🎶And sooooooohooohoooh I ask the suuun to staahaayyy…. But knweeeeeeeeeeeew I’d let her gooo somedaayaayaayaayaaayyyaayyayyy, Some daaay🎶

Luna: SIIIIISTEERRRRR!
Celestia: Zzzz…..*pop* Huh?… Yes Luna, What is it?
Luna: Can you help me apply sunscreen on my back? I can’t reach it!
Celestia: I will do it in a minute!
Luna: Can you please do it now? I think it feels like it’s getting sunburned already!
Celestia: Ugh! Okay, okay! I’m coming!
Luna: Oh wait, nearly forgot! It’s my time to put on the music! *Beep*

🎶Luna tu! Quanti sono i canti che risuooonano! Desideri che attraverso i SEEECOLII! Han solcato il cielo per raggiuuungerti🎶

Celestia: HEEEY!! I was still listening to that!
Luna: You were listening to that for almost an hour! Besides, we agreed to switch who is in charge of the music every half hour.
Celestia: Then it doesn’t have to be EXACTLY half an hour!! Let me at least mentally prepare for those operas of yours!
Luna: Heh, being dozed off is convincing enough to me for you to be mentally prepared!
Celestia: I! WAS! NOT! SLEEPING!! I was relaxing! And thinking if I didn’t forget any tasks in Canterlot. I don’t want to burden Twilight with more than she already has on her plate!
Luna: I guess you were only thinking about which sun song to put on next.
Celestia: OKAY!! LISTEN! Do you want me to put sunscreen on your back, or do you want to argue over the music?
Luna: Hoh oh ohkay okay I’ll stop pulling your leg! Wow sis, you are still really stressed! Twilight will do just fine, believe me! It was a good idea of yours to go on vacation. It feels good to finally be awake at the same time with everypony else without the urge to collapse on the ground. I needed this, you as well!
Celestia: *Sigh* you’re right, I’m still a bit fired up. Twilight will manage that is true. Now, where do you still need sunscreen?
Luna: Actually, I haven’t exactly started yet.
Celestia: …All right! Next time you apply some yourself before asking me, but now I’ll give you the princess spa treatment.
Luna: Oooh! The princess spa treatment! Does that include a happy ending?
Celestia: Yes, I’ll make you a cocktail afterwards.
Luna: YES!!
Celestia: Now that I think about it, I forgot that you can see if someone is asleep or not. Was I sleeping al this time?
Luna: Obviously!

I normally don’t want to talk a lot about myself when I upload pictures but I’ve never puzzled as much with fixing pictures as with this one. Hands are still difficult to draw right but I’m getting better and faster! I’ll include the original AI output here so you can switch back and forth to see the differences.

In case you want to know the songs:

The Sun, Secret night gang
