This fanfiction is a novelization of the work done by Himura Kiseki on Getsuyoubi no Tawawa.

This week was a bit special and Onii-san couldn't stop thinking about it this whole time. This time he would meet his angel on an afternoon instead of the usual Monday morning as she asked him to come visit her at her working place. He vividly remembered her mischievous smile on the train as she told him the address. He didn't why but seeing her outside of their fairly-new Monday routine was enough to make his heart beat faster in anticipation. Of course, her teasing about her surely-striking uniform was no stranger to his excitation. After a few minutes looking for the address, he finally managed to find the location of the small restaurant, fairly aside from the main shopping streets but not too far away either to allow lucky onlookers to find this gem. It was a bakery named "Bakery Restaurant Tawawa". Onii-san chuckled. "Tawawa, uh ?". "Tawawa" was referring to a branch of a tree bending from the weight of abundant fruits. Somehow, he found the name perfectly fitted for something else than this bakery. Or someone else…

Adjusting his necktie, he moved forward, opening the automatic doors. Behind them, a short girl immediately leaned forward. Surprised, he automatically lowered his eyes to the two enormous bulges straining the bakery's uniform. Her braids and smell were also a nice giveaway, making him able to recognize her without having her to get back up. It was her : Ai-chan.

- Welcome ! said the young girl, standing back up.

Ai-chan's face was more beautiful than ever. Her hair was impeccable, carefully braided on her side, even more than ever. Her big green eyes were dazzling as always and started to sparkle with joy and mischief as soon as she recognized him. As always, she was not wearing any makeup : her sheer natural beauty alone was enough to catch the attention. Her amazing lips stretched into a very faint smile when she saw him starting to look down to observe her outfit. She was wearing a close-fitting white and blue waitress uniform that underlined a lot of her curves. Her chest area, by far the most striking one as always, was exalted by the white uniform's shirt, showing the perfect curves of her round and massively plump J-cup breasts. The large creases also did an admirable job to emphasize their tremendous sizes. Just like a few mondays ago, she was wearing a ribbon, albeit way smaller than the previous one to not impair the sight she was offering. Her blue apron was going down from her shoulders all the way down to under her chest, following her large curves, providing (very few) support. The apron tightened once more around her waist, showing her perfect flat belly, underlining again her uniqueness. It spread out again showing her large hips. Onii-san, already dazzled by her chest for the last weeks, never actually noticed how impressive her lower body was and especially her hips, usually hidden in her school skirt. The apron spread into a large skirt, painfully hiding her other curves under it. Her legs were closely fit into black tights, showing how elongated they were even though she was so small. As to her shoes, they were black as well and with a nice cute form and golden buckle on it. Onii-san was sure of it : she was pure perfection, definitely heavily well-endowed for sure, but most of all, she was incredibly cute.

- A party for one? Would you like a smoking table or a non-smoking one? Ai-chan professionally asked, even though her eyes were betraying her pure satisfaction of him looking at her in this outfit.

A bit troubled, Onii-san managed to stutter :

- Uh… ah, uh… a non-smoking t-able… please.

- Understood, please follow me.

Her professional approach was impeccable and that only made her even more attractive as she seemed so unreachable to the whole mortal race. She closed her eyes and her faint smile grew slightly only for him to see as she turned away. Onii-san knew what was coming right before she started doing it. Each time she was closing her eyes and pairing it with that particular smile, he was about to witness something incredible. And he did not wait long to know what it was. Each one of her steps was making her huge chest jiggle heavily. Her clothes and the apron weren't actually providing any support for her chest that was now free to bounce with full force in her clothes. Feeling fire coming to his cheeks, he followed her in the dining room.

