“Oh MAN, I just can’t believe how that ended!” 

Sephanine’s gloating certainly knew no bounds. He kept repeating his complete surprise several times over, sporting a grin that stretched across his short, feline muzzle. The king cheetah was taking great pleasure in his Warhammer 40K victory against his friend, Ryuukin, and she knew he wasn’t going to stop gloating anytime soon.

“Hey, how about we wrap this up and go to bed? It’s getting late, you know.” It was already late in the evening, but Ryuukin had another thought in mind. Maybe getting ready to sleep would cut short Sephanine’s victory speech by a good ten minutes or so. The last thing the sleek, onyx-furred wolfess needed was her love gloating over his skills.

“Seriously,” Sephanine continued, almost ignoring his beloved’s suggestion, “how my succubus took down your Bloodthirster was a work of art!”

Ryuukin rolled her eyes and sighed to herself. The tirade was going to play out in full and there was nothing she could do to stop it. At least Sephanine got up at the same time and started walking towards the bedroom. The cheetah was an adorable sight, an absolute treasure of a boyfriend,, but he took his victories as seriously as a heart attack. 

To be fair, Ryuukin had an overwhelming amount of adoration, but as she held her tongue, she soon found her patience wearing thin. 

“Yeah, yeah. I’m sure I’ll see an artist’s rendering of your win in the Louvre someday, dear.”  It was a long enough day as it was, and all of the wolf’s love couldn’t hold back at least one quip. “Bed? Now? Please?”

“You’ll do better next time, I know it! You just need an affinity for your faction, like me! I mean, I’m all about the Dark Eldar! I don’t know how you’d fare with them, though.” 

With Sephanine being so wrapped up in his victory, he had barely noticed what was transpiring behind him. The gracious wolfess found him getting on her last nerve, especially with his casual ignoring. While strolling behind him down the hallway, he could barely hear her grumbling as her tail lashed about behind her. It tapped against the wall enthusiastically, dancing about as if she had just won the lottery, as gargantuan spikes started to arise from her sea of jet-black fur. They rose upwards from her tailbones just as two different sets of horns sprouted out along her forehead. One pair began right behind her lengthy canine ears, curling around from behind them and growing outward in front of her until they  jutted forward. She could easily see them in her peripheral vision, and she knew that, even with her elongated muzzle, she could easily show sweet affection with a kiss, or main someone quite terribly with equivalent ease.

The second pair of horns grew slowly from her forehead, rising towards the ceiling. They grew an impressive six inches, and were of a purplish hue that seemed otherworldly. All the while Sephanine get gloating on and on, not even hearing his love’s clothes begin to tear apart. The fabric couldn’t keep a hold on her form as it started to gain muscle mass all along her torso and legs. With the greater tone and definition came a surge in height as well, quickly taking her from being just the same height as Sephanine to being nearly as tall as the ceiling itself. 

“I don’t know,” Ryuukin murmured, “I think I could rile you up if I went all Dark Eldar and all. It just feels so…ME.”

“Really? What do you like most about…the…” 

Sephanine’s jaw hung wide open as he finally turned around to address Ryuukin. What he saw towering above him by a good two feet looked somewhat like her, still canine in many respects, but it was positively oozing in demonic power. As he stared dumbfounded at her powerful, naked body, he was awestruck by her bodybuilder-esque proportions, magical and physical power just emanating everywhere off of her. He could have sworn he heard leather rustling, but he didn’t get the chance to see her new wings unfurl behind her.

What he did receive, though, was quite a powerful kick from her right foot against his cream-colored chest. She lunged forward with her leg and followed him down the entire way until he hit the floor. Her powerful footpad was enough to keep him pinned with minimal effort, and she threateningly loomed overhead.

“Oh, if I had to guess,” Ryuukin replied, with each word ensconced with lust, “it might be something…carnal.”

Ryuukin’s normally azure eyes, which Sephanine was all too happy to stare at every day, took on a fiery color and glow. They shined so much he could barely see anything more than crimson light peering right back at him, as if peering through his very soul. He tried to squirm along the carpet at first to escape her grasp, but the second her razor-sharp nails clicked outwards, he knew better than the move. 

Still, even with his forced obedience, Ryuukin still took profound joy in slowly raking her foot claws along his shirt, easily rending it to shreds with a few light strokes. She exposed his golden and eggshell-hued fur, and took great care in fanning through it with her toes.

