You were so caught up in the conversation, it didn't even dawn on you as she said it. Tonya, or whatever influence was at work, had already changed you from male to female. And then it hits you.
"Just noticing the first change?" Tonya asked.
"OHMYGODOHMYGODOHMYGOD!" You're virtually dancing, this feels so good. Your voice is like a stage whisper, still yours, and hard to know yet that it's gotten higher. "I'm a girl! I'm all girl! This is incredible!"
"Some things we can do without a lot of complication. Inclduing giving you back that special and exceptional part you wanted as part of the change. Mastery of gender is the easy part for us. A little science, a little magic. And we've had a lot of practice to make this right for everyone who wants it."
You feel a penis grow back in above your new clitoris. Quickly, it pushes up past your clothing, a massively long, erect shaft.
"You'll want to get out of those clothes before they get too confining."
You're loving every split second of the sensations, and rush to remove all your clothes. Just as you finish, your balls drop back in, but somewhat larger than before. And another set of long, feminine arms forms at the same time under your original pair, as you feel your upper torso elongate slightly to accommodate enhanced musculature and the added space needed.
"Let's give you a moment here to see if this feels right. You didn't want any more breasts while we're at this, did you?"
Literally catching your breath and overwhelmed with joy, your four hands explore your breasts and new penis. Four hands. Touching. You've never had four hands touching, let alone able to touch all at once, your penis before. And it just makes you so much more excited. "For now, this seems like we have the right number of arms and breasts. This feels incredible!"
"OK, then," Tonya says, "let's finish the changes to you, and then maybe a surprise."
Surprise? This feels too good, and you just have to go through with it, but that word concerns you. What could she possibly mean? You've already accomplished in the first few minutes of an office visit what you expected could really take months, and she's about to finish. You're thinking, and worrying, and then the final changes hit suddenly and powerfully. In instants, your legs split, then change shape, and the area between old and new sets of legs suddenly grows. And grows. To do this, it seems your body almost melts below the waist for a moment, and the sensation hits the pleasure centers of your brain like an orgasmic tidal wave like nothing you could even imagine. It's wired directly into your being, and you feel every bit of it, gaining control as the changes are made and established. While it continues, it's like the most powerful addictive drug. All of you craves it and wants more in ways you can't completely grasp. And then it stops. Like a car hitting a brick wall suddenly placed in the middle of the road. Too suddenly. And you miss it. And standing next to you is Tonya, now also nude, and below her face, she's nearly your twin, down to the four arms, gorgeous breasts, and centauress body with that wonderful something extra you kept for your new self, just as turned on, it seems, as you are.
"I'd been pondering a change for ages. When you came in with this inspired combination, I wanted it, too. I'd tried some other changes, and they didn't quite fit. I've always stayed female, but that didn't quite fit, even though I didn't want to be a male. Something was just missing. This is perfect. And I also know the emotional impact of the change. Wonderful, and for a little while, it feels like when they're over you're missing your best friend. It helps to have someone to share the experience with. In this case, I'm hoping you'll share as much as you want." Tonya, just standing there breathing, was the most attractive woman you've ever seen. Anything and everything just offered for the taking. Or the asking. It's just overwhelming to have everything all at once, and you're feeling how much your life just changed in the past few minutes.
"I hadn't really had the chance to think beyond the change. I wanted and needed it so badly for so long. I hoped. I mean, I really hoped I...I..." You try to finish, but even without Tonya's alluring body right next to you, you'd have been at a loss for words right now. And you're so horny! Some of this...most of this...is going to be totally new to you...to both of you. Words seem so necessary and still so in the way right now. You said you wanted to be a girl and were still attracted to girls, and Tonya is stepping up so close you can feel her body radiating heat, hoping you'll step in closer and take hold of her, so close you're shaking just trying to wait another moment without touching, being drawn to touch her and do so much more than just touch her. It's so easy to give in, and yet this has possibilities and you want to give this a chance to last.