The restaurant was cozy and quite nice but he could not help himself to notice all of the waitresses around him. There were only five of them and they were all young teenage big-breasted women, walking around and talking to the clients. He thought for a moment that he arrived in paradise, with all these bountiful breasts bouncing in their aprons. It was rather complicated to know where to look, actually. He followed Ai-chan across the room and quickly focused on her. He actually never saw her much from behind. As he was expecting, the apron's skirt was covering her behind but her large hips' swaying betrayed her charms. Given their considerable height difference, which was around 30 centimeters, Onii-san could perfectly see Ai-chan's considerable chest bouncing heavily from above her shoulders and was delighted to see it from this point of view. They were so big that her small back couldn't hide it sticking out from the sides either. Most of the clients were women and a good part of it, of a certain age. Yet, here and there, he managed to catch the clients' quick glances at her figure, oftenly mixed with amazement, curiosity or (he was sure of it) jealousy. She stopped by a table in a corner of the room where he could see the whole restaurant and gave him the menu. As he was taking it to read, Ai-chan slightly leaned forward towards him on his side, reaching his left ear as she was pouring water in a glass.

- We're getting a batch of fresh bread at around 6 o'clock, so I'll give you a few to take home as a souvenir, she whispered.

- T-thank you, he replied. I…I'm looking forward to it.

She stood back up, waiting for his choice. Onii-san opened the menu and perused through it. Yet, the more he was trying to focus on it, the more his eyes were drawn somewhere else. Ai-chan was quite small, not even reaching 1m50, meaning that her imposing chest was just at his eye level. Being this close next to him, he struggled to not notice the enormous hills of hers, lifting up and down as she breathed. The more he was trying to focus on the menu, the more he was noticing her two mountains as big as his head moving next to him.

- Hum, Ai-chan, excuse me?

- Yes, what is it? she replied with a big joyful smile, bending slightly to hear him.

- I... Hum, I'll call you over when I'm finished choosing, so uh… I'm fine for now.

She looked down on him, her smile vanishing a bit, visibly annoyed.

- Understood, she replied coldly as she straightened her back, sticking out her massive breasts as to show him what he was losing.

She left him to walk away towards the other clients. Onii-san sighed. "You look cute". That's probably what she was waiting for. Onii-san realized it only a second later but she already left, leaving him alone. He was so stupid to have made her annoyed but could not help following her with his eyes, looking at her mountains jiggling heavily in her tight apron. He looked around at the cozy bakery, trying to stop his own eyes to revert back to Ai-chan. As he noticed before, most of the customers were surprisingly women, probably feeling more confident towards each other. It was clear that the theme of this place was to employ only big-breasted girls as waitresses. One could easily see that the sole purpose of their aprons was to greatly emphasize the size of their young breasts by some unknown clever design and management choices. For sure, this place looked like heaven's last kingdom on Earth with so many beauties around.

But amongst all of these young teenagers, one stood out from the rest of them. Of course, it was his beloved Ai-chan. Even in this place, she outshined her well-endowed competitors by her pure beauty but also the sheer amount of volume she was displaying. Her J-cup breasts greatly overcome the E to G-cups of her colleagues with such a great ease. And again, she was by far the prettiest of all of them as well as the cuter with her small slender belly. Onii-san just noticed it but… it looked like she was the only one to exhibit such large creases on her shirt, especially around the buttons on the line of her largest part. As the aprons were designed to make the busts of their owners bigger and rounder, no other girls were displaying such an incredible feat of having creases. Onii-san chuckled. Ai-chan was literally mightier than the mind of a big-breast focused designer who never had thought that a person this slender would have such important masses. Onii-san realized he could not even stop looking at them : they looked simply enormous in this outfit.

Ai-chan's approached a table with a couple. As the boy was asking a question, the busty girl leaned forward towards him. Onii-san felt his heart skip a bit and an ungodly jealousy burning through his veins. The boy tried to keep a straight face but his eyes were automatically drawn in the two large masses leaning towards him. His facial expression greatly betrayed his amazement. As Ai-chan was explaining the menu to him, her short height forced her to lean her massive chest almost to his face, just a few centimeters away. Both of her bigger-than-her-head weapons greatly teased him being this close to his eyes. They were so close that it was almost certain that the parts of his menu were almost completely hidden behind her two mountains. While explaining to him, Ai-chan's imposing bosom knocked a cup of water on the table.

