A few evenings later, Kim found herself home alone with Hulk. The rest of the family had gone out to a movie but Kim had stayed home, feeling horny and wanting a chance to be alone with the big Doberman Pinscher.
The instant the family left the house Kim tore all her clothes off. Then she called Hulk into the bedroom she shared with her sister and gave him the command to roll onto his back.
Hulk eagerly obeyed, his cock already growing hard and sliding out of its furry sheath. The animal realized that something sexual was about to happen between the teenager and himself.
"Oh, Hulk, you really turn me on!" Kim cried as she knelt on the floor next to him. The dog was flat on his back with all four paws in the air. Also sticking up in the air was his stiffening prick.
The young girl gave a little groan as she leaned over and began to kiss the dog's furry belly. She felt his muscles quivering against her lips, and she began to tremble with excitement. She knew that, as always, Hulk would let her do anything she wanted to him. And he would do anything to her which she commanded. Such unquestioning subservience aroused her and she felt a tremendous sexual power.
Kin shoved her nose under the Dobie's huge balls, absorbing his musky aroma into her lungs, rubbing her nose against his velvety crotch. Hulk whined with pleasure.
"Oh, God, Hulk, I have to suck your ass!" she cried. She used both hands to spread the animal's asscheeks wide apart. She drove her nose and lips between Hulk's asscheeks and glued her mouth against his puckering bunghole.
Hulk barked excitedly. Kim licked his ass with the tip or her tongue, teasing the tight little ring until she felt it relaxing. Then she wiggled her tongue up inside his shit-chute.
The dog barked loudly several times. Kim could have sworn that he was begging her to ream out his asshole. Twisting her head and bur rowing her nose and lips deeper between the Dobie's asscheeks, Kim forced her tongue in until the roots of her tongue ached.
Hulk whimpered and his asshole squeezed the teen's tongue rhythmically again and again. She pistoned the full length of her tongue in and out of her dog's asshole, fucking him hard and fast. She often ate out Hulk's asshole but she never tired of the forbidden, tangy taste.
The Doberman was still on his back, but he managed to shove his ass back and forth, impaling his asshole on the girl's tongue. Kim tongue-fucked the dog's asshole again and again. She stopped only when she guessed he was about to come. She zipped her tongue out of his shit-chute, thinking that, although she wanted him to come, she wanted him to shoot his load up into her asshole.
She began to pant as she eyed the dog's magnificent cock wagging and throbbing in the air, a little pearl of pre-cum dribbling from the mouth of his piss-slit.
Kim gave a little squeal of joy as she got on all fours, wagging her ass invitingly toward the dog. Hulk bounded up and sniffed his mistress' ass-crack. He whined with excitement and his dog-cock grew still harder and fatter.
A rush of hot tingles flooded the teenager's asshole as she felt Hulk's wet nose. Her cunt contracted, letting a trickle of cuntjuice down her inner thighs. She squirmed restlessly, hoping she would not come until her dog had buggered her ass and shot his load.
Kim lowered one hand between her legs and dipped her fingers into her moist pussy. She sloshed her fingers about in her fuck juices, thoroughly wetting them. Then, she pushed Hulk's nose away from her ass and stuck those juice-soaked fingers into her ass-crack. She ran her fingers up and down the crack and then shoved one of her fingers into her asshole, completely lubricating the tiny hole which would soon be stretched to the limit around Hulk's fat cock.
Watching her, Hulk whimpered with anticipation. This was by no means the first time the Dobie had seen Kim perform this little ritual. The dog was well aware that within minutes he would be called upon to ram his stiff prick into that tiny little asshole which appeared to be winking at him. His entire black body trembled. Again, moaning softly, Kim lowered her hand to her pussy, scooped up all the fuck juices she could and slid her fingers up and down her asserack. This time, her middle finger easily slipped into her asshole. She spread her fuck juices up and down her asscrack, clamping her ass-cheeks around her sliding fingers in her sexual excitement.
As she lubricated her asshole and asscrack, she deliberately turned her ass up so her dog could watch the exciting motions of her fingers, so he could see her middle finger slowly twisting in and out of her asshole.
Hulk barked excitedly. Kim laughed hoarsely as she leered at him over her shoulder, delighting in the way his mouth hung open, the way his tongue lolled out, the way doggy drool spilled off the tip of his tongue. She could see his entire body trembling and his cock jutting out stiffly and she moaned again.
