"D-day fourteen. R cup… 131 centimeters… 51 inches…"
Sakura bit her pencil's tip. Topless and with the tape hung on her neck. After hours of desperate masturbating in the kitchen, she'd finally hauled herself off to the shower. And then to bed. Luckily for her, the girls hadn't grown any more after their sudden growth spurt. Thank fuck for that! It'd been as if the sight of Naruto pummeling his sisters' pregnant bellies had sparked a competitive edge in her breasts. Compelled them to try and grow as big as Nori and Naruko's swollen, slutty sex guts.
Tits resting on the kitchen table. She bounced her left foot as she wrote. Describing the lewd dreams she'd had the night before. Psychedelic ramblings of lewdness centered around the gyrating shapes of beautiful women. The aquiline swoops of bulky male muscle and, most maddening of all, the body jarring thrusts of massive club-like cocks. Idly she doodled one of them in the margins. In loving, veiny details. These were even bigger than the ones she'd dreamed up last week. But not as meaty as the pipe Naruto himself lugged around in his pants.
Suddenly the doorbell rang. Sakura all but leapt from her chair. Careful to grab the table to the forward slosh of her tits didn't pull her over. Fast as her pornographic milk tanks would allow, she dashed for the front door and threw it open. Forgetting she was naked.
Luckily for her the deliveryman had already left. Although she damn near gave a middle-aged man a heart attack. Who had for the record, been very much minding his own business. Sakura squeed in joy when she saw the discreetly brown box. Dashing inside she full on ripped it open. Finding the bra inside.
It was a heavy-duty, utilitarian thing. Hooked in the front for ease of putting on. The padding in the cups were thick, all the better to hide her huge nipples. And the straps appeared to be woven from some sort of seatbelt material. Strong enough to survive a high-speed crash, or some especially violent boob jiggles.
Sakura clipped the garment on. With more effort than she would have liked, but this was the most supported she'd felt in weeks. Overjoyed, she ended up doing jumping jacks right there in the kitchen. Commando of course, marveling at how the Kevlar-reinforced bra cups kept her girls from bashing her face. She didn't have to wear the bikini anymore!
Tragically, this extra substantial grade mammary harness fit her for all of a day.
==0==
Sakura woke up with breasts the size of jack-o-lanterns. Floorboards hard against the back of her head. Left arm smushed awkwardly between her tall mattress and the gelatinous mass of her left tit. She'd rolled off her bed in the middle of the night… again. And her tits were so big now, they almost filled the hip-width walkable space between the frame and her bedroom wall.
Heavy… oh god they'd gotten so heavy~ Sakura gasped beneath their wobbly weight and struggled to catch her breath. Thanks to the chakra-stockpiling seal on her forehead; it took a minute for her chakra to warm up each morning. And so she started every day with their mass crushed heavily on her chest. Pinned and helpless as the stark reality of owning such epic bosoms bore down on her.
Bit by bit she felt the telltale warmth of her forehead seal, and the strength she'd grown to rely on surge through her arms and chest. Electric and intoxicating, almost as nice as the cool morning breeze on her bare nipples— No, stop it! Bad Sakura! Bad!
Suddenly she could breathe properly. Superhuman chest muscles lifted and dropped her mutated milk melons with casual ease. The weight was gone but it had an unfortunate side effect. Sakura felt her breasts wobble slightly on her chest. Practically weightless now thanks to her strength-enhancing technique, it didn't take much to make them jiggle. At least she could lift them now.
But she still found herself stuck. No matter how she twisted and shoved in the tight confines, Sakura couldn't get herself on her feet. It wasn't an issue of strength, but leverage. Between her smooth bedroom wall and the loose blankets on her bed, she didn't have any good handholds. Not to mention, it was starting to feel cramped in here. What with the corner of her bedroom boxing her in from the top and left side, her bed blocking the right, and those stupid, cursed bosoms jiggling and wiggling below her chin. She couldn't see anything past them, hell, she hadn't seen her feet in days.
Okay, time for plan B.
Sakura braced one hand on each side of her prison and pushed. Loud grinding signaled the moving of the heavy oak frame. Shoved a good foot away, enough to give her some elbow room. One hand on her lower back and the other cradling her fluid-filled bosoms, she rose like a beleaguered pregnant woman. Bleary-eyed and grumpy from the lack of coffee in her system.
