Chapter 1 - The side effects of Sakura's new breasts!

Sakura was a nervous wreck. Despite finally succeeding in marrying the man of her dreams, she was still extremely shy around him. As per usual, Sasuke was away from home, nobody is certain what exactly he was doing or trying to accomplish. Since he was hardly ever home and able to spend time with his family, Sakura was brimming with excitement when she received a letter that was sent by Sasuke.


Sakura excitedly opened the letter and read aloud the message that was written on it. 


“Sakura, I plan on coming back home in a few weeks to celebrate Sarada’s birthday with everyone. Make sure to keep this a secret from her.” 


Sakura let out a girly squeal, accidentally crumpling the letter in her hands as she celebrated Sasuke’s much anticipated return back to the village. 


“Finally, Sasuke-kun’s coming back home! It feels like it’s been forever since I’ve seen him.”


--------------------------------------------------------------------


Sakura hops out of the shower, gently humming a pleasant tune to herself as she imagined the scene of Sasuke embracing her when she finally gets to see him again. As she catches a glimpse of her naked body in the mirror, Sakura feels a little bit self conscious as she examines her body, the worrying feeling of not looking appealing enough to Sasuke slowly creeping into her mind.


She places both of her hands on her slim waist, satisfied with how tight it was. Her hands begin to descend until they were placed on her womanly hips. 


“I don’t mean to gloat, but I really like how wide my hips are.”


Sakura twisted her body around, keeping her eyes on the mirror as she tried to get a cleaner view of her plump ass. She gave her butt a light shake, watching the reflection of her ass jiggle rapidly. 


“Looks like I still got it, even my ass looks damn good. It’s probably the best in the village, in all honesty.”


The smile on her face slowly disappeared as her eyes focused on her chest. Even since her academy days, her boobs were always considered quite small, especially in comparison with the other woman in the village. It tormented her daily, with every woman that she converses with on a daily basis possessing an impressive rack. Sometimes when she used to train with Tsunade, her large tits bouncing around distracted her, making her feel jealous that she wasn’t blessed with an ample breast size.


“And… I still have a problem in this department. I don’t get how the other girls do it? Why is reality so cruel that I’m the only woman in the village stuck with such tiny tits!”




Sakura cupped her A-sized breasts, and tried to squish them together. The disappointment on her face evident as she was reminded of her only weakness in terms of her sexual appeal. It wasn’t like her body remained the same since she was a teenager, either. Her figure grew increasingly voluptuous, her ass growing substantially bigger, her hips were wide and appealing, and her waist was thin in comparison to her body. So, why couldn’t her tits receive the same treatment? It wasn’t like she found herself unattractive, but her underdeveloped breasts always caused her to subconsciously feel inferior to the other women around her, even though that wasn’t the case.


Sometimes, her insecurity would cause wild delusions to form in her head, with her beloved Sasuke leaving her for another woman with big breasts. When these painful thoughts would surface, Sakura would always be sent into a depressed mood, wallowing in her self pity as she cursed herself for having such small breasts. 


This time however, her reaction was different. Sasuke was set to return in just a few weeks, and she wanted to do something about her mediocre chest as a surprise for her lovely husband. 


“I guess I have no choice.. There’s only one person that I could go to that could help me with this.”


A determined Sakura vowed to change herself for the better, and decided to confide in the most knowledgeable woman when it came to breast sizes. 


----------------------------------------------------------------------------------------


Sakura nervously knocked on the wooden door, still contemplating in her head whether or not she was making the right decision. After a few seconds of waiting for an answer, she shook her head and reconfirmed to herself that she would look as sexy possible for Sasuke. 


“I want Sasuke-kun to think I look sexy, so… I have to do this!”


Sakura, who was in the middle of pumping her fist in the air to psyche herself up, was abruptly interrupted by the sound of the wooden door swinging open.


“Sakura? What is it?


“Sensei! Um.. Can I come in? I have something urgent to talk to you about!”


“Of course, Sakura. What’s so important that you’d have to come over for?


Tsunade let Sakura enter the house, the two girls settling down and sitting on the couch. 


“Well.. I was wondering if there was any way that you could make my chest bigger?”
Tsunade, who had just picked up a glass of water, nearly spat it out as she was in the middle of taking a sip. 


