Ai-chan moaned softly in discomfort. She was in her classroom during one break in between two courses. Her classmates were all busy talking with each other, going to the restroom, eating a snack or simply getting a quick nap before the next course would start. Ai-chan however was a particular girl as she was the class delegate. Her job mainly consisted in acting as a bridge in between the staff and her classmates. There were some exciting tasks and they were boring ones too. Namely, the one she was trying to do was definitely falling in the range of the boring ones, by far. After each course, she had to clean the chalkboard much to her dismay. The reason was fairly simple as she was remarkably short even for girls of her age. As a matter of fact, her 150cm of height definitely placed her amongst the shortest girls of her age.

And there she was again, trying to clean the highest areas of the chalkboard. She was on tiptoes, desperately trying to win a few centimeters her extended arm couldn't reach. However, this position was greatly impeding her not-so-great balance. This meant that she had no other choice but to bend forward, leaning her enormous chest on the chalkboard. While helping her to balance herself initially, this position led to other disadvantages. Because her bosom wasn't just big or huge, it was massive. Her J-cup breasts were just simply way too big for her to rest on them in a proper way. Their sheer masses, let alone their softness, were actively working against her, pushing her away from the chalkboard. Being on tiptoes in this situation was not helping. Therefore, she had no other choice but to crush her gifted body even more on the chalkboard and her oversized assets slyly retaliated by pushing her even harder. To top it all, having her bust crushed on something this hard was also impairing her breathing as well as being painful. Hence, she couldn't help but softly moan desperately to herself about her makeshift solution her extraordinary body was putting her through.

Suddenly, the busty teenager felt a presence behind her that made her jump in surprise. A feminine hand landed on Ai-chan's left wide hip while another one took the brush out of her hand.

- Here, let me do that for you, class prez'. said a girl behind Ai-chan.

She turned around and immediately recognised her best female friend.

- Thanks, you saved me ! said Ai-chan with a large thankful and joyful smile.

Ai-chan watched over her best friend while she was cleaning up the chalkboard with ease. This girl had messy short hair as well as fairly large breasts, even though there were no comparison possible between the two of them. Overall, she had a very tomboy look and attitude. She was quite a tall girl, quite the contrary to Ai-chan, topping her by more than 15 centimeters. Her impressive height for a girl lead her to volleyball, making her known as "Volleybu-chan" at school for those who didn't know her actual name.

Volleybu-chan must have felt her gaze on her as she turned around to face her friend :

- What ? she asked.

- I just wish I was taller.

Ai-chan answered almost absentmindedly. She always had been self-conscious about her quite short height and seeing Onii-san and Volleybu-chan just a few hours away from each other was hitting her about how short she was.

- Awww, I like short and cute girls like you, prez'. Please stay like that forever ! jokingly replied Volleybu-chan.

She gently patted the top of Ai-chan's head.

- No way ! replied Ai-chan. You have to be cool nowadays ! Being tall is cool !

Volleybu-chan chuckled seeing Ai-chan acting so cute. "Sure, being tall is cool for a woman but I can think of two other freaking huge arguments you have, girl" she thought. Speaking of which, she looked down towards her friend's massive bosom. As winter was already here, Ai-chan was wearing a cute sweater on top of her school uniform's shirt. Yet, that didn't help reduce the incredible size of her bust, making it look even rounder and softer by any means. Volleybu-chan immediately noticed the huge marks of white chalk all around her bosom.

- Ah ! Stop moving for a second. You have some chalk dust on you !

Volleybu-chan rubbed swiftly her hand on Ai-chan's J-cup mountains making them jiggle with each stroke. Not only were they huge, but they were also showing their softness and great elasticity. But as the two girls were innocently looking at the masses getting cleaned of chalk dust, something happened. In less than a second after Volleybu-chan's finger had touched Ai-chan's delicate flesh, a great thrill passed through every single boy in the classroom. They all stopped talking all of a sudden, making the room way quieter than before. Both Ai-chan and Volleybu-chan looked at each other with wide eyes before the latter started chuckling.

