Senior bodybuilder Chiaki Yumoto makes her AV debut in Ruby's AV industry at the age of 50. She's been going to the gym for a while, so she doesn't have a big belly for her age, and her thighs are plump and strong. When you see a sporty person like this, it gives off a healthy erotic vibe. She has a refreshing and easy-going personality, and apparently agreed to appear in an AV after being encouraged to do so by her boyfriend.
