[Congratulations! 30th Anniversary of AV Debut] This project was launched because we wanted Na-chan to change, who is worried about her increasing fat and decreasing sexual desire as she ages! Chubby Nacchan is also attractive, but I want to shine once again as a mature AV actress! This is a close record of the three months I spent with her. I live a stoic life with muscle training → dietary restrictions → sex. I was depressed because I ate secretly.
