Ass to Mouth's arcane 2nd definition:
when one is contacted by one means and replies by another.

Some believe it's a little rude, but sometimes there's little alternative.
You text me.
I call you and say, "Sorry to go ass to mouth, but I'm in the car and I don't want to die."

Doing ass to mouth sex is something only a complete whore will attempt and enjoy. She lets her man pound her ass in any position he wants then begs him to pull out and slide his cock into her mouth so she can taste her own ass, often repeating this several times. After he cums deep in her asshole she will suck all the cum and juice off his cock.
Kathy loves performing ass to mouth sex. She was 17 the first time a guy made her do it and shes been addicted ever since. Over the last 30+ years shes done it hundreds of times for hundreds of different men. "I dont care whos cock is pumping my dirty ass, I love to beg him to put in my mouth so i can taste it" she says. "I always rub my wet shaved pussy while im sucking him then i beg him to fuck my tight ass some more and tell him how good it tastes."

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.
