I'm not fully understanding your comment. Do you mean when the girl breaths through her teeth? I haven't noticed this at allmost annoying thing about western vr is the breathing in sound they make, breathing in through their teeth. And like some said earlier, too fast. I have seen jav vr in 4 parts where 2 of them have no sex at all.
Or, do you mean the guy? I'm actually probably unusual in that I don't mind at all if the guy makes some noise. I'm a little tired of porn where the guys are completely silent. I mean, how realistic is that? Even in VR... somehow I seem to be able to trick my brain into thinking the sounds are my own.
