I don't know even one single movie where Yuma Asami swallows it all. She plays with the cum (sometimes A LOT) but never swallows, i guess she doesn't like it. Same goes with Tina Yuzuki, Nao Ayukawa, Sora Aoi and many many more. It looks like they don't need to do that kind of stuff since they're superhiperstars. Nana Ogura is exactly the opposite, she's a superstar but she LOVES to swallow, and no matter the movie is about, she likes to suck it dry, which is so rare to see, because in every movie i watched of her, she always swallows.
