She stood with her hands on her hips and looked along the shore. Rocky outcrops, sandy coves, and whitewashed private villas dotted all along the coast and the sparkling crystal sea, stretching out to the horizon. 

“I’ve missed this place so much. Thank God it hasn’t changed a bit.”

Kept away for three whole years by lockdown, it was so good to be back. Now both nineteen, my sister and I were the apples of our parents' eyes.

Ruby looked magnificent as she looked back out to sea. Plump bottom, slim waist and the sweetest little titties topped with big, pink bullet nipples.

She was completely nude; we all were. Everyone was in this naturist paradise on Lanzarote’s rugged north east coast. 

“And as for you, young man, well, I think you’re bigger than your dad.” Mum’s eyes dropped to between my legs, and as the meaning of her words sank in, my cheeks flushed red with colour.

“Haha, she’s right, Ray. You’re really hung,” Ruby giggled, pointing.

Dad leaned over and punched me on the shoulder. “That’s my boy, a chip off the old block, don’t let them embarrass you. Anyway, I reckon I’ve still got an inch on you yet.”

I couldn’t help but look. Dad’s big cock emerged from his thick jungle bush of pubic hair and lolled lazily sideways, the fat head hanging over his hip, pendulous and weighty.

With alarming ferocity, my own dick suddenly started to lengthen and thicken, each beat of my heart pumping more blood into my shaft, which was twitching and bouncing with a life of its own.

We were very open sexually, but I wasn’t quite ready to lie there in the nude with my cock rock-hard in front of all my family.

“Time for a paddle, I need to cool off.” I quickly got up from my lounger and jogged down to the sea, my meat swinging wildly from side to side. Ruby chased after me, took my hand, and we both ran into the surf, screeching with delight at the wonderful freedom of being nude and shameless together. 

We stood for a while in the shallows, relishing the warmth of the sun and the cool Atlantic Ocean. The head of my penis emerged from the water as I rose to my full size and power. Ruby pushed it down, but it sprang back upwards with a splash. 

“My goodness, Ray, you do need to cool off.  It’s so hard. And so hot.”

She encircled the root of me under the water and gave it a squeeze before swimming gracefully out into the calm, clear water, the twin orbs of her buttocks beading with moisture as they broke the glassy surface.  

I looked back at our villa. Dad was kneeling by Mummy’s sunbed. Her legs were wide apart as his hands moved slowly and deliberately up her thighs and then over her big bottom. It was clear he was doing more than just applying sunscreen.

The cool water was having the desired effect, and with my erection starting to subside, I wandered back across the sand just as my parents got up to go indoors. 

Mum’s hips swang from side to side, and so did Daddy’s giant dick, rock hard and almost vertical.

Ok, time for their so-called afternoon nap, I thought.

I dried off with a soft beach towel, flopped down on my sunbed, and grabbed the factor 30. I smoothed the lotion over my taut, lean body, savouring the feeling of my firm, young muscles under my fingers as I covered my six-pack abs before both hands dropped down to rub the cream all over my freshly shaven cock and balls, taking my time to work it slowly all along my length. Feeling myself rising again, I thrilled at being nude and erect in public, uninhibited and brazen, my hands moving up and down along my throbbing pole, lost in my own little world with the distant stirring of orgasmic anticipation building deep within my loins.

“Don’t mind me, just have a wank right here in full view of everyone, why don’t you?”

Ruby had evidently finished her swim and must have sneaked around behind me.

I half turned, startled. 

“I’m not having a…”

“Oh, okay, okay, you’re not having a wank,” she cut me off. “Your penis just happened to become erect as you were rubbing it. With both hands. For five minutes. But you definitely weren’t having a wank, that’s clear.”

I gave a little laugh to let her know she’d made her point. “It’s the sunshine. Sorry, it makes me fucking horny.”

She ruffled my hair. “No need to say sorry, I’m horny too. It's not so obvious for us girls, but,” she lent in close, “my pussy’s fucking molten.”

She came round to face me, her bare mound at eye level.

“Where are Mum and Dad?”

They’ve gone in for their, er, nap.” I gave my sister a knowing glance and she rolled her pretty eyes.

“Oh not again, they’re like two fucking honeymooners, and she’s such a noisy bitch.”

