I picked Debbie up just after 9 on the Saturday morning. It was already hot and I was curious what she would have chosen as 'appropriate' clothing. I was in shirt and trousers, jacket and tie in the back in case needed for the evening.
I was not disappointed, she had gone for a shortish pencil skirt in grey with a matching jacket and a white, quite sheer blouse. She was also clearly wearing stockings I noticed approvingly as she bent to pick up her case to put in the back of the car. We had obviously both been thinking about the hotel bar and the coming evening. She got into the already roasting car alongside me and undid the button on her jacket. She grinned and squiggled down in her seat remarking on the heat and flapping her jacket open, I admired the outline of her well filled bra under the sheer blouse. She saw my look and we both grinned again. I handed her a bottle of water and told her to drink. She undid the top of the bottle and did as she was told, I turned the aircon up a bit and we set off.
The first destination was nearly an hour away, we chatted a bit and the heat started to build up again. Debbie remarked on it and I suggested she take off her jacket. She did so and twisted around in her seat to hang it up in the back. As she did I got a great view of her bra through the blouse. It was white and laced and again quite sheer, I could clearly make out the dark shadow of her nipples through it. again she noticed my look and smiled, the nipples clearly also hardening under the flimsy material. She settled back in her seat and finished her water, I passed her another and told her to take off her blouse. She looked at me halfway through twisting the top off the water, twisted it shut again and put it carefully in the door pocket. She slowly pulled the blouse out of the skirt, then unbuttoned the front. She carefully undid the cuffs and finally slid out of it, again twisting round to put it neatly in the back. The nipples were clearly visible now and already tight and straining at the lace. She settled back down and began on the new bottle of water.
We were on the dual carriageway now making a good pace with only light traffic, we overtook a short convoy of trucks, at least one driver noticed Debbie as we sped past. She giggled and waved back. She finished the water and looked across at me, cupping her breasts through the bra giving the nipples a tweak with thumb and forefinger. I smiled and had to force myself to keep looking at the road. I took a deep breath and told her to take off her bra and panties. She gasped a little and hesitated, then told me she wasn't wearing any panties. She slowly bent forward and reached behind her unclipping the bra and slipping out of it. we were passing more trucks and she kept her arms crossed in front of her. I told her to sit up straight and put them by her sides. She did so breasts quivering with the movement of the car, nipples tight and puckered. We swung out to pass a white van, the driver looked out at us as we passed and almost swerved into us! We both laughed and I told her she'd better put her blouse back on.
We were approaching the first town so she tidied up and we got ready to park. I gave her a third bottle of water to sip as we worked. It took about half an hour, then we made our way back to the car. As we got back in she told me she needed to pee. I told her to hang on to it. We had a long run coming up. We pulled out of the town and moved back onto the main road, I asked how urgent it was, she told me it wasn't too bad yet. The traffic was very light now, I told her to hitch her skirt up and show me the tops of her stockings. She did and more, giving me a good glimpse of her trimmed strip disappearing between her thighs. I told her to spread her legs and start to masturbate for me. She sighed like she'd been waiting for this, settled down into her seat put her head back and started. She quickly settled into a rhythm and judging from the little noises was already very wet. she grunted and shifted in her seat giving herself better access, eyes closed and gently biting her bottom lip. I told her to let me know when she was getting close.
