Rob sat hunched over the computer, staring intently at the text on the screen. Troubled, he frowned and flipped through a weathered notebook before turning his attention back to the screen. No, this wasn't right. None of it was adding up.

He was conducting research on a primeval incantation that claimed to "meld the love of the soul with the lust of the mind". Such a description was vague to say the least, never a good thing when it came to dealing with magic.

A sigh left Rob as he rubbed his weary eyes and once again began the process of reciting the incantation. The study of magic was much like the rigorous pursuit of science: mind-rending repetition until empirical data could be definitively observed and recorded. Therefore, Rob was in the middle of performing the incantation for the 8th time that day when he was suddenly interrupted.

"Rooooob!" someone cried from beyond the room.

It was a girl's voice.

Rob did not get a chance to react before the door swung open and a gorgeous woman with luminescent sapphire eyes and a waterfall of luscious raven black hair walked into the room. She was wearing nothing but a bright yellow bikini that served to accentuate her already voluptuous figure. It was as if the sun itself had just entered the room, yet Rob hardly seemed to notice.

"Hey Ellie," Rob replied nonchalantly, barely sparing a second to glance at Ellie in her revealing garb.

He was busy rummaging through the depths of his mind looking for anything that could help him better understand the incantation he was studying.

Ellie, whose real name was Ellen but who insisted on being called Ellie, playfully chided Rob, "Come on Rob, you're 19 not 9, stop playing at being a sorcerer and come spend some time with your lonely and might I add scantily clad girlfriend."

"In a bit," said Rob dismissively as he jotted something down in his notebook.

"The weekend isn't going to last forever Rob," sighed Ellie, noticing that Rob was still paying her no heed.

Ellie had invited Rob over to stay the weekend at her house because the rest of her family would be out during the weekend. This meant that they would finally have the place to themselves - a rare occurrence. However, now that Rob was settled in it seemed as if he would rather study his silly spells than spend any quality time with his own, might she add, gorgeous girlfriend.

Frustrated, Ellie huffed and stormed out of the room.

Rob would not be alone for long however, as a blur of black and white fur came bounding into the room.

"Hello Sasha."

It was Ellie's dog Sasha, a Siberian husky.

"Hewwooo," Sasha howled in greeting.

"Paw," ordered Rob, to which Sasha promptly stuck out her paw for Rob to shake.

"I lub wu," replied Sasha, imitating what she had heard other people say to her before.

"I love you too," chuckled Rob.

He scratched Sasha's chin, causing her to wag her tail in delight.

Rob was quite fond of Sasha and dogs in general. They were loyal creatures, and some, like Sasha, could hold more interesting conversations than many of his peers.

Sasha rewarded Rob for scratching her chin by coating his face in a thick layer of dog saliva. Giggling, Rob tried to turn away from Sasha's tongue, but Sasha was having none of it. Only when Sasha had run her tongue over every square centimeter of Rob's face did she finally seem content.

"Woof!" barked Sasha before sprinting out of the room, presumably to go see Ellie.

Rob watched as Sasha darted out of the room, her bounding leaps accompanied by the rhythmic thumping sound of her feet colliding with the hardwood floor. Perhaps he ought to go see Ellie too. After all, the whole point of staying at her place for the weekend was to spend more time with her. Plus, his research was going nowhere anyways.

Vaguely recalling that Ellie had entered the room in a bikini, Rob changed into his swimming trunks and made his way to the pool.

...

It would not be Ellie who would greet him at the pool however. Instead, Rob would be met by something that surpassed even his wildest dreams.

"The name's Elsa," greeted a female anthropomorphic husky.

She grinned at Rob before offering him a flirtatious wink.

"R-rob," stuttered Rob, clearly caught off guard by the site of Elsa.

Elsa was about an inch or two taller than Ellie and appeared relatively human-like with the notable exceptions of her dog-like nose, triangular ears, fuzzy tail, and canine snout. Her entire body was covered in a coat of fluffy white fur reminiscent of pristine, undisturbed snow. She possessed luscious jet-black locks and a set of luminous, ice blue eyes that seemed to hold the devastating yet beautiful allure of winter itself within them. To top it all off, she was wearing Ellie's bright yellow bikini, though it was noticeably tighter when wrapped around her impressive bosom than it was on Ellie. In layman's terms, Elsa was hot as fuck.

"Nice to meet you Rob," she giggled.

