For years, Twilight Sparkle and Applejack have used every trick they can think of to seduce their brothers... with unsexy results. With Big Mac and Shining Armour now both happily married, the two friends decide to try one last time. They jump into a parallel universe, where they can finally hook up with the forbidden stallions they lust after.

Of course, the ponies in parallel universes won’t be quite the same as the ones they know... but that just means it’s not technically incest, right?

My entry for the Sibling's Day Incest Contest: a naughty sex comedy featuring consenting adults and an ending of pure smut.
