A type of oral sexual intercourse performed by someone actively thrusting their penis into their partner's mouth and possibly their throat.

The distinction between [[fellatio]] and irrumatio is based on who is actively moving: irrumatio means to thrust the penis into the partner's mouth, while fellatio means to move the head and mouth up-and-down around the penis.
