Yunho came to Sunmi's house to inform her that he's quitting but she's already waiting for him in sexy lingerie ready for the fucking for one last time
Bora is annoyed that she keeps running into her ex-boyfriend and hates that she still misses him. So, she drags into a motel to fuck all day. Shagging was so good had her forgiving him mid sex. (Post-Breakup sex)
Sunmi guesses exactly the reason for Junho's outings and wants Yunho to rail her right infront of the camera Junho set up to give her son a good fap material.
Bora is extremely bitter and obsessed with the idea of breaking apart Yunho & Yoosun. So, she stalks Yunho throughout the whole summer. One day, the in-laws go on an outing together with Hayul too, she stalks them through the entire day. She feels that she wasted her time doing so as nothing suspicious happened during the whole day, but later at night her fears come true as she clearly sees Yunho and Yoosun fucking passionately. She interrupts them and gives them a good scolding & even threatens to snitch.
After a boring sex session with her husband, Yoosun wants to get a taste of real dick from her husband's brother who was right behind her room's door waiting to fuck her.
