The Other Kind of Demoness (Demon Girl Transformation)

It was around quarter to nine in the evening that Gabe finally arrived at Blake’s house. The two had met when they were twelve; although the responsibilities and stresses of adult life had started to interfere with their relationship, they always managed to keep in contact with each other no matter what. It was when Gabe suddenly received a couple messages on his phone that he decided to meet his old friend again in person:

[Blake] - Hey man, you busy right now?

[Gabe] - Nah, not really. Just chilling.

[Blake] - You mind coming over to mine for a little while? Feeling a little shitty.

[Gabe] - Sure - is everything OK?

[Blake] - I’ll explain when you get here.

Approaching the large white door, Gabe thumbed the doorbell and waited. A couple moments later, there was movement behind the frosted glass panel and then it was opened, revealing a young blond haired man. Blake had a rather robust physique that was only enhanced due to the simple grey vest and cargo shorts he was wearing - in many ways he was the opposite of Gabe; who had dark hair and looked like a twig standing next to his muscular friend.

“Blake… is everything OK?”

“Come in,” he sighed, stepping back to allow Gabe to duck inside and head towards the living room.

Gabe sat on the white leather sofa that was across from the one Blake had been sitting on, his hands clasped and resting on his knees. In the background, the large television was currently broadcasting the news, which had just started it’s sport section. As the two men sat in an awkward silence, Gabe glanced over at Blake and was surprised at how stressed he looked; as if he wanted to just meld into the sofa and disappear.

“The boxing match is gonna be starting soon,” Blake suddenly remarked, his body relaxing slightly as he glanced at Gabe. “You uh, wanna watch?”

“Um, sure…” Gabe replied before shaking his head and adding; “Blake, what did you wanna talk to me about?”

Blake sighed, his eyes peering down at the floor. “Right… Gabe, would you say I’m a hit with the ladies?”

“You, Blake Winters, a hit with the ladies?” Gabe scoffed jokingly. “Yeah right!”

He was quite taken aback when Blake, instead of laughing or smirking, shot him a steely glare.“You know I’m joking, right?” he added. “I’m pretty sure you’re aware that girls have been staring at you since you were sixteen.”

Blake’s gaze immediately softened and he shuffled in his seat for a couple moments. “I’m sorry man. It’s just that recently - recently I haven’t… Y'know, been lucky.”

It was Gabe’s turn to glare at Blake, though his was more dumbstruck than anything else. “That-that’s it?” He said. “Dude, just because a couple women have been rejecting you doesn’t-”

“It’s not just a couple women, Gabe!” interrupted Blake. “It’s actually been going on for some time now.”

“How long?”

Blake shrugged. “Three, four months?”

Gabe shook his head. “So what? Just because girls aren’t jumping you and ripping your pants off the second you enter their vision doesn’t mean you’re never gonna get laid again.”

Blake blushed. “Y-yeah, I know that…”

“So what are you worrying about?” Gabe then pointed at himself. “I haven’t even done it once; you don’t see me spiralling into depression.”

The two men chuckled for a good thirty seconds before Gabe managed to compose himself. “I’m probably gonna sound super cheesy and adulty for a second, but…”

“Aw, don’t say it…”

“But maybe you should try and stop searching for a while.” He suggested. “You’ve got the looks, but I bet when you’re talking to these women they can tell you’re as thirstier than an alcoholic during the Prohibition.”

“The what?”

“My point is they can tell how desperate you are the second you enter the room - maybe if you stop searching and thinking about it for a while you’ll calm down.”

“I guess I’ll give it a shot…” Blake said before suddenly perking up and looking at the television. “Looks like the boxing’s about to start - guess now’s a good time to forget about getting laid, huh?”

Smiling, Gabe simply huffed and nodded. Although he wasn’t that much of a fan of boxing - he found it a bit too dangerous and violent for his taste - he decided to stay and watch the match in it’s entirety for his friend.

Ten minutes had passed and whilst Gabe was still casually watching the match, Blake was now sitting on the edge of his seat; completely engrossed in the ongoing match. Although he had no idea who his friend was rooting for, Gabe simply assumed that it had to be the guy who’d been effortlessly dominating his opponent since the very first second of the match.

“Hey man, you want something to drink?” He suddenly asked. “Got some beer in the fridge.”

“Oh, no thanks - I gotta walk back home, remember?”

“It’s cool man, you can just stay the night or something.”

“Oh, OK then.”

Blake then left the room; Gabe heard the clinking of bottles as they were pulled out of the fridge followed by a soft pop as one of the lids was pulled off. There was also the creaking of a cupboard door opening and closing, but Gabe was confused when Blake returned a couple minutes later with just two beer bottles in his hands.

“You didn’t get any snacks?”

