When Popups Don't Lie

(content warning: this one gets a little weird!)

"Hah, babe, come and take a look at this."

Mason came up behind Bella, peering at her laptop over her shoulder. It was just a popup ad, but all it said, in plain black font, was make your wish come true.

"Hah, that's the weirdest popup I've ever seen. Three guesses what you'd wish for."

"Oh? You think you know me? Tell me, what would I wish for, daddy?"

"You'd wish for gigantic tits and a huge dick and balls of course, you little pervert."

"Nuh uh." She giggled and kissed his stubbly jaw, feeling herself growing a bit hard in her panties. "I wish I was a perfect futanari goddess and you were my perfect little slutty cocksleeve, that's what."

He laughed, kissing her back, then wrinkled his brow at the laptop screen. "Hey, that's weird, the ad changed." It now simply read Your wish has been granted. Mason shrugged, and headed back out of the room.

Bella looked down at herself, her flat chest, her narrow hips, and sighed. She could feel her cock throbbing against her little lace panties. One day she'd be able to afford the hormones and the surgery – or of course her wish could just come true.

She grunted, shifting uncomfortably. Her cock was still throbbing. She took some deep breaths, shifting again to try to take the pressure off it. "H-heh. Wow, you're very insistent tonight. Okay, let's sort you out..."

She flipped open another window on her laptop, navigating to her Tumblr dashboard, carefully curated to provide her with an endless stream of her favourite porn. Her left hand crept down between her legs, rubbing at the underside of her dick through the warm cotton, her breath catching in her throat.

"Ffft-mmm, this- wow, this feels really goooood..."

As a practised and experienced pervert, the sensations of masturbation were hardly a mystery to her, but for some reason she was feeling especially revved-up and sensitive at the moment – which was funny, because not a few minutes ago she hadn't been thinking about sex at all. Her breathing became heavy as moisture began to collect at the top of her panties. She didn't even have to look at the laptop any more, the erotic thrill buzzing through her body was more than enough fuel for her ministrations.

Normally while she was rubbing herself, her dick stopped throbbing. Now, though, it kept throbbing against her fingers, taking control away from her motions in a way she was entirely unused to. Her tongue lolled from her mouth, sweat beading on her forehead. It was almost as if her dick was demanding more sensation than she could give it just by rubbing the underside.

She quickly flipped her 5-inch length up over the waistband of her panties and then slid them down, grunting as her hand flew to wrap around the shaft and start to slowly pump. To her utter shock, it was still straining and throbbing, even as she tried to jerk it off. The combined pleasure of her autonomic spasms and the caress of her hand thudded up her spine.

"Oh g-gaawd, I... Guh... S-stoop..."

She bit her lip, chest heaving with exertion. "M-Mason! Quick-uuuggh- come here!"

He came bounding back to the door, a worried crease on his brow, which softened as he saw his girlfriend's situation. "Oh, is that all? I normally leave you alone when you jerk off, but if you want me to help out..."

Mason had never pictured himself in this situation before Bella. A few months ago, he'd been enticed by her soft red-sticked lips, her fair skin, her long legs... When she'd sheepishly revealed her secret to him, he'd been taken aback, but there was something about her that was compelling – even if not what he was used to looking for in a woman. He was slowly but surely coming to grips with Bella's biology, and had progressed to comfortably being able to give his girlfriend a handjob. Of course if he'd offered to help out every time Bella started stroking herself he'd end up with a repetitive strain injury – the girl did a lot of masturbating.

He watched Bella's hand pumping, glistening trails of precum sliding down her dainty fingers, and swallowed. It had been difficult getting used to her cock, but right now it was strangely appealing to him. He moved over and knelt down between her legs, dislodging her hand with his, slowly pumping. He noted how it throbbed savagely in his hand, each one accompanying a moan or whine from his girlfriend. He still couldn't take his eyes off it, licking his lips subconsciously.

Without warning he leaned forward and took her into his mouth, her eyes going wide as the heat of his mouth enveloped her shaft. She'd done this for him countless times, of course, and respected his reticence to reciprocate, but his eagerness combined with the bizarre sensitivity of her dick was mind-breaking.

There was the salty, musky taste he'd expected, but somehow it only made him want more. He ducked his head down until the tip of her dick hit the back of his throat, his brow wrinkling as he realised he wasn't gagging. Nothing was stopping him from feeling every inch of her cock inside him, and his need spurred him on until his lips kissed her pubic mound.

