When Trixie summoned up infernal aid to help with a certain spell, she got more than she expected!

Trixie just needed pointers on a naughty little spell she was having trouble with--so naturally she summoned a succubus to help out. But Trixie's summoning know-how wasn't exactly up to snuff, and what she called up was less pony succubus and more furry hellhound named Loona.
Not that she's giving up on getting some help with that spell, though.

Contains futa and furries!

A crossover with Helluva Boss and an offering for Dirty Little Secret's Furry Foray Festival.

The Summoning

The occult symbols were chalked upon the floor, the candles of unholy composition were lit, and the arcane phrases of forbidden import were impressed upon Trixie's mind. I hope this is worth it, she thought as she pricked the coronet band of her hoof with a silver knife and let a single drop of unicorn blood fall at the center of the summoning circle.

She stepped back and took a deep breath, once more glancing around the hall of the abandoned old keep she'd decided would serve her purpose. Nopony had been here in a long time, so she needn't worry about interruptions.

Get on with it, she thought, and began chanting the invocation. “O agents of the nether realms, I call upon thee,” she announced, then lapsed into the phrases of a hellish language unsuited for pony throats. The sound echoed eerily through the great hall, the words grating at her throat, and it seemed to her that the shadows grew in the corners, hungrily lapping at the torchlight.

But Trixie was focused on her task, disregarding the gathering darkness and the sudden stench of brimstone that filled the air. She wrapped her tongue around the alien syllables of the summoning spell. Was it working? A rush of excitement and satisfaction passed through her as she finished the closing line and saw red-tinged smoke billowing in the summoning circle.

A moment later the thick cloud of smoke burst apart with a whoof. There, revealed, was the object of the summoning, the being Trixie sought. There at the center of the circle was... not what Trixie had expected. But... but then again, she had never seen a succubus before, so she couldn't claim to know what she had expected, right?

The creature in the summoning circle was a furry, long-limbed beast, white with a dark charcoal patch across her back and shoulders. She had a thick mane and a fluffy tail that was even thicker. Her muzzle was long and canine, her lips parted to reveal sharp teeth, and her half-lidded eyes were a startling red.

She was sitting on her rump, one foreleg planted between her thighs while the other caressed teats that was placed weirdly high on her chest. Trixie's cheeks grew hot at the display, though logically wasn't it only natural for a succubus to amuse herself thus?

The succubus' eyes suddenly widened as she took in her surroundings. She leapt to her hind legs, rearing over Trixie, snatching her foreleg from between her thighs and spattering a few drops of liquid to the floor while her other forleg crossed over her teats as if to hide them “What the fuck?!” she yelped. “Haven't you ever heard of alone time?!”

As Trixie stared at the succubus standing perfectly balanced on its hind legs, a sudden realization hit her. By Celestia's pink pearl, I've messed up! This isn't a pony succubus, this is a diamond dog succubus! Suddenly the oddness of the creature's anatomy made sense. Trixie's mind raced, going over every detail of the summoning spell. Had she transposed a syllable? Surely not her! Were the lines of the circle accurate? She'd checked them thrice! What about the candles? Maybe they weren't the right kind of wax? Yes, it wasn't her mistake; it must be a problem with the candles! She thought they'd smelled funny from the start! But never mind that, she had a diamond dog succubus on her hooves and what was she going to do with that?

“This is not a problem,” she muttered, “Trixie can recover from this, easy! A succubus is a succubus in the end, it really doesn't matter which type!”

The succubus was staring around the hall, taking in her displacement from the comforts of the infernal realms, no doubt. Her gaze settled on Trixie. “What. The. FUCK!” she said. She looked down at the chalk lines on the floor. “Is this a summoning? You summoned me? Why the FUCK would you summon me?!”

“Ahem,” Trixie said, rearing on her own hind hooves for dramatic effect. This put her just above eye level with the succubus' teats (no, wait, diamond dogs called them breasts, right?), which would have to be imposing enough. “I, the Great and Powerful Trixie, have summoned you to do my bidding, infernal creature!”

“Uh huh.” The succubus stared at her. “You're a horse. Are you telling me I was summoned by a horse?”

