A specific facial
expression caused by the insertion of a penis or another firm and long object. Rumours says that the anal face of a person is as unique as their own finger prints, if not even more.
Many people of the younger
generation have agreed that the decision whether they are to keep their
girlfriend or not is determined by their anal face.
Science has shown that there is in fact a certain muscle that gets tingled when insertion happens. This muscle flexes and the anal face appears. The strength of this muscle differs from person to person.
Not only women posses the anal face.
