A son-in-law working at his wife's family company. His mother-in-law is in charge of accounting. He had always thought that she was honest and serious at home, but when she said something like 'Are you interested in my breasts?' he couldn't hold back anymore!! He fucked her during work hours in the office when they were alone!! Not satisfied with just the office affair, he went home and did it again in the bedroom, cumming inside his mother-in-law!!
