I read this a while ago and was trying to find it, but i never saved the link.
They were three fantasy stories. One part was focused on a vampire, the next a werewolf, and the last one was an angel. I remember bits an pieces of the story.
For the vampire story, I remember the main character was on the run because the antagonist wanted to take over his body. In the end the main character was taken over and had to watch himself have sex with the antagonist while his mind slips.
