Summer Trip Mary and I were driving to her parents house one bright Saturday afternoon last summer, a trip of about one-and-a-half hours. We picked up a six pack of beer before we left, and had drunk most of it about half way into the trip. Mary was feeling pretty frisky, and decided to ride the rest of the way topless. She whisked off her halter top, and rode beside me in just her very short pants. Naturally, this brought a rise from me...my hard cock grew to the point where it was straining against my shorts as I drove. Mary was just lounging in the passenger seat, enjoying a beer, enjoying the sun, enjoying flashing the occasional passing trucker, and enjoying my predicament. After finishing the last beer, Mary decided she was still thirsty, but she had to stop at a bathroom first. There was a gas station coming up shortly, and we needed to get some gas anyway, so we stopped. Mary slipped back into her halter top and headed for the bathroom while I filled up the car. She went into the office to get the key, and then disappeared into the bathroom for a minute. After dropping off the key, she bounced back to the car and got in. I went in to pay for the gas with a credit card, and as the attendant was ringing up the purchase, I noticed that there was a cooler full of beer available for sale. Since I hadn't brought any money in with me, I headed back out to the car to get some cash. Mary smiled at me when I returned, and I could see two very hard nipples poking out at me through the material of her top. "Why the funny look?" I asked. "Well, did you get a good look at the attendant in there?" she giggled. I said no. "He's got a very hot bod," she said, "and the bulge in his pants got much bigger between the time I got the key and the time I dropped it off." I smiled as an idea appeared. "Look Mary, we are out here in the middle of nowhere and nobody else is around...why not give the guy a thrill. Go buy the beer and 'accidentally' fall out of your top when you're in there." She smiled and said, "I've got a better idea!" She looked a bit nervous as she checked the road for both directions. After seeing no one coming for as far as the eye could see, she slipped out of her top and her shorts, leaving her with just her tennis shoes and a smile. "Watch this," she said as she gathered up some money and stepped out of the car. She ran into the office nude to get the beer! The attendant was working at something on the desk until she opened the door, and then did a classic double take. I could see a huge grin appear as Mary got a six-pack from the cooler and set it on the desk. They were both wearing smiles as he rang up the beer and she ran out. She hopped in the car and said "Let's go!" Waving to the attendant as we pulled out, I could see that her nipples were harder than I had ever seen them. Also, my cock was throbbing harder than I could remember. "What did you think of that," she said, as she opened another beer and leaned back to sip it. "I think that poor guy is going to have to close the station so he can beat off," was my reply. She smiled as she leaned over and unzipped my pants. "We're going to be at my parents house in 30 minutes," she said. "Think you can come in my mouth by then?" "You bet!" I replied. Mary proceeded to give me one of the most satisfying blow jobs of my life as we drove down the empty road...her nude and me with my shorts around my knees. Even though she sucked on me till I shot deep into her throat, the experience left me with a hard-on for two more hours. Needless to say that was a bit embarrasing when we got to her parents house.
