A story about having sex with a classmate who forgot her panties.

Onizuka-san is a gyaru who's both slightly naughty and clumsy.
She's already well on the way to school when she just realized that she forgot to wear her panties...

An introverted male classmate of hers happened to be passing by at the moment.
He secretly has feelings of love for her, so he mustered all of his courage to try to help her out:
"Would you like to wear my underwear instead?"

And so he finds himself alone together with a naughty gyaru inside a public restroom at a park.
This won't end with just some underwear transfer...
