The big Cat groaned as it dug into the hillside with its sharp scraper blade, crisscrossing the side of the hill like a bright yellow prehistoric spider taking tons of dirt into its gaping maw with each pass. Katie Arden operated the huge piece of equipment with the skill of a surgeon, deftly maneuvering the big earth mover like it was the family car. At first the other operators were skeptical of her ability to handle one of the big rigs, but grudgingly they had to admit that she could do the job as well, if not better than most them! While it had taken awhile, she was now pretty much considered one of the "guys", and was usually included in the horseplay and joking around that came with the territory. From the time she was a little girl Katie had been fascinated with heavy equipment. Much to the chagrin of her parents, she ignored the usual feminine pursuits, and as soon as she graduated from high school she enrolled in a heavy equipment operator's school. Six months later she had her union card and was driving a packer on a new highway just outside of her home town. It was during her time in heavy equipment school that Katie made a startling if not pleasant discovery, the constant vibration that hummed from the motor all the way up to the cab could induce orgasms in her vagina if she held her cunt in the right position of the seat! The first time it happened, she barely was able to keep control of her tractor! As she became more familiar with the equipment, it was easy for her to have as many as three or four climaxes a day by shifting her vagina so her clit could get the maximum effect of the vibrating motor!!!

Katie always was highly sexed, and her mother wondered if that had anything to do with her wanting to do such a masculine job!!! Well Katie was definitely all woman, with a very voluptuous body that even under her work clothes was hard to hide. Ever since she could remember she always loved touching her private parts, whether it be her large firm breasts or her pouty lipped vagina, it really made no difference. By age eighteen she was regularly having orgasms by rubbing her little clit with her finger, and on several occasions her mother happened to catch her doing the nasty, but no amount of scolding could make her stop pleasuring herself! Her mother finally threw up her hands and gave up, realizing that her daughter was very highly sexed, and needed constant sexual relief. She had to admit that she was secretly proud, because she herself was an early masturbater, and to see her daughter following in her footsteps was good for her soul! When she told her husband Rick that their daughter was doing a lot of "exploring", he just laughed and said, "Like mother like daughter," and then proceeded to fuck her for the fourth time that week!!! While her husband was pounding his big cock into her hot cunt, she thought of how cute her daughter's 18 year old pussy had looked when she saw her fingers disappearing inside of her tight little cunt! Her own orgasm poured over her thinking about how lucky her daughter was to have such a needy vagina!