- Oh I'm so sorry ! I'll wipe it right away ! she said.

Taking a tea towel from her apron, she actively wiped the table, making her enormous breasts jiggle right in front of the man who couldn't help but give quick glances to them. Ai-chan innocently passed a strand of hair behind her ear only to look sideways to Onii-san across the whole room. They made eye contact and both of them read into each other's minds. He did not have enough time to simply consider erasing the utter burning jealousy and envy in his eyes to be in the situation of the other man. Seeing that, Ai-chan's look, on the other hand, filled up with mischief and proud arrogance. She had done it on purpose. Once again, she made him fell head-first in her trap : she perfectly succeeded at creating the tease and envy she was looking for. And once again, it included her titanic-sized breasts. She perfectly knew how to play with him. As she finished advising the other boy, she turned around and kept her eyes fixed on Onii-san's ones for a few steps. This time, she accompanied her with a very small and faint impish grin only for Onii-san to see. Her green eyes stared at him with such a powerful teasing and playful look that his whole anger vanished. She left the table, her large mountains bouncing again at her pace to walk back to him. In a simple move, Ai-chan literally made Onii-san crazy about her and he barely overheard the conversation of the couple.

- I… I don't know what you mean… said the boy to his girlfriend, visibly embarrassed.

- We'll talk about it later, she angrily replied, shutting the conversation.

As the amazing teenager arrived at his table, she stopped standing up straight with her large bosom stuck out.

- Is something wrong, mister ? Are you ready to order ?

Onii-san chuckled in disbelief, passing his hand on his face to calm down.

- Oh…uh… I… that one of this cake set.

Ai-chan turned over the table to stand by his side and bent forward above his shoulder. She followed with her finger Onii-chan's one on the menu, taking her order. This time, Onii-san did his best to focus on it. He could feel her monstrously huge bigger-than-his-head breasts just a few millimeters away from his face, hovering above his shoulder. He could feel their presence and incredible perfume which filled the air. If he were to turn his head on his right, he would bury himself in her soft flesh. Ai-chan slightly whispered :

- My shift ends at 7 today. Can you wait for me at the station ?

- S…Sure !

Hours passed and the afternoon was almost over. Onii-san spent it in pure heaven, eating well and following with his eyes her angel. He knew she was the responsible type but she was even more-so when she was working. For once, he could look at her and her stunning side for long minutes. They often looked at each other and exchanged a smile. Well, a lot of these times were just Ai-chan caughting him looking at her breasts. She did not seem to care but Onii-san could not help himself to feel his cheeks blushing in shame. And each time, his eyes would down on them again. They were just so perfectly huge, bouncy, soft, firm, round, healthy, perky… He spent almost the whole afternoon contemplating them and trying to find adjectives to it.

In the late afternoon, Ai-chan came back to him. As she walked towards him, she caught him once again looking at her outfit and she smiled :

- Are you finished ?

- Yes, he automatically replied, absent-minded.

- Are-you-finished ? she repeated louder.

Onii-san jumped up, startled out of his dream.

- Y-yes ! Sorry ! It's all set !

His eyes were unable to maintain eye contact with the mischievous look of Ai-chan and he downed them, quickly peeking again for a short second at the two enormous mountains a few centimeters from his head. That's when he saw it. The button of her apron, the one at where her chest was the biggest, was just a few moments away from popping. Her gigantic breasts were only held by a small thread of tissue holding the button, God only knew how. This resulted in a large gap of around 3 centimeters where one could easily peek inside her apron to look at her white-laced bra. All the bouncing and jiggling of such tremendous masses of flesh proved to be way too powerful for the button of the apron that was about to break.

- W-wait, it's not set! Not set at all! It's in danger! nervously replied Onii-san.

Ai-chan looked at him, tilting her head on the side, visibly confused.