With introductions out of the way, Elsa unlatched her triangle bikini top and allowed it to unceremoniously drop to the floor. Sensing Rob's enamored gaze on her now bare chest, she began to strut towards Rob, her plump ass jiggling with each step that she took.

Flustered, Rob attempted to back away from Elsa, but he soon found himself cornered against the side of the house with nowhere to go.

"Bad boy," Elsa whispered seductively into Rob's ear.

Stunned by the events that were transpiring, Rob did not resist as Elsa pinned both his arms against the wall. A surprised yelp escaped him as Elsa leaned in and playfully nibbled on his ear. Rob also couldn't help but notice the sensation of Elsa's unclothed bosom pressing against his chest, which served to rouse his manhood into rigidity.

"L-let me go," stammered Rob.

His voice faltered as he felt Elsa's lecherous gaze molest every square inch of his body. He could almost see the shockingly lewd thoughts that were squirming and writhing around in Elsa's head, just out of sight behind those mesmerizing eyes.

Unfortunately for Rob, his discomfort only served to further arouse Elsa, who continued to hold him in place just to observe his squeamish reactions. Soon Elsa was panting and drooling just like a dog, her face flushed with lust and excitement.

"Let you go?" repeated Elsa incredulously before tightening her grip around Rob's wrists like a vice.

An agonized scream erupted from Rob's mouth as pain engulfed his wrists. Defeated, he stopped struggling and surrendered his body to Elsa's depraved fantasies.

"That's right," cooed Elsa directly into Rob's ear, "bad boys who don't do as they're told get punished." A pause followed before Elsa continued speaking. "Now what are you?"

"H-huh?"

"What are you!?" demanded Elsa as she squeezed Rob's wrists as hard as she could.

"A good boy! A good boy!" Rob intonated desperately, feeling the bones in his wrist bend in ways that they weren't meant to bend. "Please, I'm a good boy!"

Why was she so strong!?

"That's right," affirmed Elsa approvingly. "You're a good boy. Now don't you forget it."

Upon hearing Elsa call him a good boy, Rob felt a flutter in his heart, as if a butterfly of desire had just emerged from its chrysalis. It felt good to be praised, even if it was in the same demeaning way that people talked to a mongrel they saw on the street. Ellie had never praised or complimented him before. She was always mocking him, whether it be for his unenviable constitution or his interest in magic. Rob wanted nothing more than for Elsa to call him a good boy again.

"Open your mouth," commanded Elsa.

Rob did as he was told and Elsa pressed her lips into his. He did not resist as Elsa intertwined their tongues in a disgusting entanglement that threatened to trigger his gag reflex. Elsa was subjugating his mouth with her tongue. He felt nauseous and defiled.

Deep down however, Rob also couldn't help but feel ... aroused. He had never experienced this type of a kiss before, so passionate yet so sloppy in its execution. A true act of carnality that resonated with the bestial part of his mind concerned only with breeding and reproduction. Somehow, Rob knew that with this kiss Elsa had flipped a switch within him and irrevocably altered his psyche in a way that left him solely dependent on her. Rob would not be able to reproduce such a kiss, not with Ellie nor with anybody else. He belonged to Elsa now.

Five minutes passed until Elsa finally evacuated her tongue from Rob's mouth. Her kiss had left Rob lightheaded and weak in the knees. It was only through being pinned to the wall by Elsa that Rob still remained standing.

"You enjoyed that," remarked Elsa with a smirk, "didn't you?"

Her eyes were planted firmly on the bulge in Rob's trunks. There was a visible stain where Rob's manhood was pressing against the fabric, demanding to be set free.

"Y-yeah," agreed Rob bashfully.

His whole body felt like it was a furnace. God, Elsa had gotten him all hot and bothered.

"Alright," said Elsa, pulling Rob along by his hand, "follow me then."

...

Elsa interlaced her fingers with Rob's and pinned him down to the bed by his hands. Her tail was wagging excitedly, telling of her eagerness to live out the perverse fantasies that resided in her brain. She had led Rob into the master bedroom where Ellie's parents normally stayed.

Rob was shocked to find that he couldn't move at all while being restrained by Elsa. Sure, he knew that Elsa was strong, but not this strong! It was as if the weight of humanity's sins was bearing down on him, locking him in place.

"What'd I say about resisting?" reprimanded Elsa while giving Rob an ominous look.

Not wanting to incur anymore of Elsa's wrath, Rob promptly stopped struggling. It was hotter to be held down anyways.