“What’s the matter, love? Finally all demon-ed out for the night?” Ryuukin sneered at him, baring her teeth at him with glee. Her elongated tongue traipsed around them as she let it danger heavily outside of her maw only to lick her chops. 

As much as he wanted to protest, the immense beast on top of him was menacing enough he wouldn’t dare. He laid there silently, save for the several large gulps he emitted as he thought about the possibilities.

“All quiet now? That’s a good boy. Perhaps you’ve earned this…” Ryuukin held her left hand aloft before balling it into a fist. It soon emitted a bright light just as powerful as her eyes, right before she slowly relaxed her grip and let something fall from her grasp. 

It was a lengthy leash, as black as the night sky, with a faint bloody glow about its form. At the very end of the flexible material was a collar that was nearly half-an-inch thick and heavy. It was as black as the rest of the leash, and from the way it dangled audibly off of the length of material there was no doubt that whoever wore it was not going to get it off again with any sort of ease, if ever.

“Still speechless? That’s fine, I like my playthings nice and quiet. At least until I want them to scream, of course.”

In a single motion she slid her foot off of Sephanine’s chest, retracted her claws, and kicked him softly. The cheetah flipped over onto his chest as easily as a flipped pancake, and even though his feline instincts had him lean back a bit, ready to spring forward into the bedroom and sprint to safety it was no use. Ryuukin’s speed was no match for him, and she pulled him upward by the scruff of his neck as she walked them both towards their bed.

“No use running, now. I can smell your arousal, anyway, so you’re not fooling me.” She was quite right, and what remained of Sephanine’s pants had been tenting, much to his astonishment, ever since he laid eyes on her enhanced form. “Now, either you’re going to be my slave or you’re going to be my pet, it’s that simple.”

A quick clasp was all she needed to adorn Sephanine with his new collar. Suddenly, iIn the blink of an eye she tossed him onto their oversized king bed, face-up, before she pounced atop him. Being in quite the dominant position, the wolf demoness hunched backwards as she knelt along her beloved’s torso, widening her legs and shifting about until she could get her pussy right on top of his face, letting him breathe in all of her scent.

“You’re going to satisfy me every way that I see fit, little kitten…or else.”

Her luscious scent filtered its way through Sephanine’s nose with ease. He had encountered it many times before, but tonight it was as if it was walloping him in all of his senses at once, not just his sense of smell. As much as some part of his mind still wanted him to slip out from under her and get away, the notion was simply out of his hands. The collar was as weighty as a millstone, and even if his love’s thunderous, powerful legs weren’t forcing him into the mattress on their own, the collar would be more than enough to weight him down and slow his escape.

By the time his tongue slipped along Ryuukin’s nethers, though, all thoughts of escape scampered out of his mind. Her taste was utterly transcendent, as enhanced and as seemingly corrupted as the rest of her body. Sephanine could barely wait past the first lick to go back for more, rolling the tip of his tongue against her petals from bottom to top. What started out slow slowly increased in both speed and fervor as the lanky feline saw all the more fit to delve deeper into that delicious offering, working his way upwards on every pass towards her clit. 

With each passing motion of his tongue he wanted to make sure to tease the very spots he knew gave his beau a rush of exhilaration. Even with her thighs held tight around his rounded ears he could still hear muffled sounds of appreciation from above. As thanks, Ryuukin’s slit was more than gracious to lavish her delicious nectar along his tongue and muzzle, soaking through his fur and staining him with her passion.

As the orgasms started to come more frequently, Sephanine stepped up his efforts by focusing near exclusively along the demoness’s clit. His appendage did its level best to swirl around the nub’s circumference, lavishing it with more attention than he had ever given it before. Each pass with the cheetah’s tongue eked out another shudder from the wolf above him until she spread her legs forward and sat fully along his face.

Once properly seated by forcing her captive feline’s head to tilt back to accommodate, she had locked him in the perfect position. No matter which way he moved his tongue he was bound to stimulate her clit or one of her several g-spots, and by thrusting her hips info that attentive maw of his she was assured a climax with every motion. She was more than happy to thoroughly soak her attentive little toy, and what wolf demon wouldn’t take such joy in making him breathe in nothing more than her seductive scent.

Sephanine wasn’t sure how long he had struggled beneath his girlfriend, but he did know that his eyes burned as she finally lifted herself up off of him. His jaw ached a bit from all of the lavish attention he gave, and his fur felt a slight chill as it grew exposed to the air in the bedroom. It took him a moment to realize it was because he was thoroughly drenched, from the top of his head all the way down to his chest, in Ryuukin’s cum. Despite all that, though, the heat between her legs was still just as ferocious as ever, lapping at his face as she stood up on the bed.