She throbbed again, hard, and Mason gurgled. He slid his mouth back up the length of her dick and off the tip, licking his lips. Bella moaned, humping her hips up.

"Nooo, Mason, please, keep going!"

"Bella, uh... Are you bigger?"

She squealed. "Mason, I don't have time for roleplaying, please!"

"N-no, Bella..." He swallowed, his eyes still focused on the precum beading at the tip of her dick, "I seriously think you're bigger."

She looked down, sweating and panting, and... Mason was right. It was difficult to tell, but she looked bigger. She wrapped her hand around it, and there was definitely more dick than there was before.

"I'm j-just really horny- ahh!" It throbbed again, but this time both of them were looking directly at it as it actually swelled as it throbbed – and didn't shrink back down.

"No, Bella, Jesus, you're actually growing!"

They both hung in silence for a moment (at least near-silence, aside from Bella's whines), before Mason couldn't resist any longer and plunged his face down on her cock again. If anything it felt even better to have her growing in his mouth, feeling her throbbing meat filling his face. He pumped his mouth around her a few times, moaning into the flesh of her shaft. He didn't even feel the need to stop for air.

Bella writhed, clutching the sheets and sweating. Each throb was lasting longer now, and she could actually feel the growth in Mason's mouth. The sensation had spread to her sack, as well, each surge of tightness accompanying what must have been her testicles swelling.

Mason couldn't deny he was having fun. Filling his mouth with her filled a need inside him he never knew he'd had. He ducked his head down right to the base, humming happily, and then pulled up, his lips slurping at the tip.

"Mmm, Mason, your cheek, it's... smooth..." Bella's brow wrinkled. "Mason, did you shave?"

He looked nonplussed for a moment, then brought his hand up to rub across his cheek. It was completely smooth. He hadn't shaved that morning, and until a few minutes ago he'd been sporting some stubble.

The pair looked in each other's eyes for a moment with a shared understanding that something was very wrong. Bella's cock throbbed hard, noticeably bigger and glistening with spit. Mason's eyes kept being drawn back to it, his mouth watering, before he couldn't resist any longer and dove his face back down onto its pulsing length.

It slid down to the back of his throat again and he actually moaned as pleasurable tingles spread from his neck, spreading throughout his body. It almost felt like Bella's growth was accelerating – his mouth starting to stretch around it.

Bella groaned and sweated, a hand running up through her hair as her hips writhed. Each tight stretch of her expanding cock reverberated through her groin like a mini-orgasm, one that kept going. Mason was becoming even tighter around her dick, but still sucking undaunted.

She looked down and gasped in shock, seeing the top of Mason's head where not only did his hair look a little shaggier, but at the bottom, there was a slowly expanding front of pale roots – new growth of silvery-white hair.

At the same time, she felt heat growing across her chest, accompanied by the same feeling of pulsing, surging tightness that filled her groin. Her hands flew to her chest, daring to hope at what was happening. Even over the pleasure of Mason's blowjob, she squealed in delight as she felt new flesh pulse against her hands.

"Mason, tits! I'm growing tii-oooh..."

Not only was she growing tits, she was growing incredibly pleasurable tits. Her fingers brushed across her pebble-hard nipples, sending a jolt of pleasure through her that made her cock lurch even harder. Mason moaned around it, still sucking as his scalp tingled and his hair crept down from his head.

Bella's new breasts surged forward, gathering weight by the second against her hands, no longer just buds but a respectable pair of small, perky tits nestled under her top. They were soft and warm to the touch but still felt tight and full. She giggled, high on the sheer fantasy of what was happening to her.

"God, Mason, I'm... uhhh... This feels so good... I'm... I'm chaaaanging..."

Mason acknowledged this, but couldn't focus on anything but the thickening shaft in his mouth. Far beyond filling him, it was stretching out his throat, growing by the second – if anything growing even faster than before. He pulled back and found himself still speared on it, his eyes going wide as he had to shuffle backwards for it to finally leave his mouth, a string of drool trailing from the tip to his lips.

The sensation of it sliding out of his stretched throat made him moan, and that made him stop in shock. What rolled from his mouth was, instead of the deep, throaty tones he was used to, a distinctly high, light moan. He touched his neck for a moment, then looked up into Bella's eyes – still distracted by the stem of her cock bobbing between them.

"Bella, my- aah!" It wasn't just his moans – his voice was higher. He scrambled up off the bed, his eyes still occasionally flicking to her glistening shaft, and ran in front of Bella's mirror.

