An excellent and very educational series. About a newlywed couple who are virgins and their comedic ups and downs in learning how to have sex. Not really a hentai, though there are scenes which can be called hentai. Tastefully rendered taboo themes. A funny how-to-guide for sex illiterate and experts. Even though this is not for children, it may be suitable for older teens, let s say 16+. WARNING: For a mature or adult audience only due to nudity and adult situations.
