Tentacle Monster Problems by Zmeydros

The college track team I was part of had just finished its first training session of the season. I'd nearly forgotten how to fake fatigue and had to take some cues from my teammates. I followed close behind them on our way to the locker room huffing and puffing and sweating. Sweating was such an annoying thing to emulate. It was gross and I had to drink and eat the right stuff to get my electrolytes back. Brine belonged in the ocean, not on my skin.

The scent of damp things long forgotten hung in the locker room air as I walked up to my ancient crooked-hinged locker. If the showers weren't rigorously cleaned, I probably would have left the team ages ago.

Showering with the other girls was my favorite part of being on the team. Intimacy with humans was out of the question, but at least I could watch their naked bodies bend and flex as they cleaned themselves.

But that fun would come later, after my team and I shed the clothes that were forced upon us by the strange human quest for decency. I ran my hand over my sea green locker door. The texture of the cracked enamel reminded me of a crab's shell. I opened the door just as Heather started taking off her bra.

Staring from the corner of my eye, I feasted on her form. Her sports bra had to be industrial strength to contain her wonderful full chest. No matter how much she ran, her body remained supple, something I'd want to wrap myself around and feel her buck against me until she came.

As I watched her bend down to pull her pants and panties off, I pulled off my top and bra. Then my pants and panties. The yellow and black of my track uniform looked much less proud in the dim light of my locker.

Heather turned to me and said, "Oh, Amy, do I have some amazing news for you!"

Her habit of chatting with me when we were both nude made me want to entangle her in my limbs all the more. Casual nudity was the best kind of nudity. It felt quaint, sensual.

"Oh?" I raised an eyebrow.

"Natalie and I broke up over summer break."

"Wouldn't that be bad news?" I asked trying to feel sympathetic. I'd never met this Natalie and, from all Heather's complaining, she sounded like a difficult partner.

Walking up to the locker next to mine and leaning on it, she said, "Nope, she outed me by telling everyone at my dad's family reunion we were a couple. She said she was doing me a favor. Good riddance!"

"That's awful!"

"Nah, it's fine for several of your cousins, aunts, and uncles to go out of their way to tell you how concerned they are for your soul. That's the best way to spend a family reunion, yep." Her beautiful thin expressive lips were turned down as she shook her head.

My arms were around her before I realized what I was doing. We'd hugged before, but never when we were both naked. At first, she froze in my embrace, but then she sighed and hugged me back pressing her wonderful round breasts against my petite ones. I'd made a mistake. My pulse became so fast that my entire form twitched. I had to focus to keep my body from going on autopilot.

When I tried to let her go, she squeezed me tighter. "You've always been such a good friend, so kind and such a good listener. And I love how I have to stand on my tiptoes to whisper in your ear."

Firmly taking her into my arms again, I said, "Right back at you."

She reached down and cupped my bare ass with her hands. "I've seen the way you look at me."

I couldn't contain my blush, it started in my cheeks, but quickly spread down my neck and across my breasts, reaching around to my back and buttocks. If she'd been standing back and observing me in that moment, she would have thought I had a full-body sunburn.

"The way I look at you?" I was both elated and terrified.

"Don't get all shy on me, I was hoping to ask you out."

My explanation of why that was a bad idea came out as, "Uhh, we can't."

"What? If it's another girl, she's going to be jealous that you're groping my ass."

That's when I realized I was digging my fingers into her buttocks, feeling her toned muscles, holding her hips against mine. "No, if we, you know, you'll change in ways you might not like."

"I bet sex would help us be way less awkward around each other. I'd like that change."

"That's not what I meant."

She let me go and stepped back with a pout on her lips. "If you don't want me, just say so."

"No, I do want you, it's just..." I sighed in frustration not wanting to formulate a lie she'd believe more than the truth.

Layla called out from the entrance to the shower room, "Just fuck already!"

Heather blushed and called back, "Maybe we will!"

"It's about goddamn time." She huffed.

I watched her pull her red hair out of her ponytail before stepping into the shower room. Her long legs and slender form went well with her graceful gait.

My eyes found the blush on Heather's face and then darted between her legs as I caught the scent of her arousal. This set my body to throb and fight my control. Both of my hands reached for her breasts.

When I tried to pull my hands back, she grabbed them and put them on their target smiling wide. "Grope all you want, hon."

Feeling her warm supple cleavage under my hands, I lost my internal battle and my skin started to release powerful pheromones. I took my hands off of her and spun around taking deep breaths. I had to calm down.

