In this world where the number of girls posting erotic videos on SNS is rapidly increasing, I found an account that was broadcasting to the world how she was having fun playing with a masochistic man. After negotiating with her to let me film her, she readily agreed. She sent me a video that was likely taken with her smartphone, and with the cooperation of the masochistic man she often plays with, filming began... The leg torture and forced ejaculation that were filmed just for fun were actually man-playing by an ultra-aggressive, genuine sadist.
