Sweetie the Succubus

Story by Catullus16 on SoFurry

, , , , , , , ,

In an underground fighting tournament, Big Mac wagers his balls (or life) on his ability to outlast Sweetie in a sexual encounter. But if he doesn't take the teenage filly seriously, he'll find himself in big trouble.


Warning/Clarification. The characters in the following story ARE OF AGE. Sweetie is 19. Big Mac still SEES her as a kid. That doesn't mean she IS a kid. She is of age, and PLAYING on her youth.

Furthermore, this story includes death and threats of castration. Thought you ought to know.

Based on an RP with IsisAzza on FA, so, to use a euphemism, thanks to Issy for his help preparing the manuscript.


The cavernous underground arena was filled to the brim tonight, waiting for another vicious match...didn't matter if it was a hate-filled grudge match, a playful teasing match...really didn't...only the fact that it always ended with someone getting permanently maimed or crippled...that was what kept them coming back.

Sweetie, the sexual queen known as 'The Succubus' was already in the dirty, blood stained pit, while the audience cheered from above, separated by rusty wired cage fences... dressed in her cute lil demon costume, adorable enough that it was hard to see just how sharp the heels of the boots were, cut in all the right places to show off the matured curves of the now-teen filly, who still had a youthful look and air by her sister.. "Hey there, Big Mac~" She waved cutely, strutting towards him playfully.

Mac was in blue jeans, and no shirt, Letting everyone see his powerful looking body, the massive bulges of muscle moving as he did, this looked like a total mismatch. And if they just stood and fought, it would be., she'd have her face ground into the dirt. But it wasn't. This was a sex battle... He'd be fighting to keep his cum from her. Something that the excited crowd knew no stallion before had managed. Plenty of studs had been milked out, and forced to wear her collar after failing the "Succubus Challenge." But they kept coming back. It was such a tempting offer. A million bits, if you managed to handle someone so small in a sexfight. But if your balls weren't up to the task, well, she'd take them. There was a reason that Soarin's flight suit was so form-fitting... He'd tried the Succubus Challenge and, well, she'd left him a lot more aerodynamic than when he started. "Hey Sweetie..." He said, getting aroused despite himself. Even though he knew consciously how old she was, he still saw her as a filly.

"Nice to see yah~" Sweetie grinned, turning around when she was close to him so her ice-cream colored tail would brush against his nose. "Wave at the pretty princess, would you~?"

Princess Celestia sat in the good seats above the ring, looking coldly down into the fight pit. "Ah, Big Mac. Now this is one fight I will certainly enjoy seeing."

He gave a wave to Celestia... And a bit of a dismissing grunt at her comment. He doubted Tia would really enjoy him battering the poor little filly around, then fucking her... But he'd do what he had to do, for his lover.

"Why are you even doing this, Sweetie, don't you have school?"

"Nope~ Found a job right here." Sweetie turned around and grins. "So!" She extends her hand out for Mac to shake. "I'm looking forward to fighting you tonight."

He shook her hand as well, "Looking forward to it" He said apprehensively, admittedly he didn't enjoy the idea of trying to fuck a filly, but... It was a million bits.

The little demoness nodded...and then she tightens her hand around his. Suddenly she leaps, trying to catch Mac in a standing arm bar!

She pulled his arm down in an armbar, and he did his best to keep the joint from getting over-extended. It was, admittedly, fairly easy. A filly could only pull so hard, which was his advantage.

Hers was that a stallion can only fuck so long before his frothy white defeat coats his cock and balls, forcing him to submit to the nightmare before him or lose his life to his inferior sexualit.

"Nnnghhhh..." Sweetie grunted cutely, looking up at him, wrapped around his arm. "Give up yet?"

"D'awwww~" The crowd let out an adoring sigh. But it was less a simple reaction to her weakness, and more like a pre-expected crowd reaction, like fans chanting at a wrestler's theme.

He looked down at her... Then raised his arm, and slammed it down again, relishing in seeing her eyes widen at the lift, and the agonized cry as she smashed into the dirt with so much force a cloud of dust flew into the air. The crowd cheered!

