irrumatio 

The act of thrusting of the penis into the mouth of a partner. The penetrative partner (the irrumator) engages in motions by moving his hips and body in a rhythm of his own choice, in contrast to the standard act of fellatio. A form of oral intercourse, irrumatio is commony called facefucking, skullfucking, and when penetration is deep, throatfucking.
