A commission for SIB: Lots of blorfing!


Life's tough.

That much had always been true for Sib. His body was consistently covered in aches and pains, little bruises and twinges in his muscles. They were a reminder of the previous day's labors. They remained the same every morning.

And yet he was content as he gently wurfed and reached for his alarm. A single finger extended, pressing down the fat button that would silence the monotone shriek.

There was no 'five more minutes'. No curling back under the covers. Sib had responsibilities and he savored the slow morning stretch that got his day started, the wonderful situp and extension of his fingers towards his toes.

The press of his muzzle against his comforter as he kissed his own nuts good morning.

Being a six foot tall red husky stacked with muscle, most people didn't expect him to be flexible. Truthfully, he wasn't. The only reason he could reach his churning boys was a combination of the foam pad placed underneath to keep his blood flow regular and his beachball testes' sheer size.

His flaccid member throbbed as he reclined from his own attention, giving a pleasant pulse up his spine.

"Oh that feels good." He murmured, feeling his dick twitch in agreement. Half mast and draped over his nuts like a fleshy tree trunk, Sib was about to pull himself out of bed when a rounded shape pushed against his left nut. The flesh domed outward, visibly distended from a mass within. A thick tail lashed at his walls next as the bulge disappeared.

A practiced hand pulled off his covers while the other slapped the call button for his favorite nurse. The sensation spread again, jerking his fat dick upwards as his tongue lolled from his mouth. That same mass thrust itself into the root of his testicle, almost violently stretching his fibrous spermatic cord with its presence.

The man groaned as he rose, as he carefully looped his arms around his nuts and hoisted them. Around his bedroom were mirrors, carefully placed at the proper angle to see the underside of his bloated sac. There he watched the mass struggle and tense, pounding his brain with bliss as it shoved itself into his body.

With a creaking, audible slurp, Sib felt it slip inside his prostate and grind the organ from within. Helpless, he held tight to his junk, riding the spasms that curled his toes and forced his hips to buck in purest instinct.

And yet the mass in his prostate refused to move. The thing's whiplike tail lashed, tugging his testicle left and right, bloating the passage with semen as it struggled to move. He was about to drop his ballsack with the cadence of pleasure assaulting his brain when the door opened and his favorite nurse eased herself, sideways, through the door.

She was huge. Her belly hung before her, balanced out by a wobbling ass and weighed down by a pair of mountainous tits that could crush a car. Powerful, rippling with muscle with every step she took, her three heads radiated an easy, happy smile that carried to her floppy, flapping ears. All that curvy flesh was carefully, gracefully packaged in the pristine white of a nurse's gown, complete with lacy stockings and garters. She bent low as she immediately saw Sib's plight, crawling on her hands and knees, her ten foot tall form barely able to keep her rotund form from touching the floor. A dark tongue parted each pair of lips, licking along them as they savored the sight of those bloated testes and the stretched spermachords, the solid mass in his prostate urging her hand forward.

Her fingers were warm to the touch, and as the pressure built, Sib's head swam with lust. His groans slipped from between his lips as his hips pressed upwards, forcing those hands to follow.

Then, his tortured flesh finally yielded. His prostate deflated as the massive sperm was forced into his urethra. His cock, throbbing with need, as thick as a tree trunk, distended around the squirming mass. The belly of his breeding tool swelled with fresh semen, much smaller siblings building up, welling behind that obstruction. His nurse's hands rose to squeeze it, the flesh warping like a waterballoon as she carefully pushed. The pressure made him cry out, both forcing the one massive swimmer further along while the rest blackflooded into his aching ballsack.

Shuddering in sympathetic bliss, his three-headed nurse kissed his tip. Her lips, soft and wet, suckled slowly, drawing upon his skin and toying with his needy cumslit. Her reward was a lethargic throb that pushed against her snout, that smeared a layer of slimy precum over her snout.

