I've been looking for this oneshot for AGES. I remember the art being absolutely GORGEOUS. It wasn't a doujin, it was just random characters they created. In this one there was a prince who had to go stay at this chubby dude's palace in order to create a deal to help his country. Throughout the whole thing the chubby dude constantly fucked him and by the end of it the prince chose to stay there. His consort constantly tried to get him to go back to his kingdom but in the end he chose to stay with the ugly guy. If you could help me find it that would be very appreciated!! ヾ(☆▽☆)