Trixie frowned. “Did you say 'whorse?' Trixie hardly thinks a succubus should be casting aspersions!” She wrinkled her nose. “Especially when you smell like a dog to boot.”

The creature made an obscure gesture at her with the central claw (or was it called a finger?) of it's paw (or was it a hand...?) “You're not a horse?” it said.

“Trixie is not any kind of whorse. Trixie is a great and powerful unicorn pony! One so skilled as to summon a succubus like you into this place!” She dropped back to all fours, tossed her head and brushed her chest with one hoof to imply it had been scarcely an effort. And that she'd intended to draw a diamond dog succubus from the nether realms rather than a pony one. It hadn't actually occurred to her that there were other kinds of succubi, which she had to admit was a bit parochial of her.

The creature sat down, hugging her legs in front of herself. The big paws of her hind legs rested on the edge of the chalk outlines of the summoning circle. “Well, Trixie isn't such a great or powerful summoner, because Loona is a hellhound, not a succubus.”

Trixie dropped back to all fours and took a step back in startlement. “Luna? What does Luna have to do with this?”

The succubus... the not-succubus (seriously? Trixie could not have bungled the summoning that badly! Maybe it was just toying with her.) gave her an irritated look. “That's my name. Loona.”

Wh-wh-wh-what?! Was this Princess Luna? In some sort of diamond dog disguise for some reason? What was going on? “Princess Luna?” Trixie sputtered. This wasn't possible. She'd summoned a succubus, not a princess! Although both “succubus” and “princess” ended in “s” so maybe the magic got confused?

“'Princess?' Ugh, you sound like my dad.”

Dad? Princess Luna had a dad? Trixie felt like her brain was spinning. Didn't it make sense for Princess Luna to have a dad? But she'd always assumed Princess Luna was eternal, like Princess Celestia. Eternal beings didn't need dads, they just sort of existed. Wait, did this mean Princess Celestia had a dad as well? They were sisters after all.

“Pardon me, Princess Luna, I'm having an ontological crisis right now.”

Princess Luna growled. (Why is she taking the form of a diamond dog, though?!) “Stop calling me princess, it's creeping me out. The name is just Loona. L-O-O-N-A, Loona.”

L-O-O-N-A. Ell-oh-oh-enn-ay. Loona. Looooooooona. Loona.

A rush of relief swept through Trixie. “OH!” Of course this wasn't Princess Luna in some diamond dog disguise for unknown reasons. That would be silly! “Oh... ahahah, Trixie understood that. Naturally you spell it differently. Trixie could tell.”

The creature... Loona gave her a funny look. “Yeah, okay, you got any clothes or something for me to wear? I'm feeling kind of exposed. Or tell me what I'm doing here? Or just fuck off and send me back home?”

“Clothes?” Trixie was not performing and given the intimate nature of her task had not thought to wear her wizard cape and hat. “Trixie did not bring any clothes. Trixie did see the need for any. Ponies don't normally wear clothes in any case.”

“Well isn't that great. I've been kidnapped by a nudist.” Loona looked around. “Did you say 'ponies?' As in plural? There are more of you around?”

“Trixie needed no assistance; we are alone.”

“But, like, there's a whole town of you?”

“Town? Equestria...” Trixie paused and glared at Loona's stifled snort at the word “Equestria.” “Equestria is a grand nation full of whole cities of ponies.”

“Shit, you should have summoned Blitzo. He'd be in ecstasy.” Loona seemed to relax a little. “He's not a succubus either, though. Still might fuck you, I guess, not that I want to think about him fucking anyone. Ick.”

Trixie felt her face grow hot. “I wasn't... I didn't... Trixie did not summon a succubus for the purpose of erotic dalliance!”

“Really? It's about all they're good for.”

“Trixie had perfectly legitimate reasons to summon a succubus,” she insisted.

A half-smile appeared on Loona's long snout. “Well shit, I wanna hear this.”

Trixie hesitated a moment, uncertain if she really wanted to share such matters with the creature. Then again, it came from another realm entirely, so it wasn't as if it would be blabbing to anypony else.

