Milk Doll Ojou-sama [English], by Ei Itou

Errr… Wut ? ^^;;
This is the story of a girl from a very rich family, who wants to escape an arranged political marriage and finds shelter at the house of a commoner, a former house tutor of hers. The sensei gradually teaches her the way of the flesh, blah, blah, blah.

The art is below Ei Itou’s usual standards, and the censorship is annoying, but I could at least laugh hard at the extreme naivety of the girl, in itself, it’s worth seeing
