Rainbow Dash can be said to be many things but refined has never been one of them. While others would call her self-centred, you've always known there's a heart of gold beating in that chest. Even if she does tend to take charge, it's only because you trust her enough not to abuse that. So when you find out there's more to the mare than you previously thought, are you truly willing to submit yourself to her and trust she'll know what's best?

Yes, more shameless clop inspired by an image by Kevinsano. Second-person, "you" and futa-Rainbow Dash. The focus here is on some pretty rough sex so if that's not to your liking you may want to avoid it.
