For her to join them for a good time

A group of boys were on their way to a bar just as school had ended. The boys in question were the "masterminds" behind the breast-note. As they were sauntering, throwing rocks at random signs and objects one of the boys called out to the group:
"Yo, isn't that the prez?"
"Yea, I'll recognize those tits anywhere, even from behind!" another one of them exclaimed.
"We should ask her to join us, think she'd say yes?".
"No way in hell bro, but you can try!". A third boy snickered.
"Challenge accepted"

On the other end, Aiko was minding her own business, excited to get herself some gachas on her way home. Just as she was getting around the corner, off the main street she was approached by someone. A boy from class, who she remembered had been at the table when she inspected the paper earlier.
"Wanna join us for a good time?" He asked her, quite forward.
"We're headed to that bar just over there". He pointed to a tired, worn down corner shop with a saggy, obviously loose sign. "Drunken stud".
"In your dreams". Aiko was quick to shut his proposal down, never had she been interested in drinking, or any sort of social gathering based around ****. Especially with guys like him and his friends whom she spotted a tad further down the street.
"Also.." The young president was about to add something. She was about to protest the boys intention of going to a bar whilst still dressed in their uniforms. They ought to know that the school didn't take lightly on it's image, wearing the uniform in such places was strictly forbidden. Alas, her words got stuck in her throat, which only preceded the purple mist appearing. As per usual, nobody noticed the purple smog and it quickly faded into nothingness, leaving a slightly altered Aiko in the aftermath.
The girl couldn't for the life of her remember what she'd gotten so worked up about. She looked back at the boy, thinking back to his proposal. Sure, what he proposed hadn't appealed to her specifically, as she didn't enjoy that sort of activity. She did however see nothing wrong with the concept of going to a bar after school, even whilst wearing the school uniform. Her uniform practically screamed indecent, so what does it matter that anyone would wanna hit up a bar in theirs?

Aiko wasn't too keen on hanging around too much longer. She told the boy goodbye and to have a good time and went on her merry way. Completely forgetting to get her gachas on her way home.

Nothing notable happened for the remainder of the day. She came home, ate, studied and went to bed.
The following morning Aiko found the time to check her Instagram. She rarely, if ever, made a post. When she did make a post it was usually something related to public morals, or a cute gacha she'd gotten. She did find it important to stay updated on the current trends and seeing what her fellow students were up to. As she mindlessly scrolled through post after post of catpics and other mundane stuff she came across a risqué selfie that had been uploaded by a girl that went the same year as her, but a different class. The girl in question was wearing her school uniform, but she'd lifted what seemed to be a G-string above the hemline of her skirt. Showcasing a thin, pink piece of fabric. The caption read: "Trying on my latest haul, think my BF will like them? Oh, I've got a matching piece upstairs.. ;)"
"What indecent behavior, doesn't she know that those images are stuck online forever?!" Aiko murmured to herself.
No way was she gonna let that girl do this to herself, not to mention it was inappropriate to wear such underwear to school. The president swiftly typed out a comment, telling the girl exactly what she thought about her attire.
"That's so wrong! No aspiring student should wear such undergarments, especially at school! Have you no shame? Even going as far as to expose yourself in such a manner on social media! Shame. I'll be seeing you at school, hope you're prepared to meet with the headmistress, too!"
Aiko was far from experienced with the world of social media. Most of her messages and comments read like a novel, an old fashioned drama.
Her finger clicked enter, and her comment had been submitted. In the exact same moment the familiar purple mist had creeped its way up along Aiko's body, shrouding her and her phone in thick purple. Once it faded both Aiko and her comment looked a bit different..
