Let's see! For me the best out there come from yoshihara yuki-sensei. The artwork is just so smooth and clear, the stories always so funny and tender. You think that you can feel the heat and the softness of the intercourse...
And there is also shinjo mayu-sensei with her famous kaikan phrase, but well imo she can't reach yoshihara-sensei, but that's my opinion.
There are some anthologies out there quite good. From one of them,
Kinjirareta Ai no Kajitsu, "I want" from Masami Hoshino-san was one of the most touching smuts I've ever read. ( No idea why these lines are in bold!)
In the mature section, I should point out Anatolia story by Chie Shinihara-sensei and Ayashi no Ceres by Watase Yuu-san, and ai-ren by tanaka yutaka-san- they have great story as well as sensitive depiction of sex scenes. Ah the beuty that anime deny us...
I'll add more infos later
