#1 of The Wild River

Given the low return of effort-to-reward for the choose-your-own-adventure porny game that I was occasionally adding new scenes to, I've decided instead to pull those scenes out and turn it into the escapades of an otter family in a sci-fi adult-themed water park. Does it make sense? No! Does that matter? Not at all! Is it hot? It is to me! In my continuing exploration of my own fantasies, have chapter one, where our protagonist picks the body he'd like to use for all his upcoming fun!


The two suns of the pleasure planet Eta Ordinae Prime were just cresting the horizon as my family and I passed through the entry gates to the Wild River. Excited squeaking filled the air as anticipation melted into the thrill of actually finally being here. It'd only started to sink in: I was inside. The entirety of Wild River lay ahead of us, ours for the conquering.

"Fun! Thrills! And More! (Adults Only)" The Nebula Observer rated Wild River the best adult-themed water park of the best adult-themed planet in the best pleasure system this side of the Andromeda galaxy. It'd taken a whole year's worth of luxury credits and a null-space jump of more than seventy thousand light years to get here, but now that I was here, it felt like it'd all been worth it.

My brothers and sisters trampled into the changing rooms ahead of me. Sleekly-oiled otter fur rubbed against me as they passed, each of their feet slapping against the rubbery pathway with a slightly wet squelching sound. I followed them in, the bag with all of our towels on my back and entry ticket stubs in my mouth.

"Before everyone goes their own way, remember we're at the Canis Hotel. We'll meet up at--" Hugh called out, his voice high and shrill in his attempt to cut through your family's chatter. Chirping grew silent. As patriarch of the family--and my father, it's was his right to be heard.

"They're not kits anymore, dear." Leigh said, walking up behind him. She helped by starting to strip him out of his day-decency clothes. "If they're not there, then they're off having fun with someone else."

"I know." Hugh fumbled. Raising the whole pod of us had been a heroic task. Some habits die hard. "Okay. Don't lose your..."

Dad stumbled into silence when he remembered that our passes were linked to our IDs--implanted and incapable of being lost. Once the lockers closed and we walked out into the park, there was nothing we had to have. Nothing we had to remember. Nowhere we had to be. It was clear confusion that for once there was no fatherly advice he needed to give us.

"Come on, dear. We're here to enjoy ourselves. Stop being patriarch for a few days, and just come be my mate, okay?" Leigh slid my dad's pants down around his squat legs and thick thighs. Hugh shivered.

"Okay. Okay, I give up. All you kids--"

"We're not kids anymore, Dad. I'm older than you were when mom had me." My sister Laiya chirped.

"Fine!" Exasperated, Hugh threw his hands in the air and leaned back against the locker. "All you adults go fuck off! And enjoy yourself, you hear me! You better!"

General cheers filled the air in the cramped locker room at that announcement. Leigh finally managed to maneuver Dad away from his patriarchal position at the head of the family. As I and the rest of my siblings started stuffing our clothes into lockers, I saw Mom stuffing her muzzle down between his thighs.

"Let's do the lazy river first!" Elli, one of my half-sisters by my father, squeaked up. Attention interrupted, I felt her rub against my back as she fought against the too-tight stockings she'd worn. I helped her by lifting her tail as she hopped from one paw to another.

Another squeak echoed from further in. Abbin was stripping his daytime-decency clothes from his hind legs in a hopping motion. Two of the girls assaulted him while his tail was high and he was off balance, sending all three of them into a spin on the rubber-coated floor. "You can, but did you see the zero-gee slides! No way am I waiting!"

The chatter stopped for a moment as a large alien walked in, having to duck through the entryway. Brilliant blue and orange feathers sparkled as their owner found a locker not currently claimed by our rambunctious family. "Don't stop on my account." He whistled as he started to disrobe as well, and within just seconds the otter chirping picked up again.

