Creampie, AKA internal ejaculation, internal cum shot and, in gay pornography, as breeding, is a term used in porn to explain when a male ejaculates inside his partner's anus or vagina.The term also makes reference to the visible seeping or dripping of semen from the anus or vagina. Scenes of this type have become typically found in both male homosexual and hetero pornography since the turn of the 21st century.

Creampie, also named the "reverse money shot" by scholar Tim Dean : semen flowing out of a woman's vagina after sex without condoms 
Internal cum shots are a comparatively current development in pornography ; they are not found in early lewd films.The usage of the word "creampie" to describe such scenes came from U.S. Pornography in the early 2000s.Internal ejaculations, followed by pictures of semen oozing from the anal sphincter, are a standard staple of bareback gay pornography, where they are also referred to by the term "breeding".Breeding is frequently followed by felching, which involves sucking the ejaculate from the partner's anus.Some racy films use an artificial semen substitute to simulate or augment creampie shots.
In straight pornography, intercourse is historically followed by a facial or other visible ejaculation.[3] Creampie scenes depart from heterosexual racy convention in favor of a depiction that closer mimics sex as performed in normal life ; they've been called the "counterimage" of facials. Following perhaps the example set by gay porn, they have become a popular subgenre inside straight porno since the turn of the century, featuring both vaginal and anal ejaculations. In some creampie films, both gay and straight, intercourse and internal ejaculation are followed by performers licking up the ejaculate that has dripped from their bodies. 
Examples of hetero racy film series featuring creampies include Cream Filled Youths and Internal Cumbustion. In male gay pornography, TIM is a notable representative, its title Breed Me in the 90's having been noted as one of the "earliest and most scandalous" in the category.