“You see, Trixie has a marefriend—”

Loona stifled a giggle. “Marefriend. Okay.”

Trixie stomped a hoof. “I don't see what's so funny.”

“No, no, go on,” Loona said. “Tell me about this marefriend.”

“Well... Trixie likes mares...”

“Yeah, I figured.”

“...but Starlight's tastes run to both mares and stallions.”

“Uh-huh.”

“And Trixie was thinking that it would be a nice surprise to let Starlight enjoy the, ah, male appendage. Via magics which would temporarily affix such an organ to one's body.”

Loona stared at her. “You want the dick spell.”

Trixie's cheeks flushed hotly once more. “I want the dick spell.”

“You don't know the dick spell?”

Trixie balked. What was the demonic diamond dog implying? “You do know the dick spell?”

Loona shrugged. “I mean, when bitches hit puberty it tends to get passed around a lot between friends. Everyone wants to know what it's like for the boys, right?”

“Ummm, Trixie supposes that sort of curiosity is only natural.”

“You don't do that?”

Trixie cleared her throat. “Only a few unicorns are blessed with the sort of magical talent Trixie possesses, and can work more than a handful of spells unrelated to their cutie marks. So no, we don't do that.”

“Cutie whats? No, nevermind. So you horses don't have the dick spell, then.”

“Ponies. And it isn't that we don't have it... it's just not usable by most, or well-known. Trixie spent a bucketfull of bits to get a copy of the Kamare Splootra. Trixie knows the spell, it's just... some of the nuances are proving difficult to master.”

Loona gave her an appraising look. “Are you a shit magician, Trixie?”

“What?! How dare you! The Great and Powerful Trixie is one of the most awesome sorceresses in all the land!” She glared at Loona, but then the hard line of her mouth softened. “Starlight is... much more practiced, I suppose, and Twilight Sparkle, damn her. And the princesses, but alicorns don't count.”

“Okay, whatever that's about.” Loona said. “Do you want me to go over the dick spell with you?”

Trixie tried to shrug in a casual manner. “Well, Trixie wouldn't mind seeing another's approach to it.”

“All right then.” Loona crawled out of the summoning circle to where Trixie had left the chalk on the floor.

Trixie took a step back. “Th-th-th-the seal...” she said. How had Loona broken free of the circle? And so easily!

Loona glanced back at the elaborately chalked circle. “Yeah, you probably want to practice drawing that more.” She gestured to the section governing borders restraints. “That bit is growling at me, but it doesn't really lock me down like it should.”

“Well, Trixie must have rushed drawing it. Normally—”

“Uh huh.” Loona was sketching out magical notations on the stone floor. They weren't entirely readable, but parts of them echoed written spellcraft as Trixie understood it enough for her to grasp the gist. She supposed it was only natural that the manner of writing down magic would have developed differently in whatever infernal realm hosted Loona.

Soon she was deep in conversation, figuring out how to properly read the marks and explaining Equestria's own spell notation. It was almost like discussing magic with another pony, except this pony looked like a diamond dog, except less lumpy, except for those weirdly appealing large teat-lumps on her chest.

As they pored over their chalk scribbles on the floor, Trixie leaned in and pushed her muzzle between the soft mounds on Loona's chest. They were so warm and pillowy, and feeling them slide against her nostrils sent a surprising thrill through her body.

But Loona jerked back at her touch. “What the fuck, Trixie?”

Trixie gave her an innocent look. “What?”

“First off, you nearly poked my eye out with that horn of yours. Second, who gave you permission to get handsy with my tits?”

“You mean hoofsy, right? Trixie was just curious about them. They're so much bigger than pony teats.” She squatted on her haunches and balanced upright, showing her own modest swellings to Loona.

“You don't have to show... ugh. Just mind your own business.”

“Hmph,” Trixie snorted. “Well fine.”

“You don't just shove your nose in someone's chest.”

“Trixie was paying you the compliment of showing some interest in your anatomy.”

“Yeah, don't do it again.”

“No need to worry, you smell like dog anyway.” Which was the truth, but Trixie had been being very polite about it.

Loona growled. Trixie looked away, turning her attention back to the chalk notes outlining the dick spell.

