There’s a tagging issue with this scene. The film features what I would call “fisting”, both anally and vaginally, but in both cases, the hand is not inserted fully. The tags for “Anal Fisting” and “Vaginal Fisting” on StashDB both say that it’s the insertion of a full hand.
In the anal part, only the end of his fist is inserted into her, but the vaginal part (which is officially labelled as “Fisting” by the studio), the hand goes in far enough that at least 4 of his fingers are fully inserted. The hand never goes wrist-deep.
There are no “partial fisting” tags, so I don’t know how to label this.
It’s strange that all “fisting” tags require the full hand to be inserted while a “deep fisting” tag exists. There isn’t really room in these spaces to go much beyond the full hand.
Some experienced fisters enjoy deeper penetration, referred to as “depth play”, in which hands may be inserted as far as (or past) the elbow.
Anyway, I previously shared some thoughts in this edit comment thread. Coming back to this question with a fresh mind now, I think it comes down to whether people care about separating out what might be considered “almost fisting” or “shallow fisting” or whatever. If not, I think it’s best to keep the existing set of tags and err on the side of “rounding up”, e.g. tagging the scene in question with both Vaginal Fisting and Anal Fisting.
My hunch is that people don’t care much about separating these cases, but my hunch is of limited value as I’m not particularly familiar with this niche.
