Chapter 0 - The Secret Scroll

Naruto kicked over a pile of scrolls as he groaned in annoyance. This had proven to be the most boring mission he had been on in years. Sure, he had been out training with Jiraiya for the past few years instead of taking the ranking exams so he was still considered a novice ninja, but everyone knew he had improved greatly under the old pervert’s intense regimen. There was no reason for him to be puttering around on some D ranked mission. The forbidden jutsus that these rogue ninja supposedly were practicing weren’t even any good. Not one of the weird scrolls Naruto had discovered had any relevant combat usage. Most of the jutsus detailed in the scrolls seemed to be erotic in nature. He had found one that increased sensitivity and another that increased the volume of cum one could produce sevenfold. He had casually pocketed those two scrolls during his investigation. If nothing else they would make nice bartering tools for when he tried to convince Jiraiya to teach him new and better techniques. 
    
Naruto was just about to give up when his eyes caught something glinting down between the floorboards of the old run down shanty that these renegade ninja had been living in. Naruto kneeled down and pulled back on the floorboards. The wood splintered and cracked. Eventually, the plank that Naruto had been pulling on ripped free of the flooring. The blond ninja tumbled backwards now that he no longer had the fastened plank to act as a counterbalance. He peered into the now exposed cubby hole. His eyes lit up from what he saw. Hidden away in the corner was a long, slender tube. Naruto had seen plenty enough like these before to know exactly what it was. It was a scroll case and a nice one too, from the looks of it. It was covered in a deep, dark brown lacquer that made it seem almost black. It was perfect for keeping a scroll preserved for centuries if need be. If a scroll had been tucked away in one of these then it must be important. Naruto quickly reached in and tried to discretely add it to his stash of junker scrolls. 
    
“Oh. Hello Naruto. You are planning to share your finding with the Hokage, correct?” came a voice from behind him. Naruto spun around, but he already knew who was speaking to him. Sure enough, Naruto was greeted by the grinning face of his teammate, Sai. Sai’s poor attempt at a smile always made Naruto’s skin crawl. The serenely closed eyes and the flat grin always seemed to lack any actual emotion behind it. It was less like looking at a person and more like looking at mannequin. Sai’s robotic attempts at a personality just seemed to reaffirm just how hollow the pale ninja really was. 
    
“You bet! Old Granny is gonna love this!” Naruto replied enthusiastically as he unfurled one of the other scrolls in his junk pile. Sai’s placid expression never changed as he scanned the contents of the scroll. His eye’s quickly darted over the seals required to summon a pair of spectral hands to jack you off while you did other things. 
    
“Perhaps it is best if we keep those off the official record.” Sai responded flatly; his expression remaining as unchanging as always. 
    
“Oh course, buddy!” Naruto replied far more enthusiastically than he knew he should have. Fortunately Sai was very bad at picking up on the subtleties of human interaction, even when they were not at all subtle as was the case this time. He nodded pleasantly and returned to his search, completely oblivious to Naruto’s obviously forced cheer. 
    
Once the mission was over and they had all given their reports of their findings, Naruto slipped off to the woods to do some secret training. He had not been able to look at the secret scroll the entire time due to too many prying eyes. He slid the scroll out of its case and perused the contents. It certainly looked like a high end jutsu, but there was nothing on it that really gave any indication of what it did. Aside from the incantations and hand seals, the only other information on the scroll was a vague picture of a person with something emanating outwards from the abdomen. Naruto shrugged it off. It looked like the only way to get to the bottom of this mystery was good old fashioned trial and error, and Naruto was nothing if not determined. 
    
He studied the scroll carefully for hours, making sure he had each and every last maneuver memorized before attempting it. When he was sure he was ready, he took a deep breath and went through the motions of casting the jutsu. He completed the incredibly long string of seals flawlessly and slammed his hands down on the image of the person on the scroll. The writing on the scroll glowed brightly and energy seemed to flow from the scroll into his body. 
    
Naruto suddenly felt very weak. All the chakra in his body was draining from him and pooling in his gut. He hadn’t even felt this drained after an intense training session with Jiraiya. He could feel every last ounce of chakra leave him as he fell to his hands and knees in exhaustion. A fiery heat flowed through his body as the demon fox chakra flooded into him to replace his now empty reserves, but soon even the glowing red energy of the nine-tailed fox was being sucked into the black hole that his stomach had seemingly become. It was all Naruto could do to just keep breathing as every last ounce of even the seemingly infinite demon chakra was extracted from him. 
    
