Nicol Vice - The fire brigade

Nicol is walking in the park and watching the training of the local fire brigade. Seeing all those hoses and water makes her have to pee. She stands up and starts searching for a suitable bush. There are plenty of people everywhere and Nicol is really shy (not only in this story but even in her real life!) so she hurries to a porta potty which is located near one of the park exists. After a long way she finally opens the door... just to find out what a disgusting place it is. NO WAY she could pee there. But where will she go...?