- Well, well, well, what's wrong ? Calm down, guys, sneered Volleybu-chan, still wiping out the dust off the Ai-Chan's ample bosom.

The busty teenager remained motionless, her big green eyes wide open in shock.

- Is there something wrong with a girl wiping some dust from another girl's clothes ? mischievously asked Volleybu-chan.

The tall girl was now purposefully rubbing harder on Ai-chan's huge mountains with each stroke now, to get rid of the remaining chalk. The jiggling of Ai-chan's kept intensifying with each stroke, showing how large it was. The busty teenager's heart sank as she finally understood that everyone was looking at her oversized chest.

- Well, it's not like I don't understand how you feel... but...

Volleybu-chan placed herself behind her busty friend who was now facing the whole classroom and especially the boys. Ai-chan felt her cheeks turning red in embarrassment. But before she could even utter a word she felt Volleybu-chan's hands swiftly passing her hands under her armpits. Volleybu-chan's greedy fingers grabbed as much of Ai'chan's mountains as they could and lifted them teasingly. Her delicious flesh overflowed abundantly in between her friend's hands, obviously way too small to grab them completely. To top it all, the effort shown by Volleybu-chan's hands just to lift her wonderfully massive mountains greatly suggested just how heavy they were. Ai-chan squealed of surprise and embarrassment, her arms remaining useless as her friend lifted her assets, exposing how incredibly large she was to the rest of the boys.

- How's this? Jealous, guys? she shouted to the male audience in a mocking giggle.

No boys actually replied to her but the same thrill as before went through them, causing a great disturbance in the classroom. The silence was so loud that even the girls had started to look in their direction. A few isolated boys however could not help but to let go of a frustrated sigh, strongly indicating their craving envy to touch them as well. The boys were mainly split into two categories. The first ones, probably the more confident ones, kept their gaze on Ai-chan's bosom as Volleybu-chan lifted them. They observed with attention every part of her breasts' physical reaction being lifted. The other category quickly turned away, some of embarrassment, others of pure jealousy. But even them had to ultimately give up to their instincts and risk a quick glance at the busty girl. The stronger ones only managed to look away for mere seconds.

- Why do you always do this? squealed Ai-Chan with a high-pitched uncomfortable voice as her face was as red as a tomato.

Volleybu-chan giggled.

- You perfectly know why, they are incredible.

Volleybu-chan started to fondle her friend's enormous gifts. Each squeeze made her bountiful flesh overflow a bit more in between her fingers, much to the boys' delight.

- Ooh, I think they even got bigger than before, didn't they ?

She squeezed her friend's bigger-than-her-head breasts a bit harder, groping as much flesh as she could at each grab while Ai-chan barely managed to say "stop" with a small voice. The lack of denial from her part to Volleybu-chan's question only created more arousal in the boys' area. She had grown again.

- My god, they're so massive. Is that why you can't even button your jacket anymore?

- Le-let me go! squealed Ai-chan.

She didn't want anyone to know that she wasn't able to button her jacket since she had grown to her whopping J-cup. But to be fair, it's been a few weeks already that she wasn't able to, making her the only girl in the whole school to suffer from this "handicap". Most of the people in school probably already knew about that already. Volleybu-chan, on the other hand, kept on massaging and caressing her breasts, touching every centimeters of her friends tremendously huge monsters.

- Yeah... You definitely grew again! giggled Volleybu-chan with praise. Look !

She grabbed firmly Ai-chan's bosom and squeezed them, again showing how her bust overflowed her hands. Then, Volleybu-chan gently shook her hands, showing to everyone how much Ai-chan's flesh was jiggling in between her fingers. They simply looked enormous.

- They don't even fit in my hands ! Volleybu-chan sighed happily. It's not like they could before, though... she giggled, but still... You're really gonna hit the 3-digits soon !

