Jeff excited to see his perverse family crossed the hall to his mothers room. As expected she sat on her bed with her phone in hand and as soon as he crossed the threshold of her door way she pressed enter on her device and looked up at him with a devilish smile. Her body then began to bulge and pulse as her frame expanded all over with thick vains forming beneath her skin. Her muscles swelled under her cloths. The fabric popped and tore as she quickly reach professional body builder sizes and her top and bottom shredded like tissue paper under her expanding form.
She stood from the bed standing 8 feet tall, her head began to scrape te ceiling but not from her newly found height! No her skull was expanding upward and outwards almost disk-like. Her hair fell out of her scalp exposing thick ridges and vains as though the wrinkles of her brain were remolding her skull. From her brow emerged a dark carotin growth that quickly grew outward sweeping back and almost cradling her warped cranium like a boney circlet! To the left and right of her eyes the skin parted vertically revealing another set of eyes, these ones amber with predatory silted pupils and soon they grew twice their size to fit more in scale with the expanding head of Jeff's mother. Her throat then stretched longer before bulging just at her jaw. Jeff thought it was some kind of air sac like a toad or frog but it soon split wide open revealing a row of sharp teeth that soon formed a jaw underneath his mothers original mouth. The beast that stood before Jeff now towered over him easily 12 feet tall not including its warped head. its still growing body now taking a knee inside the cramped bedroom. It's thick arms began to massage the flat pectorals on its chest, his mothers breasts had been their when the changes started but the expanding muscles had pressed them flat against her bulk. Now the flesh bloomed again as a pair of breasts inflated atop the sculpted slab of her bosom. They rapidly reach medicine-ball size under her large hands and soon yoga ball which oddly seemed to match her broadening shoulders.
Janice now entered the room completely naked and non-too-disturbed by it or the hulking monster that was her mother, she came to stand next to Jeff as their mothers bulk filled the room now, the gargantuan biceps, massive shoulders, freakish head, and chiseled core bracing against the walls and ceiling, struggling for room as her over 20 foot tall frame began to crack the drywall and bend the boards that were the skeleton on their home.
"Ahhh, Janice your here too, good!" Cooed their mother unchanged voice from her original unchanged face set in the center of the monster face she'd sculpted for herself. "Be a dear an hand me my phone."
"Sure mom, you look great by the way!" Janice said, almost drooling as she looked up at her mothers new form. Janice bent down picking up the phone and placing it in her mother's outstretched hand.
"Thank you dear." She simply said as she began tapping away at the tiny phone in her huge hand, somehow deftly operating it with her oversized fingers. Jeff heard the familiar 'ding' of the apply button and grew a little worried when his mother's gaze fell upon him.
The first thing he noticed was the wet sensation on his bare chest as he must have been absentmindedly drooling from the spectacle of his mothers transformation. He took his arm and whipped his mouth clean. Except he didn't! It wasn't clean a thick viscus trail of drool traced up his arm and it felt good, really good! So good he didn't know how to describe it? It was a foreign sensation to him he placed his hand back over his mouth and lit up with sensation again! He then realized his lips felt wrong, better then they usually did, far more sensitive and very wet! The thing that was wrong though was their shape! They now split vertical up to his nose! Jeff being the expert pervert that he was knew instantly that his mouth had been transformed into a female vagina! Rather then freak out over this he went whole-sail into it.
He reached one hand to his new mouth dipping two fingers into his face pussy, hooking down to his jaw, feeling his tongue and realizing he could lick his inner walls, processing to do so! His other hand freely jerked off his erect cock, it was painfully stiff from watching his mother become a two faced monster and he'd been to enthralled to do so earlier.
He soon noticed other changes; firstly his tongue was retreating down his throat away from his sensitive entrance, second his mouth was growing bigger he felt his jaw soften like jelly until his mouth was just cardinal pleasure and muscle. He reached more fingers into his gaping maw as it swelled to consume his neck, the large labia dangling down to his collarbone and Jeff found himself fisting his basketball sized face pussy down into his sternum.
