Nearing the archway, Bunny and her father glanced at each other as they heard the sounds of frantic coupling coming from the front room.
They moved on and looked in.
"Gee whiz!" Bunny gulped.
"Holy shit!" Peter muttered. Marianna was down on the floor on all fours and Jack was throwing a doggy fuck into her from behind. Bunny and Peter gaped at the lascivious scene. Totally engrossed in fucking, neither mother nor son noticed, at first, that they had come under observation.
Jack jerked in, his ass corkscrewing. He was heaving his mother's haunches up as he buried his cock in her fuck-box. She groveled like a bitch in heat, her ass shifting from side to side. If she had had a tail, she would have been wagging it.
Jack held her by the handles of her hipbones, hauling her back as he plunged up her pussy. His cumbags swung in and slapped against her crotch as his lean belly jammed to the curve of her ass.
Her head was lowered to the floor, her ass heaved up to the highest point of her posture, her heavy tits brushing on the carpet. Her eyes were flickering, glazed by lust and her mouth was open, lips slack.
Those lips were all smeared with spunk and the onlookers knew that she had sucked her son off before she started to fuck with him.
Bunny and Peter exchanged a glance.
But how could either of them cast any blame?
Smiling, they turned to watch again.
Jack, kneeling upright, saw them first.
"Oh oh!" he gasped, missing a beat.
Marianna raised her head and blinked.
She looked just a bit sheepish.
But the horny woman was filled with lust and full of her son's prick and her embarrassment was nothing compared to her desire.
"Don't fucking stop – don't stop fucking!" she wailed, jerking her ass back against his loins.
Jack had lost the rhythm in his shock and surprise at being caught fucking his mother. But now he realized that his father and his sister were both naked and grinning encouragingly and he saw that there was nothing to worry about.
He began to pound up her pussy again.
His violent hinges were driving Marianna forward. Locked together, they crawled closer to Peter and Bunny. The thrilling sight of a mother-fucking session was turning the father and daughter on so much that, for the moment, they forgot about their own loins, concentrating on the sensation of watching Jack throw his cock steadily up into his mother's forbidden fuck-hole.
Peter had his hand on Bunny's trim ass and he clipped his fingers into her gooey groin from behind, playing with her pussy. She was holding on to the huge lever of his cock, stroking it slowly up and down. But that mutual caress was only incidental, at the moment.
"Oooooh – yeah, yeah," Bunny whimpered.
"Fuck Mommy, Jack – fuck her like a dog!" Jack jolted in vigorously, his backbone twisting as he buried his cock.
Marianna wound her limber pelvis around, screwing her cunt-sleeve up and down on his driving stalk.
"Cum, darling – spunk Mommy's fuckhole!" Marianna gasped, as she began to dissolve on her son's cock.
The depraved woman had been really and truly enjoying a cuntful of hard young prick to begin with, but now that her husband and daughter were witnessing the act she loved it even more, basking under their fevered gaze in ecstatic exhibitionism.
She gave Bunny and Peter a lustful look as she slammed her ass back on Jack's loins.
"Here it cums, Mom!" the boy rasped.
His fiery fluids hissed up his cock-shaft and squirted into his mother's cunt in a deluge. Marianna wailed as she felt her son's slime steam into her cunt. She melted again, her fuckbox turning to jelly on his jizz load.
Jack hauled her about by the hips, twisting and turning her haunches as his cock darted in with lightning strokes, draining off spasmodically.
Emptied, he clung over her for a moment, panting like an animal. Then he drew back. His prick came out of her soaking pussy with a slurp and the youth toppled over, spread-eagled on the floor.
His cock swayed over him like a reed in a storm.
Bunny's eyes were glued to her brother's cock. That glistening stalk looked so fucking flavorsome that she thought her tongue was going to ignite.
She knew how delicious Jack's cock-meat and cum were, but now that it had been basted in her mother's cunt-hole it looked even more scrumptious.
The whole huge cock was drenched with cunt cum and that creamy nectar was streaked through with thick ribbons of jizz – a filigree of fuck-juice.
Bunny gave her daddy a meaningful glance, raising her eyebrows for his permission. She didn't want him to get jealous. But jealousy had no place in this situation.
He gave her a smile of approval.
