There is a saying in the adult industry: "Watching porn without watching Sora Aoi is a waste of time." Why is Sora Aoi so famous? It is said that Sora Aoi shot more than 200 films in one year, which means she was almost shooting every day. Although these films basically have no plot and do not require much acting skills, doing bed exercises all day long must be tiring. I think even Olympic champions may not have her spirit.
