Blood Bank
It’s not healthy in the few first chapters, it feels more like torture than BDSM, but after that they come up with a safe word and stuff. Vampire sub and a human dom. There’s also plot besides sex.
My Destined One
Short, non-toxic relationship with an alpha who thinks he’s a beta and an omega. The alpha is kind to the omega. A trigger warning for implied sexual assault (not between the main couple). Not a deep plot at all, wouldn’t re-read it, but it was cute while it lasted
The Last Zombie
Zombie. Very short story, no abuse or SA, read if you want something quick and not that deep