“Well I suppose I should be happy I'm considered busty in this world,” Loona grumbled. “So do you understand how it works now? You ready to try it out so I can go home?”

“Of course Trixie is ready! Who do you think you are dealing with?” She quickly skimmed over the notes once more. While parts of the spell resembled what she'd seen in the Kamare Splootra, other parts were very different, and she still wasn't quite sure of the logic of how it all fit together. But she wasn't about to admit to uncertainty; that wasn't the stuff a great and powerful showmare was made of!

“Yeah, okay, let's see your horse magic, then.”

“Unicorn magic. Ahem. Right. I'll just... get on with it then.”

She smiled brightly, gathering the magic in her horn to spin into the shape of the spell. You can do this! Easy as teacups! The magic bent to her will as she pressed it into the right configuration. There! No, that's not quite it, bring it around... yes, that's how it's supposed to go. She focused, and felt the magic tremble unsteadily. How exactly did it go? A bead of sweat formed on her brow, but then she gave the magic a shove and felt the spell snap into form. It released and poured down her body, arcane energy sweeping across her nerves and prickling her hide.

At first she felt unaffected. Had it failed after all? She thought she'd done it right, the feeling at the end had been the feel of a well executed sorcery. But then she became aware of a sensation of tightness in her groin, nestled between her teats.

Yes! Starlight was going to be so thrilled! A lovely pony cock with a sweeping flare and a fat medial ridge, just right to ravage a horny lover's pussy! She could sense it throbbing between her thighs.

Trixie looked down, eager to appreciate the fruit of her spell.

And then shrieked at what her eyes found. “WHAT IS THIS?!” She reared up on her hind legs and staggered back, as if she could walk away from the thing that stood out from her groin.

It was all wrong, a shockingly bright red shaft, pointed rather than flared. It had no medial ridge, but at the base of it was a weird, rounded thickness, which she almost thought was supposed to be her testicles, except no, she could see her testicles, thankfully ponylike and appropriately settled between her thighs just below the rather furry sheath.

“This is wrong!” She glared accusingly at Loona.

But Loona was unperturbed. “What are you talking about?” she said. She stared at Trixie's shaft. “That turned out really well.”

“That's not a pony cock!”

“...Really well.” Loona's gaze was fixed on the organ. She padded forward like a shark homing in on its prey. “That's the dick spell, Trixie. You did great.”

Trixie stumbled back. Her hind legs gave out and her rump slammed to the floor, the alien dick jutting shamelessly forward. “That... thing... is a dog dick!”

“That's a hellhound dick. One to be proud of. You may not be a shit magician after all, Trixie.”

“It's supposed to be a pony dick!”

“Oh, this is much better.” Loona closed in on Trixie's cock, her nose hovering over it as she sniffed and snuffled at it.

Trixie was suddenly hyper aware of her cock, the sensation of its throbbing eagerness, the pleasurable strain of it's hardness, not so different from her clitoris when swollen in the throes of passion.

The primal feeling of need.

It was a bizarre experience, not merely the sensation of an appendage where there had been nothing before, but the power with which it seized her attention, demanding more from her while she was still struggling to process the existence of this hefty slab of meat as a part of her. She wanted to do... something? Touch it? Stroke it? That's what stallions did with theirs, right?

As she stared down at it, she saw a silvery bead of liquid appear at the hole in the tip. It grew as she watched, until it suddenly began to roll down the pulsing shaft. That... that was precome, right? A stallion's natural sex lube. She was producing precome. And that... that meant she could produce semen too, right? She could ejaculate like a stallion. That was the whole point of learning this spell, after all, wasn't it? What did it feel like? Was it like squirting as a mare, or somehow different? She... she could find out! She could discover that for herself....

A shiver of excitement ran down her spine at the thought.

Then Loona gave her a lick. Her long thin tongue slid up the shaft, leaving a slick trail of saliva and catching up the dripping pre. The tongue plastered itself to Trixie's new flesh like a wet sheet in a windstorm.