“Why would you think that I could make your chest grow?”


“Well.. Looking at how big you are.. I thought that you’d be the best person to ask, after all, there’s no way those are real, right?”


Sakura pointed her finger at Tsunade’s massive boobs, causing the ex-hokage to get slightly irritated.


“W-what?! I’ll have you know these are completely natural! These took me several years to grow to the F-sized cups they are now!”


“No way! I thought those were the result of that jutsu that make you look young!”



“Huh? As if, even without using any jutsu, these huge knockers of mine would still be this big.” said Tsunade, pressing them together with an annoyed expression on her face.


Sakura frowned, feeling disappointed that there was nothing that could solve her dilemma.


“So, there’s no way you could help me, sensei?”


“.... Well, there is one jutsu that I’ve learned about. But I don’t know if it’s safe, I’ve never-”


“Yes! Please, sensei! Tell me!”


“Hold on, don’t get too excited now! It’s a jutsu that was specifically made for strippers, it expands the size of a woman’s breasts, and-”


“Perfect! That’s exactly what I’m looking for! Hurry, Tsunade-sensei, use it on me!”


Tsunade held both of her hands out, signaling at Sakura to try and calm down a bit as she explained everything about the forbidden jutsu that she knew about.


“Alright, alright! I’ll use it on you. Just be warned, I’m not certain if there are any side effects to the jutsu, I’ve only learned it out of pure curiosity and I’ve never actually used it on anyone.”


“That’s fine with me!”


“Also, the change isn’t instant, it’s said it could take a few days or weeks before fully taking effect.”


Sakura excitedly nodded her head, already starting to lay down so that Tsunade could perform the jutsu on her. 


Tsunade sighed loudly as she stood up to position herself beside Sakura, hovering over her as she prepared to use her breast expansion jutsu. 


“Don’t get mad at me if something happens, okay?” warned Tsunade.


“Of course, just do it already.”


“Alright then, I hope this is worth it, Sakura.”


Tsunade placed both of her palms over Sakura’s chest after weaving the hand signs required to perform the jutsu, and after a few moments, chakra began to travel its way from Tsunade’s palms and into Sakura’s chest. 


“There, all done, Sakura. Is that all?”


“Yes! Thank you so much, Tsunade! You have no idea how much this means to me!”


Sakura lunged at Tsunade, holding her friend and sensei in a tight embrace. Tsunade smiled as she patted her back, glad to have helped her out in her time of need. 


----------------------------------------------------------------------


The process of the breast-expansion jutsu produced alarming results. After a few days had passed, Sakura was originally content with the results. Her mere A-cups had grown to the acceptable size of C-cups. The only drawback that she immediately noticed however, was that it seemed as if her nipples were almost permanently hard. While this proved to be annoying at times, Sakura was fine with this being the only side effect if it meant having a bigger chest to better suit her body.


After the first week passed by, her chest grew at an insanely high rate, and her boobs grew substantially and now required DD cups to contain them. Sakura was now constantly checking herself out in the mirror, loving the look of her perfectly curvy voluptuous form, her huge tits complimenting the rest of her lovable assets well. At this point, whenever she was spending time outside the house, to either buy groceries or go shopping, she noticed that there would be a lot of eyes ogling her chest as she walked by.


Sakura wasn’t exactly foreign to this type of behavior, but after her tits were this huge, she couldn’t go thirty seconds without catching another man from the corner of her sight eyeing down her boobs. Sakura swore that she could hear the faint whispers of chatter behind her back when she would pass by other woman, clearly jealous of her impressive bust. 


“Oh my god, I look so sexy! Sasuke’s going to love my tits! There’s no way he’d ever leave the village again after he sees how big my breasts are!”


Sakura placed her right hand underneath her tit, pressing it upwards to see it jiggle. 


“Amazing! There’s absolutely no sag to them! My boobs are perfect right now! Thank you so much, Tsunade-sensei!”


---------------------------------------------------------------------


As the second week ended, her already huge tits grew almost disproportionately from her body as her cup size was now improved to an impossible G-cup. It was starting to alarm Sakura how much her tits have grown, and when she tried to confide Tsunade for help, she was let down as Tsunade was now away from the village for an indefinite amount of time to go gambling. 


