As the name hints, this aims at showing the girls in various common fantasy outfits such as maids, nurses, etc, in pervy and suggestive situations or poses. There is some nudity but its primary focus is "sexy outfits", as well as lingerie. This was just boring though due to its basic art detail and overused too much in anime.
If you want to see some girls show off sexy underwear and typical fantasy outfits, watch it. Otherwise skip as there is very little engaging dialogue.