He was tiny. Enthralled by Bella's dick, he hadn't noticed his body shrinking away. No wonder she'd felt so big in his mouth – he was approaching half a foot shorter and thirty pounds lighter. His hair was down past his ears in a silvery tide, and his clothes billowed around his body.

"Wh-what the fuck?!" He turned back to Bella, who was grinning happily, playing with her swelling tits, her cock bobbing up between her legs. If not for the eleven inches of bobbing dick and balls the size of hen's eggs, it would have been impossible to tell her body was ever anything but naturally female. Not only had her new breasts reached a C cup, her hips had also widened and swollen out, gently curving away from her waist.

Initially, Mason's eyes trailed along the new womanly curves of her body, the jiggling as she groped her new breasts, but he soon found them drawn back to the throbbing length of her cock. Bella's eyes followed his gaze and she smiled, biting her lower lip and rocking her hips from side to side to make her cock swing pendulously. Mason's eyes followed it subconsciously.

"See something you like, honey?" She giggled, watching Mason actually drool as he watched her cock swing.

"Y-yes... It's... It's so amazing... Why can't I stop looking at it? I n-need it in my mouth..."

"I'm liking this new you. I've wanted this for so long. You to want me like this. It's everything I've wished fo-"

They caught each other's eyes. "The wish!"

The shock was enough to bring Bella out of her pleasurable stupor, reaching for her laptop. As she leaned forward, she felt the weight of her new breasts shift, and the tight ache through her hips.

The popup was still there: Your wish has been granted. "I... This is unbelievable! A wish-granting popup ad?"

She yelped as she felt her breasts surge with growth, matched by a hiss from Mason. Mason felt like his whole body was being squeezed, like he was being shrink-wrapped in his own skin – and the only thing he was feeling equal to the pressure of slowly shrinking was the throbbing need in the back of his mind to get Bella's cock back in his mouth.

"C-can we stop it?" Mason blushed at the ratcheting pitch of his voice. "Close the tab? Refresh it?"

Bella's mouth curled into a smile. "Stop it? Why would I want to do that?"

Mason's mouth dropped open, struggling to form words. "Because I... You... Look at me!"

"Mmm, I am." She pushed her laptop aside and lifted her tits up. They already filled her palms. "You look amazing. You're so small and delicate and adorable..."

Her cock bobbed between them, Bella focused on Mason with hungry eyes. "You heard the wish. You're turning into my perfect cocksleeve. That's why you can't take your eyes off my dick. Cocksleeves want dick, all the time. They want to please their futa goddesses..."

She groaned, her tits swelling larger by the second. One hand dropped away from her breasts to wrap around her growing shaft – only partially, since it was already too thick for her fingers to meet around it. "I'm going to be your huge, thick-dicked goddess. Look at it! It's over a foot long and it's still growing!"

Mason's mouth still drooped open, his eyes fixed on the massive shaft throbbing in front of him. His mouth felt wet, and he realised a string of drool was making its way down his chin. Bella edged forward, grunting as she attempted to pick her legs around the hefty mass of scrotum between them. Each testicle was roughly the size of a grapefruit, and lay heavily as they rolled around loosely in her expanded sack.

She ended up having to grab and lift it, shuffling her growing rear across the bed until she could swing her legs down the side and stand up, groaning. Her balls dropped pendulously and her enormous, swelling cock swung up and down, along with an unfamiliar jiggle across her chest as her new breasts fell into teardrops.

Mason stepped back in shock, not just at the extent of the transformation of his girlfriend's figure, but how much taller she was than him. He hadn't just been shrinking – she'd been growing, too. She stepped a long, curvaceous leg out in front of her, looking down at him over the bridge of her nose from now unquestionably feminine face.

Mason realised something was wrong. It wasn't that her new figure equally intimidated and excited him, it was that despite it exciting him, he couldn't feel something he was normally feeling. He looked down and gasped – no, squeaked – as he saw that his cock was flaccid, and tiny. He held it between thumb and forefinger, staring, before looking back up to be greeted by the immense, still-growing shaft of his girlfriend's cock.

"Aw, you miss your friend? Sorry sweetie, but he won't be around much longer. Don't worry though, I have a new friend for you!"

She gripped her dick by the bottom and lifted up until she could bump the side against the side of Mason's cheek. It carried a surprising amount of momentum – Mason could see it was already beginning to become unwieldy, carrying itself with a weight and leverage beyond Bella's new body. Mason looked up at Bella with a pout as the tremendous cock gently bumped against the side of her face.

