Naeun becomes Siwoo's little bitch. Her master orders her around anywhere, anytime whether it be the in the classroom, in the streets, in the restroom. He explores his slave's exhibitionist kinks and fucks in the restroom at Christmas eve.
Jack went to take a shower, and Ember had a crazy idea again. She went to give a towel to Jack while he was naked, wanting to sneak a peek at his body before he suspected anything. Jack thought Sarah was the one giving him the towel because shampoo foam covered his eyes. Ember saw Jack's erect cock and became soaking wet from the sight, wanting to be fucked by him. She knew he would notice if she spoke, so she went without saying anything and grabbed his cock to give him a titjob. After that, Jack grabbed her and started raw dogging her, then cunnilingus, followed by missionary. He said he wanted to see her face before he came, and then he went to wash the shampoo out. She saw this as an opportunity to leave from there without anyone noticing.