The mass in his cock pressed forward. The flesh of his meat quivered in anticipation. Finally, the tip of that football-sized sperm breached the entry to his member, a thick white shell that comically stretched his tapered cockhead to the point it looked like a bulbous knob. The nurse was too polite to giggle or laugh, only lowered her central head and gave one last suckle, her teeth sinking into the exposed sperm's tip before he drew her head back.

The flood was biblical. Off-white sperm splashed over her gargantuan tits and over her swollen belly, soaking her clothes with the husky's virile essence. She paid no attention, only tilted her head back as the oversized sperm continued to lash against her, tail whipping her tits and shoulders as it tried to move forward, only for her jaw to relax and let gravity pull the entire thing down. Her left and right heads moaned as the center throat stretched, the sound quickly twisting into a pleasured panting as the sperm finally found the hole it was searching for. Down it went, distending her neck before disappearing beneath her collarbones, the still-squirming tail slurping between her plump lips like a noodle.

A cloth, clean and untainted, filled hand and dabbed her central lips while the left head cheerfully spoke in her deep, husky voice. "Good morning, Master Sib. Are you ready for today's appointments?"

His response was cut off by a soft groan as her hands gently massaged his bloated testes.

"You're going to have a rough workout today, and your boys a little underfed. I'll be sure to prepare your breakfast with a little extra today."


The protein shake had tasted wonderful, filling up Sib's belly. Not that he was Sib right now. He was Sib Husky, MD. He was a professional. He was checking a patient's throat.

Of course, one might think the panting and moaning meant otherwise.

"Hypersensitivity of the tongue and mouth." He noted carefully. His curled tail wagged as he explored the woman's wide mouth, savoring the texture of her scaled lips before it transferred to the tender flesh of her mouth and the broad, tender meat of her tongue.

That broadness terminated in two tips that were greedily pulling at his fingers, trying to coax him in as her throat danced.

Only when he pulled away did the fog in the serpentine woman's purple eyes finally clear. She felt the drool sliding down her neck and withdrew from his gentle hands. Her cobra hood collapsed around her suddenly timid expression. "I'm sorry, Doctor. I don't know what came over me."

Sib chuckled, his paws moving down her sides, tickling her smooth scales before resting on the wide flare of her hips, the union of her body to the coiled mass of muscle that was her lower body. Those curves had only been forced wider over the last few months, stretching her out to proportions that would be almost comical if not for the gravid weight hanging from her midsection. Taught, bloated, and round, lumpy with the shells of her young, the snake gave a surprisingly feline mewl once the doctor's hands slipped back up to hold her heavy dome.

"I can tell you exactly what's wrong." He said softly. His fingers rubbed slow and tender circles into her strained belly scales, making her tailtip lash from site to side. He paid it no attention as he cupped the breasts that hung from her chest. Not the first pair, or the second, but the third, smallest ones. A gentle squeeze forced the woman to try to withdraw, instinct fighting her need to know more. "You've not been eating properly."

"But I've been eating all my fruits! And veggies too!" She whined. Like a chastised child, she retreated further into her natural headdress, pulling the lips of her hood around her mouth. "I've been doing everything right, I promise!"

"You've not been eating your protein!" The doctor answered. His forefinger pressed against her snout, and for a moment the woman's eyes became lost with the same hazy pleasure that had taken her before. She followed the digit wherever it went, her meaty tongue flicking out to stroke the offending finger as her saliva began to dribble once more. "I know you're trying to go vegan, but you're a hybrid, dear, a combination of mammal and reptile. You need that protein for your children, and so these gorgeous breasts of yours swell with milk."

"But, where?" Her words slurred as she lost herself in the touch of his fingerpad.

"Aside from at least drinking milk and having a good steak or two every now and then?" He smiled and cupped her cheeks. His cold nose touched her own and broke the hazy trance with its presence. "Well, does the mother of my babies really need to ask?"

The serpent blushed yet again, then squirmed as she felt the throbbing heat that pressed between her coils. She gasped, a thin, sticky drool coating her belly as the doctor's cock presented itself, as the massive rod slipped upwards and along her gravid stomach.

