It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
The 'blimp boy story' could be a fictional tale that combines elements of a boy's life with the unique presence of a blimp. It might be set in a particular time period, say the early days of air travel when blimps were more prominent. The boy could be an orphan who finds solace in an old, abandoned blimp. He starts to fix it up and in the process, he meets various characters who help him or try to stop him. As he works on the blimp, he might learn valuable life lessons about perseverance, friendship, and following his dreams.
Once there was a blimp flying over a big city. The pilot of the blimp decided to play a prank. He made the blimp do a series of crazy loops and dives. People on the ground were shocked at first, but then they started to laugh as they realized it was all in good fun. The blimp became an instant source of entertainment for the whole city that day.
Once upon a time, there was a man who suddenly found himself transformed into a human blimp. He floated above the city, looking down at the tiny buildings and people. He could control his direction by simply thinking about where he wanted to go. As he drifted over the park, children pointed up at him in amazement, thinking he was some sort of strange new balloon. He enjoyed the feeling of the wind against his blimp - like body and decided to explore the countryside. There, he floated over fields of flowers and grazing cows, having a unique view of the world that no one else had ever experienced.
As far as I know, there are no well - known sexy blimp audio stories. Sexy themes are more common in other types of stories like romance novels or movies, but when it comes to blimp - related audio stories, they are usually more about adventure, history, or science - fiction aspects of blimps rather than being sexy.
Since I don't know the exact 'blimp boy story', the main character is likely the boy. There might also be other characters like the people who operate the blimp, or his friends and family who are involved in some way with his blimp - related experiences.
There was a small-town fair and a blimp was invited to be part of the attractions. The blimp had some technical glitches and instead of flying smoothly, it would bob up and down erratically. The fairgoers found this so funny that they started to place bets on whether the blimp would go up or down next. The blimp operator, though a bit embarrassed at first, soon joined in on the fun and made the best of the situation.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
It could mean that a person who is a fan of 'Attack on Titan' (AOT) is reading or watching fan - created fictional works related to AOT. Maybe they are interested in seeing different interpretations or storylines that fans have come up with.
