well lets say that i prefer (for example) Aimi Yoshikawa 10times over the "great"(?) Yui Hatano...i never noticed/recognized her for quite a while, then i gave her a "chance"..
and she didnt impress me at all, there is something "bland" about her and that allways "fake" smile...not my type for sure
Aimi is SUPER hot. Performance-wise though I think Yui still bests her in every way, especially blowjobs.
I just find Yui more adaptive to different kinds of movies right now too. Also far more seductive.
