I'll just paste what I wrote on YP regarding the random rape thing: "Sara is pretty screwed up herself so I took Itsuki's act more as a warning. (Hell, she even says so.) She didn't get turned on until Miharu reacted the way she did if you look at the blushing and facial expressions. It went out of control, for both of them."
I cannot interpret this page as anything else than molesation:

Let's not forget that this is before she has been "warned" about the senpai, and knew anything about her intentions. And as for how the story unfolds, I still interpret it as the senpai taking advantage of a much less powerful and inexperienced girl. It doesn't matter whether her intentions were "I'm gonna sex her up" from the start or not. (Which I actually think she was set out to do.)
You might find it tiring, I find it wonderfully reliable and consistent. I know what I'm after when I read Asagi Ryuu, and it is always faithfully and dependably delivered:
A) hot, beautifully drawn yuri sex which invariably grows into a happy romance, where the sex is
I must disagree on this part! Some stories have bad ends (The Rites of the Moon Princess, that untranslated one which ends in marriage for the MCs love interest), and some stories are just sex without any kind of romance at all. (This chapter amongst others.)
C) a seasoning of harmless fetishes, some I like ("body size gap" would be a better way to put it than "age gap" in this and several other cases), some I regard as a guilty pleasure (saliva trails), and some I merely tolerate (watersports).
While I do like some of Asagi's fetishes, I wouldn't really call watersports "harmless." I think that one can scare a handful of readers away from his works. (Specially as the liquids he draws looks really... thick... in my eyes. Sometimes it's like the girls urinate gelatin.)
Personally I adore the way he draws fleshy bodies. I mean, look at the way those fingers disappear in her thighs:

And... watersports... isn't too bad...
In a world where reading yuri all too often contains unpleasant surprises, whether we're talking bad relationship endings or sexual elements that you didn't want, I value Asagi Ryuu's work for always being what I expect it to be.
I might have gotten involved in the yuri scene way later than you have, but I very, very seldom find elements like those in what I read. I feel that I can afford disliking stories even if they're void of sexual elements I dislike and the girls get together.
As for Asagi, I love his art, but not his stories. If I am looking to read a story that I'd like, I wouldn't consider him. If I was just looking for great looking art (or just porn) to drool at, then he is a valid option.
