His climax burst inside her cunt with nearly as much violent power as his first come, when she had been perched atop the counter in the kitchen. Once more Marie realized just how lucky she was to have a durable, resilient lover like her son – what a contrast to the lazy-pricked Paul Ryan! Mike pumped his cock hard into her waiting cunt and then began to come, shooting those incredibly intense spurts of hot cum that turned her into storm center of sexual wonder. Her jangled nerves quickly answered his climax with a terrifically pleasing response all their own; she felt the knot of sexual excitement which had built up within her belly evaporate with a quickness that left her limp with satisfaction. Mike continued pumping his cock into her cunt for another moment, then keeled over at her side, limp and exhausted.
That put their relationship back onto an even keel, where it remained for the next four weeks, or until the end of the school year. Scarcely had Marie congratulated herself on her good fortune in getting her son back into her bed, however, than she began worrying about what she would do during the summer. Mike expected to resume the job he had had the summer before – life-guarding at Lakewood Hills, a privately owned lake resort in the hills twenty miles north of their city.
He would be spending five or six nights a week at the resort, Marie knew, and this would drastically curtail the amount of time they had for such marvelous activities as fucking and sucking. She could not ask him to give up the job, but neither could she readily contemplate long periods of time during which she would have no access to his big prick.
She seized upon a newspaper account of a local burglary to initiate a plan which had slowly been taking shape within her mind for several days. After reading the story to him one evening, she mentioned her fear of being alone in the small house they shared, and expressed an interest in getting a guard dog. Mike replied that he thought this was a very good idea, and Marie smiled victoriously. She had never been able to obliterate the memory of that girl in the movie, the one who had teased the Great Dane into fucking her so frantically, and the more she remembered that furiously exciting scene, the more she wondered if perhaps a dog might not be the perfect solution to her problems when Mike left for his summer job. Surely almost any dog would be a more satisfactory lover than Paul Ryan, as well as considerably more discreet, and on the occasions when Mike returned home, well, he would not have to know about it. She began searching the local kennels the next day and soon acquired a sixteen-month-old German Shepherd, a male who was fully grown but still playful enough to be a lot of fun as well. She brought the dog home the week before Mike left for his summer job.
Ranger, as they called the new dog, proved to be a perfect delight. He was already house-broken and quickly showed that he had a powerful bark when anyone except Mike or Marie approached the house. With them, he was the soul of gentleness, but when strangers approached, he gave every indication of being a frighteningly effective watchdog. Marie could not fully investigate the beast's sexual potential until Mike left, but she took advantage of the few opportunities available to her and checked him out as best she could.
She remembered seeing the girl in the movie and the way she had manipulated the Great Dane's cock until it was rigid and dripping with frantic life. This memory was enough, and she spent a very exciting fifteen minutes one afternoon playing with Ranger's prick. The dog rolled over onto his back when she grasped the furry sheath hiding his cock; she worked it back and forth a few times and found that he could get a hard-on as quickly as her son. The sight of his prick, so pink and so much resembling a big carrot, brought her pussy to a quick boil and she could very easily have had her first fuck with the animal then and there had she not heard Mike driving up in their car. She quickly moved away from the poor dog, who whimpered piteously when she took her hand away from his cock, and was in the living room when her son entered the house.
That brief, tantalizing sight of Ranger's cock was enough to set Marie's mind somewhat more at ease about the lonely nights ahead during the summer. The dog's prick looked to be large enough to give her a considerable amount of sexual pleasure, though she suspected that Ranger would never be a really satisfactory substitute for young Mike. She put the dog out of her mind and turned her attention to satisfying her son's lusty appetites, a much more delightful task; he had come in with another of those jeans-splitting hard-ons, and gave every indication of trying to overwhelm her with sheer masculine power.
Marie's campaign to introduce her son to the joys of muff-diving did not progress satisfactorily in the few weeks they had left before summer vacation. She taught him to nuzzle her boobs, and he learned to use his lips on the upper part of her belly. But whenever she tried to gently push his head farther down her body, she found a silent but stubborn resistance. She did not feel sure enough of herself to ask him outright for the kiss that he desired most of all; there were times when she could almost make herself come simply by imagining his sweet, tender young mouth lapping her pussy's overheated flesh. The ferocity of her desire, and the savage way he answered that desire when he shoved his big cock into her cunt, helped compensate for her failure to turn him into a pussy-muncher. Even without that added delight, she found, he was easily his father's equal when it came to fucking, as they so often did when they were alone in the house together.
Mike proved quite willing to talk at length about his conquests among his high-school classmates. He had fucked four girls, he said, and Marie was quite astonished to learn their identities. They were all perfect flowers of youthful innocence, she had always believed, but Mike told her that only one of them had been a virgin when he had slipped his enormous cock into their cunts. Two of them, Angie Wellon and Julie Masters, had been so bold as to suck his prick; he said that he had shot off in each of their mouths and that they had expressed great delight in the ferocity with which he had shot his cum into their throats. He also said, and this was the part which most warmed Marie's yearning heart, that none of the four had fucked with anything like the wholehearted zeal which she displayed.
***Marie drove Mike up to the lake to begin his work for the summer. They had spent most of the night trying to store up enough orgiastic pleasure for the weeks ahead, and Mike was very subdued during the drive. He gave his mother a fond kiss when she pulled up in front of the building where he would stay; it was not the kind of farewell she would have liked, but under the circumstances it was the best she could hope for. She watched him lift his suitcase out of the back seat, waved and drove off. The further she got from the camp, curiously enough, the more she looked forward to returning home. The thought of having the house to herself and the assurance of plenty of free time in which to explore Ranger's sexual potential aroused a new interest in her, and she began looking forward to the experiment with more and more enthusiasm.
The dog had been chained up in the back yard. He greeted her with leaping yelps of delight; he had already become the favored member of the family and enjoyed his role. She led him into the house and rubbed his big head fondly until he quieted down. Then she took Ranger into the living room, where she pulled a footstool around into a position which appeared likely. Ranger watched with sparkling eyes, almost as if he could tell that something was afoot which he would like a great deal. Marie lifted her dress and pulled off her panties; during the drive back from the lake, she had become excited enough to have wetted the garment thoroughly. She dangled her panties in front of Ranger's nose to see if he recognized the scent of a woman in heat.
