(Two Weeks Earlier)
Sakura staggered home in the dead of night. She'd only just regained consciousness. The first thing she'd seen was Naruto sheathed in his four-tails chakra mode and dick-pounding Hinata into squirty screaming oblivion. An overdose of sex administered straight to her retinas. Too rich for her blood. …Or so she'd thought.
Part of her had still wanted it. Wanted to be where Hinata had been. Pinned helpless beneath a ravenous beast of a man. Made brutish by the lust she'd seeded in his cock. Primed and ravenous and eager to punish her for leading him on.
Sakura fought down those urges. They were insane. What they were doing was unnatural. It felt fundamentally wrong and yet so… so right~ Pleasure beyond anything humans were meant to feel. Closeness without borders. Freedom from shame and guilt. To be absurd in mind and body and still love oneself wholly. The dissolution of the self in an ocean of dopamine.
But she'd never experience such rapture. Her body wasn't cushioned enough. It wasn't flexible enough. He hadn't been able to fit it all inside her. And if he had, she would've split in half! And yet the thought didn't scare her nearly as much as it should have.
Hoo boy, she had to be absolutely blitzed if she was thinking like this. Thank god nobody was out this late. Because her clothes had been completely destroyed. Her meathead teammate had ripped her shorts and her panties to ribbons. So she was basically bottomless. Thankfully, she'd thought to wad up her dress and hold it to her pussy to hold back the overflow of semen inside her. Stupid Naruto and his stupid big balls.
Big kissable balls…
Gah! No! Stop that! Don't be stupid, girl! He'd break you!
A white globule oozed down her left thigh. Shaken free as she stumped along. It fell steaming to the sidewalk. And juging by the state of her tummy, there was plenty more where that came from. Sakura could feel his semen slosh inside her womb. Its heady umami beefiness clung to her tongue, aromatics tendrils filling her brain. She looked pregnant. A little, first trimester at most. But even such a small baby bump was enough to overshadow her meager breasts.
Even now Sakura couldn't get over her lack of heft upstairs. God dammit, she was a married woman and she was still an A-cup! Every time she went shopping for bras she still had to go to the kid's section. Today's number had teddy bears on it. Maybe it was the vodka, but she could swear their doleful little eyes were mocking her.
'Home' was her and Sasuke's house. They'd moved in together pretty much as soon as she'd asked Sasuke to marry her. He'd handled the expenses and she'd handled the house itself. Which was nice in theory. But in practice? Pretty much nothing like it. Sasuke was basically never home. And so when the sloped roof of their 'family' house peeked into view from around its suburban twins. Well, she wasn't exactly worried about being caught. Dimly she thought she should feel guilty for this whole cheating thing but… meh. What he didn't know wouldn't hurt him.
She let herself in with a key under the mat. Cool air from the central conditioning soothed her sweaty skin. The laundry room was right next to the front door. So she dumped her ruined clothes in there and set the machine for a deep, deep cleaning. Nude now she swayed upstairs, thick hips jiggling on every step. Yes, Sakura had a fantastic ass. A muscular inverted heart bulgy enough to necessitate her wearing thongs exclusively. But her desire for big tits ran deep. All those years of breast envy kept Sakura from appreciating her delicious posterior.
Big, soft, warm, bouncy boobies… Heavy on her chest and ruinous to her balance. Relentless rippers of bras and seeders of envy in women the world over. Humiliatingly huge hooters obese enough to strain the backs of the strongest female bondage sub. Doubled over on their knees with their whole arms devoted to corralling their Brobdingnagian bustline. Beg their mistress not to blow up their boobs any bigger~
Yet all her fantasies about excessively massive porno titties dispersed the moment she crested the stairs. And she saw through the ajar door of the house's master bedroom. She entered it with the same leaden weight in her stomach she always did. The walls were blank, with no sign of the little joys and tchotchkes a normal couple accumulated. Spartan by choice and not necessity, there was a king-size bed; two separate bedside tables (one for each of them) and two wardrobes set on opposite walls. Away from each other.
