KRMV-970 - Provocative High School Girl's Lewd Self-Pleasure for the Camera

To be blunt, it's a total stretch. The reason is that one of the cast members clearly looks like she's in her late 20s. Watching someone like that act like a high school girl is just... yeah. If that's the case, maybe the 'Office Lady Masturbation' series from the same studio is better?
