Jane and the Mimic

The following story was inspired by a "Choose Your Own Adventure" post on reddit.com/r/tentai. (https://www.reddit.com/r/Tentai/comments/7g9f1s/tentacle_pet_choose_your_own_adventure/)

CHAPTER 1

    I'm starving. That was all I could think as my mind slid back into place. I blinked at the uncomfortably bright overhead bulbs on my ceiling fan, then closed my eyes again. The room was cold against my skin.

    I had never been a large person. Before the Offer—what I was calling my interdimensional encounter now—I had barely been four feet tall. I'd always been the dwarf; I was way too short, and so I was way too thick. I had learned the word "spinner" in my freshman year of college. For a few months, I had thought I fit in. How wrong had I been? After I realized the frats and sororities were using me like an attraction for their parties, I had dropped out and run, too ashamed to look at anyone I had ever known again. Two years of retail in a small city, the tiny ginger girl. The fucking leprechaun.

    It was a dead-end. I knew that. I had known that for two years. But that was the point, wasn't it? I wasn't a good fit. I would just follow my dead end road until it hit the cliff. Drugs, probably. Shit, I'd die happy, at least.

    Then, Ra'ito found me. Not a person. A company. Ra'ito was an interdimensional medical and genetics corporation. They dealt in everything from health products to livestock strains. They had offered to reshape me if I would help bring their brand into E-302—their name for my dimension. I took them up on the offer in a hearbeat. I was going to be six-foot-two now, and I would date a fucking basketball player or something. I thought about sitting up, but my head was still spinning.

    As a side effect, I would be forever young and fit, with a runner's body for life. They were even going to sculpt me while they stretched me! I could be a fucking supermodel. But I really wanted to run. They said they could make me an athlete, and that's what I'd asked for; lithe muscle and killer endurance. I rubbed my head, blinking slowly once more and finally opening my eyes. Fuck, was I hungry! I rolled off of the couch, reaching my leg down to stand. I missed the ground and fell clumsily into the carpet. I chuckled at myself; some things couldn't be fixed by height and strength.

    As I finally stood up, though, I realized that something was horribly wrong. My eyes were barely level with the back of the couch. Even I wasn't that fucking short.

    "Son of a bitch!" I swore as I looked down. My legs weren't toned. I mean, they weren't stubby like they had been, either. But they were short and slim. My feet—although down a few sizes—had never been closer. I began feeling my body, then ran to the floor-length mirror in the bathroom.

    My vivid green eyes glared angrily at me from the looking glass. My red pixie-cut tickled the tops of my ears. I hunched more than usual, supporting two breasts unchanged in size, if perkier. I had been shrunk another foot! I wasn't a leprechaun, I was a fucking pixie. I mean, I looked cute as hell, which was better than a stocky little soul-eater, but I wasn't even big enough to be a nymph; I was a damn flower-fairy. I swore at the mirror-me, who kept in vulgar lockstep until I gave up and returned to my small living room.

    There it was. The little phone that Ra'ito had left with me. I flipped the comm open, ready to tear a new asshole in whatever poor service rep answered the call. Thing was, I couldn't turn the stupid thing on. It was locked, refusing my DNA. I swore louder than ever, chucking the thing at the sofa. Fuckers ran a genetic engineering corporation and couldn't even remember to update the phone after they fucking updated me. Cunts. I stumbled towards the kitchen, desperate for a sandwich or something. I wasn't used to the shorter legs. Probably would have had the same problem with the longer ones I had fucking asked for.

    The ever-looming cabinets now towered over me. I had to climb onto the counter to get to my breadbox; the stepstool had only barely been enough to begin with. I found my bread green with horrendous mold. I wasn't that hungry. I tossed the loaf at the trash can, letting it know how ugly its mother thought it was. The bread, not the trash can. I kept rooting through the cabinet, eventually settling on a lone pack of Nabs. Thank god for fucking snack-packs. I inhaled the crackers—only choking twice—and made my way to the bedroom, killing the lights along the way.

    I jumped onto the bed and cut the last light, laying back and thinking about how the hell I was going to get in touch with Ra'ito again if my phone was locked. The only light in the room was the faint glow of the street-light outside of my apartment, barely sneaking in around the curtains. I was torn between sleep and anger; now that I had eaten, I realized how tired I still was. For a few minutes, my thoughts wandered as I pinched various bits of myself, tugging at my waist, thighs, arms; I was like forty pounds now, and that looked right for my height. Those dicks. I muttered at no one in particular, "Fucking bitches. Fuck you. Is this some sick fucking joke? You know there's like eight billion people you could fuck with, right? This, right here? Yeah, fuck you."