Blake froze just as he was about to sit back down. “Hmm?”

Gabe scratched the back of his head. “I mean, you were in there for some time... I thought you were getting crisps or something.”

“O-oh. Well um, I did look but there wasn’t really anything there.” Blake sputtered as he shoved one of the bottles towards Gabe.

“I think you gave me your bottle.” He said before handing it back , but Blake just shook his head and sat down.

“N-nah man, it’s yours - consider it my way of thanking you for coming over and helping me.”

Gabe raised an eyebrow. “Are you trying to wriggle out of owing me a favour?”

“Shit, you got me!”

The two chuckled, clinking bottles before taking their first massive gulps - Gabe suddenly spat some out and started coughing, causing Blake to jump out of his seat.

“Oh shit! Gabe, are you OK?!”

“Yeah, I’m fine.” He croaked, clearing his throat and wiping his eyes. “I wasn’t expecting that to taste so…”

Blake gulped. “So what?”

“…So good.”

“Whaddya mean?”

Gabe shrugged, examining the bottle. “I dunno. It had like, more of a kick to it or something - where’d you buy this?”

Blake took a swig from his bottle and sat back down. “Same place I always do, from the corner shop. Want me to get you another?”

“Nah, I’m good.” Gabe nodded at the TV, smiling playfully as he did so. “Anyways, you’re gonna miss the match if you keep talking to me.”

Muttering an “Oh shit!” under his breath, Blake immediately resumed watching the screen. As the match continued, Gabe quickly emptied his bottle - usually he drank at his own pace, but there was something so good about it that he couldn’t quite put it down.

As the match continued Gabe slowly found himself becoming more engaged with the match, his eyes didn’t want to look away and when they did they were immediately drawn back in by the boxers; there was something about them that suddenly seemed so… intriguing: He could see the power behind each blow, the way their muscles rippled with every step and breath they took, the way their sweat trickled down their abs - Gabe paused. Why was he suddenly so… fixated on the boxers? It was only now that he noticed the growing tightness in his groin; he didn’t need to look down to know what it was.

“Hey uh, where’s the bathroom?” he asked Blake, crossing his legs to cover himself.

Fortunately, Blake eyes remained glued to the screen as he nonchalantly answered; “Go down left, the second door you see.” Gabe sprang out of his seat, quickly shuffled out of the room and into the hallway, finding himself having to press a hand against the wall as his vision started swimming and a tight, dull ache pulsed around his forehead - since when had he become such a lightweight?! Managing to stumble his way into the bathroom without collapsing to the floor, Gabe locked the door and groaned quietly as he unzipped his trousers to give his uncomfortably erect member some well needed breathing room.

It was only when he sat down on the toilet and felt the coolness of the porcelain that he realised how clammy his skin felt. But he wasn’t too worried about that, as he was currently occupied with gazing at his penis with bewilderment. Why the hell was he so hard? If he were still in his teens he would’ve chalked it up to hormones, but he was twenty three years old! The time for awkward boners was supposed to be long gone now!

He knew he couldn’t just stay in the bathroom forever, but his dick didn’t feel like calming down anytime soon: There was only one way to solve this problem. Embarrassment and shame flushing through him, Gabe began to masturbate. As he began to stroke his manhood, his mind began to steam up with all kinds of women before focusing on the ring girls with their tight cleavage and round asses.

Scenes of them being fucked by the boxers began to flow through his mind, but as he continued to get off his perspective began to change from the horny boxer hungrily taking what was his and into the ring girl’s desire to be pinned down and taken by such a strong and powerful force. A pang of worry sparked in Gabe’s stomach, but he dismissed it easily - he knew he was straight but he couldn’t deny how… taboo it felt to be getting off to such thoughts, especially in his friend’s home-!

Gabe’s mind suddenly flooded with images of Blake as he had a revelation about his body: How had Gabe never noticed how muscular Blake had become over the years? He imagined Blake bending him over, watching him squirm with anticipation before he had his way with him - It was this image that caused Gabe finally go over the edge; he bit down on his lip hard as he unleashed what would be his final masculine orgasm, every wave of bliss coursing through him causing his testicles to shrink inwards.

His mind hazy from the afterglow of such a powerful and the booze, Gabe peered down and sighed with relief at his now completely flaccid penis before zipping himself up. As he flushed the evidence of his deed away and approached the sink to wash his hands, a small and concerned voice in the back of Gabe’s muddled mind noted that it had looked much smaller than usual - although after it had spent the past five minutes being harder than diamond, Gabe wouldn’t have been surprised if it didn’t even twitch for a damn week.