"I'm not a pervert. I'm not a pervert. I'm not a pervert."
The mantra eased her bad mood a little. Enough to motivate her through her morning routine. She'd moved her bedside table and its accompanying lamp to the foot of her bed, not very convenient but plan B had knocked the damn thing over once already. Rummaging through its single drawer, Sakura withdrew the dreaded tape measure. Grave and blushing she measured her tits, with all the dread reverence a supermodel treats the bathroom scale.
"138 centimeters, that's what? 54 inches?" Biting her plush lower lip, she let her sharp mind obsessively crunch the bra calculation. "Oh my god, I'm an S cup~"
Her bust size would never not shock her. How the hell was she supposed to go out with tits this big? She was a walking sexual harassment lawsuit. One slip and every man woman and child in the hospital would know the color of her nipples. Maybe they already did. She told herself she hated the idea. Tape forgotten, she squeezed the front horizons of her gargantuan girls. The puffy areolae behind each nipples. Sure enough, like clockwork…
"Ah<3" Sakura's smoky gasp would have made a priest blush.
Ivory cream pearled whitened her dark pink nipples. Not more than a few days ago they'd been the same color as her hair. But the sudden flow of milk had darkened them to a lewd shade. Thickening them to the girth of a lumberjack's thumb. Worse, they almost as long as they were wide. No amount of clothing could hide them now, her nipples stuck through everything.
She blamed Naruto for this, and those slutty sisters of his. Something about catching them in the act, of seeing his gigantified dong shine all slippery with the ultrasound gel. Or maybe it'd been all the poking and prodding and squeezing she'd had to do on the twins' huge pregnant bellies. Either way, something perverse had awakened in her. A new fetish fed to her brain, primed to pickle it with dopamine-soaked daydreams, courtesy her inflating funbags.
"I guess… The pump…" She caught her breath. "Slipped off, again."
Ruefully, she eyed the infernal device. Like a small vacuum it lay on her bed. Plugged in via an extension cord. Its long neck of a hose spattered with breastmilk. Bifurcated at the end to feed a pair of heavy-duty nipple cups. For the most part, it looked like a c-pap machine. Compact and (almost) tasteful. Out of pride, Sakura had refused to purchase the person-sized tit suckers farmers used on their cattle. She wasn't a cow dammit!
But oh could she express like one. Even from where she stood, she could see the crack in the pump's plastic reservoir. She'd overwhelmed its design and now she'd have to buy a replacement. Stupid boobs. With a grumble she gathered the device up and carried it to the attached bathroom. Carefully she popped the broken tank from its slot and laid it on the back of the toilet. She'd spilled her breastmilk once before and that'd been enough.
Positioning the pump's body in the bottom of the bathtub, Sakura took a deep breath and flipped the device on. Hsst hsst hsst hsst… The rhythmic soft sucking of the nipple cups quickened her breath. She knew what was coming next and it scared her how much she enjoyed it. Like a succubus' kiss.
Shuk shuk shuk SHUK…
Shotglasses of clear plastic shuhked tight to her nipples. Rosebuds sucked swollen and pert, the milk began to flow. A heated gasp left her lips and her hands flew to her torpedoes' undersides. She felt the milk bubble inside her. Pressure build behind her nipples, hot a tingly like a man's orgasm.
Then the heat built elsewhere. Between her legs. No amount of squeezing could make it go down. Fluid and hot in her pink flower. Warm as the fizzy sparks in her chest. She felt three orgasms build all at once. One in her pussy and one in each of her cursed tits. Desperate she grabbed a wadded up handful of toilet paper and held it to her groin. She knew what was coming next.
Fssshh~
"Aahh… Ahh… Ah.. Anh<3"
Sakura felt her pussy pop, her milk came. Richly and warm in spurts, cognizant of how her breasts twitched with every cream shot. Through lidded eyes she saw the milk, her milk, sputter from the pump's open mouth like a half-kinked hose. With shaky hands she unplugged the drain and switched on the water. Praying she wouldn't clog the tub today.
She'd hung her tits over the tub's edge, in case the sucking cups burst off her nipples. Which meant the shower's steamy spray rained all over them. Dozens of hot watery fingers tickled their taut upper slopes. Lips parted she masturbated, hard and desperate like a wild woman. With no care given for who saw or who cared. Completely uncivilized, a slave to her overly sexual body.
