Two Sex and Maneemon

This shunga has some interesting information.

First,
It seems they are teacher and student of class.
I don’t know what class..

Second,
Why the cats also make love…

Third,
Look at under table.
Maneemon!!
He is looking furtively in their sex!!!

And one more thing,
The text under the cats is Japanese current national anthem!!