She moaned and stepped forward pressing herself against my back. One of her hands dove for the smooth mound between my legs as her other hand grabbed my right breast. "You're so fucking hot!" she said a bit too loud.

Pheromones poured out of me as I became impossibly wet. Every inch of skin that was touching her sent constant pleasure through me. This was what my body was built for, what it lived for.

The two girls already in the shower, Layla and Gabby, stared at me with slackened jaws as Heather slid her middle finger into me. She swirled her digit inside me, teasing my flesh to see how much I could stretch. I arched my back and cried out drawing the attention of the two other girls still in the room with us. They ran around the lockers to find me getting finger-fucked by Heather.

Sadie's brown eyes went wide and she darted back behind the lockers. Brenna grinned like an otaku at an anime convention. She was the other bi woman on the team, the girl I almost fell for. Her strong legs and toned belly spoke to her intensive physical training. She'd been on a women's basketball team in high school, but switched to track in college because she was tired of getting injured on the court.

All the attention only made me moan more. At this rate, I was gonna orgasm and completely lose my grip on myself. Sadie peaked from around the lockers blushing furiously. My pheromones had gotten her too.

This was bad, so very bad! Using the last bit of self control I had left, I pulled Heather's hands off of me and said, "Let's not have our first time in public." I turned around. "How about we take a shower and then get our first date scheduled?"

If I could wash and calm down, there was still hope for these girls walking out of here unaltered.

Heather bit her lip and puffed air out through her nose. "Fine, you have a good point."

"Aww, but I was enjoying the free porn," Brenna whined.

As Heather walked past Brenna, she felt along Brenna's flank saying, "Next time, you should just join in."

"You serious?" Brenna asked.

Heather leaned in and kissed Breanna full on the lips before saying, "Sure thing, hot stuff." She turned toward me while feeling up Brenna's backside. "You wouldn't mind one bit, would you, Amy?"

Heather and Brenna had always been rather free-spirited. That's why I thought they were worthwhile humans. Subduing my full-body blush was near-impossible and the chemicals I'd put into the air were stoking their lust encouraging their rebellious natures, giving them that little bit of courage they needed to suggest a threesome. Maybe this wasn't so bad after all. If all of us were dating, I could set them up doing sexual things together and not get as closely involved in the actual sex. I'd have time to plan, to make sure my libido was well under control before the date so I wasn't blindsided like I'd been today.

"After we're all cleaned up, how about we plan a date for all three of us?" I suggested.

Heather bounced excitedly. "Oh my God! I would love that!"

"As long as that date ends with you straddling my face and Heather between my legs, I'm in," Brenna said.

I grabbed my shower basket and then closed my locker door. As I passed them, I said, "Thanks, Brenna, now I'm gonna need an ice cold shower."

Brenna called after me, "Ice cold shower? Sounds like you're going to need us to help keep you from getting hypothermia."

Heather said, "Yeah! We're gonna make sure you stay nice and warm."

"Sex in the locker room shower isn't what I'd call a good first date," I reminded them hoping that would be the end of it.

Now that I was walking into the shower, I noticed that my pheromones were being nicely diluted by the size of the room. Gabby was rubbing her hands sensuously over her powerful but compact body and Layla seemed a bit too interested in her own breasts, but that was it. Things would be fine. I cycled through a deep breath letting go of my worry.

Brenna and Heather walked into the shower taking up spots on the wall opposite mine. I'd purposefully taken up the spot between Layla and Gabby to deter my prospective girlfriends from further lewd behavior.

Sadie took up the last shower head on my wall, her eyes drifting to look at me every so often. She was lightly toying with her clit as she washed her sex. That didn't worry me, she'd gotten a more solid dose of my pheromones, after all. What worried me was Brenna and Heather's giggling. I didn't dare look behind me for fear of encouraging them.

They chattered quietly as I lathered myself with body wash and then rinsed it off. As I reached down to grab my shampoo, someone's hands spread my butt cheeks and something hot and slick ran over my labia.

My sharp moan as the offending tongue entered me drew the eyes of everyone in the room. With my mind being completely unprepared, my body released a plume of my lust-inducing compounds.

Brenna dashed in front of me and put my gasping mouth on her pussy as she tilted her hips forward and leaned on the wall to give me better access. The taste of her was exquisite, like iced tea mixed with lemonade. My tongue couldn't help but delve into her as Heather dipped into me with reckless abandon.

