I think sometimes not knowing what they are talking about helps with the immersion. If in English they keep saying that they are my stepsister then it is hard for me to get into the story because I have never had a stepsister. But if I don't understand that that's what she is saying then I can make up my own words. I also think all studios would benefit from keeping the stories more vague. Instead of saying "hey, come here pizza man" say "hey, come here sexy man" That way if I want to be a delivery guy then I can still imagine it but also anything else.

    rerun119 There definitely are some JAV videos I can think of that would fit that "don't need to understand it" criteria, that I'd be turning the subs off for. Mainly impreg/breeding videos; that completely turns me off, but I can still watch the JAV videos containing those kinks because that aspect is completely moot if you can't understand whenever she says it.

      rerun119 But if I don't understand that that's what she is saying then I can make up my own words.

      Even for English speaking scenes I often just turn off the sound and replace with erotic music so that 1) I’m not locked into someone else’s story line, and 2) I don’t have to endure the over the top moaning and excessive profanity which for me is often a turnoff in most American porn.

      For this reason I love foreign language scenes left as is, especially French and Russian which are particularly sensuous. Then I get to make up my own plots and hear the sensuous female speech and moans.

        don't even need to have a lot of SUBS...just a few key ones here and there

        on pornhub...some with subtitles were extremely erotic

        one line here and there and you're off to the races

          talk about some decent motivation to learn a new language...VR porn 🙂

          You don't need to learn japanese, people are translating JAV VR using de Google's IA... 😉

            The situation with western payment companies and JAV have been an issue for a while, furthermore the new laws that have come into effect with JAV where the films are made then they have to wait a few months before release where the performers have a "cooling off" period to decide if they want it released or not will cause a delay with normal jav releases as well as the already niche VR niches,

            Eitherway F in the chat for Hitomi's retirement before she went all out and made more than just three vr movies

            it was kind of a joke btw

            people, in general, should want to learn some new languages...most talk about it and NEVER do it.

              metaverse
              I know them from 2d porn, was excited for a bit till i saw it's only 1080p

                metaverse It's interesting, uncensored which is nice, but unfortunately seems like they record in 30 fps, so it's hard to watch

                  Chinese porn with fake tits... 🙁

                  JAV vids don't SEEM to be on first page anymore....been a few weeks. not sure that is statistically possible with how many they make.

                  they used to be on the first page...thought they were just added as they came...we just keep hitting the NEW button

                  are they being suppressed in a way?
