I must be the odd one for all this. I disagree mostly with that having the stuntcock show ejaculation/orgasm is important in VR. I do not care at all as I do that on my own at whatever part of the scene is best, which is usually at a place the girl is really into it. As imho it is far hotter to see the girl realistically orgasm her mind out, legs shaking, moaning, etc. (or at least is skilled at acting it out somewhat believable).
I guess in a way this is probably why I also could not care less for BJ parts in scenes, 99% of the time they are so non-immersive to me I always skip it. Especially BJ to orgasm endings in scenes are just a waste imo, or at least never the part I watch as the ehh.. "ending highlight".
However I do think "cum covered fucking" is really hot (sadly it's not a tag but it should be). So if they do cover a girl's body, boobs, or face with cum and then continue fucking, that's hot (at least if the girl is very into it). Again sadly this rarely happens and if it does happen they often do a cut where suddenly the girl is all cleaned up again. ðŸ˜
Note with "cum covered fucking" I don't mean a complete body bukkake like 2D porn has in 10-on-1 gangbangs, just normal 1-on-1 action is best although 2guys-on-1girl can work for this too. There's a subreddit that decently shows it at /r/cumcoveredfucking/
