Ed didn't like people touching his automail. The only person he let touch it was Winry. Mainly, because she was his mechanic. Sure, other people saw glimpses of the automail, but it was usually just the arm. A select few had seen his leg. It was different for each person due to the unique situation.
Winry had seen it while she repaired his automail.
Al had seen it in quite a few different situations. When Winry was repairing his automail or when he had been cleaning it.
Roy had…well that situation was unique if anything. Ed thought with a slight blush.
Sure, Roy had seen the automail on many different occasions but, Ed never liked him touching it. Especially when his fingers pressed against the catch. It made him nervous.
Ed didn't like anyone touching the catch on the automail. It was one thing seeing and touching the automail, a totally different one seeing and touching the catch.
With the catch, all it took was one simple flick of the wrist and he was helpless. Ed didn't really like the feeling.
Sometimes, Roy's fingers would brush the catch. Ed would be pulled out of the heat of the moment and try to move away from Roy. There would be a moment of silence and Roy would move his hands away from the catch and apologize. Ed was sure his lover had not meant to touch the catch.
Roy knew where the catch was because he had removed the automail a couple times. When Ed had busted the automail and had to removed it for when Winry could come to Central.
Ed knew when Winry came to see him that Roy would be nowhere in sight. Ed knew he felt guilty about Winry's parents. Roy would normally reappear when Winry had gone to spend the night wherever she was staying or to see Al.
Roy was one of the few that knew where the catch was on his automail. The man only knew because he had to remove the automail a couple times. He never touched the catch without Ed's permission, most of the time anyway. Sometimes Roy touched it without permission but it was mostly accidentally.
That was what Ed like best about Roy. It wasn't his good looks or his charm. It was the way he didn't go against Ed's wishes about his automail.
