It depends on how it's written. If it's just a sweet, innocent kiss within the context of a developing relationship in the fanfiction, it could be considered appropriate for young audiences with parental guidance. However, if there are other more mature themes associated with it, then it might not be.
Maybe in the fanfiction, the kiss was a result of a dare. After the kiss, Sam realizes she has deeper feelings for Freddie than she thought. So she starts to act differently around him, like being nicer and more protective. Freddie, on the other hand, is really confused about his own feelings and they both have to figure things out while still being part of the iCarly crew.
The popularity might stem from the fact that it shows a significant development in their relationship. Fans of the characters are often interested in seeing their relationship progress, and a kiss in bed can be a very intimate and exciting moment for them to read about.
Well, perhaps in the fanfiction, the kiss occurs after a big argument between Freddie and Sam. They are both so frustrated with each other but then suddenly, in the heat of the moment, they kiss. This could then lead to a period of confusion as they try to figure out what it means for their friendship and their relationships with Carly.
One common theme is the build - up of their relationship. It often shows how they've been secretly attracted to each other for a long time and how the kiss is the culmination of all those unspoken feelings.
If other characters in the 'iCarly' universe find out about the kiss, like Spencer, he might tease them a lot. But on a more serious note, it could also change how the group dynamics work. For example, if Gibby finds out, he might be confused and not know how to act around them anymore. And this could lead to some really interesting plot developments in the fanfiction as they all try to adjust to this new situation.
