The two girls sensed Dave's impending release and began grunting desperately, moaning their pleasure into one another's cunt.
And Roxanne, too, picked up the vibrations of her children's frantic pleasure. She felt her pussywalls clutching and releasing Dave's cock as the first convulsions of ecstasy flashed through her big cunt.
"Oh, take it, Mom! Make me shoot it… so… damn… good!" Dave bellowed.
The Fildert boy was the first to come and he blasted a healthy load of jism into his mother's pussy. He spewed out so much cum, in fact, that the sticky white stuff oozed out between her ravaged cunt-flaps, drenching her curly pussy-hair to the roots. The mixture of the teen's jism and her abundant cunt-fluids were soon whipped into a steamy froth as they continued to fuck while Dave emptied his load.
Then both the twins' cunts began clenching and gushing fresh pussy-cream as they found themselves gripped by the throes of a mutual orgasm. Candy tensed her legs around her sister's head, trying to force Sandy's tongue deeper into her sopping cunt as she rode out her gut-wrenching climax.
And as Sandy came, her as hole spasmed around her mother's finger as Roxanne tried to force her digit as far into her daughter's ass-passage as she could, digging her long fingernail into the tender flesh that lined her virgin ass-tunnel.
"Ahhhh, Mom, you're killing my butt… so… good… yeahhhh!" Sandy cried, pulling her head out from between her mother's twitching legs.
With the sight and smell and sound of her three children orgasming all around her – not to mention right in her – Roxanne began submitting to the demands of her climax as it swept through her fiery loins. Her arms and legs stuck out straight as if she'd just been given an electric shock and she shrieked madly, shaking her head from side to side like an incurable epileptic, the powerful seizure of her climax threatening to shake and snap her body like a tattered dishrag.
"Ohhhhh, God, so damn goood! Aieeeeee!" the woman yelled. "Fuck me, fuck me, fuck me!"
The four Fildert's thrashed and bucked, on the floor, spasming irregularly, hopping about on the fuck-juice-soaked carpet in a free-for-all of gripping sex-madness. Their screams and moans became one long wail of grateful, lustful release. They were beyond all thought, now, immersed in that sweet oblivion that is achieved only through an onslaught of overpowering sensation. And they all rode each and every ecstatic wave of all encompassing bliss out to the very end.
But instead of winding down into a quiet, restful hush, they all sat up and stared at one another in wonder, amazed at the power of their quadruple multiple climax. And they all knew that they couldn't stop now, not when there was a chance to repeat the glorious experience they had just been subject to.
The twins sat close together, arms around shoulders, sniffing their cum-drenched fingers to maintain the level of excitement, the aroma of juicy cunt enough to keep them primed for more sex.
Roxanne rolled out from under her gasping son and scooped out a load of fuck-sauce from between her legs. She licked the musty goop from her fingers, smiling at her daughters, her eyelids half-closed and heavy with lust.
Dave raised up on his side and stared at his mother, still trying to catch his breath. But, even tough he looked like he needed to rest before beginning another round of frenetic fucking, his cock began growing again, filling with fresh blood.
"I want it in the ass this time," Roxanne said seductively. Grabbing her son's chin, she said, "Do you think you can handle a little ass-fucking?"
"That's not the question, Mom," Dave replied, his strength returning slowly. "The question is whether you can last long enough to take a full load of my cum in your butt. I say, let's go for it." Sandy and Candy helped, to roll Roxanne over.
Then they grabbed her sweaty hips and raised her ass high in the air. Each girl grabbed one asscheek with both hands and pulled the fleshy buns wide apart, revealing her knotted shitter for the pleasure of her young son.
Candy jammed a finger into her pussy and brought out a thick glob of cunt-slime. She then applied the fragrant goo to her mom's butthole, working the stuff into Roxanne's ass to grease it up for Dave's still-growing prick.
"Okay, brother," Candy said, licking the remaining fuck-slime from her finger. "She's all ready for fucking!"
Sandy slapped her mother's ass like she was urging a horse to giddyap. "Go to it, Dave. I can't wait to see you fuck her."
Roxanne slipped her hands in under her chest and began massaging into her asshole. She was still enjoying the last flashes of her climax as sparks of lust still glimmered in her cunt. But now she wanted that lingering ecstasy to become transferred to her ass, where Dave could again stir her desire back up to a fever pitch.
Dave walked up behind his mother on his knees, dragging himself across the wet carpet until he could touch his cock-tip to his mother's steamy asscrack. He slid the end of his prick up and down in the crevice of her ass, teasing her.
Biting strands of the pile carpet to keep from screaming out her pleasure, Roxanne tried to hunch her back spins Dave's cock. But now all three of her kids were playing the teasing game, and Sandy and Candy struggled to hold Roxanne's ass just out of the range of their brother's big dick.
"Go for it, Mom!" Sandy yelled. "You big slut, I said beg for it."
The three kids laughed, but thou they all sighed delightedly, noticing that their horny mother was getting off being treated like a common whore.
Then Candy brought her hand down crisply against Roxanne's asscheek, raising a bright-red welt. "Take that, you big dripping cunt," the girl yelled. Then she backhanded her mother's ass just as hard.
"Ohhh, stop! Don't hurt me!" Roxanne cried, but she, too, was getting off playing this little game, and her protests were actually just playacting.
Then the twins whaled down on their mother's ass with a flurry of hard spanks, slapping the tender ass-flesh as hard as they could.
And by this time, Dave's cock had grown to full size, and he was jacking it slowly back and forth, licking his lips as he watched his sisters smack the bejeezus out of his mother's clenching asscheeks.
"Okay, girls, move aside," he said. "It's time for the main event."
Dave spit into his hand and then worked his saliva into his hot cock-flesh. His prick-tip was a fiery red and the shiny skin was drawn tight. A drop of viscous pre-cum appeared in his piss-slit, and just before he began to thrust his cock against his mother's ass, Sandy leaned in and quickly swiped the pearly drop of jism off his cock with a swift flick of her tongue.
"For good luck," she said, swallowing and rubbing her belly.
"Gimme some, too," Candy pleaded, and she leaned over to give her sister a deep French-kiss, her tongue exploring Sandy's mouth for the flavor of fresh cum.
Dave was turned on by the sight of his sisters as they fell into one another's arms and began to kiss savagely. But he was even more excited by the sight of his mother's ripe and greasy asshole.
"Okay, Mom, pretend you have to take a shit," Dave commanded.
After a few seconds, Roxanne's asshole snapped open with a sticky sound and Dave felt hot air wafting in and out of his mother's shitter. Arching his hips downward, he took aim and then thrust his cock full-bore straight into the depths of Roxanne's waiting bowels.
"Aaagggghhhhh!" the Fildert woman cried out as the first blast of pain tore through her guts.
The sound of his mother's tortured voice and the feel of her madly clasping ass-tunnel thrilled Dave mightily. It took him only a few moments to bring his fucking motion up to full steam, and then he was plunging into Roxanne's asshole ferociously, his balls slapping into her upturned pussy-flaps with each powerful thrust.
