I assume that you are website is brand new. It is not unusual, it can take some time before Google discovers your website and indexes it in the search results. You can speed you this process a bit by adding some good content (be it new posts or videos) and doing some regular SEO like adding backlinks, adding and configuring the plugin like YoastSEO. You also can submit a sitemap to the Google Search Console and this alone should speed up the whole process. Obviously, for reasons like spamming and other ones, it takes a bit longer for a new porn site to be indexed.

It does look great but I have a feeling that your video titles are overoptimized. You are adding too many keywords in titles and it does not look natural.

For example the title: “Three hot Japanese having lesbian porn threesome sex” should not include the words porn, sex and threesome in the same title because saying “Three hot Japanese (girls) having lesbian sex” is enough and Google already will count “three girls” and “having lesbian sex” as threesome porn so you do not have to put these keywords in every video title.

I would say better to edit them manually but there are not many videos on that site so it should not affect that much over time when you will have hundreds of videos posted.
