I Picked Up a Demon Lord as a Maid

What would you do if you got yourself a big-breasted maid? This maid even has silvery hair and red eyes like a goddess. That sounds… kinda awesome… But… wait… wait a minute… how can my maid be the demon lord? That's not how this was suppose to go!? My dear Demon Lord, please change out of those clothes and I will take you home right away.
