"Ohh, daddy," Sally moaned, as her legs nearly buckled. something's pushing out!"
Concerned, Jason looked over her daughter. Sure enough (and to Jason's shameful embarassment for seeing it), Sally's prepubescent vagina opened up, as what had once been her clitoris pushed its way out like some kind of worm. It bulged out, getting longer like a growing mushroom, even with its own large cap at the end.
"I..is that?" uttered Sally, in awe at her new growth.
"You've got a penis!", said Jason, who was quite in disbelief himself. It was a surreal sight seeing his little girl suddenly sprouting a long, cock fit for an adult donkey; even one bigger than his own! His own penis twitched at the sight.
Sally's member grew at a nice length, drooping downwards with a splotchy black and peach-colored pattern, and a flared head. Her labia had sealed up around the big member, and below, a large, black testicle sack dropped and dangled below her crotch. Fascinated, the donkey-girl felt her new parts as they stopped growing.
"It's so warm!", said Sally, with a grin. Holding up the flaccid member, she could feel it pulse in her hand, as she ran down its smooth, veiny surface. It looked weird, and yet it was quite pleasant to touch.
"Does yours feel like this, Daddy?", Sally asked innocently, as she stroked herself. Jason was embarrassed again, as he felt his own penis stirring.
But....no. It wasn't just stirring. Jason looked down. His cock, which was already slightly erect at the sight of Sally, was stretching longer and growing the same discoloration as Sally's, with its tip already flaring with a wide ridge. As it stretched, it bobbed upwards, with veins pulsing on its enlarging shaft, and its ballsack swelling underneath. Soon, Jason sported a donkey's cock just like his daughter's.
"Uh Sally...mine does feel the same.", Jason muttered, as he grabbed hold of his new donkeyhood. It bobbed slightly upwards, and hardened at the touch.
"Why is it doing that?", Sally asked, as her own member did the same. She definitely liked the feeling of it.
Jason gulped. "It, uh....it means you're excited, and you want to use it!"
Sally tilted her donkey ears. "You mean sex?"
Before Jason could answer, there was a magical shimmer coming from the nearby bed. On the spot where the transformation-triggering box once sat on, there was now a new object. A large, long rubber toy that resembled two donkey penises at each end, already slick with a lubricant that stained the bedsheets.
Jason and Sally stared at it. Walking over (a little awkwardly with his partial erection), Jason picked it up with his still-human hands. It was slick with a lubricant that was staining the bedsheets.
"What is it?", asked Sally, with her tail flicking.
"It's..." Jason knew what it was. But was he really going to use it? With his own young daughter?
As if the Resort itself was answering for him, a magical trance began taking hold of the pair. Sally moaned, as her donkey penis bobbed higher in the air. Jason's cock was getting engorged too. A temptation grew in both father and daughter, and also an understanding on what has to happen next. Yet only Jason could know how to initiate it.
"Alright Sally, come over here", Jason beckoned to the bed. Sally did so. Soon, the donkey pair were arranging themselves on the bed together, with Sally lying on her back, while her thick anus and testicles pointed at her daddy. Jason was positing one end of the double-ended cock toy at Sally's asshole.
"Okay, I think this shouldn't hurt, but it might be a little tight," said Jason. He wondered if his wife would've ever forgiven him for this. "Are you ready?"
Excitedly, Sally nodded. And Jason jammed the toy forward.
"OHHH!, cried Sally, as she felt it ramming into her donut, and squeezing through her insides. Jason stopped.
"Did it hurt?"
Sally shook her head. "Nuh-uh! It's just...feels good!"
With that, Jason continued sliding the double-end toy further, eliciting more delightful moans from his daughter. Once it's further in, Jason took a hand on the other end, and pointed at his own ass. Slowly, Jason slid it in too, making himself groan with delight.
Soon, father and daughter had the toy lodged in their donkey assholes, with one end sticking out. They could feel it rubbing against their insides, with Sally's end poking at her prostate, and Jason's end bumping at his. Both donkey their penises bobbed higher at the sensation, and their testicles tightened.
As if through the resort's strange magic, the phallics ends of each toy pulsed on their own inside Jason and Sally's bodies, and slowly stretched and thrusted within their rectums. All while their thick anuses stayed clamped inside.
"OHH DADDY!, Sally cried, as the toy thrusted within her donkeybutt. Jason groaned too, as the toy did the same to his. Already, both donkey-father and daughter were sweating and panting, as they laid on the bed, letting the toy do its work.
During all this, the fur from Sally and Jason's lower bodies had quickly crept up their torsoes, and even down to their arms. Their hands were changing, with their smallest fingers fusing together, and their nails growing thick and stubby, giving them strange four-fingered hands of a furry animal.
Sally eyed at her equine penis, as it bobbed higher and harder like her dad's. She rubbed it with her altered fingers, letting the shaft twitch with pleasure. But a greater temptation was coming to her. A strange, thirsty impulse...
"I want...I want to kiss it!"
Jason couldn't explain it, but he felt the same way too. His cock. His big, long juicy donkey cock...god, was this place really warping their minds into doing things like this? But how can he even reach it?
The resort seemed to give an answer. Immediately, Jason and Sally's eyes went wide, as their mouths and noses began to stretch forward, with front teeth flaring out. Their necks had thickened, and grey fur now spread onto their heads; covering the last of their human skin. Their hair vanished, with Sally's long brown ponytail and Jason's short cut disappearing into air, until darker mohawk manes sprouted in their place.
Within their asses, the double-ended dildo had somehow pulled them so close to one another, that Sally and Jason's thick anuses were almost kissing one another, while their balls and asscheeks squeezed pleasingly against each other.
Sally let her tongue out of her growing snout, and bent over; hungry for a taste of her own cock. Eventually, it made contact, and Sally immediately began lathering it like a giant lollipop. She savored its texture and taste, as a strange juice leaked out of its opening.
Jason followed suit. He craned his neck over, until his donkey snout reached his bobbing cockhead. Inhaling its musk, Jason opened his mouth and gave it a kiss; sucking it like a lover. The donkey-fied family wrapped their lips around the heads of their cocks, and licked away without a care in the world, all while their bodies abandoned most of their humanity.
"Ohh," moaned Sally, as her vocal chords grew deeper and hoarser. Her body was growing to a height more appropriate for an older teenager, with her chest bulking into male pecs, and her belly bloated with just a bit of fat.
"Mmph..." Jason grunted, as he worked hungrily on his own penis. Curiously, Jason's overall height was shrinking and thinning up, while his body took on a more youthful look, with a belly, pecs and muscles almost identical to his daughter...or perhaps, his son?
Something was bubbling up. Sally and Jason kept at tonguing themselves, not even hestitating for a moment in shame or guilt. Yes...they needed this!
"MMPH-BLB....!" Sally gripped his snout tight as her penis exploded with a warm, salty slime filling her throat. Jason did the same, as he swallowed his own load, letting it squirt through his snout. They gulped away, before letting their cocks free to spray seed into the air...
