when a chick gets her boyfriends dick, or cock, shoved down her throat during oral sex.
some girls might want to be deep throated instead of just having the dick in their mouth to avoid the taste when the guy cummes all over her. they also might want the dick that far back to avoid making a scene and having to pull away to spit the cumm out. this way, the cumm just goes directly down the throat. oral sex. ;P
"can you deep throat me so i don't have to taste your cumm.?"
