"Hyung."
"Mmhm," Jooheon replied lazily, the vibration of his voice against Changkyun's neck making him squirm.
"Hyung," he tried a second time, fighting to contain a whimper as Jooheon nipped at the sensitive skin just behind his ear. "you-you're gonna leave marks."
"What if I want to leave marks?" Jooheon murmured and Changkyun swore he could feel Jooheon grin, sucking harder to purposefully tease. He groaned, helplessly melting into Jooheon's touch.
"Because they'll see and I'll get into huge trouble. My parents, they'll-they'll--ah Jooheon!"
Jooheon had journeyed his way with tongue and teeth and lips to the underside of Changkyun's jaw, breath hot against his skin and pressing lingering kisses there because he knew it drove Changkyun crazy. He huffed out a laugh at Changkyun's high keening and shaky sighs and in that moment Changkyun kinda really wanted to punch his best friend in the face because excuse you. He pushed Jooheon down onto the bed, straddling his thighs and staring down at Jooheon's stupid smug face with narrowed eyes.
"You're cute," was all Jooheon had to say for himself, a silly lopsided smile plastered on his kiss-swollen lips.