    No one answered. Duh, dumbass. That's why you have a phone. Determined, I rolled to the edge of the bed. I was about to carefully step down when I saw a flicker of motion. My heart instantly raced, pounding in the silent darkness. I stared over the edge of the bed, then rolled back. It took a minute, but I eventually convinced myself that there was nothing there. I took a deep breath, then swung my legs over the edge.

    The room filled with a faint blue light, pouring from under the bed. My eyes went wide as something misty shot from under the bed. It was the source of the light, some sort of roiling tubing, but there was a veil of darkness around it. It was some sort of fog, the mist of hot, damp breath on a cold day clinging to... whatever it was. I snatched my legs back up over the bed, but too late. One of the tube threw itself onto the bed, bathing the sheets and my own flesh with the pale blue light and a sheen of some slick fluid.

    I rolled across the bed, throwing my legs towards the wall. Three more tubes landed on the bed, and then began snaking towards me. Only now did I finally scream. "What the fucking fuck fuck fuck—" I was cut off as the tube wrapped itself around my stomach, squeezing the air out of me. My mouth opened with a grunt. A second tube wrapped itself around my ribcage, just below my tits. I reached for both of them, writhing as they slithered around my torso once, twice, then stopped and just squeezed. The tubes were slippery but covered in nubs that latched onto my flesh, locking them in place. Suckers. These were octopus tentacles?

    My squirming died down quickly as my shallow breaths failed to net me the oxygen I needed to continue. I stopped kicking my legs and beating my arms against the slimy, glowing tentacles, instead squeezing my knees together tightly. Fearfully. A third tentacle grabbed my waist, pinning my forearms to my side. The fourth and final appendage wrapped around my calves, leaving me practically cocooned in what felt like warm jelly. The tentacles were as big around as my arm and—given my breathing difficulty—were significantly stronger. I panted shallowly as the thing dragged me towards the edge of the bed. I fell the couple feet, my head hitting a soft mat that felt like another mattress. The mat slowly slid across the floor, dragging me under the bed and into the heart of the glow.

    When my vision had nearly gone black from hypoxia, the tentacles loosened and withdrew, leaving me on a slimy, glowing mat with tiny wriggling bumps. I gasped for air, trying to remember which way was out or how to make the weak flailing of my limbs drag me back into the room. By the time my senses returned, hundreds of two-foot long filaments had pinned me spread-eagle on the mat, which writhed enticingly below me. I didn't bother straining against the tendrils; I had seen exactly how athletic the fuckers hadn't left me. The tendrils and mat slid across almost every inch of my body, each individually demanding more attention than my brain had to give. I swore. "Hey, dickf... Hey dickface," I managed around deep breaths. "I command you to stop."

    The tendrils briefly halted. The bed above me lit up—the entire thing, frame and all—and shook. The motion was accompanied by a low, rhythmic sound. Laughter. A new tendril burst through the glowing bottom of the mattress. This one was bigger. The size of a few fingers held parallel. It began prodding at my body. I grunted as it circled my breast.

    "You have to stop. The pamphlet said so. Ra'ito's tentacle pets have to obey their master. Stop this immediately." The tentacle gently squeezed at the base of my breast. My eyes fluttered. "I fucking told you to stop, you cock. I'll have you put down for this bullshit." I tugged hopelessly at the tendrils around my arms and legs; I couldn't even get my knees off of the mat.

    Another laugh shook my bed, the amusement of the creature within. The fabric covering the bottom of the boxspring cracked into a smiling mouth full of rotting yellow teeth. Its voice blasted from the enormous opening. It was overwhelming and grating, the cracking of rock in an earthquake. "I must obey my master," it explained. "But you are not my master."

    My eyes went wide. The phone didn't respond to my DNA. The monster didn't respond to my voice. They hadn't just fucked up my order. "Fucking FUCK. They swapped me with another customer?"

    As I watched, the bed slowly morphed. The beast wasn't inside the bed, it was the bed. I swore again as it slowly became a towering blob of what looked like rotting flesh with a huge mouth and three mismatched eyes scattered across its main body. I cringed at the sight of the huge, yellowed teeth as it spoke again, but the tendrils prevented me from turning my head aside. "Not you. Just your order. And, it seems, your Ra'iPhone." It grinned wide, the tendrils squirming between my toes and fingers. It felt delightful, and I hated it.