"Don't give me that bratty little look. I know you want this." Bella reached down, cradling Mason's smooth, small chin, grinning as she gently pushed his face against her dick. Mason whined, his lips pursed and glistening with spit, eyes starting to roll back in his head.

"Go on, baby, just do what you know you want to do. Before you know it you'll barely even remember you had a dick."

Her cock throbbed, making her close her eyes and moan. She'd been continuing to grow and swell, just as Mason continued to shrink. He couldn't tell how far, since his only point of reference was Bella, but there was approaching two feet of difference between them. She towered over him, sneering at him above the vast shadow of her dick, and simultaneously he felt his legs quiver and his mouth water.

"B-bella... You're too big for me, now..."

She snickered. "We'll see about that."

Before he knew what was happening Bella grabbed the back of his head, pushing his mouth against the underside of the head of her cock, now two feet long and as twice as wide around as Bella's wrist. The heavy glans was the size of a honeydew melon. Mason choked, his eyes going wide as he felt his lips actually stretching around the shaft like rubber bands, and then suddenly the pleasure hit him.

His lips being stretched apart sent a pulse of pure, unadulterated sensation down his spine and between his legs, making his eyes roll back as his face expanded around the massive cockhead. Bella groaned, grabbing and pulling harder to slip the whole head of her dick past his lips. It was a bizarre sight, his shrunken jaw distending to fit the girth, but it stoked something primal inside Bella.

She grabbed the sides of his head and pulled, pushing the tip of her dick even further inside him. He made a sound halfway between a choke and a muffled moan and his throat began to expand, allowing her cock further passage.

Mason could feel shifting and gurgling from down in his body. It was almost like something inside him was slipping out of the way to make room for the cock being forced down his throat – and indeed, when Bella pushed again and forced the tip of her cock down past his throat and down into his body he realised that was definitely the case.

Bella didn't stop, shuddering in pleasure, until she felt Mason's lips bump against her pubic mound. She'd been growing as she forced her way inside him, at the same time he'd still been shrinking, and now his face looked tiny stretched around her huge, meaty dick.

An unknown instinct took him over, and he reached down to grab the edge of the bed, sliding back and leaving a trail of drool along Bella's dick, shaking as it rubbed against his insides all the way up to halfway along. After a shrug of his shoulders and a brief pause, he pulled, plunging himself back down on it.

He would have screamed if he could, but he could do nothing but make muffled protestations as he felt his entire body spreading apart to accept the enormous, unnatural intruder. He expected some sort of resistance partway as it encountered things that were not his throat, but it was as if his entire body had reshaped to be nothing but a fuck-tunnel. Dimly, he realised that was probably just another aspect of Bella's wish.

He fucked her, not just with his mouth but with half of his body, grunting as he pushed and pulled himself along her cock, taking some semblance of control. Heat spread through his body as he did, concentrating in his chest and down between his legs.

He thrust forward and Bella's hefty sack bounced forward, the top bumping against his chin. He gurgled, eyes rolling, as the heat built up even more, followed by a horrible pressure behind his nipples, and a hollow feeling in his groin. He knew what was happening, but he couldn't stop himself from continuing to fuck Bella with his throat, driving himself on to make her cum.

Her cock reached down to his stomach – or at least where his stomach should have been. He had no idea what was there now. Bella reached underneath his body to grasp at his nipples, making him shudder along her pole.

"Mmph... Are these all sensitive now? Can you feel what's happening underneath them? I'm – ugh – looking forward to getting a good look at them..."

She huffed, her face red with exertion. She was clearly working hard to try and keep herself in control as Mason's slick innards slid along her new, sensitive length, but after the sensations of growth and the blowjob she'd been receiving she was right on the edge.

It took less than another minute of spearing Mason on her cock before she gasped, her legs trembling and stomach muscles contracting, and felt a surge of pressure from the pit of her stomach and her pendulous scrotum. It built for a few seconds of hollow, brain-boggling pleasure before her muscles tightened even further, and thick fluid surged up the length of her dick and burst inside Mason.

The flood of hot cum stimulated every inch of Mason's insides, a hot buzzing wherever he could feel it that sent bolts of pleasure to every part of him. Within seconds of Bella's first shot Mason was hit by a full-body orgasm. His arms flailed, his eyes wide as his throat attempted to scream, completely muffled by the tight seal of his stretched lips around the thick cock impaling his shrinking body.

