In the last fifteen years, a new craze had swept through Japan: Oppaidols. Female idols with exceptionally large breasts. This wasn't anything terribly new as there have been well-endowed idols throughout the years. However, Mizuki Tachibana was the first to pioneer anything larger than F-cup breasts.
Since then, idols with both natural and artificially enhanced oppai have taken off. Oppaidol groups even began to form in wake of their popularity. But none were able to truly rise in notoriety the same way past idol groups had. That is until about five years ago when the group RAINB-Oppai took center stage.
A five-girl group, RAINB-Oppai started out uploading videos of themselves to the internet. It wasn't long before their popularity skyrocketed, and they quickly landed a record deal. The members of the group were Rika, the energetic blond and de facto leader; Ayako, the short, timid one with green twintails; Izumi, the tall, chubby girl with messy orange hair; Noriko, the blue-haired nadeshiko; and Benika, the sassy, red-haired gyaru.
The group was currently wrapping up a show at Hokkaido with their number one hit Infinite Rainbow Love.
"YOU'VE BEEN SO WONDERFUL TO US, HOKKAIDO!!" Rika addressed the audience as the song finished. "WE HOPE TO PERFORM FOR YOU SOON!! WE LOVE YOUUUUU!!!!"
With practiced grace, the five women exit the stage and head for the dressing room. Once the door was closed, they all breathed a sigh of relief and began their post-show rituals. Rika pulled out her mobile game and started playing, Ayako buried her nose into the latest issue of Shojo Heart, Izumi opened a bag of sweets, Noriko turned on her electric kettle, and Benika popped open a can of beer.
"Aaah! Nothing like a cold one after a show to take the edge off," Benika said flopping into a chair and undoing the top of her uniform.
"Must you be so crass?" Noriko asked her as she poured her tea. "Perhaps a cup of oolong tea would be better for you? It may clear up that head of yours?"
"Like I would ever drink that swill," she said taking another sip of her beer.
"This is an herbal blend that helps ease the mind and promotes good health," Noriko said matter of factly. "You are putting actual swill into your body."
"Will you two knock it off? I can't focus on the level," Rika said looking up from her game. "Great! Now I have to start over. Can you two just give it a rest? You've been like this for as long as I can remember. Ayako and Izumi get along just fine."
She pointed to the other two members of their group. Ayako had settled in Izumi's lap and leaned back against the tall woman's breasts. The petite woman held the magazine out for both of them to read while Izumi would feed candy to her.
"Us, get along?" Benika said crushing the empty can. "As if. I have nothing common with Miss Stuck-Up. Always with her tea ceremonies and 'just so' attitude."
"I feel the same," Noriko said cleaning her teacup. "Lady Crude here is a walking disaster. Tits hanging out and fussing over the latest fashion fad. Such an improper woman."
"You two are weirdly more in common with each other than you think," Rika said shaking her head.
"AM NOT! TAKE THAT BACK!!" both cried out in unison.
At that moment, the door to the dressing room opened and a man backed into the room. There was a crowd of paparazzi outside that were trying to push their way into the room.
"Everyone! Please calm down!" he shouted over the crowd. "You can get pictures and autographs later!" He slammed the door shut and turned around. "Phew, it's a madhouse out there. Didn't think I'd make it here."
"DAISUKE!!!" all five girls cried out once. They stopped what they were doing and immediately crowded around him.
Daisuke Murasaki was the manager of RAINB-Oppai. A man in his twenties, he was a fairly average guy with purple hair. He had been friends with the group since they were kids and even suggested they start performing together.
"Come here, ladies," he said spreading his arms open. They pressed themselves close to him and Daisuke quickly gave each a kiss on the cheek. "You all performed spectacularly today. Though, there are some places that need improvement."
RAINB-Oppai averted their gazes from Daisuke and mumbled under their breaths.
"Izumi," he said turning to the orange-haired woman. "You were half a step behind during Flower Garden. We'll need to work on that."
"Aawww. I thought I had that one down," she groaned and popped some candy into her mouth.
"Noriko," he turned to the blue-haired woman, "You were a bit fast on the dance number for Dream With Me."
"Tch, and I practiced so much," she said folding her arms.
"HA HA!! Miss Perfect ain't so perfect," Benika teased.
"And you, Benika."
"Eep."
"We've told you not to go off set and freestyle."
"Heh heh, sorry about that. Guess I got carried away," she said sheepishly.
"What about us?" Rika indicated to herself and Ayako. "Do we need to improve?"
"No, you performed perfectly today," he said giving them headpats.
Rika bounced at the praise she was given, and Ayako gave a small smile.
"Now, let's get to the limo so we can get some rest. Everyone ready?" he said grabbing the doorknob.
