Smack!
Inside the doujinshi hall, accompanied by the crisp sound of a playing card being slapped down, Chika Fujiwara, the 'Cancer of the Earth', raised both hands high and cheered.
They didn't really have much interest in the anime subculture, but seeing Rin Ito and the others going, they tagged along to join the fun... They didn't expect to actually find something Chika enjoyed playing here.
Chika Fujiwara was sitting at a trial table for a Kantai Collection doujinshi board game circle, playing a board game with someone using a deck she had just bought. Chika and Moeha stood behind her, cheering her on.
"I won~ Yay~ Hehehe~ Which card should I take?"
What was originally just a normal game had, at Chika's proposal, turned into a 'Shadow Game' where the winner could take one card from the loser's deck.
The boy sitting across from her, who looked only twelve or thirteen, had his eyes squeezed tightly shut, muttering to himself as if praying that the pink devil before him wouldn't draw a rare card.
"Hehehe..." Chika extended her index finger and swept it back and forth across the card backs in front of the boy. Although she acted like an airhead, she was secretly observing his facial expressions.
"!!!"
The exact moment the boy's heart clenched, Chika's finger stopped.
"This one then, I'll be taking it~" Chika picked up the card with a beaming smile.
"Ugh!!! My Shimakaze!!!" The boy clutched his head, his face full of regret.
I'm so stupid, truly.
I thought this airheaded big sister was just an easy-to-bully newbie, so I agreed. I didn't expect... a devil! She's an absolute devil!
"Dammit (〃＞皿＜)!!!!"
"Hehehe~~ Want to play another round? Let's bet two cards this time!!! Ouch!!! That hurts!" The triumphant Chika instantly covered her head and spun around, only to see Rin Ito standing behind her.
"This is... Shimakaze, right? Here, you can have it back." Rin Ito handed the Shimakaze card back to the boy, then knocked on Chika's head again.
"Mmh!! Thank you, Big Brother!!!"
The boy accepted it with immense gratitude and hurried away. Rin Ito then pulled Chika away from the trial table.
"Ugh!!!" Chika puffed her cheeks out and glared at Rin Ito, while Moeha and Kei held back their laughter nearby. "That was my loot! And I didn't lie to him, I really am a beginner."
"I didn't think you'd actually bully a kid... In a doujinshi, you'd definitely get 'run over by a massive truck' for acting like that. I know a much more fun game, want to play?"
"What game!?"
Before Chika could even speak, Moeha was already practically bouncing with excitement. Rin Ito waved his hand dismissively.
"Flat-chested girls can't play."
Moeha: "..."
Kei: "..."
For a moment, both Moeha and Kei fell silent. Even though they couldn't compare to Chika, they weren't exactly small either. Plus, what the hell kind of game can only be played by busty girls!?
"Pfft~ What a pity. Looks like Moeha and Kei-chan will have to wait a few more years before they can play." Chika proudly puffed out her massive, faintly milk-scented breasts. "What game is it?"
Rin Ito mischievously waved Moeha and Kei away, telling them to stand further back, before leaning close to Chika's ear.
"A game to help Sajuna adapt to massive breasts... Sajuna is almost a high school senior now, but her body is still petite and completely flat. She actually feels a deep sense of inferiority regarding her figure, while her younger sister..."
Chika put on a serious face. "Bigger than mine!"
"Exactly! Being around her younger sister every day makes her feel incredibly inferior. But her sister... no matter what, is still her sister."
"Mmh mmh, I get it, I totally get it." Chika crossed her arms and nodded repeatedly; she resonated deeply with this... It wasn't her first time being screwed over by Moeha.
But... who asked Moeha to be her younger sister?
As the older sister, she had no choice but to forgive her.
"Even though you aren't as big as Shinju, you still surpass the vast majority of girls. I want to have her play a game with you to adapt to massive breasts. Once she clears your level, she'll definitely be able to handle Shinju's massive breasts."
"For you, it's a game, but for Sajuna, whom you'll be helping, it's pure salvation."
"No problem! Leave it to me!"
...
After finding and convincing Chika, the game discs also arrived. Rin Ito hurried outside to move the discs to the booth. However, he only brought in two hundred copies; the remaining three hundred were left in the car as a reserve.
Just Chika alone wasn't enough. Besides Chika, Rin Ito also asked Karen. During the holidays, Karen had much more free time at her disposal, and she said she was available anytime.
Chika and Karen—that made two people. To complete the plan of helping Sajuna adapt to massive breasts, he needed at least two more busty girls.
Shinju was ruled out first. Although she had the most massive breasts, her status as the younger sister made many things awkward. Aside from Shinju, it was best to find girls who were relatively familiar with Sajuna, preferably the type whose bodies were incredibly sensitive.
Right... Orie should be at the Pleasure Heaven magazine booth in the corporate hall. When it came to massive breasts, Orie was second only to Shinju.
And if he needed one more... Kaede!
Massive breasts + sensitive.
That absolutely had to be Kaede.
Kaede's breast development surpassed that of her peers, though she was still quite a bit smaller than Shinju and Orie... However, in Sajuna's eyes, whether it was Kaede or Orie, it was all the same.
They were all damn huge tits!
As for sensitivity... Rin Ito figured no one was weaker and more sensitive than Kaede.
Thinking of this, Rin Ito immediately contacted Orie. Although Orie was a bit shy, she had just partied with Sajuna not long ago, so they were essentially 'cross-sword' sisters who had shared hardships together.
Helping a sister adapt to massive breasts was nothing... Plus, Orie had some new lingerie she wanted to wear for Rin Ito.
As for Kaede... given Kaede's personality, if he asked her directly, she would definitely refuse.
Kaede: [Hah!? You're asking me to help Sajuna adapt to massive breasts!?]
Kaede: [Although Sajuna is indeed very cute, I'm your girlfriend, yet you want me to help your side chick adapt to massive breasts?]
Kaede: [No way!]
Just as expected.
But well... When it came to dealing with Kaede, Rin Ito had his ways.
Rin Ito: [You haven't partied with Sajuna yet, right?]
Rin Ito: [As my official girlfriend, shouldn't you go and declare your sovereignty to her?]
Rin Ito: [Plus, your breasts are the most beautiful ones I've ever seen. While Shinju's are definitely massive, they don't have the same aesthetic appeal as yours.]
Rin Ito: [And Karen already agreed to join, you know.]
Kaede: [Hmph....]
Rin Ito perfectly grasped his girlfriend's prideful personality. As long as he gave her 'face' and offered her an easy out, there would be absolutely no problem. Especially with Karen participating, she definitely wouldn't refuse.
Kaede: [When?]
Rin Ito: [After this Comiket is over. It mainly depends on when Karen is free. Even during the holidays, she's quite busy.]
After chatting briefly with Kaede, Rin Ito scrolled through his phone contacts... Since I have busty girls, I need flat-chested girls too, so the game is perfectly balanced and wholesome.
Among the girls Rin Ito was involved with, there were quite a few flat-chested girls similar to Sajuna. It was best to find those with slightly sadistic personalities... Kaguya and Hayasaka would be perfect!