It took almost an hour for Naruto to recover enough to be able to get to his feet. Every muscle in his body was sore as if he had been doing heavy lifting for three days straight. As he staggered back to town he slowly started to regain his strength and feel more like himself, but he just couldn’t shake the feeling that something was different. As he got closer to town the feeling became more and more pronounced. 
    
The first thing he noticed was that his clothes seemed to be clinging to him tighter than they normally did in certain key places. The most obvious was his stomach, but his orange and black jacket also felt extra tight around the chest as well. His pants also seemed to be straining a little bit against his butt and bulge. He reached a hand down the front of his pants to try and adjust his dick. He was pleasantly surprised to find that his cock felt quite a bit thicker than he remembered. That would explain why his pants were snug, but it did nothing to account for the tightness in his shirt. 
    
Naruto entered the main gates and continued his labored stroll back to his small apartment. His shirt felt almost painfully tight at this point. He could now tell that his stomach had grown by a fair degree. At first he was afraid that he had stumbled across some discarded scroll from the Akamichi clan. It would explain the increased size in certain parts of his body, but Naruto really didn’t want to be quite as big boned as his friend Chouji or anyone in Chouji’s family for that matter. Naruto reached a hand under his jacket and rubbed his gut experimentally. He was surprised to find that his belly was not flabby at all, but rather firm and taut. It was like he had a basketball tucked away right below his toned abs. He wasn’t sure what was happening, but he figured it would be best if he hurried back to his place so he could study his changes in private. 
    
“Ah! Naruto-kun!” Came a soft voice from off to his side. Naruto turned to see one of his childhood friends waving him down. Hinata was Naruto’s age, and was the sweetest, shyest person Naruto had ever met, despite being one of the hottest girls and one of the most badass fighters in town. Hinata’s long black hair flowed over her shoulders and contrasted nicely with her pale white skin. Her large, white eyes showed excitement to be seeing the blond ninja. “I wasn’t sure I’d get the chance to see you today.” She said timidly as her cheeks flushed red. 
    
“Hinata-chan. I haven’t seen you around in a while. How have you been?” Naruto asked politely, but then he noticed the figure standing next to her. “Oh. Sakura-chan, you’re here too? You missed out on a great mission today.” He added teasingly. 
    
“I heard Sai caught you stealing x-rated jutsus from those pervy ninja’s hideout.” Sakura replied with her own dose of snark. 
    
“Naruto-kun!” Hinata replied gasping in shock.
    
“It’s not what it sounds like!” Naruto tried to explain. “I got them for that dirty old hermit. You know… As incentive to teach me new stuff.” Naruto explained matter-of-factly.
    
“Are you sure that old creep hasn’t just been rubbing off on you?” Sakura asked teasingly. 
    
“Of course I am sure!” Naruto shot back defiantly, but then his defiance faltered as he felt some of his stitches pop in the sides of his jacket. Whatever was happening to him seemed to be speeding up. Naruto started to cross his arms in front of his chest, but noticed that that was causing his jacket to ride up over his belly. He quickly shoved his hands into the side pockets of his jacket in an effort to keep his expanding gut under wraps. 
    
Sakura got immediately suspicious of Naruto’s actions. It was very rare that he would back down from her playful ribbings so easily, and the way he was standing was very much not like him at all. She had never known Naruto to hunch down like he was doing now. It was almost as if he was hiding something. A quick scan over her friend’s body revealed that the front of Naruto’s jacket was packed full of something. Sakura wasn’t about to let Naruto sneak past her so easily. “Hey, Naruto.” She said playfully. “What have you got in your jacket?” 
    
“My stomach. What do you think?” Naruto shot back. As odd as it was, the answer was true, and by saying it outright like that, he knew there was no way Sakura would believe it.
    
“Don’t be that way. We’ve been friends forever. You can trust me with your little secret.” Sakura continued to playfully pry. 
    
