Who could be the main character in a 'bloating boy belly fanfic'?

Well, it could be about a boy who eats a lot of strange foods at a magical feast and his belly starts bloating in a very exaggerated way. Maybe there are some fairies or magical creatures around him who are both amused and concerned about his bloated state.

Since I don't know the details of the 'belly gainer boy story', I can't say for sure who the main character is. It's probably a boy, as the title suggests.

Well, 'bloating fanfic' can be thought of as fanfiction that has gotten out of hand in terms of its length or content. Maybe the writer is trying too hard to expand on the original source material's world or characters. It could end up making the story feel cumbersome and less engaging. For example, if a fanfic about a certain movie character starts adding dozens of side characters and sub - plots that don't really add much to the main story, it becomes bloated.

An inventor could be the main character. While working on an experiment to create a new type of super - food that provides a huge amount of energy, he accidentally consumes some of it. This causes his belly to start expanding uncontrollably. He then has to use his inventive skills to find a way to reverse the effect while also dealing with the practical problems of having a large belly, like getting around his cluttered laboratory.

It could be a jealous rival of Bucky. Maybe this rival is envious of Bucky's popularity and when he sees Bucky's round belly, he uses it as an opportunity to mock and undermine him at every turn, becoming the main source of conflict in the fanfic.

The obvious main character would be the delivery boy himself. He could be a young guy just trying to make some money to support his family or pay for his studies.

One reason could be diet. If a boy consumes a lot of high - calorie foods like junk food and sugary drinks regularly without much exercise, he is likely to gain belly fat. For example, eating a lot of fried chicken and soda.

Sharon Carter could be in the fanfic. She could be the one who provides some medical or scientific insights into what's happening to Bucky. Maybe she has some knowledge of the experimental substances that might be related to Bucky's growing belly and tries to use her resources to help him.

Since I don't know the exact 'big belly hold story', I can't say for sure who the main character is. It could be an overweight man or woman.

Since I don't know the specific 'tight full belly story', I can't say who the main character is. It could be anyone from a child who ate too many sweets to an adult at a big feast.
