It had been about six weeks since I had seen my girlfriend, Lori, and I was so incredibly horny. She met me at the airport wearing a black dress with a mostly open back and a full skirt. She was waiting right by the gate when I got off the plane, and I lifted her up high in the air and hugged her. We collected my luggage, put it in her car and set off for home with me driving. Shortly afterward, we were on a four-lane road that heads south through rolling countryside.

Lori kissed me repeatedly, and I put my arm around her shoulders. She then put her head in my lap, snuggling up to me. My cock was hard, and it pressed up against her cheek through the fabric of my trousers. With my free hand, I lifted the hem of her skirt to discover, to my great delight, that she wasn’t wearing panties!

I began to caress the cheeks of my girl’s beautiful ass and the lips of her wet cunt, eliciting an occasional moan from her. I then used her wetness to insinuate a finger into her tight, hot asshole, sliding it all the way in to the knuckle. Lori nestled closer to me and used her free hand to unzip my trousers and free my cock. She took it in her mouth with a soft moan of desire.

All this, of course, was making driving difficult. Fortunately, traffic was relatively light. We approached an eighteen-wheeler, and I moved into the left lane to pass him just as we crested a small hill. I drove by him and continued on, planning to move back over into the right lane. However, as I looked in the mirror before changing lanes, I noticed that the truck had gained speed coming down the hill and was now too close for me to pull in front of him.

The driver pulled up alongside us, on our right, then matched his speed to mine. I realized that he was looking right through the window into our car and that he could see Lori’s bare ass, with my finger inserted deep in it! I found that extremely exciting and made no effort to either pull away or cover her up. I think Lori realized that something was going on, but she continued sucking my cock hungrily while caressing my balls.

The truck driver and I played tag for quite a while, him falling behind going up hills, me slowing down in order for him to catch up going down hills. From time to time, I would have to pull over in front of him, and then he would flash his lights as a signal for me to move back over into the left lane. If I had fallen in behind him, he would slow down, stick his arm out the window and wave me up along-side the cab of his truck.

All the while, Lori was giving me unbelievable head, and my cock was bursting at the seams. How I kept from coming, I’ll never know. My right hand was busy with her cunt and her ass as her hips moved back and forth, encouraging me to reach further into her. When she was sufficiently lubricated, I worked a second finger into her asshole, which caused her to redouble her efforts on my throbbing cock.

When the truck driver was right alongside us, I would spread the cheeks of Lori’s ass to allow him a better view. But then I had to fall behind him into the right lane because of the traffic. Lori wanted to turn over onto her back, which she did, and I raised the hem of her skirt to her waist. She now lay with the lower half of her body completely exposed, her right leg draped over the back of the seat and her left leg pressed hard against the door.

The late-afternoon sun streamed in the window, completely illuminating her smooth belly and thighs. I spread the swollen, engorged lips of her cunt, reveling in the wetness I found there, and busied myself with her clitoris. Her hips were moving back and forth, and her eyes were closed.

I got back into the left lane and moved alongside our trucker, giving him a fabulous view of my sexy girlfriend. I had Lori hold her cunt wide open while I caressed her clitoris and her stretched asshole. I moved two fingers in and out of her cunt, again and again and again. The trucker went nuts!

After about ten miles of this, during which Lori must have had half a dozen orgasms, we approached a red light, which forced us to stop. The trucker pulled up right beside us and began imploring me to pull off at the next rest stop. The thought of a threesome in the back of his cab did have some appeal, but the thought of hopping into bed with Lori for a prolonged afternoon and evening of fucking had more. So when the light changed, we sped away like drag racers.
