Sun/Moondrop x Reader

Territorial

He was pissed. Scratch that, actually- he was beyond pissed. Livid.
"Uh, hey-"
"What are you doing." Moon hissed, dragging me into the daycare before slamming the door shut. He looked me up and down. "What are you wearing." These weren't even questions- they were more like commands.
"You shredded these! You did this!" I lashed back; there was no way in hell I was going to let him blame me for his actions. Why is he acting so weird? He'd normally be drooling over this. Moon hadn't seen Chris, either; he had left before I opened the door.
Unless...
"Are you spying on me!?" I blurted.
His burning gaze diverted to the floor as he snarled defensively. "Not your business." He growled.
I was right, and Moon was jealous.
"You are!" I concluded loudly. Moon crouched down to meet my eyes, baring his teeth.
"Alone with him. Dressed like that." He hissed, prodding me in the chest with a claw.
"He didn't do anything, he just walked me back!"
Moon didn't seem to buy that explanation.
"Adult." He growled lowly.
"Well, yeah? You have to be in order to work here. Hell, I'm an adult!"
"You're an exception." He muttered, but then raised his voice as he pointed out at the door, "HE is NOT."
I nodded bitterly, aware that I wouldn't win this conversation.
"Filthy human hands..." He growled to himself as he looked me up and down again, "He needs to know."
"Needs to know-?" I repeated as Moon leaned forward, placing his mouth on my neck. I could feel my heart race as my face went red; he's giving me a hickey! A growl resonated from within him as he unlatched after a couple of moments, a faint smirk flickering on his face.
"He needs to know who you belong to."
I was at a loss for words as the lights flicked back on. Moon grunted and winced, his body shivering as Sun took over, at which he stood to his full height with a bright smile.
"Oh, Y/N! I've missed y-" he gasped when he saw what I was wearing. "Good heavens! Your outfit!" Sun cried out, focusing on the gashes in the jeans, "Did Moon do this? Where are you hurt!?"
I managed to pull myself out of my shocked state, still taken aback by what Moon had said. "N-No, I'm not hurt, Sunny! Moon was just really excited to...uh..." I trailed off, not sure how to word it.
"He got to explore!?" Sun exclaimed in dismay, putting his hands on his head, "He STOLE my playtime with you!" He groaned with defeat.
"Sun, we can make time later so that-"
"Time?" He interrupted, looking over at the clock, "We've got some time, sunbeam." He grinned mischievously as he wrapped me up in his arms to take up to his room.
"But-"
"No arguing allowed!" He instructed playfully, gently tossing me on the assortment of pillows. I gazed up at Sun, who was whirring up a storm as he made his way on top of me.
Looks like I'm not getting out of this one. I wasn't mad about it, though. He gently turned my head to the side, exposing my neck to him.
"What's this?" He tapped a finger on the hickey Moon had given me.
"Oh, uh, it's a hickey. It's like a kiss that leaves a mark."
"So...Moon marked you?" He tilted his head curiously, "Why?"
"Well, um, he didn't like that I was talking to a coworker...but Chris is a nice-" I cut myself off with a yelp as Sun lunged forward, burying his face into my neck as he created hickey after hickey.
"S-Sun!" I gasped, immediately flustered by his actions; I could feel the ever-so-familiar heat return to my face. He eventually stopped, but kept his face planted in the crook of my neck. A moment of silence passed before he whispered something under his breath.
"What did you say?" I prodded curiously.
"M-Miiine..." Sun mumbled possessively, his hands firmly grasping my sides.
This was new.
"Oh?"
"T-Tell me you're mine, sunbeam..." he pleaded quietly, trailing his fingertips down my back.
The request filled my stomach with butterflies.
"I'm all yours."
