You come home after a very long day, completely exhausted and throw yourself onto the bed.
Loki looks up from the book he is reading. "Oh dear, is she dead?"
"Only internally", you groan.
A smile flashes over his face. He leans down to you and his hair tickles your neck. "You know, I can make you feel better internally ... with my fingers ... caressing these walls ... or my tongue ... or the other thing that made you scream last night."