Bella howled, pumping shot after shot into her transformed boyfriend. It was almost too much – she was out of control and couldn't stop cumming. It was as if her new balls were inexhaustible, and the start of her orgasm hadn't just been letting the pressure off but had opened the floodgates.

She fell back onto the bed, tearing up with the continued effort of shooting, losing control of her body as her cock seized up again, feeling the huge load of cum slide up every inch of her enlarged pole. Mason's eyes went wide as he felt himself lifted up into the air, so small and slight that the leverage of Bella's expanded body was enough to carry him upwards before the cumload burst into his body.

She kept shooting, and he groaned internally as he felt pressure in his belly before his orgasm redoubled. His flailing hands contacted his midsection, taut and swelling with the endless volume of spunk being pumped inside him. A strange sensation on his sensitive nipples made him slide his hands further up, bringing the shocking realisation that they were swinging – topping two small but noticeable mounds of flesh.

Bella came for easily another thirty seconds, leaving Mason flailing, expanding, and cumming over and over again. Grunting, sweating and tearing up, Bella leaned forward, grimacing at the burn through her abdomen, and pushed on Mason's shoulders, sliding him off her cock. He couldn't do anything but fall back on the floor with a thud, his belly sloshing and new breasts swaying and jiggling. He felt his lips shrink back to their normal size, leaving no evidence of the violation he'd just undergone.

Silence fell over the room for a moment, but both members of the couple realised that the bizarre tingling and heat hadn't stopped, even after their titanic orgasms. Blessedly, the tightness throughout Mason's body had stopped, and not a moment too soon. He was tiny; he wanted to get up and look in the mirror, but his impossibly skinny legs couldn't hold up the four gallons of spunk sloshing behind his taut, round belly. As it was, he could barely just push himself around the floor as the heat built to burning in his new breasts, which slowly swelled before his eyes.

Bella, meanwhile, was staring transfixed at her penis. It had packed on an extra foot of length during its journey down Mason's throat, and was half again as thick as it was before. Its weight was immense, barely even throbbing, Bella's groin muscles straining just to keep it upright. She felt a pulse of tightness through them, a flash of the transformative heat, and suddenly the strain faded away.

She shuffled forward on her expanded rump and stood up, marvelling at how easily she was able to stand – and how much taller she was now. Her penis still swung and bobbed, pulling her hips along with it, and her balls dropped down, bouncing off the bottom of her thighs.

It was beyond just the physical sensations. The feeling of being so big, of there being so much of her and it all being her beautiful dick and balls, was an unmatched lusty high. She was so used to being small, to feeling out of place in her own body, and now finally she had – no, she was – everything she'd ever wanted.

She put her hands on her hips, watching her enormous cock bob in front of her. She shifted a leg, gasping as she felt her balls bounce off her thigh and jostle in their sack. Mason cowered beneath her, barely able to drag his distended stomach around, his growing breasts swaying above its pale dome. Silver-white hair fell down to his ass, brushing the floor. Bella looked down at him with a broad grin.

"You're so cute! Oh my god, look at you, you're tiny! Well, um. Most of you is tiny."

Mason looked up to reply and burped lightly, clapping his hand over his mouth to keep in a glob of spunk. Bella crouched down in front of him, her cock bumping against the top of his head, and pulled the mass of his belly up to get a look between his legs.

She squealed happily. "Mason, you have a pussy!" She pushed him onto his back, his breasts sliding up his chest to bump against the bottom of his chin, his stomach standing up proudly, and spread his willowy legs. "Oh my god it's adorable! It's all smooth... I wonder..."

Mason's eyes went wide and he gasped as Bella's fingers probed his new pussy, two sliding in as her thumb pressed down on his clitoris. "Hah, it's tiny, but it took me no effort to get my fingers in. I bet I could-"

Bella grinned as she pushed her entire hand into Mason. Just like his lips had, he felt his vulva stretch, buzzing pleasure straight up his spine and making him moan. Bella licked her lips appreciatively, watching Mason writhe on the end of her hand.

As she explored his folds and inner depths, Bella watched with interest as his stomach started to shrink down, his body processing away her cumload, while his breasts surged forward with the same urgency. They were already larger than his head, topped with huge, glistening pink pebbly nipples.

Pushing her cock to one side, she leaned forward and took one of them into her mouth, sucking hard at it as the mass of her dick rested against Mason's taut, smooth stomach and pillowy breast. It occurred to her that if she got any bigger, intimate sex like this was going to get very inconvenient – unless Mason literally laid back along her dick.