Layla, Gabby, and Sadie were openly masturbating as they watched the lesbian sandwich that had been assembled around me. A low groan vibrated through my whole body as my skin turned hot pink and became more rubbery to the touch. This was bad, I'd toppled over the edge and was careening toward my true nature. My last ditch attempt at remaining in human form was to focus as much as I could on getting Brenna off. If she came, there was a chance she'd be sated and there'd be one less partner to worry about.

My pheromones were thick in the air. Sadie was now between Gabby's legs eating her out while Layla was sucking and licking at Brenna's nipples. I rubbed my lips on Brenna's snatch humming and moaning into it while licking as deep as I could. The little ridges inside her, everything about her texture, made me never want to stop. She shoved two fingers inside Gabby as she rocked her hips and watched me with adoring eyes. Her breathy calls of pleasure signaled she was close.

I sped up my motions and ground my face against her. She rewarded me with an avalanche of her nectar which I lapped up like a cat with a bowl of milk. As she screeched and hollered, she bucked against me squeezing my tongue inside her. I savored her ecstatic gyrations.

Heather grabbed my attention by twisting her tongue to stir my intimate flesh showing off her Olympic-level cunnilingus skills. The pleasure made every ounce of me ache. That ache became a throb which became a wave of ecstasy. This was the worst, best, thing that could happen to me. As my snatch grabbed at Heather's tongue, the four tentacles that made up each of my legs started to separate, breaking the seals that they'd made with each other to appear whole. I sputtered feeling my slick rubbery skin slide over itself for the first time in ages. Eight more tentacles pushed out of slits that ran up my back.

My teammates smelled so good, so ready for me. All of them were rubbing against me, kissing me, licking my sweet, undeniable, flesh.

Heather guided two of the tentacles from my back to her breasts. I clung to them with my suckers and she groaned happily. Brenna was still idly rubbing herself against my face seemingly unaware of my changes. Sadie was straddling one of the thick tendrils that had been my legs slicking it up with her pussy. Gabby was doing the same. Layla was pressing one of my tentacles into herself.

I wanted to embrace these wonderful women, my friends, I wanted them to feel as good as they made me feel, to play with their bodies, and give them new forms. It was instinct, it was desire, and it was my purpose.

They were too aroused to fear the the drastic change I was about to afflict upon their lives. A part of me held hope that they would fall in love with themselves all over again. That they'd see their new forms as beautiful.

The rest of me was a twitching pre-dripping mass of lust. My teeth sharpened as my nose pressed forward and flattened leaving two nostrils at the end of my pointy shark-like snout. My ears grew out becoming more fin-like. My breasts gained a bit of mass under the power of my own will. I wanted them to be squeezed and toyed with.

Brenna shivered as I wrapped two of my flexible limbs around her legs and pushed her back against the stark white wall tiles. I shoved inside her shivering as I felt her hot passage spread for me. Grabbing Gabby around the chest and waist, I held her above me. Her breasts felt magnificent wrapped in my tendrils. Twisting two tentacles around each other, I entered her and she cried out in delight. Layla already had me inside her, so I simply pressed in further, making her gasp happily. I grappled her arms to help her stay upright.

Hugging Sadie against my side, I stuffed her. She tightened wonderfully as she toyed with the tapered length I'd put in her. Wrapping Heather in multiple tentacles, I pulled her to my front and held her breasts and hips against mine as a slit opened in my crotch and my cock spilled out. Though the head and shaft were thicker than my tentacles, she took it easily and I found myself rutting her hard enough that her breasts bounced deliciously against mine. I used my long tongue to toy with her mouth as I gave the other girls something to suck on.

Their cries of passion became interspersed with sucks and swallows as they found themselves in deep need of my pre. I wiggled, twisted, and undulated inside them giving them pleasure they'd never imagined.

The waves that crashed through their flesh due to my thorough fucking were testament to my enjoyment of their bodies. Heather came first, then Gabby, then Brenna as I stretched her by adding a second length to her snatch. Sadie rubbed herself lewdly against me as she came and Layla let loose a triumphant yell as her passage spasmed around me. I reveled in their orgasmic motions as I continued to ravish them.

Only a few minutes later, another release spread through them like an electric shock. The jubilant tingles traveling down my tentacles were now making it to my core. Something beautiful was blooming inside of me. My imagination swelled as I contemplated what traits would suit each woman the best.

This time I carefully drove them to climax at the same time, so we all came as a team. My trilled screeching joined their euphoric cacophony as my body contracted from center to perimeter. There was no part of me that wasn't electric with bliss. It felt as though the entirety of my being was being fucked at the same time.

