I love my wife very much. I would do anything for her (short of permanently hurting or killing someone but everything else is fair game). My wife loves to make me do things that put me outside of my comfort zone, especially when it comes to sex and sexually provocative situations.
One day we were driving north on I75 through central KY on our way home from visiting some family. It was a very nice day in early summer and my wife had me drive nude as she loves to do as often as she can. She loves seeing me try to hide myself when we go past vehicles that sit higher than ours and the other drivers can see me naked. This was back when we had an F150 so it was usually the big trucks that I was worried about (now we have a crossover that sits lower so it's even more embarrassing). She would always tell me to slow down, or speed up, so the big rig would be along side of us for a while in the hope that the driver would look over. When they did she would make sure to point to me and let them know I am naked. It's certainly a bit exciting but very humiliating when they see me. But I love my wife.
As we were driving just north of Lexington my wife spotted a couple of bikers on the side of the road on the south-bound side. They were pretty good-sized black guys and were riding nice highway cruiser-type bikes. My wife said "they might need help. Turn around and let's go see if they need anything." Being the good samaritan that I am (and because my wife told me to), I said, "ok, I'll turn around at the next interchange", which was about a mile up the road.
As we pulled off and turned left to go get on the south-bound side I told my wife I was going to pull over and put some clothes on. She said, "no, I want you to stay naked and see what the bikers have to say about a old naked white guy driving down the freeway." My wife loves to put me in compromising situations, especially out in public, so I knew I was not going to be able to talk her out of it.
So we headed southbound and about a mile and a half later came to where the bikers where parked on the shoulder of the freeway. I pulled up about 50 feet or so behind them and put the truck in park. My wife opened the passenger door and stood just outside of the truck and yelled up, "do you guys need any help?" They both walked up to the truck on the passenger side to talk with us. My level of humiliation skyrocketed as they got closer.
They started talking with my wife as they got closer and told her they had just called a friend to come with a trailer to pick them up. When they got to the passenger door they both looked in and saw that I was sitting there, naked as a jaybird and did a double-take. The bigger of the two said, "are you two having fun driving down the freeway with your man naked?" My wife said, "yes, we are. He's my husband and does what I tell him. Unfortunately for him I like to embarrass and humiliate him."
The bigger of the two said to my wife, "well, our friend is about 30 minutes away. How about you have your man suck our cocks while we're waiting?" I looked at my wife and saw that shit-eating grin she gets when I'm going to be on the receiving end of some kind of sex so I knew I wasn't going to get out this. She said, "sure, he'd love to, wouldn't you honey?" I just looked at her, then the two bikers, then back to her and nodded sheepishly.
The F150 was a Super Cab and has these back doors that open like the old suicide doors so my wife told me to crawl out the passenger side of the truck. Then she opened the back passenger door which then blocked the view at the passenger seat from the vehicles coming down the freeway. The bigger guy sat in the passenger seat and pulled his cock out for me to suck. It was freakin' huge! It was at least 8 inches long and 6 inches around and it was soft! He reached up and grabbed my head and pulled me down to his lap and told me to suck him nice and hard.
