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.
Sang Hee was avoiding Jun-Ho after smelling a different perfume on him, which made her think he was seeing someone else and upset her. Jun-Ho grabbed her, pinning her face-down, and started kissing her. He turned her on by squeezing her nipple and began to undress her. Overwhelmed, she couldn't deny him, and he penetrated her on the sofa. After they had sex and he creampie her, he wanted another round, but she was tired and asked for a break.
He said he wanted to try something new and asked for a tit job, which she had never heard of. He then asked her to lick his tip, and as she tried to lean away, he pushed himself into her mouth and came. He apologized, saying he couldn't hold back. She then asked him to do her. To tease her and make her more turned on, he fingered her anus, which embarrassed her. Both of them came, and he creampie her again. She thought he was going for another round, but he revealed he was just starving.