"This is ridiculous, sweetie, you can't expect to beat or fuck me, you're just a filly."

Sweetie moaned, but eventually she sat up weakly. "Oh, but I do...just watch me." She says...before lashing her foot out, trying to catch Mac in the nuts! The giant of a stallion doubled over, grabbing his crotch and crying out in pain. Oh hell did that hurt, she hit hard, and save some jeans and light boxers, he was defenseless.

"Mmmm....see?" Sweetie said in a soft, tender voice as she rose to her feet and dusted herself off. "I wonder if your balls will last the match...hope they don't rupture or anything...that'd be really bad, won't it?" She asked innocently, leaning forward to look at Mac suffer.

"That wasn't nice." He scolded her, still acting like an adult talking to a child, rather than a man up against the most dangerous opponent he ever had, and likely the last he ever would.

"Aww, sorry Mac, didn't mean to kick you there. I was actually trying to get you here!" Sweetie's sweet voice turned sinister as her voice lashed out again, this time catching him right in the nose! He stumbled back a bit, not falling, but her foot had struck with surprising force for the teenage mare. He glared at her... Stepping forward again, to try to get his arms around her body, pull her up into a bearhug. Unfortunately for him, if there was one thing Sweetie had, besides no fucking empathy at all, it was speed! She dodged around the big stallion easily, and then, using her momentum, she lept into the air to plant both her heeled boots into his ribs!

She nailed him perfectly, and he fell forward... He couldn't believe he was struggling to beat Sweetie, of all ponies... This was ridiculous, he hit the ground clutching his chest.

"Aww, did that huwt, big guy~?" Sweetie gave an exaggerated pout, and ruffled his blonde mane. "Really sorry I hurt you like that..." She giggled and looks over to the purple patch on his side...Oh that was bruising nicely. "Lemme make that better~" She gave a sick smile and launched another knee right to that spot!

He got smacked again, rolling onto his back after that... Fucking kid took him down! He tried to get back to his feet, but it was slow, his ribs on fire after that strike to his side. He was both embarrassed and angry, and glared at her. "I won't let you treat me like this. I'll send you home with a spanking!"

"Oh, please do, Mac, I would so enjoy that~" Sweetie turned around and wiggled her thong-clad tush at him, her tail swayed invitingly behind her, beckoning him closer. "That is, if you can even get up." She chuckled.

It was hard to believe that this was a lucky break in a fight with a filly who just two years ago had been too young to even HAVE sex, much less become a sexual queen known as "The Succubus." His hand slammed her flank, hard enough for it to be heard by everyone... And through it all, as powerful as he is, he couldn't shake the feeling she's toying with him... Like this match would end as soon as she decided the time came.

"Haaaahhnn!!!!" Sweetie moaned, and Mac realized that wasn't pain she felt. Or not only pain. She turned to face Mac with a sultry look in her eyes. "Feels good to smack a filly hmm?" She wiggled her ass again...then hissed. "HARDER!"

More rage and humiliation burned through him, and he glared at her, going to pull back on her mane, now, and smack her again... With all the power in his trunk-like arm, enough almost to take a tree down just by hitting it, he slammed that sexy white pony ass, trying to punish her for her rude and impudent behavior.

Sweetie yelped a little when her mane was violently pulled, but when that strike came... Oh Celestia, did she ever scream. Her ass instantly turned to a bright pinkish-red, and it was definitely gonna bruise in the morning. Her grin morphed from ecstacy into a firey glare, matching his every bit, and she slammed her costumed heel into his foot.

He got stomped, but didn't let go, giving her another spank... She wants spanks, she'll get them. At least until she turned this back into her fight, one where it's a man's cock against the body of a woman who earned the title of succubus in the most natural way. By fucking men's cocks until their balls shriveled and hearts gave out... And even if they survived, she'd make sure she was the last fuck they ever had.

"Oh Maccy, you're OWCCH, fuck! ...Testing my patience..." This time she lifted her foot high enough to dig that heel viciously into his hip, and dragged it all the way down, tearing into the muscle and flesh of his powerful leg.

