Callum finished his morning shower, turned off the jets and stepped out, reaching for a towel. He dried himself down and then turned to admire himself in the long wall mirror fixed to the bathroom wall. As always, he was pleased with what he saw. His naked body was lithe and supple as a twenty year old's should be and he was proud of his cock that was standing to attention as it always did in the mornings, Callum having forgotten the last time he had woken up without a raging hard-on.
Callum gave his cock a little tug as he turned back from the mirror and went back to his bedroom. The window was wide open on account of the hot summer they were enjoying and through it he could hear the muffled voices of his father Jim and his grandfather Clem coming up from the garden.
Callum hurried over to the window and peered out. His father Jim and Jim's father Clem were lying side by side, their sun lounges pushed up close to each other, and like Callum they were both naked.
"Hi dad, hi pops," Callum called down to them, "where's mum and gran?"
"Gone into town," said Jim.
Callum licked his lips at the bewitching sight of Jim and Clem stroking their hard-ons.
"You two are up early this morning," Callum said, giggling.
"Why don't you get that tight butt of yours down those stairs," said Clem, looking up to the window and smiling at the sight of his naked grandson with his cock in his hand, "and join us? Your dad and I are feeling really horny."
Callum hurried down the stairs, pleased that his father and grandfather had waited for him to join them before gettung down to business. The absent ladies, Callum knew, wouldn't mind in the least and would, of course, join in the fun as soon as they got back from the weekly round of Saturday morning shopping.
As Callum emerged onto the patio, his hard cock leading the way, Jim and Clem turned their heads and smiled at the young man enjoying his nudity and who had certainly inherited the family's love of hot taboo sex.
"Bloody hell, son," said Jim, "that hard-on of yours is magnificent, ain't it, dad?"
"You never spoke a truer word, son," said Clem, licking his lips as Callum came up to his father and grandfather and stood in front of them, proudly displaying his cock and balls to his relatives without an iota of shame nor embarrassment.
"Thanks dad, thanks pops," said Callum, "but it ain't as if you're seeing it for the first time. It's still the same cock it was when we sucked and fucked with mum and gran last night."
"We're paying you a compliment, son," said Jim, "so take it in the spirit it is meant."
"I take everything in the spirit it is meant," laughed Callum, never happier than when he and his folks were about to embark on another of their daily sessions of hot taboo sex.
Clem shifted his now old but still athletic-looking body from the sun lounge to get a closer look as Jim opened his mouth and took Callum inside. Clem's mouth watered and he let out a low whistle mixed with pride and admiration as he watched his son sucking his grandson while Callum rocked back and forth on his legs, pumping his fat rod in and out of his father's mouth. Callum's balls, freshly-showered and bright and pink, were slamming rather than slapping against the underside of Jim's chin, Jim making little gagging noises as he sucked his son like a thing possessed.
"Yeah," breathed Clem, like the rest of his family a sex addict of the highest order whose life was ruled by the pleasures of the flesh, "that looks fucking fabulous. Suck your boy's cock hard, son."
Clem held his hard cock in his hand and leaned in to kiss Callum on the lips. Callum eagerly returned his grandfather's snog and, without breaking the blowjob, Jim raised his eyes and smiled, delighted to see his father and his son locked in a passionate embrace.
"Fuck," Jim thought to himself, "pity mum and Jean are missing this," he went on musing as images of his mother Lena and wife Jean, Callum's mother, came into his mind's eye.
"Well, this looks like a lot of fun," came a male voice from the garden gate and breaking into Jim's reverie.
"Sure fucking does," a female voice rejoined.
Clem turned his head and smiled at the sight of his eldest son Jed rubbing his hard-on through his shorts and Jed's daughter Livvie who had blossomed into a beautiful young lady, having turned eighteen a few months earlier and thus now eligible to participate in the family gangbangs. Livvie was attired, also in a pair of shorts but unlike her father who was wearing a singlet that enhanced his chest and shoulders, Livvie was wearing a top so tight, her firm breasts looked like they would burst through at any moment.
"Hi, you two's," said Clem, "what brings you here on a fine Saturday morning?"