The whole process took five minutes at most. But to her it felt like so much longer, like torturous hours of passionate sex.
Gah! Stop that! Stupid dirty mind!
Once she was done, Sakura sloshed downstairs in nothing but loose silk shorts and an oversized t-shirt. …Well, it'd been oversized at one point. Now it stretched tight around her tits like a catsuit. Its lower hem dangled from their cliff-like projection. Nowhere close to covering her flat and toned tummy.
Ruefully she ate her breakfast, feeding herself a full plate of bacon and eggs with one hand while she browsed one of her medical texts with the other (A bit of 'light reading' for someone in her profession). Ever since the milk had come, her appetite had shot through the roof. Lactating to the degree she did demanded a lot of calories, and fluids. She'd supplemented her morning coffee with a glass of orange juice to keep up.
But when she moved on to the cereal, her heart sank. And not only because her boobs had to lay on the table now, and her book and breakfast had to be pushed to the sides to accommodate them. No, it was because she was out of milk. She shook the plastic jug one last time to confirm it. Dammit, now she'd have to go shopping on a Saturday…
Unless…
No. No way! She wasn't seriously considering it, was she? Thirsty still, and craving cereal, she felt her eyes track up the stairs. She knew exactly where to get milk on short notice. Secretively she crept back upstairs, as if someone were watching her. She snuck past pictures bolted to the walls. Pictures of her and Sasuke, with cracked panes. The first victims of her inflating bust. She'd broken every brittle object in the house by this point. The vases were plastic, the picture frames were plastic. Even the plates and the glasses. She'd knocked them all over with careless wrecking ball swings of her mammoth mammaries— Her normal size breasts! She did not have big tits dammit! These were just normal girl problems.
Silent she stole into the upstairs bathroom. The pump's bottle was exactly where she'd left it. Blushed red and panting, she wettened her dry cereal with the ambrosia inside. She'd never tasted her own milk before…
Delicious<3
Vanilla but with a hint of floral aromatics. By the time she'd bounced back down the stairs she'd eaten half the bowl. Bottle nestled in her cleavage. Before she could think she'd refilled the empty quart with her own milk. It was absurd, a ridiculously perverse act. What if she had friends over? What would happen if they drank her milk? Would they be disgusted? Or would they love it? Would they grow addicted to her motherly nectar? The thought made her wet all over again.

Then suddenly she came crashing back to earth. Remembering who she was and what she stood for. Fuck! She'd slipped again! No way she'd ever do something so perverted like breastfeeding her friends~ Nope nope and nope again, she was throwing this jug right where it belonged. In the trash.
But while Sakura steeled herself for the ordeal of navigating her big tits through a crowded supermarket, she didn't pay attention to where she put her milk. Right back in the fridge.
Of course, a food run wasn't the only errand she had today. There was another, more private matter to attend to. Controlling the flow of her milk. She'd tried pads, plastic cups in her bikini, all the conventional tricks lactating women knew. None of them stemmed her flow. So she resorted to drastic measures.
The piercing parlor lay in a bad area of town, not too far from puLse. Part of an abandoned factory complex, partitioned with drywall into a tiny store. Sakura tried to cover her face when she let herself in. Not that it helped much, considering the yoga ball bouncy appendages jutting from her torso. She was even more conspicuous when she more-or-less plopped her big tits on the classy parlor's glass counter and asked straight out how much they charged for nipple piercings.
Luckily for their reputation, she was the only customer. But the nervous and very nerdy intern behind the counter almost busted an artery at the sight of her tits pillowing out all soft and flowy. Sakura rolled her eyes when he struggled to hide his erect penis. A show of manners which almost caused him to fall off his stool.
"Oh come on. They're just boobs." The act of her folding her arms smushed those throat-drying fucksacks bulging up and so very close to her chin.
The cashier went on break right there. Summoning his female coworker to fill in while he took a 'bathroom break'.
Said coworker was NOT friendly to her. Ninety pounds soaking wet, skinny as sin, and vanishing in a bulky coat. At first she wondered how she hadn't become a curvy sexpot like so many other women… until she saw the half-empty pop bottle clutched in her left hand. Apparently, soda was all she drank. Soda which was (by pure chance) bottled exclusively outside the village.
