Incest! her conscience railed. This is incest!
No, no, no! Marge moaned inwardly. It's his arm not his penis! And I've got to have it! As much of it as he can stuff up me! Even if it kills me to take it!
"More, more, more!" she bleated, nearly passing out with the rapture it produced when his fist started bumping against the hypersensitive neck of her uterus, jolting that feminine organ higher up into her body.
"But, Mama, it's in up to my elbow already!" Kenny squeaked. "Are you sure?"
"Yes, Yesss… Aaaggghhh… I'm sure! Impale me with it!Give it to me… ooouuuu… clear up to your… aaahh… shoulderrr!!"
What the passion-crazed woman told her son to do was a physical impossibility, of course, but the excited child did his damndest to please her, and her ravenous snatch actually did swallow his elbow and a couple of inches of his slender upper arm before his fist had her womb shoved up into her shivering torso far as it could go without rupturing something inside her.
"Gawd, gawd, gawd!" Marge chanted, her head burrowing into the pillow as she clawed the mattress beside her quaking hips. "I want… oooohhhhhh… I wa-want…"
"Me to fuck you with my arm?" Kenny asked eagerly.
"YES, YES!" she panted, revolving her hips in a tight, circular motion. "Oh, Good Lord… yesss do it… doo itt!!"
Kenny grinned confidently. He was pretty sure she would let him put his aching peter in her hole before long now. But he wasn't in any hurry. He was fascinated with her hairy hole. It felt nice to have his arm inside it, where she was real hot and wet and soft as velvet. Keeping his fist clenched, he started pulling his arm out to the wrist and sinking it back in till her pulsating orifice snapped over his elbow. In and out, in and out he fucked her with his arm, and the way she sobbed and shook made his own insides feel like they were melting and running together.
"Uunnn-aaahhhhhhh…uunnn – ooohhhhhhh!" Marge moaned as the lewd pleasure of her son's rhythmically pumping arm washed over her in a continual stream of flood-like waves.
It was obscene to the nth degree what they were doing, but glorious! Marge couldn't lie still. It was too fantastically good, the way Kenny's small fist kept her pleasured womb bobbing up and down in her belly like a cork on a wind-swept lake. She thrashed about rapturously with her arms outflung and her palms slapping the bed.
"Kenny… Ken-nieee!!" she said, the cords connecting her thighs to her groin standing out taut as bowstrings, jerking and twitching as she rotated her hips in a grinding up and down motion which threw her twat up to help her young child stuff his arm deep into her heaving belly. "Christ, yesss! aaahhhhh… give it to me, precious! Lord, but that… feels soo… gooooddd!!"
Sweat rolled off her feverish body. Her breath came in great gasping huffs. A continuous flow of pleasured outcries issued from the tremulous lips of her gaping mouth. The blood-engorged lips of her furry gash clung to Kenny's arm, making liquid, lurid slurping noises when he drew it partway out of her, then fluttered submissively and folded in around his forearm when he plunged it back into the moist heat of her secreting vagina, the deeper end of which responded with a joyously lascivious squishing sound.
Slurp, squish! Slurp, squish! Slurp, squish!
The wet sounds of her steaming fuckhole greedily gobbling then releasing the plunging forearm of her nine-year-old child only added to Marge's erotic pleasure. She had no excuse to fall back on this time. She was drunk, yes, but on lust not liquor. The flames of her perverted passion licked searingly at her insides. If this was incest, then so be it, for Marge was enjoying it tremendously.
With every raw-ended nerve in her keyed-up body she could feel her son's fist bumping her cervix like the head of a gigantic cock. His shaftlike forearm kept the soft, slippery ring of her dilated, hair-surrounded slot pumping in and out as it shuttled back and forth, back and forth, driving his fist like a piston into the very depths of her pleasured abdomen. She hoped it would go on forever, but the fantastic sensations it produced soon became too much for her human flesh to endure.
As the bittersweet tensions of preorgasmic delirium tightened her blood-congested loins, damming up the flow of pleasure until it became the sweetest form of torture on earth, Marge sucked in her breath raggedly and bore down with her heels and shoulders. Her spine bent into a bow-shape. For a moment her arched, trembling body hung suspended in the air, her firm/soft asscheeks quivering visibly.
Then the dam broke and her pent-up sexual tensions flooded out from her groin in concentric waves of boiling bliss. Her climax was unbelievably intense. She grabbed Kenny's arm, already into her up to his elbow, and tried ruttishly albeit unsuccessfully to stuff it up into her stomach clear to his shoulder.
"Nnaaaaa-gggaaahhhhh!!" she cried and fell back weakly, her entire torso shuddering ecstatically. "Cumming…cumming… ooohhh, Good Lord… am I ever… cccuuummmiiinnnggggg!!"
She threw back her head, her eyes rolling up until only their whites could be seen.
"Aaaaarrrrrggggghhhhhh!!"
Sweat rolled off her in sheets as a series of flesh-quaking tremors wracked her febrile form.
"Oooohhhh… oooohhhh… ooooooohhhhhhhhh!!"
Her long, shapely legs flailed about helplessly, the pink heels of her dainty feet beating the mattress erratically.
"Uuunnn, uuunnn… aaaahhhh ooouuuuuuuuuuu!!"
It felt as if the incredible blasts of agony/ecstasy exploding deep inside her were ripping her apart at the seams.
"Uuuuunnnnn… aaaaahhhhh… ooooooohhhhhhhh!!"
The total rapture of it overwhelmed her. All she could do was lie there sobbing brokenly when her orgasm reached its excruciating peak, the satiny walls of her juiced-up vagina grabbing convulsively at her son's pussy-engulfed arm as her perspiration-drenched body shivered and shook in a frenzied dance of mind-numbing sexual fulfillment.
"Can I fuck you now, Mama?" Kenny asked, as his mother lazed in the dreamy afterglow of her all-over cum, whimpering and sighing repeatedly.
"I su-suppose… I might as well… let you," she panted, knowing that after what they'd already done, he would keep at her until she gave in or spanked him, and spanking him was the farthest thing from her mind. "I shouldn't… but all right."
"Oh, boy! Take off your panties, Mama, and your nightie, too!"
He backed his arm out of her with a sluu-uurrppp! and Marge sat up and pulled her nightgown off over her bead, then lay back down and raised her midsection so her little boy could take her panties off her. She could see his face by the dim illumination from the night light in the kitchenette. He was terribly excited. She couldn't help thinking how cute he was as he stripped off his pajamas. His little dick was hard as a bone, angling up from his totally hairless groin.
Neither of them spoke now. A sensual smile of calm acceptance played over Marge's face as she scooted to the center of the bed and spread her legs for him. Perhaps she would hate herself for this tomorrow, but not tonight. The mood she was in, it seemed like this was destined to be. She took Kenny in her arms and kissed him the way no mother should kiss her own son, shivering with erotic pleasure as she insinuated her tonguetip between his inexperienced lips and gradually eased her taste organ into the warm, wet cavern of his hot little mouth.
No verbal communication was required to get the idea across to the bright lad. Tentatively he began licking back at his mother's wiggly, lapping tongue while she held him by his aching stem, her other hand stroking his buttocks. She kept making funny little noises in her throat as she squirmed beneath him, rubbing the sensitive head of his erection in a tiny circular motion within the top part of her wet, feverish crack. He answered one of her muffled sighs with a whimper of his own and instinctively started sucking her sweet-tasting tantalizing tongue.
