After finding out about Applejack's Hearths Warming escapade with Limestone, Rainbow refuses to stand for someone else having some of her Apple and she so challenges Limestone to see who can REALLY pleasure Applejack the more and is the better dom. The stakes, the winner is Applejack's official girlfriend and whatever else the winner wants.
Limestone is game... why is she smirking?
Maybe this wasn't such a good idea after all.

Note: While the Non-consensual tag is selected, there is no actual rape... just the aftermath of poorly worded statements.