"Y-yes, doctor." She cooed, unable to help herself as she turned her upper torso towards the heat sliding along her form. Thick as an elephant's leg, it pressed between her breasts, parting them slowly as the gooey richness poured from the very tip with every throb. She giggled as she watched his tail wag, his tongue hanging out as he panted like the breeding stud he was.

Her lower body unwound, then reassembled itself around him, gathering her Sibby close. Her scaled lips caressed his muzzle as his shaft pressed higher along her body. Her tongue forced itself into his throat, stretching it slowly as she whined and quivered in excitement, only to feel the tip of his dick against her throat. Admiring the sensation of that sexual weapon, she pulled away with a deliberate stillness, messy strands snapping in the air between their once-locked lips.

For a moment she considered slamming her wet vent down onto that throbbing spire, but doctor's orders said otherwise. Her tail wound around his legs and hips, holding him still as her mouth found his member. The first suckling kiss filled her mind with heavenly bliss, only for the second to make her heart somersault within her chest. She needed him, was desperate for his touch, and she crooned in blissful agony as she finally felt his thumbs on her nipples. Perky and hard, the electric sparks of his touch caroused her very soul, forcing her to gasp and jump in his grasp, her mouth parting from his dick only to descend once more.

He was big, bigger than any male had a right to be, and yet she hungered. Her mouth stretched, her jaw moving with it, flowing like water as she eased her union away from his hips, as she straightened herself before him. She fell upon his spire a trembling heartbeat later, using her entire upper body to engulf her Sibby's cock. Down she went, feeling her body stretch to enclose him, to satisfy her needs with his turgid length.

Finally, her nose ground into his pubic fluff. Drunk from his scent and his taste, she could barely comprehend the way her body yawned wide for him, the way that his tip pressed into her lower form.

She was merely grateful that her stomach was in her lower half as she felt hm twitch, as he raised her hands to longingly stroke his overburdened spheres. His moans were sweet music, and her cheeks swelled wide as his knot pressed into place behind her lips. Tied and helpless, she took deep and needy breaths through her taxed nostrils, only to gag and squirm as the beastly doctor's dick began to pound and pulse.

The gravid nuts in her hands tightened. The flesh tensed and the fur bristled. His throaty, growlign moan caressed her ears as he sank his fingers into her coiled tail.

Breathless, the snake twitched as she felt the beast inside her grow even larger, rippling with strength and carrying her back and forth with the pressure within. Then, the dam broke. Her belly distended with messy load the doctor prescribed. His semen painted her insides as she dutifully swallowed. The taste restarted her lungs, making her gasp, then quiver as another salty stream gushed into her lower half.

Bloating, distending, she was forced to release her captive lover from her lengthy form. The pressure soon became too much and she withdrew, desperately coughing and swallowing from the fullness that ached so wonderfully inside her.

And yet the husky's cock continued to pulse, continued to pour his essence over her. Ropes of semen splattered against her face and over her belly, marking her in his sexual scent. Stupefied, she could only watch as the mess pooled at his ankles, rising up to mid-shin as he continued to bathe her.

Then she lost her grip on his cock and the next jet splattered the ceiling, smashing the light and shrouding the room in darkness. Her fingers found her snatch and began to play with her petals as his emission rained down onto her. She quivered, instinctively scooping handfuls of his spunk into her waiting sex. The touch of his semen was purest ecstasy, and a moment before she could shove her hand into herself, she felt her stud's dick tip between her folds.

There was no thrust, only the loud, glurping sound of a fresh load forced into her tunnel and the sensation of being seeded. She shrieked, her pussy clamping onto his tip, and let her fluids squirt across his throbbing dick in an endless stream.

--

Rooti waited and watched the door. Her scaled, furless tail wound around her leg in agitation as she tried to consider where she was, and what she was even doing.

