Sorry, I'm not clear on what the typo is here.
If I had to guess, it looks like its an anal scene, but there's a part where it says 'Her
pussy grips tighter onto you, rippling around the entirety of your shaft', and then mention of her pussy gripping nothing, and then a part where it's clear that your inside her anus.
If I had to speculate, it seems they were pointing out some inconsistency with the chosen parsers or scene description. But that's above my pay grade.
