Dragon Booty

Spike loved big butts and he could not lie. Although Spike was a dragon, he never found any of the typical attractive traits attributed to female dragons particularly appealing, because he was raised by ponies, so it was only natural that he might be more attracted to what ponies would consider attractive, besides it wasn't like inter-species relationships were unheard of.

However Spike's favorite part of a pony was the ass, or more specifically, a big, round, soft and jiggly ass. It was part of the reason why he had been infatuated with Rarity for such a long time, she had a very nice and filled out rump, sure some of their other other friends had bigger more beautiful backsides like Pinkie Pie or Applejack, but Spike never imagined himself as being compatible with either of them in a relationship sense. One thing he had noticed, was that of all the asses in all of Equestria, the ones who had the best, most perfect asses in the world were the princesses. There was no defining reason as to why, but for some reason every single princess, Twilight included, just had the most magnificent butts he had ever seen, he found it a struggle not to daydream whenever there were royal visits and accidentally just pop a boner or start drooling, it was nightmarish!

Spike couldn't help that he found big butts so sexy, it was just who he was, an insatiable dragon with an unquenchable thirst for ass and a sex drive that was cranked up to 11 24/7. Bedding Twilight was simply out of the question, Twilight was basically his mom, so unless she had some some sort of weird incest kink that she hadn't told him about there wasn't much going on there. Cadence was married, so unless the princess of love had a very open relationship, he couldn't imagine any shot of getting his claws on her big butt. As for the two rulers of Equestria? No chance, why would the rulers of the country ever entertain or indulge a dragon of all creatures in some sort of perverse fantasy? That wouldn't make any sense.