“Just bug off!” Naruto shouted back testily. He made a motion to shove Sakura out of the way, but as soon as he pulled his hands out of his pockets, his jacket slid up over his expanding belly. Even Naruto was surprised by the size of it now. It had gone from being the size of a soccer ball to the size of a large beach ball in a matter of minutes. He was too shocked to move as Sakura’s eyes fell on the massive blimp that was her teammate’s enlarged belly. 
    
Naruto looked pleadingly at Sakura and then back at Hinata. To his surprise Hinata was not focused on his belly, but rather what was right below. Hinata’s face turned bright red as she stared directly at the already huge and still swelling bulge in Naruto’s pants. “Naruto-kun…” She said meekly
    
Naruto was too shocked to move or say anything. Whatever was happening, he was already busted, and he could feel the changes ramping up yet again. The stitches in his clothing popped faster and faster as his growing body parts exceeded the maximum capacity of his clothes. His jacket had long since rolled up over his gut and was not stretching and warping into an orange and black, sleeved sports bra for his humongous jugs. His swelling boobs were getting to be more than even his jacket could handle as the stitches began to pop. His pants were faring no better under the combined onslaught of his expanding ass and swelling package. The strain on the front of his pants against his junk was causing him severe discomfort. He was actually relieved when finally his pants fell away in tatters, allowing his massive basketball sized nuts and three foot long cock flop free. 
    
He actually breathed a sigh of relief when his jacket finally burst too. He was now standing bare-ass naked in the middle of the crowded shopping district, but he didn’t care. It was far better than suffocating to death under the strain of his own enormous rack. He looked down and lifted his two jumbo tatas experimentally. It was the first time he had actually seen his chest since the changes started, and he had to admit he had a petty amazing rack. He was surprised to find that he had a set of tits, but he knew that there was nothing else they could be. The steady streams of milk seeping out of his twin nipples proved beyond a shadow of a doubt that he had two, massive, shapely breasts sprouting from his chest. Each hefty bazoom was far larger than is own head. Yet despite their size, they remained pert and perky. Naruto gave them an experimental squeeze. The sensation sent shudders through his whole body.  He didn’t understand why his women friends always complained about their boobs. The set he had now felt amazing.  
    
Naruto’s eyes canvassed the rest of his now nude form. He was impressed by what he saw. He was huge all over and still getting bigger. His immense gut was already three times wider than his slender, toned waistline. It was so huge that he couldn’t even reach his hands all the way around it nor could he see anything below it. Even though he couldn’t see his cock and balls, he knew those were enormous as well. He could feel his enlarged nuts slapping against the inside of his thighs, almost down to his knees, and his cock had to be absolutely gigantic as well. His dick was already hard, but due to his enormous gut pushing down on it, his dick angled downwards instead of up. Even so, he could feel his impressive shaft slapping against the underside of his immense belly. He wished he could reach it and give his cock a pump or two. It felt so amazingly huge and sensitive that he wanted to get off. He didn’t even care that he was in the middle of a crowded street. What Naruto couldn’t see, but it was painfully obvious to everyone else, was hat his rock hard cock was easily as long as his legs and as thick as his waist used to be. The only thing keeping his pre-oozing cock from scraping the ground was the angle that it pointed down at. 
    
Naruto peered back over his shoulder and admired his amazing rump. His ass was simply huge. His butt was now three times wider than his hips had previously been. His cheeks were so huge now that they almost scraped the ground behind him, yet despite their size, his cheeks remained as firm and shapely as ever. He had the world’s most amazing, huge, bubble butt. He reached back and gave his two, massive, pillowy cheeks a squeeze. He was amazed at how supple they were. It was like his fingers could just sink right into the cushiony flesh of his phenomenal ass. 
    
By the time his changes finally seemed to stop, Naruto’s tits were absolutely massive. Each massive jug was the size of beanbag chairs, and his gut was now so humongous that it actually scraped the ground in front of him. Naruto’s dick had fortunately not gotten much longer, but it had definitely gotten thicker, and his nuts had swollen to match. His two huge sacs of cum dangled well below his knees. Each turgid nut was the size of one of those jumbo sized beach party balls. 
    
“What happened to you?” Sakura asked in a voice barely above a hushed whisper. Her eyes were wide with shock and awe. 
    
