Hotch- Due to having to keep up a professional appearance,there isn't much to how you sit. You often just sit beside him with you hand in his.
Rossi- Just like hotch expect you have your head on his shoulder with his head on yours. (Sorry couldn't think of anything for him)
Reid- You sit beside him with your legs draped over his. He often will trace shapes on your legs.
Morgan- You just plain sit on his lap with his arms wrapped around your waist.
