I think what a lot of VR porn lacks is an intro that gets you really warmed up and turned on.
The old school Evil Angel and Service Animals DVDs would show a girl walking with a tracking shot of her ass or show her bending over doing something or dancing and shaking her ass. Even if it's not part of the overall VR story, you could shoot it in a VR voyeur way like we're seeing her doing something really sexy.
I saw a NaughtyAmericaVR intro where Gia Derza had oil poured on her ass by another girls where it was really shiny and sexy, and then she sat on one of those large gym bouncing balls and just bounced on it really good and I thought that was a really good warm up type intro.
Another warm up type intro to consider is having the girl do the ahegao face where they cross their eyes or roll their eyes and stick out their tongue and show all the saliva running and dripping down and off their tongue and then smile after playfully. There are examples on YouTube...

Most VR porn that does ahegao inserts a few moments of it in during the sex but it's usually not very long or well done. It's kind of like you want to see it during most of the sex if you can. I think one way around this would be to have it as part of an intro that really warms you up. Almost like you're watching 20+ different attempts of it back to back in a YouTube clip from the same girl. I think it could even be cut in a way where it's in different locations, positions, outfits, wig/hair colors, etc. one after the other in VR as a VR warm up intro. You can look at all the YouTube and Belle Delphine ahegao example videos and just do a bunch of those in a row for the intro.
Maybe she's a cam girl doing it on camera for her fans in her room and announces a contest where one of her lucky fans will be selected for a special night at her place. So you get lots of ahegao on the intro like you're watching her on cam, then when you show up at her place and she does it for you in person and smiles and laughs. She does it again during the blowjob, having her saliva drip and run down her tongue down onto your dick. And then during sex it drips and runs down her tongue onto her chest and she rubs the saliva all over her nipples and breasts. So you get a lot of it on the intro playfully and you get a lot of it during the bj and during sex.
Coco Lovelock is great at rolling her eyes into the back of her head in Wankzvr Coco Offcam, you'd just have to get her to cross them and stick out her tongue long enough that saliva starts running down it. If you wanted to go even further with it, you could have two girls doing it, or even consider an ahegao harem where saliva is just dripping from lots of different girls tongues all over the places as they moan and act really cute and smile after. Maybe start with one girl to see how well it does.