“You’re the medical ninja, you tell me.” Naruto sassed back halfheartedly. He was enjoying the look and feel of his body far too much to really be angry. Sakura nodded dumbfounded and began to glide her hands over the surface of Naruto’s stomach. What she found made her laugh. 

“What is it?” Naruto asked expectantly.
    
“You’re not gonna believe this.” Sakura replied giddily. “There’s kids in there.” 
    
“What? No way!” Naruto gasped in shock. “Hinata-chan. Can you give me a second opinion?” 
    
“Huh…? Oh.” Hinata managed to reply despite being completely fixated on Naruto’s humongous belly and incredible cock. She had often dreamed of seeing her childhood crush naked, but this was far beyond anything she had ever imagined. She had never been so aroused in her life. She managed to focus long enough to activate her Byakugan. The veins in her temples flared out as she gained enhanced vision of the inner workings of her friend’s chakra. Sure enough, clustered in Naruto’s massive belly were several different energy signatures. There were far too many and they were too clustered together to get an accurate idea of how many were there, but she figured there had to be at least twelve babies forming in her friend’s immense belly. 

Hinata was so fascinated that she couldn’t help but reach out and feel it. She was surprised by how firm Naruto’s gigantic gut was. She could hear the low moans of pleasure coming from Naruto as she rubbed her hands slowly across the vast expanse of exposed skin, but she didn’t fully register what was happening until Naruto began to shudder from her touch.

Naruto had been trying to hold back for what felt like ages. Even though he had accepted that he was huge and nude in public, he had wanted to limit the actual impact it would have on his reputation. The whole growing process had felt so amazing, though, that it had taken everything he had just to keep from creaming the streets with his jizz. Feeling Sakura rub her had across his blissfully swollen belly had almost done him in, but now that Hinata had joined in and begun massaging his super sensitive gut on the other side, there was no way he could stop it. He let out a long, low sigh of bliss as he felt his cock buck and shudder. Within seconds his nuts had seized up and begun dumping their contents along the crowded streets. Massive burst of jizz erupted from his cock with each shudder. Each gigantic cum shot seemed to feel even more amazing than the last. His seed quickly filled the street as it flowed outwards. Even Naruto was amazed by the sheer volume of cum that was stored up in his enlarged nuts. He had expected to run dry after three, maybe four, shots, but he was well past his twelfth load before the stream started to dwindle. By the time he was done, he and his two friends were now standing in an ankle deep pool of spunk. Naruto let out a long, contented sigh of relief. He didn’t really mind that his feet were basting in his own jizz. Nor did he mind that his enlarged gut, ass, and now momentarily soft cock were also dipping into the pool. He was just so glad to have finally gotten off, but he could already feel his nuts slowly filling again. It wouldn’t be long before he’d need to cum again and again.
    
Sakura flung an arm over Naruto’s shoulder amiably as she continued to laugh. “Alright, mama. I think what you need is plenty of bed rest and lots of food, and maybe a well irrigated room. Man though, am I glad I am not you right now. It’s going to be rough living this down. Cumming from just a little tummy rub?” Sakura continued to tease as she poked Naruto’s belly playfully. 
    
Something snapped in the back of Naruto’s mind. He knew Sakura didn’t mean anything by it. They had been friends for what seemed like forever and they never missed a chance for a little good-natured ribbing, but Naruto was feeling strangely vulnerable at the moment. He knew he shouldn’t take it so hard, but he felt the need to get even somehow. Before he even knew it he was already putting the final hand seal on the incantation. He reached down and shoved the palm of either hand into the abdomen of the girls that were standing on either side of him. 
    
Sakura staggered backwards a few steps as the warmth pulsed through her. She had never been so aroused in her life, which when considering how turned on she was by the sight of her nude, enhanced friend, was a very impressive feat. She had always thought that Naruto was kind of hot, but she had never made any moves on him. Now that she had seen him in all is nude glory with those great tits, that amazing belly, that phenomenal ass, and that absolutely glorious cock, she couldn’t even hope to drown out her arousal. Her panties were getting more than a little moist as she tried to playfully tease her friend to hide her feelings, but now those feelings were being amplified. Her panties were getting soaked clear through as she entered new and previously unexperienced levels of arousal. 
    
