Original Description:
 
Despite becoming a workhorse stallion like his boyfriend, Rarity/Elusive never lost their interest in clothing and design. Sure, he was wearing a straw hat and overalls now, but he made them fashionable and striking (plus, the overalls got to let him show off his muscles a fair bit). Applejack’s clothes though? Not as impressive or complimented how handsome he was.
 
One day after work, Elusive had enough. He told Applejack he would be designing him a brand-new wardrobe. The stud was incredulous and had no real interest. As long as his clothes fit, didn’t hinder his work, and let him show off a bit, he was fine. However, Elusive insisted and pushed.
 
Applejack eventually proposed a wager. Beat the farm stud at a little arm-wrestling and Elusive could do whatever he wanted. It would be a cinch after all. While Elusive was certainly big and buff, Applejack spent all his life doing hard farm work before and after the cider. He had the muscles, strength, and experience to win.
 
Or did he?