His lungs and hard were now just on the other side of his vaginal wall but they felt distant to Jeff as their automatic function seemed to dim or slow? Jeff hardly cared, his brain was sparking with so much stimulation! Even more so as he began to feel his arm thicken, stretching his lips further! He tried his best to see what was happening, his eyes rolled frantically from the female sensation of his face, but he could tell his arms weren't hulking out like his mother's had, growing thick with muscle n vains. His growth seemed proportional every part of his arm scaling up in size.
Size? He tried to look down he knew his neck was gone from his giant pussy maw that was the top of his torso but looking around he could see he was much taller now. It was a struggle to pull his hand from his new organ firstly if felt too good being filled bit he also noticed his huge elbow slammed into a wall, dent it easily between the studs.
More cracking happened around him as he could see the bulky form of his mother bracing her arms against the ceiling, planting her foot and one knee against the ground like an image of the Greek titan Altus holding the world up. With tremendous strength and visible ease she flexed her body, crushing the floor beneath her feet and peeling the roof off their house like it was a tin can lid!
The demolished floor and house swept Jeff out into their backyard and when he recovered he looked up at his fifty foot tall freak of a mother, stand proud and tall above the scrap wood that was once their house.
Jeff took himself in he was barely able to see that his form was far more bizarre! His arms had grown huge! Easily 15 feet long his body was mostly torso and he could see his waist. He felt around with his hands and found his legs finding them to be roughly the size they originally were, his hands me remarked however felt big enough to crush mini vans in his grip. Carefully he felt around for his cock feeling some sensation between his legs it was still there, but in his hands it was smaller then a grain of rice, maybe even smaller then a grain of sand.
Is distress was cemented though as he felt his tiny legs and microscopic cock whither into nothing-ness his shoulders grew stiff and his arms were forced into a forward orientation. He felt a sinking sensation in his stomach, until he realized it was just his stomach sinking as more of his shifting insides gave way to the presumed womb that now made up his internal organs.
He was barely able to process his new innards cohesion when he saw his arms changing! They were splayed out before him in the wreckage of his home and yard. His hands shifted and contorted, bones and muscles rearranging as his fingers scaled back in length, nails arching and curling into hooks that retracted into his knuckle. Fine hairs sprung up from his pores quickly carpeting his flesh in a blanket of white fur with black stripes! Soft pink pads swelled under his palms and continued to swell and inflate until they looked like squashed balloons beneath his obvious Bengal tiger paws. They were incredibly sensitive, he could feel each blade of grass beneath their colossal surface area, his senses were practically on fire.
He began to panic though when her tried to move the clumsy looking limbs and discovered his joints were locked in new positions! He could reach his face, which meant he could reach his pussy-maw! He flapped his labia in distress! The feminine organ gaping open and shut as he panicked to do anything at all!
"Shhh-shhh..." He heard from behind him "mommy's here little kitten."
Jeff's mother was somewhere behind him, in his fixed position he couldn't see at all, just the view of his arms-turned-tiger-forelegs. He did feel her hands on his shoulders soon after. Shoulders didn't feel like the right word for his body though, it was completely alien what he was now. He felt two flat, broad, surfaces next on either side of his 'head' then a hot surging rush that ran though his body! He saw his feline limbs surge in size as though they'ed just been injected with air like balloons and then they began to move?
He'd not moved them? They then launched upward as a great force then weight asserted itself above him, he watched his tiger claw toes stretch and flex, the actual claws retracting out to take and dig into the ground and wreckage of his former home, sections of wall and boards literally sliced under their movements. But Jeff hadn't willed it, he tried to bend his 'knee' or elbow, whatever it was now but nothing happened.
"My,my Jeff!" His mother cooed from above "your a very needy girl now hun? I can feel how much you ack for some relief..." Into view came the large, veiny, muscular hand of his transformed mother. Two thick fingers parted his fat gaping lips, not nearly enough to fill him but damn good to saite him and take his sex addled mined from the panic that was the realization he was now his freak mothers giant pussy and tiger legs.
