Whether watching action pic performers Rinko Kikuch and Shioli Katsuna or erotic movie stars Akiho Yoshizawa and Reiko Yamaguchi, it’s clear Japan has cornered the market on flexible film starlets! This is especially true when it comes to Tokyo ingénue Yuma Asami. Although the curvaceous cancer survivor works as a singer and songwriter now, she used to be an adult video actress and model. With more than 600 skin flicks to her credit, Ms. Asami’s bulging resume makes Mr. Skin’s eyes (and pants) bulge too. Yuma’s youthful looks, ample orbs, and onscreen charms helped propel her to the top. In fact, the skintastic stunner was so popular, she became a member of the pop group Ebisu Muscats (featuring fellow porn stars Sola Aoi, Akiho Yoshizawa, Tina Yuzuki, and Aino Kishi) from 2008 to 2013. In between that time, the AV Best Actress Grand Prix winner won us over with her revealing role in the martial arts fantasy Ninja She-Devil (2009). As an alluring assassin, the dead-sexy character is trained to use all of her assets as weapons, including her killer curves! After bathing together in a hot spring, the topless hottie and her sizzling co-star Lemon Hanazawa dry off to display their naked T&A while clam-slamming! If that’s not arousing enough, the naked knockout shows off her ravishing rack, rump and muff while being seduced by a dude — proving this she-devil is really a fallen angel. Either way, when Yuma’s left breast pops out of her kimono, you’ll get a ki-bone-o!