Yet despite his excitement, Rob still felt uneasy about all of this. There would be no going back from this point onwards, so he decided to vocalize his concerns now.

"Hey Elsa, maybe we shouldn't do this."

His thoughts drifted back to the incantation he was studying earlier. It claimed to meld the "love of the soul with the lust of the mind".

Inconceivably, Rob felt somewhat uncomfortable about copulating with the fusion of his girlfriend and her literal dog.

Elsa noticed the trepidation lurking within Rob and her expression softened. Leaning in close to his ear, she whispered, "It's okay, I'll be gentle."

With that she maneuvered her hands to remove Rob's trunks.

"Wait!" cried Rob. "What if the neighbors see?"

He gestured towards the bedroom window. For some reason, there were no curtains to speak of. Did Ellie's family not value their privacy?

"Don't worry about that," soothed Elsa.

Then, with great fluidity, she slid off Rob's trunks and tossed them onto the floor.

A gasp escaped Rob as he felt Elsa begin to caress his rigid manhood. Elsa, noting his reaction, did not relent. She ran her palm across the head of Rob's shaft, allowing the physical clues his body gave her to guide her hand's movements.

She noted how his body quivered as her hand explored every nook and cranny of his erection.

She scrutinized the beat of his heart as her hand reached different locations on his gushing arousal.

She studied his labored breaths as she slowly traversed and conquered his sensory labyrinth.

All Rob could do was clench down on the bed sheets as Elsa ruthlessly exploited every one of his phallus' weak spots that she had discovered.

"Stubborn are we?" teased Elsa. "I'll have to punish you for not being honest."

With that, she began to intensify her efforts. Her hand, having been lubricated by sweat and precum, ran seamlessly over Rob's pulsating member in what was now a well charted route for her fingers.

Nearing the point of release, Rob shifted his hips in an attempt to escape the inevitable. Elsa was wise to this though, and retained her grip on his cock. She grinned as she felt Rob swell in her hand. There was to be no escape.

"That's right," whispered Elsa lasciviously into Rob's ear, "let it all out for me~"

All Rob could do was moan incoherently as he was pushed beyond the brink.

Elsa trembled as she felt Rob throb fervently in her grasp before covering her hand in a healthy serving of his sticky semen. She could only imagine what it would've felt like if that massive cumshot had been released directly inside her deepest parts instead.

"That was a huge load," remarked Elsa adoringly.

She examined Rob's goopy love nectar as it oozed between her fingers and down her hand. It possessed a pungent, manly odor that quickly filled her nostrils, increasing her arousal tenfold. Enraptured by the scent of Rob's seed, Elsa longed to extract more thick and hot cum from his engorged manhood.

"Let's take a break," implored Rob, his face flushed from the exertions of a powerful orgasm.

In response to Rob, Elsa made a show out of licking his sperm off her hand, deliberately sucking on each of her fingers in a provocative manner.

Blood surged into Rob's phallus as he watched Elsa churn his baby batter in her mouth with her tongue like a cement mixer before swallowing it with an audible gulp.

"Still want to take a break Rob~?"

Having brought Rob back to full mast, Elsa climbed atop of him and methodically maneuvered herself into the sixty-nine position. She ensured that every curve of her voluptuous form made contact with Rob's bare skin as their sweaty bodies pressed and shifted against each other. Elsa's body was a potent weapon when it came to inciting a man's lust, and she exploited this fact to the fullest.

A few seconds passed as Elsa savored Rob's erection in all its veiny, musky, throbbing glory. She lusted for Rob to invade her with his virile manhood and flood her insides with his thick and creamy semen. For now though, she would satiate herself with a stomach full of his sperm instead. After all, you had to enjoy the appetizers first before you progressed to the main course.

"O-oh God," moaned Rob as he felt Elsa devour his girthy arousal.

His legs quivered uncontrollably as Elsa slathered his cock with a mixture of her sticky saliva and the precum that continually gushed out of his erection. He could feel Elsa's tongue caress his most sensitive spots, hell bent on coercing every last drop of cum into her eager gullet. All of this was compounded with the sensation of Elsa's hot breath rhythmically caressing the head of his shaft in her sauna-like mouth.

