It could mean that in a Vampireluv, Sess, and Kag fanfiction, the concept of time is passing quickly. Maybe the story is about their adventures and how time doesn't wait for them as they face various challenges or experiences.
The theme can be incorporated by having time - sensitive quests or missions for Sess and Kag. For instance, they have only a short amount of time to gather magical artifacts to save their world. Every second counts, and the sense of urgency due to the fleeting time drives the plot.
I'm not sure specifically as I haven't read it. It could be about a child's perspective or experience within the context of the Ky Sess Kag fanfiction universe.
One idea could be a story where Sess and Kag are characters in a world where time is rapidly disappearing. They have to race against time to save their realm or relationship. For example, they might find that with each passing moment, parts of their memories together are fading, and they must find a way to stop this time - based decay.
Perhaps there are countdowns in the story. For instance, a prophecy states that a certain event will occur in a set amount of time, and as the days or hours tick by, the characters feel the pressure. Sess, Kag, and the vampireluv character might be scrambling to prepare, and we can see how time is fleeting through their rushed actions and worried conversations.
I'm afraid I can't recommend similar ones as I don't have enough information about 'a child's voice by ky sess kag fanfiction' to determine what makes it unique and then find similar works.
