That's how I convinced her to give me several blowjobs in my car. Normally she was afraid to be seen doing it, but all I had to do was ask her to do a twosome or a gangbang first, and she usually went along with it. A couple times pedestrians walked by or people in other cars saw some of it. One warm evening, she blew me in my car with the convertible top down. That was cool. But I wish more people had walked by. I'm sure the only thing they saw was her head bobbing up and down in my lap. Or, there was the time I screwed her on a park bench on the bike trail by the river, I am sure all anyone saw was my bare ass bouncing up and down between her legs. And one night she let me fuck her on a chaise lounge on the patio next to her apartment complex's swimming pool. It was dark so I doubt anyone saw us, but it was still more fun than doing it in her bed.
One of the only times anyone saw us having public sex was another weekend when we went back up to that same picnic spot in the mountains, except that time we went up there for overnight camping. We pitched our tent in a clearing near the rocks about 100' off the trail. There were lots of trees and a few bushes, and we didn't see anyone else on the trail, so Laura was comfortable we had privacy. Unfortunately, being alone meant I had to pretend to listen to her as she gabbed on and on. I was hoping the sex would be worth putting up with it.
The first night, we only screwed in the tent in the sleeping bag because it got cold. The next day though it was sunny and warm, and we had sex outside a few times, camera rolling. We also skinny-dipped where the stream feeds into a secluded cove about a half mile away, but no one was around, so it didn't really count as public sex. But even though she hadn't seen them, I had seen noticed some hikers walk by on the trail a few times. It took me awhile to convince her, but she let me strip her naked and tie her blindfolded to a tree after I promised to lick her to the best orgasm she ever had. She never got the orgasm I promised, but a couple of hikers got a good show of her nakedness and of me getting a blowjob from her while she was tied up. I saw a hiker looking in our direction and then hand his binoculars to another guy. Too bad they didn't come closer. I would have let them have a much better look. Maybe even fuck her. Oh well.
Another time I made a video of her sitting nude in a lawn chair and masturbating on her balcony. She was facing indoors so I don't think any of her neighbors saw anything, but my buddies saw it all when I shared the videos with them. Sex in public places was fun, but even that got boring after awhile.
Over the next few weeks, I made several more porn videos. I filmed her sucking on a dildo and wearing a schoolgirl outfit and pigtails. But I was running out of kinky things she'd agree to do. So that's when I started a full court press to get her to do a three-way or a gangbang with my friends from work.