“Well,” she mused, right before she bent down to hoist the cheetah in front of her, “I guess that will have to do for a start.”

“A…a start?” Sephanine was dumbfounded. He had lost count of all of the orgasms she had had in the interim, but it should have been more than enough to sate her usual self for a week.

“Shut your eyes and mouth, dear, unless you want to see how angry I can be when I’m unsatisfied.” She slightly hissed as she let out the not-so-veiled threat, and Sephanine knew better than to raise her ire any further. His eyes slammed shut and he nodded in silent obedience, although any sense of fear he may have had was undercut by the emerging blush in his cheeks.

Ryuukin, pleased at the sight, decided to magically lengthen the leash by a few additional feet. Working quickly and walking around his body, she threaded and looped the leathery material all about his body. It took a few minutes worth of work, but she guided Sephanine’s shuddering arms and legs as she manipulated them, making sure that everything was set up properly. By the end, most of his spots were obscured by a wealth of onyx leather wrapped tightly along his fur,  right before she stuffed a small ball gag into his muzzle and clamped it shut with the very end of the leash.

The cheetah, finally fearing what she would do next, started to squirm in place. Not being one to take any sort of disobedience, the wolfess laughed loudly to herself as she took her prize in her arms and shoved him up towards the ceiling, back-first. His tail and spine struck first with a gigantic crash that reverberated throughout the rest of the apartment, the shock of which caused the feline to whine vivdly in surprise. All he knew was that he was feeling the strength of the binding leash around him increasing almost two-fold, right before he felt the tremendous pressure of Ryuukin’s paws on his chest and legs fade away.

It was only then that he realized that, somewhere along the entire process, his precious canine removed the rest of his clothes. He didn’t understand how much of his body was free from its leather adornments until he felt an intense heated breath right across his groin. His manhood, already at a crossroads about whether to be turned on by all of this or freaked out into impotence, clearly favored the former as he became tumescent. His cock dangled heavily downward, partly due to gravity, the rest to immense arousal. The rest of his body, unbeknownst to him, dangled a few inches off of the ceiling above their bed, legs tied together, arms affixed to his sides, and wiry tail free to dangle and thrash about as much as his cock.

“You’re pretty good as a cheetah, but I don’t think you have what it takes to sate me just yet.” Ryuukin stared upward at the sight, right before she ran her index finger along the crown of Sephanine’s dick. Her soft fingerpad slipped right underneath the rim of his head, and thanks to his slowly-flowing precum she was more than pleased to tease his pole. “Hope you don’t being my cow for a while. Don’t think for a moment that I’m going to be treating you as vigorously as you did with me, though.”

Before he knew it, Sephanine realized that the wolfess was true to her word. Her enhanced body also meant enlarged hands. With her grip strength immensely increased, she had no problem gripping along the entirety of his junk and working it at a feverish pace. Despite his usual ability to hold out, it was barely a minute before he could feel the typical urges come to the fore, his balls churning as they bobbled along in her grip, sending so much fluid upward he knew that he was going to make a mess within a matter of seconds.

Just as he was about ready to let his love fly, all of the intense pressure along his family jewels slipped away to nothing. His body was left entirely alone, swinging softly from the ceiling, as he listened to some coy laughter from down below.

“What’s the matter, love? Were you close to something?”

Ryuukin let him dangle from the ceiling for a few minutes more, letting the room ring with Sephanine’s frantic little moans, begging for relief.

“Oh, I think I get it. No, no, all of that belongs to me, you understand. You’re not nearly done yet, you know.” She snickered as she started to bat at his head once more, taking great delight in how it throbbed with an intensity that would make a hummingbird’s wings seem slow by comparison. “I’m not going to let you spill a drop until I say otherwise, so whine all you want.”

She was absolutely true to her word. For the better part of two hours she worked over her boyfriend like there was no tomorrow. As soon as she started to lay her hands on his privates he was ready to cum harder than he ever had in his life. The wolfess had to keep giving her wrapped-up treasure longer rest periods to accommodate, but it was all for the best. Right hand, left hand, both together, her seductive mouth, everything she offered his cock accepted with glee. The amount of pleasure she was able to work out of those several inches of thick feline dick was as boisterous as a fireworks display, to the point where Sephanine was doing his level best to hold back his urge to shoot his cream all over the bedroom just so he could have a few extra seconds of being manipulated.