Hinata was in a similar situation, but she had made it no secret how attracted to Naruto she was. Now that whatever jutsu he had used had been cast on her, she was unable to do anything but let out a sensual whimper as she quickly brought her hands down to cover he soaked crotch. She could already feel her clothes stretching and straining against her rapidly expanding form. “Naruto-kun… why?” She managed to ask between gasps. 
    
“I’m sorry, Hinata-chan. I just got so worked up. I didn’t mean to.” Naruto pleaded with the pale, dark haired girl. 
    
“What about me, dumbass!” Sakura managed to grunt between her labored breaths, 
    
“Well you actually deserved it!” Naruto snapped back. 
    
Sakura didn’t want to admit that this was the best she had ever felt. The changes had only just begun for her and yet she knew that she was going to be experiencing the same growth as Naruto. Her clothes were much thinner and more form fitting than either of her friends’ clothes had been, and so she was already seeing the effects of her changes. Her previously small boobs were expanding rapidly, filling out the front of her pink blouse and then some. Her stomach was bulging out like she had swallowed a bowling ball whole. Her butt was straining hard against the fabric of her short skirt. The strangest change was happening down below though. She reached her hands down both in an effort to hide her wetness and to feel her incredibly stimulated pussy. She could actually feel her snatch swelling alongside the rest of her. She could feel her vagina getting deeper and wider and thicker. She could actually feel her hips spreading wider to accommodate her steadily growing cunt. 

To top it all off, her clit was swelling right alongside the rest of her erogenous zones. She could feel her formerly tiny nub stretch and expand until she could wrap her hand around it. She was so amazed by how incredibly wonderful it felt that she completely forget about her situation or her surroundings and continued to stroke her clit as it grew and shifted. She could actually feel it transforming in the palm of her hand. The now elongated shaft took on a much fleshier feeling to it. She could feel veins forming on the side of her fleshy shaft. She could feel the blood pumping through it. She could feel something new, too, something that she couldn’t really describe. There was a weight at the base of her now massive clit. She reached down with her other hand and felt around. Her breath caught in her throat as she realized what she was feeling. Attached to the base of her now huge, erect clit was a fleshy sack filled with two, large, softball sized testes. She gently gave the closer one a gentle, exploratory squeeze to be absolutely sure. She could actually feel the cum churning inside. 

Her other hand moved its way up the shaft and felt the tip. To her surprise she found that the head of her shaft was completely covered in loose skin. She slowly pulled back on the skin to reveal the soft, glistening head of her newly formed cock. A shiver of pleasure ran down her spine as she rubbed a finger along the oozing slit. She brought her hand back up to her face and stared in awe at the clear, slimy liquid that coated her hand. She still couldn’t believe that she now had a dick, but it was hard to deny it now that her hand was coated in her own pre. 
    
Hinata stared at Sakura in awe as her pink haired friend’s clothes burst, leaving her completely nude and growing in the middle of the street. Hinata’s own clothes were much roomier and afforded her a little more time for modesty, but Hinata could already tell that it wouldn’t be long before her own clothes gave up the ghost. Sure enough, the stitches on her pants were already bursting as her ass got larger and larger. Her undershirt was the first to go, but her sweatshirt followed soon after. Having started with the largest rack of the trio, it was no surprise that hers were growing faster than Sakura’s. Hinata noticed Sakura eyeing her jealously even though Sakura now had the third largest tits in town. Only Naruto and Hinata had her beat now. 
    
Hinata’s eyes fell on the growing shaft below Sakura’s expanding gut. Hinata knew that Sakura couldn’t see it, but judging by the way Sakura was running her hand along it, it was obvious that Sakura knew she now had a fully functional set of cock and balls. Hinata could only gasp as she felt the tightness increasing in the front of her pants. She didn’t want to believe it but after seeing what had happened to her two friends there was no sense in denying it. As her pants finally burst into shreds under the force of her expanding frame, her own newly sprung cock burst free. Her now rigid foot long cock splattered pre in front of her as it bobbed and flung free. Even despite her shame, she was so aroused that her newly formed cock was oozing liquid almost as much as her sopping pussy. 
    
