[Celebrating 30 years since AV debut] We wanted to change Natsuko, who is worried about her increasing body fat and declining libido with age, so we started this project! Chubby Natsuko is attractive, but she wants to shine again as a mature AV actress! This is a close-up record of the 3 months we spent with her. She leads a stoic life of muscle training → dietary restrictions → SEX. She secretly ate and got depressed at times, but she worked hard! We will invigorate Japan's crotch with the new Natsuko!
