Si-Yun is desperate to get out & meet up with Ji-Hyeon, but Song Yeonsun stands in his way & won't ever let him go past her. He begs her but she's not impressed so his only other option is to use violence, little did he know that Yeonsun is a retired martial arts promising talent. He gets put to the ground quite easily. In order to free himself from her grip, he resorts to touching her in her most private parts & he succeeds in doing so he threatens to pounce on her, the only problem is that he made things worse by awakening something in her that is way harder to get from. She takes up his words against him and pounces on him saying: "Don't worry young master, I'll make you feel good".
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.
Do-Hoon sets his eyes on his target; it's Mrs. Lee So-hee's youngest daughter Han Ah-young. He invites her to talk over dinner. Before time got late, he sends her home earlier than expected & planned to meet next weekend. When the time came, they went on a date together, and at the end of the day, they go to a motel together, and they get straight to having sex where Do-hoon takes Ah-young's virginity. He starts fucking her gently and very considerately, but she wants to fuck her the way he likes (roughly) to get him to like her.
Yejin is fed up with Yubin coming over to get fucked by Jinhoo and her "innocent and refined act" in the midst of all that as she feels that her "personal cock" is being stolen. One day, she ordered a suspicious pack (it's full of sex toys) and stated that she'll "Bring out the fake bitch's true colors". When Yubin arrived at their place, Yejin welcomed her and gave her a cold drink (it's spiked). After drinking the drink, Yubin fainted and then woke up to find herself tied up to the bed, she asked 'what's going on?' Yejin shamelessly lied to her and told her that Jinhoo is too worn out from fucking the both of them and that they have to give him a little LESBIAN show to get him turned on. Yubin didn't mind if it's for the sake of Jinhoo and then she asked about what she's supposed to do, Yejin told her to just lay back and enjoy getting played with her body. Yejin started her show by shoving a vibrator in her victim's pussy, then she proceeded to bring out her Custom-made Strap-on that is the exact same size as Jinhoo's cock. Before fucking her, she wanted to humiliate her and make her beg for it, so she told her to say: 'Please put that cock in my slutty pussy', as soon as Yubin uttered those words, Yejin started fucking her with the strap-on with Jinwoo watching through the whole show. When Yejin noticed that he's turned on, she invited him to join them, Jinwoo hesitated at first as Yubin's pussy is already preoccupied with the strap-on. Yejin told him to stick in her BUTTHOLE as it' the only free hole, he still hesitated because Yubin never tried anal sex before, the two girls managed to convince him, and then he proceeded to thrust his dick in her asshole. Yubin felt a pleasure like never before as she got fucked in her pussy and had her anal virginity taken simultaneously to make for a mind-blowing double penetration experience, she never had before.
