Facefucking occurs when a persons mouth is vigorously and repeatedly penetrated with a penis. Typically this is a male penetrator/female penetratee situation but can be performed by a woman wearing on a strapon, reminiscent of pegging, or as a part of such a scene. Facefucking is termed Irrumatio, as opposed to Fellatio where the mouth is moving on the penis. This can also be called skullfucking or throatfucking, though face- and skull-fucking do not necessarily involve the penis entering the throat.
