Twilight Sparkle, Shining Armor, and their Dad have incestuous sex

The Cakes have lovely incestuous sex, starting with the Twins

Six stallions have an orgy organized by Spike

Fluttershy pegs Big Macintosh

Applejack has sex with Bloomberg

Princess Celestia clops while two male Guards have sex

Soarin' has sex with a pie

Hoity Toity x Big Macintosh have plenty of gay sex

Twist x Gummy Silly Shipfic

An erotic poem describing an encounter between Zecora and Twilight Sparkle
