Because a whole lot of them either get really lazy with it or don't just transfer what they're doing on YouTube as NSFW versions. I like how some creators actually have YouTube and OnlyFans versions of their videos because it shows how easily it transfers. I'm pretty sure Puffin has a small amount like the Vampire series.
You could say I have a "face-fetish" if I can't see girls' face it''s a no-go for me and honestly it feels like a such cock-block when she doesn't show Her face even tho she clearly did in the past dozen of times already it's just annoying at this point. I mean I kinda get it - teasing like that kinda works when you want to keep simps on a short-leash but I assume it's more about her mental problems than actual PR thing behind it...
I don't think it's that odd, no-face just makes it far more impersonal than simply pulling the camera back and completely misses the point why people liked the previous 3dio topless video. Puffin seems very much like she's never going to go that fully nude route where the most you're going to get is bare ass and tits. That's fine but she should do it more often than she does.
