"How do you know my-" Zoe began to ask, only for the anthropomorphic hyena to let out a trademark cackle. In that moment, Zoe managed to get a good look at her; about six feet tall with the physique of an amazon, arms and legs sporting thick muscles. Large round breasts larger than Zoe's head bounced on her chest, and down between her thick thighs... a long, girthy cock. It was currently limp, which made Zoe wonder how big it would get when erect... She had to shake herself off and wipe the drool from her lip, trying to compose herself as the hyena's laughing slowed.
"Oh, come on, girl! Don't tell me you don't recognize me, yeah?" Zoe squinted, focusing more on the fine details of this tall, big dicked anthro, her eyes going wide as she recognized the fur pattern.
"Hilda?"
"Ding ding ding! We have a winner folks! Knew a smart girl like you would catch on quick!" Zoe found herself pressed against the hyena's strong body as Hilda pulled her close with one arm, walking with her. "Anyway yeah, what are you doing here this late, girl? Thought you were one of those up tight types that never broke the zoo's rules~?" she teased the smaller woman, giving a toothy grin.
"I-I forgot my- Wait, how do you know all of this?"
"Well, we're pretty dumb during the day, buuut we can pick up some things that we remember when we take on these awesome forms at night. And since you spent a lot of time around us, I'd say I got to know you pretty well girl. Oh, and don't think I didn't notice you staring at my girl dick all those times~..."
Zoe gulped and blushed, ashamed to have her fascination with the female hyena's psuedopenis brought up. She wanted to come up with some excuse, when another part of what Hilda said struck her. "Wait, you said we? So it's not just you?"
"Ah, no, whole zoo's got some kinda magic that makes every animal turn into a sexy lady at night. Gives us a few other tricks too, buuut I'll save those for a surprise for later I guess! Oh, and I know you're gonna ask, so lemme nip it in the bud and say no, I dunno how it works or why it happens. No one does. And we're not really questioning a good thing, you know?"
Zoe just meekly nodded, realizing that Hilda had taken her to the hyena enclosure. There, sitting on the ground patiently, were the two other hyenas from the zoo, Harry and Huey. Of course, those were just the names she called them in private... and judging from how Hilda was going by it, it seemed the names stuck with them. The two males had changed into... interesting forms. They were clearly feminine like Hilda, but had wildly different builds: they had small, perky breasts; incredibly wide hips with fat asses and thick thighs; no muscle mass at all; and tiny cocks above wet, presenting pussies that were begging for a pounding.
"Mistress is back!"
"Yay! Mistress, bitch needs- hold up." Both had started squealing submissively, but stopped upon noticing Zoe, as though breaking character. "Is that the zookeeper? The one who has the crush on you? The one you talked about wanting to-"
"Bitch!" The offending hyenas yelped as Hilda barked angrily at them. "What did I say about talking?"
"... either sing your praise, suck your dick, or keep our mouths shut?" he meekly replied.
"That's right! Now shut up and wait until I say it's time to fuck. I'm showing our favorite keeper how things work around here!"
Zoe was stunned. This was all so much. Animals becoming like people, but sexier. Magic being real. Her favorite animals walking and talking. The smell of sex musk lingering in the air. It was all so weird...
And what worried her was that she absolutely loved it deep down, as much as she wanted to deny it. She'd long had a perverse imagination, and now it was like it was leaking out of the place in her subconscious she tried to keep it buried. So focused on this internal conflict was she that Zoe didn't notice what Hilda was doing until it was too late.
