A slim waist has always been a hallmark of beauties throughout Chinese history. In those bygone eras without advanced cosmetic surgery, true beauties were undoubtedly born that way, as certain body parts—like facial features—couldn't be altered through external means. However, there was one exception: the belly, which could be modified to some extent. Ancient texts were full of praise and embellishments for various body parts, but the belly rarely received any accolades; even in the Tang Dynasty, which celebrated plumpness as ideal, a protruding belly was seldom glorified. The Tang pursuit of plumpness didn't last long; by the mid-Tang period, it had shifted back from "plump and rounded" to "slender and graceful." Descriptions of slim figures focused primarily on the waist. The slim waist became the ultimate symbol of beauty, and from then on, it represented a lithe and attractive form. After the mid-Tang, slenderness once again became the standard for beauties. In the works of literati and poets, phrases like "fine waist," "Chu waist," and "petite waistline" appeared everywhere. Thus, lines like "A person is slimmer than the yellow flowers" weren't just poetic expressions—they reflected a real phenomenon. By the Song Dynasty, a slim waist had essentially become the primary emblem of female beauty. This newcomer, Saki Kiyono, would have been unmatched in that era with her waist; it's a mere 52 centimeters, which is under 21 inches, leaving over 70% of actresses in the industry green with envy. Then there's her styling—it's easy to see that this girl was a ballet dancer before, and just from the cover, you can feel how incredibly flexible and smooth she is. She must be able to unlock all sorts of advanced positions while getting intimate with her co-stars! You might be wondering about that "genius girl" tag on the cover... The answer is that Saki Kiyono, aside from being a skilled ballet dancer, placed in the top three at a national Japanese competition, so calling her exceptionally talented isn't an exaggeration. As for why Saki Kiyono decided to become an AV actress? The label "kawaii*" describes her as: "Welcome the horniest girl from the Japanese ballet world to her debut—life is full of surprises." So, I guess it's simply that Saki Kiyono has an insatiable sex drive that she couldn't resist, leading her to dive right in. We're no strangers to actresses with ballet backgrounds; we all know their strengths—and Saki Kiyono is no different. In her videos, she'll slip into ballet attire and perform a routine to prove her top-three national ranking wasn't just for show, then showcase her AV talents, like furiously riding her co-star in a wizard pose or treating his manhood like a gymnastics bar for some playful fun. Soft and flexible actresses aren't rare, but in my opinion, Saki Kiyono has massive potential. The last one I pegged for success was Sara Uryuki, and here's why I'm optimistic about her: In her videos, she's way cuter than on the cover, and every viewing gives a different vibe—first, she looks pure and refined; second, there's a seductive charm; third, you sense a bit of naughtiness. Compared to other newcomers in the same batch, she doesn't fall short at all. Plus, even with her super-slim 20-inch waist, Saki Kiyono has a pair of perky, full breasts, paired with well-defined abs for a flawless, toned physique. And though she might not seem tall, her proportions are spot-on. By the end, I wasn't even thinking about her national ballet ranking—I just thought it'd be a blast to get cozy with a girl like her and maybe even try some ballet moves together!
