MILF pornography

MILF pornography ("Mother I'd Like/Love to Fuck") is a genre of pornography in which the actresses are usually women ages 30 to 50, though many actresses have started making this type of pornographic film at age 25. Central to the typical MILF narrative is an age-play dynamic of "older women and younger lovers", both males and female. A related term is "cougar", which implies an older woman is acting as a predator.
Overview.
Actresses of the MILF porn genre have their own awards: the XRCO "MILF of the Year Award", the AVN "MILF/Cougar Performer of the Year Award", and the Urban X Award for "Best MILF Performer" among others. In Japan, Adult Broadcasting Awards also has an award for the "Best Mature Actress".
In the UK, the term "yummy mummy" is used as well as MILF. Oxford Dictionaries defines a yummy mummy as "an attractive and stylish young mother".
History.
The term MILF was first documented in Internet newsgroups during the 1990s. The earliest known online reference is a 1995 Usenet post about a "Playboy" pictorial of attractive mothers. It was popularized by the 1999 film "American Pie" referring to Jennifer Coolidge's character, "Stifler's mom".