“Hghwmpphhllghh!” Trixie gasped. Pleasure swept through her body in a crashing wave. Her almost forgotten pussy quivered and clenched, spilling her own female juices down her rump in a warm trickle.

“Do that again,” she whispered.

Loona licked once more, and Trixie moaned as the sweet delight shuddered through her cock. Then the hellhound drew back and tore her gaze from the cock, looking up at Trixie with a hungry grin. “You want to try it out, don't you,” she said.

Trixie swallowed thickly and nodded.

Loona brought her fingers up to the knot-like swelling at the base of Trixie's cock and traced them caressingly along the flesh, sending fresh shivers of wanting up Trixie's spine. “You picked a shitty moment to interrupt me when you dragged me here, you know.”

“Y... you were clopping,” Trixie said in a meek tone. “Trixie thought so. Trixie is sorry—”

“I was jacking off! I was close, too. And the next thing I knew I was here. I didn't even have a chance to grab my phone!” Loona set her hands on Trixie's chest and pushed her onto her back. The heavy cock bounced against Trixie's belly, and Loona crawled up her and straddled her barrel.

Her crotch pressed against Trixie's cock, her weight bearing down on the shaft in a delicious teasing way that only made it harder. Trixie whimpered softly. She could feel the warm lips of Loona's vulva against her shaft, and the growing slickness as the hellhound's own arousal drizzled along her flesh.

“You going to make it up to me?” Loona said. She rocked her hips, sliding herself along Trixie's cock. The new sensations left Trixie shaking with excitement, and she ground up into Loona with an instinctual need she didn't know she had.

“Yes!” Trixie cried out. “Please let me make it up to you!”

“You think you know how to use that thing? You think you can satisfy a hellhound bitch?” The rolling strokes of Loona's hips were a maddening siren call of delight, every slick motion sending tormenting thrills that only hinted at the full extent of pleasure this cock could provide.

“Trixie can!” Trixie yelped. “Let Trixie show you!”

“I thought you said I smelled like a dog, though.”

“Trixie... Trixie likes it!” Desperation was caroming through her body like billiard balls in a high stakes game, and she was willing to say anything to satisfy the need in her cock... but at the same time, it was true. Loona's scent had become seductive, a unique aroma calling out to her, now laced with electrifying traces of pussy musk soaking into her cock. In fact, she'd started liking the smell somewhere around when she'd cast the spell. Had the spell done more than just give her a hellhound cock? Had it also altered her perceptions to suit that cock's nature?

Trixie immediately discarded the Twilight Sparkle-esque analysis. All she really cared about now was discovering what new realms of pleasure her cock would introduce her to.

“All right then,” Loona said. “You better be better at fucking than magic, though.”

“Trixie is excellent at booo-ho-hoooth!”

Before Trixie could finish speaking, Loona had reached down with one hand, grasped Trixie's cock with the strange appendage (sending a thrilling jolt through Trixie's loins) and guided the tip to the lips of her pussy.

Then she thrust down.

Trixie saw stars as her cock slid into Loona's slick pussy. The surge of pleasure erupted through her, and her whole body tensed up as she was overloaded with sensation. The sleek walls surrounded her cock, hot and wet, stimulating every nerve all at once. This was what her cock craved, this was what it so desperately needed!

Loona let her hips sink until the thick knot was shoving at her. She held herself still for a moment, with a half smile on her face as she watched Trixie tremble beneath her, the pony's eyes wide but unseeing.

Just as Trixie started to come back to herself from the shocking rush of sensation, Loona began to ride her, thrusting hips up and down and bringing a whole new intensity to the experience. Trixie gasped, the dizzying feeling crashing through her. The slide of Loona's pussy around her cock was a constant electric burst of pleasure. It was so luscious and warm around her shaft... not unlike the warm wetness she felt around her tongue when she ate out Starlight, only it was like her tongue had all the sensitivity of her clitoris and felt like it was as thick and hard as her foreleg.

“Cocks are amazing,” Trixie whispered.

Loona snorted. She started to switch up the rhythm of her hips, sometimes going with agonizing slowness and satisfying, deep strokes before shifting to shallow but quick thrusts that took Trixie's breath away. Trixie could feel trickles of Loona's wetness spill down her shaft, and at times the silken flesh within Loona's pussy trembled against her cock.