Who was she kidding? She couldn't be a wife with tits the size of Mount Myoboku. She'd just be a… a slut! It was stupid. This whole evening had been stupid. This was her life now. A marriage only she seemed to care about.
Resentful, Sakura went through the motions of her evening routine. Shower, brush teeth, floss, silk PJs. Sasuke's of course, she'd always preferred men's pajamas over women's for some reason.
She dropped into bed. It was too hot to slip under the covers, and she was too drunk to change the bed. So she curled up on top of it. Unaware of how desperate she was in the hugging of her chest. And wilfully ignorant to the desires fermenting deep in her mind. Desires which the cum in her tummy sensed.
And responded to.
Sakura didn't notice her cum belly shrink. Rather than seed her with babies she wasn't prepared to feed, Naruto's miraculous semen soaked into her womb. And then spread throughout her fit, slender body as miraculous energy. Energy which converged upon our heroine's modest breasts. It read what she wanted most. And then gave it to her.
That night, Sakura dreamed. Weird and sexual shapes. Mounded and pale. Soft warm and crowned by nipples. Smothering from all sides. Shovied in her face. Nipples in her mouth. Tits filled the grip of her hands. Tits cradled her feet and her tired legs. She couldn't breathe.
She tried to fight but the tits absorbed her shoves. The harder she pushed the tighter they squeezed. A coffin of titflesh engulfed her head to toe and hip to hip. Hard nipples tickled the insides of her thighs. Then scraped higher, lubes by breastmilk. Tickled the heated pink folds at the apex of them. Penetrated her… filled her… Thrust in her~
Then her alarm went off, Sakura awoke in a sweat. Bolt upright, tummy aching empty. Disoriented she pulled up her loose shirt, expecting the cum belly from the night before.
"What the hell?" Sakura poked her toned midsection. Flat as it always was.
Confused she threw back the covers. Expecting to see a big, big puddle of jizz soaked into her mattress. But her sheets were desert dry.
"Okay that's weird. That was, like, what? Two quarts of spunk? Where'd it go?"
Well, whatever. She'd solve the mystery of the disappearing jizz later. A glance to her alarm clock confirmed it. Today was Monday. And she had a double shift at the hospital. Sure she spent half the time behind a desk these days but still, double shift. Ugh.
Sakura swayed to the bathroom. A needle of a headache jabbed her nose's bridge. Minor hangover, probably, she'd drink some extra water with breakfast. Blearily she tied back her hair and began to brush her teeth. Until she spied an odd shadow down her collar. A hint of cleavage between her—
"Mmf? 'Ah phuk?" She asked with her mouth full.
Toothbrush bit between her molars, Sakura pulled her shirt off. She'd slept braless last night like always. Brow furrowed, she cupped her breasts. They felt… full. Heck they even looked swollen. Was it the light? Maybe. Curious, she pinched her nipples—
"Gahk!"
Sakura spat out her brush. She'd almost gagged on it. Dimly she saw it skid around her sink. Lubed by spit and toothpaste. A sight which came to her soft around the edges. Steamy and panting from the sudden sensual throb. A experimental squeeze confirmed her chest had changed. She had boobs! Modest ones mind you, just a pair of perky inverted teacups. But still, boobs!

Awash in questions, Sakura sped through the rest of her morning routine. Shower and makeup and clothes and all the rest. Sure maybe doctoring was a utilitarian profession. But dammit if she wanted to look good she was going to!
Breakfast was a little different though. She didn't just drink one extra glass of water, but three big ones. Straight from the tap no less. It wasn't until her coffee kicked in that she realized how odd that was. She must've lost more fluids than she thought. Yet no amount of strangeness could dampen the spring in her step.
She wasn't a flattie anymore! Sure it was a little weird but Hinata would know what was going on with her. Better yet, she could ask Naruto. Not today though. Today was a work day. Probably… Friday. Yeah, Friday!
