Saigado is a very famous circle led by the artist Ishoku Dougen and has drawn a shitload of great hentai manga and doujinshi comics. Limited by my time, now I only share my favorite series - Hana’s Holiday and its Second Season. The story is about a girl who has learned to be attractive starts hunting on her holidays. She often wears an outfit without bras or pants inside, loves to expose her body before handsome men and has sex with her favorite types, one or more guys together… It’s a pity that such a well-drawn manga hasn’t been completely translated into English. The English version (translated by Tonigobe) is only available for the first 5 chapters of Hana’s Holidays so far. To view full set of pictures, you need to download the Japanese raw version or the Chinese version.
I will add more of this circle if needed and time allows. To other works by Saigado, most of them are very easy to be found by google elsewhere, as well as my partner sites. If you feel really difficult to find any more, please feel free to tell me the titles by leaving a comment here. I, or maybe other people here, will try to help you find it.
