I might just give my 2 cents here.
When I first get into JAV VR, I experienced similar thing, I get attached to girls. I remember I watched a lot Haruka Namiki those days, and from all those VR intimacy the attachment build up. Then you feel kind of jealous when you watch her normal JAV in which she get fucked by others.
Later I understood that is just how Oxytocin works. Oxytocin triggers both intimacy and jealous feelings.
And the jealousy part is not all bad, it can actually enhance the VR porn experience, if you are into this kind of "emotional SM".
I still can not enjoy NTR movie, that is just not consensual and pure torture, but I find the perfect amount of jealousy for me is swinger movie.
I first found out I really enjoy swinger porn when I read a hentai called Karami Zakari. Japanese hentai artist really know how to play with your feelings. It also got a JAV adaptation.
If you are curious I recommend read the hentai manga, the JAV adaptation dose not catch feelings well because bad acting lol. the manga has 2 volume, volume 2 got too extreme for me, kind goes to full on NTR territory.
After I found out I have this kink, I begin to search for swinger JAV VR. Actually there are a lot. And these Japanese director really get it, they really understand how this works.
this two are my fav. all around well made, and these kind of movie involve so many people really challenge the director's ability. I really appreciate the orchestral chaos feeling it get in the final. not too messy but also feels like real social interaction.
and for this one. The director purposefully let the cutest girl be alone with you first and let you get attach to her before everyone else showed up, but when the action start, the director let every other guy fuck her before you. That is some emotional gut punch and I love it.