At the hospital she was a whirlwind of activity. Treating patients, filling paperwork, plus the occasional errand to appease the director. A pudgy and prudish civilian named Ron Stoppenbone (very unfortunate name). Sure enough, her fetishy uniform felt a touch snug about the chest. Funnily enough, it didn't feel anywhere near as embarrassing as usual. Though her fellow lady doctors still grumbled about it.
Not that she blamed them. Pants were NOT part of the dress code. And neither were panties (you had to bring your own from home). What did come standard, though, was a short-sleeved white coat, just barely long enough on the bottom to serve as a short skirt. Emphasis on short, Sakura had had to get an extension on hers. Otherwise the bottom half of her meaty backside would've hung out free for all to see. Bouncing in the breeze…
…A-anyway. The cap and nylon stockings were equally kinky. Small and sleek in turn. More fashion than function. It was kinda nice, actually. Free of such a lead sinker on her mood, she didn't have to worry about bending over in front of her male patients.
Which they definitely did not mind.
That night, she roof-hopped home. Exhausted but satisfied. Some instant ramen served as dinner, after which she dropped off to sleep, on the couch. Reruns of her favorite soaps serenaded her to sleep. She woke up the next morning to a crick in her neck. And larger breasts.
Now they were some substantial handfuls. Training bra no longer happily tight, but uncomfortably so. Flushed and confused, Sakura dug out a measuring tape from the kitchen drawer. She snagged a notebook from Sasuke's home office to record her findings. Sakura inspected herself in front of the bathroom mirror, topless. Tape wrapped around her chest. Careful to pull the flexible cloth tight to her sensitive bosom. Gingerly so she didn't accidentally set her new and improved niples off, again.
"82 centimeters… So, 32 inches." Sakura crunched the numbers in her head. "Holy crap I'm a C-cup? Jesus, I've gained two cup sizes in two days!" She let out the tape a touch "…Make that two and a half. Maybe a little more."
She jotted her new bust size down on a fresh line under her original measurement. After a moment's pause she added the word TENDER. With two lines on it. She almost missed work that day. Arriving a half hour late, she'd had to sneak into her office's window. And then pretend she'd been there all night. Surprisingly, it worked. Nobody questioned her on it.
Wednesday brought another surprise. Her boobs leaped up another two sizes. A full ten centimeters of titty girth gained. She'd skipped over the vaunted benchmark of the DD-cup. And gone straight to E. A level where a woman could be considered truly busty.
She made a quick pit stop before her shift. At the fanciest bra shop she could find. A few months ago, on one of Ino's shopping sprees, she'd found the cutest bra. A lacy pink one, half translucent and with some deliciously low cups. Yet she'd found her heart shattered when she saw the tag; 36E.
But things were different now. She strutted into the store with pride and picked her prize off its rack. It cost twice as much as the brassiers to its left and right. But she didn't care. She bought it with pride and slipped it on in the changing room. It fit snug as a bug. So perfect she even slept in it.
But that night, the tit-smothering dream returned. With a vengeance. More vivid than ever with the sound of soft and throaty giggles. Come the morning her lovely lady lumps bulged from their lacy prison. A concerned measure of the tape confirmed the obvious. She was an F-cup now.
Thursday was the day people treated her differently. Her boobs were obvious now. An unmistakable swell across her uniform's chest. A pull on the double-breasted buttons. A distinct bounce when she ran to a patient's aid. Now her female coworkers were not so warm. Oh they were friendly enough to her face. But their smiles no longer reached their green eyes. When she peeked in on them, she saw that the subject of her brought up folded arms and curled lips. Jealous barbs pertaining to her 'obviously' fake boobs.
Rumors abounded about where and who she'd gotten her 'work' done. Who she was trying to impress. And which of the hunkier male nurses they had definitely seen her fuck in the broom closet. What a slut!
By the end of the day, she had no friends at the hospital. Just rivals and admirers.
