Or the time Yoonjae and Haneul found their parents wrestling as told by Haneul to his imos in Impish Imo

Naeun stifled a moan as Taemin bent down to kiss her neck, on the spot that always managed to make her crazy. As he continued to plant nips and kisses all over her body, she locked her legs around his waist, begging him to hurry.

Chuckling against her bare chest, he brought his hand to cup her bottom, pulling her against him so she could feel how much he wanted her, too.

“Please,” she cried as she placed her arm between them to palm him through his boxers, trying to speed up what he was doing. “Oppa.”
