Something else entirely

"That's so cute! You should totally wear those at school tomorrow! Where'd you get them? I've got to get me a pair in purple! Great pose, so hot! Lets meet at school and talk!"

Aiko loved wearing G-strings. She frequently uploaded similar images, if not a tad more daring. Finally she'd found someone who shared her interest, no way was she letting this chance pass her by. She absolutely adored the texture of the fabric too, she NEEDED to know where to get some for herself. Thinking about the different typed of underwear she could post next Aiko inspected her current outfit.
"Might as well post something of my own, I guess".
She put the phone on her desk and balanced it up against a book to get the perfect angle for her shot.

She posed and waited. And waited. And waited. How long of a timer had she put? She looked at her phone quizzically, wondering if she'd remember to prime it. As she looked dumbfounded over at her desk, the flash went off and the picture was taken. Normally Aiko would've inspected the picture, maybe taken a new one. Time was however running out and she had to make it to school on time. She may have a crippling addiction to social media, but she still knew to balance it with school, though it'd be a lie to claim that her grades didn't get affected. She could've been a straight A student, but her dedication to social media prevented that. Leaving her with almost all C's, with the occasional B sprinkled in whenever she could rely on group projects. All the nerds in her class would throw themselves at her whenever there was a group effort, doing basically everything whilst Aiko sat there on her phone, scrolling through her Instagram. She was practically a goddess on social media at this point. Her unique style pared with her curvy body made for a killer combo. Her followers were mainly horny men, but that didn't bother her the slightest, to be frank, she quite enjoyed the attention it brought her. Reading through the waterfall of horny simps commenting on her posts was her favorite thing in the world, it was also the prime culprit of why her grades were far from optimal.

Aiko had to run to school, again. Her ability to manage time had severely tanked since starting with Instagram. She'd dedicate thirty minutes to it in the morning before school, which should be an ample amount of time for her to walk at a comfortable pace. Those thirty minutes however almost always turned into a forty to fifty minute brain-rotting experience. Her ability to concentrate had diminished over the years as a result of countless hours of idle scrolling. Fortunately for Aiko, she'd never really caught an interest in Tik Tok. It would mean the end to her academic prospects if she ever caught that specific fever, which was why she actively avoided it. Too bad she'd fallen into the trap of Instagram so soon.

Arriving at school, Aiko headed straight for the gymnasium. Gym was the first class of the day, and prime time for Aiko to catch a sweat. It really made her skin glisten before hitting the showers, perfect for hot pictures that she could upload. Her routine of taking steamy pictures in the girls lockers made her fairly unpopular with some of her female classmates. It didn't really bother her much though, her popularity with the boys had skyrocketed since she started, so from a purely utilitarian perspective it was worth it.

Gym class began and it was that time of year where the students stamina was being tested. The only item on the program was a 5km run around the track that wrapped around the school football field. Aiko was a fairly decent runner, having good genes and a adequate exercise regime. Unfortunately not everyone was as blessed as Aiko when it came to athletics. The old Aiko may have been kind to these students, giving them cheerful encouragement, trying to help them become the best version on themselves.

This new, slightly corrupted Aiko knew of no such values. This iteration of Aiko lacked a sense of compassion. She was also quite vain. Probably a side effect to constantly being on social media and being put on a pedestal for the past few years.
This pared with her disdain for students who failed to put enough effort into their looks created a situation where Aiko felt a sudden need to berate a slightly chubby classmate. Hitomi, who wasn't as blessed genetically as Aiko was a tad overweight. The chubby girl really struggled with the yearly 5km and was quite self aware of this fact, Aiko knew that all too well. The president had almost made a routine of stating that fact over and over whenever running became a topic.

Aiko approached Hitomi and saw how scared the girl was. She knew what was coming, and was not looking forwards to it.
The president walked up and around the pudgy girl and brought her arms around her in a dramatic fashion, grabbing hold of her little "love handles".
As she fondled her almost non existent belly-rolls she leaned in close to her ear and pursed her lips. What she was about to say was something along the lines of:
"You should eat less and run more, beauty isn't optional in this day and age, you should smile more, you should take better care of yourself. No one likes a chubster. Your thighs rub when you walk, it's disgusting.."

Those words never made it past her lips though, instead she exhaled a purple smoke into Hitomi's ear. The smoke continued past her ear and covered the two girls before disappearing. Once it was clear neither of them seemed to have any recollection of what had happened. Two things would've been immediately obvious to any onlooker though, granted that they weren't also affected by the smoke.