My life-changing essence spilled into them making them tremble and fidget as their muffs milked my tentacles. I couldn't help but squirm as I was held in the embrace of overwhelming joy. Knots swelled on every one of my tentacles sharing a tight hug with their inner walls while holding my bounty inside them. This sensation had me feeling wonderfully close to all of them.

Out of all of them, I'd stuffed Heather the most. She'd been riding my cock, after all.

It seemed to take hours for us to come to rest. I'd been so pent up that excess seed had spilled out of them before I could knot them properly. Removing my tentacles from their mouths, I said, "Now comes the fun part."

"That wasn't the fun part?" Heather asked looking more relaxed than I'd ever seen her.

"You'll see," I said too full of bliss to bother myself with a proper explanation.

Layla said, "So, you're like an anime tentacle monster?"

Sadie spoke up before I could reply. "Like an alien?"

I nodded. "Yeah, actually."

Sadie grinned and hugged my side. "You're a fucking awesome alien!"

"Yeah, babe, that was the hardest I've ever cum in my life." Heather touched her nose to mine.

I nuzzled her saying, "I should have asked before sticking a dick in you."

"Women use strap-on's all the time." She shrugged.

Brenna laughed. "You've got like seventeen dicks, Amy. I have no idea what box to put you in."

"Neither do I," I admitted.

Gabby said, "Hey, umm, I'm still horny..." She blushed.

Heather bounced on my shaft, "Me too!"

"Me three!" Layla said squeezing me inside her.

Brenna moaned. "This is so crazy!"

Sadie rubbed herself against me. "Move that tentacle-dick-thing inside me some more."

Layla's eyes went wide as she said, "Wait! A-are we gonna have alien babies?"

Every girl stopped and stared at me. "No, no, no. Nothing like that... but--"

They all went back to humping trying to coax me to start moving again before I could try to explain further. My pheromones had such a strange effect. I marveled at the situation in awe of my power to entice them.

Heather was the first to notice something was off. The skin on her front was losing its color as it became bright white. The skin elsewhere was swiftly darkening She said, "Uhh, something feels strange," when a slit formed above her pussy.

"Just you wait, it will start to feel amazingly good." I rubbed at her slit with my fingers as the pink tip of her new orca cock poked out.

She grunted and thrusted into my hand as inch after inch of her new length formed. She twisted and coiled her new appendage, captivated by this new, powerful, source of pleasure. I entangled a tentacle with it as her nose closed off and a blowhole formed at the top of her head.

Gabby, Brenna, and Sadie grew fur while Layla's skin was covered by patches of scales. The changes caused pleasure so acute that they could hardly catch their breaths. Sadie started thrusting herself against me lewdly as her light brown bunny fur made its way down her legs. The head of her brand new horsecock was leaving a trail of pre on my side as she humped me. Her balls filled in to accompany her length. I reached in with a tentacle and teased her sheath which drove her wild.

Brenna was also growing a handsome set of balls. They were covered in her grey wolf fur and just starting to dangle below her sheath. I coaxed her canine prick out as she clenched her jaw. Suddenly, she said, "Let me go! I wanna touch it!"

I did so, but kept tentacles lodged in her pussy. She started stroking herself madly as her prick extended further and further into her grip.

Layla hissed in pleasure as I started stroking her emerging ridged dragon shaft with a coiled tentacle. Her draconic muzzle was swiftly filling in with pointy teeth as scales redder than her hair covered her body. I became fascinated by the texture of her scaly package as it reached full size.

In fact, I loved the texture of her scales no matter where they were. I found myself stroking across her whole body feeling different intricate patterns of rough and slick depending on which direction I crossed the little diamonds that had replaced her skin.

Gabby's fur was thick and ideal for aquatic life. She was going to make a terrific otter hybrid. Her swelling sheath drew her attention as I teased it. She kept staring at it, and me, in awe while letting loose a litany of pleasure-laced exclamations.

Out of all of them, Sadie was impressing me the most. As her nose became petite and pink, she rubbed her whiskers on my shoulder petting herself. Her ears became more and more massive and started to flop as they didn't have the structure to stay standing yet. Her equine poll felt exquisite against my side. It was so massive, so meaty, so sexy!

I groped her balls finding them to be as large as plums and said, "You're gonna be the best hung out of all of us."

"Yes! Please keep changing me! It feels so good!" She spurted pre as her pussy came around me yet again.