Still feeling sweaty and a dull ache , Gabe cupped a handful of water and slapped it onto his face, savouring the coolness as he massaged his skin. Pulling his hand away, he gasped at the small drops of blood on it and darted his head up to inspect himself: A rivulet of blood was weeping out of his bottom lip; no doubt from his pleasurable experience minutes ago - damn, he never knew his teeth could be that sharp!

Dabbing and wiping at the cut with his silky smooth fingers, Gabe continued to stare at himself in the mirror as the concerned voice returned again to tell him that something else was wrong, but he couldn’t really see it: He had brown hair, pale skin and green eyes -

His eyes. Moving up and leaning his head in as close as he could to the mirror, Gabe stared directly at them: Not only were they quite bloodshot, but he could’ve sworn his usually “leaf” coloured iris were brighter, more “neon green”… He shook his head and pulled away before leaving the bathroom - it was probably just the lighting and drunkenness settling in.

Calmly returning back to the living room, Gabe’s brain made the split-second decision to sit down next to Blake - he wasn’t sure why, but it just seemed more… comfortable than sitting all alone on the other sofa. Instead of just crossing his legs or sitting normally, Gabe unconsciously curled his legs up on the sofa and rested an elbow on the armrest.

“So um, how’s the match going?” He asked, not even bothering to look at the screen as he waited for Blake to respond, his heart flickering when he saw those icy blue eyes lit up as they turned to face him.

“It finished a minute ago. Seriously man, you shoulda seen the way McCoy went flying after Samuels hooked him!”

Gabe smiled as he began to realise how just cute Blake was when he was excited, as well as how the slight stubble sprinkled across his jaw made him so… irresistibly manly. A nervous giggle escaping his lips, Gabe quickly looked away before he could start blushing, feeling butterflies starting to dance around inside his stomach. This light-hearted tingling was quickly deadened by a horrible bloatedness; Gabe pouted as he put his legs back down and sat straight, hoping that it would go away soon: Unfortunately, the feeling only continued to worsen as Gabe’s withdrawn testicles morphed into ovaries; he groaned and clutched his stomach at the unfamiliar twisting sensation.

“You OK, Gabe?” asked Blake, placing a hand on his shoulder.

There was something about that voice now that Gabe couldn’t lie to; he shook his head. “Something’s wrong, I don’t feel-”

Blake leaped away from Gabe, his eyes wide. “Dude… You just sounded like-like a chick!”

“What do you mean I-!” Gabe gasped and covered his mouth. His definitely voice sounded higher - girlier - than before; his adam’s apple had completely disappeared. The two of them stared at each other in shocked silence and before either of them could say anything, Gabe suddenly cried out in pain and fell to the floor, curling up and wrapping his arms around himself as a tight pulling force appeared around his waist.

“Gah, my hips!” He shrieked in his new girlish tone. “Blake, call an ambulaaaaahhhhh!”

Gabe’s pelvis began to stretch outwards whilst his shoulders caved inwards, the bones creaking and snapping like wood as they shifted into a slight hourglass figure; leaving him with a scrawny yet undeniably girlish body. Vibrations suddenly enveloped his arms and legs as they corrected this imperfection, kneading his flesh as it filled and thickened like bread in an oven, accentuating his now fertile hips and inflating his flat ass into a bouncy bubble butt. Hidden by his shirt sleeves and his stretched trousers, all the body hair on Gabe’s body had been pushed out of their follicles by this change, leaving his skin nice and sleek.

Although the sensation was completely bizarre, Gabe had to admit it had felt rather… stimulating. Curious, he drifted a hand down to his backside; moaning at how pliable his butt felt, having either forgot or just flat-out not caring that he’d just groped his ass in front Blake, who was completely dumbfounded by the transformation occurring in front of his very eyes.

A dull weight started forming on Gabe’s chest and he instantly knew what was coming - in fact he now relished it. Moving to rest on his elbows and deliciously soft rear, Gabe licked his lips, stared hungrily at his shirt and waited: Waves of pleasure flew through from his nipples and down into his groin, causing the small stub of his manhood to wriggle uselessly as it started to submerge itself into her moist lips.

“Oh fuck yes!” She hissed, her voice having now gained an supernatural reverb to it. “It feels sooo good~”

Gabe’s body temperature began to rise with each pulse and the clamminess from earlier returned, his skin gradually reddening. The heat and the pleasure proved to be an overpowering combination and she slipped a hand inside her trousers, her breaths quickly becoming sharp and laboured. With each gasp, her chest would puff out even further than the last as it filled then strained against her top. By the time her breasts had reached a generous D cup her skin had turned completely scarlet.

The heat suddenly converged on Gabe’s groin as a large wave of pleasure surged through her; she wailed as her first female orgasm finally came. As she writhed and shuddered in rapture, her short brown hair blackened and cascaded down to her neck.

