My first girlfriend was a loose-legged bitch known locally as the "communal sex urinal"...

My first girlfriend was supposed to be the ideal girlfriend, pure, quiet, considerate and kind... One day, she left her phone behind. I looked at her phone screen on a whim. She couldn't be lying. A chat group called "public toilet" appeared on her phone. And a picture of a woman who looked like her, dressed in a lewd manner. I told myself that it was some kind of prank or spam chat.
