All of them got a vacation after Si-Yun scored great on Mock Exams! Its a Villa with a Swimming Pool. Ji-Hyeon is the 1st to strike Si-Yun & they have sex while, Su-Min is listening them having sex, standing outside the room. She is also getting turned on & starts fingering her pussy!
The Madam takes Dol-Soe to the Pavilion and wears an extremely revealing dress and asks Dol-Soe whether the elder would like it. Dol-Soe gets a boner looking at her and she pulls down his pants after which he proceeds to penetrate her.