Not to be outdone, Rob untied Elsa's panties and began to explore the intricacies of her erogenous slit, his tireless tongue sliding into all of its most sensitive ridges and folds. Only when Elsa had become accustomed to the feeling of Rob's tongue on her vulva did Rob shift all of his efforts towards her clitoris, eliciting from her a sensual moan and forcing her to momentarily withdraw from giving him fellatio. Affirmed by this big reaction, Rob began to suck on the small bead of flesh.

Determined to get Rob back for making her moan, Elsa went down on Rob's shaft with even more zeal than before. His erection prodded the back of Elsa's mouth as she tried to force it down her greedy gullet. After several tries, Elsa was finally able to get it to slide down her throat, a lewd bulge appearing in its wake.

Inch after inch of Rob's manhood sheathed itself within Elsa's esophagus until Elsa's nose was pressing against the base of his shaft. It took every iota of willpower that Rob had to not blow his hot and steamy load immediately as Elsa's rippling throat-ussy massaged his pulsating member from every conceivable angle. Keenly aware of his proximity to an orgasm, Rob had to act quickly or else Elsa was going to make him cum first.

Thus, while doggedly resisting the urge to inseminate Elsa's throat-ussy, Rob gently nibbled on Elsa's clitoris, liberating from Elsa's depths her first orgasm of the night. Every muscle in Elsa's body tightened as she braced her mind and body for the euphoric feeling of release that was to come at any second.

Powerful contractions from Elsa's esophagus assailed Rob's cock as Elsa showered his face with her love juice. Rob was not finished with Elsa yet though, and her eyes widened in alarm as she felt Rob's slippery tongue breach her slit. Even though she had just came, Rob continued to writhe and worm his tongue deeper and deeper into Elsa, exposing her to brain to such a myriad of exotic sensations that she teetred on the brink of being overcome by erotic bliss.

Fortunately, or perhaps unfortunately for Elsa, Rob quickly had to cease giving her cunnilingus as he too found himself overcome by the ecstasy of release.

A mind-rattling orgasm enveloped Rob's brain as his eyes rolled back into his head and his tongue flopped uselessly out of his mouth. This was accompanied by a massive cumshot as a torrent of piping hot baby batter came surging out of Rob, much to the delight of Elsa who greedily gulped it all up. However, Elsa was still far from satisfied.

"Hey don't pass out on me now," quipped Elsa after unsheathing Rob's saliva-coated cock from the depths of her throat. Not one speck of Rob's seed was visible on it as it glistened dazzlingly in the sunlight that streamed in through the window.

"No more," implored Rob. "Just let me rest a bit."

Elsa took in the sight of Rob's disheveled hair, flushed complexion and pleading eyes. Her enhanced sense of hearing could detect Rob's delicate gasps for air as he struggled to steady his breathing and tame his frantic heartbeat. She wanted to let Rob rest. She really did. The thing is, she wanted to fuck his brains out even more.

Now that she thought about it, wasn't it unfair of Rob to ask for a break when his scent permeated the very air that surrounded her? How dare he claim to be exhausted while continuing to exude the titillating cocktail of smells that beckoned her to completely drain him of his cum! Elsa could smell the intoxicating aromas of Rob's semen, sweat, and distinct musk all at once, yet he selfishly expected her to go against her basest instincts of reproduction and sex!? Surely if Rob truly wanted to stop then he wouldn't smell so... enticing.

Fueled by her uncontrollable lust and reassured by her mental gymnastics, Elsa seated herself atop of Rob's lap in the cowgirl position. Her tail wagged with a fervor that indicated her eagerness to welcome Rob into her deepest parts.

"I'm going to fuck you until your dick breaks," Elsa informed Rob. "And I won't stop even if you beg me to."

Drool splattered from Elsa's panting maw onto Rob's sweaty chest as she grabbed Rob's flaccid member and pointed it towards her sopping wet entrance. Much to her annoyance though, Rob was not getting erect.

"I told you I can't get hard again that quickly," asserted Rob.

Exhaustion and annoyance were evident in his voice.

"Oh really?" remarked Elsa, her ears perking up as her mind birthed a new idea.

"W-wait," pleaded Rob as Elsa began to grind on him. "Stop! It's still sensitive!"

Elsa, completely ignoring Rob's pleas to stop, continued to rub herself along the full length of his shaft. A loud squelching sound could be heard as Elsa slathered Rob in a concoction consisting of his own precum mixed with her perverted secretions.

A grimacing Rob watched in dismay as Elsa slowly but surely roused his member back to life against his will. Having already ejaculated twice today, achieving an erection now proved to be a rather painful endeavor.

