This is a great story. The son told us that his father (65 yo) is married with his step-mother (47 yo) who raised him since he was 10. Two years ago his father was hospitalized in a private clinic and he told his son and his wife that he knew they where having sex for awhile and he didn't mind. He asked them if he could watch them over the net. He says they do it from home and his father watches them from his private room at the clinic.
