About This File
Personally I prefer my slaves to keep their hands behind their heads, but I couldn't find a mod to make it possible in a simple and efficient way. So I created one. This mod simply adds one arm offset animation which you can play by either typing in the console:
player.sae HandsBehindHead # Of course can be any actor.
or from Papyrus:
Debug.SendAnimationEvent(someActor, "HandsBehindHead")
Because it's an arm offset animation it will be injected into currect actor action like standing, walking or running. In simple words the actor should keep his hands behind his head all the time while standing or moving. To stop you can use "OffsetStop" with above methods.
In general this mod is rather a tool for my future mods, but I'm uploading it anyway, maybe it will be useful for someone. Use it as you wish.
