Me and the wife were headed up to Vt on a foliage run and we were getting frisky. I was getting a hand job as was she lol. So we wound up pulling in to a rest area its was mid afternoon. There was no one around and we started going at it inside the suv and it was getting heated. We wound up spilling out next to the truck and was going at it with the highway cars going by and some honking. We were at the end of the lot so they couldnt stop or see til the were past the point of getting on. She was getting concerned so we went in the woods a little and kept going at it at a slower pace. After a few minutes I heard a car pull in but didnt get concerned. 5 min later I see someone coming down the path and the wife had her head down so she wasnt looking. It was a guy and he must have been looking to relive himself and when he saw us I looked him right in the eye and gave him a slight wink. So he was taking a leak and went to jerking off as soon as he was sure it was ok to watch. I didnt say a word to the wife as I knew it would shut her down. So I started to get verbal, like "your such a dirty girl, you were begging for me to pull over and stick it deep in you, weren't you?? And she was just moaning and said yes I really needed this. So I smacked her on the ass and started to really pump her deep so she would grunt and moan even more. I was having a hard time not shooting in her. So when it sounded like she was ready to cum I pulled her back up from the doggy style against the tree and turned her slightly so he could see her face and tits as I came inside her as she came and our friend shot a load that was impressive. And I dont know how she didnt see him, maybe she was just in a daze. So we straightened up and walked out the trail and as we passed the spot where our friend was i saw his load across some leaves and chuckled to myself. We came out of the woods and he was pulling out of the lot and just smiled. She never knew anything about it. AH memories,
