[Cocomachi] Holding in my pee while sheltering from the rain

A lone schoolgirl in a school uniform shelters beneath a structure as rain lashes the trees and pavement, her full figure tense with the need to get home and cool off after drinking too much water. She admits that she has to pee but cannot let herself go, clenching against the urge as the waiting turns her face flushed and her thoughts frantic. The tension finally breaks beneath the downpour: she gives in and pees in the rain, finding an oddly intense release in the very weather she had been hiding from.