Sakura was now stuck with her abnormally huge tits, which was now becoming a hassle to keep up with. It was already difficult enough to find stores that sold her previous bra-sizes, but now that they grew this large, she had to pay extra to have them custom-made. Since she always had a small chest, she wasn’t even aware that this was possible, she started to feel sympathy for Tsunade as she griped to herself about the inconveniences of enormous titties. 


Since she was having trouble finding a place that could provide her with bras, Sakura decided to just stop wearing them completely. It embarrassed her to walk around town with her massive boobs flopping around everywhere, unbound by the tight constraints of her bra, as well as her perky nipples clearly popping out of her shirt. However, she noticed that the only benefit of having boobs this big was that the men surrounding her were much nicer to her. Albeit, she was aware that they were staring at her cleavage that boasted the size of her bust.


Sakura sighed to herself after enduring yet another long day at work, finally happy to reach the final appointment of the day. She wasn’t sure if it was a side effect of the jutsu, or maybe caused by her new appearance, but Sakura was feeling increasingly horny as the days passed by and was beginning to crave sex. Her pussy ached with an intolerable itch as she started to cross her leg, hoping to conceal her apparent horniness. She slowly started to rub her crotch, trying to ease the itch and hopefully calm down a bit before her final patient walks in. 


“Ah!”


Sakura dropped her clipboard and yelped in surprise as the door behind her suddenly opened. 


“Oops, sorry, Sakura! I didn’t mean to startle you.” 


“Oh, don’t worry about it, it’s alright!” 


Sakura’s face was flushed, she was on the brink of release until the old man walked into the room. Her heart was beating insanely fast, scared to death if he ended up catching a glimpse of her pleasuring herself while she was supposed to be working. 


The elderly man laid down onto the bed, crossing his arms behind his head as he looked at Sakura. 


“Say, Sakura-chan.”


“Y-yes?”


“Is it just me, or have you grown a lot recently?”


“Oh, yeah.. I’ve been getting that a lot recently, haha.”


Sakura tried to wave off his perverted comments, trying to direct his focus elsewhere. 


“How did you do it, Sakura?”


“Do what?”


“How did you get your breasts to be that large? They’re enormous! I haven’t seen anything like them! The last time I’ve seen you, they weren’t even close to that size!” said the old man, marveling at her beauty while openly ogling her cleavage.


Sakura blushed at his sexual comments, her fingers and legs now fidgeting at the awkward situation. 


“Um.. If it’s alright with you, I’d like to continue with the examination.”


“Of course, of course! I didn’t mean to make you uncomfortable, princess!” 


Sakura smiled as she moved her chair next to him, preparing to commence with her monthly examination. She was required to lean over him as she inspected his chest, lifting his shirt up in the process to place the equipment directly on his skin. As she was trying to focus solely on the examination, the old man didn’t make a single effort in hiding his actions, practically drooling as he shamelessly checked out Sakura’s body. 


She didn’t want to make a big deal out of it, but it was certainly taking a toll on her body. Having the old man stare at her chest so openly was causing her to feel even more horny than she already was, her panties now soaked with her vaginal fluids. 


“My, my, you certainly are pretty, Sakura-chan.”


“Oh.. Thank you, sir..”


Sakura paused the examination momentarily, and stood up to grab something from the drawer. The old man cat whistled as he checked out her ass, loving how her fat rump was outlined with the thin fabric of her work dress.


“I never noticed, but you’ve got a nice ass too, Sakura-chan. If only I were younger, maybe you could be my girlfriend!”


 Sakura kept her head down and blushed, trying to ignore his sexual advancements on her. “Don’t be silly, haha.” she nervously chuckled. 


Sakura continued her examination, beginning to lightly massage his legs starting from his calves and slowly progressed up his thighs. In a daze, she continued to rub her palm against his legs, until her hand suddenly touched something very warm and sturdy. 


“What was that, it almost felt like a-”


Sakura blushed profusely as she averted her eyes to the hot object she accidentally grazed with her hands when examining his thighs. She gasped as she noticed the old man was sporting a massive hard-on underneath his shorts, a very apparent bulge appearing on his tight beige shorts. 


“Oh my… It’s so big.. I’ve never seen one that large before.. It might even be bigger than Sasuke’s..”


“S-sorry, I didn’t mean to..”


