Breeding Royals in the Land of Ooo by Atomsk_the_Pirate_King, Twilight_Master_Emerald

Summary
In a nutshell, what if the Princess of the Goblin Kingdom, 20ish years past the Canon end of Adventure time, got kicked out from being too eager to dominate her people being a natural futa with Golem like Stamina thanks to her being Whisper Dan's daughter... and she dominated many in kinky ways and as a result her mother kicks her out for some time to run damage control for possible birth related reasons and this spirals into a sex filled adventure for the Futanari Goblin hybrid princess... enough said this is a VERY kink heavy story with bodies with large portions for most of the ladies here, Futanari, and much more.
Requested by Brightblight.
