"I think we have about half an hour or so before you transform completely" said Fisher, looking nervous but trying to hide it. Why is he the nervous one? YOU are the one that won't have LUNGS anymore
" It usually is around 12 hours animal, and 12 hours anthro...thing." Fisher informed you, probably trying to calm you down. "We're still not sure what to call it"
Then you see it. WATER. You want it. You DREAD it. On the sign it says "Fish exhibit"
But who cares right? IT'S WATER!
"I think you still have 20-25 minutes. But I suggest you get used to it. You will have to hide when the humans come. But I also switch between aquariums. Just hide. That's all. And talk to the smaller fish you want. You can do that at both the animal and anthro stage. I have to go now! See you next evening!"
"OK, bye!" you say realizing you are now alone. Well not tehically. There still are a lot of small fish in the tank. They don't have any human features but they can still talk.
"OK, little guys, I promise not to eat any of you. Can I get in?" You say, not knowing if you can keep that promise. I mean, the sharks in Nemo didn't eat fish, right?
"We've had sharks here before don't worry sweety!" Said a small, yellow fish with pink stripes. Seems to be an 18 year-old girl. Or 18 years in fish years at least. Before you transformed, you were 18, so possibly that still applies now.
You get in and already feel more athletic. Your legs go side to side with your tail, one on each side, and you can easly move through the water. Your big breasts don't slow you down that much, but it still feels like you would move faster without them. Not that it matters though. They still feel good. Or at least normal. In fact, you got used to your new female fetures pretty quickly. Your genitals no longer feel like "a lack of a penis" and is more like a normal thing.
The little fish from before wich you can now identfy as being around halfway from your fingers to your elbow in length, is swimming towards you. "This is a really big tank isn't it? I'm Susie!" she says.
"Hi Susie! I'm..." What's your name? Brian yeah, but you're now a girl. You need a new one. You didn't like Brian anyway so... "Shannon" God damn it. That doesn't sound good. Quick, think! "But my friends call me Shan". That's worse but let's roll with it.
"Um...OK...Shan, are you new here?"
"Yeah, I guess"
"Let's get you a little more comfortable then"
she says as she stars simming under you. She is slowly accelarating. "Let's stop swimming." she says, clearly tired. So you stop."I see you are already growing in size, without any transformation." Yes you are. You are almost twice as big as you were before entering the tank. No transformations though. Not yet at least. "I want you to be relaxed before you become fully a shark."
She then swims right at your nipples, which for some reason got hard while you were swimming, and starts sucking on them. You would normally try to stop that, but not only does it feel good, but most fish around don't care. So you let her continue. Your nipples get even harder with that and you get out a little moan. And another one. And then you keep moaning for about a minute. Then you feel weird. Your legs are slowly shrinking, and your fingers start merging. Susie realizes this and goes down. To your genitals. She starts off by kissing the clit with her small mouth and then puts her whole head slowly into the pussy. Which makes you moan with real plesuare. Then she goes out, another moan. Then back in, and out. She repeats this over and over, and then she goes faster and faster. You moan uncontrollably, as your legs become small fins and your arms, slightly bigger fins. You want her do go deeper so you push her in. And then she does the same movements, but deeper. You can't control anything about you at this point. Then a really strong orgasm hits you. The pleasure fills your body. And makes you feel those new parts of your body even better. Your moan can be heard in the whole zoo probably, but you don't care. Susie gets out while you finish the best orgasm in your life. After that your whole body hurts for 10 whole seconds. After that you are a real shark.
"Liked it?" asks Susie with a dirty smirk.
"Loved it!" you respond.
You continue the day hiding between decorations, as people flock the zoo and watch the fish. After all people are gone, Fisher jumps in the water, being a complete otter (and completely erect for that matter), telling you to surface. He jumps out and says "Anthro meeting after you transform. Gonna be in the bear exhibit. See you there!"
After ten minutes you transform back into the human-shark combination that Fisher calls "Anthro".