The dog's magnificent prick stood up hard, throbbing and quivering, the veins along its shaft distended with lust.
"Come here, baby," Kim cooed now, turn mg to face the dog. "Let me grease your cock too."
The dog moved closer to her quickly, his cock wagging under his furry belly. Again, Kim dipped her fingers into her wet pussy and now she reached out to smear her juices on Hulk's black cock. His intense gaze seemed to burn into her as she lubed his prick.
Kim closed her wet hand around his dog-cock and lubed his prick, from base to head. She felt little tingling and prickling sensations flood through her throbbing asshole.
"Ohhhh, Hulk," the teen moaned as she spread a good amount of juice on his prick knob. She could not resist dipping just the tip of her index finger into his gaping cum-slit, and wiping out a sticky drop of cum.
The teenager knelt hornily before the big-cocked dog, her asscheeks quivering before his lust-glazed eyes. She looked back at Hulk over one shoulder and felt her breathing quicken. His breaths were steaming out from his flared nostrils. His eyes were rolling back in their sockets. His furry flanks were shuddering violently. He leaped up on her back with his forepaws and sawed his greased cock up and down the crack between her asscheeks, his head flung back and a howl of arousal coming from his doggy lips.
Kim groaned and she reached back feverishly for his pulsing prick. She had to get that fat cock into her ass or she would die with lust and sexual frustration. And she had to get his cock into her fast before Hulk lost control and came all over her back.
"Hurry! Fuck me, Hulk? Fuck my ass!" she cried frantically, trying desperately to get a firm hold on the Dobie's slippery prick.
Gripping the huge dog-cock as tightly as she could, she managed to bend his prick down until she felt the broad cockhead pressing against her shit-chute. Then she took a deep breath, braced herself, and arched her back so her ass was turned up for deep penetration. She wiggled her horny ass against Hulk's cock. Her asshole throbbed with anticipation. Her bowels sizzled with bestial desire. Hot juice dribbled out of her cunt and slid down the insides of her naked thighs.
She felt the Doberman's claws digging into her flesh as he pushed forward. His cock ground against her asshole, his flaring cockhead stretching open her tight ass-ring. It was a tight fit, as always, but the cuntjuices she had smeared all over her asshole and the dog's prick greased the way in.
"Yesssss!" Kim screamed. She felt the dog's entire cock sliding into her asshole in one smooth movement.
Hulk howled, hugging the girl's body against his as if he would never release her.
"God, yes!" Kim gasped, seeing stars before her eyes. Her asshole felt as if on fire around the stretching, invading prick. Every single bit of her assflesh felt swollen with pleasure. She felt hot sensations radiating out from her ass and coursing through her loins. Even her tits were affected. They grew firmer, larger. And her nipples pulsed furiously, as if they might explode any second.
Kim leaned forward, bracing the palms of her hands on the floor and turning her ass up toward the big cock penetrating her. She wriggled her ass back against the dog's warm, furry tummy. She felt the fur around the base of his cock tickling the stretched-out edges of the asshole.
"Ohhhh, you're all the way inside my ass, Hulk! That's it! Now fuck me hard and fast and make us both come!" she demanded.
Her tits hung down, and she rested her head on her arms, feeling her nips pulsing with excitement.
The Doberman clung to her, bent over her and nibbled her back and neck. He licked everywhere his flopping tongue could reach, his wide, wet tongue leaving trails of doggy saliva all over her naked flesh.
"God, Hulk!" the young teenager cried, feeling the dog's big cock flexing inside her, nearly lifting her off the floor.
"Fuck me, you horny Dobie dog! Fuck the shit out of me with your huge fat cock! Use that big cock of yours like you know how to do! Yeah, fuck meeee!" she wailed, feeling her ass burning.
She groaned and caught her hard nips between her fingers, twisting them brutally. As the dog fucked his thick prick back into her asshole, a gasp of pleasure exploded from her lungs.
"Ohhhhh, Hulk, yesss, fuck meee!"
The dog eagerly fucked the full length of his cock in and out of the teenager's shit-chute. He felt her assmuscles tightening around his cock, and he barked with pleasure. His furry tummy and chest slapped against her rhythmically as he fucked his prick in and out of her asshole. He was glued to her ass, biting and licking her back and neck. His tongue washed all over her, making her naked flesh glisten with doggy drool.
