Halloween party

“Pretty cool huh?” Ivan chuckles from behind his mask as he does a few iconic poses in front of you. The loud music and chatter at your friend’s Halloween house party makes conversation basically impossible unless you’re shouting at each other or doing weird hand gestures like your friend. His spiderman costume looks well designed unlike your spandex version of the black symbiote suit. “Oh! Meet my uni friends, Angelia and Chrissy” he says, introducing you to two girls dressed in a maid uniform and a nun. As a social butterfly, Ivan invited as many friends he could fit in his house as you peer over a crowd of people in the living room in costumes ranging from Toy Story characters to slutty zombie nurses.

“Try out the cursed potion cauldron” Ivan says dramatically as he leads you to a huge bowl of fruit punch with silver cardboard stuck to the side resembling metal. Shrugging your shoulders, you take a scoop and swallow an entire mouthful of the sweet and fruity beverage as other people line up for some too. A little awkward around so many people, you stand near a corner and watch the party continue as Ivan raises a toast with everyone. “To an unforgettable night of fun!” he shouts as everyone cheers and the music blasts louder.

After a while, you start to feel faint and you lean against the wall for support as you notice a few other people groaning about the same symptoms. Moving past people to get out for some fresh air, you hear a girl scream in horror nearby and you glance over to see her clutching her hand. Everyone stares at her in confusion as she starts to shrink, and her face looks increasingly glossy. “I… I can’t feel my hand!” she squeals in a panic as you notice her fingers fusing together and turning fluorescent yellow. In a Lego costume, her movements become increasingly rigid and her fearful facial expression twists into a forced smile. “H-Help… everything feels… c-cold” she splutters before her mouth stiffens shut and her entire body hardens into a lifeless plastic. Too shocked to react, everyone stares at the Lego figurine shrinking into its normal size and clattering to the floor.

“What the fuck?!” someone shouts in the crowd as everyone begins to panic. People start to scream as they notice changes spreading through their bodies and you quickly pat yourself down to check for anything. Looking around the room, you notice fur growing on people while others touch their face in horror as it shifts underneath. “Help me!” a girl squeals as you rush over to see Angelia from before in her nun costume, but her clothing is so much more revealing, and her breasts bursts out into D-cups. Her blonde hair remains the same, but you notice her Caucasian face becoming increasingly Asian as she explores her new body in confusion.

Realizing that the main door exit is blocked by all the panicking people, you turn around and look for an alternative way out. Jumping over a lifeless toy figurine of Woody and Buzz, you hear your hips crack loudly with a bone splintering snap as they explode out into child-bearing proportions. “Nnngh…” you grunt, feeling your hips expanding wider with fat as your belly gurgles loudly. Distracted by all the groaning and transforming people, you don’t notice your stomach flattening into an athletic toned core with a narrower waist to form an hour-glass figure. Recognising a maid costume in the distance, you rush up to the girl with her back turned to you and tap her shoulder for help. “Chrissy! Are you okay?!” You splutter as the girl turns around in surprise holding a duster.

“何を言ったか分かりません [I don’t understand what you said]” she replies in fluent Japanese as she glances at you with her cute Asian face. There’s no doubt she’s Chrissy from before, with the same pigtails and uniform, but she looks much sluttier with her pussy completely visible and her breasts pushing against her frilly clothes. “Spi… Spider-man?” she asks in a thick Japanese accent in confusion as she considers resuming her cleaning duties for her master to praise her.

“D-Don’t bother… she no… remember you” a recognisable voice shouts nearby as you turn around to see Ivan sitting on the floor in his spiderman suit. But as your eyes trail down, you notice a huge pair of soft D-cups hanging from his chest, clearly too large to fit in his costume. Glancing at him for a second time, you notice his crotch completely flat and his body much smaller than before as cum drips out of his suit. “これは外せない [I can’t take this off]” he splutters in a girly voice and fluent Japanese as he fumbles with the spiderman mask.

After a few seconds he finally pulls it off and your jaw drops to see a cute Asian girl with light brown hair staring back. Her lips pouts and she fixed the bangs over her forehead as she looks up at you in confusion. She looks completely unrecognisable from the Ivan you knew since childhood as she curiously gropes her breasts and glides her hand over her crotch. “あなたも変わっていきます [You’re changing too]” she says as her petite body shivers from her newfound spider sense.

“Huh? What did you sa---” you splutter, hearing your voice cracking higher into a sultry and feminine tone with a thickening Japanese accent too. Covering your mouth in shock your lips plump up while your neck become slimmer without your Adams apple. Trying to clear your throat, your face tingles as you feel your jawline softening and cheekbones popping higher from within the mask. “No… No… It can’t be happening!” you squeal in a panic, as your nose crunches narrower and your eyes widen with a distinctive slant and dark brown irises. Your scalp itches as your short hair doubles in volume and length and bunches up at the top of your mask as it feels increasingly uncomfortable.

Trying to find the zip and tear your mask off, your fingers twitches as they become slimmer with longer nails while your hand shrinks. Becoming frustrated, you fiddle with the cheap material more as your wrists become narrower and your biceps melt into a thin layer of feminine fat still brimming with the strength to hold back an entire subway train. “Why… it no… work?!” you groan in broken English as your broad shoulders crunch narrower and rounder while your ribs contract into a smaller frame.