It was heavenly. New urges awakened in Trixie, and she started meeting Loona's thrusts, straining up into them to bury her cock deeper.

“That's more like it,” Loona said. She took hold of one of Trixie's front hooves and brought it up to her chest, rubbing it against her teats. Trixie got the idea, and began caressing and squeezing at the soft flesh, teasing at the hard nipples. Somehow there was something intensely erotic about touching them, perhaps more spillover from the spell, but Trixie hardly cared. Loona leaned her head back with her eyes half-lidded, making soft noises of appreciation.

Trixie heard her own pants and groans, surprising herself with the sounds that escaped her. The wonderful sensations in her cock kept her floating in a haze of sweet delight, but she found it was beginning to throb in Loona with a building urgency. Loona dropped one hand down to her crotch and started running her fingers along Trixie's knot, rubbing the sex juices dripping from her pussy into the hard flesh. It made Trixie tremble, her need redoubling. She felt sweat begin to bead on her forehead, and a hard urge to thrust harder into Loona's ravenous pussy seized her. She began snorting and shoving her hips up, bursts of ecstasy shooting through her thighs.

And then, without any warning, Loona suddenly stood up. Trixie's cock pulled out of her with and obscene shlorkk! and slapped against Trixie's belly, and a thick string of juices momentarily kept cock connected with pussy until it snapped and spattered down Loona's thighs. Even though the sweet intensity of pleasure suddenly cut off, Trixie still felt it echoing though her haunches.

Loona stood on shaky legs, panting heavily as she looked at Trixie. Her bushy tail was wagging and a hungry whimper escaped her throat.

“Why did you stop,” Trixie said, hearing the whine in her voice but unable to stop it. “I didn't cum yet, did I?” Had she? She didn't think so, but this was her first time having a cock.

Loona bit her lip, gaze fixed on the shining wet shaft between Trixie's thighs. It twitched, and a shiver twisted through her body. Her face was flushed with excitement, the blush managing to pierce the white fur of her cheeks.

“Wanna... wanna do it...” she stared at Trixie, then suddenly giggled. “Horsey style!”

She dropped to all fours and turned away, so that she could wag her rump at Trixie. Her pussy lips were engorged and dripping with wetness. She looked back over her shoulder. “Get up and mount me properly! Fuck me hard as you can!”

Trixie got shakily to her hooves. She stepped behind Loona, admiring her stance, hind legs parted and tail up like a horny mare. She dipped her nose to the fragrant musk of Loona's pussy, so different from Starlight's yet so incredibly enticing, and slid her tongue up. Her cock gave an eager kick beneath her belly.

Loona had no patience for unicorn tongue. “Cock!” she growled.

Trixie's cock agreed with the sentiment, and she felt a hot rush of need sweep through her body. Her legs trembled with a powerful urge to bury her cock in that slavering hole, and she was caught by surprise as her haunches flexed and drove her shaft forward all on their own. The thickness was a steaming mass between her thighs, still dripping with Loona's juices, filled with yearning to return to the paradise of the hellhound's pussy.

Trixie reared up, grabbing Loona's hips awkwardly with her front legs and shoving herself forward. This is what it's like for a stallion to mount a mare, she thought somewhere in the back of her mind. At the front of her mind was only the pulsing desperation of her cock and the eagerness to feel it once more inside Loona's pussy.

She felt her cock bump up against something, and drove her hips forward. The shaft slipped down, rubbing along the fur of Loona's belly. It kicked and squirted a thread of pre across the fur. Trixie grunted in frustration at having missed the mark, but as she drew back she felt Loona's hand take hold of the shaft and guide it.

Trixie thrust forward once more, and this time she felt her cock sink into the soaking wet walls of Loona's pussy. A hot rush of ecstasy shot through her body and she shoved forward, sliding deep. The slick flesh quivered around her and then squeezed, imprinting itself onto Trixie's cock.

“That's right,” Loona breathed. Her hips rocked back to meet Trixie.

