Lyn sat directly opposite her husband in the service area cafΓ©. Her mind was neither on him or the food in front of her. All she could think about was her son Steve's hand on her thigh, under the table, as he sat next to her. Why? She asked herself, did he turn her on so much and so easily? It wasn't that she didn't love her husband any more, and it wasn't that he didn't even turn her on anymore. It seemed, she reasoned to herself, that although her relationship with Ron hadn't changed she had.
Ron chatted to his wife and son about nothing much really, he just needed some conversation after driving so far essentially on his own. Lyn and Steve, so he thought, had been asleep for ages and he had driven most of the journey listening to the radio. Tucking into the food in front of him he had no idea of what was going on opposite him, under the table.
Steve's hand rubbed steadily up and down his mother's inner thigh. He had never known himself be so turned on before. Since waking up in the back of the car with his hard cock in his mother's mouth, he had been almost continuously aroused. His cock was so hard now that it throbbed and ached and yet not 15 minutes ago it was spurting it's second massive orgasm all over his writhing mother's pussy. Unlike Lyn he wasn't questioning himself, he just felt like the luckiest boy in the world. Steve felt like his aching cock would be rock hard as long as he was with his incredibly sexy mother. It didn't matter one bit that his dad was not even 2 feet away, in fact it only added to the stimulation that he could rub up his mum without him knowing.
Lyn couldn't believe how she could still be so horny after cumming so hard such a short time ago. Glancing up from the table she looked over at the only other people in the cafΓ©. Her heart almost stopped as she realised that the old couple sat by the door could see exactly what was going on between her and her son. It took a few moments of stunning panic to make her suddenly aware that the couple didn't know them, so how could they know that it was her son that was so expertly feeling her up? The warm glow in her stomach returned to rid her of the butterflies that had just been there, as the old man smiled and winked at her.
Ron had his back to the old couple so therefore was still oblivious to anything out of the ordinary. "So who's driving the next bit, me or you?" he asked his wife.
"What?" a stunned Lyn replied.
"Well you did say you'd drive some of the way, didn't you?" he asked back.
"I'm still very tired darling," she mewed in reply, hoping he would give in to her as he usually did when she put on her pleadingly innocent voice.
"I'm tired too, you've had plenty of sleep, I can't drive as far as I used to you know that," Ron spat back at her.
Still feeling her son's hand rubbing her leg and making her pussy throb with delight, she ached for more. She wanted to get back in the rear seat with him and continue their dirty incestuous sex play that was turning her on so much. But Ron suddenly added to his statement and helped change her mind a little.
"If you drive for a while I can get in the back and get some sleep myself," he pleaded.
Lyn thought quickly and replied, "Ok but only if Steve sits in the front with me for company."
Not knowing what naughty thoughts his wife was having, Ron answered, "Sure darling that's fine, just as long as I can get some rest, and our son here will keep you awake whilst you drive."
Steve squeezed his mum's thigh, as he couldn't think why she had agreed to drive. Lyn turned her head and smiled at him and knowing that her husband wasn't looking mouthed, "Its ok," to him and added a sensual wink.
Watching and listening to all that was going on, the old man opposite gave Lyn a knowing smile as she glanced back at him, making her heart skip a beat again. Although Lyn didn't realise, the old man was an experienced lecher and had almost guessed what was happening. Suddenly and without warning he pulled the table cloth in front of him back to reveal his wife's open legs and his hand moving steadily in her panties.
Lyn gasped under her breath as she watched the lecherous old man feel up his wife. The old woman threw her head back slowly and groaned almost loud enough to distract Ron. Lyn's tongue automatically slithered out and ran across her pursed lips as she jumped the next stage towards her oncoming orgasm.
Steve could not see the old couple as his dad was in their eye line so he thought that Lyn's reaction was just down to his fondling. Blowing more caution to the wind, Steve moved his hand higher and felt his mum's bald wet pussy lips meet his searching fingers.
"Are you ok darling?" Ron asked, "You look flushed."
"Mmmm, fine dear," she groaned back as the glowing fire in her cunt grew hotter.
The old woman was now staring intently, along with the old man, at Lyn's splayed legs and the hand fiddling about between them. The old man leaned towards his wife and whispered something in her ear, making her obviously cum immediately with shuddering jolts.
Lyn knew she wasn't far off her orgasm now herself as Steve's finger entered her hot channel once more. Looking over at the dirty old couple she saw the old man pull down his zipper and release his hard cock. Lyn made another quiet gasp as she stared at the old man's quite impressive dick.
Ron looked up at his wife and son and frowned. Lyn and Steve both froze in fear as they both thought for an instant that he had realised what they were doing. For what seemed like an eternity Ron sat staring at them both with a really strange look on his face. "Now look you two, I'm paying for this food so the least you can do is eat it," he moaned at them.
A shudder of relief went up Lyn's spine and she let out the long breath she had been holding. She glanced at Steve, who had stopped breathing as well, and saw the shocked look on his young face. Steve suddenly felt in fear of his father discovering them and much to his mum's disappointment he removed his hand from her pussy.
"Are you sure you're ok darling?" Ron questioned his wife again.
Lyn realised that she was so close to an orgasm before Steve had removed his hand that she probably wouldn't have been able to stop herself from screaming out loud. It was obvious that she didn't want to do that, but she needed to cum so much, so she had to get out of there before she jumped on her son right there in front of everyone.
"Um, no I think I need some fresh air," she replied and smoothed down the front of her skirt as she stood.
"Ok babe, we've nearly finished here so don't be long," Ron replied.