She had smelled it, from the second she stepped into the building.She had smelled it on the three headed wolfess at the front desk. She had smelled it on the vixen walking down the hall.

She smelled it in the room she now sat, coating the walls, the floor, the ceiling!

Semen.

Everywhere, no matter how she turned her two heads, she couldn't escape the scent, or what tricks it played on her mind. Every fiber of her being wanted to leave, to run down the street screaming. She didn't care that her clothes were in a folded pile in a chair on the corner, she needed to escape. Every rational and instinctual part of her brain told her she was in the breeding den of a predator that would happily fuck her, then eat her. Or maybe both at the same time.

Those same instincts had pushed her to stand, and she was about to jump towards the door when the knob twisted.

She fell back down, hands in her lap as she accepted her fate, as the red fur of a well-muscled husky slipped into the room. Despite the pounds of muscle, his expression was almost dopey and eternally happy, the kind that made her want to smile as he introduced himself as Sib Husky, MB.

Of course, her nose wrinkled slightly as she realized the smell that radiated from him was the same as the room around her. Her heart began to race in fear again as she started searching for a way out, a way past him, her two minds working in tandem to formulate an escape. She couldn't slip between his legs to get out, his ponderous cock and balls were on full display, but she could maybe jump over him. Six foot height didn't mean much if she used her examination table as a springboard.

"Miss Rachael Carmell?" He asked, snapping her from her thoughts.

"Yes!?" She squeaked in turn.

He drew a stool over, using a cum-soaked foot to do so. The sight of it made Rooti blush. But not as much as the way his bloated ballsack pressed against the floor once he sat down. "I was saying that Nurse Cyn tells me this is your first time here. Can you tell me the problems you're having?"

The husky's tone made her pause. He looked genuinely concerned, his eyes soulful and bright. For a moment she considered simply walking out, but was caught in that moment of indecision.

The doctor patiently waited, ears cocked and at attention. The two-headed mousegirl silently hoped that he would give up on her from the outset, that he would walk away.

Instead, he pulled a clipboard from a nearby counter and read through the contents. In the silence, he started to scribble, started to write. Doubtless, he was already coming up with ideas of how she was broken. How she was useless.

Instead, he offered the clipboard to her and tapped on the corner. He had made a grid. "Do you want to go first?"

The next hours passed in a blur, the two passing the clipboard back and forth. Game after game, draw, defeat, and victory, they passed the panel back and forth. The nurse from the front slipped in, gravid and heavy, and handed the man a protein shake. Then came back later to do it again after three hours.

Finally, the last played out, and she sighed to herself as she resigned to her fate. She liked this doctor. He didn't push the issue that she had come in for. Doubtless he already knew, the nurse had pulled a tiny bit of blood for analysis while she was waiting.

Infertile.

The word was almost assured. She had had so many boyfriends, they wanted children, and she couldn't deliver.

She pulled her knees up against her chest, unable to care that the short hospital gown rode high and displayed her sex. "I'm sorry for wasting your time today. I should go."

"Hardly!" The doctor smiled. His tail waggled and, in that moment, the two-headed woman was reintroduced to his obvious lack of pants. "We were having a load of fun. No problem in that."

"Yeah, but you're just doing this with me to soften the blow. I already know I'm infertile."

"Infertile?" He raised an eyebrow, then sighed as he scooted closer. "That's not the case, Miss Carmell. You're just resistant."

The mousey woman's sad frown turned into a scowl. "Don't toy with me, doctor. I know what I am. I've gone through at least ten boyfriends who wanted kids. I couldn't deliver for any of them."

"Yes." He nodded once, "But that's not the issue here. The only question I ask is: Do you want to be a mother?"

"More than anything." Rooti quietly whispered. Her hands covered her eyes as she felt her soul leaking out from behind them.

She didn't expect the hug. She didn't expect the deep and soft fur that swallowed her up. She didn't expect the feeling of those broad, strong arms around her shoulders.

She didn't expect to feel his cock against her nethers.

