throat fucking

Irrumatio (also known as irrumation or by the colloquialism face-fucking) is a form of oral sex in which someone thrusts their penis into another person's mouth, in contrast to fellatio where the penis is being actively orally excited by a fellator. The difference lies mainly in which party takes the active part. By extension, irrumatio can also refer to the sexual technique of thrusting the penis between the thighs of a partner (intercrural sex).In the ancient Roman sexual vocabulary, irrumatio is a form of oral rape (os impurum), in which a man forces his penis into someone else's mouth, usually a woman's.The act of irrumatio with forced vomiting is present in some online pornography, partly because of its shock effect and as a form of humiliation and degradation.
