Edging videos are my favorites. I can only give tips about what I enjoy--I'm not a producer or director.
First tip: Study Mark Rockwell's flat POV videos on Pornhub. Try to capture that feel/mood/attitude in VR.
Here are some more ideas:
1) I echo K53Ln25z's comments about about JAV videos and how close the girls get, kissing, etc.
2) Keep the action going, but sometimes it should be very slow and teasing, and sometimes speed it up.
3) Unlike abcrebel, I like seeing the guy's dick. It increases phantom sense.
4) The male performer should not move too many times into other positions, other than to slightly adjust position so the girl can have better access to his private parts for whatever position is happening.
5) I don't like much undressing or teasing before the real action starts--get right to it.
6) I like them to be at least 20 minutes long. 30 minutes is better.
7) The performers need to seem spontaneous and like they are having fun.
8) I like plain black or white backgrounds; they seem more immersive to me, but I know that isn't everyone's preference. Also, who knows? That might be boring if that's all that's a studio did.
9) I like it when the guy blows a massive load. I'd like it if the cum shot was repeated in slow motion after he's finished. I've edited a lot of videos for my own personal use to do this.
10) I often play binaural beats or hypnotic trance music while I'm watching editing videos; it helps me get more relaxed and immersed. This would be cool to have built in to the videos.
11) In addition to number 10, the girls could use NLP/hypnotic phrases to intensify the effects and get more immersed. When done correctly, it is like natural speech. I would be happy to write some for a studio who wants to include this.
12) I love two girl edging scenes, but VR Edging took some time to get them right. This one is just about right:

13) This JAV is one of my all time favorites, despite the pixilation:
