PRED-024 - Temptation Splash Instruction, Mao Kurata's explosive handjob class

What's up with the male actors at the beginning and end? If they're playing a teacher or a student, don't just show up—put some effort into the role. I guess the director doesn't even think about acting direction and just hires whoever. Both the director and the actors seem to think just 'doing it' is enough. Every chapter looks exactly the same. It's not interesting if you don't put effort into the situation. The actress is great, but the people making it are total amateurs, so it's a failure.