“It’s quite alright, Sakura-chan. Being the old man that I am, this type of thing happens to me when I’m surrounded by such beautiful women.”


“Ah.. Well, I’m sorry to hear that?.. I guess. Um, well I’m finished the examination.. There’s nothing wrong with your body. Except for-”


Sakura cut herself off as she almost referred to his abnormally large penis as a health issue. 


“Nevermind, you’re all set to go! Well, I’ll be taking my leave now.”


Sakura bowed her head as she rushed to gather her belongings, wanting to get out of the room as soon as possible to furiously finger herself to completion in the washroom.


“Wait, Sakura-chan.” 


“Yes, what is it?”


“I think something’s wrong with my body, could you help me out with this?”


“What’s wrong with your-”
Sakura was cut off when the old man pointed at the bulge in his shorts, slowly rubbing it with the palm of his hand. 


“Sorry, Sakura-chan. Like I said earlier, I can’t really handle myself around pretty girls.. Whenever my penis gets like this, it won’t go back to normal unless I cum everything out..”


“Oh my.. That definitely sounds like a health problem..”


“Could you examine it for me?”


“I.. I’m not sure if I can..”


“You’re a doctor, aren’t you, Sakura-chan?”


“I am.. But this is... “


“You know, when Tsunade was my doctor, she’d always take care of it for me..”


“Take care of it? You mean she..”


“That’s right! Tsunade would help me cum after every examination!”


The old man was already zipping down his shorts, kicking them off using his legs. Sakura gasped in surprise as she got a better view of his cock, his old boxers hardly being able to contain his length. There was a noticeable dampness on the tip of his cock, signaling how horny he was with the amount of pre-cum that had already formed. 


Sakura remained silent as she couldn’t stray her eyes away from his cock. 


“Sakura-chan.. I don’t mean to bother you.. But could you help me out? Tsunade told me that if I don’t get rid of it after a few days.. I might even die..”


“Die? There’s no way that’s true! This old man just wants me to get him off! But.. I’m not sure if he’s telling the truth or not.. I better play it safe than sorry.. Plus, Tsunade would probably do the same thing, right? It’s just a massage, that’s all. I’m just going to be massaging him with my hands.”


Sakura tried to convince herself that what she was about to do wasn’t wrong. She had felt so horny over the past few weeks that seeing the cock of an old man was actually exciting her, though she didn’t want to admit it. 


“Alright.. I understand.. Just let me know when you’re letting it out, okay?”


“Yes! Thank you, Sakura-chan! You’re the best!” 


The old man scooted over to her, his legs now dangling off the mattress as he sat down in front of her. Sakura was breathing heavily, mentally preparing herself to see the cock of someone other than Sasuke. She took a loud gulp when her fingers slid underneath the fabric of his boxers, slowly pulling them down towards his knees. His impressively large cock sprung free as it lightly slapped her face, causing Sakura to turn her head away in surprise.


“Wow.. He’s so big… I’ve only seen Sasuke’s but.. This old man might be even bigger than him..”


Sakura reluctantly reached her hand towards his cock, hesitantly wrapping her fingers around it. She blushed when she made eye contact with the old man, who started to groan when she began stroking him up and down. Her pace was slow, being the first time she’s ever had any source of sexual interaction with someone else. 


Sakura was uncomfortable with the entire situation, yet it still excited her to know that she was capable of making a man feel good. 


“Yes… Sakura-chan.. Faster.. Move your hands faster..”


Sakura silently nodded her head as she increased the speed of her strokes, earning a slight moan from the old man. Feeling encouraged by his moans, Sakura started to use both of her hands in tandem, moving them in a twisting motion as she increased the passion of her handjob. 


“It’s a bit dry, Sakura-chan.. Could you spit on it for me?”


“Yes.. of course..”


Sakura’s eyes grew wide as her face drew closer to his cock, hovering over the head as she gathered her saliva and spat on his cock.


“Mmm.. that’s better..”


The room was now silent other than the wet noises of Sakura’s wet handjob, his cock now glistening from both pre-cum and Sakura’s saliva. The old man was starting to feel the pleasure of her skilled handjob, and wanting more, reached his hand over to grab a handful of her breasts.


“Oh my, Sakura-chan! These feel as soft as they look!”


“Ah.. don’t touch there..”


