Then they go to Motel to continue their "Sexual Job"! Sang Hee Cha began acting proactively and suggested to give a boobjob to Ho-kim after he just finished to creampie her, he finally gets a boobjob which he finds it very hot. They then continue to have sex again.
Sang Hee was absent-minded while Jun-Ho called her a few times. He said he finished cleaning the locker area and asked if she needed help elsewhere. She said she could use the help since she hadn't gotten much done. Jun-Ho noticed her distraction and went to lock the door. When she asked why he was closing it, he came over and grabbed her boobs, saying, "So I can do this." She thought he was acting strangely all day. Internally, she wrestled with her feelings, thinking that if she truly cared about Soo-Ah, she would stop him right there, but she also felt she couldn't live without Jun-Ho anymore.
Jun-Ho remembered a new technique he had learned from Mi-seong and wanted to try it on her to see her reaction. He started performing cunnilingus on her until she orgasmed. He then immediately began to finger her again. She told him to wait, as she had just come and needed time to build up to another orgasm. He started kissing her, and she told him to stop teasing her, saying she needed him inside her. He found this adorable, lifted her leg, and penetrated her in the missionary position before switching to doggy style and creampie her. Throughout the act, she thought they should not be doing this if she cared for Soo-Ah, and that she was such a terrible mother.
After having sex with Jun-ho in the car, she worried that going back would look suspicious because of the smell and asked if there was somewhere they could wash up quickly. He then drove them to a motel.
He booked a room, and the receptionist asked if it was for a short stay. Sang Hee, so embarrassed, said they were just there to wash up. After entering the room, he started to kiss her, but she reminded him they were there to clean up. He suggested they could do it while in the shower, and she agreed.
One more time, he started to undress her. He saw she was already wet and told her to stop teasing him, then said she was so cute. They went to the shower and had sex in there. After coming to the bedroom, they had sex in the cowgirl position, and he creampie her. Both then went to bed, worn out from the sex.
Jun-ho woke up, saw it wasn't that late, and started fingering her, trying not to wake her. She orgasmed so hard that she peed in the bed. He then knelt to do her doggy style again. She said it was embarrassing that he saw her like that, but he reassured her, saying it was okay and reminding her of a time when she had comforted him as a child, telling him it was okay.
He then said they should finish because Soo-ah would get worried if she was running late. She texted Soo-ah that she would be much later than usual, too embarrassed to say anything more. He got rock hard after hearing this, started having sex with her, and after trying different sex positions, creampie her again. Then they went to clean up in the shower again. He said, "Just one last time," and they continued to have more sex in the bathtub.
Jun-Ho Kim and Sang Hee Cha found it difficult to talk freely after having sex. While they were cleaning a building, Jun-Ho couldn't stop staring at Sang Hee's body. She noticed, which made her uncomfortable but also aroused. Unable to take it anymore, she confronted him. He asked if she remembered what happened between them and then kissed her. She didn't push him away because she liked it, though she warned that someone could walk in. He was desperate for her, fingered her to orgasm, and then pulled down her pants and penetrated her. Despite thinking she should say no, her body gave in, and she was overwhelmed by pleasure she had never felt before, realizing there was no going back. After he creampie her, they cleaned in silence.
Now, Jun-Ho knew she wouldn't avoid him anymore. Whenever they were alone, he would have sex with her in various places like the cleaning company's meeting room or an empty studio apartment, usually when their colleague Soo-Ah had gone home. Sang Hee would always start by saying no, but he would always convince her to continue. Jun-Ho was happy to finally have a chance with the woman he admired.
