That's an interesting title.
Hmm...So, the protagonist basically stole her from the horse right when it was about to get laid? So basically he NTR'd the horse? Interesting development. Also, damn, just one night of googling and the conclusion she drew of how to deal with sexual desire is sex with a horse, conveniently ignoring the nearby young man with feelings for her? The internet is a scary place indeed. But hey, considering it afforded him an opportunity to get closer to her, it was a force for good this time.
That ending though. So he reaffirms his feelings for her, and now she mentions wanting to try plenty of things...I'm sure there shouldn't be a problem with her wearing the pants in the relationship.
