"I'm really excited about this," you tell the scientist. You're practically bouncing in your seat while she examines you. Her handheld instrument chirps merrily as she sweeps it over your shoulders and chest. You hope that means you're in good health.
"Mhm," she nods absent-mindedly, "and what did you say you were becoming again?" she asks.
"Oh, didn't they tell you already?" you ask. "I came here so I can be a bird!"
The scientist almost drops her scanner right then and there. "Wait, a bird?!" she exclaims.
"Um, yeah, why? Is that a problem, doctor?"
"No, not at all! Just a very funny coincidence. I did another avian transformation just before I came here. But, well, it is a surprise in your case, because, well, we don't get many guys who undergo species reassignment for that, specifically."
You perk a bit, noticeably surprised that she is surprised. "Surely it can't be that uncommon, can it? I see guys walking into species reassignment centers all the time. Surely at least some of them want feathers and beaks?"
The scientist gets a real sly look on her face. "Well, some of them do, but very few of them would actually go through with it."
"Why not?" you ask.
"Well, I'm gonna be blunt here, most guys really don't wanna have to part with THAT."
She is pointing to your phallus, uncovered since you undressed for the last time ever. It suddenly occurs to you that you can't really remember ever seeing a bird with a dong before. "Where even are the male bird's penises anyway?" you finally think to ask. The scientist shrugs.
"Inside of them," she answers, "if they even have a penile organ at all. Birds release their sperm, eggs, and waste through their cloacas."
"Wait a minute. You mean I'm not gonna have a butt hole? Or, I'm only gonna a butt hole, or, um, uh, I mean I'll have--"
"Just one hole to work with down there? Yeah, that's part of what you've signed up for, so..."
You're jaw drops. You finally manage to say, "That's gonna be weird." The scientist nods.
"So... are you sure you still want to do this?"
You giggle when the asks that. "Of course I still wanna do it! I mean, I guess things are gonna be different down there, but it's not like I didn't expect some change anyway. I'm gonna have feathers! And a beak! And those cool, freaky-looking bird feet! I've been looking forward to my new body since before I was even old enough to consent to this."
The scientist smiles and waves her med-scanner over her laptop so they can sync up. Sure enough, in no time there's a diagram of you on the laptop screen, with all kinds of data that you can't read from where you're sitting. The scientist picks up her tablet so she can pull up all the details of your application. "Okay, sir," she tells you. "I can see you've finished all the legal paperwork. It says here your customized serum is already 95% synthesized. Oh, and it looks like you have specifically chosen to be a ..."
