It took the powerful young man a second or two, but he managed to re-gain control over himself, and he began fucking his long thick cock in and out of Niven's thin-stretched lips, always leaving the hot swollen tip half an inch inside her mouth as he began to guide her head with his fingers wrapped tightly in her hair.
Not that he needed to give her any help. Niven loved sucking his penis almost as much as she loved having it fucking up into her cunt, and she moaned passionately as he speeded up his deep, inward thrusts. His heavy, cum-swollen balls swung up and slapped against her chin, the thick, coarse fuzz covering them tickling like a light airy feather, and she fought to keep her breath, catching small gulps of air on each outstroke.
Martin gleefully watched the puffing out of her cheeks beneath him as her head bobbed on the end of his skewering penis. He knew that she loved doing this to him. His grin widened with each deep thrust he made into her willing face, and her moan of arousal drove him on to even deeper fucking motions.
Then he heard Siegfried whine, and for a moment, his attention was arrested. Hell… there was no reason why the dog shouldn't be getting his jollys as well.
"All right, Siegfried… fuck her. I think she's about ready for your cock!"
Both Niven and the massive dog stiffened at the words, and Siegfried hurried to claim his reward of patience. For a moment, Niven removed her mouth from her boy-friend's cock as she waited for her wonderful dog to mount her. She shivered sensually as she felt his cold wet nose brush exploringly up against her tingling cuntal lips, and she waggled her rounded buttocks invitingly back toward Siegfried's huge furry head to meet the long pink tongue that suddenly snaked out and licked wetly up and down in the valley between her ivory white, upthrust ass-cheeks. Uuuuuuuummmmmmm… Again she felt the long length of hot wet flesh touch her and she felt him beginning to lap greedily at the opened tight fissure between her wide-spread thighs. He ran his tongue wetly through her sex-drenched loins, from the tip of her puckered little anus up over the fluted edges of her vaginal opening, sometimes reaching below to the tiny jerking bud of her clitoris. His skillful thick tongue cut moistly through the soft, sparsely fleeced pussy lips like a keen blade. It laved relentlessly between her quivering thighs, pausing occasionally to dart and plunge deeply into her.
Niven knew that this was definitely the proper way to start the day, and if that ass-hole next door was too simple-minded to understand that, than he deserved the worst that could happen to him. Damn! He was actually punishing his wife by leaving her alone like that… just running out of the house without fucking her when she wanted him to. If Martin ever did something like that…
But suddenly all coherent thought faded in a blinding flash of excitement as Siegfried's ceaselessly exploring tongue shot out and up into the moist channel of her naked cunt, deeper than any human tongue… even Martin's… could possibly go! As her whole body tensed and quivered wildly from the glorious sensation, she sucked harder on the huge fleshy penis in her mouth, reaching up with one hand to cradle the sperm-heavy testicles that slapped against her saliva-coated chin.
Martin sat back, feeling completely at ease as Niven began to put her heart and soul into the sucking of his cock, running her pink tongue around and around the swollen head, flicking her tongue-tip inquisitively into the tiny open slit of the moist cock-head to taste the sweet lubricating fluids that were oozing out there. As Siegfried's thick wet tongue lashed teasingly up through the open furrow of her tight wet cunt all the way to her clenching rectum, Niven knew that she was fast losing all her reason. She began to lick and suck madly like a demon at the thick, hardened shaft imbedded in her mouth, her lips slimy from the mixture of his pre-cum and her saliva. The thin tensile rim of her mouth clung to his shaft as though held there by some unseen force as he fucked with long deep strokes. The mere thought of his huge cock in her mouth suddenly exploding, squirting its white, thick sperm into her throat had already begun to make her wild with anticipation.
Then suddenly, she heard Martin's passion-rasped voice command, "Fuck, Siegfried. Let's fuck her together!"
Again, both Niven and the powerful dog shivered with ecstasy. The three of them had become a team… like three perfectly working parts of a machine. Niven loved the thought of being fucked from behind by her amazing dog while she sucked and slavered on the cock of her lover. She felt the great animal move forward at the command.
Immediately the huge German shepherd raised up on his hindlegs, mounting Niven with his forepaws wrapped around her full, undulating hips. His powerful hindquarters moved in close between her soft, spread thighs, at the same time shoving forward with his long tapering cock.
Niven jerked forward as a reflex, and sensing that she would, Martin thrust up again, impaling her mouth deeper on his tremendously hard cock. She gagged slightly at the choking entry, struggling to keep her breath. It came as a great rasping sound as she sucked in a gulp of air from the sensation of her loving dog's scarlet penis jabbing out from its furry sheath and slipping wetly into the hot damp slit of her inflamed pussy lips. Niven groaned blissfully as she realized that she had to have as much cock as possible. She wanted the totality of Martin's penis in her mouth, while at that same time taking as much of Siegfried's long, beveled penis into the seething chamber of her cunt as she could. Knowing that her dog would need help, she reached behind her and circled her fingers down through her wide-spread, ivory-fleshed thighs to grasp the slippery length of the rigid animal cock.
Siegfried half growled and half whimpered as her fingers gripped on the throbbing length of his flesh, trying desperately to place the pointed red tip at the mouth of her passion-saturated vaginal opening. In her bewildered, passion-distorted daze, she didn't know if she would be successful or not until the great beast shot up into her steaming passage, his muscular rump driving forward in rapid, jack-hammer thrusts, spreading her moist, burning pussy open wider and wider with every jolting lunge he made into her.
"Uuuuuuuhhhhhh… uuuuuuummmmm… uuuuuuuuuuuuummmmmmmmmmmmm…!" Niven moaned sensually around the big fleshy cock fucking ceaselessly into her mouth as she felt her naked cunt being filled by the long, hard dog penis spearing into the depths of her belly. She could feel her beloved dog's silky hair brushing lightly against her writhing, milky white buttocks as he pistoned his enormous tapered shaft into her tightly contracting cunt. She was impaled to the fullest on the German shepherd's wonderful animal-cock and her mouth was filled completely by her lover's immense human penis.
Martin looked down, savoring the sight of his towering thickly veined shaft buried in his beautiful lover's lust-contorted face. He felt the young girl's hands greedily massaging the skin of his balls as she sucked rhythmically up and down the rock-hard flesh of his cock all the way from the smooth rubbery head to the velvety flesh at its thick base. Her whole supple satiny body quivered from the powerful jolts of Siegfried's plunging cock smashing into her tight clinging cunt from behind. At the same time, the warm softness of her tongue twirled maddeningly over Martin's throbbing cock-head at the apex of each withdrawal. He flexed his buttocks fiendishly up and down, following his every movement while she simultaneously worked her naked globular buttocks in little gyrating circles to match the machine-like hammering of the dog's still swelling cock up inside her seething vagina.
Niven was a writhing mass of sweating, lust-deranged female flesh that begged to have the cocks in her fill her to the brim with their sperm. She ground her buttocks hard back against Siegfried's hairy battering body and felt the tiny rivulets of moisture building up in the crevice between her ass-cheeks, trailing down the backs of her straining white thighs while the mounting pressure in her belly and loins signaled that her rising climax was close to exploding throughout her sharpened nerves.