"I'm hitting the wave pool first." A hand stroked my shoulder, right before grabbing my tail as I dragged your own pants downward. Glancing up, another one of my sisters, Laiya, was standing next to me, entirely naked and ready for a swim. Her whiskery face reached in for a momentary display of affection. I met her halfway in a rub of muzzle against muzzle. "Maybe see you there?"

"Maybe!" I met her muzzle in a whiskery kiss, before she closed her locker. "Got something I want to sort out first."

"Oh? OH! I'd forgotten! Need help?"

"Help? No." I bent and removed my own pants. The warm, humid air felt stifling in the locker room. I was looking forward to finishing up and getting out into the sun. "But I wouldn't turn down company. If, that is, you can steal yourself away from the wave pool."

"Not just company, brother-mine." She mused. Then both of us felt a shove and heard a soft squawk. On the far side of the bank of lockers, it looked like some of my other siblings had already gotten to the bird alien. I couldn't see any details, except for his face above the tall lockers. His beak was open and eyes closed. While we couldn't see anything, the lockers were rocking the the motion of whatever he was doing. "Anyway, we'd better get out of here before they knock everything over."

The two of us scampered out of the lockers. As soon as we exited, sunlight hit my pelt, along with fresh air, smelling faintly of chlorine and ozone cleaners. I stopped for a moment and just let the soft breeze blow between my legs. I was gifted only a few seconds of zen before my sister's snout lifted my tail and nuzzled my nuts.

Before it could turn into anything else, though, we had to scamper off the path to make way for a four-legged tiger stalked past. She winked at the two of us, and I felt a rub of her tail against my flank before she turned the corner towards the wading pools. I felt my ears color.

"Come on! I wanna do this and get to the water!" My sister chirped, and the two of us took the left, where the tiger had turned right.

Ahead of us was a bank of glass-covered displays. Written in garish galactic common, a glowing sign adorned the entry-way. "Gending Machines" it advertised. To our left and right, species-specific body-mods sat waiting to be consumed. Bipedal canids were first on the left, followed by felines and hominids. To the right were reptiles. I quickly scanned along the row, searching for the right one. A moment later, I heard Laiya chirp. In front of her were advertised "Quadrupedal (Mustelidae, Viverid, and Cryptocera)"

My sister had already ordered a slim bottle from the machine. A claw inside grabbed her order and deposited it in a slot. I scanned my wrist where my ID was implanted against the display and chose my own fate. "Cryptocera?" I asked Laiya as the claw delivered my own bottle to me.

"Um. I remember this. Uh. Fossa! That's it. Remember those slinky cat-looking guys with the really big--"

"Nfff" I responded. I remembered, alright. I'd been sore for days, but it'd been worth it. Two knots. What the hell did they need with two knots? And barbs, too? My mouth was starting to water.

"Here, help me with this." My sister gave me her bottle. It was branded as "Strawberry Pop!" On its side was scrawled "Have your fun, your way!" Just beneath that, it had a rather crude illustration of a nude female four-legger with her tail raised. An arrow pointed to the side, and as I twisted the bottle in my paws I could see the picture continue to the same generic weaseloid happily surprised by her new sheath. The bottle top was tight, so I used my teeth to help me turn it.

My sister snatched it back--though I noticed she waited just until the top had begun to twist. "Don't get any of that on you. Not made for you--not sure what'd happen if you did."

I lifted my own bottle. I'd got "Sherbert Shock." It bore the same slogan, though on mine the crude figure was excessively male in the first picture, and in the second he was showing off a cute little slit underneath his lifted tail. That's the ticket. I tore into it with gusto, just as my sister finished extracting the top from hers. She held it upright over her snout and downed the entire drink in one go.

Mine tasted fruity and sugary, without too much specific taste. It was... Fine. I didn't get it for its taste anyway. While I was finishing my drink, my sister was rubbing up against my side. "Nnnnh, I think I feel it."