He cries out as she cut a bloody gash in his thigh, ripping the jeans as well... He had to let go of her, he really wasn't expecting her to put up anything near this good of a fight, not only fighting back but slicing his muscles and flesh.And that would seem to be his problem as she gets to work beating on him

"Mmmmm...Heard that, hun~" She gave him him a sick grin, then went straight for his knee, the spiked heel striking the kneecap, hard enough to put a crack, blood pouring from his leg now.

Why was she doing this? He fell away from her in pain, blood dripping from his leg, feeling on fire from the damn little demoness's strike. He couldn't help his reaction. "You bitch!"

She gasped in mock horror. "Mac! Did you just call me a b-bitch? How could you???" She held her hand to her chest in an exaggerated manner, as if he'd hurt her bad! "What did I ever do to deserve that?" But then she shook her head and laughed. "Oh well, lemme make it up to you!"

She gave another of her wicked grins and hopped over, and like a rabid timberwolf, she went for his jeans, ripping at the button and zipper, trying to get them off. He couldn't fight back against her attempt to strip him, still grabbing his agonized leg. He could barely put up a token effort between the pain in his thigh and the rapid force of her attack.

He looked to the light above, only to be greeted with cheers, jeers, and masturbating mares and stallions. "Fuck him good, Sweetie!" "Milk him dry!" "Bust his nuts!" And Celestia just watching, sipping her tea. She knew where this is going. Mac would be wise to know that as well. Clock was ticking. Would he defend himself, or was he doomed?

Sweetie tossed his jeans away. "Take your underwear off, big boy. Gotta surprise for you~"

Fine... If she wanted to fuck, he could fuck her. He hated to hear people booing him like that. He normally drew strength from being cheered, but he just got angry from being boo'd. He wanted them to shut up, and if fucking Sweetie was what it took for that, then fine. He'd do it.

Seeing this, the crowd cheered. Now the show was starting. There stood Mac in all his full nude glory, bleeding, leg feeling like it was burning, sweating heavily...Foreplay was over. His opponent removed her panties and corset, rudely tossing them at his chest, before she approaches him dangerously. "Now let's play, Maccy..."

He was on his feet, staring down at her... Looking her in the eye... She only came up to his powerful, muscled pecs. He was glad to hear the crowd cheering... Soon they'd be cheering for the man who was able to take and beat the Succubus Challenge.

He felt her lips press to those chiseled abs of his, and she reached down to grab his big, thick cock in her hand, stroking it nice and slow. "Not struggling, huh? I don't mind...."

He gave a satisfied murr and and grabbed her by the mane again... Even he'd have to admit, it felt good to be up against her like this, her hand... Well, it was skilled. But he had almost two full feet of cock to work with. "Why would I struggle? The worst that'll happen is I'll piss of Rarity, and I've beaten her into the ground before."

"Oh, she remembers...I still hear her masturbating at night and screaming your name...Too bad after this, you won't have much to offer her, huh?" Sweetie spoke in an almost casual manner while picking up the pace. Her head lifted to look up to him. . "You won't win...."

Despite himself, he had to admit she felt good. He'd have to fight back. He reached down, groping between her legs, feeling her already nearly dripping wet from arousal. He was thankful for that, of course, but just as much so afraid at knowing how aroused beating him down had made her. His fingers slid deep into her, and the muscles in her pussy seemed to flex and suck at his hanf "Oh, I'll have plenty to offer her... A mansion, all the clothes she'd want... I'm gonna beat you, and take the money..."

"Nhh.." She let out a soft moan, "Too bad for you..." Her eyes shot up to his, "I've already given sis all that!" And her hand began pumping faster!

His cock was standing at full attention, now, as he fingered between her legs... Trying to punish her for this mistreatment of him and his shaft... Trying to push around the filly pussy with his fingers, but everyone watching could tell... This was a guy struggling to keep in control, and he was shifting his weight around, trying to focus on her. "Then I'll teach her sister not... To be such a brat!"

