I hate to disappoint you guys, but I am 100% sure that she will not get nude in the upcoming movie.
I just watch another pink movie from the same company LEGEND PICTURE. In that movie, the leading actress had a sex scene but did not get nude at all. One of the supporting actress went nude, who was a former JAV actress.
Similarly, Kei Fubuki, as the leading actress, won't be nude. On the other hand, the supporting actress Shindo Manami, who has already been nude in her publication, will show tits in this movie.
