Marx Soul x F!Reader ~ She's Mine

(Y/N) POV

I sat over Planet Popstar, watching the cute pink creature bounce and eat as he made his journey across the planet. I giggled while he tumbled down a hill, smiling the entire time. His adorable demeanour brought a smile to my face; slim arms wrapped themselves around my shoulders as light purple hair rested on my neck.

"Hello Marx," I hummed, kissing his temple.

"Why were you laughing?" he asked, his voice muffled against my skin. I pointed to Kirby who was still running along the dirt road; Marx Soul squeezed harder, watching the little guy run about with his lavender-coloured eyes. "Stupid Kirby," he mumbled.

"Are you jealous?" I asked quietly, leaning back into his chest carefully.

"You. Are. MINE!" he growled, hugging me as tight as possible.
