TRAC-031 - I'll do whatever you say, Chiaki Takashima's 148cm close-up lesson

Honestly, her face isn't anything special, but I want to give her credit for working this hard while being in an idol unit. She wears daring outfits, shows off her front confidently, and handles the low-angle shots well. Overall, there's nothing that intense, so I have no idea why this is rated 18+. I hope she goes even harder next time.
