- Forcing a girl to deepthroat until such time as her gag reflex kicks in. This can often lead to girls throwing up during the scene. Often in Extreme sites, this is encourages and the filming continues.
Gagging also appears to a lesser degree in a number of blowjob or oral sites as girls are encouraged to try deep throating.
Some sites also have gagging as part of "hard" blowjobs. Often a girl is held in place and the guy literally fucks her face, jamming his cock down her throat, often causing the girl to gag.
