His second command is for her to perform oral sex on him under a table. She keeps his ejaculate in her mouth for the remainder of the workday, which immensely satisfies him. He then rushes her home for an intense sexual encounter.
Seung-Jo Cha tried to assault her first but So-Hee herself allows him to fuck her.
After coming to his lodging he fucks Yeong-Suk to gain back his, confidence!
