Ling is an esthetician from Chiba who is obsessed with female underground idols. Her hobbies are going to concerts, buying merchandise, and getting excited by cute idols, but she makes all the money for it by creampieing them. Since her first experience, she has been addicted to raw sex without a condom and without permission. It's an easy job to do creampies since she can do the raw sex she loves and do her favorite idol activities.
