In both Vampire: The Masquerade and Vampire: The Requiem, a blood doll is a mortal who freely lets vampires drink from them. Frequently found as members of subcultures such as the Goths, blood dolls seek a perverse thrill from the vampire's Kiss, but their tendency to actively seek out vampires to give it to them means that they unwittingly walk a very thin and dangerous line with their lives. Blood dolls often end up in one or more vampires' herds, though they rarely become ghouls or earn the Embrace. Many blood dolls escalate their masochistic impulse by sharing their blood with one another in a perverse (and extremely dangerous) parody of the Kiss.
