AUTO SWAPPING Last summer my wife and I, on the way back to our home in the Southwest from a vacation on the East Coast, had an experience that I would like to share. I am 36 years old and stand six feet two inches tall. I have sandy hair with some gray in it, blue eyes, and a good build, but I'm not exaggeratedly muscular. I am a habitual flirt, a habit that I acquired through a combination of my wild life in the service and my sales career. My wife is 37. She's five foot six, has brown hair, beautiful bluegreen eyes, and she's a knockout. She is always catching men's eyes with her fantastic body, but she doesn't ever seem to notice. We have been married 12 happy and sexually active years. We have, like most modern couples, considered swinging, but in the few situations where we had an opportunity to do it, we found that it was the fantasy and not the act that appealed to us. Besides, my wife's teaching career could be jeopardized if we were discovered to be swingers. One very pretty afternoon we had been Driving on I-24 from Chattanooga to Nashville, which is a beautiful drive. We were in our custom van, and my wife was watching the river that runs alongside the interstate. As I passed by a Toronado, I heard her gasp! When I asked her what was wrong, she said that the girl in the car was giving the guy a blowjob. As we talked about it and she told me how attractive they were, I decided to look for myself. She told me not to embarrass them - if it were us, we wouldn't appreciate it. But being a true voyeur, I ignored her objection and got into the right lane and slowed down slightly, causing the Toronado to change lanes to pass. As it pulled up beside us, I matched their speed, and looking down into the car saw a beautiful pair of legs in the passenger seat. The woman had on a skirt and the position she was in allowed me to see all of her legs and just a trace of her lacy white panties. She was leaning over the driver's lap, doing an excellent job on his dick. He had his pants down around his knees and was oblivious to anything but driving and sex. After a few seconds my wife's curiosity took control, and she got between our captain seats to look out my window too. She remarked on what a nice dick he had and how sexy his legs were. We were entranced with what we were watching, and she instinctively rubbed my now-hardening dick through my jogging pants. We must have been blocking traffic because our trance was broken by a horn from a truck behind us. The other couple immediately looked around and caught us staring. An embarrassing situation was relaxed when they both smiled at us, straightened their clothes, and drove on. We laughed and talked about how attractive they were and how sexy it had been. My wife, still beside my seat, took my dick out and gave me a 20-mile blowjob while I reached down inside her pants and felt her hot cunt juice flow over my hand. Just south of Nashville we pulled into a rest area so she could clean up, and there was the white Toronado. I parked a ways off and opened a beer while my wife went to the ladies' room. She was in there a long time, and when she came out she was laughing and talking to a beautiful girl in her mid-twenties. about five foot two, slim, but with a nice round ass. Then I noticed the skirt and realized it was the girl in the Toronado. The girl went to her car, and my wife came back to the van. When she got in she said they were laughing because they were there for the same reason. She discovered the girl was from Colorado and was also a teacher. She asked if I would mind if she asked the couple to share a joint with us. I certainly didn't and pulled the van over by their car. When they climbed in, I was speechless at how cute this girl was. We exchanged first names and my wife rolled a joint. As we smoked and chatted, I noticed my wife paying an unusual amount of attention to the guy - a 26 year old law student who could be Burt Reynolds's kid brother in looks and personality. I couldn't be too critical, though, because I couldn't take my eyes off the little doll sitting across from me with her legs propped under her on the seat - exposing again those lacy white panties. We must have spent two hours at that rest area smoking, drinking, and flirting. The conversation centered on sex, after talking about how sexy it had been watching them before and what it had led us to do. They had the same negative feelings that we had about swap clubs and swinging with acquaintances; but it seemed we all enjoyed this totally unplanned encounter. Knowing it would be unlikely that we would meet again, and with the pot having loosened us up a bit, we were thoroughly enjoying the moment. I noticed it was getting dark and we all needed to get back on the road. I leaned over to kiss the little sweetheart good-bye. When our lips met, she put her arms around my neck and her tongue in my mouth. With this I lost my senses and kissed her far longer than I knew I should have. Afterward I looked to my wife, expecting a reprimanding look, only to see her kissing the young man. I looked back at his wife, who had the same thoughts about him, and we laughed with relief. Our spouses regained their composure and laughed with us, all understanding everybody else's feelings. Then the husband asked which way we were headed. I said that in Nashville we were going west on I-40. He said that they, too, were going west to Memphis. Then