Ron Thompson and his wife Lyn had completed about half of their long trip to pick up their daughter Suzy from San Francisco. In the back seat sat their 18-year-old son Steve who was occupying himself reading a book. Ron was driving and Lyn was doing the navigating. As Steve could neither drive nor navigate it had been decided that the only part he would play in the journey would be to provide some company for his parents.
Driving such a long distance wouldn't prove much of a problem for Ron as he owned his own haulage company and still drove a truck for long trips from time to time. Lyn had agreed to take the wheel when Ron got tired and needed a break. Having agreed to this Ron knew that his wife couldn't drive very far without getting tired, so he had resigned himself to the fact that he would be spending long hours behind the wheel.
Ron and Lyn had been married twenty years and were very happy. At 54 years old, 18 years older than his wife, Ron was still quite fit. Lyn was, and always had been, a very sexually active woman. Over the past few months, however, Ron had found it increasingly difficult to keep up with his wife's sexual needs and had not been able to make love to her as often as she wanted. Lyn had always had the need to masturbate on a regular basis, even when Ron was still giving it to her every night, but now that it was down to two or three times a week strumming her clit was a twice daily habit.
Lyn had been sat in the front of the car navigating for a long while now and as the better part of the next part of the journey consisted of mainly straight road, navigation wasn't really necessary and she found her eyes growing heavy with tiredness.
Steve was not much company at all whilst reading his book so as Lyn began to fall asleep her husband became more and more annoyed. Ron had expected to take the lion's share of the driving, but had hoped that the other two would at least provide some company.
Ron shook his wife and said in a rather abrupt tone, "If you're going to have a kip why don't you get in the back with Steve, at least I wont have to listen to you snoring."
Lyn groaned at Ron's nagging voice and unbuckled herself from the seat. Turning over onto her knees she slid over the top of the seat and into the back of the car headfirst. Ron was annoyed at this as Lyn was wearing her usual short skirt and her gorgeous tanned legs were suddenly on show to her son, sat behind him, as she clambered awkwardly over the seat.
"Hey Mom," said Steve as she flopped into the seat next to him.
Lyn, still half asleep, just murmured something inaudible back at him and laid her head down next to him, falling back into her slumber straight away.
As the time passed Ron drove on, listening to some old tunes on the radio and thinking about lots of different things but nothing much in general. In the back seat Lyn had, in her sleep, turned over and laid her head in her son's lap. Steve had put his book down and had now nodded off himself. Ron thought to himself that he would carry on driving until they were getting low on fuel and then make a stop.
After a short while Lyn blinked her eyes open and came around from her kip. Her head was still laid in her son's lap and it took a few fleeting seconds for her to realise where she was. As her mind, along with her eyes, became clear she could feel that the side of her face was resting on the top of her son's waist and that the zip of his jeans was straining to hold in what appeared to be a very sizeable hard on.
Right there in front of her eyes was a large, hard cock straining at the leash to push itself to freedom. Lyn realised that her son was still fast asleep and that his hard cock was the result of some gentle rubbing from her face as they both slept. Lyn didn't move as she didn't want to wake her son but she also didn't want her husband to realise the situation.
Ron could not see directly behind himself, even in the mirror, so he was ignorant of the state of things happening in the back seat. Glancing at the fuel gauge in front of him he saw that the tank was now half empty so the journey could carry on for a while yet, before he would have to stop.
In the back seat Lyn had begun to get very horny at the thought of the hard cock meat, behind the zip, in front of her eyes. She moved her left hand down and slid it up slowly between her thighs as if doing so in her sleep. Reaching her panties she felt her already wet pussy squeezing hot juice through them against her hand, her hard clit pushing out of its hood to strain for attention.
Ron glanced in the mirror as he saw his wife move but didn't notice anything unusual and quickly went back to the road ahead. Barry White sung Just The Way You Are to him from the radio and his mind returned to times gone by whilst he hummed along to the tune.
The naughty mother in the back seat had resigned herself to the fact that even though it was her son she was with, she had to at least see that cock in front of her. Close to her orgasm already from her hand rubbing the front of her panties, she slowly moved the other one up to the zipper of her son's jeans. Being aware, as she was, of her husband not a metre in front of her made what she was doing all the more exciting. Her hand trembled slightly as she took the zip handle between her fingers and pulled it down slowly.
Lyn nearly jumped back as Steve's steel hard cock sprung through the opening in his jeans and pointed its large, shiny mushroom head straight at her face. Steve made a slight murmur as he began to come out of his sleep slightly at the feel of the open air on his cock. Lyn stared open mouthed at the wondrous sight of her son's delicious cock inches from her face, dribbling pre-cum onto his jeans.
Ron could hear faint sounds of movement in the back and said quietly, turning his head to the side, "Is someone awake back there?"