- There's a huge issue! said Onii-san emphasizing on the word "huge" to indicate her chest.

Yet, Ai-chan did not seem to understand, her eyebrows frowned in a cute innocent and clueless manner. She leaned towards him, further putting pressure on the button that could not hold for very long. Onii-san whispered to his ear :

- You… hum… You're about to make my good luck charm for this week, said Onii-san with his voice trembling.

Ai-chan immediately passed a hand down to her button only to feel the great gap formed and the lonely string holding everything in place. Her face reddened faster than a traffic light as she put her hand in front of the gap, forbidding any more peeking. After a slight nod of thankfulness, she rushed to her female manager, this time holding her huge chest tight to avoid any bouncing that would prove to be fatal to other buttons. Onii-san sighed in relief, fearing that his good luck charm for the week was to be taken by someone else. In this distance, he overheard the discussion with her manager. He could not listen to what Ai-chan was saying but he heard the apologizing tone and shame in her voice. Her female co-worker's disbelief was a bit more louder for him to faintly listen what she was saying :

- Eeeeeh! Again!? What did you do this time?

- N-nothing particular, replied Ai-chan, apologizing.

- Can't you find a way to fix it?

- Y-yes if I can go the changing room

- Nevermind. You can stop your shift now, you're lucky we're closing, replied the manager.

Ai-chan disappeared in the staff area. Onii-san could not help but to chuckle a bit, seeing her weapons turning against her. She was indeed way too powerful even for a specifically designed cloth. Life was surely difficult for a J-cup angel.


Inside the changing room, some of the other waitresses were also changing.

- Looks like you outdone yourself again ! giggled one of her colleagues.

Ai-chan giggled politely back before undressing her shirt. Finally free of it, she adjusted her tight bra and looked at the damage on her waitress uniform. She sighed heavily : more and more buttons have been really popping off recently. She could sew it back for sure but her whole week was so packed with activities that she didn't know when she'll be able to do it. Her eyes lit up and a large smile appeared on her face as she got an idea.


- Dear guests, it is 6h55, we are going to close the waitress bakery, said the manager to the rest of the room. Can you please pay what you ordered and we hope you enjoyed our meals and service. We look forward to seeing you again.

Onii-san left the table, quite a bit sad not to have seen Ai-chan again since her incident. She was still probably struggling with her apron for the last 15 minutes. As he was waiting in the queue to pay, he overheard two waitresses talking silently to each other :

- Yeah, she popped a button apparently

- Again!? She really is incredible!

- Don't you think she was a bit off today?

- She's usually energetic but still somewhat composed. Do you think something happened to her?

- Yeah, definitely! She looked even cuter than usual.

- You're right about that!

Onii-san was driven out of their conversation as the cashier asked him to pay and he left the restaurant, his mind troubled. Five minutes later, he was walking outside, in the late afternoon streets. That's when he heard his angel screaming in the distance :

- Onii-saaaaan!

He turned around and saw Ai-chan running towards him. She was still wearing her waitress apron and simply put a blazer above it. On her right hand she was carefully holding a bakery bag but Onii-san eyes were mainly focused on her chest, as usual. He always saw it bounce when she walked but her run made it to a whole new level. Each step made her whole monstrous chest lift in the air, defying the laws of physics. At the peak of the height allowed by her apron, her breasts almost completely reached the height of her shoulders. Then, the tremendous weight of her mountains made them fall with all their might. Finally, the momentum and elasticity of her young flesh made them bounce back again in the air. Everyone in the street looked at this miracle from heaven. The boys of course did not miss a single image of the bouncing. Single girls looked with envy while the ones with a boyfriend tried to divert attention or looked angrily at them. When she arrived at this level, she stopped, breathing heavily. Onii-san noticed that she temporarily replaced her missing button with a small safety pin but even it won't hold very long with her exhausted breathing.

- Ai-chan? What's wrong?

