Snapping her eyes shut completely, Marie let the billows of color that were breaking against the shores of her brain intensify and increase in their magnitude. Soft greens turned to raging reds as her body soared higher and higher through the maze of sensation. Marie was only vaguely conscious of the trails of sweat that were running freely from her forehead and down her face as the flush of sexual delight crept across her cheeks and spread like a measles rash across her chest and buttocks.
These physical reactions, however, were not lost on Suzanne, and she sucked at her mother's breast harder than ever. Her own need to reach a climax was growing more fierce and she was happy that her mother had finally gone over the top and would now be less demanding of her. In fact, Suzanne knew that her mother would try to bring her to her own completion as soon as she recovered her composure.
Letting her mother's tit slide from between her sucking lips, she concentrated on getting the most sensation possible from Robert's tongue. Back and forth her hips thrust, letting his tongue ripple over the tiny bud of flesh that was the center of her womanhood. Her hands still held her cunt lips apart and she started moving them to heighten the ecstasy. Her mother rolled her body to the side, letting Robert's still hard flesh slip sloppily from the slash that marked her cunt. Suzanne looked down at the still rigid pole, its length thickly coated with the juices from her mother's body.
As Marie moved away, Suzanne dropped her hands from her own crotch and let them curl around Robert's prick to hold it softly. She pulled at the flesh and watched in a wild fascination as the head swelled and changed color. Leaning over at an acute angle, she licked at the wetness of the head, letting her tongue pass back and forth over the tender silky surface. She heard Robert moan softly, the sounds muffled by the close connection between his mouth and her cunt.
With desire born of passion, Suzanne opened her lips and forced her head down so that the entire length of his cock was buried in the hot confines of her mouth. Her lips hollowed as she sucked greedily at the long root that pushed almost to the back of her throat. She wanted him to fill her just like he had filled her mother, and to accomplish this, she now walked quickly forward on her knees so that her crotch was directly over his cock. She had released her mouth's grip on Robert's cock so that she might thrust its length into her body. She was finished getting herself "turned on"; now it was time to fuck, plain and simple fucking.
Without waiting, Suzanne positioned the head of Robert's prick at the entrance of her cunt and slowly started to sink down upon its length. Her tight cunt expanded under the pressure of her weight as she settled on the rod. She knew that she was tighter than her mother and fitted Robert's prick like a smooth glove. Her insides were gorged with the fullness of his prick and she shuddered as she finally hit bottom, filled to the hilt with his meat. Their bodies ground together, Suzanne's buttocks resting hard on the firm muscles of Robert's belly.
Feeling his sister sink down on his cock, Robert pushed his hips upward and felt his cock slide into her tightness. Christ, she was tight, and wet, and juicy! Hell, he knew that he was about to blow his balls and fill his sister's tight cunt with his juices. The head of his cock throbbed mightily, and he rammed it as deeply as he could into her body seeking the center of her being. The feeling was overwhelming and he accepted it as his due… Up and down his hips moved, his buttocks slapping the hardness of the bed. His balls were churning in their wrinkled sack and pumping the life-giving fluid into the tubes that would eventually lead to that warm place right in the center of his sister's body.
Marie watched with the warm pleasure of afterglow as her two children joined their strong bodies together for a final coupling. She sensed that Robert would soon blow his balls in his sister's cunt. That was fine with Marie since she had already gotten the pleasure she needed from the hard rod of flesh that he was so mightily thrusting in and out of his sister; however, she wanted to give her daughter the added pleasure of having her mother's mouth fastened to one of her sensual zones. She stood up to find a place where she could fit into the sexual tableau.
Robert was holding his sister by the waist as he met her downward plunges with upward thrusts of his own. Marie pushed his arms down as she returned to the bed, straddling his body and wrapping her arms around her daughter's supple body, her hands opening and grasping with firmness the large bulging globes of Suzanne's breasts. Marie was facing her daughter's back since the young girl had been too impatient to turn around, but had merely moved forward so that she could ram the shaft of Robert's cock into her body.
Marie rolled the distended tips of Suzanne's nipples between her fingers and moved her hands in a circular fashion to stretch her daughter's tender flesh and pull on the most tender portion of all. Her lips and tongue were making small slick trails over Suzanne's shoulders and back. Marie, knowing how sensitive Suzanne's earlobes were to sexual stimulation, raised her body so that she could play with her daughter's breasts and suck at the little pink shells which were now reddening with heated blood.
The thought of bringing pleasure to her own daughter had always somehow perversely turned Marie on and she increased the pressure of her hands, fingers, and tongue. As she worked to bring still greater pleasure to her young daughter's body, she became aware of the urgent tugs on her waist. Robert was trying to move her body back so that he could bring his mouth to play against the soft hair-covered juncture of her crotch.
Sighing with pleasure that both her children were so orally oriented, Marie moved quickly back on the bed, spreading her legs wide so that her cunt was fully exposed. New and vibrant energy throbbed into her system as she brought her body to the lips that her son was offering for her pleasure. Blood raced through her already supercharged system and made her glow.
Robert, seeking to add new thrills to the mixture, of sucking and fucking, gripped the rounded globes of his mother's tightly stretched rump. Digging in his thumb on either soft globe, he pushed the two twin spheres apart to expose the tight little ring of her anus. He had never done this before, and he didn't know whether or not his mother had ever done it, but with her experience it seemed to him likely that she had. It didn't matter whether she had or not, since she was going to have his hard tongue shoved into her rectum and she could like it or not.
With this thought foremost in his mind, Robert lifted his head and licked at the lowest portion of his mother's cunt, letting the tip insert itself into the slopping channel of her sex and drawing the juices that her body was oozing down toward her asshole. Pushing harder with his thumbs, he pushed the cheeks of her ass even further apart and then when she was opened to his attack like a book, he made his move. It was subtle at first, just a brush and lick, but the reaction was instantaneous. He felt Marie's body stiffen and then relax as his tongue lapped across the wrinkled ring of flesh. Pointing his tongue's tip like a dagger point, Robert took aim as best he could without being able to see his target and stabbed forward. His tongue hit dead center, and he lifted his head, straining his powerful neck muscles with the effort of his upward plunge. His mother's body stiffened and then rose high off the bed in an unsuccessful effort to escape the hot wet tongue blade that sought an entrance to her rear hole. Robert felt the resistance of the puckered ring, but continued to push at the entrance with the tip of his tongue. Slowly, almost imperceptibly at first, the tight ring gave way under his insistent pressure.
