TXCD-018 - The Ice Queen's Secret: Katase Nagisa's Twisted Submissive Side

It's an older title, but I rented it because I wanted to see Nagisa Katase. Was 'Discovery of an M-girl' a series? I had no idea. As for the content, it's far from her actually 'discovering' her M-side. Sure, she gets restrained, but it's just light teasing and bullying. She never actually awakens to any M-pleasure. I don't mind a lighthearted tone, but the goofing around was just too much; it was frustrating. That might fly in some gimmick-based videos, but this isn't one of them. Please put some actual thought into the script and direction.
