In an unintentional effort to revive the oldest thread in recent memory, I came across (ha!) this request and thought of one of my favorite films featuring Yuka Mizuno, ROE-124, which is more about female-led control than femdom, strictly speaking, but Yuka embraces the role of the domineering mother fully and convincingly. Similarly, there's an all-too limited series "嫁の母に浮気がバレて、寸止め生殺しSEXでたっぷりシゴかれた僕" (My Wife's Mother Found Out About My Cheating...") that includes JUQ-343 in which Yuka Tada exercises ejaculation control of her wayward son-in-law - again, this is more about control than femdom, but it's female-led and rich in storyline, two attributes I'd like to see more of in AV. JUQ-279 and JUQ-158 are the other two titles in this series (that I know of), and the former (with Maki Hojo) is worth checking out.