With a barely restrained huff, the girl led Sakura to the nearest chair. She could hear her mumble mean things about 'bimbos' and 'lower back pain' and 'all silicone diets'. On any other day, Sakura would have been mortified. But the sheer jealousy the skinny little sprite exuded struck her as so damn funny.
Okay, maybe she was a touch insulted. Silicone her lily-white ass. These tits were 100% natural dangit!
The skinny girl guided her giggly, jiggly patient into the chair. It was a padded recliner, like what you'd find in a dentist office. And when she kicked the pedal to recline it. Sakura shot down flat on her back with a gasp. Gravity dragging her milk balloons down with her. To sloppily smack and slosh all over her chest. Horizontal now they spread out like raindrops on a windowsill. But still stretched up slightly conical by the erective force of her big nipples. Sheer volume compelling them to spread out over her biceps…
"So, which do you want?"
The question came through hazy. Sakura barely registered it at first. Mesmerized by her bobblicious bosom. And when it finally penetrated she was still slow to answer. Working one arm out from under her breast to flip through the catalog to her right. She wanted something sensible, not showy at all. But the skinny girl called her gambit for modesty silly. She was getting her nipples pierced for cripes sake. There was nothing modest about this.
Platoons of piercing pictures tromped through Sakura's field of vision. Faceless, none of them really spoke to her. Until one picture leapt out. Bright and perfect~ A pair of bar studs whose ends were sculpted into blooming flowers. But their color made her heart race. Bright pink, just like her hair. Not cheaply chromed but carved from rose quartz.
"…Those." Sakura circled them with one finger.
"Hmm, figures."
The skinny girl loaded her piercing gun. And Sakura felt the overwhelming urge to punish the little brat for her insolence. To stuff a damp nipple in her mouth and drown her with milk. To force her to drink drink drink… until she had a little meat on those bones.
She thought the pain of the needle penetrating her nipples would kill the pink bubbles fizzing in her pussy. All it did was add a red and spicy edge to the horny seethe.
"Ow<3" Sakura licked her lips.
"Of course you like it." Her piercer mumbled.
Grudgingly she helped Sakura wobble her volcanic girl parts back behind the tight straps of her sling bikini. Sakura insisted she could stand up herself. Which she managed, after a few failed attempt to find her balance. Ruefully the cashier led her back to the counter. Sakura paid in cash (Sasuke could NOT know about this). And the girl began to count her change.
"So, do you have a boyfriend?" Sakura tried to make conversation.
"No." The answer came flat.
"Really? I don't know why you'd have trouble—"
She slammed her hand on the counter. "Well we can't all be stupid bimbos with yoga ball tits! Some of us have actual fucking personalities!"
Sakura was taken aback, then she put her hands on her hips. "Wow, rude."
The girl realized what she'd just said. "Oh god I'm so sorry. I dunno what's wrong with me. I've been in the shittiest mood lately."
Sakura pursed her full lips in thought. "Hmm, how much water have you been drinking?"
The girl's face fell. "Nothing. I've been drinking nothing but soda for the past month."
Just as she suspected. It also explained why she hadn't felt the… benefits of Naruto's cum yet.
"See? Dehydration'll ruin your mood fast. Now you know what to do, doctor's orders." Sakura tapped her left breast. "Straight from the tap~"
The young lady flushed. "H-here's your change."
"Thanks, cutie<3"
Sakura left her to steam in her own blush. And it wasn't until the fresh summer air revived her senses, when she wondered what the hell had come over her in there. She fought down the urge to run in and apologize for her lewd behavior. She'd embarrassed herself enough already.
The next five days passed in a blur of work. Dedicated as ever, Sakura recorded her bust's progress through the alphabet's final letters.
T cup… 141 centimeters… 55 inches…
Monday heralded the return of the Paizuri Urge, as she'd started calling it. The fact she had to wear her tight and short uniform unbuttoned to the crotch now made things ten times worse. And the bikini didn't help at all. Because she was showing off the maximum amount of tit a woman could without getting arrested. Well, not technically the maximum. She'd started clipping her nametag over the stretchy little diamond hiding her right nipple. It wasn't much but helped a little.
U cup… 144 centimeters… 57 inches…
Tuesday was when she noticed a change in her patients. Women avoided her like the plague now. Insisting an inferior doctor treat them. For fear of her exponential bustline proving contagious. Which was a bit silly seeing how every woman was at least a little bustier now but, eh, whatever.
