It depends on the context and the relationship between the couple. In a very private, trusting, and consensual relationship, sharing such stories might be a form of sexual communication. However, it should always be within the boundaries of respect and legality.
I'm not sure specifically what the 'kinky girl banding story' is about as the term 'kinky' can have various meanings and without more context it's hard to define. It could potentially be about a group of girls in a band with some unique or off - beat story.
No, it's not okay. We live in a society that values respect and dignity. These types of stories often reduce individuals to mere sexual objects and can also perpetuate harmful stereotypes about different cultures and races.
Often, kinky girl stories involve a girl with an unconventional interest. For instance, a girl who is fascinated by ancient languages and spends hours deciphering hieroglyphics or old runes.
Well, without more context, it's hard to say precisely. 'Kinky' often implies something a bit edgy or different in terms of behavior or preference. Maybe the 'elastrator' is some sort of object or device and the girl is using it in a teasing way within the story. It could be a very specific or niche story within a certain subculture or just a made - up, creative concept.
