My first girlfriend was a loose-legged bitch known locally as the "communal sex urinal"...[2025]

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.
