Artist's commentary
Flan-chan found the books hidden under the bed
Books found: A slightly naughty photobook
Flan-chan was only taught a limited set of knowledge by her big sister.
On the topic of having children, she still believes in the storks story.
Whether you want to teach her the specifics of it depends on your conscience.
