There are a lot of fake wannabes on here but also some serious ones too, you just need to judge them by their comments and photos.
For instance any idiot can take a photo of themselves fucking their partner with time frame cameras or timed cameras on phones, but if the images are in different positions then that's a sure sign of the presence of another person. If she is holding 2 cocks again VERY sure sign of being shared. These are 3 of a gf I shared prolifically, notice the various angles the camera was shot from
