We were riding down the interstate, my girlfriend Anna and I. It was July, sunny and very hot, and we were on our way to Arizona to visit her parents. She was out of school for the summer and I had taken a few days off work to drive out to the ranch. It was sure to be a relaxing time, since things moved slower there and there was not much to do besides play with the various animals.
We drove in my Jeep Wrangler, the top pulled down to let in the sun. My girlfriend lounged next to me, her seat tilted back and her shirt off, with only a bathing suit top and short soft cotton shorts on. She had rubbed on some sort of sun tanning oil, and her olive skin had a pearlescent quality as the sun shone on it. Anna is half Spanish, so she has a Mediterranean look about her, dark hair and eyes. She is tiny, only 5’-3”, with a small waist but beautiful curvy hips and a typically Hispanic ass that attracts lots of male attention. Her breasts are not large, but they suit her body and are more than a handful. She was currently filling out the miniscule bikini top very well.
Before long, as always happens on any freeway drive, we got caught in construction traffic. It began to look like we were not going to be going anywhere fast, so I began to look around at the other cars. Beside us was a black-cabbed semi truck, and I noticed the driver was looking down at my almost-naked Anna. He was not a bad looking guy, maybe mid-30s, with long hair and a goatee. He was grinning down at my little girlfriend, no doubt thinking lonely trucker thoughts.
“Don’t look, but the trucker next to us is checking you out,” I said.
“Really?” Anna asked, smiling. She always got a kick out of guys wanting her, although to my knowledge had never cheated on me or even shown more than her pretty smile to one. She put on her sunglasses and tilted her face a little to the right to see him.
“Wow, he really is checking me out,” she said, still smiling. “Creepy.” From her tone of voice, I could tell she was not that creeped out by this.
“Why don’t you give him a thrill?” I asked.
“Like what?” she shot back, her tone a little shocked.
“Show him your tits,” I said, and gave her a devilish grin. “He probably hasn’t seen a pair in a long time, not as nice as yours anyway.” This got her grinning wider, and after another second of hesitancy to preserve her honor she agreed. She began rubbing more oil on her stomach, then lifted the cups of her bikini top over her small firm breasts for a few seconds, exposing her dark brown nipples that were as hard as I’d ever seen them. Then she pulled the cups down again. She turned to me and grinned triumphantly.
“That’s it?” I asked. “That was barely anything. Give him a real show.”
She was hemming and hawing so I looked over at him. He was staring even more intently at her, and I could tell he wanted more. “C’mon, Anna, this guy seems alright. Give him a real show, something he can jerk off to at the truck stop!” A wide grin broke on her pretty face again, and she pulled the tanning oil back out. I thought she would lift the top again, but instead she untied it from around her neck and back and removed it entirely. Her perfect 19 year old tits were in plain view. She poured oil all over them and began massaging it in, never covering more than one at a time. She rubbed the oil all over her tummy, getting lower and lower. I could tell from the look on her face she was getting excited. After 10 minutes of this tease show she surprised me.
She hooked her thumb in the waist band of her short shorts and pulled the front down. She wiggled her ass in the seat until her shaved pussy was totally exposed. She then poured oil on it and began to rub and finger herself for our trucker friend. Her body was gleaming from the oil, and she arched her back and thrust her tits to the sky as she worked herself towards orgasm. She came soon, loudly. She kept her thumb hooked so as to show her shaved mons, and brought her soaked finger to her mouth and began to lick the juices off it. This was new since she had never been interested in her own taste before.
I was thrilled at her display, since I had dreamed of watching her show off for a long time. I was glad it got her so turned on.
Traffic began to move then, and we quickly got ahead of the truck. Anna put her top back on and went to sleep soon after, dozing in the sun. Almost an hour later I pulled off the highway into a gas station that doubled as a truck stop. I parked on the side, across from the line of semis. I had to make a few phone calls, so I went around front and Anna stayed in the Jeep. My calls were over in a few minutes, and I came back to the Jeep, but Anna was not there. Where I was standing I would have seen her come into the place to use the bathroom, so I scanned the parking lot, thinking she had decided to stretch her legs.
