I can tell who is a very easily.
The fourth one is definently the one who has had many dicks inside her. I can tell by her face. Her lips have turned into dick sucking lips. Her lips are not even. Sucking so many dicks makes your jaw looser and she has a loose jaw.
The last one looks like the one who hasn't had more than 1 sexual partner. She has the miskeen face. She looks innocent.