She passed her arm under her bust, probably to rest a bit after all the heavy bouncing but that made them even more bigger for him.

- You forgot this! she said, exhausted while handing him her bag with her other arm. I told you I would give you some bread to take home!

- A-ah! Sorry! he replied

- Alright, my shift isn't done yet so I'll see you next Monday!

As she turned to go back, Onii-san shouted :

- Oh! Ai-chan!

She looked at him with her big green eyes.

- Thank you for inviting me today. It was refreshing to see you in a different light. And your waitress uniform... You were really cute. But most importantly, when you were working, you were so cool and it inspired me to work even harder! It motivated me to study for my degree!

Ai-chan looked at him in disbelief, her eyes wide open. She rushed at him, squishing her body against his, tilting her head to look at him with pure joy on her face :

- I was cool!?

- Y-yeah ! You were really cool! said Onii-san, trying not to think about Ai-chan's body pressed against his torso. She backed off, quite shocked and pleased by his compliment.

- That's a first... She said to herself. Anyway, I'm gonna go back to work now!

- Yup, good luck!

- Yes, thank you! Good luck with your studies.

She was about to leave when she said :

- Oh and..

She turned over and stopped half-way, offering a side view of her body. There, she filled her lungs with air and put her shoulders back, sticking out her chest. Her breasts grew more and more, gaining even more volume. Gaps were forming in between her buttons while her safety pin greatly deformed the sides of her uniform in an attempt to maintain her chest. Her volume was beyond any comprehension, even more bigger than what Onii-san would have thought. She used the full potential of her apron to give even more visual effects on her chest while the creases and the safety pin emphasized her bust circumference. She was showing the full power of her J-cup massive bosom. Seeing it from the side was also different as he could definitely see the beautiful unbalance of her chest, as massive it was. Again, she showed the same proudful and teasing smirk, greatly enjoying the look of shock on his friend's face. Her eyes sparkled with mischief and playfulness. There, she gently tapped on the safety pin that was almost on the point of tearing apart the sides of her uniform :

- Your lucky charm has been freshly made~

Onii-san gulped down. Ai-chan's smirk, on the other hand, grew even wider. Still tapping on her safety pin, flirting with disaster, she added :

- I told you it was not difficult for me to create new good luck charms ~

She finished with a playful wink that completely melted Onii-san. She emptied her lungs, decreasing the unbelievable pressure she was putting on her uniform and safety pin but her chest remained obviously enormous. She waved at him with a big joyful smile, leaving him alone, speechless, his mouth gaping. He noticed that this time she left holding her chest in position which meant she let it bounce freely when she ran towards him earlier for him to see. He opened the bag to see what was inside. There, he saw two big round loaves of bread and tucked in-between them there was her uniform's button she just recently popped. The metaphor was not really hard to understand. Onii-san smiled : Ai-chan was definitely a master in terms of playing with him.


- Thank you ! I've heard you may have any other questions or concerns regarding the current uniform ?

The question was asked by a young woman to Ai-chan at the back of the bakery. The manager of the bakery had managed to arrange a meeting with Ai-chan and this lady to discuss the uniforms as she requested. This young woman was in her mid-twenties with deep-blue eyes and a mole on her right eye. She had long brown hair with a nice hair clip on her side. Her chest was also incredibly large, probably reaching a I or J-cup, tightly squeezed in her office outfit. It was without saying that she was incredibly beautiful as well. It was the first time that Ai-chan was meeting her but she was told by her manager to call her by her favorite nickname : Kouhai-chan, meaning "junior".

- I-it's very cute actually ! I love it ! answered Ai-chan.

- Fufu… I must say, it looks great on you ! The designers and manufacturer will be overjoyed once they find out someone like you is wearing their uniform ! giggled Kouhai-chan.

She quickly typed on her computer before coming back to Ai-chan with a sorry expression and a comforting smile.