Honestly she didn't mind the jealousy anymore. It was the temptation of her male patients she couldn't stand now. These new tits of hers had made her so aware of them. So sensitive to the potential hardness, the unfired male deliciousness hiding in their pants.
One patient had been especially bad. A man not much older than her, who'd only just lost his virginity. And she'd had to give him his first prostate exam. He'd been a twitching ball of live nerves. Right up until he realized he could see her boobs reflected in the mirror hanging over her exam table. Which made him relax so much you'd think he was going to melt. And when Sakura's lubed, latex-clad finger pushed his prostate— Poom. He shot all over the clean paper like a champagne bottle.
Mortified, he'd fled the scene so fast he barely had time to buckle his belt. And it was all Sakura could do to not lick his cum off her table right there…
V cup… 151 centimeters… 59 inches…
Wednesday was especially brutal. She'd forgotten to put the pump on her nipples and her tits had punished her for it. Swelling up double the centimeters they had the evening before. More male patients started showing up for silly reasons. Claiming they had 'headaches' or 'anxiety'. It was so obvious what they were there for. They wanted to see her tits exploding out of her doctor uniform. They wanted to see the inevitable nipple slip which came when she bent over to take their temperatures.
They wanted to shove their dicks up in there and jug-fuck her until they blew their backs out. And god help her she wanted to do the same to them. To boobie bash the crotches of all these perverts until they stopped thinking such dirty thoughts. She was a doctor dammit! Not a prostitute!
X cup… 154 centimeters… 60 inches…
Thursday was another hospital function. Some convention or another she couldn't be assed to care about. She stood there and looked pretty while the senior staff babbled at the stage's microphone. While they read off their notecards. She herself stood in the crowd… sort of. More like the crowd stood around her. Whether it was the men who didn't want to annoy their wives. Or the female-repelling field her bust emanated. There was a big ring of empty space around her.
And like before, she stuck out like a sore thumb. She'd tried to get a new outfit for the occasion. A simple black cocktail dress with matching black stilettos and mesh stockings. Unfortunately, she'd overlooked two important facts;
One, she couldn't wear a bra under the damn thing. So her girls' jiggling was on a hair trigger. They shimmied some even if she sneezed!
Two, big boobs and dresses did NOT mix. Not only did her bulging glands constantly tug the dress's straps off her shoulders. She'd had to heavily modify the garment. Transforming it from a normal dress to one of those side-laced numbers. Picking apart the seams along each side and then lacing them up with shoelaces to attach them again. A change which added several inches of width (and bare skin) to each side. If she hadn't done that, her tits would have ripped the garment clean in half!
Very classy all in all. Oh and her girls skipped over a whole cup size. Can't forget that.
Y cup… 157 centimeters… 61 inches…
Friday itself went about as well as it could be. What with a double shift in the sexual dysfunction ward while saddled with a truly preposterous pair of pontoons. At least the appointments were short. Half the men suffering from erectile dysfunction took one look at her and popped the hardest boners of their lives. The other half only needed to watch her do some jumping jacks.
No, it was what happened that night which really got to her. Sakura had thought her the weirdness of her dreams had peaked but this one? Oh god~
Sakura strained her manacles' grasp. Chained up spread-eagle and helpless, the granite altar seared cold on her back. She could hardly see where her captors had taken her. Or the true nature of this ritual chamber. To the left and right she saw her own pale arms. Above her and upside down she saw a ring of red-cloaked figures. Cloaks tented at the groins to a frightful, womb-clenching size. A protective instinct to squeeze her legs together. To protect her poor vagina from their distended rods.
Not that she could actually see her vagina. Or anything below the shoulders. Because her breasts were as monstrous as ever. A mountain range of feminine flesh spread out wide before her vision. Peaked by nipples as thick as a man's thumb. Stiff in the frigid air. As she thrashed from side to side they swung with her, bouncing comically. Even now, when they were pooled in circles on her chest, their lower curves reached her bellybutton.
"Let me out! You bastards! Let me out!" She screamed to her captors. Hating how much she loved being restrained. At being tamed at long last.
But the figures continued their bizarre chants. Pulling open slits in their robes to haul forth their distended flesh clubs. Deformed logs of uterus churning meat pocked by stretch marks. As if they had all submitted themselves to a sudden, painful expansion of the genitals. Bicep-thick at their girthiest and holding up fist-sized and widely flared cockheads. All the way to their chests.