Sakura whispered, trying to trick herself  when in reality she loved the feeling of him groping her. 


The old man started to fondle her, kneading the bouncy flesh of her soft mounds. 
“I’m sorry, Sakura-chan.. Your hand feels really good, but I’m afraid it’s not enough..”


“Eh.? What are you saying?”


“We could be here all day.. If you want to finish quicker..  Maybe you could use these big breasts of yours?”


The old man roughly squeezed her tit when mentioning the term “big”, emphasizing his point. 


“I don’t know.. No one other than my husband has seen them before..”


“Well… Have you touched the cock of another man before, missy? That’s what you’re doing now, aren’t you?”


“No.. This is only a massage.. I’m just trying to help a patient of mine in need..”


“You don’t have to lie to yourself, Sakura-chan. Come on, take that top off for me..”


The old man pinched her nipples, eliciting a moan from Sakura. She paused for a moment, sighing in defeat as she removed both of her hands from his cock and lifted her top off. The old man’s jaw dropped in awe at Sakura’s beautiful form, her massive bust being the biggest he’s ever seen, even surpassing Tsunade in that department. Her skin was clear and almost shiny, her big pink nipples looked ripe for sucking. 


“Oh my goodness, Sakura-chan! You’re beautiful! Your boobs.. They’re.. So big! They look even better than Tsunade’s!”


“T-thank you..” 


Sakura was elated at his compliment, finally receiving praise for her intensely erotic chest, something that had never happened to her prior. 


“Come on, come on! Let’s do it, already!”


The old man pulled at her shoulders, urging her to get closer to him. Sakura followed his instructions and leaned closer to him, his long cock standing proudly before being engulfed by her tits. 


“Ohhhhhh…. My god…. Sakura-chan!”


The old man moaned loudly, not caring if anyone was around to hear his voice. He clasped his hands tightly around the sides of her boobs, fondling them and pushing them together to tighten her grip around his cock. The elasticity of her tits amazed him, and getting lost into the sensation of pure boobage, the old man began to thrust wildly into the depths of her cleavage. 


“You’re sucking me in, Sakura-chan! I can hardly even see my cock anymore!”


The old man breathed heavily as he started to mindlessly thrust into her breasts, only the tip of his cock could be seen momentarily popping out of her seemingly endless cleavage. Sakura felt so turned on at this point, loving the taboo feeling of getting another man off with a chest that she so desperately coveted. 


“Yes.. Cum.. Give me your cum..” panted Sakura, her face glued to the sight of his cock disappearing into the depths of her enormous boobs.


“Oh, what’s this, Sakura-chan? Finally getting in the mood?”


The old man removed his hands from her tits, allowing her to do all of the work while he rested his hands on the top of her head, caressing her pretty pink hair. After enduring her handjob for a while, the old man was finally approaching his release. 


Sakura was beginning to sweat, starting to grow progressively more fatigued from having to work her breasts over his cock. She was alternating between shoving her tits together, squeezing him tightly inside of her cleavage, and stroking him rapidly up and down using the soft flesh of her new tits. This torturous cycle of her erotic paizuri was proving to be too much for the old man to handle, his face scrunching in pleasure as he threw his head backwards. 


She wasn’t given a warning, so Sakura wasn’t prepared when she felt the old man’s cock throb and the sudden bursts of cum spray out of her cleavage. Sakura yelped in surprise and closed her eyes, as the large fountain of semen landed on top of her breasts, coating it with his spunk. Sakura turned in the other direction, facing away from his cock as to not get any of it on her pretty face. 


“Yes… Oh, yes! Sakura-chan, these tits are unreal!”


The old man squeezed them one last time, urging on his ejaculation. A portion of his cum landed on her hair and chin, much to her disappointment. After a few more seconds, Sakura’s tits were finally released from his tight grip as he finally finished cumming. There was a silence that took over the room as the old man struggled to keep his breath, his head turned up at the ceiling and thanking the heavens for allowing him to feel such pleasure. 


Sakura’s panties were drenched, glad that she finally managed to make him cum, so she could deal with the unbearable itch on her crotch. 


“Alright.. There you go.. I hope you enjoyed it.. I’ll be leav-”


Her voice was suddenly cut short when her mouth was filled with the old man’s cock in an instant. He yanked her head forward and shoved his long cock into her mouth in the middle of her speaking.