She wasn't wrong. My lower belly did a little flop. I'd never tried body mods before, though some of my siblings had. Perfectly safe, they'd told me. Little uncomfortable for a few seconds, then lovely. All those new nerve connections make everything feel good for a little while you adjust. I was in "uncomfortable" for the moment, but finished my drink before I could have any second thoughts.

But the second thoughts came quick on its heels. Uncomfortable was an understatement. It was like all of my lower muscles cramping. Laiya held my tail. I felt her claws dig in for a moment--then disappear. Her pained expression cleared, and her eyes shot wide, followed by a wide grin. She was ten seconds ahead of me. I stomped my legs through the discomfort, stretching them to try and alleviate the cramping. But then after half a minute of it, the cramps suddenly faded. I felt good. Great, even. My crotch felt cool, like the first touch of river water beneath the nuts after a day in the sun.

"Here! Here, feel here!" My sister grabbed my hand and jammed it against her crotch. I felt the slim curve of her sex between her hind legs. I was no stranger to it--that's just how our family worked. "No, not there, up further!"

I did, indeed, feel something unfamiliar just a few inches higher. Her fur was starting to fold in on itself, and I felt a wet touch to my fingers where a thin opening was starting to form. I felt her fingers exploring me at the same time. Webbed digits spread over my sheath and pulled my nuts upwards so she could check. There was a shock of warmth as she touched something unexpected. It was like licking a battery. She pulled her fingers back, and between two of her pads was an unexpected film of liquids.

The two of us looked at each other for a long moment. We didn't have to say anything. We were both thinking it. The idea burned bright between us, unavoidable and inevitable. A moment later she was on top of me. I rolled to face her and met her muzzle for a kiss. Then we broke apart. She helped me set my back against one of the Gending Machines so I could see.

Her newly-formed sheath was already looking recognizable and elegant, though it was still slimmer than a male might have. It grew, moment by moment, though, and visible past its brown, fuzzy lips was the beginnings of an intensely pink tip. I reached down to run my fingers over it, and Laiya trilled into my ear. "Oh, do that again!" So I did. Her cock was still growing, so all I could coax from it was a thin spurt of excitement.

That landed across my own crotch. All the uncomfortable rearrangement had made room for the start of my own little slit, which was growing longer with each passing second. My sister used her fingers to spread it, and I saw that the internal anatomy was still very much in progress. Still, it felt fantastic when her pads dragged over my newly-furless skin.

"Okay. This is rather fantastic." I whispered. Laiya seemed to agree. Her whole body gave a squirming quiver. She'd grown to the point where the still remarkably-slim cocktip was just barely starting to point out from her sheath. "Come on. Let's see which of us grows faster!"

The feeling of my sister sliding her brand-new cocktip between the lips of my still-forming slit was bliss. It wasn't really what I'd call penetration yet--I still only had external features forming while she was starting to grow longer. Still, the rubbing against nerves that only recently began reporting to my brain were exotic and delicious. I felt her fingers on my own cock. Given the pleasure, it was no surprise that I was already laying half-out of my sheath across my belly. But nice as it felt, I pushed her hand away. "Nah! I know how that feels. Just show me how the new bits work!"

"How they work?" She pulled her hips back and inexpertly ground her quickly extending shaft against my slit. There was nowhere for her to go, except sliding through my lips and pointing up towards my belly. Hot little gushes of liquid were starting to spurt from her slim cockhead. "The ones you're getting are simple. It's this new thing that requires a user manual!"

She rocked against me uselessly for another half a minute. She was definitely growing faster than I was. After not so long of this delicious torture, though, I felt her tip catch before it bounced up and flopped against my belly. Her fingers spread me again, and this time both of us saw a slim opening forming at the bottom of my new slit. Thick, viscous liquid bubbled up from the new vagina, clear and slick as my sister's cock glid against it.

Her eyes met mine. I licked my lips. She folded her ears back. "Ready?" She breathed at me.

