I drove them around while he fucked her [cuckolds perspective]

My wife Sara, and I had been together since Junior year of college. So, she knew, and was also friends with most of my college buddies. One of those friends was a guy named Derrick. He played on the football team and was always looking pretty fit. They got along well and there was always a flirty attraction between them over the years. Our friend group was always pretty fun. So, topless or naked hot tub parties were common. So were body shots or playing truth or dare. What I’m saying is, over the years, Derrick had seen my wife naked and even had her titties in his mouth on numerous occasions. He was also aware that I would let him do anything with her if the opportunity ever came up. I don’t think he actually believed me, but I’d made comments to him enough that he knew there was at least a possibility of it being true. He happened to be in town one weekend and the three of us went to a local dive bar. The two of them were catching up. As they drank more, they got flirtier with each other. And she began to touch him more. At one point I saw her actually rub her hand on his cock over his jeans. I told them if they are going to act like that, maybe we should go somewhere else. When we got to my pickup, she was all over him. They were making out against the truck. Sara knows she has permission to do anything she wants with certain people, and he was one. So, she had no problem kissing him in front of me. I unlocked the truck and got in. She got in the front seat and he got in the back, behind her. As I was driving him back to his hotel, she crawled in the back and straddled him. As she sat on his lap, facing him, they talked and flirted. His hands roamed around her body. I said, “if you’re going to sit on him like that, you should at least show him your tits.” She immediately pulled her top off and he started sucking on her tits while she grinded her pussy against his hard cock in his jeans. I took some backroads and slowed down as things progressed. Somehow they managed to both get naked. Over the course of the next hour, they did everything you could think of. She had his cock in her mouth, sucking him off. He made me pull over at one point, so he could open the door, bend her over and eat her ass and pussy. Eventually I parked the truck. As I sat up front slowly jerking my hard cock, he bent her over and fucked her doggy style until she came on his cock. Soon after, he said he was going to cum and I told him to cum deep in her. He absolutely filled her pussy as he came hard. When they were done she straddled him as his semen leaked out of her used pussy all over his lap. I then drove him to his hotel and dropped him off, before taking her home. When we got to the bedroom, I opened her legs up and fucked her used pussy still full of his cum. It was the best sex I’d ever had.
