Sun-Young asks her superior Ho-Jun to train her in a Master-Slave BDSM dynamic. His first command is for her to wear a vibrator while walking around. 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.
Bora is annoyed that she keeps running into her ex-boyfriend and hates that she still misses him. So, she drags into a motel to fuck all day. Shagging was so good had her forgiving him mid sex. (Post-Breakup sex)