Jeff was now the biggest part of his mother. Two 50 feet tiger legs and a pussy big enough to suck on a school bus and still be unsatisfied! The tiger body was 3/2 of her size, her slightly smaller body looking a little out of place, especially how she had to arch over to finger herself. Jeff's black hair formed a kind of belt around her waist where it collided with his tiger body. His small eyes were stationed just below that hairline inside his tiger fur, and his nose had now become bulbous clit not unlike a dome jungle-jim found in any common playground.
"Now where is your sister..." Jeff's mother remarked to no one. She'd rendered Jeff a prisoner in her own body, he couldn't reply, except for maybe winking 'HER' new pussy for her.
Phone still in hand she withdrew her other hand from her sopping wet nether-lips, wiping them off on her waist-mane-fur and skillfully putting in commands, selecting them for her daughter Janice and hitting apply.
Beneath a pile of rubble from their house Janice emerged lying on her back. Her mother didn't feel like sorting through mess so her first change was to simply make her daughter 20 feet tall so that she sun simply 'emerge' from the scraps of wood and drywall. Her growing mass was also healed of any wounds that had been inflicted by the collapse of their home, leaving her naked body pristine. She seemed to come to when she reached the proper height, brushing a few loose boards from her body and looking up at her transformed mother.
"Mom? What happened? Where's Jeff? Or Amber? What about our house?" Janice began to sputter until she looked around and realized she was so large compared to the mess of her home and giant mother. Neither seemed to care about the other people running from the neighborhood at the giant monsters that emerged from the exploded home.
"Not to worry dear, you'll join your brother soon enough, maybe your sister will join us after." Said Hellen from up-high. (I just remembered their mother had an established name)
Janice looked puzzled then saw the way her mother was teasing her giant clit and how her massive pussy lips quivered and winked and what her mother had just said. As she put two and two together like her mothers lower half and the absents of her brother...
"Oh that's fucking hot mom!" Janice announced! "Am I next? Am I going to merge with you?" She asked excitedly and clearly aroused! Looking up at her giant monster of a mother she started playing with one breast while her other hand teased her pussy.
Janice's skin began to darken and thicken becoming a thick, leathery, green hued, hide not unlike a reptile's. Her fingers became tipped with a thick claw as did her toes. Her spine began to project off her tailbone lengthening into a tail while her face grew out into a square reptilian snout, dull pointed teeth making up her maw. Her sexual coos and moans became closer to a alligator's bellow and hiss.
Her sounds became deep grumbles as she felt her arms changing next. Her shoulders squared up and muscles swelled. A mound of mass piled on her back as her trapezius exploded in size encasing her head like a hunched back! Her biceps grew longer and thicker, colliding with her bulging back. Most frustrating of all were her hands! Her palms became ridged and her fingers fattened and shrank, the thick nails taking up her first digits and her thumb receding up her arm as her wrist locked up becoming a new joint!
Janice fell forward as she became top heavy. something had changed in her legs as they'd lost strength but her newly changed arms caught her fall and Janice realized her arms had in fact become legs! Her large flat palmed hands now resembled dinosaur feet, her biceps the powerful thoughts and her back and shoulders the hips!
The changes continued out of view for Janice but she could feel something happening to her lower body. Her waist rapidly shrank while her ass grew larger. Her legs felt limp and weak. The limbs became soft as the ridged bones broke apart and reformed into smaller joints until her legs reformed as two separate tails. The mass of her rear end collided with her new thigh, her torso and waist consumed by the muscular expansion of her ass and thighs! In her rear two new openings appeared under her tails a thick black anuses bloomed at their bases! Pulsing vains could be seen on the muscular puckers looking more like monster truck tiers in a row between her sculpted mounds of ass flesh. She briefly registered her pussy sealing up and vanishing but more was happening to steal her focus.
Directly below her though Janice could see around her snout that her breasts had grown larger, now dangling between her once-elbows-now-knees. The realization that her body was now just a giant rear section of some dinosaur like a T-Rex settled in and exited her deeply she took a deliberate step forward with her big arms/legs and flattened the shed of her backward under her bulk, she could feel the snapping of posts and 2/4s like stepping on twigs in the forrest, the riding mower within crunched like a empty soda can under her weight!
