I don't remember the title of this story, but I remember the basic plot. The story itself is relatively short (shouldn't be longer than a few thousand words) and from Dash's point of view. It's either EQG or Human, but I'm more confident it's EQG.

The plot is it's basically a monologue during lunchtime about how Applejack is just perfect. Rainbow can't help but agonize over every detail about Applejack in the most simpy/lustful way possible (in one instance, she envies the chair that Applejack has spun around and is straddling). Her monologue ends when the bell rings and jolts her 'awake' to see that everyone is staring at her because she actually said all that out loud and to Applejack's face instead of just in her mind like she thought. Embarrassed, she runs out of the cafeteria and tries to drive away on her motorcycle, but Applejack stops her and asks her if she means it. I think they share a kiss, but I'm not sure.

Any help would be greatly appreciated!
