She made one last effort to forestall what she knew now had to happen; indeed, it must happen or she would go insane.
"P-Please… Don… w-we can't! We m-mustn't…!"
Her brother moved his head back, momentarily, and said, thickly, "It's too late… Char! We're both beyond the point of no return! Hell couldn't stop it, now!"
Her rational mind — at least, a portion of it that still functioned — recognized a certain truth in what he said, and she knew that the juggernaut of sexual desire that they had released was plunging forward and downward with inexorable speed and force, carrying them with it in its mad, wild, careening course. They could do nothing to stop it! They were trapped in a sensate tangle of illicit, salacious sexuality. Dear God!
Quiveringly, her hands that had gripped his shoulders moved up to cradle either side of his head, pressing his face in close to her trembling loins, unconsciously, giving him her tacit permission to continue; indeed, her hands pressuring against the back of his head urged him on to even greater effort, as his tongue plunged wildly in and out of her sensate cuntal furrow, sliding easily along the short length of her female bud, the seat of womanly sex.
… And, again, unconsciously and instinctively, she relaxed the tension in her leg muscles, allowing her thighs to spread submissively apart as she moved her feet to a wider stance on the rug and her pelvis tipped up with the flexing of her hips to begin a tiny countering back and forth motion to the in-and-out movement of her brother's hungrily licking tongue.
She moaned, softly, the building ecstasy almost too much to bear, but there was another flash of lingering abhorrence that swept through her, a momentary emergency of conscience that tried to tell her: stop! Stop before it's too late! But even as the swift signal reached her mind, there was the jamming counter-signal of the prurient, salacious desires that agitated her loins, demanding, commanding her immediate compliance. The moment was lost! Nothing remained but the potential rapture of wanton joy in their illicit sex act. It was too late! Forgive me! Dear God forgive me!
Her brother stood to his feet, then, sliding his arms up around her, carrying the hem of her nightgown up and over the full round firmness of her breasts, and, automatically, she lifted her arms over her head, reluctantly allowing him to remove the thin garment from her vibrant, young body. He tossed the gown to the top of his dresser, carelessly, and swept her into his sinewy arms.
Charity felt herself crushed against his hard, youthful body, her naked breasts mashed flat, painfully, between them, while below, the hardness of his fully erect, throbbing penis pressed into her abdomen, the heat of it being transmitted to the sensitive skin of her belly. She found herself, then, reciprocating, as in spite of lingering fear, her arms went around him, her hands moving in caresses of affection and love up and down his back, her face tilting up voluntarily for his kiss.
His lips sought hers, found them and welded themselves to her half-opened mouth, his tongue snaking out to burst voraciously between her lips. Her taste buds, sensate and sharpened by the marijuana, detected the flavor of her own vaginal secretions on his tongue, and she wondered at its zest, savoring it. A sudden half-thought overtook her. What does his taste like? Somehow, she found the thought erotic, in the extreme. She wanted to taste it, now! Under the present aegis, she was propelled toward the desire; however, she would have been hard pressed to explain it, for just a few moments previous she would have cringed away from the idea, just as she had been outraged to witness her mother's participation in a lewd oral sex act. A change had taken place in her. Now, she looked forward to it. She wanted to take her brother's excited young cock in her mouth to suck… to love… to give him what she knew now must be a wonderfully satisfying sexual sensation. She guessed it, fathomed it, by her new-found knowledge of herself, as Don's tongue had licked her between the thighs to wild, wanton desire.
Suddenly, she felt as though her legs would no longer support her; they quivered, and she felt them giving way under her. A hand went out to the edge of the bed to keep herself from falling as a wave of dizziness overcame her.
Don, aware that she needed to be lying down, supported and helped her onto the bed, then, began, hastily to strip his own clothing from his eager, anticipating body. As he stood tail above her, he devoured the perfection of her lush, young nakedness, his eyes roving over her taking in every detail of the voluptuous beauty of her. Christ! She's the most!
"God damn it, Sis… You've really got it!" he said.
Charity writhed on the bed in an agony of need, watching as her brother stripped naked before her, standing finally, lithe, lean and muscular, his hard, fleshy penis standing out in virile erection at an acute angle, aiming itself at his navel, while below his testicles, she noticed had been drawn up taut within his scrotum. Oh, his penis is so huge! I–It'll never be able to fit inside me! There's never been anything bigger than my finger in there!
Remembering her virgin state, a feeling of fear arced in her chest, causing her heart to pound, momentarily. Oh, God! I–It'll tear me… hurt me… terribly!
He noted the intent direction of her gaze and grinned at her. "Bet you're worried… Aren't you…?" he asked.
"W-Worried… about what, Donnie?"
"I saw you eyeing my cock, and I got the idea you were worried about whether I'd be able to get it in."
In spite of her trembling body, she had to smile at him; she was not sure whether it was a case of mind-reading or a case of inflated ego. Lightly, she returned, "There is a difference in size, that is…"
"Don't worry, Char… I'll stretch you a little with my finger first… then, I'll fuck you!"
Charity loved her brother, more than ever, from that instant; his seeming concern for her, in the face of his own great need, overwhelmed her. Thank God! He was not going to ram his big thing in her right away; instead, he was going to be slow and gentle, just as he had said he would be.
"Oh, Don… oh, my Donnie…" she murmured.
Then, he was beside her on the bed, his lips on hers, their tongues intertwining, probing each other, as his free hand caressed her breasts, belly, thighs and pubic mound; finally, his hand went down between her legs and covered the whole of her genitals, massaging in a general way the whole oval of her pubic triangle. Her pelvis moved in tiny, churning circles under his hand, and he knew that she was fully aroused… would remain so until she exploded in orgasm. Christ! He was so hot, himself! He wasn't sure that he could hold off much longer. He had to get his cock in her little cunt and fuck her! His balls ached from his great need, and his prick throbbed, painfully.
Shifting his position, he moved to kneel between her legs, levering them apart as he crawled part way into the open vee they made, then lifting by the knees, he flexed them and splayed her thighs wide apart to expose her young virginal cunt completely to him. His eyes gazed hungrily down at her nakedness, the coralline flesh of her vaginal split glistening moistly in the dim light of the room, and peeping out between the fleshy lips of her vulva he could see the deeper coral of the inner petals clasped tightly between the fleshy folds of her virginal pussy.
