Seeing that my first thought was that Edward decided to come back again under different name and extra fetish for spanking rather than body hair removal :)
I hope we got a decent replacement or maybe the reason he left was exactly why you decided to take his place? :)
Yes, ending was a little plain and story itself is pretty straightforward but everything is perfect and pleasant to read. Makes a good world introduction to see how things work there. Maybe in the future works you will add some more interesting plot twists and some intrigue :)