"Performance anxiety can peak in some women." He said softly. His tip throbbed as he pressed against her, as he slowly rolled his hips to better introduce her to his girth. "Sometimes it shuts down their ovaries."

"So I'm broken." She whispered softly. Her heart felt fragile, weak.

Only to be buoyed by a soft kiss along her right head's ear.

"Not at all." The doctor murred into her ear. His hands found her buttox and pulled her close. A moment later he was back on his stool, and his massive, bloated testes had formed the perfect seat for her to rest on. "It's surprisingly common. So let me, a professional, help you."

"I thought you were a doctor." She stammered. She felt his member ease between her petals, slowly stretching her folds. This didn't match what she had come to expect. This wasn't the rough and rapid ride of a male that wanted to breed, this was something else entirely. It made her belly flutter.

"I am. I'm a Breedologist." The husky's lips moved down and caught her lips. The kiss was slow and tender, matched only by the careful, rising thrust between her legs that made her diminutive tits bounce against his chest. "The MD stands for Massive Dick."

Rooti laughed. It was honest and playful, and it shimmered in Sib's ears. He groaned at the sound, pulling the woman down by her hips as his cock slowly spread inside her. Small and delightful, she bounced readily in his lap, her lower lips warm and soft, her insides squirming with every impact of her meaty rear against the husky's balls.

She needed him. Every inch of her body yearned for him, so she whimpered in delight as he carried her to the ground, as he buried her under his fluff and ground his meat inside her sex. The lewd slaps of his balls against her rear filled her ears, her form aching, yearning for more while her fingers dragged down his back. A need sparked inside her belly, something she had never felt as his thickness found her G-spot and pulverized the tender patch with every thrust.

And then his tip kissed her cervix.

She squealed, the sensation new and filling her with a quiet desperation. Her hands looped and locked behind his neck, tugging him down as his pace doubled, as the meaty slaps of his breeding made her cry out in terrified lust.

She wanted this. Needed this. Her two heads found his shoulders and bit down, marking him with painful sucks and kisses as her insides twisted. She felt the fluids inside her gush outwards a moment before a fist of lightning smashed her brain. Delight coated the world in its pink haze as she came, as she tightened and squirmed like a feral beast beneath her breeder, trying to understand the sensations coursing and striking inside her form.

But Sib wasn't done. He continued to pound at her form. His hand found her tail. Winding it twice around his fingers, he jerked her back, using the length as a handle as he hilted again and again, his knot spearing her folds with a pop, then pulling out with a spurt of fluid, only to jam back in.

Like an animal, he growled into her ears, breeding her like an animal, fucking her with his knot as her muted screams coursed into his flesh.

Only to jam in one last time, the belly of his breeding rod distending as his testes tightened. Her insides twitched and spasmed, weary and tired from the sudden surge of motion. So tender, she could barely breathe as she felt that member bloat and distend, filling inside her like a balloon, only for his tip to yawn wide against her cervix and pour his essence against her inner chamber.

Again and again, she felt his orgasm pour into her. She felt his testes twitch against her rear. She felt full, and a hand slid down to touch her tummy, finding the space just above her pelvis paunchy and swollen, swaying with the weight of his emission.

Groaning, he pulled from her sex. Immediately his hand slipped down, pulling her pussy lips together to hold his seed inside. The nurse appeared, and the sticky kiss of electric tape touched her labia, the weight of the material distracting her from the other woman's ethereal retreat.

Rooti continued to hold the male in her deathgrip, unwilling to release him as he groaned against her necks. She wanted him there, and twitched as his semen painted her ass, the thick ropes wasted on her thin buns as his hands pet over her sides.

The weariness that finally claimed her was deep and satisfying. His lips caressed her cheeks, and with a sigh the massive husky felt her jaws unlock. He contemplated whether to wake her, but decided, as a rope of his seed poured over her chest and belly, to allow her to rest. There were beds in the back rooms, and a fridge of food and water for when she woke up.

He could go over her new diet and supplements later.
