My Wife's Mother

My wife's mother, is better than my wife! Woo-suk married his wife Yoo-na because he loved her, but in the end, they go through a period of ennui and he's not happy with their sex life either. One day his wife goes to work without even making him breakfast and her mother comes home. She's a young-looking woman good enough to be in her 20s with a tiny waist and big breasts.