Friday came like a blessing… and a curse. The weekend was ahead, but its morning began with her pinned under a fat pair of GG-cups. (98 centimeters around. I.e. 38 inches). Head-sized suckers which cast a shadow over her face. A shield from the sun's rays. Boobs which popped out above and below her precious pink bra. Suckers so voluminous they stretched its cups flat. And dug its strap into her back. After she cut her prized brassiere off, she faced facts. With a heavy heart she put the bra to rest, in shoebox under her dresser.
After work she went bra shopping. Nothing in the fancy boutique fit her now. Not even the hideous green one with more ruffles than Rock Lee's drag dress. Thusly banished from the haunt of 'real' women. She crossed the dividing line between normal and busty. Where her only option was the plus sized boutique. There, she got her first genuine smile from a woman in three days.
"Damn, honey. You look a little—" The dark-skinned and Rubenesque sales lady cleared her throat. "Unsupported there."
Sakura sighed. "You've got no idea. How big do the bras get here?"
"Mm, big tit problems. I can relate." The sales lady ushered her to the back. "Let's see if we can't help."
A few minutes of measuring and prodding (all professional) confirmed her rough estimate for her cup size. Her guide's eye contact was flawless.
"Yup, your math's on point. You've got a GG-cup down there."
"Can you fit me?" Sakura asked.
"Sure, We'll have to break out the akimichi sizes though. Some of those ladies get heavy up top."
A few minutes later, her new friend came back with the biggest they had. It was a touch snug, but it got her tits properly lifted and shaped. A test walk helped Sakura get used to her new center of gravity. During which she spied a sign over the bra rack. WE DO CUSTOM WORK, it said.
"Hey, how big do your custom bras go?" She asked as she paid for her new undergarment.
The sales lady blew out a long breath. "Pretty big. I'd say a P cup at most."
Sakura nodded, pensive. "I'm gonna need one of those."
"There's no way that size'd fit you, honey."
"Not yet." Sakura eyed her chest as if they were about to explode in size right there.
"…Well, they say the customer's always right. I'm not turning down a sale."
Saturday was the biggest milestone. The day where her boobs swelled to a truly drool-inducing size. A match for her mentor's infamous rack. Sakura Haruno was officially an H-cup. 103 centimeters around the tits (40.5 inches in imperial). It was also the day where her akimichi scale titty sling proved truly tight.
It was also the day where she could finally, fucking finally(!), corner Naruto. And boy howdy was she going to pump him for cu—Information! Pump him for information! If Sakura didn't know better, she would swear these new boobs of hers were inflating her libido with all kinds of filthy fantasies…
Sakura sensed the big blonde stud's chakra with ease. After all, his aura was about as subtle as Killer B in a china shop. Huh, weird. Naruto wasn't at home. And he wasn't chilling at puLse either. He was at the… water treatment plant?
Her roof hopping had grown more ponderous. A much more fiddly affair by virtue of her fattened sex melons. Much more perky than Tsunade's. They bounced obscenely with every leap. Almost as if she'd been born and raised on the moon. With its low gravity. She had to hold her girls down with one arm the whole way.
Konoha's water plant lay close to the center. Built with defense in mind, it looked like a fortress from the outside. Sakura, though, managed to slip in undetected. Avoiding gaggles of hard-hatted workers in her path to the elevators. She followed Naruto's chakra signature to the sub-basement. Where the village's water underwent its final cleaning before distribution.
The second she reached the bottom floor, she heard Them. Animal grunts and groans and moans and 'No-s!' and 'Yesses!' echoed off the mazework of overhead pipes. Sakura followed her nose, followed the stench of sex. Afraid of what she would find. But her nipples were so stiff, they seemed to pull her to the source.
Sakura found the man she wanted to see. Naked and next to an open exit valve. An open through line to Konoha's water supply. All but begging to be tainted. She could smell the scent of potent cum wafting from the hatch. Of miraculous semen intermixing with the clean liquid. Which should have been the most shocking part of this discovery. But it wasn't even close. Because he had all twelve inches of his big dick buried between his own mother's enormous tits!