"Please" I begged. Her cocktip had started to grow form and shape, thin and curved, with a noticeable bend and hook at the tip. I teased it with a finger as she aimed herself downwards. She shivered. A gush of her excitement wet my slit before her tip caught in the new opening. This time, there was a plunge. I felt the unfamiliar sensation of being stretched. Of being filled. I leaned my head back against the glass of the Gending machine as Laiya split me open.

My new vagina must have been growing while the external bits were taking form, because there was no barrier and no resistance as my sister thrust. The feeling of skin gliding wetly against skin was both familiar and strange at the same time. I heard a squeak above me. Laiya had closed her eyes. Then I felt her throbbing. Hah! She wasn't used to the way it feels. She'd only been inside me for a few seconds, and already she was gonna blow. I latched my hind legs around her tail as she quivered. I felt a hot rush, and the sensations that had been smooth and slick just moments before turned a sort of silky as her cock pulsed inside me.

I let her enjoy her peak. She was adorable when she squirmed in my arms, and even though she was already at her peak, she was subtly fucking it into me with rolling hips as she throbbed. I felt a wetness against my thigh where her own fem sex was leaking. I wondered momentarily if the two orgasms were linked. Though, if I was going to test that, I was going to need to get my sister to get me off.

Recovery was slow. If it'd been me cumming, I would have been at it for no more than a few seconds, then ready to go again in just a few minutes. Laiya looked like she was still riding a high, as her crotch rode my tail for extra stimulation. Well, she was new to having a cock. Maybe her body was still working on familiar sensations channeled through a new set of nerve endings. But that was a query for future-Laiya, because present-Laiya had a job to do. She sat up and gave me a rather guilty smile. Mom and dad had taught us well. This wasn't over until I was sated too--even if it was with entirely new body mods. Laiya sat back, and her new cock slurped out of me with a rush of her cum following it. Oh, that felt strange as it was dripping out. She was fully grown at this point--at a length not far different than mine and a girth that I think was slightly wider. Her fingers spread my lips, and a thumb slid upwards towards their peak.

It was as if someone had just found the "orgasm" button and jammed it. Maybe it was because everything was still so sensitive, but it was both shockingly immediate and intensely pleasurable. My sister let out a pleased chirp as I peaked. Her leathery finger pad slid over my brand new clit as my knees shivered. I felt my cock flop against my belly, and a moment later it was throbbing up into the air and making a mess of the glass near my head. Well, that answered that question. Laiya lapped at my twitching tip as she ground her thumb against my button.

For all that I'd heard the girls in my family could cum for minutes on end, mine faded quickly--not so unlike the male orgasms I was used to. I wondered if perhaps I was still wired that way--male with just some extra bits to enjoy. I decided that was fine. Fantastic, in fact. I was still "me." And that was exactly the way I wanted to have fun. I saw the same satisfaction in my sister's eyes. She stood up on wobbly legs. I followed her back down towards the trail, both of us leaking a thin trail behind us. As we descended, an automated drone slid through the bushes up towards where we'd been. This resort knew what its guests were here to do, and their housekeeping was well prepared.

At the intersection of paths was a small hand-pulled shower. We waited while another couple rinsed off. A suave feline stood beneath the spray, rubbing her fur down towards her crotch, which was matted and wet. On a leash she held, a diminutive mouse stood meekly at her knee. The little guy was so short that his ears only barely reached the cat's thighs. It looked like she'd taken advantage of his diminutive stature, because his whole body was matted with his juices. His tiny cock hung limp and dripping from his sheath, though, so it appeared that he'd gotten his, too. When the big cat was done, she moved aside so the messy mouse could rinse off.

A minute later, Laiya and I had our turn. We snuggled together beneath the cool shower. She was fingering my now fully-formed slit, while I was rubbing fingers over her sheath and the tip that was sticking out in anticipation. The day had only just begun, and there was a whole park to explore--not to mention its many inhabitants. And we had all week. She met me in a loving kiss in the shower before she flounced off towards the wave pool. Feeling frisky and with a whole new realm of possible fun ahead of me, I took a different path, off into the vastness of the Wild River.
