Teloch asked: If one person wakes up before the others, how do they wake up the rest? Fluffy and smutty options.
Both Zuko and Ty Lee will just stare at their partners lovingly if they wake up first, enjoying the warm feeling they get at seeing their loved ones sleeping so peacefully. The difference is Zuko will just gently snuggle against the one that is closest to him, while Ty Lee with try to give a group hug to her lovers and accidentally wake them up because she was too excited.
However, when she really wants to show how much she loves them, Ty Lee will quietly sneak to the kitchen, make them an amazing breakfast and have them all eat it in bed. Mai can either just let them all sleep for as long as they want while she starts taking care of their responsibilities of the day for them, or she'll gently kiss and caress them. Azula is also a fan of the whole "good morning kiss" thing, but one morning she was just way too "loving" and it led to the smutty way they all wake each other up: the one who woke up first will go down on one of their sleeping partners, and after they're awake they'll both wake the other two up the same way. The only problem with this is that they then don't leave the bedroom for a looooong time.
