The head of his cock nudged into her puckered shit hole, dribbling doggy slime into the brown slot. At the first stroke, it seemed as if that flaring slab of red cockmeat was not going to fit up her tight asshole. His cockhead was a lot wider than her asshole and stuck fast at the entrance.
Then Debby squirmed, relaxing her sphincter muscle. Her asshole fluttered and rippled and parted. The weeping tip of the Alsatian's cockhead nudged into her brown bud. Debby's asshole was already soaking wet with doggy slobber and his piss hole was oiling it further with a scummy seepage. His slick red cock-knob began to slide into her ass.
Frank didn't know what was going on. He was aware that Debby had stopped riding his towering prick and was holding steady on a deep cuntful, and he could see that the Alsatian was clinging to her haunches, but he didn't know quite where the doggy's prick was directed.
Grinning, her face radiant and her eyes aglow, the depraved little teenager whispered: "Oh, Daddy – that horny doggy wants to fuck me up the ass…"
Frank croaked and his prick surged mightily inside his daughter's pussy.
"I'm so naughty, Daddy," she whispered, batting her eyelashes, taunting him. "Ummmm – I want his big prick plunging up my shit hole."
And she proceeded to take it.
Rex humped and Debby shoved her ass back to meet his lunging ass reamer. Each time he pumped it to her, a bit more of his cock inched into her shit chute. The dark folds of her asshole were rippling as they pulled his cock in. Her shit tunnel spread wider to accommodate the bulk of his plunger. Rex heaved in again and all of the flaring red slab of his naked cockhead vanished into her ass.
Her ass ring collared his fucker just behind the cock-knob and Debby gurgled when she felt that fat wedge of hot prickmeat pulse in her ass. Her ass tunnel began to drag him deeper, as if she were digesting his cockmeat in reverse, slowly taking him up her alimentary canal in the wrong direction. His cockhead was the fattest segment of his thick cockrod and it forged a passage for his cocklance to follow as it slid deeper and deeper into those dark and mysterious regions, an unknown cavern where the dog's cock had never before ventured.
Her ass tunnel was tighter than her cunt, but little by little it was spreading around the throbbing contours of his prick. With his cock-knob glowing like a beacon to light the gloomy passage, the dog fucked deeper, working his prick up into her ass guts.
Rex's lips drew back from his gleaming white fangs in a snarl of bliss. Doggy desire caused him to yelp deliriously. His canine imagination could not encompass this human variation – but his doggy prick was managing very nicely. Inch by inch, his cockmeat slid deeper into her ass. He bucked, shoving another hairy inch in. Her shit chute rippled, dragging his cock still deeper into her belly. His smoking hot cockhead slithered into her ass guts and she wondered, vaguely, if that hot slab was floating around in the slimy sea of jism she had swallowed out of her daddy's cock and balls.
Abandoned to depravity, Debby jerked and wriggled, holding all of Frank's cockmeat up her cunt hole as she waited for the doggy to bury his bone.
She wondered if her father would like to fuck her up the asshole, later. It would be a real kick to suck on the dog's prick while Daddy fucked her shit hole, she thought, with gay expectations. Would those two big cock-heads bump together somewhere in the middle of her guts? Even before this first double fuck was completed, the insatiable little minx was already planning for the future.
How happy she was that her mother had gone away for a week, leaving her to tend to the housework!
Rex held steady for a moment, bracing his powerful hindquarters, his flanks heaving. Then he whipped his loins out, and this time every inch of his iron-hard, red-hot prick slammed up Debby's asshole.
Stuffed to the brim in both fuck-holes, Debby gasped. Her daddy's cockhead surged deep up her cunt hole and the dog's bloated cock-knob throbbed in her ass. The two long cocks were pressed together, separated by the slender membrane that divided her twin fuck-tracks, throbbing vein to vein inside her loins. Debby was in seventh heaven. She squirmed, working both pricks around inside her but holding both root deep. Rex's big cock was stretching her shit chute around it as it expanded. It hurt just slightly, the faint ache only adding to the thrill – a new, dark dimension sparking her desire.
Rex began to move first. The frantic doggy jerked his fat plunger out of her asshole, dragging her haunches back on his retreating cock. His fat cockhead was stuck fast in her asshole, swollen so huge now that it would not pull free. Rex was stuck up her ass inextricably, she knew. There was no way she would be able to get his prick out of her shit hole until the doggy had shot his creamy cum and his cockmeat had softened – and no way that she wanted to get him out until she had an assful of dog cum, either.
He fucked in to the hilt again. His hairy balls whipped into her crotch, slapping against Frank's balls. He began to pour the prick to her furiously.
Debby's thighs tightened. She shoved back to meet the dog's ass reamer as he fucked in and then, as the brute withdrew, she pulled her pussy up her daddy's cock, to the knob. Frank heaved up from the chair, falling into rhythm with Debby and the doggy, joining into the tempo of this frantic three-way fuck.
Frank's prick filled her cunt. Then, as it pulled out, the Alsatian's cock plunged up her asshole. Inside her loins, those two steaming engines were passing like locomotives on twin tracks in a dark tunnel.
Debby was buffeted between them, jolted on a cunt-stroke, rattled on an ass-thrust. Her hips flew wildly and her slim belly pumped. Her ass thrashed and churned. She changed the tempo squatting down onto a cunt hole full of pounding prick as the dog fucked balls-deep up her ass.
Frank churned her cream bowl to froth, his body arching and shuddering as he rocketed his cock up from the chair, and Rex fucked her ass in a frenzy. A thick human cock hissed up her slippery fuck-hole and a long doggy prick pounded like a hammer into her ass guts.
Debby was so hot that she couldn't tell if she was coming or not. The waves of bliss were lashing through her loins and shooting up her thighs, peaking as high as she had ever known them to peak, and yet they were getting higher and rushing through her faster with every fuck-stroke. She was creaming, yet there was no ebb to follow the crest. No sooner had she shuddered with a bone-rattling climax than she surged right up to an even more violent spasm. Her cunt hole was melting on her daddy's prick and her ass seemed to be creaming on the dog's rampaging cock.
Frank's cock plunged up her fuck-tunnel so far she thought she could feel it flare in her gullet, and Rex's prick sped up her asshole so high she thought the knob must be wallowing in her belly, splashing around in her digestive juices. She fairly screamed as another jolt shook her.
"Shoot in me!" she wailed, desperate to have the raging inferno of her loins doused by foaming fuck-juice.
Frank didn't know if his daughter was addressing him or the dog – and neither did Debby, yearning for the steaming hot cum out of both of those huge cocks. Rex, of course, didn't know the meaning of her command. But he was hot, and he shoveled his cockmeat in even faster as he prepared to spill his cum-load.
Debby creamed again, a flood of cunt juice swirling into her cunt hole, her ass guts melting.
Then Rex howled like a wolf and his hot, thick doggy jism hosed her ass guts in a scalding jet. Debby wailed as that slimy enema gushed into her guts in a foaming tide. She jerked her ass back, taking all of the brute's fucker into her ass, then jammed down on her daddy's cock as Frank, too, erupted with a volcanic spurt of jism. His cum steamed into her cunt hole in a raging geyser.
Gliding together like some well-lubricated, intricate fucking machine, man, girl and doggy pumped their fuck-juice out in creamy torrents.
