"Mmmmmm," purred Rose.
Kent, still holding onto Renee's waist, slid his hands up her sides, past her tits, cradling her underarms in his paws. He lifted her, until her ass cleared his rising joint, then pulled her back, lowering her onto his now stiff spike. When her cunt touched his balls, Renee bent forward at the waist. Reaching around her uncle's broad back, she grasped his erect cock with her left hand and found Rose's gaping twat with her right. Rose scooted herself forward to meet her sister's fingers, but, instead, Renee stabbed her cunt with Arthur's prong. Renee then moved her right hand further, seizing Rose's buttocks, drawing her tight to the stake.
Water sloshed over the Jacuzzi's rim as Kent and Arthur humped the twins. The turbulent jets swirled eddies of synergistic excitement around the conjoined cocks and cunts. The girls cried, whimpered, clawed and bit the men relentlessly pounding their stuffed pussies. Almost simultaneously, Arthur and Kent gave final deep thrusts, fiercely held the writhing twins and let loose tsunami shocks of semen within their convulsed canals.
Exhilarated, but enervated, too, the group staggered from the Jacuzzi. They had just enough stamina left to towel off and finish the food and wine before retiring to the king bed. The satisfied girls curled inward, facing each other, and fell asleep with the brothers spooned against them.
Ever an early riser, Kent woke with his dick squeezed between Rose's thighs at the base of her butt. He carefully dislodged his left arm, trapped under her tits and between her ribs and her left arm. His luminous watch dial indicated 3 a.m. He smiled to himself, knowing his daughters could sleep even through small earthquakes. His hard cock twitched at the possibilities.
Arthur, unlike his nieces, was a light sleeper and Kent's movement brought him awake. He raised his head from the pillow, peered over Renee's naked right shoulder and saw his son lift a finger. "Ssshh! Don't wake them, Dad!" Kent hissed softly.
Arthur instantly sized up the situation and felt his dick thicken where it lay vertically aligned against Renee's ass crack. The twins slept interlaced, almost as a single unit. Golden wisps of Renee's hair fell across both girls' faces and waved gently as Rose exhaled. Their arms lay loose about each other's shoulders, but, their breasts were compressed and Rose's right nipple was embedded in Renee's left areole. The twins' hips and bottoms, however, were naturally separated as their bent knees met and meshed, each creating a gap in their thighs running up to the creases of their cunts.
Arthur and Kent carefully pulled their own hips back from the girls' bottoms and inched themselves downward. Each man used a free hand to bring his throbbing cock to the backdoor of the closest twin. With their knobs softly pressed against the sisters' rosebuds, Kent and Arthur fingered their slits. Moving lightly enough not to wake them, and heavily enough to arouse their pussies' juice factories, the men easily slid in and out. Soon, Renee and Rose were slippery and, even in their sleep, pushed their bottoms back against the intruding fingers.
Kent and Arthur replaced their fingers with their mushrooms and stuck their lubricated digits into the outer recesses of the girls' virgin sphincters. Still moving their dicks in and out of the cunts, but only an inch or so and not fast, the brothers kept widening and deepening their anal penetration by first, one, and then, two, and, at last, three fingers. When each twin was holding three fingers two knuckles deep in her ass, father and son slowly pushed their tumescent cocks fully into the tight, slick, teen pussies. There they rested, allowing Rose and Renee to naturally anoint the shafts with automatic responsive contractions.
Still cautious, Kent and Arthur pulled out of the dripping cunts without alarming the slumbering twins. Resetting their ramrods at the open glistening assholes, they steadily pushed past the pink rims, over their own helmets, and into the channels. Inexorably and slow they pressed until each man's nutsack was flat against the taut cheeks of a twin's ass.
Fully impaled, Rose and Renee woke. their pussies dripped freely, their nipples tingled, and they were unable to keep their pelvic muscles still. Kent and Arthur began now to rhythmically pull and thrust their cocks inside Renee's and Rose's rectums.
Grunting under the pressure and moaning with pleasure, the twins clasped each other tightly and kissed. Passionately they probed each other's mouths with their tongues and nipped each other's lips with their teeth.
Kent and Arthur increased their speed and depth and the girls clenched their anuses, grabbing, holding, asking the cocks to tarry longer. At last, the men accepted their begging invitations and shoved home, erupting and dissolving. Rose and Renee screamed ecstatically, "OH MY GOD! OH! OHMYGOD!" as their own orgasms rolled through their shuddering bodies, curling their toes.
