Shameful Nude Model. (Pixiv:August 1, 2015) (Patreon)

    Ema prepared donuts laced with sleeping pills and tea laced with diuretics.  The reason for adding the diuretic was that she thought she could see Aoi's expression of embarrassment by making her diaper dirty.  This idea came true, and Aoi blushed and cried. Ema smiled with satisfaction as she drew that expression.

    The last two pictures were drawn from scenes that came to mind while watching the animation.

Since there are more than 10 images this time, I've attached a zip file to save them.
