When Yuri's husband was hospitalized and she was left alone, her daughter and son-in-law came to live with her out of concern. Yuri was grateful to them, but at the same time, she felt an urge well up from deep inside her body. She couldn't help but stare at her son-in-law's strong body, knowing it was wrong. With her husband away, her carnal desires had nowhere to go and swelled to the point of being uncontrollable. One day, Yuri massaged her son-in-law. She stimulated him with her seductive fingers, casually pressing her body against him, whispering in his ear with a sigh... Yuri was trying to get him to attack her.
