The locker area.

Leaving the classroom, her cheeks blushing a hot red, Miki walks down the hallway, as she thinks to herself, cupping her hands to her face, 'No way... I'm skipping class!' Recalling briefly the interaction she had with one of her female classmates, Fumiko, before, she recalled her asking her if she was okay, or whether she'd needed somebody to call her sisters.

She was the eldest of four siblings, after all, so it come in handy to call her siblings to help her state, or so she thought anyways.

Continuing to walk down the hallway, she thought to herself, 'Sorry, Fumiko... This, is not a cold...' Her steps were accompanied by heavy breaths of air, as she could almost feel like an aura of steam form around her. 'My face was red because...'

As Miki looked down, she felt a light breeze brush against her genitals, particularly brushing against her pubic hair. 'I'm not wearing any panties!' She pulled down her skirt a little, covering her exposed genitalia, as she continued walking in direction. 'I was nervous the whole morning... it's so embarrassing!'

Walking towards the entrance of the school, she thinks to herself once again, 'Today, in my birthday suit... I'll do it..." Walking up to her locker, Miki took out her key, unlocking the metallic structure gently, before she opened it, a small 'clack' sound forming, taking the item inside it.

There could be a variety of items that could be inside that locker. Miki is an exhibitionist, after all.
