Ass to OTHER mouth. Occurs during a threesome with two girls and one guy. Fuck her in the ass and then blow your load in her friend's mouth.

Porn or Hardcore Sex, Man pulls penis out depths of a woman's ass and immediately puts in ANOTHER woman's mouth. A degrading but satisfying act.
Bro, did you go ATOM last night?

Similar to regular ass to mouth ATM, although this would be normal under orgy situations, ATOM or A.T.O.M. refers to fucking the first girl in the ass then hooking up with a different girl a short time after and receiving a blowjob first.
