Ass to mouth is a colloquial term for the removal of the penis from the passive partner's anus followed by the immediate insertion of the penis into the passive partner's or another partner's mouth.

Alternate terminology

It is also known as A2M, ATM, or Arse-to-Mouth. Ass to mouth generally excludes cleaning the penis or other object after its removal from the anus and before its insertion into the mouth for the sake of increased sexual excitement. "Ass to other girl's mouth," abbreviated as A2OGM or ATOGM, specifically describes the variant of the act where the penis is moved from one partner's anus to a different partner's mouth. The term has been used since at least January 1995 and clearly defined since at least August 1996. Despite its health risks it is prevalent in pornographic films.

Prevalence in pornographic videos

Ass to mouth became something of a fad around 2003 or 2004 in Americanpornographic videos
The release of a Heatwave/Horizon film simply titled "Ass to Mouth" in 2000 coincided with a growing focus on this act in mainstream pornography. Heatwave/Horizon debuted a second similar series, "A.T.M. Girls" later the same year. The act billed prominently in multiple films and led to the debut of several new series focused specifically on the act, such as "A2M" (2003, Anabolic) and "ATM Machine" (2003, Digital Sin). The original "Ass to Mouth" series from Heatwave/Horizon was suspended in 2005 after "Ass to Mouth #15", but the decline in niche films reflects the fact that this act has become part of the standard repertoire. Among the more prominent porn actors and actresses, Sam Beile-Fisher, Flower Tucci, Sasha Grey, Olivia O'Lovely, Tory Lane, Shy Love, Brianna Banks, Tiffany Mynx, Jenna Haze, Kinzie Kenner, Lauren Phoenix, Taylor Rain, Aurora Snow, and Jessica Darlin are also known for performing this fetish in their adult movies.

Health risks

The health risks of ass-to-mouth include the risks of both oral sex and anal-oral contact (siehe auch ZA und AV). Unprotected oral-genital contact involves the risk of contracting sexually transmitted diseases, such as genital herpes or intestinal parasites. The recipient of ass-to-mouth is also at risk of infection by Hepatitis A. It is unknown whether thoroughly washing the anal area and applying an enema results in reduced risk of disease. Porn-industry performers often use enemas prior to filming anal sex sequences; however, the purpose is to eliminate the possibility of any fecal matter appearing on film, rather than disease prevention.