Mason howled in a high, almost squeaky register, his tiny body thrashing as Bella manipulated it with glee. He looked to the side, eyes wide with shock, and fell onto the massive shaft resting against his body. His mouth immediately started to water again, but this time it was accompanied by a small flood of moisture from his vagina. His arm reached up to wrap around it, cradling it to bring it closer to his face where he could start to kiss and nuzzle it.

A few minutes of play later, Mason's stomach had receded back to flatness, and his breasts had swollen to the point where he would barely have been able to cradle them in his arms. Bella stepped back onto her feet, groaning slightly as she realised her cock had gotten even bigger and heavier as she'd played with her new toy. Her balls were starting to impede how her legs moved and how she stood.

"You know what it's time for now, baby..."

He tried to object. He tried to refuse. The moment his eyes met the gigantic, glistening head of her perfect cock, the moment he felt his new feminine folds quiver and moisten at the sight of its thick four-foot length, any ability to say no washed away leaving only his unbearable need to have her inside him. He pushed himself back, the shrunken muscles in his painfully thin arms straining to shift the weight of his enormous breasts, and spread his thighs.

"P-please, Bella. Fuck me."

He was expecting Bella to take him then and there, but instead she bent down to grab him. Her cock squeezed up between the two of them, sinking into the cleft between his breasts and pushing against his petite face, leaving a thick smear of precum down his cheek that made his pussy squirt lightly.

She grunted, taking the weight of his chest into her arms, and lifted him up, holding him against the shaft of her cock which now extended up along her body. Their eyes met around its girth, the lust and need for it eating away at what was left of Mason's composure.

Bella grinned, sliding Mason up and down lightly, fucking herself with his cleavage, the shaft of her dick rubbing against his face. His breasts dominated his entire form, large enough now that their lowest points would have brushed the tops of his thighs when sitting.

She turned around and dropped Mason onto the bed, laughing as his breasts bounced out of control, sliding back down to slap him in the face before their gelatinous mass slid back down his body like a tidal wave of flesh and then to either side of his skinny chest.

Before he could gather himself, she gripped her cock by either side of the shaft, manoeuvring it into position between Mason's thighs. It was almost comical – the enormous penis was rapidly approaching the width of Mason's hips, and the slit at the tip of the basketball-sized glans was nearly as large as the little bald pussy it kissed.

It occurred to Bella that she couldn't reach to the end of her dick to grip Mason and force him down onto her length. However, the moment she pushed lightly against his vulva, it was as if he became immobile, allowing her to simply push forward and start to insert herself inside him.

She watched in rapt excitement as it seemed like his entire body expanded to start accepting her girth. He howled as his pussy lips spread apart, just tight enough to require Bella to push but elastic enough to keep expanding.

Mason's legs kicked uselessly either side of the enormous intruder, starting to splay as not just his vulva but his entire pelvis began to expand to either side. The feeling of stretching was hammering his brain with pleasure and so much more of him was stretching now. Bella's cock reached his stomach, or whatever lay under his midriff now, and his skin shrink-wrapped down onto the shape of her dick, revealing the shape of the glans, the ridge where it met the shaft. His breasts shook like jelly, shaking back up to slap him in the face each time Bella thrust forward.

She pushed far enough inside him to grab him by the ankles, the unnatural anchoring effect fading to be replaced with pulling him back down onto her cock by his legs. She pushed deeper and deeper, revealing how much of Mason's body was no longer human inside. Without any discomfort, solely with the almost unbearable pleasure of continuing to be stretched apart, Bella's cock advanced past the top of his stomach, bulging between his breasts. It didn't even stop when it reached his neck, and his eyes went wide as he made a choking noise, his throat stretching out around it.

He vaguely slapped at his neck, trying to move but utterly helplessly impaled on the hyper-sized penis. Another thrust from Bella made his jaw start to expand. With one final, sweaty thrust and a deep grunt, in the same way that Mason's mouth had expanded to take her cock on its first journey, his lips spread open, his mouth gaping to reveal the tip of Bella's cock.

Bella stopped, chest heaving, staring wide-eyed at her boyfriend's tiny, feminine body stretched around her cock. He struggled faintly, but couldn't move, only able to roll his eyes from the pleasure of being fucked all the way through.

"M-Mason... Oh-ohh, my god... You're a cocksleeve! You're my cocksleeve!"

Her face broke out into a massive grin as Mason's eyes tried to follow her. She pulled back, easily lifting Mason's body with the leverage of her dick. She stood bow-legged to allow her balls to swing between her legs, level with her ankles, Mason's arms, legs and massive breasts bouncing out of control as her dick swung to and fro.

