He smiled with trembling lips and kissed her again. His cock continued to slip out until it hung only by the thick, swollen head, now glistening with the slick juices of his cock and her cunt. She tried to relax and savor the new sensation, so long forgotten, of something hot, hard and male sliding out of her. He pulled it nearly all the way out and Mara wondered if her vagina was going to come out with it. Then she felt it sliding smoothly into her, pushing her inner lips apart, spreading her, stretching her, filling her fuller than she had ever been filled before, and yet, strangely enough, unusual as the sensation had become, once she was used to it, it was pleasant, sending tingling thrills throughout all her twisting, trembling loins.
Tim was fucking her with short, steady thrusts, pulling the huge knob of his hot cock nearly out of her cunt lips, until it was just clinging, barely parting the swollen, red folds, then pushing it slowly and steadily back into her, to stretch her right up to the threshold of pain, forcing her quivering clit to rouse and rear and tremble in extreme excitation as it stretched and rubbed along the top-side of his thick shaft. That this tremendously exciting cock should belong to her son was constantly amazing to her. Mike had been big and had taught her how to take the fullness of it easily, she being a small woman. But she had never received one as large as this and it was an experience she could not get used to. The cock thrust in and out, sliding easily, and adding an inch every now and then, easing more and more into her cunt, making the sides cling to it, causing him to gasp as she flexed the muscles deep inside her vagina to caress his huge knob as it began to retreat in a thick, sliding sensation. Mara shifted and settled under him, making herself more comfortable just as she felt him thrust again and-GOD, THERE IT WAS AGAIN, OOOOOOOO-OOHHH! In moving to make herself more comfortable she had let her knees ride outward slightly and Tim, thinking she was preparing for him to invade her more, had driven into her another two inches at least. It filled her, stuffed her-she screamed silently, and then, as she recovered, realized she was rocking upon the pink and swirling sky of pure pleasure as she had not known it for years. Tim slowed down and looked down at his mother. He realized he was gigantic in the sexual department and was afraid he was hurting her. But she smiled at him and pulled his head down to her again, kissing him deeply, passionately and wetly, her tongue driving him wild again. Seeing that he was indeed not hurting her, much at least, he began thumping it into her again, driving the great head of his cock deep, pulling it out, and throwing it into her once more. “Ooooooooooooooooooooohhhhhh, Timmmmy-yyyyyy,” she squealed and rocked her ass up to him in quick lashing thrusts, making him jam his cock more deeply into her. She felt again, darting her fingers between them on his upheave, and felt that he was all the way in when he thrust down. His belly hair was mingling with her cunt hair, and his huge balls were dripping with her cunt-juice, dripping off onto her ass and into the sand. He was grunting and snoring through his nose, slamming his cock into her, until his belly slapped wetly against the balls of her cheeks and her inner thighs. Tim was moving his cock lightly between the frothing lips of her cunt now, making his hips gyrate and twist, his cockhead barely inside her, moving it gently in and out, stretching her all out of shape, stretching the lips of her cunt until she could feel all the hairs twisting and turning and tickling. She had never felt anything so delightful as this, the wonderful cock with the purplish knob moving gently but firmly in and out, teasing her.
Then she gasped, for he was slowly pushing it down into her, slowly spreading the tissues, invading the darkness of her love-tunnel as it had never been invaded before. She cried out with pleasure as the gigantic knob pressed against the hard cone of her cervix and could go no further. She was being fucked to the very innermost depths of her body, and it was almost making her faint with excitement and sensation. It felt so good she just did not know how to picture it-the lovely, delightful sensation of the hot, huge, hard, thick cock that was sliding in and out of her, growing harder now and swelling deep within her. He was panting and she knew he was nearing his climax. In fact, she was beginning to experience small climaxes, one after the other, each growing in intensity. This was her way. When her sensations rose to a certain height, her excitement trembling upon the verge of a huge climax, a series of small ones preceded it, building and spreading throughout her entire body, until the final explosion. It was beginning to boil and stir in her loins and was spreading throughout her entire being. Tim was breathing deeply, his body covered with sweat. He had never felt his cock grow so huge, nor experienced such an exquisite sensation. The knob of his cock tingled as though it were being tickled, each time it reached the downward reach of its stroke. Her tissues clung and milked at his shaft, making him strain to hold back his cum. But he knew it was almost there. She was giving little cries of joy; he could feel surges that lifted her ass to him in violent thrusts, and knew she was getting ready to come, too. He kept it deep inside her, all the way in, as he ground his crotch around in lovely circles until she knew he was tangling their pubic hairs into impossible knots. He had twisted about until he was cupping her swollen, tight breasts in each hand, his thumbs strumming the nipples. Their bodies were so wet with cum-juice and sweat that they squished as they came together and parted. His hot, hard cock began pounding recklessly into her again, driving deep, pulling out, driving back in again, hot, hard and fast, without the kind of gentleness he had heretofore exhibited. She knew that he was getting ready to blast her to the moon! She felt her body respond to this, felt herself once again rising, floating upward to the occasion, her ass rising off the sand in her eagerness to share with him the lovely connection between them-the driving, delicious cock of this boy, her son, was literally driving her out of her mind.
Each time he thrust her ass came up to meet him with a delicious little squish, and each time her ass met his belly his cock plunged fully into her, penetrating her sensitive, swollen, passion-full pussy. Suddenly Mara realized that her huge climax was upon her.
She was engulfed in the throes of an orgasm that made all the others seem like the first she had ever had when she was ten years old and a little boy had rubbed her cunt for her until she jerked and quivered all over. Great surges of pure joy raced through her loins, lifting her, making her strain to thrust her cunt against him and hold it there while she shook and shuddered. “Aaaaaaaaaaaaahhhhhh!” she wailed, her body arched like a bow beneath him. She quivered and shuddered again and again as her coming shook her to the core. Then she felt his cock harden like a steel rod deep inside her. It swelled until she thought she would split and she felt the first hot splash of his cum. He groaned and thrust his cock into her deeper, harder, faster. She heard a thin crying and realized he was at the point of releasing his first cum into the hot, squirming, steaming cunt of a mature woman. Then he moaned and stiffened in her embrace, and she felt his juice dashing in great leaps and spurts, each with the pulse of his cock, shooting great sticky, creamy, thick gobs of cum into her and filling her as an erupting stream fills a dry creek bed.