"Hah! You talk big, Mac!" He heard arousal in her voice, which gave him faint hope. His fingers were big, and she was struggling to handle them. Her cunt drooled on them as he worked them deep inside her. He had a chance... Until she added her other hand to the mix, and soon she was working him like crazy! "I wanna hear you talk like that when I've got my dildo up your ass!"

He groaned out, and was now bent forward over her, not able to keep up his fingering, FUCK... How was she this good? So young? Barely old enough to fuck at all? Gahhh, how COULD she be this good... So good that she was able to milk every man she met into willingly letting her castrate them, because at least if they didn't HAVE balls, they'd not be in pain from trying to keep pumping cum for her

"Awwww, somepony needs to release? Hmm~?" Sweetie asked, her tone low and husky. Despite the occasional twitch her body went through from his pleasure-paralyzed fingers stuck in her, her pussy sucking on them... But Mac was close, very, very close. "C'mon, big boy...show me how much those apples can store..."

Soon, despite his best efforts, despite all his attempts, he was on the edge for her. Round one's about to end of their little fuckfight, and it'll end up a sexual slaughter... After all, how could his cock hope to survive the night, with how close he is... He was pressed up tight to her, feeling his balls bounce like a missed tennis shot, trying to stop the cum he felt rising through his shaft.

"Oh, Mac, Mac, Mac, you should see that desperate look in your eyes...Here, let me just.." Suddenly, she squeezed his malehood hard, while her other hand slapped against his nuts! "Help you out..." Her hands rocketed up and down that monstrous shaft, now, and there was no denying it. He screamed out for the crowd as she sent him over, his balls just bursting, pumping cum out onto her... Staining his Rarity's sister with a veritable ocean of hot, studly cream!

And the woman working him off laughed as she was splattered with a massive amount of hot, steamy, creamy cum, not even seeming to care that it would stain coat, her mane, for possibly days it would be so hard to get out. So much cum was pumping from his thick shaft, making her look like she was bathing in cream.

He slumped against her, his body almost nearly resting on her in the aftermath of the first of many orgasms the filly would force into him... The first of many explosive cumshots he'd have to give up, his balls are throbbing, but he's still going... Well, at least relatively strong... Relatively compared to where he'll be eventually... He looks up at the crowd.

And now the crowd was cheering, the first orgasm of the night has been reached! Some still boo'd him, still wanting him to lose his manhood if not life to the Succubus, like so many others, but some were cheering now... Especially the mares, after his spectacular display of stallionhood, the masses of cream, they wanted some for themselves. He took heart in that... Until a raised knee sharply struck his balls. He leaned on her, now definitely for support, the nearly seven foot stallion being destroyed by this little filly, his cock is being punished... "Why... Are you doing this..." He asked, soft and low, almost pleadingly.

"Because, it's fucking hot..." She answered, whispering huskily in his ear "You wanted the bits, but now you're paying for your greed....I bet Rarity's whining pushed you here, huh...? It's all her fault, you know...you're paying the price for her prissy bitchiness, and you know it..."

She shoved him over onto his back and kneels down to start sensually licking his member, trying to get him back to full mast...

He's pretty quickly getting hard again... He was aroused and little more than a fucktoy in her arms as his cock returns to full strength... He's a virile stallion, but will his virility get sapped? "Nng... Fluttershy... Fluttershy needs... An expansion to her shelter..." He groaned as Sweetie licked him.

The Succubus only grinned. "Oh, you mean Flutterslut? She says that, yeah....but you won't really see a shelter...all those bits are going to feed her little S&M fantasies down in Canterlot...and they don't come cheap..." She licked at him again, working his powerful, rock-solid member like a piece of candy. The anger and frustration was rising in him, and he reached down, trying to grab her by the mane, pull her off... His power a bit lesser now that she'd drained some cum from his cock... His chest heaved as she licked and sucked like a little kitten on his shaft, lapping it and trying to get the cream "Nnng... Get off me... Bad girl..."

"Bad girl...oh yes...call me that again, Mac~" Sweetie moaned when the big apple grabbed on her mane. "C'mon, you're so weak...hardeeerrr..." She sneered before taking the cock in her mouth!

