Analysis of information sources in references of the Wikipedia article "Siber seks" in Turkish language version.
The goal of mud sex is the same as the goal of regular sex (without the babies): to bond temporarily in a way that is physically and emotionally satisfying. To do so, two people will exchange messages so as to lead one another into a high level of sexual arousal, culminating in a well-defined resolution.
To be blunt, most mud sex is also accompanied by the people sexually gratifying themselves in real life at the same time.
