Chapter 10.6
"He said that wasn't it, but Woojin was already unbuckling his belt and unzipping his pants. Anxious, he forgot the first rule. Woojin carefully embraced him, covering his back with his chest, and slowly kissed his nape and cheek.
He pulled down Haewon's underwear and kneaded his moderately plump buttocks. Haewon slightly spread his legs and turned his head back towards him. His long eyelashes blinked slowly as he gazed at Woojin.
With a dizzying twist of his upper body, Haewon reached out and grabbed Woojin's nape. Clenching his hand, he pulled Woojin down and deeply kissed him. Their tongues didn't mesh perfectly, the movement of their tongues in each other's mouths was explicitly visible. Their flesh entangled messily, each urgently trying to draw the other in further. Woojin rubbed against his tongue and bit and swallowed his lower lip.
"Ugh...!"
As Woojin sucked hard enough to hurt, Haewon detached his lips and licked his sore lower lip with his tongue. Haewon murmured,
"It's strange."
"What is."
"When we broke up before, actually... back then..."
"Actually what."
"No, it's not that, but there was a time when my lips hurt too much. It hurts just like that time."
"What are you talking about? We were apart, why would your lips hurt? Who did you kiss?"
"...What?"