"Can't you guess, grandpa?" giggled Livvie. "Now that I'm a fully paid-up member of the club, I want to join in as much as possible."
"Hi uncle Jed, hi cuz," Callum said, using the pet name he always did for his cousin, "dad's giving me a great blowjob."
"So we can see," said Jed, looking forward to getting his own cock sucked before much more of the morning had passed.
"Where's that wife of yours?" said Clem to Jed, as Clem's eldest son reached inside his shorts and pulled out his aroused prick and started masturbating. Jed's eyes were stuck like glue to the spectacle of his brother sucking his nephew while Livvie, also watching the intense scene through her beautiful emerald eyes, slipped a hand down her tight shorts and started to finger her pussy.
"Gone to the shops," said Jed, "but she says she'll come along later. Don't tell me mum and my sister-in-law have gone to the same place?"
"Of course they have, son," said Clem, torn between watching Jed wanking and Jim sucking Callum. The patriarch's eyes darted back and forth, eager not to miss a thing. "I'd have thought Livvie would have gone with Erin, too."
"Not me, grandpa," said Livvie. "I just want to get on with some action."
"She's taken to it like a duck to water," said Jed proudly, a bemused grin on his face.
Livvie licked her lips at the sight of her father pumping his hard cock in his hand and which, only a few hours earlier the previous night, he had fucked his daughter with during another of the threesomes she and her parents had recently started out on, now that Livvie was a consenting adult.
"Get 'em off, then," said Jim, finally releasing Callum's cock back into the atmosphere and standing up alongside his father as did Callum and the three men began masturbating together. Jed was out of his clothes in a flash and moved over to join his father, brother and nephew and Livvie gasped at the sight of her horny male relatives with their hard pricks on display and their tongues hanging out as they waited with eager anticipation for Livvie to disrobe.
Livvie quickly removed her clothes and turned to stand naked in front of the men. Clem, Jed, Jim and Callum gawped at Livvie parading her nakedness in front of them, caressing her tits in her hands.
"Oh boy, sweetie," said Jed, as proud as any father could possibly be as his eyes swept over his daughter and her full frontal nudity before coming to rest on the neat triangle of her very full bush, "you look incredible."
"Thank you, daddy," Livvie replied, "and by the look of all those nice suckable rods, I think its about time I gave them some attention."
"Me first," said Jed, "I am your father."
"As if I didn't know," grinned Livvie as she dropped to her knees and the men clustered in a semi-circle around her, surrounding her with four rock hard pricks and four sets of sweaty cum-filled balls. Livvie licked her lips as she surveyed the men standing erect and proud in front of her, shivering with excitement and feeling herself start to come out in goose bumps.
Clem took hold of Jed's cock in his hand and pointed his son towards his grand-daughter.
"Suck it hard, lass," said the old man, "let's see how well you've progressed since you became a member of our club."
"Oh, she's progressed all right, dad," laughed Jed and was about to say something else but his words were cut off as his daughter reached out and cupped a hand around his balls, twerling them around and examing the head of her father's cock which was fully exposed through Jed's retracted foreskin. Jim and Callum were wanking like mad as they watched with growing impatience for the fun to begin.
"You've all got such beautiful cocks," said Livvie, "I'm so lucky to have been born into such a horny family."
"They're all for you, lass," said Clem, reaching out a hand to stroke Jed's arse as Livvie moved in closer, breathing in the manly scent emanating from Jed's knobhead. "Suck your daddy hard."
Livvie opened her mouth and, smiling up at Jed, took him into her mouth. Clem removed his hand from where he had been happily touching up his eldest son's bum and resumed masturbating alongside his youngest son and grandson. As the head of Jed's cock hit the back of Livvie's throat, Jed threw back his head in ecstasy, delighted in the knowledge that all the patient hours his wife, Livvie's mother Erin, had devoted to educating their daughter in the art of cock-sucking had paid off handsomely.
"Oh yeeeesss, sweetie!" Jed cried as his daughter clamped his cock in her hot wet mouth, "this is the best blowjob you've given me yet."
