One of the common types of sex in pornography is the Ass To Mouth (or ATM/A2M) in which the man removes his penis from a slut's anus and, without cleaning it, places it in her mouth or the mouth of another slut. The cleaning of the penis is excluded for the sake of increased sexual excitement. Pleasure (for the man and the audience) that comes from knowing that the slut is injesting fecal matter (present on the penis in a quantity so small as to almost always be invisible to the naked eye) which is unhygienic. When she does this, the female is expressing disregard for her own health and accepting the implicit imposition of the idea that her well-being is of no great concern anyway.

The female who performs an A2M on camera is a highly-evolved slut, fully conscious of her role/purpose and willing to give her body over as a tool for male sexual gratification. In her quest for a great orgasm of her own the slut may, or may not, derive sexual pleasure from doing things that are considered taboo. While some sluts are aroused precisely because of the taboos associated with playing with the anus, others truly delight in the experience of stimulating or being stimulated anally.

Ass To Mouth is a mainstay of porn where men are depicted as dominating/degrading the whores for the erotic pleasure of the (mostly) male audience. The appeal is that the sex is bad & shameful and the girl is dirty & nasty for doing it. Which is what truly great pornography is all about.
Jamming a few fingers in her ass to get it stretched out a bit, Ben pummels her asshole in some great anal action. Her ass gaping and her heart racing, Liv rides his meaty dick before taking it back in her mouth. After some good ass to mouth action, she takes it back in her asshole before he gives her a health dose of cum in her mouth.

"One of the newer marketing ploys in pornography is called "ATM" ("ass to mouth"), where the male performer anally penetrates a woman and then sticks his penis into her mouth, often joking about her having to eat shit. In this pornography the code of debasement is most stark. There is no apparent increase in male sexual pleasure by moving directly from the anus to the mouth outside of the humiliation that the woman must endure."

(Robert Wosnitzer et al, 2006, "Aggression and Sexual Behavior in Best-Selling Pornography: A Content Analysis", p. 23)
Men who enjoy the suffering and humiliation of women (="ass to mouth"), are diagnosed with paraphilia ("sexual deviancy" in scientific terms) according to the Diagnostic and Statistical Manual of Mental Disorders by the American Psychiatric Association and the International Statistical Classification of Diseases and Related Health Problems by the World Health Organization.
