A type of oral sexual intercourse performed by actively thrusting one's penis into a partner's mouth and 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.