By the time she wrapped up, Sephanine was at his absolute limits. He had never been edged so furiously in his life, and at his last count he was at the 80th edge. Maybe 92nd. All he knew was that his bounty was almost at the point of no return, and the beast below him made him ride that wave for minutes on end with dirty talk and further stimulation. He was so lost in the immense amount of pressure within his hefty cheetah sack that he barely noticed his leash letting up on its grip all around him. Ryuukin laid him down gently on the bed below, letting his head rest on their pillows as she hankered down on knees once more, holding herself slightly aloft off of the kitty’s hips.

“You held out a lot longer than I first thought, my spotted slut. Now, let’s see how long you can really last!”

No sooner than had she finished her sentence, Ryuukin quickly hoisted her backside downward until she rode Sephanine. With all of the constant attention from earlier, she was still slick enough between her legs that her pussy eagerly wolfed down the majority of her boytoy’s cock, gripping it with all of her might. Her walls were as smooth as silk to the cheetah, and after all of the attention he received he wanted to hold onto his sensational edge for as long as possible. He could have easily let his load come fast and furiously, to get it all over with, but he wanted more.

He had to get deeper inside that welcoming snatch. He wouldn’t rest until that tight grip around his shaft was sated, until his love’s body and his were shuddering in time with one another, sharing an immense orgasm that would be sure to break most of the springs on their mattress.

Sephanine rocked his hips along in concert with Ryuukin’s own motions. Every time the demonic wolf would lift off of his erection, he would slip his hips as far back into the mattress as it would accommodate, just to let that moment of impact when Ryuukin slammed right back down on his hips to have all the more impact for them both. Each thundering rush of her immense body made sure that he fully hilted her with each pass, his overloaded and bloated balls bobbing wildly between her legs. His precum production was heightened beyond belief from all of the milking attempts, with his tip eagerly gushing out steady spurts of nectar so rich that the canine above would have mistaken them for orgasms. Ryuukin, however, knew what to expect after all that work, and she bent forward a bit to let her pillowy breasts dangle right along Sephanine’s muzzle, batting him around the side of his head as she moaned the loudest she had since transforming.

“Come on, Seph, fuck me like the wild animal you are!! Show me how much my plaything can cum!!” Ryuukin screamed at the top of her lungs, finally growing close to that major climax she had been hoping for since the start. Sephanine’s head rubbed all along her velvety walls, approaching the back of her love tunnel as the heat within kept mounting. Just as he thought he was at his limit, he could feel both of Ryuukin’s powerful arms slip underneath his body right before he felt his upper half be smothered in her inky fur. 

Deep within her body, Sephanine could feel his cock absolutely drowning in a tidal wave of orgasmic bliss. It was if all of his beloved’s heat was stored within that fluid, and as its volcanic warmth enveloped the entirety of his length he couldn’t hold back any longer. His voice was lost between the ball gag and Ryuukin’s tits, whining as he felt powerful explosions shoot through his cock at a steady pace.

Several minutes passed as their orgasms finally started to die down. Everything below their hips was an absolute mess, with their fur so drenched with their shared fluids it matted along their legs. In all of their excitement Ryuukin was a bit surprised to find herself laying on top of her cheetah, weighing him down into the mattress.

“Well,” Ryuukin chimed, sounding quite a bit happier than earlier, “I guess I’ll keep you as my pet after all. Good job, you stallion of a cheetah. Um…Seph?”

The wolfess stared down at her beloved feline, only to find his crimson eyes rolled upwards in his head, his mouth agape in a grin as wide as she had ever seen. It was all too much for him, and as his tongue lolled about near the corner of his mouth it became obvious that he had passed out from the excitement of it all. 

Knowing full well how hard he had worked, she gleefully propped his jaw shut and snuggled into his side. A post-festivity shower was necessary, and she was dying to haul Sephanine’s spotty hide into the bathroom with her to keep the action going. Still, she had to admit to herself that he deserved the rest. 

Besides, tomorrow was another day, and she was still going to look like this for a while to come. May as well remind him about her own sort of “affinity” towards his preferred faction tomorrow. There was little doubt he was going to agree that Ryuukin played the role far better than he, after all.

Unless, of course, Sephanine wanted to “argue” about the point just a bit more. The demoness in Ryuukin adored it when he wanted to be quite...difficult.