With two hands they gripped and stroked their vicious members. Their chanting crescendoed and they all fired into the grooves in the stone floor. Grooves which formed a pentagram around Sakura's altar. The cultists filled every channel to overflowing, while they chanted the name of their perverted god.
"Ia! Ia! Sathaguah the Drinker! Ia! Ia! Sathaguah the Drinker!"
The pentagram glowed, Sakura felt the ground rumble. Rumble enough to quiver her gelatinous tits ever so tantalizingly. Seductive even while she herself was afraid. Then something slithered grom the ground below. Pushed through the hard granite as it were soft putty. First one tentacle. And then another and another. Fleshy whipping appendages anchored to Sakura's altar and dragged a pulsating mass of greyish flesh from the ground.
With great effort, the elder god hauled itself up to hover over her. Held aloft by its many limbs. Several crimson eyes opened and scanned her hypersexual body. At first she couldn't read its face. Until a hole like a mouth opened. Showing a mouth full of misshapen teeth surrounded by blubbery lips. And a lumpy tongue slithered around and around to lick its chops.
"Titsssss…" The monster hissed.
"No… No…" Sakura begged. Even as her back arched and offered her fat nipples to the beast.
"Titssssss…!"
Sathaguah whipped two tentacles around her ridiculous appendages. Their clubbed ends split into fleshy petals. Petals which were lined with warty bumps. All arranged around a toothless, sucking mouth. Which was in turn home to a long and rubbery proboscis tongue. Sakura grit her teeth when the tentacles pulled tight. Hard enough to bring tears to her eyes, and slosh the gallons of nutritious milk she carried in each breast.
Those slime-dripping tongues licked her nipples until they shined. Slathered her fattened bust with hot greenish slime. Lubing up her squirming bra-busters for an impending suck-job. That was the first real pleasure Sakura felt. Rising bubbly heat inside each breast. Like balloons full of carbonated soda. Bursting to scatter spicy pink sparks every which way.
"Gah~<3" Sakura kicked at the beast. "S-stop that you stupid tits! Stop enjoying this!"
But it was too late. With a gurgling laugh, the elder god latched his tendrils onto her nipples. Until now, the monster's touch had been clammy cold. But the insides of those sucker-mouths were feverishly hot. Hot and textured like a baby's mouth. Then it began to suck. Sakura cried out, biting her lip to hold back the pleasure with pain. To tense herself so her milk would not express.
Tensely, she fought the elder god's sucking mouths. But those tongues were relentless. And the massaging squeezed of those bumpy fingers worked pint after pint of creamy fluid free of her ducts. Rippling contractions to work all her precious nectar into a high pressure lake behind her nipples. The pressure behind her nipples rose… and rose… The bubbles burst faster. Their sparks overflowed her breasts and spilled into the rest of her body.
Finally, with an audible fssshhhh, she lost their tug-of-war. Squirted into the demon's mouths. Sathaguah's laughter rose as it drank her breastmilk. An act which seemed to free the carbonated pleasure in her tits to flow free into the rest of her body. Flood her molten-squirming and gasping for air between the pauses in her nonstop orgasmic cry. Not many short ones but a single long mating call. The sound of a broodmare in rut.
Sathaguah pried her breasts apart. Guiding her to look down between her cavernous breasts. Finally able to see the rest of her body. She saw a large lump on the elder god's underside. One with swelled with every sip of stolen milk. Until it split open and disgorged an enormous pulsating penis onto her toned stomach. Floppy and not yet erect, its tip reached all the way to her ribs! A pair of basketball-sized testicles followed.
"Oh god… Oh fuck… You're even bigger than you're cultists<3" Sakura whined.
Sathaguah hissed in joy and continued to drink. With each eyelid-fluttering suck on her nipples, his cock swelled up harder. Bit by bit, bulging around the neck. Not longer but thicker. As if were kept erect by milk and not by blood. Pale and sallow flesh turned ruddy and healthy. Braces of tendons strained to hold the monster straight. Twitching as it bulged with twisting pipeworks of varicose veins. Veins which pumped like a heartbeat to feed the beast.
Sakura shook her head fast. "No no no! Fuck no! That thing'll never fit in me! It's wider than my waist!"
