They are not very common. In real life, it's a private and embarrassing matter for anyone, including girls. While there might be some rare instances due to various reasons like a sudden medical emergency or being in a really difficult situation where access to a toilet is impossible for a long time. But overall, it's not something we hear about often in regular stories.
One reason could be that they are in a situation where there is no access to a toilet for a long time. For example, if they are stuck in traffic or in a long line. Another reason might be that they are really scared or nervous, which can sometimes cause loss of bladder control in stories.
There are many great aspects of the gay community like their contributions to fashion, music, and social awareness, and we should shift our attention to those instead of seeking such unseemly stories.
Once upon a time, there was a little girl named Lily. She was so excited during a long car trip that she didn't want to stop to use the bathroom. She kept holding it in until finally, just as they were pulling into a rest stop, she couldn't hold it anymore and had a little accident in her pants. It was embarrassing for her, but her parents comforted her and told her it was okay as it can happen to anyone.
In general, while there could potentially be rare cases where a boy might do this for some very strange or extreme reason, the vast majority of such stories are likely fabricated for the purpose of entertainment or to teach a lesson in a story. For instance, a story might use this idea to show the consequences of misbehaving or not following proper social norms.
I don't really have any specific 'pissing girls outdoors stories' to share. It's not a very common or appropriate topic for general storytelling in a positive sense. However, if we consider the idea of girls being outdoors and facing challenges related to finding restrooms or such in a more light - hearted and appropriate way, there could be some humorous anecdotes. For example, a girl on a long hike who has to be very creative to find a private spot.
One reason could be that she was too engaged in an activity and didn't want to take a break to use the bathroom, like the girl at the fair who was having too much fun. Another reason might be nervousness, similar to the girl in the school play who was so nervous she forgot about using the bathroom.
Yoga pants are very stretchy, which allows girls to move freely during physical activities like yoga or running. For example, if a girl is doing a deep stretch in yoga, the yoga pants won't restrict her movement.
Such stories are highly inappropriate and can be considered vulgar and offensive. They have no positive implications and go against common decency and moral standards.