The sensations were heavenly. Again and again she pushed into the hellhound, her hips at the mercy of her cock's demands. Her body craved the rush of pleasure each thrust provided, and her cock shuddered and drizzled steady streams of pre, though Loona's juices were already so profuse that they constantly leaked out and spattered Trixie's thighs.

Trixie's flanks heaved as she panted. Her muzzle lay against Loona's neck, the soft fur tickling at her lips. She thrust steadily in a lustful euphoria. As her hips moved, Loona's pussy would suddenly spasm around her and she would gasp at the sensation. Loona too was panting and growling, her arousal clearly as intense as Trixie's own.

“Go harder!” Loona snarled. “Fuck like you mean it!”

Trixie gave a bestial bray, slamming her hips against Loona's rump. She hadn't exactly been holding back, but she knew what the hellhound meant. The tension in her cock was becoming unbearable, the instincts it roused in her calling her to shove deeper, ever deeper. Her pleasure was surging through her, but she needed more. The thick knot at the base rammed against Loona's quivering lips, soaked with the spatters of Loona's juices. Each time it met the hot flesh an electric jolt raced through Trixie. It all felt so good, but it would feel even better if she could press that knot all the way in, and bury every bit of her cock in that luscious pussy.

She ground her hips at Loona, feeling the pussy lips stretch around the knot. She was shaking, barely able to contain the building pressure in her cock. She jerked back, the feel of her hard meat sliding against the walls of Loona's pussy sending a ribbon of raw ecstasy shooting through her. Then she slammed forward again, striving to probe even deeper. The knot ground halfway into Loona's pussy, the sweet flesh embracing it in a hot kiss. The pleasure was boiling up inside her, an irresistible pressure fast reaching a breaking point. She was going to cum, she realized. This was what it was like for a stallion to cum.

She had time to pull back in one last thrust, then slam forward with all her might. Her knot battered into Loona's pussy, forcing it wide, and this time it plunged all the way in. Trixie felt Loona's pussy lips slip past the widest part, and then clench down in a reactive spasm, clutching at the narrower base of her cock.

Ecstasy exploded from every nerve. Trixie's cock kicked within the welcoming folds of Loona's pussy and then she felt herself spew the first spurt of cum. She threw her head back and bellowed out a whinny as the glorious release tore through her. More cum jetted forth, surging deep into the hellhound's womb. Loona's own voice cried out in a long howl of pleasure, orgasm crashing through her as well. Her pussy spasmed around Trixie's shaft, milking at it as Trixie shot forth more streams of semen.

Trixie shuddered and twitched, barely capable of controlling her limbs as the mind-numbing blasts of pleasure wracked her body. Her cock poured out another torrent of cream, and another. Loona's pussy gripped tightly around her knot, welcoming the whole of Trixie's cock into her body and accepting each gout of sperm with eager quivers. It was all so good, a heavenly storm of sensations carrying her away.

Trixie trembled atop Loona, riding out her orgasm in a timeless period of ecstasy until her cock spit forth the last spatters of semen. Even though she felt as if her balls had pumped a gallon into the hellhound, her cock fit so snugly in Loona's pussy that not a drop had leaked out.

It was a pleasant feeling, to have her cock embraced in that warm wetness. But Loona seemed like she was still cumming, her body shaking as little aftershock orgasms rippled through her body. Her pussy kept quivering and clenching around Trixie's cock. Trixie felt proud to have brought the creature to such a finale, but she herself was rather spent now.

She took a moment to catch her breath, then shoved back to dismount.

But Loona's pussy was still tightly wrapped around her knot. Trixie felt the muscles in her groin stretch painfully as she tugged at her trapped cock. At the same time more ripples of Loona's flesh teased at her shaft, keeping it hard in its fleshly prison. She'd just cum, but the feel of Loona's slick walls quivering at her kept her weary nerves overloaded with pleasure.

She tried to pull back once more, but there was no escape. Her heart pounded in growing panic. “Loona? I... I'm stuck...!”

