Sure. There could be a story where a stranger in the airplane bathroom lent you some much - needed toiletries when you realized you forgot yours. It's a simple act of kindness that has nothing to do with inappropriate topics.
One horror story is about a passenger finding a big spider on the wall of the airplane bathroom. It was huge and hairy, and the person was terrified and didn't know what to do. They were afraid it might jump on them while they were using the facilities.
Well, privacy issues can be common too. Sometimes people might think there are peepholes or they hear strange noises from outside while they're in the bathroom. Also, the small space can contribute to horror. If you're a bit claustrophobic, being in that tiny airplane bathroom when something goes wrong, like the light flickering, can be really scary. It feels like you're trapped in a small box with potential problems all around you.
A proper encounter could be when a stranger asks if you are okay if they hear some strange noises from your side of the bathroom, out of concern. Also, if someone needs to use the bathroom urgently and you let them go first in a friendly way.
It's not appropriate. Fanfic should generally be family - friendly or at least abide by certain ethical boundaries. Such sexual content can make many readers uncomfortable and may also violate the rules of platforms where fanfic is shared.
Sharing such stories is inappropriate as they involve private and often inappropriate sexual content. We should focus on positive, respectful and family - friendly topics.
Sharing public bathroom sex stories is completely unacceptable. It goes against the norms of decency and propriety. We should respect public spaces and keep them free from any form of inappropriate sexual content.
One alternative is to write about the architecture or design of bathrooms in a fictional world. You can describe how the tiles are arranged, the unique features of the fixtures, and how the characters interact with the space in a non - sexual way.
