The aftermath of [[implied fellatio]] or [[after fellatio]], when the [[fellatio]] act has almost certainly occurred, yet has never been directly spotted. This is usually due to [[out-of-frame censoring]], or a character [[facing away]] from the viewer until it's too late to be sure what actually happened, in spite of a few obvious hints.

Most often there is only one partner left alone and/or who's still carrying the last remaining visual cues (Ex: [[disheveled]], [[sunken cheeks]], unconvincingly acting like nothing happened, the presence of [[saliva on penis]]/[[stray pubic hair]] around the mouth, etc.)

It's often used with [[cum in mouth]] although this alone could simply indicate a [[facial]] without any penetration.