Some boys sighed in disbelief. 3-digits... How would that even be possible ? Wasn't that only reserved for gravure idols or unreacheable girls you see in magazines ? How could a high-school sudent like them be this huge ! Volleybu-chan let go of Ai-chan's massive bosom that bounced back heavily before she grabbed it again this time much harder than before, underlined by Ai-chan's soft moan.

- I understand why you're captivating all the men around you...

- I-.. I'm not ca-captivating anyone ! replied Ai-chan a bit more louder, just like she was trying to convince anyone here, even herself.

She was in pure denial as it was clear that most men couldn't even look away from her, enjoying in great detail and envy her breasts getting squeezed. Without even bothering to answer her denial, Volleybu-chan squeezed her friend's imposing breasts against one other. Ai-chan's shirt was immediately gulped down inside her deep cleavage, marking the clear separation of her breasts to everyone. Very slowly, Volleybu-chan rubbed Ai-chan's breasts against each other. The crushing force of her two J-cup mountains was gulping more and more of her shirt inside her voracious cleavage, so much that her collar kept going lower and lower, risking revealing her canyon to everyone. Volleybu-chan leaned her head on Ai-chan's shoulder and whisper only for her to hear :

- Look at them.

Ai-chan, her face as red as ever, gathered enough courage to face her admirers. All of them were also red, visibly aroused seeing Ai-chan's getting rubbed against each other. Most of them had sat down, hiding their lower body part but as soon as the two girl's gaze met another man, he would turn even redder than what was humanly possible and look away. The contrast between the two girls was incredible. Ai-chan's big and beautiful green eyes looked at them with an interrogating look, clearly not understanding what was happening. On the other hand, Volleybu-chan looked at every single one of them with a large mocking grin on her mouth, visibly enjoying teasing the boys. She made sure to keep rubbing Ai-chan's breasts very slowly against each other, trying to hold her escaping flesh as much as she could. It was clear that she knew every boy's dream and Ai-chan wasn't. Yet, even her could not help but notice how mesmerized they looked. Volleybu-chan whispered once again to her ear :

- Every...single...one of them.

Ai-chan's face had reached a bright red color now and Volleybu-chan turned her around to hide her from the male's gazes. Around 3 or 4 boys hurriedly got out of the classroom, walking in a funny way towards the restrooms. Two other girls were also walking towards their boyfriend with stormy eyes, demanding them to have a discussion outside.

Volleybu-chan stopped her groping, making Ai-chan sigh of relief as her bosom bounced back in its natural position. She teasefully pulled out her shirt out of her busty friend's cleavage. Instead of groping her, she placed her forearm under her chest, allowing her friend to rest her massive mountains of flesh on it. Therefore, Volleybu-chan could still greatly appreciate the incredible mass and weight Ai-chan was displaying.

- Say, how many seniors have asked for your contact since you started high school ? And how many of them have confessed to you?

Ai-chan remained silent, a bit embarrassed. She actually couldn't remember how many boys went to ask her out. Probably more than 20, if she had to guess. Some of them were actually in that room, giving Volleybu-chan the enviest of look. She remembered their gazes on her tight uniform on her first day. Back then, she was still able to button it up, even if it was barely. Satisfied of her silence, Volleybu-chan continued :

- I can't even remember how many of my seniors from the volleyball team have already asked me to introduce you to them.

Ai-Chan sighed uncomfortably :

- I- I said I was sorry about that...

- Just tell me how many times you've been hit on while walking around town. And what about those suspicious people trying to scout you all the time?

Ai-chan nodded, embarrassed. Volleybu-chan was speaking facts for sure but her ego was torn apart between boastful and embarrassment.

- Oh it's fine, it's fine, continued her friend. I'm just worried about you. In school I can protect you a bit but prez', you come to school by train every day, right?