Finally gripping the elusive zip, you tear your mask off and feel your dark brown hair cascade over your shoulders. Glancing at the mirror, your jaw drops to see a sexy Asian face staring back with no resemblance to your previous one. You begin to wonder how your friends and family will react or even recognize you, but your thoughts are disrupted by a faint pulsating sensation on your chest. Looking down in horror, you realize what’s about to happen as you peel the spandex suit further down to see your nipples already puffy with dark areolas. “B-Boobies?!” you gasp as waves of fat accumulates under your nipples and push them out into budding A-cups. Groaning, you feel your skin stretching to contain the sudden influx of fat as your breasts slowly expand into modest C-cups. Suppressing a moan, you feel them finally ballooning into heavy D-cups hanging from your chest and jiggling with every breath. “とても大きい [So big]” you mumble in fluent Japanese as you cup your tits in your hand and feel your fingers sinking into the soft and milky flesh.

Before you have time to explore your new breasts, a strange sensation emanates from your ass as fat moves through your wide hips to your lower body. “Nughh… me… no want… girl” you groan as your ass rapidly expand with fat until it protrudes out from behind as a bubble butt. Making use of your girthy hips, they continue to swell larger until the material around your ass becomes stretched to its limits. Your back arches sharply and with a few cracks, it becomes curvier and shorter to compliment your petite height and the natural sway of your wide hips. “H-Help… me…” you whimper in fear as your entire body tingles and all your bodily hair disappears, leaving your skin smooth and sensitive with a creamy oriental hue.

“Why… me girl Spiderman?” Ivan asks in her feminine voice as she touches her crotch again and feels her breasts jiggle. Closing her eyes, she tries to think clearly within her hazy and whirling thoughts as she vaguely remembers swinging on webs through the city to chase a bank heist. The sound of glass shattering fills the house as a zombie bump into the bowl fruit punch and Ivan realizes the cause of the transformations. “Drink… change… us” Ivan says as she plans to make an antidote to reverse the changes with her enhanced skills, but the roar of a lizard catches her attention. Feeling a strong sense of duty to subdue the monster, she leaves you groaning on the floor and rushes out to save the city from danger. “後で私とチームを組んでください [team up with me later]” she shouts in Japanese before swinging away.

But you barely pay attention to Ivan said as you stare at your thighs pulsating with activity. Groaning, you feel another wave of fat rush into your thighs until they swell thicker than your head to match your equally wide hips and round ass. “Unnhh… me… no…” you mumble incoherently as your sensitive inner thighs rub against each other and feel the spandex chafe in between. Grunting, you feel your feet crunch smaller with dainty toes while your calves become slimmer while retaining the strength to jump across buildings and kick enemies unconscious. The thought of fighting for justice makes your heart beat faster and the rush of adrenaline makes your dick painfully erect. “Ahnn… so... horny…” you moan with your face flush with arousal as you stroke the outline of your dick pressing against the spandex suit.

“Mmm… やばい [feels so good]” you moan as you shamefully peel your suit further down to reveal your throbbing cock already oozing with pre-cum. Gripping your fingers around your dick and pumping it a few more times causes you to moan loudly as cum sprays out continuously until your balls become empty. Shrunken and useless, your balls slurp into your crotch and reform into fertile ovaries pumping estrogen throughout your body. “Ahhnn… cock… no cock…” you moan with your legs spread apart as your flaccid dick finally retracts and inverts into your crotch to leave a tight slit in its place. Before you can react, pink and moist folds push out from within as your vagina deepens with a tingling clitoris. Curiously brushing your finger across your pussy lips sends sparks of pleasure through your body as you bite your lower lip and resist the urge to plunge your entire hand inside.

Slowing standing up to regain you sense of direction, you hear the distant roar and clash of metal from Ivan’s fight with the monster and you feel the need to help her as a hero too. However, after a few seconds, you body tingles from your spider senses and something doesn’t feel right. “Wha--- arghh” you squeal as a dark matter suddenly covers your entire body and creeps up your face. Grimacing at the simple mistake of forgetting about the symbiote connected to your suit, you shudder as the dark matter slides into your open mouth and up your nostrils. Your eyes roll back as the alien organism starts to twist your memories and personality to its preferences and you feel your breasts expand into E-cups oozing with milk.

“Nghhaa… sooo… hornyyyyyy” you moan lustfully as your tongue grows longer and drips with saliva. Your sense of duty as a hero becomes corrupted into an insatiable desire for cock and cum filling up your pussy. A sultry smile spreads across your face as the only thought in your distorted mind is to have fun with your sexy Asian body. Seeing a pilot standing in the room looking confused, you easily swing to him and pin him to the floor with hunger in your eyes. “Me… want…” you slur into his ear as he shouts for help, but you know Ivan is busy with the lizard. Gripping the bottom of your suit, you rip it open to reveal your dripping pussy as you effortlessly tear off the man’s pants too.

“がまんして [Don’t cum yet]” you pant breathlessly as you straddle him between your thick thighs and lower yourself onto his rock-hard cock. The pilot grunts with pleasure as you start to gyrate your hips and grind your clitoris against his dick. Your heart races as you feel his cock slide deeper into you and your breasts bounces hypnotically in front of the man as you bounce on his dick. Expertly using your warm vaginal wall to squeeze his cock in all directions, the man blows his load within seconds and soaks your pussy with cum. Letting out a sigh of disappointment, you feel his cum drip down your thighs as he pulls out and you look around for someone else to satisfy you.

“I… save you” you giggle as you kick a zombie away from a man dressed as a chef. His face of gratitude turns to confusion as you lustfully gaze at his crotch and imagine it deep inside you. The house is filled with so many people to feast on as your stomach gurgles hungrily for more. “F-Fuck me…” you moan alluringly to him as your iron grip holds him down. Crime fighting can wait after a night of pleasure.
