>Be Celestia.
>You're trotting down the hall towards your sister's room.
>She was late for breakfast and so was Anon, so you figured while you drank your morning tea you'd go see what was keeping her and if she saw Anon.
>Ever since Anon hit eighteen -both- of them had been acting weird.
>You swear she better have not have gotten a whorse like she said she was going to do on his birthday!
>”But Tia! He's officially a stallion! Not just that, a -royal- stallion!” She said looking at you as if you were crazy. “It is tradition that he mate with a citizen to continue the line! Whom better than a element of harmony?”
“Luna, my baby is -not- going to ‘mate' with -any- mare he doesn't love! Times have changed Luna, and if the papers somehow got word that the prince had sex with a mare outside of a herd or marriage they'd never let us live it down.”
>”But sister-" She starts but you won't hear any of it.
“Not buts. My son won't have sex with any mare-"
>She goes to say something.
“Or stallion!”
>She shuts her mouth.
“-that he doesn't love, and that's final!”
>You say stomping your hoof.
>Luna lowers her head and ears.
>Then suddenly perks up.
>”So you're saying if I find somepony whom Anon truly loves, he can mate?” She ask hopefully.
“Well, if they of them loved each other very much and have known each other for a very long time and were both okay with it. I suppose, yes they may ‘mate'.”
>Luna hops up with a flap of her wings in joy.
>”Merrily! Then I shall find a mare Anon cares for! I must be off now!” She says propelling herself through the air and out the door.
>Getting back to the present day you realize how she could have misinterpreted love and begin to gallop down the halls nearly knocking over a few guards on the way.
>You reach Anonymous’s door and calm yourself before quietly looking in to see…
>Nothing.
>You breathe a sigh of relief.
>Now you feel silly, Luna knows how love works, she's a full grown mare for your sake.
>You trot over to her room across the hall to check on her and see if she knows were Anon is.
>You open up the door and see…
>No she didn't.
>She wouldn't be stupid enough.
>In Luna's bed you see her and Anonymous both laying together with slight smiles on their faces.
>You quickly teleport Luna out of bed and into the hall.
>She wakes up quickly after falling to the ground.
>”Huh? Wha?” She says looking around.
“Don't you ‘Huh?’ me! What. Did. You. Do!”
>”What do you mean sister?” She ask looking confused.
“I -mean-, why is my -son- in -your- bed!”
>You say with venom in your tone.
>She sits up and thinks for a bit, before saying “Oh!” and shakes her head a bit.
>”Well sister, you told me to find somepony that Anon has known for very long and loves very much.”
“Mhmm.”
>”So I searched high and low for a maid, a guard, even your student Twilight, then I even asked your Secretary! Yet I found nopony that has known Anon a long time.”
>You're -so- going to question Inkwell.
>”But then it hit me, who better but one of us!”
>Anger fills you.
“So you screwed my son!? He's your nephew!”
>”No I did not ‘screw’ your son sister! We are not a barbarian!” She says looking offended.
>Oh thank-
>”We had sex. Not ‘screwed'.” She says looking proud.
“Luna, if you know what's good for you. You'll run.”
>You say placing down your coffee.
>She tilts her head.
>”Why's that sister?”
>Your horn begins to glow and shoot sparks everywhere where causing her to look scared.
“Because I'm about to make your thousand years on the moon look like a vacation!”
>With that you're both off!
 
>Be Anon.
>You pick up your mothers coffee and take a sip.
>”So. Did you really have sex with princess Luna?” One of your personal guards ask you as you watch them run down the hall.
“Nope.”
>He tilts his head and looks at you.
>”Then what'd you do?”
>You begin to explain it to him.
>You were laying in your bed when suddenly your aunt’s head pokes in.
>”Nephew, could you come to my room? I have something to show you.” She said before quickly dragging her back.
>So you did.
>As you entered the room you saw it was empty except for the light in the bathroom, so you thought she had to use the bathroom first.
>So you sat down on her bed to wait.
>Minutes later the bathroom light goes out and the door opens up.
>Black smoke poured out as a figure walked out behind it.
>You went to get up but some magic pushed you down.
>The smoke got closer and the figure became more visible.
>Soon you found yourself completely held down on the bed as Luna climbed up.
>The smoke cleared to reveal her but she was different.
>She wore lacey dark blue laundry, her eyes were not her own, but the cat like blue of Nightmare Moon, as were her sharp teeth.
“A-Aunt Luna, are you alright?”
>You asked, fearful she was turning back into the Nightmare.
>She placed a hoof on your lips silencing you.
>”Shh, dear nephew~ just be quite while Luna helps you~” She said her horn lighting up taking off her laundry.
“H-Help me?”
>You were scared.
>”Yes, help you. Rejoice, your princess Luna has decided to grace you by making you a Stallion~” She said in a sultry tone.
>You know she meant man but were scared to correct her.
>You always loved Luna, but not like this!
>But you knew there was no escape from her grasp.
“Auntie, don't do this. I love you!”
>She grins.
>”I love you too dear nephew, that's why I'm doing this.”
>You close your eyes and look away as you await the inevitable.
>But then you feel, bouncing?
>Not on you, but the bed.
>You open your eyes to see your aunt jumping on the bed slightly flapping her wings to give her momentum.
“Umm.”
>”Have ye came yet dear nephew?” She says still jumping.
>Gone is her sultry attitude, instead it's just… Luna.
>Does… does she not know what sex is?
>Not one to throw away a blessing you answer her.
“Yes auntie, I came.”
>”Huzza! The job is done, and in record time!” She says as she stops bouncing and lift's you up. “Well, I am quite tired nephew, so let us sleep in the ‘afterglow'" She says as she pulls back the covers of her bed and crawls in before placing you down and covering you both.
>You smile at her innocence.
“Sure auntie. Let's go to sleep.”
>Finished explaining you look at your guard.
>He looks like he's about to lose it, and soon does laughing.
>After a bit he regains himself and calms down.
>”S-So, you gonna go save your aunt?” He ask.
“Nah not yet.”
>You say sipping your mother's coffee.
“Besides, they both need the workout, and a couple laps around the castle never hurt anyone.”
>He giggles a bit.
“No telling anyone about this.”
>”Wouldn't dream of it."