I was glad all the pleasure had cut through her shyness. She often seemed too nervous to allow herself to have fun. Her ears began to perk up. Soon she was able to twitch them along with her cute little bunny nose.

My body pulsed over and over, delivering the materials they needed to keep changing. I was being inundated in bliss as it came time for tails. Sadie's was underwhelming, but cute. Brenna came all over me as hers pressed out growing bushy wolf fur. It looked like someone slowly revealing a pipe-cleaner. Heather's took longer and was a sight to behold. First it was a somewhat stubby growth with a thick base, but it extended farther and farther as the end flattened like dough under a rolling pin and split to form an orca fluke.

As she got her tail, her cock contended with two of my tentacles trying to find the most pleasurable entanglement possible. Our moans got higher and higher as we both reached a thundering climax. It felt so good to have something with the dexterity and flexibility of my tentacles writing within my prehensile grasp. It was like having pleasure sensors on one's tongue while french kissing. Friction from a myriad of unexpected and fascinating angles, the sensation of tender slick muscular organs sliding across each other in infinite arrangements of front, back, and side.

As she splattered cum on my breasts and neck, I came making an even bigger mess. My pleasure was further heightened by my unique skin absorbing our mess along with Brenna's.

Gabby's thick cream rained down from above as her massive otter tail erupted from her buttocks. As she writhed, her body lengthened giving her greater flexibility. I grinned at her hybridized form as I finally set her down on the floor. She just lay there with the water soaking into her fur, eyes closed and at peace.

Layla had already been slender, but her neck gained a couple inches magnifying that effect. The tail that slowly took shape, pressing out from her like a python trying to sneak up on its prey, was magnificent. It glistened with reflected light as it twisted and flexed and explored its surroundings.

Soon, it became entwined with my tentacles and started showing off its strength. I was so enthralled by its scales that I was surprised by Layla's jets of passion. Once I had absorbed her bounty, I'd sampled everyone. Every woman's genetic makeup was now a work of art.

I watched in wonder as Heather's orca snout finished coming in and Brenna's nose became cold and wet. I stroked along their faces loving the sensation of finishing their changes. Layla's ears gained in length and pointyness as she got ivory horns that swooped back elegantly from her head.

Once Brenna's muzzle was complete, she started stroking herself and growled, "I need to fuck something."

"Yeah! I wanna use this thing!" Sadie's erection stirred against my side.

I teared up. They were complete, they were perfect, they were gonna fuck me till I was sated. Sated for the first time in my life. I freed them from my embrace.

Brenna grabbed two of my leg tentacles and worked to clear a path to my pussy. As I moaned and gasped, she positioned me just so and shoved in. Layla grabbed my head and forced me to bend down. She shoved that ridged dragon member into my mouth.

Heather bent over and spread herself saying, "Sadie, get in here!"

As Sadie's gigantic erection disappeared into heather, Gabby grabbed onto Layla and shoved herself in. Layla spewed pre in my mouth losing control of her hips. She pushed the end of her draconic tail into Brenna as Brenna started pounding me. Benna was so hard, so strong, and so thick at the base!

I trilled as my pussy was stretched wider and wider. Brenna's knot was inflating gradually as she stuffed me over and over. My tongue wrapped itself around Layla's textured length so I could relish in every ridge. There was a knot at her base as well. I teased at it and it got bigger and she got closer to going over the edge. As Brenna got big enough that there was a definite popping as she went out and in, I couldn't help but get excited.

Her strong paw-padded hands each gripped the base of a tentacle as she thrust so hard my breasts bounced.

Layla grabbed my head and said, "Oh Amy!" as she came in my mouth. She tasted like hot chocolate. So creamy, so sweet, with a bit of tantalizing bitterness. I came from the taste alone. She was a masterpiece, all of them were.

The orgasm was like a strobed flash that bounced off every surface inside of me. It seemed to grow in heat and intensity and just when I thought it couldn't get any better, Brenna made one last thrust locking me to her with a knot so big that it fit the rest of her perfectly. Pressing her thumb against my clit, she came inside me filling me with something so thick and rich that my orgasm gained another layer of ecstasy.

As I was in the throes of my orgasm, Sadie rammed home inside Heather and came so much that she'd make a stallion proud. Heather squealed as her prehensile length twisted and flailed. Gabby's passionate chitters let everyone know she was losing her virginity to Layla's pussy.

I had no idea what the future would bring now that I'd turned my teammates into freaks. But all of us were too busy feeling amazing to care.