The exerted display of strength was exhilarating and Janice felt an obsessive sense of pride welling up in her. Something was actually welling up in her, something in her changed anatomy felt off, she could feel something like her stomach churning below her, coming from her large hanging breasts, but more so she felt something choking her? She started to cough as her throat gave way to a foreign mass dislodging itself. With her legs stuck below her she could only gag as something emerged from the back of her mouth!
It was fleshy and solid, rippled with vains, it passed over her dulled teeth which seemed to massage it as it snaked out of her mouth! The object in question parted her long reptilian snout and came into view, it was round and fleshy and as it continued to grow, its end tipped with a ring that began to narrow making more of its length easier to spew out. The pick pulsing organ continued to slink out of her mouth like icing from a pastry bag, slowing only when another ring formed on its growing length. The appendage came to a halt finally and Janice struggled to breath with the gargantuan horse cock hanging from her mouth, she soon found she didn't need air somehow. There was however more in store for her she suddenly felt her jaw pop and another surge of growth from the base of the massive cock as a thick, canine like knot forced its way out of her throat, then another and another, all three staked directly behind each other like some exotic dildo advertised online.
This final growth send her stiff mouth cock bobbing and its length colliding with the street, cracking pavement and smashing a water hydrant which began to gush stimulating high pressure water onto the underside of the sensitive organ.
The weight and size of her new cock plus the cold water coating her burning hot massive cock, which created a sauna effect across half the neighborhood, left Janice pinned where she was. Helen took this opportunity to compleat her daughters change. Using her tiger legs she backed herself overtop the colossal horse-dragon hybrid cock. An extension of Jeff's lower abdomen grew out and quickly adhered to the pelvis of Janice's rear end, tiger stripes collided with dino-hide and the two fused into the taur body of their mother. Janice briefly recognized the loss of control over her limbs and tail, but could now feel the sensations of her mothers monstrous body and Jeff's cavernous pussy body, his sensitive paw pads and aching need to be filled! Jeff likewise felt the need of his sisters mouth cock and the pulsing ach of her puffy muscular asses!
Helen likewise felt all the sensations if her conjoined children, most of all her new cock! She couldn't reach it herself atop Jeff's legs, and she desperately NEEDED a release after all this build up. She took the minuscule phone in her hand, looking like a black grain of rice. She was grateful she had the foresight to program herself to always be able to use the phone as long as it was on her person. She made another edit to Jeff and then brought the speck of technology to her large second mouth and swallowed it for safe keeping.
Jeff felt something welling up inside him, grateful to be filled for once since being turned into the sexual abomination he now was! The growth violently ejected past his labia as a thick tendril of pick vaginal flesh withered about! It was ripped with cords of muscle and vains and reached as far as the humongous cock stretched from the back of their shared body which Jeff figured was the length of 2 football fields if he cared of such things. For now his focus was on that cock! He needed to feel it!
The pink muscle coiled around the length like a snake around its pray! Jeff found his new appendage was in fact a massively over muscled tongue! all three of them could feel the heat radiating off its thick shaft, taste is musky flavor, feel the rough tastebuds scraping the asphalt road, grass, water, and air around their body! With little work needed they all let out a roar from their respective mouths; Helen moaning with her unchanged human voice, her second mouth howling a deep roar, Jeff's pussy maw gushing fluid, Janice gagging a roar. From
Janice they all felt the sensation of vomiting as her breast-balls clenched and cum rocketed up her mouth shaft, some of it emerging from the gap of her thought to saturate her mouth! The cum erupted with such force the for three blocks before them houses were slit in two like a power washer though dirt! Earth was torn up and turned into a trench of hot steaming cum that cut though the suburbs! The orgasim was mind numbing for the three and the surrounding streets were flooded with cum as pulses jetted out with weaker pressure while the three collected themselves from the afterglow, even though Helen was all that really mattered, having subverted the control of their body from her children turned freakish sexual organs.