    Now my heart was racing with fear and arousal. I knew what Ra'ito's tentacle beasts were for, and part of me had considered renting one for a night. But I would have gone with a tiny one, like a little octopus. This looked... evil. Its monstrous grin grew wider, tombstone teeth looming over me. "Don't eat me!" I screamed. "You have to let me go I command you to let me go fuck you fuck off fucking LET. ME. GO!"

    I kept screaming, calling it progressively more creative and absurd names as the tendrils tickled between my digits and a second tentacle began encircling my other tit. "I'm not going to eat you, Jane. I'm going to give you that which you have always desired. That which no one has since your mother's passing. I'm going to give you love. Unconditional love."

    The tentacles on my breasts flattened out and ruptured at the tips, becoming wide, sticky stand-ins for human hands. As they dug roughly into my new tits, I swore more loudly, condemning the beast and nearly convincing myself that I wasn't aroused. "You dick-brained zombie, this isn't love. Fucking let me go, rapist bitch! I swear to god, I'll have Ra'ito pull those disgusting teeth out of your head one-by-one!" The blob rapidly shifted back into a bed, the blue glow intensifying across the surface of the cloth and the tentacles alike. The closeness of the bedframe combined with the tendrils pinning me in such a vulnerable position left me in a claustrophobic panic. A new tentacle caught my attention. A brightly-lit spider-shaped appendage. I screamed, flashing back to watching Alien in a dark room. The tendrils around my neck abruptly tightened, denying the cry. When they loosened, the threat remained. I whimpered softly as the slimy blue spider launched itself at my pussy.

    Its legs wrapped powerfully around my legs, biting into my waist and ass. Simultaneously, the tendrils and breast-grippers released me, leaving me on a mat of slime. I snapped my legs together; even when my knees touched, the grabber remained latched onto my waist. I swore again, then squirmed out from under the bed. I was now coated with slime, which stuck to the floor—now that I had escaped the mat of cilia—even as it was slick against my flesh. It was selectively either a lubricant or a glue. I stood shakily and stumbled across the dark room. My only sense of direction was "don't go towards the light." The mat beneath the bed still glowed blue, as did the tentacle latched onto my cunt with its stupid, rock-solid fingers. Beneath, the flesh and slime formed a perfect seal as the tentacle sucked on my whole mound.

    I stumbled against a wall, where the slime glued my back to the plaster. I reached down for the latch tentacle as its fingers flattened further, forming a tightly-locked pair of underwear. I couldn't even slide my finger under the edge; I was sealed airtight. My hands grabbed frantically at the tentacle itself, but it was too slick with the self-repelling slime, and—thin as it was—it was as strong as steel chain.

    The tentacle jerked, pulling me off of the wall and to my knees. I had to use my hands to stop my fall. "Please, you're supposed to listen to me." It jerked again, spinning me around such that I fell face-and-tits-first into the puddle of slime, adhering to the floor. I received no mercy as I tugged at whatever my fingers could grab. The latch tentacle went taught, dragging me by the hips towards the nightmare beneath the bed. I screamed aloud once more.

    "Fuck you, you sick... fuck. Get the fuck OFF of me!" I brought my heel down on the tentacle, scrambled to my feet as it went limp, and ran towards the door.

    I threw the door open and ran into the living room, stumbling when the tentacle went taught once more. "She wanted you," I said. "Go back to the bitch who wanted you." Slime formed a growing puddle on the floor beneath me. "Fuck you," I shouted as I was pulled to the ground once more. "You're ruining my apartment, asshole."

    I propped myself up on my elbows, but the slime was too sticky—and my starved body too weak—for me to stand. The glow beneath the bed intensified and the latch tentacle began to grow at its base. The growth moved like a wave towards me, thickening the tentacle as it went. I screamed now, unable to think of insults or curses to throw the monster's way. When the thickness reached the latch, I felt a flat-headed tentacle press itself against my pussy. I let myself fall to the floor again, grabbing, pushing, and kicking at the tentacle. It went taught once more, pulling me across the floor.

    There was a rumble like laughter again. This one reverberated down the latch tentacle until it reached my pussy. The flat-ended inner tentacle began to vibrate violently, grinding against my clit like a Hitachi. "Fuuuck!" I screamed, reaching for the doorframe. The latch pulled harder, sliding me along the floor and closer to the bed, the only source of light in the apartment. "You piece of... shiiit..." My cries dragged into a whimpering moan as the vibrating tentacle brought me to the edge.

