As he began to rock above her, now, using short, smooth strokes, her body reacted of its own volition, instinctively; she had surrendered completely to the rippling passion in her, and the mere thought of her unconditional commitment caused further chills of excitement to race the length of her spine as she felt the easy tempo of her brother's turgid length begin to thrust ever long and harder up into her cavern of her moist, throbbing pussy.
As he slowly increased his pace and the length of his stroke, Charity felt her whole body, indeed, her whole being responding to her brother, and she writhed, squirmingly, beneath him. His mouth dropped down to hers, and she thrust her tongue upward between his lips to be sucked, as she moaned, unceasingly, in ecstasy, ready to accept anything, now, that he wanted to do with her. She began to raise her loins up to him in rhythm, countering his driving plunges into her moist depths, and her lovely face contorted in wanton desire, her mouth opening and closing against his lips, her nostrils flaring, her breath beginning to come in short, gasping pants as she became one with him in their illicit, incestuous copulation. It was an abject surrender to the lewd desires of the flesh, even in the face of all ancient taboos.
He could see the perspiration forming on her forehead and between her lusciously firm melon-breasts. Her lovely auburn hair was now in hopeless disarray, and he could see the straining neck muscles, as the mewling sounds of her throat emitted in a constant hum of sound. Christ! She was hot as a three dollar pistol!
… And, Christ… she's my sister! I never really dreamed I'd ever be fucking her!
At that moment, he too gave no heed to right or wrong. He could care less! Charity was his sister, but she was, also, a female whose full, round ass was churning, writhing and bucking, forcing her seething, voracious cunt up against his pillaging cock… a woman, in every sense of the word, who needed to be fucked. Grunting with the effort, he tried to shove even more of his throbbing cock into her.
Damn, what a tight, cute little cunt it was… and what a gorgeous woman his sister was! Christ! The way she was fucking back was driving him right out of his skull!
He slipped his hands down on either side of her and slid them in under the soft, smooth orbs of her slaving ass-cheeks, grasping them hard and brutal in his strong hands, feeling them as they worked, the pliantly smooth muscles of them clenching and unclenching as the white flesh ridged between his clutching fingers.
Charity groaned beneath her brother's grinding cock, and her breath caught in her throat as he hauled her up tight against his pounding loins, and he felt her draw her thighs even further apart, flexing them back to either flank of his sweating body which caused the moist, clasping opening of her cunt to flower open, receiving his great knobbed cudgel to even greater depths, the blood-engorged head of it flicking past her womb-neck with every plunging stroke.
Now, her head rolled and swiveled on her neck in delighted, highly distilled ecstasy, the last twinges of pain in her vagina gone from her, as her legs, on either side of his thick, impaling cock quivering and jerking, spasmodically, lewdly, splayed open to him, and her tongue, on slippery hinges of its own slithered in and out of his mouth, in duplicate of the pistoning action below, while satiny sounds of love-rapture gurgled in her throat. For the first time in her young life, she experienced… she lived… she loved… she fucked back at him with everything in her, her whole being vibrant and attuned to every nuance… every sensation that was in her. In retrospect, had she been able to think clearly, at that moment, everything, from the licking and sucking of her genitals, the stretching and the entry of his huge penis had prepared her for this total commitment to the joys of copulation. Her brother had done well by her, he had succeeded in arousing the sleeping beauty of sex for her.
Truly, she thought that the warm, hard, live thing inside her, filling her belly, was a key, a key that was opening the lock of her sexuality… opening it forever, as her cunt had been opened by him.
And, as she lay under him, taking his long, hardened member deep up into her, she found that when she tensed her thighs, straining the cords of her neck and back, writhing her genitals up tight to him, relaxing and tensing the muscles of her vaginal vault, there was an intensity, a delicious blissful sensation, she never in her wildest dreams would have believed possible. Suddenly, she wanted to give back as much as she was getting… and, dear God… she wanted it never to end… never!
Don began to pound into her with sledgehammer force, taking longer, as well as faster strokes, drawing his rock-hard cock nearly out of the snug, moist sheath that clasped at it, hungrily, then slammed back into her upraised crotch until his sperm-laden balls slapped hard against the hairless puckered hole of her tiny naked anal passage. God damn! His balls ached! The pressure building in him made his head swim with ever-increasing lust.
Sliding his hand down over the tight skin of her exquisitely formed buttocks, undulant and lascivious under his palm, he searched with a finger for the secret, brown ring of the tiny nether orifice nestled there between the working orbs of her ass-cheeks. He felt her sudden intake of breath and a loud moan of mixed pleasure and shock came, involuntarily, from her mouth as he fingered its soft, warm flexing movements while she thrust up against him, passionately, welding their loins together in the ages-old dance of genital sex. A small rivulet of warm, slippery and viscous fluid seeped down to run from her moist, widespread cunt to moisten her forbidden back passage. Teasingly, his finger lingered there, taunting it, purposely, before attempting any further move.
Don looked down at her and said, gutturally, "I–I'm going to do something now… that'll really make you flip! I'm going to shove my finger up your asshole… as hard as I can!"
And, in spite of her total arousal, Charity was shocked. She struggled with herself; her breath came short and hard for a moment. There was a flashing feeling of instant abhorrence that was replaced with equal speed by a lewdly erotic acceptance of his proposed act, and she was surprised when she heard her own voice saying: "Yes… oh, yes… Don darling! I want it… I want you to… to shove your finger into my asshole!"
Damn! She learns fast! His body-mind screamed with lust as the words spilled from her mouth. God damn! His cock felt expanded and hardened almost to the bursting point! He would explode in jetting streams of cum, it seemed, in just a few moments. He fumbled, momentarily, his long finger searching out the round, tightly puckered hole. He found it and pushed the tip of his finger into it with a quick, almost brutal thrust, feeling the elastic ring of muscle give way until the soft, spongy passage accepted it up to the first knuckle.
"Oooooooooooooooohhhhhhh! My God Don!" Charity gasped painfully. "That… h-hurts!"
Christ! He had never had a fuck like this… never! As his cock fucked in and out of her, mercilessly, he could feel against the bottom of it the bulge of his own finger in her rectal passage, and it added another tremendous surge of sensuous eroticism to his sensate prick driving deep up in her steaming pussy. He squirmed his finger in harder and heard her grunt and cough with the discomfort of it, even as her cunt rode up and down his pulsating member. Then, he began to rotate his finger and pushing inward at the same time, buried it to his palm deep in the rubbery warmth of her rectum, and she moaned, incessantly beneath his rutting body.
Oh, God! God! Never… never before had she experienced such pleasure-pain. The pain was there… in her anal passage, pain caused from his finger as it wormed salaciously around, now, in rhythm with his plunging hardness. Clearly, as in a vision, she realized the duality, for even as the sharp twinges of pain in her rectum gave her tremendous discomfort, yet there was an unbelievable, over-all, sensuously erotic ecstasy, the rapture of it pervading and filling her loins and belly and slashing upward, the sensation was there, also, in her vibrant, swollen breasts.
