my favorite BJ artists are: (but the exact ranking is a tough call, based on skill rather than number of movies, and of course looks play their part)
God tier: Yuuno Hoshi Hikaru Yukino Tsubomi Mika Osawa Sayaka Aishiro Azusa Ayano Megumi Shino Ryoko Hirosaki
Near God tier: Yui Hatano Rio Takamiya Hikari Hino Nagomi Yui Kawagoe Maya Maino (didn't do many movies but great BJs) Sayaka Aishiro Shion Fujimoto Alice Hoshi Riona Minami Rina Fukada Shizuka kanno
Yuuki Mayu Honoka Mihara Kiritani Matsuri Marika (not Marika Hase) Ryoko Mizusaki
Top Tier: Lisa Kasumi Asami Ogawa Yuu Kawakami Ryoko Murakami Rina Fukada Misuzu Kawana Ayumu Sena
Akiho Yoshizawa Miku Shindo Kururugi Mikan Marie Konishi
Also, I'm surprised there was no mention in the main list, as far as I can tell, of Mika Osawa and Ryoko Hirosaki. Those two could deep throat an elephant for hours, here are a couple of recommended movies if you want to check them out
Mika Osawa
and Ryoko Hirosaki
and a couple of great BJ movies by actresses that didn't do many movies in general
Maya Maino
and Marika (again, not Marika Hase) in one of my fave BJ movies (a rather old one)
I'll end this post with a couple of classics (old but still great BJ JAVs)
Ryo Takamiya (one of the best Irrumatio Jav of all times)
and Ryo Takamiya with Hikaru Yukino and Yui Matsuno
