Sakura Maid 3 (2016)

Sena’s master has yet to return home, but another mysterious guest has appeared at her front doorstep. Supposedly hailing from the Iron Cliffs, Ladon is an ambassador of dragonkind, a species that has long thought to be little more than a myth. Ladon intially desires to speak with Sena’s master, but due to The Master’s absence, she chooses to wait for her at the manor instead. The two of them gradually grow closer as they spend time together, eventually desiring each other’s company in a far more intimate way.
