Suddenly she could hold herself back no longer. Uttering a savage little cry of pure desire and release, she reached around in back of herself and grabbed Cesar's long animal penis, pulling it forward so that the tip of it pressed snugly against her tightly clenched little anus.
The big dog slavered and gasped, its haunches still struggling for a firm position in the softness of the bed. His strong forelegs gripped tightly around her naked waist and hourglass hips, his slippery cock sliding effortlessly forward through her tight elastic anal ring!
"Aaaarrrggghhh!" Sharon groaned as the huge instrument began to push away her snugly fitting rectal walls. In spite of the initial discomfort, she pushed her buttocks backward, trying to capture more of the delicious hard instrument. Although this was the first real sexual experience any girl could ever have. His long slender hardness seemed to fill up her very soul as it pushed its way slowly through her throbbing, softly resisting nether hole. The pleasurable sock of being filled up with a dog's large, pulsating animal cock was like nothing she had ever experienced before. Her nibbling anal channel wanted instinctively to gobble it up until it disappeared up inside her belly with Cesar's soft stomach fur bouncing against the marble smoothness of her backside.
"Daaarrrllling!" she whooshed, her breath coming in ragged gasps.
She wiggled backward, trying to impale as much of herself on his wonderfully exciting penis as she could, but the twinges of pain she was beginning to feel forced her to back off it again.
Cesar was relentless, however. Digging into her bare white back savagely with his paws, he grunted, barked, and yelped as he hammered his rigid animal hardness forward into her snug rectal hole yet one more inch.
Sharon's long white hair hung down all over the bed, covering her panting, gasping face. Now that the thicker part of the enormous rod of shaft had entered her nether opening, the feeling was not near as sweet as it had been at first. There was some pain as he spread her tender nether hole with his gradually expanding penis. As moist and slick as it was, it was still throbbing with the hard ridges of his swollen veins, and she could feel every last iota of their savage pulsing pressure inside her futilely resisting passage.
She groaned as the dog rammed forward still further. Now it seemed as if he would split her right down the center. Her belly felt as if it were on fire. Still, though, she could feel surges of animal-like pleasure overlapping the agony of her anal channel being sent asunder. She wanted this, and at the same time she didn't want it. She couldn't make up her mind. It was agonizing, and yet within that agony was a fierce, soul-dissolving sort of pleasure that could not be denied.
Meanwhile, Cesar's saliva was dripping all over her nakedly hunched back, flowing down the indentations along her backbone and into the cleft of her buttocks. Some of it managed to lubricate his wildly pulsating penis, and trickling down the shaft it found its wet way into the crinkled mouth of her anus. As the dog drew back slightly, worming his penis around in her squirming hot passage, the pain seemed to let up and her backside became somewhat lubricated.
Then with one powerful lunge of his haunches, he savagely rammed his long hard penis up into her tightly resisting anus, burying his cock to the hilt in her warm buttery flesh.
"Arrrrggghhh!" she gargled throatily as his enormous blood engorged cock pushed forward into her softly yielding body. He was entirely inside of her now, and with an expertness born of long experience, he wormed his slippery organ around her nether passage to drag harsh, broken little cries of ecstasy from her passion-drenched lips.
That seemed to act as a cue for the passionately enraged German Shepherd, and now he began squirming and fucking madly into the sex-crazed young teenager, ringing piteous whimpers of insane lust from her open and drooling mouth.
His long merciless cock seemed to be growing increasingly within her fire-filled belly, and for a moment the girl thought it was going to plunge in all the way and come out her gasping throat! The resilient flesh of her full, firm breasts rippled and jounced from each jarring impact of his barrage, their pebble-hard nipples rubbing excitingly across the coverlet of her bed. Overcome now with lewd desire, the helpless teenager found herself grinding backward with a mindless lust, pushing the wide-stretched moons of her helplessly upthrust ass cheeks back onto his love-slick penis, its pleasure-bringing hardness skewering wildly up into her passion-inflamed anal passage.
By now almost all of the pain had subsided, and as her slavering animal master pressed forward the final inch of his masterful, all-subduing cock into her aching nether aperture, she found that she was again more happy than she was in pain. Indeed, the pain had evaporated until finally there was nothing but a wondrous feeling of joyous surrender spilling outward from her wildly tingling loins, a feeling of ecstasy and happiness greater than anything she'd ever known in her life! There was a dynamic pressure building in her hotly boiling anal channel that had a screaming, fluid urgency all its own… pressure pyramiding toward an incredibly high level of sheer, unadulterated bliss.
"Ahhhhh… ohhhhhh… daaarrrling!" she sighed. "Fuck me!" she screamed, groaned, and gasped, straining sluttishly beneath her canine lover, wallowing in subjugation and bestial humiliation. His rampaging cock disappeared up into her then came out again with her puckering anal lips clutching it like a child's lips around a lollipop. Then he thrust his throbbing hardness up into her tight little opening again, bringing sharp cries of ecstasy from her open mouth. She gurgled and gargled and thrashed beneath his inhuman maddening fucking that had destroyed all her reason.
Sharon was vaguely aware that she was straining her lewdly upturned buttocks back over his punishing cock in obscene cadence with his blissfully lewd pumping of the churning inferno up between her trembling white thighs. The thirteen year old was sure of little more than that, as she undulated her hips back toward him in small, pleasure-seeking circles… actually abandoning herself totally in the breathtaking fucking she was getting in her rectal hole. Her beautiful head flailed wildly, her long, disheveled platinum hair flying back and forth. Then she twisted her wantonly contorted face, capturing the intense rapture their all-consuming bestial fucking was providing for him. For some reason this seemed to her the ultimate compliment, and she suddenly felt blissfully, wonderfully happy! The feeling in her loins was too great, too beautiful! Why had it taken her so long to find this wonderful moment! There was a tremendous, ever-expanding balloon in her belly that was blowing up with pleasure!
With growing ferocity, rasping and grunting savagely, the big dog continued to pump his wetly glistening penis in and out of her clasping nether passage, shoving her face sidewise down into the bed with every obscene forward push. Sharon ground her teeth with a mixture of shame and happiness, yearning for him to empty at last his scalding animal sperm inside of her. Her desire-confused brain whirled with the absolute luridness of their situation, while her naked young body trembled in its subservient position to the overwhelming mind-bending sensations he had set blazing in her passion-incited loins. Then her glazed, lust-dragged eyes saw the reflection of their lewdly locked position in the vanity mirror, and she groaned happily at the provocative visions. The animalistic obscenity of the huge German Shepherd straddling the spread white moons of her smoothly curved ass cheeks sent a jolt of unbelievable lasciviousness burning through her erotically quivering flesh.
Sharon gasped as she glimpsed as well the breathtaking sight of his long moist cock emerging from between her whitely quivering ass cheeks, then plunging back inside again. Cesar's whimpering sounds also served to thrill her lewdly as his forepaws struggled to hold onto the smooth curves of her naked waist. With a low throated moan of ardent surrender, the thirteen year old love slave ground her hungrily tremoring buttocks backward over his fiercely punishing hardness, her feverish passion driving her wild!