He grabs onto her mane harder, trying to pull her off his cock... Fucking little slut felt good working on him down there, but he had to beat her... He was going to beat her, she was just a kid and he was a giant! "Get off!"

Sweetie wasn't to be denied...when he pulled, she bit down. She wasn't going to let go, oh no, and Mac was going to have to try something else, or his big dick would meet a terrible, terrible fate. The pain coursed through his body. The Succubus's mouth was doom for cocks that entered it. There was already cum all over her face... She looked like a sex goddess, and the longer this went, the better she'd look, with cum dripping from her mouth. "Ohhh fuck stop!"

"Stop what...?" Sweetie slid him out to ask sweetly, replacing her mouth with her hand as she jerked him off gently. "This???" She asked, and then she went back down on him...and down...and down...until her throat bulged!

He couldn't even answer her, his cock is bulging, flexing in her mouth... Soon it would be going over, not yet... But soon the poor stud is going to just shoot a firehose down her throat... He clutches at the ground "Ohhh god, oh fuck, no, stop!" He screams out... Looking back to the crowd as his cock bulges in her throat, he's doing all he can... But it's a losing battle, and the sadistic filly clearly loved the sound of his screams. The more he screamed, the faster she went!

He had swelled up fully now... The last act of a desperate stud, cock seeming to double in size in her throat, scrabbling at the ground, staring into the audience through teary eyes, looking for mercy or at least concern for the poor stud being sexually humiliated, the ultimate specimen of manhood falling to a filly... "Please.... Please..." It was time to power him over.

The filly grinned. Mac was doomed! His cock had swelled in her throat, pressing in against its walls, and he heard her laugh around his shaft as he writhed. Both her hands reached up to cup his nuts and roll them in her fingers...then at last, she squeezed them as hard as she possibly could, forcing all that cream from his apples! He screamed as she milked him... His cock bucked, swelled, twitched... And blasted! It fucking exploded down her throat, another powerful, orgasmic explosion shooting gallons of seed into the mouth of his conqueror!

Her eyes widened as he flooded her, shooting so hard and fast, but being the experienced mare that she was, she gave the audience a good show by taking it all, swallowing every last bit, not wasting anything at all...gulp, gulp, gulp she went, and all the while, she didn't release his nuts, until his apple-red sack started to turn dark blue... He grabbed onto her head, holding her down, humiliating himself as he was forced into full-body spasms of orgasm by this filly... His cock was flooding her throat, her stomach, and she was taking it all... He held off a while, but all the pent up cum was turning up for her now, his balls aching. She kept drinking and drinking his cum until her belly swelled as it was filled to the brim. She had drained her man-slut good, but as she rolled his mighty balls around, they both could tell that there was a lot more in there.

After a good minute or two of sucking, he let out a low, desperate groan as she lifted her her cum soaked mouth off of his cock and gave him a dripping white smile, before swallowing the remainder... "One chance for you to get outta here, Maccy" she teased, "Climb that fence...up to the audience...escape...if you can..."

He gave a groan, clutching his cock and balls as she stopped.... Looking to the audience, trying to see what they thought of him... If he could salvage some dignity by escaping... If they'd even let him, or he'd be thrown back to the lion in the pit...

The crowd looked down and oddly, some cheered! Try to escape...they knew what was coming. Some began to chant and egg him on. Come on, climb up, climb up here to freedom!

Behind him, Sweetie just watched, wiping her stained mouth with her hand and getting all that creamy cum all over herself...tsk, tsk, tsk, so messy...

He began to crawl towards the audience, on his hands and knees... Two orgasms had taken so much strength out of him... Another one would likely break his body... Or his spirit... In time she could even kill him... Not by blood or breaking his form, just by fucking him to death... Showing him why she's a succubus...

Slowly but surely, Mac made his way towards the edge of the pit, near the chain-link cage, leaving a trail of his cum on the dirt...oh, how pathetic. His heavy, big balls swung to and fro as he crawled, as did his dick, and from the constant bobbing, he was getting hard again... Just as he began to nearly reach for the cage fence...he felt her hand on his balls, gently tugging him back to hell... "I changed my mind..."