Right on cue, low moaning started up within the villa and soon turned into high-pitched wails accompanied by the rhythmic slap of flesh on flesh in a sordid sexual symphony. 

Ruby stood silently listening for a while. I noticed that her nipples were erect and her pussy lips were glistening, whether from the ocean or arousal, one could only speculate.

Mother’s craven cries seemed to put Ruby in some strange hypnosis, and she slowly wandered in without another word to me.

I watched her go, her huge butt cheeks wiggling in the same way as our mum’s had done, and one hand reached down between her legs. 

Oblivious to passers by, I grabbed my throbbing cock and stroked its full, prodigious length. Thick veins stood out along its shaft, the crown a massive purple bulb. 

Like a moth to the flame, I found myself unable to resist the urge to follow her as if there were some unseen Pied Piper calling us inside with the music of his magic flute.

Inside the villa, the noises were cacophonous. Wild cries of Mummy’s passion and the metronomic slapping sounds echoed around the marble walls.

Ruby loitered by their door which had been left a bit ajar.  She stood stock still, mesmerised by what she saw.

I walked across the cool tiled floor until I was an inch behind her. With my erection pulsing to my heartbeat, I too looked through the open door. 

The sight that greeted me made my cock almost explode with taboo lust. I stepped forward that last inch so that my balls nestled in my sister’s bum crack and my bellend touched her spine. My hands went round to cup her tits then twist those massive nipples, and I whispered something in her ear, a secret long kept hidden, that made her first stiffen, then softly sigh, then reach around to grip my shaft and lead me to her bedroom.

Peter Jenkins had learned to sense when his wife was well and truly fucked.  

After her third or fourth orgasm, her wild shrieks of rapture became mere whimpers of submission, and her writhing limbs went limp beneath his unrelenting onslaught.

Without breaking his rhythm, he told her to expect the end.

“I’m going to cum, my darling, now. I’m going to fill you up.”

Her eyes flicked open for a moment and her hands came round to grip his bum.

Softly she beseeched him: "Yes, my sweet king, please, I beg you, flood me with your potent seed.” 

Summoning all her strength and courage, she wrapped her legs around his waist and pulled him deep inside her red-raw, gaping cunt.

It was almost a conscious act for Peter to release his own orgasm; a cage unlocked, the wild beast within set free, and immediately there was no turning back. He was beyond the point of no return, and the monumental eruption began from somewhere in the core of him, sweet moments of sheer bliss where a higher power took control as the impending detonation built and built. His strokes became the full 10” of his penis crashing into his wife’s stretched pussy with a force that bordered on the violent, and then at last, a period-timeless and immortal—when all that force was focused into a single point of ecstasy deep within his perineum, coiled and primed before a final thrust so violent that her body bounced up off the mattress as the first jet gushed deep into her inner sanctum, followed by a dozen or maybe twenty frantic plunges of his dick into her hole, each instinctively timed so that his sperm pumped at the apex point.

Eventually, the storm abated, and they kissed with love and beauty that could only have been heaven-sent.

In the afterglow, Peter whispered to his wife, "Virginia, my love, Ruby and Ray are so grown up, so sexual, and so perfect for each other. Do you think they…?”

He stopped his question in mid-sentence and cocked his head to better hear a distant noise. He looked down at his wife and, with a knowing smile, she said to him, “Yes, my love, I think they do.”

Ruby’s ankles were crossed and locked behind her brother’s back, and her arms clung round his neck. Her body jerked and jolted as yet another orgasm erupted.

His beautiful buttocks spread wide as he withdrew his length then powerfully flexed as he ploughed his swollen penis once more into her depths.

Some basic instinct told him that she’d reached her limit and it was time for him to seed her. A hidden valve inside his loins flicked from closed to open, and from within the deepest part of him arose a mighty torrent.

“I’m going to flood you now, my love.”

"Yes, Ray, give me every drop of it.”

Her hands reached down to grip his cheeks, nails digging deeply into flesh as she pulled him further in, her legs now spread in an obscene display of total submission as the last few hammer strokes crashed into her young pussy and her brother’s onslaught came to its crescendo.  

Virginia Jenkins squeezed her husband's hand as they both watched from the doorway. Their hearts filled with parental pride, he whispered to her softly, “The apple never falls far from the tree.”