She turned around, her enormous ass coming down onto the bed with a thump, her dick standing tall. She grabbed Mason's hips and pulled, sliding his entire body down her cock until his pussy collided with her groin, a full two feet of cock projecting from Mason's distended mouth.

She stared at his helpless body, his enormous jostling breasts and the slick sheen of juices he'd left down her unnatural new appendage, and after just a moment of processing, grabbed him by his waist and started to fuck herself with his body.

His body rubbed and caressed every inch of her dick as she pumped him up and down her length, especially after the fifth or sixth thrust after which he started to cum explosively, his whole body jerking and his insides writhing around Bella's dick.

His orgasm hadn't even subsided before the next began, his pussy twitching madly, juice trying to squirt out around the tight seal of Bella's dick. Every half-dozen journeys up and down the five-foot length of Bella's penis brought with it a redoubled orgasm until finally, eyes rolling, unable to even scream, tiny arms desperately trying to hold onto his bouncing tits, he passed out.

Bella didn't notice, continuing to jerk herself off with her boyfriend's mutated body, sweating and grunting as her enormous balls churned with another massive load of spunk. If Mason was utterly helpless before her new size and equipment, then Bella was helpless before the new instincts and needs swirling in her mind.

She was completely in control of her actions, but she didn't want to stop. Every time she even slightly slowed down, her nuts would growl, her cock would lurch and belch out a load of precum and the aching need to shoot off built even further.

She reamed Mason's helpless body for the next few minutes, red-faced and glistening, her entire enormous body tensed with the growing sensation of orgasm. Suddenly her eyes went wide. She heard her balls gurgle as her abdominals began to tighten, sensation shooting up the length of her cock as it pulsed.

If she had still had her previous body, she would already have cum by now, but her hyper-sized assets were only just starting to wind up.

Her hands fell away from Mason's waist, bracing herself on the bed as her body throbbed and tensed, her testicles aching and churning. It was like all the strength was being sapped from her body to prepare it for her impending orgasm.

The sensation was like being edged, kept just on the cusp of shooting, but suffused through her whole body and going on for much, much longer. She panted and groaned, trying to flex her muscles to force it to happen faster but to no avail.

A moan started to roll from her mouth, morphing partway into a scream as her muscles clamped down and pushed the first gigantic blast of cum from her cock. The whole shaft lurched hard, actually pushing her back and sliding her ass along the bed from the leverage, the sound of the massive load of fluid actually audible throughout the room. Mason swayed on her cock, eyes rolling in stupor, arms and tits bouncing.

Bella's first cumshot alone was nearly five seconds of constant high-pressure ejaculation, a massive flood of thick pearly jizz flying from the end of her dick and sailing across the room. It hit her dresser mirror and slopped down across the top, carrying her makeup and tchotchkes to the floor in a tidal wave of spunk.

There was a brief moment of peace as Bella's next shot built up, giving her just enough time to slump back and point her cock towards the ceiling before it started shooting again with a viscous gloosh. She squealed again, tearing up as her mind was assaulted with the raw, burning sensation of her new hyperorgasm.

It hit the ceiling and splattered, raining down across the couple in thick rivulets. Bella clutched her expanded breasts, gurgling in stupor through a glob of cum across her mouth while her body prepared its next multiple-second cumshot.

She laid on the bed, twitching as her enormous pole lurched and swung, legs spread to make room for her groaning, growling balls, helplessly basting herself in gallon after gallon of spunk. Her knees drew up alongside testicles bigger than beach balls, hips writhing in a thick, warm puddle that grew in volume by the second.

Everything in her room carried at least a glob of cum, and everything in front of her was completely coated. Ropes of it dripped like stalactites from the ceiling. It bubbled on her glazed, slack face, glistened on her tits and pooled in the cleft between her thick thighs and huge scrotum. She wasn't in a position to measure, but she was shooting five gallons of cum with each titanic ejaculation, and four shots in she wasn't even close to done.

She gurgled, howled and screamed. Her fists flailed uselessly into the puddles of spunk on her bedspread as her body pulled from side to side with the motion of her dick as it continued to lurch and shoot. Eleven more extended, painstaking cumshots later, it finally stopped, enormous gobs of spunk just rolling from the end of her cock.

As her dick started to flag down, slowly shrinking, Mason's elasticated body started to slide up until his pussy came off the end with a pop, sending him tumbling down into a pool of spunk on the floor several inches thick.

