To say that this wasn't what Liam expected when he had decided to become a vampire slayer was an understatement. No, he had expected blood and gore and dangerous battles, maybe some close brushes with death, but this was definitely not covered in the handbook (or would be, if there was a handbook). This being hiding behind a dumpster as he watched two vampires in an alleyway, one of them on his knees and the other with a hand in his partner's hair as said partner bobbed up and down.
