I, too, like seeing the model tied, stripped, manhandled, etc; it's an excellent way to start out. I'm not complaining though--this was the kind of tough bondage I like to see.
Watching someone do something for no reason--another batch of pixels churned out by someone who’s just doing a job--gets old fast. Lochai seems almost deferential--rather than playing with his latest toy, he’s there to give her a good time and then he’s done. Maybe he has a good poker face, maybe Bobbi had strict limits and he was bored, but there’s a strong sense of detachment here.