Even though she was on her knees, Kushina had her only son pinned to the wall. Massive pregnant belly jutting between his spread legs. Visible past them, and smushed ever so slightly against the concrete wall he leaned against. Tennis ball testicles pooled on her twitching, kicking mommy tummy. Head back and eyes shut as he savored his mother's filthy paizuri.
Schkluk…
Schkluk…
Schkluk…
Schkluk… Schkluk…
Schkluuuuuuuuhhk…
Sloppy and loud, over-lubed with precum and semen and the occasional squirt of breastmilk. Kushina mashed her milk-laden melons 'round the biggest cock Sakura had ever taken. His beefy scepter still frightened her. Still compelled her to cover her pussy out of fear. Even while her gasps made her breasts bulge toward the object of her lust. Through the half-unbuttoned top of her iconic pink dress.
"Wh-what… What the fuck is this!" She screamed. She'd heard Naruto had developed a taste for Kushina's swollen, gravid body but… oh god<3
Lazy as any king, the man who'd changed her cracked one eye open. " 'Sup, Sakura-chan? How're the new tits treating you?"
Sakura babbled so fast you'd think she was beatboxing. Suddenly self-conscious of her own huge tits, she covered them with one arm and then jabbed an accusing finger at the pair. Alternately at him and then her. Her dismay drew only a smirk from Naruto. Kushina was insensate to her. Because the very tip of her son's distended boner jutted from the top of her cleavage. And she couldn't resist worshipping it. Kissing it… licking it… Lavishing love on its fat purplish tip with her soft little tongue… Absolutely making the fuck out with the head of the cannon.
And this wasn't during those moments where Naruto thrust into her tits. Driving up her gigantic mommy milkers and then dropping them in a chorus of jiggles and plaps and watery tit-ripples. Brief moments where his shaft plugged her mouth. Stretched her plush lips around its forearm-thick shaft. Cut off her air and rolled her eyes back in a teary whine of dominated ecstasy. The Uzumaki clan matriarch wouldn't be answering questions any time soon.
Especially because the only words she could manage were filthsome babblings about her precious son's gigantic dick. Ramblings about how he'd ruined her for other men. How she could feel him inside her belly every time he penetrated her. How she knew that the fact of him having his nuts on her gut meant he could feel their kids kick~ How he could pump her full of TWELVE babies and she would still carry them with pride!
So… yeah. Kushina was kind of out of it. Sakura found her performance especially throat-drying, and nipple stiffening. Yet still she mustered up the courage to accuse him:
"You did this to me, Naruto! Why?"
Naruto's smirk was indelible. As if having his big dick lavished with incestuous love was an everyday activity for him. Because it probably was.
"It's what you wanted, right? Bigger tits?" He jiggled Kushina's juggs for emphasis.
"N-not this big!" Sakura protested, face bright red.
"Yeah… probably a whole lot bigger, right?"
Sakura's jaw dropped. No way, she wasn't done growing? There had to be some limit on these damn boobs, wasn't there? Naruto seemed to sense her question. His eyes appeared red and slitted in the low light.
"My semen gives you the body of your dreams. And you've always been hung up on your chest."
Sakura tried to splutter a denial. But she knew it was fruitless. The sheer impossibility of this whole scenario overwhelmed her. As big as she wanted to be? The body of her dreams? Oh, fuck~ There was no way she could function with knockers this huge!
"You've gotta stop this, Naruto! Please! These stupid impractical tits are changing everything!" She begged.
"Sorry, Sakura-chan…" He trailed off into a long grunt. She saw his balls pull tighten against Kushina's cum-shiny stomach. "It's a one-way deal. There's no takebacks."
"But I've got a life, Naruto-kun. I've got a career and a… I've got Sasuke. I'm losing all of it." Sakura tried to muster the appropriate desperation. But they all sounded like obligations when she named them And all she could see were Kushina's tits wrapped around Naruto's beefy sausage. Greased to shiny perfection. So snug and tight and warm<3 It took everything she had not to picture herself down there. In Kushina's place. Her rightful place, between her master's legs.