But still her body betrayed her. Parting her legs as far as her leg shackles allowed. To aid in penetration. Sathaguah pulled back its enormous dick, and then pressed its missile-like tip against her drippy slit. Rhythmic grunts followed as the beast controlled its own ejaculation. Squirting soda canfuls of precum into Sakura's tiny slit. Until it overflowed and dribbled sticky sex fluid, like a cumshot from the invisible man.
Then the monster fucked in. Sakura screamed, eyes rolled back, so high she didn't make a sound. Whole body pushed by the first gargantuan thrust. Which only worked a bare inch into her snatch. But more thrusts followed, each burrowing the monster's flesh pillar deeper inside her clenching depths. Until her tummy bulged around its ridiculous girth and her waist visibly widened to accommodate the mammoth intruder.
Now the heat in her pussy short circuited sparks all its own. Conductive with sexual red lightning it struck inside her hips. Lighting every nerve on brain-melting fire. Pleasure from her cunt overflowed and mixed with the ecstasy of her tits. Complete and utter sensory overload. Sakura creamed all over Sathaguah's mutant dick. Mouth agape and eyes screwed shut and head dangling over the altar's top. The elder god jarred her entire body with every thrust. Even her massive tits! Which were notoriously heavy. Typically they stayed still while the rest of her moved.
"Good! Good pet!" Sathaguah cackled. "But not big enough. Need to be bigger. Need to make more milk."
Sakura cracked an eye open. "What? What're you—AGH~<3 Are you crazy? I've already got tits the size of blimps!"
"Like I said. Not big enough."
The tentacles wrapping up her breasts retreated. Letting them fall free on her torso again. But their sucking mouth tips still nursed her ridiculous melons. Then two more of the primary arms slithered up from below. But instead of splitting into mouths, their tips sprouted long metal needles. Syringes by any other name. Needles dripping with bright green fluid.
Sakura yelped when he stabbed her with them. One in the side of each breast. She bucked and whined but another thrust of his massive cock cowed her. Helpless, she gasped as the needles retracted. Leaving behind a tiny green spot, which dribbled its excess venom onto the altar. Several seconds passed, Sakura waited with baited breath and then—
"AAHH~<3"
A loud heartbeat hammered thumped once in her chest. Raw volcanic pleasure erupted within her breasts. She cried out and kicked at the beast. Frightened (and growing wetter by the second), as she felt her breasts bubble.
Gurgle…
Skin stretching…
Nipples thickening…
"No! Stop! Nooooooo!"
Sakura felt their weight increase before she saw them grow. Heavier and heavier on her chest. Flowing outwards to the sides. And down lower on her waist. Covering more and more of her torso with every passing second. Until they blotted out her hips.
"Yesssss! Yes! Yes! Yes! Grow! Grow!" The elder god cackled.
It continued to pound her pussy while she grew. Continued to vacuum suck her nipples even as they gained size. As if the act of milking her was actually making her grow instead of shrink. Making her grow faster by the second. Pulse larger in clusters of toe-curling orgasms. Half mad in love now, Sakura squealed as her tits swelled past her hips and down her legs. They hung of her altar's sides now. Smushed along its rounded edges and rapidly approaching the floor.
Sakura could feel everything through her breasts. The sticky hot breath of her inhuman master. Cool drafts and the heat of the chamber's black candles. Her orgasms came in waves. Three at a time, one from each breast and one from her cunt. Colliding in her bulged-out tummy and then flooding the rest of her body. White-crested waves of madness poisoned ecstasy which crashed over her faster and faster with every passing second. Refraction period shortening. Pussy oozing. Nipples squirting. Mouth wide open and eyes rolled back white. Babbling broken half words, short of her desire to wail 'MONSTER COCK!' or 'BIGGER! BIGGER! BIGGER!' over and over again.
By now her breasts had wholly overflowed the altar. Pooled oceans of bouncy flesh, their outer event horizons swelled toward the edges of the pentagram.
Sathaguah's cock pounded her in slow and lazy thrusts. Un-pained by the audible and sloshy slap slap slaps of its gigantic nuts on the altar. Straining now it pushed its monster deeper inside… deeper deeper…! Until he hit her cervix. Stymied for a brief second, the elder god tested this new barrier. And still with an inch of cock outside his new concubine. Unacceptable!
