It was the summer after my highschool/college girlfriend Patty dumped me, I was home from college with little to do and all day to do it. I was working at my dad's auto shop, for spending money. I enjoyed the work and was pretty good at it, I still am.
Over the fourth of July holiday, my dad's business partner was taking his race car to Beech Bend raceway and asked if I wanted to tag along. I jumped at the chance. I already had a serious need for speed and this might take my mind off my girl problems.
I met him at his house early one morning and we set out for Bowling Green, me, Tony, my dad's partner, Mary, his wife and their two bratty daughters. Tony's brother would meet us there, he was the driver, Tony was the mechanic.
We set off in Tony's 4 door truck, with the race car, on a trailer, behind us.
We made Beech Bend by noon and set up camp in the racer's area. Tony had a slide-in camper in the truck for his family, Tony's brother, Kenny, would tent camp with his wife. I would sleep in the cab of the truck. Not glamorous, but I wasn't complaining.
I spent the rest of the day at the amusement park there. The racing started the next day, so I wasn't needed.
We were up bright and early the next day and prepped the car.
Tony was in a foul mood. He and Mary had been fighting since we got here, she was something of a diva and didn't want to be there. Tony had told her she could stay home, but she insisted on coming anyway, go figure.
We won our first race easily. We managed to win our second race too, barely. Unfortunately, we hurt the car and couldn't fix it. We had to forfeit.
Tony and Kenny were despondent and spent the rest of the day getting shit-faced drunk.
I spent the time helping Mary with the kids and generally staying out of Tony's way, he was a notoriously mean drunk.
As soon as it was dark, I retired to the truck cab to try to get some sleep.
Not long afterwards, I heard one helluva ruckus coming from the camper above me. I couldn't make out any words, but the voices were angry. A slamming door ended the fracas, and silence returned.
I rolled over and attempted to go to sleep. Some time later, one of the back doors opened, and somebody got in.
I sat up and peered over the seat to see who was there. It was Mary.
"Sorry, I didn't mean to wake you." She lamented. "Is it OK if I sleep here?" "Tony came in drunk off his ass and horny, I'm not letting that drunk bastard touch me."
"Sure." I said. "After all, it is technically your truck."
She smiled. "Thanks, I can't go back there right now."
I handed her my extra blanket and went back to sleep.
I awoke later, I thought I heard something. As I strained to listen I heard it again, a low, soft, almost moaning sound. It took me several minutes to realize it was coming from the back seat.
I just figured it was Mary, snoring, or something to that effect, but decided to peek over the seat to see.
Boy, was I wrong. In the moonlight that filtered in I could see her, naked, on her back with one hand on her left tit and the other buried in her snatch.
She was rapidly propelling herself towards orgasm, and was trying, rather ineffectively, to do so quietly.
It was about then I heard the wet noises coming from her pussy as she played with herself. I sat, transfixed, watching her. I didn't even care if she saw me, after all, she knew I was here.
It wasn't long before she saw me. She gasped and attempted to cover up. "Shit!" She hissed. "I though you were asleep."
"I was." I grinned. "You woke me up."
