OMG all my dreams have come true at once. I walked into a new gym to see just one girl in there. He had long brown hair and really big boobs and a sexy two piece gym kit. I took my chance and told her that I was a gym instructor. I told her that I would give her one free lesson and I would record it on camera so we could then analyse her workout afterwards. I loved watching her squat and bend. She had a great body. But suddenly the lights all went out in a power failure. While we were waiting for the lights to come back on I told her I would give her 6 months of free lessons if she would let me fuck her. I was lucky I had my infrared camera. I was able to record us having sex together in the gym.
