Voyeuristic Masturbation Scene
A playful yet erotic shunga where a young woman secretly spies through a sliding shoji screen as a couple makes love on the other side.  Caught between curiosity and arousal, she pleasures herself discreetly, her flushed expression revealing her excitement at the forbidden view.
 
This composition highlights the layered desire often found in shunga—sex observed, imagined, and enacted all at once.  The bright floral kimono contrasts with the intimacy unfolding beyond the screen, adding a touch of charm to this naughty voyeuristic moment.
