sanvers + touch (4/?)
Sheith headcanon: Shiro is terrified to take his prosthetic off in front of Keith. Unfortunately that means wearing it for long hours at a time, and sometimes trough the night (big nono) which creates pain in his arm and shoulders. Keith notices one day and convinces him that he has nothing to be ashamed of. He helps Shiro take it off and proceeds to knead his aching muscles. Across his broad shoulders, down his bicep and forearm. Shiro slowly relaxes into Keiths gentle touch.
