Attractiveness doesn't really matter because that's not what we're talking about. Sure, people enjoy seeing certain faces, but this is mainly about BJ skill. Aika and Sora Shiina are not good but they are some of the best riders currently. Everyone has their strengths. BJs are now among theirs.
Yuuno Hoshi is one of the most celebrated BJ givers in JAV history though. I don't think she's overlooked at all. She's just retired.
What one name do you recommend as the "it" girl for blowjobs now? The YUUNO Hoshi of today...
