The protagonist, "Nene", has a desire for exhibitionism...
She has difficulty talking to people and expressing herself, and has had difficulty blending into groups since her childhood, she always spent her days alone in the corner of the classroom reading a book. She was unaware of it herself, but she had a secret desire to expose herself, and this time it blossomed into a sexual fetish for exhibitionism. She lacks confidence and hunches her back, making it hard to tell, but in fact she has huge breasts.
The setting is in a late-night city...
You can expose yourself in the residential areas, in front of vending machines, bookstores, parks, under bridges, convenience stores, in back alleys, near telephone poles, in apartments, on trains, and in apartment elevators!​