Bunny stepped over and knelt down beside her prostrate sibling. She bent down and rubbed her nose against the head of his cock, sniffing and snuffling. The fragrance of a pussy-soaked cock tantalized the girl.
She sucked it into her mouth.
Peter knelt down beside his wife and they shared a look of complicity and conspiracy. Equally guilty of incest, there was no blame and no shame.
Together, they watched their daughter sucking her brother's slimy prick with relish.
Bunny tongued up and down his stalk, then swallowed it, nursing all the fuck-juice and cunt cum from his cock. When she rose up, his cock was polished to a sheen by her saliva.
She turned and looked at her mom and dad, grinning and parting her lips so that they could see the film of fuck-juice on her tongue.
Marianna leaned back on her elbows and silted her groin up, her ass rising from the floor. She knew damned well what her naughty daughter wanted next. The family had already enjoyed almost every possible form of incest – but one.
Lesbian love was still ahead of them.
Bunny crawled over and knelt between her mother's widespread thighs. Her head inclined. Marianna's cunt was tilted up under her chin like a creamy delicacy served on a hairy platter and Bunny gazed at it in hungry anticipation.
Peter gasped when he realized what a treat he had in store for him and Jack leaned up, fascinated. Bunny was licking her lips as she leaned over her mom's cunt. She already knew how yummy that mother's milk was, having just tasted it on her brother's drenched cock – and she knew for sure that cunt-juice would be even more delicious when she sucked it straight out of her mother's melting pussy.
She leaned down and licked up the inside of Marianna's thigh, one side and then the other. Marianna whimpered and jerked her swampy cunt up eagerly. Both mother and daughter had often fantasized about such a situation and now the magic moment was at hand.
Bunny lingered over the approach, teasing her tongue and teasing her mom's cunt by the delay.
Then she flicked her tongue against Marianna's clit.
Marianna jerked as if she had been shot through by a high-voltage current. Bunny drew back for a moment, savoring that first taste on her tongue.
"Ooooh," she squealed, inhaling the musky fragrance that was steaming from her mom's cunt, tantalizing her tastebuds and whetting her appetite.
She dove enthusiastically on that perfumed pussy.
Bunny had never sucked a cunt before, but she had thought a lot about just how she was going to do it when she got the chance – and she knew with the very first slurp that it was the sort of thing that comes natural to a girl, instinctively, needing no practice or training or previous experience at the tasty cunt-table.
Her tongue stirred and whisked and churned in Marianna's juicy slot, then stabbed up her cunt-sleeve, tongue-fucking in and out steadily. Marianna thrashed about in bliss as her daughter gobbled her cunt. Her fuck-box was flooded with her son's spunk, not to mention her husband's jizz, and Bunny was sucking out that fuck-juice blended with cunt-cream and swallowing it down in a frenzied rapture.
She was using only her tongue to begin with, but now the cunt-hungry teenager clamped her mouth on her mom's cunt. Her lips plastered to the slot like a suction cup on a clogged drain. She inhaled and her mouth filled.
Bunny's hands cupped her mother under the cheeks of her ass, lifting her loins up as if her cunt were a goblet she was draining to the dregs.
Marianna tightened her thighs around her daughter's head, holding her in a velvet vise. Then her legs opened wide again, her feet kicking in the air. There was no need to hold Bunny in her groin. The teenager's lips were glued to her cunt by a paste of pussy-nectar and saliva. She had already sucked all the jizz out of her mom's cunt and now Bunny was gulping down pure cunt-cream – and adoring it.
Marianna wailed as she melted and her cunt cum poured into Bunny's mouth in a foaming flood.
Bunny kept on sucking until she was certain that she had worked off every spasm and swallowed every drop. Then she drew away and turned. There was no need to speak, no need for so much as a speculative look.
They both knew what came next.
Marianna pounced on Bunny's pussy, her lips clamped to it like a limpet to a mossy rock. Bunny jerked her groin up and down in her mother's eager face, juicing off on that slurping tongue and into those avid lips.
Marianna used her tongue like a pliable pink ladle, spooning out her daughter's cum-juice. Bunny sank back, gasping. Her mom lay between her thighs, tonguing up the last succulent drops as they slimed from the teenager's cunt.
Presently, she raised her head, smiling with dripping lips.
Peter and Jack both grinned at her approvingly.
Every last taboo had been broken up.
And there was nothing more to do on this memorable Sunday morning – but do it all again…