Mason blinked, slowly stirring. His body felt strangely light and heavy, all at the same time. He was surrounded by damp, thick clamminess. He tingled all over, especially his lips, and...

His eyes flew open, his hands shooting down between his legs to confirm, yes, a tiny bald pussy still sat there. He realised his arms, slight and skinny, were dragging through an enormous, cooling pile of cum. He knew he should have been repulsed, but instead the smell was making his mouth water.

He tried to pick himself up, remembering too late the tremendous weight that had been added to his chest, and succeeding only in dunking himself face-first into more jizz, his tits jiggling and a small whine issuing from his mouth.

He heard giggling from behind him, and straining against his cumbersome tits and the thick piles of spunk, managed to turn over. He stared up at his seven-foot girlfriend, sitting on the edge of the bed with her massive nuts dangling over the side between her legs, the thick log of her flaccid dick laying across them. She was grinning wickedly down at her boyfriend.

"You look so cute like that, Mason."

He wiped his face, still salivating at the smell and feel of cum. "Did... Did we just..."

She giggled again. "Fuck you all the way through your body? Yup. Was it good for you?"

"It... It was..." His pussy twitched at the memory of the intense, unbearable pleasure as every inch of his four-foot-six frame was split apart by a cock bigger than he was. He confessed "It was unbelievable. I've never felt that good before in my life."

He looked down his arms, then hefted one of his breasts, biting his lip at the rush of sensitivity. "This is insane. What's happened to us? What's going to happen to us? I- I'm not just a girl, I'm a freak!"

Bella leaned forward, gripping Mason by his waist and lifting him up effortlessly. His own massive tits pressed into her own as she hugged him, cum squishing between the pair, Bella giving him a kiss on the top of his petite forehead.

"You're not a freak. You're beautiful. You're an exquisite little treasure." Mason felt himself relaxing at the same time as a rising heat began to kindle in his belly at the feeling of Bella's oversized body rubbing delicious-smelling cum into him.

"B-but my tits and your c-cock are bigger than I am... How will we find clothes or, or go outside, or-mmmph- function?"

His face flushed, his skinny thighs twitching as his pussy started to leak. Bella stroked his silver hair lightly, smiling.

"Do you trust me, Mason?"

He looked up into her eyes. Held in the air like this, it was obvious how helpless he was – that his tiny body was at the mercy of his seven-foot-tall goddess of a girlfriend. He could barely stand because of the weight of his tits, apparently even a touch was enough to start off his new libido, and his mind was fogging with the thoughts of Bella's giant dick and the cloying scent of her jizz surrounding him.

Could he even see another man without fantasising about him? Could he resist if his giant breasts were grabbed and groped, if a thick cock was pushed against his tiny cheek, if his pants were torn apart to make way for a gang-bang...

He whimpered, trying to force the images from his mind even as his pussy and throat flexed and writhed, desperate for something to fill them. His libido betrayed him. He looked back up at Bella. Even with his chest heaving as the fear of his new life started to take him over, he knew the answer.

"Yes. I trust you."

She smiled, stroking his cheek. She was having her own reactions to having Mason pressed against her, but they seemed slower to build than his. "Then we'll be fine, okay? I'll take care of you. I'll take care of everything. We don't have to worry about anything but enjoying this new gift, enjoying each other."

She let him drop, leaving his face mashed between her breasts, his legs straddling the huge, flaccid length of her dick. He whined, grinding his clitoris against it. He could feel a strange empty sensation – his pussy trying to open for it. He heard a gurgling noise from beneath his tiny ass, and his mouth watered at the thought of her building up another huge load of cum for him.

"Mmm, baby, I'm already starting to get hard again. I can feel it." She reached down under Mason, lifting up the thick slab of her cock, pushing it up against him. "It's so big, though, it'll take a long time to get fully hard. I don't think that should stop you, though?"

Mason slid down against it, reverentially sliding his breasts and cheek against it as he dropped to his knees. He grunted as he lifted the huge head, straining to push back her foreskin, and lapped at the stream of precum starting to ooze from the slit. He pushed forward and moaned as he felt his lips happily expand to start stuffing the floppy, spongy flesh into his mouth.

"Mmmm, yeah. I think I must have shot fifty gallons before, baby. Want to see how much your tummy can hold?"

Mason moaned again, the flaccid head starting to slip past the back of his mouth. His hands reached out to caress her gigantic testicles, feeling their warmth as they built up a titanic orgasm for him. He couldn't think of anything he wanted more.
