Boobpedia:
Greta Carlson is familiar to many pornography viewers as a model in a phone sex advertisement often inserted into the beginning of many videos. She began her career in 1991 and continued until 2002, engaging in nearly every genre. Carlson is well known to readers of Harmonys and House of Milans bondage magazines and videos as Allison Brach and Greta Carlson. Where as many models chose to portray the damsel in distress, Carlson often presented herself as an active (and enthusiastic) participant in a bondage game.
