marked up

"joonie...joon, honey what's up, what's w-with...ah...all the marks? fuck..."

namjoon paused for a second to mumble "nothin'...just like marking you up..." he continued to kiss seokjin's skin.

seokjin raised an eyebrow at this. "why? you only mark me when i go out...are you jealous or something?" when he felt namjoon tense slightly, he knew he had gotten his answer. "fuck babe, you're jealous aren't you?" namjoon stopped and sat up, eyes wide.

(aka namjoon is sensitive and wants to make sure everyone, especially seokjin's friends, know's what belongs to him)