The hellhound sagged to the floor in front, laying her head along her crossed arms as she panted in bliss. No help there. The relentless grip of Loona's pussy was having its way with her cock as well, and Trixie felt the renewed pulses and twitches as it tripped into a fresh orgasm. More semen spewed from her, erupting in sudden, savage pulses, the pleasure like a lash. She gasped as it hit, her vision blurring for a moment as her unprepared body spasmed and her seemingly drained balls managed to muster forth another load of cum.

“Fuck yeah,” Loona groaned. “You tied pretty well, Trixie.”

She felt wobbly as the orgasm trailed off. She was still lodged firmly in Loona's pussy, and the wet cavern still seemed intent on working her cock over even more.

Trixie reared up shakily, looking down her chest to see the juncture of her cock trapped in Loona's pussy. Maybe seeing it would help her figure out how to escape. But her body was still recovering from the last orgasm and she felt herself tipping off balance. She threw one hind leg up to try to regain her center of gravity, throwing out her forelegs as well, but the next thing she was falling, throwing that leg across Loona's back as she twisted and came down in a clatter of hooves and yanking the hellhound's rump to the side with her.

Loona howled out in ecstasy.

Trixie sprawled on the floor, rump up and shoved back against Loona's own ass, the hellhound's butt cheeks pressing warmly against her own. Her cock was still buried inside Loona. She was pretty sure that a stallion's cock wasn't supposed to bend like this, but this one seemed to have no issue jutting straight backwards from her groin.

And the shock of that sudden fall sent her cock jerking and spurting another blast of cum, hitting Trixie with a hard orgasm that made her whinny at the wrenching pleasure.

“Goddamn, Trixie, you're a natural,” Loona gasped out.

Trixie could scarcely understand what the hellhound was saying. She was locked butt to butt with Loona, the hellhound's bushy tail pushing up at her own. And all the while Loona's merciless pussy kept milking her cock greedily.

It went on and on, for nearly half an hour. Trixie was dizzy, barely coherent, her whole body trembling as Loona forced countless more ejaculations from her. The pleasure was an agony of overstimulation, the torment an endless train of thrilling surges. She had nothing left to give, but Loona compelled her exhausted balls to keep squeezing out spurt after spurt nonetheless.

Trixie was babbling incoherently at the end of it, her mind so jumbled that she did not even notice at first when Loona's pussy grew quiescent, sated at last on the outpourings of Trixie's semen. She only came back to herself when she felt the knot slipping free at last, having finally shrunk from its engorged state. Her cock slid out of Loona and she flopped to the floor in complete exhaustion.

She managed to scrabble at the stone flags and turn herself enough to see the hellhound. Loona too was flat on the floor, face down and with her hind legs parted. Trixie could see the creamy white cum oozing from the slack lips of Loona's pussy, frosting the white fur of her thighs.

But after a moment Loona rolled over and sat up. She crossed her legs and stretched out her arms, throwing out her chest as she breathed deeply. “Ahhhh, I needed that,” she said.

Trixie felt the dick spell wear off then, the mass of flesh at her groin dissolving like a burst of bubbles in a glass of cider. Good to know it wasn't permanent, she thought belatedly.

“Trixie can barely move,” Trixie said.

Loona stood up. “No complaints then, I take it.” She walked over to the summoning circle.

“It wasn't quite what Trixie was intending, but very effective nonetheless.”

“Heh. Maybe next time I'll summon you, oh great and fuckable Trixie.”

Trixie's eyes widened. “Please don't!”

Loona snorted. “You can send me back now.”

“Right,” Trixie said. She managed to draw up a spark of magic from her horn. “O infernal spirit, return thou now to whence thou came from.” A sudden odor of brimstone flowed past her nostrils, and the dark red smoke began to billow up around Loona.

“Oh yeah,” Loona said as she began to fade, “Magic sperm isn't usually viable, but on the off chance you knocked me up, Blitzo is going to track you down and carve out your spleen with a rusty spoon. But it's probably nothing to worry about.”

“Thanks for the warning,” Trixie murmured as Loona disappeared with a final popping noise. She lay on the floor for a long time, recovering her strength. That had been awful. The most ridiculously extreme fuck of her life! Loona's dick spell was a danger. An absolute menace!

She licked her lips.

Starlight was going to be so surprised!
