As the summer progressed the family continued their sexual dalliances. It was the perfect situation for exploiting the naughty fun of inter-familial sex. Nobody was innocent. Rob was intimate with his wife Sandy, but his real fantasy object was his daughter Diane, who teased him mercilessly, and who graced him with the occasional blowjob if the opportunity came up. Chris continued to be most fascinated with his mother's body but he periodically messed around with his sister. And Diane, well, she was able to take as she pleased. She was the only one aware of all the convoluted sexual connections in the household and she loved the power that came with that knowledge. In a sense she was the impresario of the incestuous relations. She loved to keep tabs on all of the illicit relations and if she got bored she would even take steps to instigate sex between her family members if she had nothing else to do at the time.
So the summer progressed splendidly and the family's collective libido was constantly stimulated. Externally they appeared to be a perfectly normal, attractive midwestern family. But beneath the placid exterior there was a storm of sexual pleasure, as they exploited the usually platonic family roles for deviant purposes.
Yet, summers like this one pass too quickly, and in what seemed like a blink of an eye, Sandy realized Chris would be returning to the East in just 10 days. Diane would also be starting a new semester, and with Chris gone, she would go back to spending most of her time on campus. As much as Sandy was anxious about the stability of her family in light of her affair with her children, she knew she would be sad when it ended.
Even more than the mindblowing sex, Sandy loved the togetherness of their adult family. She knew it was a rare thing for children to grow up and maintain familial harmony into adulthood. She relished the time they spent together and the wonderful dynamic they could establish.
These thoughts inspired Sandy to plan a camping trip together. They all loved the outdoors, and it would give them a chance to be together one last extended time before summer slipped away from them. She was sure her family would agree.
When she broached the subject that evening at dinner, Rob and Diane were more excited about the idea than Chris. It dawned on Sandy that he was filled with regret about losing sexual access to her. He knew they would likely not be able to be intimate if the four of them were together for the whole week, and it was obviously weighing on his mind. It made her swell with pride to realize how important she had become to her hunk of a son. And she made a mental note to spend some extra special time with him before they left.
The next day she found Chris reading with his shirt off outside, enjoying the mellow sun of the morning, before it became too hot. She stood behind him for a moment before announcing her presence, taking in the sight of his tanned and rippling physique. The way he wore his glasses and seemed so absorbed by his book made him even more attractive, she thought. Not just a hunk of meat, she thought. But a hunk of meat nonetheless. She smiled as she felt herself becoming wet and allowed thoughts of their coupling slip into her mind. She was tempted to reach down and stroke herself, before realizing she was outside for the whole neighborhood to see. But then her eyes focused on the bulge in Chris' pants and a thrill raced up her spine. Screw the neighborhood! Just to indulge the perversity of the idea, she slipped her handed into her shorts and dipped a finger into her moist slit. It felt wonderful, and she dallied a bit before strumming her clit briefly, and then reluctantly removing her hand. What a hussy I am, she thought, and the thought thrilled her.
Approaching Chris, she put her arms on his broad shoulders and lovingly massaged his muscles. He put down the book and leaned back, relaxing into her touch.
"I'm headed to the store to get camping stuff. Wanna come?" she asked.
Chris opened his eyes then and looked up. He could see her breasts at the top of his field of vision. He could tell quite clearly from her elongated nipples that she was aroused. Parsing her words, he mused about how he'd much rather come than go to the camping store. But knowing his randy mother he wondered if they might find some way to do both. Plus, he liked spending time with her, and shopping at the camping store was better than just ordinary shopping.
"Mmmm," he moaned, expressing his feelings of laziness in the warm sun and the pleasure of her casual massage. "Sure. I gotta go grab a shirt though."
As he rose from the chair he brushed by her, allowing his semi-stiff rod to trace along her hips. They moved around each other like lovers, exploiting any opportunity for the odd touch or expression of affection. Luckily the neighborhood was pretty well empty on this weekday morning, and their subtle touches went unnoticed to all but themselves. Rubbing his hand across her lower back and butt, Chris lingered just a bit before moving along inside to put on something decent for shopping.
As he re-emerged outside, Sandy tossed him the keys. Chris usually let his mother drive. He didn't mind driving, but he wasn't in the habit since he'd moved out east. And he wasn't the type of guy who needed to be in control of everything. But he didn't question. He caught the keys smoothly and started for the car.
Chris was actually enjoying it. The roads were pretty empty and he was feeling the same thrill of a kid at a go-cart race – enjoying the power of the engine beneath him as he shifted gears. After such a long time without driving, even the subdued pace of the suburban streets was entertaining.
Distracted by the activity, Chris' mind was, for once, not concerned with his sexy mother. Perhaps Sandy noticed this and wanted to regain her sexual control over her son. Or perhaps she had planned all along. But, in any event, she slowly moved her hand to his lap and drew down the zipper on his khaki shorts. Before taking his penis out of the fly, she put her palm down on his lap. She enjoyed feeling his cock beneath the fabric as it firmed, complicating the movements of his powerful legs against the pedals. But before his cock was fully engorged she had deftly slipped it through his boxers and fly and was slowly stroking it. It was, as always, beautiful to her eyes. It looked so powerful, even angry, in its rigidity, but it was soft to the touch, especially the almost velvety feel of the light purple head as she moved her cool palm and fingers over and around him.
Sandy knew exactly how to manipulate him. Almost as if it were her own, she knew where to teasingly touch to ratchet her son's pleasure steadily upward. She wasn't jerking him off. She was just toying with him, touching him gently in all the right places as he distractedly managed his way through the labyrinthine streets. She noticed he drove right at the speed limit, apparently not in any hurry at all to get to the store.
But it was not a long trip, and as they pulled up in front Sandy withdrew her hand. She would have tried to put away his pecker, but she wasn't skilled enough in the arts of manhood to stuff that rod back into his clothing. She was always amazed that men could do so, as cocks seemed so huge and present when turgid and so blithely absent from view in normal day life.
Chris seemed disappointed to have to put himself away and go shopping. But he knew his mother wouldn't leave him in a lurch for too long. And if his skills of detection were correct, she was quite aroused in her own right. So he did the best he could to restrain his cock from public view and followed him mom into the store, focusing squarely on her twitching ass as he walked.
They needed a few sleeping bags and a propane stove, but Sandy was in no hurry. She liked browsing the selection with her aroused son at her side. She could feel his gaze on her body as she walked slowly around, and it thrilled her. She pretended to look at various camping implements but a great deal of her attention was on her son, whose presence at her side weighed heavily on her mind. As a result there was more than a few subtle contacts between them. As they turned a corner she would let her breasts graze his arm or back. And once as they moved behind a rack of clothing in the corner of the store, she even went so far as the grasp his crotch briefly with her hand. She was satisfied to feel that it was still semi-rigid.
As they found the sleeping bag display a salesgirl noticed and came over to offer assistance. Sandy took notice of her cute, youthful face, and straight brown hair drawn back into a ponytail. The girl's tits were fantastic. Even through the red vest she wore it was obvious that they were full, yet still perky with youth. They seemed to almost leap away from her chest as she approached. She also wore short khaki shorts and her tanned legs were absolutely perfect. Simply put, this girl was stunning.
"Can I help you?" she asked, directing her question at Chris instead of Sandy and angling her body in a way that indicated interest in something more than just a sale.
Chris flashed a winning smile and met her gaze confidently. "We're in the market for some sleeping bags." As he paused Sandy noticed her son's calm confidence and reflected on how attractive he must have seemed even to the gorgeous salesclerk, who was probably about 4 years younger than her son. "Any suggestions?" Chris finished.
