thanks for the upload but I don't think the artist would be the name of the first hentai, with that said this guy: Komai, Kazuya has taken part in everything except the taimanin hentai, according to myanimelist
edit: at a glance 01-26: Kansen Sodom 27-40: Seikou!: Osananajimi wa Terekusasou ni Uso wo Tsuku 41-58: Aneki no Kounai Kaikinbi And than I think just Taimanin Yukikaze episode 3
