The brothers-in-law in the movie are lucky to have sisters-in-law who are both beautiful and lewd. Dinner with family is also the time when clumsy stories start to happen. The sister-in-law, dressed provocatively and seductively, was the cause of his brother's lusts, and he had drunken yeast in him, so he couldn't control himself and many bad things happened. Perhaps her sister also had feelings for her brother-in-law for a long time, so when the brother committed rape, she did not resist at all, but just lay still and indulged as he wished. It is true that the sisters-in-law are lewd.
