I picked up a pair of girls and got them to join me in watching masturbation, but one of them seemed a little strange. When the male actor appeared, she seemed to glare at him, or even look depressed, rather than feeling embarrassed. However, she was doing naughty things because she couldn't get any pocket money unless she worked together with her friends to watch the masturbation, but it turned out that the male actor was actually her younger brother!