"Did you… Want any of that?"
"I… Yes!"
Naruto dug his claws into the concrete. A brace to hold him up despite his weakening knees. His next question came as a bestial, sexual snarl.
"Then why are you still growing?"
"…"
Sakura couldn't answer. And she never got the chance; because that was the exact moment he blew his stack. Semen audibly gurgled within his waterskin scrotum. Sakura stared with shrunken pupils and reddened cheeks at the sight of his shaft swelling. Opened and ready to fire. Kushina swallowed his tip at the moment of eruption. But it was not enough.
He blasted inside her mouth. Gamely, the veteran cocksucker worked her throat like an irrumatio champion. Gluck after loud and lewd gluck filled the air. Yet still the semen back up and bulged her cheeks. Still it shot her eyes wide and backflowed past her lips. To burst in sheafs all over her tits. His cock popped free in an off-white spunk shower. To sputter its last few aftershock cumshots into Kushina's luscious red hair.
Sakura tried to back out of the scene. Still deep in denial. But found the chugging metal chest of a machine appear behind her. Overwhelmed sexually AND existentially, she slid down it and sat in a daze. Hypnotized by the delicious show.
The performers changed positions. Stripping off their shoes and pants to prepare for the main event. But Kushina stopped her son mid scene change. "Wait, one thing first."
Kushina stood up with a sensuous groan. One hand on her belly and the other on her back. Daintily, and with a grace unnatural for a pregnant woman, she glided to Sakura's side. Her low, knee spread squat before the younger woman proved equally defiant of ponderous gravity. From the corner of her eye, Kushina planted a clawed hand next to her head. Sakura felt sharp fingers cup her chin with a mother's gentleness.
"Hi Sakura~" Kushina purred.
"H-hi Ms. Uzumaki—Mmph!"
Kushina kissed her. Fast and hard. Tongue in her mouth. Sakura tasted Naruto's semen and she swore she lifted free of the floor. Beefy and Umami laden semen drowned her tongue, she whined into Kushina's mouth. Which still smelled of his dick.
"Mmmmmmwah<3!"
"Haah… Haah… What was that for?" Sakura caught her breath. Tits all a-heave.
"No reason. You're way too cute."
Kushina left her side with a wink. Jiggling back to her master and then assuming the position. Face down and ass up. Belly filling all the triangular space between her thighs, her body, and the floor. Huge tits smushed to each side like punch balls full of jello. Belly's underside exposed in a low, ponderous hang between her muscular thighs. A show of how her linea nigra connected perfectly to the top of her pussy slit.
"Come on, honey~ Momma needs that beast inside her right now…" She wiggled her fat ass for emphasis.
Sakura did the only thing she could in the moment. She ran. Unable to accept the perversion of seeing Naruto penetrate his own mother. Yet she still beheld it in pieces, reflected in the shadows overhead. A sudden insertion followed by a vixen's scream. Half sexual and half addict's release. Echoing in the wake of her flight she heard Naruto address her one last time:
"You're gonna be okay, Sakura! But you've gotta stop fighting it!"
She wandered home late. In a daze. Still with Kushina's rakishly angles cum kiss on her lips.
This was what she'd wanted, right? …O-of course not! There was a difference between fantasy and reality! How was she supposed to function with boobs this huge? How would she go out when she'd look like a prostitute regardless of what she wore? How could she maintain any friendships with other women with these big tits in the way? And she wasn't even getting into the catcalling…
No, these boobs couldn't get any bigger, right? They just couldn't~ Sakura tried not to bite her lip at the thought. Not to squeeze her thighs together, aroused by her own distress over her swelling melons. And they really were melons now.
Sakura slipped a pillow between her boobs as she drifted off to sleep. With a desperate mantra upon her lips:
"They're not gonna grow anymore… They're not gonna grow anymore… They're not gonna grow anymore…"
