Maria had been living with her daughter and her son-in-law together since they married. Maria was bothered by the way her son-in-law kept looking at her chest. She thought it might be just a man's nature and it couldn't be helped, but Maria herself began to feel strange. One day, when she went to the couple's room to clean, she found the son-in-law looking at an adult magazine and masturbating. Seeing that aroused Maria; unable to control herself, she went back to the living room, masturbated, and then fell asleep. The son-in-law then came in.
