Sex in public gets caught by a voyeur at night

Voyeur knows the places where horny couples come for some private time, in public but hidden from a public eye. He caught two horny lovebirds preparing to have sex. He uses night vision mode of the camera so they can't notice anything out of the ordinary. That hot girl puts a condom on her boyfriend's hard dick and she gives him a ride. He even fucks her from behind for a while but she stops that because she notices there are some people approaching them.