“Mmmph… so good…” was all she could mutter.

Meanwhile, Blake was still standing there in complete awe. “I.. I can’t believe it worked!”

Gabby was pulled out of her post-orgasmic bliss by the sound of Blake’s voice. “What?”

“I bought some potion off this guy a couple days ago after I’d been rejected by a girl again,” he explained. “Had a weird ass accent, but he told me that whoever drank this would turn into a horny woman. I didn’t think he meant it so literally but hey - you’re hot now; that’s all that really matters.”

Gabby gasped as everything came rushing back to her: She wasn’t a demon - she wasn’t even supposed to be a girl!

“W-what the fuck did you to do me?!”

Blake lunged at Gabby, pinning her down with ease. “Don’t try to struggle!” he said, kissing her cheek forcefully as Gabby tried to move her head away. “I’m doing you a favour anyways - you said you’d never had sex before and now you’re about to!”

“N-no, get off me!” She squealed, helpless to stop Blake from forcing his tongue into his mouth. As she flailed and kicked, an emotion started to manifest inside Gabby: It wasn’t fear, heartbreak or lust: It was anger, it was hatred… It was wrath.

“I said GET OFF!” She roared; sending Blake flying into the hallway with a single push. She tried to stand up but found herself falling onto her knees as she was overwhelmed with an intense, ardent emotion.


“You… You made me come all the way here…” She seethed. “Spiked my drink… Just so you could get a quick FUCK?!” Gabby punched the floor on that last word, the force behind the impact causing her fist to break through the wooden floor with ease.

“What the fuck…?” Blake coughed, groaning as he stood up. “This isn’t supposed to happen!”

As a dull throbbing wrapped around her forehead, images of the boxers started to race through Gabby’s mind again but this time she wasn’t lusting over their muscles - this time she wanted to have those muscles for herself! To see and feel that power flowing through her with every step she took! The sheer strength to take what she wanted when she wanted! That was so much more arousing! Gabby’s slender, thick body began to bulk and morph as muscles replaced fat - realising that now wasn’t the time to be gawking, Blake quickly scurried into the kitchen.

“That son of a bitch lied to me!” Blake snivelled as he flung open a cupboard and snatched a small brown bottle, reading the back of the wrapper for any kind of advice:


“~Mr. Mephistopheles’s Marvellous Mixture!~

Just one or two drops of this in any consumable is guaranteed to make anyone* who drinks this into the horny woman of your dreams**!

*And by anyone, I literally mean anyone.

**If you’re reading this cover it’s probably because your target turned into a regular demon instead of a Succubus - what’s wrong with you? Not ALL female demons are Succubi, you know!”

“Oh, fuck me!” Blake cried.

“Blake…~” growled a deep, feminine voice. Blake turned to face Gabby and what he saw made him drop the bottle, causing it shatter as it hit the floor, the red liquid fizzing as it came into contact with the air. Although Gabby was still a female demon, her form had changed: Gone was the curvy goddess from earlier, the amazonian Goliath standing in front of Blake now easily towered over him by two feet, and the thick ram-like horns that now perched on her forehead only served to emphasise the intimidating difference in height. The tight, thick muscles now adorning her limbs had teared her clothes apart - the dark blue shirt still clung tightly to her chest, emphasising her cleavage and hinting at the hard six-pack underneath. She began to trudge towards Blake, her green eyes glowing with a mixture of desire and fury.

“St-stay away from me!” Blake yelled as he moved backwards, almost tumbling into the kitchen sink.

Gabby pouted. “What’s the matter Blakey? I figured you’d like a girl with a bit of fight in her~” Blake threw a punch but she instantly caught his fist with a meaty, taloned hand and chuckled darkly as she effortlessly pushed it back.

“Watching boxing all the time doesn’t make you a boxer, babe.” Then she grasped Blake’s neck and lifted him into the air like he was nothing. He punched and scratched at her arm, but he might as well have been tickling her with the amount of pain he was inflicting.
 
“You know, I should kill you right now for what you’ve done to me,” she hissed, her grip tightening. Blake croaked and gasped, vision blurring as his eyes watered - Gabby laughed as she ravished in her newfound strength.

“But I won’t.” The grip loosened and Blake coughed as air flowed back into his lungs. Gabby then hoisted him over her shoulder and stomped down the hallway, kicking Blake’s bedroom door off it’s hinges and chucking him onto the bed - before he could even move she pounced on him and pinned him down.

“I might not be a Succubus, Blake,” She purred into his ear as she ripped open his shorts and gripped his manhood, causing him to whimper in a confusing mix of fear and arousal as he felt how tight and warm her hand felt around his length. “But I promise to do my best at the whole "death by fucking” thing, ‘kay?“
