I was driving along the highway to the arranged spot to where Marg was waiting. I could not help but think all the way there of what we planned. Marg had always fantasized of having a break down on the road and having a trucker pick her up and take her to a garage and here I was, about to make her fantasy become a reality.
Marg first got ready by dressing the way she fantasizes she is dressed for when he picks her up on the side of the road. She applies her make up liberally though instead of her normal mauve lipstick and nail polish, she applies her candy apple red with hi gloss. This goes well with the rest of her outfit consisting of black heels, stockings with seams up the back attaching to her sheer black strapless merry widow corset with demi-bra. No panties this time, as it would show lines through her tight fitted, slightly sheer and lacy dress with spaghetti straps and almost translucent from the hem just above her knees up to the tops of her thighs. Standing in the light of the day this outfit, though covering her body, the light shining on her would make her rather large 36D breasts and long legs of her 5'8" in her heels very easily noticed for anyone that happens to look.
I looked ahead and could see her standing by her car. The trunk up and she was leaning in searching for her spare and jack. There was a car there with a couple people returning to it, from what I could tell she had just told them that she'd be ok. I put on my flasher and pulled up behind her as they drove off. I jumped down from my truck and made my way over to her. She stood and faced me. I could see through her dress as if it where a sheer stocking and I thought for a moment what those guys must also have seen when they stopped. Her nipples were straining against the thin material of her dress and the tops of her stockings in clear view backlit from the sun. The unexpected stopping of the other car as it turned out was a bonus for me as I could feel my cock in my pants stiffen from the thought of what they say, what I am seeing now.
I asked her if I could be of assistance and she accepted, saying that she had a flat and could use some help getting her tire changed. I looked into the trunk and told her that the spare was flat and there was nothing I could do other then give her a ride to the next town where she could get a tow truck to pick up her car and repair it at a local garage. She accepted and we locked up her car and I helped her up into the cab of my truck. As I steadied her up into the cab I could not help but notice when her long leg stepped into the cab that under her dress she wore no panties. I could easily make out her well-trimmed bush, the same auburn color as her short hair on her head. It was trimmed very short and cleanly shaven around her lips and straight across from the top of her lips where her nice sized clit was. This was the finest pussy that I have seen in a long time, it being on a woman that seemed to be in her mid-fifties was even more of a bonus as I have always had a thing for women older then myself. My guess of mid-fifties would make her a good fifteen or sixteen years my senior, however she had a fantastic body. My measuring her up quickly would put her at about 130 lbs, at least 5'7" or 5'8" tall in those heels and her breasts had to be at least 36C or D. My cock was so stiff, I had to adjust it as I came around the truck to get in on my side so as that she would not notice my hard on. I climbed in and settled into my seat, fired up the truck and pulled off.
We were driving for about 20 minutes chatting as we drove more for me in my mind for a reason to keep looking over at her sitting in the seat next to me. Looking at her long shapely legs in her black silk stockings and heels. Seeing the lacy tops of the stockings through the thin material of her dress and her shapely breasts and perky nipples backlit from the sunlight coming through her window. This was more then enough to keep my hardened cock pressing against my trousers making them noticeably tent if she were to look down as I have noticed her do from time to time.
