they're brave if they did this on their own. My wife and I tried dogging in a carpark off the M25 a few years ago. It was ok at the start with just a couple of men there. But a few more turned up and they were rough. with just the two of us it started to get out of hand. we think a couple of them phoned their mates to tell them what was happening because more turned up and they all knew each other. fortunately my wife is submissive or it could have turned really nasty. even so they really took advantage of her. i felt terrible having to watch her taking it. eventually we managed to get away after about 3 hours. never again
