After a double date in Canterlot, Gilda and Rainbow Dash are walking home with their human boyfriends. But even on a friendly outing, old rivalries still simmer... and the fliers find themselves unable to agree: which of their boyfriends has the best ass?

For a couple of muscular well-hung futas, it's an important question... and after they almost come to blows, they come up with a better idea. How about they prove to each other which ass is best, with a night of hard pounding and boytoy-swapping?

(Rainbow Dash and her boyfriend are from Beneath Her Wings by Problem Grippin. Gilda and her boyfriend are from Gilda the Girlfriend, by me.)
