Most scenes feature short plots of women irritating or insulting men, (i.e. bitching wives or girlfriends) behaving mischeviously or else finding themselves in a unfortunate position, and as a result they are throated.
The series started in 2000, and was one of the first to feature gagging and throat fucking and is said to be responsible for starting the porn niche, spawning numerous new throat fucking series since. They often proudly claim that their series is "The best throat fucking ever lensed", and that "Gag Factor has made more men ask women for gag sex".
Unlike similar series, Gag Factor tends to push more on themes of degradation and humiliation. Though they often engage the action with the woman on her knees, their signature is to have her lay down with her head hanging off the edge of a surface, letting her saliva run down over her face and hair. Often the female is verbally assaulted and encouraged to gag as they are throat fucked, while handled very agressively and forcefully by a seemingly mean spirited male. Other common signatures include face spitting, throat grabbing, and holding the female's arms down while viciously throating her.
The series has won several AVN awards for best oral series, and best oral scene.
