Sun X Moon AU Oneshots

Siren AU- Sailor Sun x Siren Moon

Moon's pov:

It was another boring day. I waited for my next victim to come with their crew so I could take them away. I waited in my rocky perch with an easy view of the sea. Seeing a ship coming this direction. There surprisingly wasn't a crew by the looks of it. Just a captain on a small boat.

I dove back in the water, making a splash as I did so. I saw the young sailor seem to freeze and look around in confusion. He didn't seem scared like most would in this area... How adorable~ I started singing my usual songs to make him listen to me. He was so cute~ Perhaps I could keep him~

I watched as he seemed to fall under my spell, looking everywhere seeming dazed. I continued to sing to him, approaching his boat. He covered his face, seeming nervous, "W-who's there!?"

I peaked from the water, looking to him and seeing his cute face covered by his hands. I snickered and stopped singing as I jumped into the boat with him, "That would be me~"

He started to uncover his face hesitantly but froze as he saw my face. I smiled and hummed as I examined his face, "Aren't you a cutie~ Maybe I'll keep you a little longer~"

He blushed, uncovering his face and blinked to me, "K-keep me?.. What does t-that mean?..."

I smirked and gently held his chin, "Do you wanna find out pretty boy?~"

He blushed more at what I said which only made me smile wider, "Oh?~ Do you like being called that?~ A pretty boy?~"

He smiled shyly, "M-maybe..? B-but why?... I... Feel funny...~"

I caressed his face gently, "Hmmm..~ Don't worry about that~ Just follow me~"

I pulled back and dove in the water, like the others before he followed me into the water. The only difference was I would let him live, I swam to him before he could breathe any water, kissing his lips and holding his nose since I had a mouth full of air so he could breathe. I pushed the air in and out of him, helping him breathe. He struggled slightly but stopped squirming when he realized I was helping him breathe, I swam down and into my cave.

When I finally got us both to the air pocket and let him go from the kiss, licking my lips, "Mmmm..~ Welcome to my humble abode~"

He panted slightly and looked to me, shaking his head slightly, "A-ahh..~ W-what was that about?.. I-I never k-kissed anyone before.."

I tilted my head, "Really?~ I'm your first?~"

He blushed brightly, "M-maybe... B-BUT WHY DID YOU K-KISS ME!?-"

I put my finger to his lip making him blush more, "Would you rather learn to breathe water Sunshine?..~"

He froze, "....N-no... It's just... I-I don't even know your n-name.... O-or why I'm here..."

Chuckled at his statement, "That's fair... But I'll only tell you if you say yours first~"

Sun's pov:

I was in some kind of cave this mysterious moon themed merman brought me too. He acted so strangely but I wanted to know his name! The only way I could is by saying my name. That seems easy enough.... But why?

I decided I would get more information before saying anything, "W-why should I say?... You brought me here... A-and have no clue why I'm here... I understand not saying your name but a-at least tell me why you brought me here please...."

He leaned back and swam over to a bit of land in the underwater cave. He crawled up and shook himself dry from water. I watched in awe as he got legs after drying himself, he had star covered pants and shoes similar to my own. I blushed as he waved me to come join him, "I prefer people not see my sea legs..~ But I suppose you have good reason for your suspicions~"

I nod and he sighed, "Fine... but you still gotta tell me your name~ Deal?~"

"F-fine.."

He smirked with a sharp toothed smile, "I am Moon. And I'm not a norman like you probably are thinking..~ So feel lucky I chose to let you live..~"

I froze, there are two types of sea people. Sirens and merpeople... So.... If he isn't a merman... "You mean.... Y-your a siren?-"

He cut me off, grabbing my shoulders and pulling me closer, "Bingo~ Now.... What's your name?~"

I whimpered as he had a tight grip pressing me against him, "M-mmph.. I... I-I'm Sun... P-please don't h-hurt me-"

He kissed my cheek gently, "Don't worry my little sailor boy~ You're going to be fine~ I don't plan on doing anything... Otherwise I would of already~"

I blushed and tried to push on his chest, "I-I- But why?-"

He huffed and pinned me to the wall, "Like I said... I don't plan on anything..~ At least nothing too big~"

I blushed brighter to the point my face was probably pure red. He chuckled at me, "Well sailor boy... How about you take a rest now~ Heaven knows how long you were sailing~"

He started singing to me and the odd feeling from before came back. All I wanted was to do as he wished...

"Go to sleep Sunny~"

"O-ok Moon..~" ,and like that I couldn't even fight it, falling asleep in his arms.

Moon's pov:

Oh how I loved my new sailor boy~ he is so cute when he's scared~ As cute as it was I wished he would hold me without such a struggle... For now I'll let him rest though... I picked him up bridal style and took him to a makeshift bed I had and layed him on it.

Oh how sweet he was~ I put a coat from a past victim's cargo over him and saw him seem to snuggle into it. It was adorable to watch~ However I had work to do... I dove in the water and swam to the surface, scouting for any other trespassers. Nobody was around so I dragged Sun's boat under the water, flipping it so nobody knew he was here.

Now he can't be taken as easily~ After checking again for anyone else in the area I dove back to my cave and dried off. I sighed as I could now return to my sleeping prize, "Mmm..~ So cute as you sleep sailor boy~"

I layed beside him and closed my eyes. I smiled but suddenly woke up before I could fall asleep, looking to where I felt pressure. He looked to be clinging to me in his sleep. God it was so cute to watch him..~ I blushed and put an arm around him before falling asleep as well. Nothing could stop me from keeping my sailor boy now~