He reached out to the crowd, pleadingly... Like someone might offer him a hand, offer him escape... Mercy, from what she'd done... And now he was going to be dragged back to the cum-soaked demoness behind him..A mere teenager, but already a wicked monster...

"Roll over, lover, and we'll finish you off nice and quick, okay?" His tormentor teased the poor man as she eyed his exhausted form like meat...one more..one more and he'd be done for... No one offered him mercy....most laughed...Celestia herself tittered...Oh, that never got old; the look of hopelessness in one's eyes...

He groaned, rolling on his back... A once-proud cowboy stud lying down for a mere teenager... A once manly beast letting her crawl on him... One more would be enough to make him tap if not kill him. Make him submit to her just at the thought she'd keep riding him... Two would surely leave an empty vessel, his very life stolen by her and her sexuality.

"Now then..." Sweetie assumed the position, facing him so she could relish his misery...her sopping wet pussy teased his tip, and she didn't wait any longer! She lifted herself up...and slammed down all the way!! "AAAHHH YYYEESS!!!!"

He cried out as she slammed herself down, riding his pole... His own cum dripping back down on his body from off of hers.If she hadn't been white before, this would have dyed her white as snow... "Ahhhh fuck!"

She gave a cruel laugh. "Gonna milk you dry...your balls are gonna shrivel up...how does that feel, huh Mac? To lose your manhood?!" Sweetie hissed as she pounded him, fucking the daylights out of him! He was sure she must have felt pleasure, but she was so trained and experienced that she held it in...her body was a weapon, used to torment and pleasure her victim, until he he expired from all the sex....Mac felt like he was hanging on by a thread now. panting and gasping for air... "Awwww, somepony gonna cum?"

"No..." He shook his head, trying to deny it, trying to deny her... Trying to deny the pleasure he felt in his powerful cock, in his emptying balls... They're half the size that they were before... He wouldn't die for this orgasm, oh no... But he would soon... For now, he was having the cum pumped by an expert... And he was close, so close... About to be sent over.

"Yes..." Sweetie replied in a seductive tone as she fucked him into oblivion....a part of her hoped he didn't die, so she would have the pleasure of making him go through the horror and agony of his imminent castration, and she wondered just if he could survive...nonetheless, she was working him good and hard now, and her pussy was like a demonic mouth, sucking and eating his cock, making him suffer so badly... She ended it, with one last shove....she brought herself nice and high, nearly up to his tip, before slamming herself so hard down her butt slammed and crushed his nutsack, crushing his poor balls.

He screamed out, and his orgasm burst into her pussy... Shooting blasts of cum into her, his body twitching and shaking, eyes rolling back, he couldn't help but look at the audience watching him... Watching him get crushed... Watching him get destroyed... Watching her pussy eat him alive.

He was gazing hopelessly at the grinning audience as they watch him orgasm into the young demoness... Their sneers and jeers crushed his spirit just as much as Sweetie has crushed his once-powerful body....He felt the pain building in his chest as his cock kept pumping his cum out of his balls. He couldn't keep up, his sweat pooling on the ground. He was being devoured whole by this demoness, her pussy chewing him up and swallowing. The agony spreading through him. She didn't say a word, she just stood up, lifting her body off his now worthless cock, slowly stalking over him to finally come to a halt above Mac's head... "You lose..." She whispered, barely loud enough for him to hear, and reached down to part her swollen pussy with two fingers, showing off her battered cunt, filled with all his spunk...a little glob of his hot, creamy seed plops down on his face, adding to his humiliation... "Give up, Maccy?"

The pain felt like a pure rose of agony. He whimpered and groaned as she tormented him. His mouth opened to try to answer her question, and he felt the tangy taste of his cum rolling into it. But the words wouldn't come out. The question was too little, too late. His last sight was of the wicked cunt that had destroyed him, a gaping maw of dripping cum hovering over him, spitting out the seed that he'd given... The life that it had taken on his poor, weak face.