A series of animalistic grunts escaped the dog's throat. He panted and whimpered hoarsely, the sounds mingling with Kim's own noises of pleasure. She was breathing raggedly and groaning continually now, thrilling to the lewd sensation of having her little asshole totally stuffed with dog-cock.
Hot tears blurred the girl's vision. She tugged at her tits, pinching her nips, as Hulk continued to fuck her ass.
She thrust her ass back and forth, her tight rubbery asshole gripping the animal's prick. She felt the warm furry pressure of his strong body on top of her, pressing against her back, and she trembled with excitement.
She pumped her hips back and forth, sliding her asshole on the Doberman's cock as he impaled her again and again. The sounds of their forbidden fucking filled the room about them. The slapping of Hulk's furry belly against Kim's upturned ass. The squishing of his greased cock inside her juicy asshole. The girl's moans. The dog's barking and whimpering.
Hulk whined as he fucked in and out of his mistress' ass with smooth, rapid strokes. He was bringing both of them closer to orgasm. His cockmeat burned the sensitive walls of Kim's asshole.
"Fuck meeee! Fuck me, Hulk! You're fucking me so Goddamned goooood!" Kim cried with animalistic joy. She felt as if her cunt and asshole were both burning up with lust and pleasure. Her entire body felt weak in her dog's grip.
The big dog howled. Kim shuddered at the sound and at the feel of her dog lover's steamy breaths against her neck. He sank his sharp fangs into her tender neck.
She howled with pain and pleasure. "Harder, Hulk, harder! Fuck me harder, you sexy dog!"
The dog barked. Understanding his mistress' command like the well-trained dog he was, he began to fuck his hard prick faster and harder inside Kim's asshole.
"Ohhhh, God, yesss," she moaned, clenching the dog-cock with her assmuscles, shuddering all over when she felt the meaty cock pulsing violently against her asswalls.
As Hulk pounded her asshole still harder, Kim felt her body beginning to scoot forward on the floor. She only hoped that both she and her dog would come before the animal fucked her right into the wall opposite where she crouched on all fours.
"God, it's good, so fuckin' good!" Kim grunted under the weight of the rutting Doberman. "I'm gonna in a minute, Hulk! Let's come together!"
The big dog writhed against his mistress' back and ass as he continued to thrust his swelling cock deeper into her asshole.
"Yeeeeee!" Kim cried, tears of ecstasy filling her eyes. She continued to hump back. Each time Hulk shoved his hips forward to impale her ass on his prick, she thrust her hips back to meet it, her asshole eagerly swallowing every inch of the hard cock.
The dog's cock lurched wildly against the tensed walls of Kim's asshole. She felt a violent shudder pass through the entire length of the skewering dog-cock.
Dee knew that the dogie was about to come inside her and she went wild with excitement.
"Do it, Hulk!" she screamed. "Cream my asshole! Come! Shoot!"
Responding on cue, Hulk came. Wads of creamy dog-jism flooded the walls of Kim's ass, filling the tiny hole to overflowing.
"Oohhh, yessss, Hulk, you're coming so hard and fast inside my ass! God, it feels good! More, Hulk! Keep shooting!" Kim yelled hysterically.
She felt the thick dog-spunk backing up, flowing out of her cock-stuffed bunghole and creaming the backs of her thighs. Her thick cuntjuices ran out of her pussy to meet the dog-cum, mingling and pooling on the floor between the teenager's spread legs.
Again and again, Kim squealed with delight at the feel of her dog's creamy cum filling her all up. She savored the obscene sensation, moaning again and again. She could actually hear the dog-jizz splashing into her ass and she quivered at the lewd sound.
As Hulk continued to come, his cock flexed so violently inside her ass that Kim found herself being lifted up and down by the big spasming cock. She felt her bloated pussylips shuddering, her clit twitching, and every single inch of her pussyflesh quivering and she knew that her own orgasm was only seconds away. Finally, as the dog-cum continued to pour into her bowels, Kim came.
"I'm coming, Hulk!" she gasped. "I'm coming with you."
A growling sort of moan came from her throat as her pussy convulsed powerfully. She shuddered uncontrollably, her body jerking back on the animal's rutting cock.
Kim's bestial orgasm went on for long minutes. She was lost in the throes of animalistic pleasure and she groaned again and again, hearing Hulk howling at the same time as he continued to shoot his load inside her.
