A bead of sweat trickled down Sakura's shapely collarbone and into her rosy cleavage. She adjusted her Hokage cloak, flapping its edges to fan herself with the cool night air, but it did little to cool her down. Only a few more to go, and she'd be done with the last of her prisoners…
"Rather hot tonight isn't it?" she said feverishly to the Suna-nin lying on the operating table before her. "Hot and cold, cold and hot…"
The Suna-nin in question was currently unable to answer, as the stress of the transformation from male to female had taken its toll on him— or rather, her— leaving her temporarily comatose. With a quick squeeze, Sakura flattened the woman's newly grown mounds… and that was the moment smoke started pouring from her cleavage.
"I'm on fire?" Sakura yelped. "I AM on fire!!"
Sakura leapt to her feet and started patting down her plump bust, but it continued belching acrid smoke, sending her into a coughing fit.
"Sakura!" Naruto yelled as he barged into the room.
He immediately identified the source of the smoke and started slapping Sakura's jiggly breasts in order to put out the suspected fire.
SHRIIIP!
The E-cup bra's stitches started popping one after the other.
"Quit doing that, Naruto!" Sakura said shrilly, shoving him aside with one arm. "If you're standing in front of me when the seal gives out, you're as good as dead!"
Sakura's breasts seemed particularly determined to escape their textile confines. Her bra straps began creaking as the semi-elastic material stretched to its limits to give way for the burgeoning masses growing within, trembling and shuddering as flesh oozed out from the sides…
"Ouch, ouch, ouch!" Sakura yelped. "The straps are… biting into my boobs…! So… tight!"
Though her breasts had swollen to the size of watermelons, they were squashed against her chest by Karin's bra, which seemed equally determined to hold out until the bitter end. Blobs of hot flesh began bulging out from beneath the overstretched straps, and soon Sakura's face was buried in her own cleavage as the top of her breasts swelled up and over the cups. The large cups of the E-cup bra now seemed tiny, covering only her nipples…
BANG!
And without warning, the fūinjutsu gave out. The brassiere shot away like a cannonball, never to be seen again, and now that the dam had broken, all hell broke loose. A torrent of undulating breast flesh exploded forth, filling the room in one instant and knocking down the senjutsu-chakra-reinforced wooden walls in the next, and still they continued spilling out uncontrollably into the forest, until they finally stopped…
"Status!" Sakura yelped.

"GYAAAAAAHHH!" Sakura screamed.
Sakura's breasts rose before her like twin mountains, so vast that they rested on the ground and still towered above her, even when weighed down by their own elephantine mass. Left, right, down, up, there was nothing to see from her perspective but the endless expanses of her white skin. She literally was as big as an Asian bull elephant… and a rather large one, too. Though she was a little on the runtish side for an African savannah elephant.
"Sakura-chan, you're huge, ya know!?" Naruto gasped in shock. "Just how many did you—"
"Seven thousand and four!" Sakura said in a panic, feeling her heart hammering in her chest. "Naruto, I can't see anything in front of me! I don't think I can move! Do something! Help!"
Ziiiip!
The sound of Naruto unzipping his jumpsuit rang out.
"Not that kind of help!" Sakura screeched. "Go get Karin!"
The undersides and sides of her breasts were bleeding where they had scraped the walls and floor when they burst out of her top, but most worryingly… she couldn't feel the tips of her breasts, though they ought to have been hurting just as much as the rest. The flesh went from ouchy and warm to stinging and deathly cold, then to no sensation at all.
Badump.
"Argh!" Sakura groaned as a stabbing sensation lanced through her heart. "Naruto, hurry!"
"I'm going, I'm going!" Naruto cried.
Since Sakura's mountainous breasts had demolished half of the wooden prison complex that held those she hadn't yet stripped of their chakra, Naruto simply jumped out through the hole in the wall and began flickering towards the Hidden Leaf.
Badump.
Sakura's delicate hands scrabbled uselessly at her chest, lightning dancing at her fingertips for a few seconds before winking out. Jolting her heart wouldn't fix her arrhythmia, it would only restart it when it stopped; she needed something more permanent. Biting down on her lip to stave off the pain in her chest, she began drawing upon the maelstrom of physical energy contained in her enormous body, moulding it into chakra with her spiritual energy…
"Body Revival Jutsu!"