“Sorry, Sakura-chan. It looks like i’m still raring to go, so you’re going to have to bear with me for a second!”


Sakura tried to reply, but her mouth was occupied with his large seven inch cock that was now beginning to thrust into her wet orifice, threatening to get deeper inside with each push of his hips. She immediately reached one of her hands underneath her dress, unable to cope with the tingling sensation any longer. Sakura started to furiously finger herself, the wet noises of her vagina as well as her forced blowjob filling the room. 


The old man groaned when he felt the vibration of Sakura moaning around his cock, loving the feeling of her wet warm mouth salivating around his shaft. He shifted his hands onto the back of her head, and roughly pulled her forward to take his cock into her tight throat. Sakura gagged profusely when he entered her throat, having never performed one on Sasuke before. 


Sakura forced her eyes shut as the old man started to bob her head in the rhythm he desired. Her vaginal fluids began gushing out as her face was now getting fucked, loving the feeling of pain in her throat and the dirty taste of his manly cock. Sakura was previously just allowing him to fuck her face, but after getting used to deepthroating him, she began to bob her head at her own will, meeting his powerful thrusts into her virgin throat. 


“Yes! That’s it, Sakura-chan! Just like that, keep going!”


Encouraged by his praise, Sakura shoved her head forward and took him as deep as she could, his pubic bone smacking against her nose. Her throat constricted around his cock, and caused her to choke furiously, spittle drooping out of her mouth as she kept her head on his crotch, her plump lips kissing his pubic bone. 


“Phenomenal! Sakura-chan.. I can’t hold it in any longer!” 


The old man shouted in pleasure, grunting loudly as he held her head down and thrusted violently into her throat. Tears began to form around Sakura’s eyes as she shut her them tight, the feeling of his cock invading her throat leading her towards her release. The throaty noises of her face being fucked could be heard in the hallways, as Sakura tried her hardest to inhale his cock and prepared herself to swallow his semen.


“I’m cumming, Sakura-chan! Swallow it! Swallow it all!”


The old man’s cock throbbed violently into her mouth, signaling it was ready to blow. Multiple waves of cum began shooting out of the tip at frenzied speed, his cum sloshing inside of her throat as it shot directly into her stomach. The old man released her from his tight grip as he sighed in delight, emptying out the contents of his balls into her willing throat. 


The old man was surprised when Sakura started to bob her head, her fingers rubbing herself to completion as she moaned loudly into his cock while experiencing her own orgasm. Sakura moved her lips and tongue around his dick while he continued to shoot his load, which was somehow bigger than the first. Semen spilled out of the corner of her mouth as she clumsily let it slip out of her mouth momentarily, before readjusting her face to take him back inside of her mouth, refusing to let him go until he finished cumming. 


“Sakura-chan, you’re such a good girl!” 


The old man’s cock finally stopped hosing her down with his semen, and he shuddered in pleasure when Sakura lapped at his tip, fully milking him dry.  She gave him a few more bobs of her head, sucking loudly around his cock before taking it out of her mouth, her cheeks full with his cum before she skilfully swallowed all of it after two loud gulps.


Sakura’s tongue hangs out of her mouth as she removed her head from his crotch. Her makeup and face a mess as it was covered in his semen, her chin dripping with her own saliva. 


“Ah.. That was amazing, Sakura-chan. Thank you so much for that, you young women are always helping us old men out!”


He gently patted her head, thanking her for emptying his balls. Sakura didn’t respond as the old man took his leave, satisfied with having his balls drained by such an attractive woman. 
Sakura sat in the afterglow of her paizuri and facefuck, staring at her climax that was sprayed onto the floor. 


“I can’t believe I cheated on my husband like that.. What a wife I am.. Asking for a bigger chest so I could please him.. Yet here I am, having an orgasm over sucking some old man’s cock..” 


Sakura was ashamed of herself, immediately regretting her uncharacteristic decision after calming down from her sexual high. Sakura removed her soaked panties, and headed to the washroom to clean her appearance and head home, her mind filled with nothing but emotions of guilt and shame.


“What would Sasuke do if he found out? Oh… I can’t believe I did that.. Maybe this wasn’t the best idea.. I wasn’t perverted like this for anyone other than Sasuke before I used that jutsu..”