- But I'm afraid… That any suggestions regarding the size variations are…unlikely to go through…

- Just like I thought, sighed Ai-chan with the same sorry expression

- We…We don't have a large size actually

- If only I was slightly taller…, replied Ai-chan, slightly annoyed

- I'll still put it on the proposal though, of course. Maybe if the manufacturers know that someone like you is wearing one of their uniforms… My advice would be to keep a few spare buttons.

- I wish I had a build like yours…

Ai-chan gasped. Her words had come out of her mouth without thinking and she started to blush immediately

- Ah ! I'm sorry ! It was rude of me to suddenly talk about your figure !

- Ahaha, it's alright. It's hard to talk about… this with other people.

They both laughed like kindred spirits. Ai-chan, just like Kouhai-chan, never managed to meet another person with breasts as big as them. Talking about her fitting problems was always seen as arrogant with her other classmates or co-workers. Each time Ai-chan mentioned this topic with her schoolmates, they would just think she was trying to make them angry.

- Your shirt fits you so well, said Ai-chan. You don't get weird creases in it like I do, she said, extending her arms to showcase the large creases all across her chest as the safety pin made its best to not tear apart the fabric. Is it custom-made ?

- Nope, not at all, said Kouhai-chan, extending her arms too to stick out her huge chest as well. It's made specifically for people like m-... like us ! By using a specific draping process, this brand makes clothing that fits m-...our body types !

- Amazing, I want one too !

- I'll show you one on my phone.

As Kouhai-chan was looking through her phone, she started to doubt that even this brand would fit this young girl. Even though Kouhai-chan had herself a sizable J-cup bosom, this young teenager was already bigger than her and surely still growing. Even her, at her age, was not as well-endowed than her. She always had the largest chest in every class, association or working company but this young teenager was already topping her this young.

- They don't make a lot of them so… it's slightly expensive actually!

- I do have a part-time job… so I'll make it work somehow ! confidently said Ai-chan.

- Also, there's a hidden button inside to make sure any gap isn't visible. And it's well-made so the buttons won't fly off or anything.

Kouhai-chan lowered her eyes down on Ai-chan's massive chest.

- Although… I would advise that… Given the price… that you would wait to finish your…growth…

- Ooh that's… not great. The buttons have to fly off. plainly said Ai-chan

Kouhai-chan slow-blinked in disbelief. She looked at the young teenager with confusion.

- I'm sorry, what ?

Ai-chan faintly smiled and put her hands on her chest, just above the gap held by her safety pin. Closing her eyes, she thought about the glances of Onii-san on her, his joy and excitement, how good she was feeling to tease him and being looked at by him.

- There's a certain person out there, said Ai-chan with a low passionate voice, who wouldn't be able to survive the week if my buttons don't pop off…

- Eh ? said Kouhai-chan, raising an eyebrow.

Someone knocked at the door and entered. It was a young man in his mid-twenties as well with hair covering his forehead and his eyes.

- Ah Senpai ! said Kouhai-chan, I've just finished interviewing the girls.

Ai-chan stood up and thanked both of them and passed in front of Senpai. Kouhai-chan noticed his dazzled look as the young teenager passed in front of him. He was completely mesmerized by her beauty before his eyes downed on her chest and more especially her safety pin.

- What's wrong, Senpai ? asked Kouhai-chan.

- No-nothing… Let's go back to the office.

Kouhai-chan looked at the young girl who was going away in the corridor. Both of them could see her large bosom sway. The businesswoman looked down at her shirt and her large bosom as well. She wondered what Senpai would think if she would wear the same waitress uniform or if she would let her buttons pop off.

- Oh by the way, miss ? shouted Senpai to Ai-chan.

Ai-chan turned on its side, showing her amazing silhouette and large curves of her body.

- You can send your uniform with your button for sewing before your next shift!

- Oh… Actually..., said Ai-chan with sparkles in her eyes, I may have unfortunately lost that button…

Ai-chan looked at Kouhai-chan with a devious and mischievous smile and the businesswoman smiled back at her. "So that was how to play with men", she thought with a smile.