Sakura's heart swelled in her rib cage as she activated the muscle's cells, forcing it to beat with regularity, but there was still no sensation in the remotest parts of her breasts. She had solved the immediate and life-threatening problem of heart failure, but there was still the matter of her chest measuring over fifteen metres… she was over eighty times more breast than girl.
Even though seals such as the Yin Seal and the Celestial Empress Lotus Seal granted her the ability to maintain ninjutsu like the Transformation Jutsu and the Body Revival Jutsu indefinitely, this was still a stopgap solution. While Sakura could forcefully strengthen her heart now, this would result in unnaturally high blood pressure, and this meant further damaging her heart, blood vessels and the valves of her veins and arteries.
But that wasn't the most pressing issue.
No matter how strong Sakura made her heart, there was no defying the laws of physics. She was a girl, not a whale; her blood vessels were of normal size for a human. A fifteen-metre bustline meant tremendous friction to overcome for her blood to reach as far as her nipples.
As with all things, fluids preferred to take the path of least resistance, which meant that the furthest parts of her body would simply go without their blood supply… and even if blood could make it to her extremities, it would long since have been sapped of useable oxygen along the way.
Sooner rather than later, her breasts would necrotise, starting from the tips.
"Maybe the Breast Diet Jutsu?" Sakura muttered to herself frantically. "No, the Celestial Empress Lotus Seal can't even contain one hundredth of my current chakra capacity, let alone the immense chakra that would be generated by burning all that mass! If I released that much energy into my pathways without an outlet, I'd explode!"
The Body Revival Jutsu was designed to temper the muscles, but there were no muscles to be found in Sakura's breasts. She had to find something else…
"That's right!" Sakura gasped in pain. "Lady Katsuyu is the size of a mountain, and she's completely fine! There has to be a way!"
Sakura quickly summoned Katsuyu to ask her for advice.
"By all rights, you should already be dead, Lady Sakura, and your breasts should have withered away days ago, long before you reached this size," Katsuyu chirped. "But you aren't dead, and you aren't suffering from sepsis, which can only mean one thing…"
Sakura held her breath in suspense.
And held it…
And held it even longer…
And then held it some more…
…hang on.
"You don't need to breathe at all, do you?" Katsuyu said cheerily, waving her eyestalks to and fro. "Yes, it's exactly as I suspected… I'd already noticed it just from standing in your palm, but you're no longer quite human, are you, Lady Sakura? The chemicals in your sweat are not those you would usually find in your species…"
The realisation hit Sakura like a sac of bricks.
Normal rules of biology no longer applied to her, because she had ascended to the level of a Divine Being. She no longer needed to breathe, eat or drink; after all, the Ōtsutsuki spent much of their time roaming through the vacuum of deep space in search of stars to suck dry. The only sustenance she needed was chakra; the substance would support all her bodily functions.
Come to think of it, her human half could still produce chakra by linking her physical and mental energies, while her Ōtsutsuki half could consume it like food. As long as she continued hunting down breasts, she would never need to eat again. All that to say, the only limiting factor to her size was her chakra pathways (and perhaps gravity), which meant she could still grow far larger than the size to which she had already swollen!
"Which means…"
She had found an unlimited energy glitch? Spiritual energy was free, and chakra contained far more energy than the sum of its parts!
"Which means it's all in your head!" Katsuyu concluded, humming happily. "That's good news, isn't it? You're a strong-willed girl, after all~"
Sakura felt a chill as the night breeze brushed against her nipples, somewhere far beyond her sight, and she shivered slightly. Her breasts felt cold because it quite simply was cold outside, and her heart was beating irregularly because she was suffering from anxiety.
In the end, Sakura was perfectly fine, physically speaking; saved by her half-Ōtsutsuki physique. She had been worrying for nothing, or perhaps, she had been hoping for something to worry about, if only to avoid going outside…
…where Madara was.
"Thank you, Lady Katsuyu," Sakura said, bowing as best she could… which mostly involved her nose visiting her cleavage. "I'm grateful for the help."
"It's okay to lose your way, Sakura-chan, all that matters is to keep trying until you do find your way back," Katsuyu said softly. "I know things have been difficult for you ever since Lady Tsunade's passing, but remember that I'm always there for you… don't hesitate to summon me if you run into any more problems, okay?"
Sakura dutifully nodded.
"Given your current strength, you should easily be able to summon me in my true form," Katsuyu sang before vanishing in a puff of white smoke. "Make sure there's enough space around you if you do~"
But in the meantime, Sakura was still a beached whale, utterly unable to shift her enormous bulk by even a single millimetre.