Right as her cock flopped free, Naruto turned to look at Hinata. Time seemed to slow down to a crawl as she noticed her crush’s gaze turn towards her. His beautiful blue eyes dropped down low and stared directly at the hug set of cock and balls that she had sprouting between her legs. She buried her face under her hands to try and hide her shame, but she could still feel all the eyes on her, especially Naruto’s. 
    
“Hey, Hinata-chan. Don’t worry. It looks great on you.” Naruto said reassuringly as he flashed her his most award winning smile he could muster. 
    
“You really think so…?” She asked uncertainly. 
    
“Believe it!” Naruto replied with a cheesy grin. His stupid slogan and goofy grin completely eroded Hinata’s shame. She only cared about what Naruto thought of her now, and if Naruto wanted to see her, then she’d let him see all of her. She crossed her hands behind her back and jutted out her already massive rack for Naruto’s viewing pleasure. Judging by the size of her belly, she was nowhere near done growing yet, but her enormous jugs were very close to matching Naruto’s size tit for tat. As she continued to swell and swell milk overflowed from her nipples and pre flowed freely from her cock. Se could only imagine how absurd and obscene she must look, but Naruto found her beautiful and that was all that mattered. 
    
She was so overcome with emotions and new sensations that she didn’t even know what was happening until it was too late. The more Naruto stared at her longingly the more this strange pressure seemed to well up in her newly formed dick. It wasn’t until her now two foot long cock began to shudder and lurch that she realized what it was she was feeling. Her two, large, soccer ball sized nuts began to seize up, and her mind clouded over from the sheer unbridled ecstasy she was feeling. All she could do was moan loudly in between gasps for breath as large jets of cum launched out of her newly formed cock. Her thick, sticky loads landed with a splat into the already cum soaked road. As her arousal reached maximum levels she could feel her changes really ramp up. She continued to swell and swell as she fired shot after gooey shot of cum into the soggy street. 
    
“No! Don’t do that!” Sakura tried to cry out as Hinata began to spray her jizz into the road. Sakura had been watching both Naruto and Hinata and she could see that Naruto wasn’t going to last much longer. Hinata’s torrent of spunk was the straw that broke the camel’s back. Now that Hinata was cumming, Naruto couldn’t hold back either. His already replenished nuts drained rapidly as he too began to paint the road white with his cream. Sakura had been trying to maintain a level head and be the sensible one of the group, but she couldn’t help it. Naruto’s massive magnificent cock erupting like a geyser was the hottest thing she had seen all day, and her newly formed dick was begging for release. Sakura tried to bite her lip and keep herself from making herself look like more of a fool tan she knew she must already appear by not screaming in ecstasy, but by the second spurt she was shouting in pure euphoria. She had just never imagined it could feel so good. It wasn’t just the cumming either. Her whole body expanded outwards so pleasantly. It was like every inch of her skin was aroused. 
    
By the time the three had finished pouring out the hefty loads into the crowded city street, their growths had finally topped off. Hinata easily had the others beat for breast size with Sakura in second, but Naruto’s enormous dong was far bigger than either of the girls; his cock was now pushing four feet long and was far thicker than his waist had been before the changes had occurred. His umongous, beanbag chair sized nuts sat heavily on the ground even though he was standing upright. All three of them had absolutely enormous asses that were almost four times as wide as their hips had been before he changes. Their large, shapely cheeks managed to keep their firm and perky shape despite being so large that they scraped the ground. All three of them had gigantic stomachs that were every bit as wide as their asses and protruded out in front of them quite a few feet. Their guts were so large and so heavy that they rested solidly on the ground before them. They couldn’t even see over the crest of their enormous bellies. 
    
“Oof. I don’t think I can even move.” Naruto moaned. 
    
“I think I can… barely…” Hinata muttered. 
    
“Looks like no missions for us until this runs its course.” Naruto said matter-of-factly. “At least it’ll be over soon. I mean it took us only a few minutes to get this big, right?”    
    
“You dummie!” Sakura shouted testily at Naruto. “This is barely even the first trimester, and the changes have dropped off altogether! It’s going to take us months to have these kids!” 
    
“Oh.” Naruto replied, strangely calmly. He didn’t say it out loud, but he was actually excited for what the next few months would bring. He stroked his belly tenderly as he felt his massive cock steadily chubbing up beneath his enormous belly. He just knew his gut was going to be absolutely gargantuan by the time he reached his due date.
