Girlfriend Poop Accident

My super hot girlfriend (a mix of Philippine and Austrian genes) really shit herself as an adult after a barbecue in the park last week. She is 27 years old and in our 3-year-relationship she seemed to have good anal control until this happened last weekend. A friend of hers celebrated his birthday in the park and my girlfriend obviously got the urge to poop after a while. However, as it was past 9 pm the park bathrooms were closed already and I guess she did not want to go in the bushes. It then took us some time to say goodbye to everybody as they did not understand why we wanted to leave already. We then walked through the park and took the subway to her place, but she did not make it and started pooping in her thong when we were still on the subway, right before her stop....honestly, the smell was super disgusting. And once we got to her place and as soon as she sat on the toilet, she had the biggest poop explosion that I have ever heard from any female human being
