What's the point of this?! They secretly filmed the user during the shoot!

I arranged to meet up again for a hot user-generated video shoot. What I didn't realize, though, was that there was a pervert on the terrace secretly filming us! He filmed the whole thing – fucking, licking, sucking, etc. – without even realizing it. He probably even jerked off while he was doing it! Would you secretly film me like that and jerk off while you did it?