he suggested that maybe if every one agreed, we could switch passengers for a ways and continue this a little further. We all immediately agreed and together made some rules. What we all agreed to was that he and my wife would take a ten minute start and we would both set our cruise controls on 55, so there would be no way to see what the other couple was doing. We agreed not to stop but to set our odometers for 100 miles and pull over and change our wives back. We could do whatever we wanted while driving and afterward would not ask questions. We gave only first names and afterward would only have memories. As the Toronado pulled away, the girl and I talked for the ten minutes and she confided in me that she had hoped something like this would happen. She said that she loves adventure and that this was the most interesting situation that she had ever experienced. I kissed her and held her close, once more enjoying her firm body next to mine. I reached around to feel her ass under her skirt, but she stopped me, reminding me of the rules. By now the ten minutes were almost up, and she asked if I would mind stripping before we started. I took my clothes off and got behind the wheel and in no time was on the interstate with the cruise control set. She put a nice tape in the cassette player and moved to the back of the van and, as I watched in the mirror, began to undress. She first took off her skirt, finally revealing completely her beautiful ass in those panties. She then took off her shirt. To my delight, her tits, which I knew were not large, were as perfectly full and rounded as her ass. As I watched, she took her nipples between her fingers and worked them to full erection. They were about a half-inch in diameter and honestly a full inch long. Seeing my reaction, she came forward and knelt beside my chair and, with her tongue touching my ear, asked if I would like to suck them as much as she wanted them sucked. I simply nodded yes, and she said that she would steer the van and for me to lay back and enjoy myself. She leaned across and took the steering wheel, which placed her tits in my face. The nipples were very hard and tasted absolutely great. As I took one entire breast into my mouth, I could feel that nipple on the back of my throat. I instinctively swallowed and felt my throat take hold of it and release. It was an accidental discovery, but when she went wild, I continued as though I had intended it. I moved from one to the other, sucking, swallowing, and fondling those wonderful tits for quite some time. I then reached down behind her and felt that full, firm ass. As I rubbed her ass, she arched it upward, allowing my fingers to move to her cunt, which to my delight had already soaked her panties. With her still steering the van, I slipped out of the chair, and she got in the chair on her knees and leaned against the steering wheel. I realized that this was not the safest maneuver, but at the moment it didn't matter. I slipped her panties down her legs and off. Now we were both completely naked, and I took a long time feeling and admiring her beautiful body. While pinching her fantastic nipples, I ran my tongue down the small of her back and licked her. Her skin was so soft and sweet. I took one hand off her nipple and reached between her legs and felt her swelling clitoris. She responded by rubbing her cunt against my fingers. I ran my tongue down to her waiting vagina. As I slipped my tongue into her, l felt her convulse slightly. I asked if she was able to continue driving, and she assured me there was not much traffic and she could handle it. I once again began to tongue-fuck her while holding her nipple and clitoris. I continued this for several minutes until she said she was losing control and traffic was picking up. I stopped, and we switched back to me driving. We were entering Nashville, and for the 15 to 20 minutes it took to get back out on I-40 West, she worked on my nipples with her teeth while rubbing my balls and jacking off my dick. It seemed an eternity until we were once more on the dark highway. As soon as we were, she got up, and with my chair swiveled where I could see to the left and steer, she climbed up and straddled the chair. She put her tongue in my right ear and whispered that she needed to come. At that she lowered herself onto my hard dick. She was wet and slid easily down the length of me until I was buried inside her. She felt magnificent, but I knew I must not lose control. As she fucked me I felt her tight cunt grip me. It didn't take very long for her to reach her orgasm. When she was completely through, we switched positions and she sat on the edge of the chair and drove while I took my time fucking this gorgeous young lady. When I finally unloaded in her, we fondled each other a while and noticed the odometer was at 92. We dressed, kissed, then saw the white Toronado ahead on the shoulder and pulled up behind it. She winked and smiled, then went to her car. When my wife climbed into the van, we had a moment of awkward silence. But when I asked if she had enjoyed herself, and smiled and said that I had very much, she smiled and said she had, too. We laughed, and she said jokingly that all they did was talk. I winked and agreed that they had been great conversationalists. She rolled another joint, and we continued our trip. We made several stops that night and tested the van springs each time.
