Scene 1. Myeong-hoon usually admires his sister-in-law, Lee-seo, and has always been looking for an opportunity to have sex with her. One day, while her husband is on a business trip and she is left home alone, Myeong-hoon disguises himself as a pervert, scares his sister-in-law, and steals her underwear. Due to the incident, the terrified Lee-seo asks her brother-in-law to accompany her that night, and Myeong-hoon takes the opportunity and has sex with his sister-in-law.
Scene 2. Unlike her husband, Do-hee admires more her brother-in-law, Ji-seong. One day, when he comes to their house, Do-hee accidentally sees his brother-in-law’s naked body and becomes excited. Ji-seong noticed it, so while his brother was not looking, he forcibly caressed his sister-in-law. Do-hee, who doesn’t hate it, breaks down for the first time in a long time.
