I'm not sure specifically what a 'first time cum swallow story' would be in a general sense. It could potentially refer to a very personal and private sexual experience which is inappropriate to discuss in detail.

I'm not entirely sure what a specific 'first time swallow gum story' would be. But generally, it could be about a person's first experience swallowing gum. Maybe it was an accidental swallow as a child when they were just learning about chewing gum and didn't know they shouldn't swallow it. It could be a bit scary at first, but usually, it passes through the digestive system without too much trouble.
There are multiple negative consequences. Firstly, it can severely damage her innocence. A little sister should be in a pure environment, and erotic stories will taint that.

There could also be predators that pose a threat to the little swallow, such as hawks or snakes, which would also be part of the character list in the story.
Loving your sister in a proper, family - affectionate way is normal. But the term 'cum' is inappropriate and vulgar in this context.
