Using the term 'pussy' in this context is vulgar and inappropriate. We should focus on positive and respectful topics in literature, such as stories about strong female characters achieving their dreams.
One interesting pussy girl story could be about a pussy girl who was very adventurous. She loved exploring new places in the forest near her home. Every day she would find a new nook or cranny and make it her own little discovery place. She might meet different animals there and have unique interactions with them, like befriending a little squirrel that would come to her for nuts she found.
There are no girl pussy tickling stories in children's literature. Children's books are designed to promote values like friendship, kindness, and learning, and such inappropriate themes have no place in it.
I have no idea if it's popular as I've not heard of this story before. There are so many stories out there that it's difficult to determine the popularity of one without more information.
I'm not sure specifically what that story is about as the name is rather unclear and could potentially refer to many different fictional or real - life accounts. It might be a story related to a sorority girl's experience in college, but without more context, it's hard to say.
Rather than focusing on such potentially offensive phrases for stories, it's better to explore more positive and respectful aspects of BDSM, like the importance of communication and safety within the BDSM community.
If your girlfriend likes cat stories (assuming 'pussy' means cat here), you could start by finding some really interesting cat - related books or documentaries for her. For example, there are books like 'The Cat Who Saved Books' which has a heartwarming story about a cat. You could also share with her any cute cat videos you come across on the internet.
