KAWD-800 - Underground idol Momo Ichinose loses control and experiences her first explosive climax

Did the director change since the previous entry with Riona Murakami? Because this is a total failure as a 'pee' fetish film. It relies way too much on the vibrator, making it tedious and unwatchable. The ending just looks like bullying. Does the director not understand the appeal of this genre? (The previous 'pee' film with Moe Tenshi wasn't good either.) The actress is great—she's got that Yuki Mayu-style 'pretentious underground idol' vibe—so it's a real shame. It's probably impossible, but I wish the previous director would remake it.