"There we go!" rejoiced Elsa after feeling Rob grow rigid under her.

Possessed by an overwhelming urge to mate, Elsa hefted her plump ass into the air with the intention of making Rob watch as his throbbing girth slowly entered and gouged out her breeding chamber.

"Hey pay attention," ordered Elsa before descending on Rob. "I'm swallowing you up~"

The head of Rob's shaft kissed the entrance to Elsa's love canal, causing Elsa to shudder in lustful anticipation for what was to happen next.

Neither Rob nor Elsa could refrain from moaning as Rob's cock, lubricated with cum, spit, and various bodily secretions, brutishly stretched apart Elsa's tight little hole.

"Y-you're so tight!" cried Rob, digging his fingers into Elsa's back and drawing blood.

Together they watched as inch after inch of Rob's cock slowly forced its way into Elsa. Moans poured out of Rob at an incessant rate as his shaft, being in a heightened state of sensitivity, radiated with pain and pleasure as it was squeezed mercilessly by Elsa's writhing insides. Then, with one more plunge from Elsa, Rob bottomed out.

"Ohhhh fuck YES~," Elsa half moaned half screamed.

All Elsa could do was bite down on her bottom lip as ecstasy overloaded her lust-addled brain. A moment passed as Elsa savored the feeling of Rob's manhood nestled within her deepest parts. Only when Elsa heard Rob let out a particularly carnal moan did she begin to move her hips.

Rob's cock repeatedly knocked on Elsa's cervix like a battering ram as Elsa bounced up and down on his hips as fast as she possibly could. Overcome by a feral haze, Elsa failed to stop herself as she reached out and grabbed Rob's defenseless throat. As Elsa tightened her grip on Rob's throat, she discovered that his manhood swelled in accordance to how hard she squeezed.

"You dirty fucking whore!" chastised Elsa. "You love it when I choke you, don't you!?"

In response to Elsa, Rob fruitlessly attempted to pry her hands off his throat as she repeatedly slammed herself against his hips. Soon Rob was becoming lightheaded as his brain received less and less oxygen with each passing second. Tears welled up in his eyes as he desperately gasped for what little amount of precious air he could suck into his throat. A guttural sputtering noise emanated from Rob's gullet as he lingered on the threshold between pain and pleasure. On the one hand, Rob feared for his life as he looked up to find Elsa gazing down upon him with a 1000-yard stare while slowly squeezing the life out of him. One the other hand, he couldn't help but find the prospect of being completely at Elsa's mercy incredibly arousing. It was a fine line, that's for sure.

Only when Elsa felt Rob swell inside of her, a harbinger of his coming orgasm, did she relinquish her grip on Rob's throat. A great fuzzy heat spread throughout Elsa's belly as Rob filled her breeding tube to the brim with his piping hot cum. Upon feeling herself get inseminated, Elsa pumped her hips even harder, causing Rob's semen to spill out of her overflowing orifice. A few sloppy plunges later, and Elsa let loose a primal howl as she too achieved a euphoric orgasm that electrified her senses.

Leaving Rob's deflated cock to languish in a pool of its own creation, Elsa used two of her fingers to spread open her stretched out entrance. With labored breaths she admired the stream of thick and creamy love nectar that came oozing out of her and onto the now thoroughly dirtied bed sheets. God, what a creampie! The thickness and the quantity of it was just spectacular! Rob had outdone himself with this one! Speaking of Rob...

"Oh shit!" exclaimed Elsa when she looked over at Rob.

The feeling of constriction still lingered in Rob's throat as he wiped his tears off his face.

"What the fuck Elsa?" demanded Rob between wheezing coughs.

"S-sorry about that Rob," apologized Elsa. "I may have gotten a little carried away."

"You think!?" snapped Rob as he massaged his bruised throat.

"But you know," remarked Elsa with a smirk as she leaned in close to Rob, "your cock seemed to love it when I had my hands wrapped around your cute little neck."

"W-what?" stammered Rob, completely blindsided by Elsa's teasing. "N-no way, I thought I was going to die!"

Seeing right through Rob's pathetic façade, Elsa extended her hand and firmly grasped Rob's throat before he could react. An involuntary shiver of delight ran down Rob's spine as he felt Elsa touch on his neck.

"Who's a good boy?" Elsa whispered lewdly into Rob's ear.

"I am. I'm a good boy."

The End
