Crave by Georgina Kiersten
"Crave: A Short Vampire M/M Dark Erotica Story" is exactly what it says on the tin. It conveys an impressive amount of worldbuilding in just a few pages, without being distracting if you're mainly here for the human/vampire sex.
It's pointedly diverse, in a good way. I liked it overall, and I would recommend it to someone looking for diversity of representation in erotic fiction. It does have some cws at the start, so check those out before proceeding, as there can be overlap between kinks and triggers.