Ai-chan swallowed with difficulty and remained silent, fearful of what was going to come. From above Ai-chan's shoulder, Volleybu-chan saw the weird irregularities and bumps on her friend's breasts. It was clear that Ai-chan's enormous mountains were overflowing from her bra's cups after Volleybu-chan's groping. As an apology, she lift her arms up, letting the giant bosom freely bounce in its normal position and pinched the bra's straps before lifting them up. The enormous mounts fit back inside with difficulty inside their cups, making Ai-chan sigh of relief again. Volleybu-chan clawed her fingers on her friend's perfectly flat belly, pressing her body against her back.

- Are there any weird men pressing their bodies against you?

Ai-chan's heart sank in her chest and started pounding hard. At that moment, she was a bit glad to have such an enormous bosom that would make it hard for Volleybu-chan to feel the racing pace of her heart. Her mind immediately thought about Onii-san and her innocent plays every Monday morning. What would Volleybu-chan and the others think of these plays she was giving to an older man? After all, this Monday morning too, she purposefully pressed her massive bosom on his body to cheer him up. This Monday morning too, she gave him another button that popped from her shirt on Thursday evening.

Gathering all the determination she could, she replied as convincingly as possible :

- Th-There's no one like that at all!

- Hmm, are you sure? Your train is always packed, right? Aren't they pressing their bodies on purpose?

Onii-san's belly came back at her again. How many times had she played with him ? How many times did she lean on him ?He was so kind to her and it was definitely her that was teasing him. If people would think the other way around, it could end badly for Onii-san as he was much older than her.

- Not all men are like that, you know, she simply replied with a trembling voice.

- Hmm I'm still worried. Don't you trust them a bit too much?

Volleybu-chan come closer to her ear :

- Those "gentlemen" who pretend they don't have any interest in boobs are exactly the ones who let their repressed urges go the moment they get the chance, Volleybu-chan said while softly squeezing her friend's breasts with her forearms.

Ai-chan was left speechless. Was she right? It's been several weeks now that she knew Onii-san and she could remember every expression he had when both their bodies met. She could remember the pure joy in his eyes each time she was giving him a button from her shirt. But was she wrong in thinking he had any interest in her besides her body?

- So prez'...

Volleybu-chan unclawed her hands and lifted once again Ai-chan's massive breasts, gently weighting their enormous weight. She whispered :

- You should just ignore all these men and pent-up desires and engage in the pure love between two women...

Even before Ai-Chan could understand the true meaning of her sentence, she heard a loud "bam" and felt Volleybu-chan leaving her chest which bounced back again heavily. The other girls had slapped her friend on top of her head.

- You're the one with the repressing urges!

- Prez', are you all right?

- What a perverted girl!

Volleybu-chan complained :

- No you don't understand! You'll do once you touch them! They're amazing!

- If you want something to touch, then just go touch your own ! scolded a girl, You've got a nice pair yourself ! she added, her voice betraying her jealousy.

Volleybu-chan thought about it. She fondled herself, weighing her own bosom but couldn't help but feel ridiculous after groping Ai-chan's mountains. Yet, she must admit it, they were quite big as well. Quite recently, she had managed to reach an F-cup which put her as the second bustiest girl in their class.

- Yeah, they've been growing pretty quickly recently.

An idea flashed inside her eyes.

- Girls ! Wait ! Think about it... it must be a sign !

Ai-chan and the other girls looked at her with interrogating eyes. The tall girl grabbed her large breasts and said with devious mischief :

- Her boobs are a blessing ! That's how Igot so big !

Ai-chan chuckled a little about the joke but her smile vanished as she saw the other girl slowly turning their head on her with a serious expression.

- Girls ? asked Ai-chan with a scared smile.

A wave of jealousy and envy pulsate through the air as the girls considered the possibility that Ai-chan was indeed a goddess. After all, the difference between them and her was vertiginous. In a few seconds, Volleybu-chan grabbed Ai-chan while the other girls approached her hands to the massive chest, trying desperately to provoke chance.

- You betrayed me ! screamed Ai-chan as her envious classmates groped her.
