Recognised the clip, it’s from an hdoujin game called “Iris Action”.
Here’s the [Gelbooru link](https://gelbooru.com/index.php?page=post&s=view&id=1362486) for the clip and there’s some links in its comments section. However, the primary download link is non-functional (and also would be in Japanese) so good luck to everyone on a hunt to find a working one should you do so.
P.S. It’s the top rated post for “tentacles plant” on Gelbooru so they agree it’s good too.
