I'm Your Stud [Centaur!USUK Fan Fiction]

This is a USUK fan fiction series with the characters as centaurs who live in Centalia. Centalia is a world where centaurs dwell. Some centaurs represent nations and dominate sections of land that are named after them. Warning: there will be hardcore yaoi scenes in some of the parts! I will be drawing all the images for this series. Anyways, here's the description:
Arthur Kirkland had returned to see Alfred F. Jones for the first time in years. Last time Arthur had seen Alfred was when Alfred was just a young colt, so he was very surprised to find that Alfred had already grown up into a stallion. Now that Alfred is an adult, both his and Arthur's feelings for one another develop into romantic ones. On the night of their reunion, they both decide to confess their feelings for each other.
