Yes, there could be. Many fanfiction writers like to explore different scenarios, even ones that seem out of character like this. But often, they are written in a way that is more about exploring relationships and emotions rather than anything inappropriate.

Often, there could be a plotline where Gray is forced into a situation that makes it look like he's cheating. Say, an enemy of Fairy Tail frames him by creating false scenarios. Or it could be a situation where Gray is trying to protect Lucy from a greater danger by getting closer to someone else, but Lucy doesn't understand his intentions at first. There are also plotlines where Gray's past comes back to haunt him and his interactions with an old acquaintance seem like cheating to Lucy.
