Anal Echo

As you perform anal sex, air seeps into your counterparts anal cavity and is stored there until finished. After finishing with this endeavor, your counter part stands up and proceeds to fart; air escaping the ass.

I was pounding this girl in the ass from behind, as soon as we were finished I pulled out and heard a few anal echoes.

A highly-embarrassing (or highly-AMUSING, depending on who you talk to, or on whether "high-brow" or "low-brow" company happens to be present at the time) phenomenon whereby your butt-hole decides to do its Robert Perry impersonation --- i.e., you fart at the same time as you perform some other bodily-function "upstairs", such as coughing, sneezing, wheezing, gagging, etc. Extra caution/concentration/awareness is often in order in an instance such as this, since it can be prime circumstances for an incident of orifice-outflow overload.

Why is it that any degree of crude disgustingness regarding unfortunate nasal/oral occurrences is always tolerantly allowed for, but people get all grossed out if there are any accompanying anal-echos??