    "See, Jane? I'm not trying to hurt you. I would never hurt my mate." As he said the word mate, the inner tentacle surged forward, pressing into my cunt greedily. I fell off the edge as the vibrating tentacle the size of a magic-wand slipped into my pussy, my limbs going rigid as I came as hard as I ever had in my life. For the better part of a minute I forgot where I was, wrapped up in a powerful orgasm. When I looked around myself again, I was back beneath the bed, surrounded by blue light and tendrils again.

    The huge tentacle was sliding in and out of me. No, it was a cock. It was fucking me. Mate. I opened my mouth to scream again, only to have another spider-like latch tentacle drop onto my face. It wasted no time in gagging me, a smaller tentacle pushing past my lips and forcing my jaw wide. Tendrils gripped and caressed my limbs while the tentacle below began pistoning in and out of me, deeper and harder. I writhed, but of course it didn't matter; the tentacle remained latched on to my pussy, forcing itself as deep as it could. I looked down to see the bulge sliding in and out of my tiny abdomen, forcing my passage wider than my own forearm would have. The sight brought me to another orgasm, overwhelmed tears streaming down my face and joining the slime as I moaned.

    The tentacle began to swell within me as it fucked my traitorously pleased hole. Orgasm after orgasm seemed to chain together, two becoming three becoming eight. I had never been one for multiple orgasms, but my body felt more... resilient. My mind was unchanged, however, and I eventually went limp and just stared at my abdomen, tears continuing to streak down my face. When it said mate, it just meant this, right? Ra'ito's beasts couldn't actually mate; they were sterile, right? I remembered something like that from the pamphlet. This one was just hungry. They fed on sexual energy, right? I couldn't remember, my mind was unfocused.

    I became more and more fearful as the tentacle swelled inside of me, forming a visible knot in my stomach, a bulge that it still forced deeper and deeper into me with each thrust. I shook my head as the tentacle in my mouth slithered into and out of my throat. I had just wanted to be taller. I had just wanted to be pretty. I shuddered as the knotted tentacle under the latch buzzed against my g-spot, straining violently against the mat of tendrils. A mass of blue glow squeezed its way towards my mouth, and the monster came down my throat.

    Its seed was hot, but it didn't burn. Nor was it disgusting; unlike the salty, bitter frat cum, this tasted like melted caramel sliding down my throat. Still, I choked and gagged as the tentacle and its seed took up the space I needed for air. The orgasm lasted for a solid half-minute, the sweet cum injected into my stomach until I was stuffed with the shit and nearly blacking out from lack of air. My eyes rolled back in my head as the knotted tentacle below surged inwards once more, the flat head pressing hard against my cervix. It remained there as the whole cock-head swelled. The pressure inside of me was intense, the tentacle one giant knot filling my cunt.

    I swore into the tentacle latched over my mouth, but the gag swallowed the sound. The tentacle began to pulse like a dick, stiffening and swelling like a heartbeat. I struggled wildly, my mind full of white-hot horror. Then the first blast struck. I went limp as what felt like a full liter of cum blasted into my body in one spurt. My abdomen bulged as my pussy briefly attempted to accommodatethe liquid, sending it out around the knot, but there wasn't enough room. When the second load—no smaller than the first—struck, it began leaking through my cervix. Once the valve was open, the womb provided no resistance. I shouted soundlessly as I came myself, and load after load of sticky seed streamed into my womb.
    The latch on my face withdrew as the aftershocks sent a few more ounces of cum inside of me. Something tickled against my cervix and I felt it go tight, sealing the torrent inside of me. As I rode out the last of my high, I realized that the bed no longer glowed. The light wasn't gone, though. I twisted my head down, finding my stomach swollen with literal gallons of cum, glowing blue through my flesh. My mouth hung open as the knot deflated, withdrawing the latch tentacles with a pop. A stream of blue seed still shot from each tentacle, launching ropes of the crud across my slime-coated body. A puddle formed around my ass where the bits that had escaped my womb pre-sealing ran from my body.

    "You fucking shithead," I panted. "Ra'ito is going to put you down for this. You can't disobey me like that. I read the pamphlet; pets have to obey their masters."

    The mat retracted and my bed shifted before me. In a moment, the blob towered over me again. After cumming in and on me, the rot had faded, leaving a clean white smile grinning wolfishly at me from a demonic, shadowy face. I propped myself up, sliding back into the corner and wrapping my arms around my heavy, glowing belly. My limbs were weak, my knees shaking from the aftershocks of several intense orgasms. I glared petulantly at the beast.

    "You're right," he rumbled. "And I think you'll make an excellent pet."
