nod. That would be very easy to believe.

"So I'd just gone through puberty a few years ago and figured out how to jack off and was learning how to enjoy all of that. I grew up knowing about the Process, of course, but never figured it would apply to me and nobody in my class was going through it yet, though I did know a few older boys who had turned into girls. At about that time, I was jacking off a few times a day, mostly dreaming about fucking girls. I knew about blowjobs and I was really flexible and I was soon trying to figure out how to suck my own cock, figuring that would feel fantastic. I could get my head down pretty far, but I wasn't that big down there so I could really just fit the head in and then I'd stroke myself off and come in my own mouth. That was really exciting so I was soon swallowing a couple of my own loads every day and my fantasies started turning to servicing other men sexually. You know, mostly cocksucking, but I did start some anal play and soon graduated to fantasies about getting sodomized by big, manly men like my father. I still fantasized about women as well so I suppose I was bisexual then as I still am.

"One day, I'm fantasizing about being spit-roasted by a couple of studs and I'm doubled over, with the head of my dick in my mouth. I had one hand stroking my dick and the other playing with a butt plug I had stolen from Daddy's collection when I noticed that I couldn't quite get my dick as far into my mouth as I used to be able to. I figured it was the angle, but when I was done, I measured it and it had definitely shrunk a bit. A couple of days later, I noticed I was growing breasts.

"So I went to Ethan, quite nervous and frightened, but figuring it was probably happening to him too so we could go through the Process together. I showed him my breasts, but he didn't seem to have any. We stripped off to compare dick sizes. His was already hard so I stroked myself hard to compare and his was appreciably bigger than mine, even though we were identical twins. Daddy wasn't lying about those pheromones that get pumped out in the Process. Ethan was crazy horny so he ended up being the first dick I sucked and then he took my anal virginity. We told Daddy what was happening and he examined me and the Process went pretty fast after that. Ethan fucked me silly throughout it."
