TRIGGERS: Futa, Cum Inflation, Endless Orgasms

Lightning Dust and Rainbow Dash decide to finally settle the score in who the best pegasus is in all of Equestria. Somehow, the contest becomes who can rut the other mare the best. Unfortunately for Lightning Dust, she has no idea what exactly Rainbow is packing. This could only end well.

Written for a friend who doesn't like reading long fics (anything over 1k words) at all. The challenge was to make it erotic as possible in the fewest amount of words. Hopefully it's decent. I really tried to stay within the requirements, but to be honest, I could probably do better if I had fewer restrictions. It was fun writing anyways.
