It's interesting to me because when the video starts she's actually doing something pretty common for a good cam girl: laughing and looking like she's having fun. Even the button fumble could be cute and exciting to the right audience, and played up. And then no tease, no flair, nothing, just yanks them out for inspection and immediately goes cold dead fish face like in every single non nude she's ever taken. It's really startling to watch how quickly she gets bored and doesn't try to hide it. It's so clinical and gross. She truly has no idea how eroticism works. She's just wandering around going "herr derr titties" and thinking that's it.
You don't have to be hot to make it as a cam girl but if you're not, you've got to know how to project fun and sexy and that bored dead fish face ain't it.
