Jimmy was still confused about why his mom and sis would act like lesbians, but he sure as shit wasn't going to look a gift horse in the mouth. If they wanted to play around together it was fine with him, as long as he got his share.
Confident now, all of his inhibitions long gone and aware that they wanted him every bit as he lusted for them, the boy walked up to the bed and stood beside it, making his cock jump and pulse.
Spread out on her back, Diana grinned and said, "I do believe that your brother needs a fuck, Holly."
Holly, still on her knees, swung her head around to look and blinked when she saw that gigantic prick looming up like some medieval warclub.
"You gonna fuck him, Mom?" she chirped.
Diana hesitated.
She most certainly intended to fuck the boy, in the fullness of time. But she could see by the way his cock was jolting and juicing at the tip that Jimmy was going to get his rocks off as soon as he began to slide his prick in and out of a cunthole.
How frustrating that would be!
So it was not totally without self-interest, nor through selflessness, that she shook her head. Jimmy gasped, about to squawk a protest, thinking that his mother was going back on her word and breaking her promise.
But Diana said, "I think that you should fuck him, first, darling, if you want to."
Holly wanted nothing more, at the moment. The girl thought that their mother was being very generous to give her the first crack at his magnificent prick, not realizing that Diana was acting for her own ultimate benefit, knowing that he would last longer the second time – and, too, that she would be even hotter for it, after she had enjoyed the dark pleasure of watching her teenaged children fucking.
"Yeah – throw the beef to me, brother!" Holly cried, shifting her haunches around toward Jimmy. Her head sank down to the bed and her ass hiked up higher, thighs parted, pussyjuice streaming down her crotch.
"Fuck me like a dog, Jimmy!" she urged. Jimmy glanced at Diana, who gave him a nod of approval and encouragement.
Jeez – we're a funny family, the boy thought quite happily as he knelt down behind his sibling's trim little ass, girding his loins for the game.
Holding his prick by the hilt, he levered it into the right angle and nudged the tip into his sister's cunt from under her quivering ass.
He paused there, savoring the final instants before they well and truly shattered the incest taboo. Diana slid down level with their loins, ready to watch as she waited for her own turn on that sweet cock.
Holly's cunt was sucking on her brother's cockhead, tugging gently, pulling it in. Half of the fat purple slab was embedded in her and the boy hadn't humped or thrust at all. Her greedy pussy was swallowing his cock on its own initiative, like some ravening maw.
Diana leaned in and whipped her tongue around on cockhead and cuntslot in conjunction, just for the horny hell of it – for it was evident that no further lubrication was required at that sodden coupling.
Holly's haunches spiraled.
"C'mon, Jimmy! Stuff me!" she moaned.
"Ummmmm! Shove your huge prick up your sister's tight little cunt, darling!" Diana coaxed, giving advice the way that a parent tends to do.
"Don't nag, Mom!" Jimmy grunted.
And then he grunted again as he shoveled his enormous prick all the way up Holly's cunthole, his cumbags swinging in and slapping her bush.
He held his cock buried to the hilt, grasping Holly by the love handles of her hipbones, his back arching as he ground his cock around inside her.
Holly gurgled gleefully. She groped back between her kneeling thighs and fondled his balls, feeling how solid they were and longing for the moment when he began to empty them into the core of her cunt.
Then Jimmy began to haul his cock out and stuff it back in with long, steady strokes. He twisted her by the hips as he screwed in balls deep. Her cunt squished and his cock hissed. Her cuntlips pulled out, clinging to his prick on the backstroke, then her fuckhole enveloped him like a squeeze box as he fed it all up into her again.
Her ass heaved up and shoved back, matching her brother's vigorous tempo, fucking herself on his prick as he pumped it to her with gusto, filling her fuckhole full.
Jimmy pounded straight in and out and his sister screwed her cunt onto his prick – and when the boy didn't shoot off instantly, Diana began to regret her decision to let him fuck Holly first, envying the girl that big, hammering cuntful of potent prick.
He shoveled in with an upthrust lunge that heaved Holly's ass up, bouncing her on her knees, tits swaying beneath her. Then he jerked his own ass up and drove down into her, his flat belly hitting the round curve of her ass as his cock vanished up her pussy.
Diana slipped around behind the boy and shoved her face in between his thighs, her forehead on his ass. She began to lap at his balls as they swung in and out, then slid up and slurped through the crack of his ass and stabbed her lapper into his shithole.
Jimmy yelped and powered in even harder with the added stimulation of having his mom rimming out his asshole, rattling his sister's pelvis with frantic jolts.
Diana lowered her face to lick his balls some more, but as her tongue flashed over them she could feel that they were over inflated and ready to blow off.
Eager to watch him squirt into his sister, she shifted up beside their hips again, just as Jimmy started in on the crescendo strokes.
His cumbags surged and he began to hose her fuckhole plentifully.
As his fat prick stuffed in, he was forcing cunt cum and jizz out of her slot, giving their fascinated mother a chance to see what was pouring into her daughter's pussy from out of her son's cock.
Diana was dizzy with desire as she breathed in the heady fumes of melting cunt and creaming cock and the aroma of girl and boy cum combined.
It didn't last very long. Jimmy was so worked up from watching that although, he was pumping plenty of jism into Holly, it was all cumming out at once, ropes of juice and coils of cream spurting from his pisshole in a steady stream, as he sank in and as he pulled out.
He yanked her back by the hips, hauling her onto his cock, then held her ass steady as he dragged his prick back, gasping and groaning as his balls drained off.
Now, once again, his mother was happy that she had bided her time and still had the pleasure of a fuck – and a longer one – still ahead of her.
Jimmy wound down slowly and stopped humping.
Holly kept on shoving her cunt up and down on his cock for a while as she worked off the dregs of her own cumming. Then she dropped forward, belly down, and his slippery prick came pulling from her pussy.
It stuck straight out, then jolted on up and stood angled before his belly again, running with cream, like some gooey drink on a stick.
Holly's cunt was still wide open, flooding over with cum as thick as condensed milk.
Although she was really keen to get her cunt stuffed now, Diana just couldn't pass up that taste treat. As Holly lay face down, her mother swooped on her pussy from behind, cupping her mouth to the sodden slot and beginning to voraciously suck all the juice from her cunt.
Diana loved her daughter's cunt cum and cherished her son's spunk – and swallowing both of those nectars, blended into one creamy confection, was heavenly.
She gulped away in Holly's cunt until she had it all, then twisted around toward Jimmy. He was still kneeling, his cock jerking around before his loins, his balls filling up again, drop by precious drop.
Diana dropped her head down and took his rampant cock into her mouth. She nursed on the knob, then pushed on down, deep-throating him to the balls. She held his prick buried in her gullet, gulping and gagging, then pulled her mouth back up, inch by slow inch, sucking every blessed bit of the mingled cum juices from his cock.
When she pulled away, his prick was still glistening, but with saliva now, not a drop of cum lingering in the wake of her wanton mouth.
She swallowed slowly, ingesting the last mouthful mixed with saliva. Then she gently pushed Jimmy down onto the bed, face up, his cock towering tall.
It was time for the next step in the double seduction of her kids – time to break the ultimate taboo and make her son a motherfucker.
She threw a leg across, straddling him as she had before – but ready for more than just the tip of his cock now, wanting every inch followed by every foaming drop.
Holly twisted around to watch.
How happy they all were that Daddy had gone hunting.
