A charming costume party
Applying the last of the green body paint on her ass Gwen turned to admire herself in her wall length mirror, smirking how even when coloured green from head to toe she was still one hot piece of ass “I make being an reanimated corpse look good” the redhead smirked, cocking her hips and giving her freshly painted ass a smack
Having selected the Bride of Frankenstein as her costume for the year Gwen had gone all in, painting every inch of her body the dull ‘Zombie green’ the Bride was famous for and now all she needed to do was draw on the stitches, dye her hair black and put on the tissue thin white dress to complete the look “thank god it’s not that cold this year” she commented as she headed towards her bathroom to begin dying her hair
In his room Ben sighed as he checked the time again, having been waiting for a good couple of hours now for Gwen to get ready making him sigh in annoyance as he headed out of the room to Gwen’s “come on nerd! How long does it take to put on some facepaint?” he called out whilst banging on Gwen’s door “keep this up and we’ll be late to the party!”
Just as he had finished banging on the door it swung open revealing a now fully costumed Gwen, her hair now a sleek black and her skin now decorated with intricate stitch drawings, most likely from an eyeliner pen, her body also now clad in a paper thin, borderline see through white dress that hung from her like torn rags akin to the Bride of Frankenstein from the original movie, the dress looking like a ruined wedding dress that left nothing to the imagination as Gwen’s tits and cunt were near completely visible through it leaving Ben staring near slack jawed “whoa…”
“Damn straight ‘whoa’” Gwen stated with a slight prideful smirk “and the fuck were you doing being impatient when you haven’t even bothered getting a costume ready yourself?”
“Oh but I have” Ben then grinned back, raising his arm to bring up the Omnitrix and setting it to a specific Alien to activate it, his body growing and morphing before Gwen’s eyes, his muscles swelling whilst two large pylons shot out of his shoulders, growing inch by inch until he stood several feet taller as the towering Frankenstrike “tada!”
Staring up at him for a moment Gwen crossed her arms and pouted “ok that’s just cheating”
“Don’t blame what works” Ben smirked back reverting back to his human form so that he could actually leave the house “now come on, you’ve wasted enough time already” he teased as they headed outside, Gwen’s uncharacteristic silence giving him a small ego boost as he believed he had actually won an argument for once
Only for Gwen to stop dead as they left the house, crossing her arms again and tapping her foot whilst looking at him expectantly “ok, I’ll bite, what?”
“Carry me”
“What?”
“You heard me dweeb, I spent three hours getting ready and all you have to do is push a button” Gwen stated matter of factly before pointing down to her bare feet “and if you hadn’t noticed my costume doesn’t exactly include shoes”
“Seriously? You can’t even put sandals on?”
“And risk ruining the paint? Not a chance, now be a good boy and carry me”
Glaring at the smirking redhead Ben eventually just sighed “you owe me for this” he muttered as he brought the Omnitrix back up to transform back into Frankenstrike, the undead looking Alien then holding out his arms “just hurry up before I change my mind”
“Such a gentleman” Gwen quipped back sarcastically as she proceeded to hop up into Ben’s arms, lying in them bridal style and arching her back to flaunt her body to her cousin before waving a hand at him dismissively “go on then, didn’t you say we were going to be late?”
“Oh you are so going to owe me for this” Ben just grumbled as he proceeded to head down the street
Thankfully for Ben the party was arranged to be an outside rave in a field just outside of town and as the towering Frankenstrike it took Ben little to no time to arrive, the pair arriving to find the party already in full swing with pounding music filling the night air and all around, scantily clad party goers were bumping, grinding, and borderline fucking against all manner of ‘monsters’
“Wow” Ben commented as he caught view of a pair of girls, one in a leotard and another in a purple mini skirt and elaborate top as they shared a drink with a guy in what looked like full body green paint, another in a brightly coloured spandex suit with a bright red R emblazoned on the chest whilst a small black ‘mask’ shielded his eyes
“Ahem!” Gwen loudly cleared her throat whilst playfully waving her arm in front of her cousin’s face “I think you’ll find there’s a much better looking green person right here, Dweeb! Unless that’s what you’re into!” Gwen giggled to which in response Ben, his eye twitching for a moment, broke into a smirk, Gwen realising his intentions too late before her ass suddenly hit the dirt as Ben unceremoniously dropped her
“Jackass!” Gwen snapped as Ben proceeded to lumber away, the Alien simply waving her off over his shoulder whilst stating he was getting a drink “you better get me one too!” she added as she picked herself up and dusted herself off “I swear he just chooses to forget that I only like to be dropped AFTER he dumps a load in me”
Patting down her ass to remove any remaining dirt from it Gwen decided to let Ben’s rudeness go and to enjoy herself, starting to move her body to the heavy beat of the music as she walked through the crowd, admiring the costumes most of the people were wearing despite it no longer being Halloween, the party being set up as a bellated event for those who couldn’t celebrate on the day
Gwen didn’t have to walk for long until she found what had to be her favourite costume at the party, catching sight of a tall silver haired woman from the back clad in what could only be considered as ‘peak slutty Witch’, her body clad in a skin tight robe/dress cut so short that the end of it hung off her hips showing a teasing view of her ass and pussy from behind as it was blatantly obvious that she was going commando as well as donning the trademark Witches hat
Licking her lips at the sight Gwen was more than eager to see what the Witch looked like from the front hoping her costume was just as revealing as it was from behind, the redhead sauntering up behind the silver haired woman to tap her on the shoulder “hey hot stuff, you look as slutty from the front as the ba…shit” Gwen started before trailing off as the silver haired woman turned around revealing herself to be none other than Charmcaster
“Ah…” Charmcaster returned, caught just as off guard as Gwen was, the silver haired woman raised her hands defensively “before you say anything…”
“Say what? That we’re going to stop you? I thought we were done with this shit! You know you’ve been quiet long enough that I actually thought you had quit” the redhead retorted, her hands starting to glow a subtle pink making Charmcaster raise her hands higher
“It’s my night off ok?!” the silver haired women exclaimed making Gwen pause “look I’m not up to anything, like you said I haven’t been up to anything for months, other than working on my Magic and I just heard about this party and decided to just have a night to myself, have a few drinks, have some fun, let loose you know?” she sighed as she used her hands to highlight her outfit “hell maybe get laid for the first time in god knows when” Charmcaster then admitted making Gwen raise an eyebrow as her hands slowly stopped glowing
“Seriously? The great evil Charmcaster is out partying like a regular person?” Gwen couldn’t help but scoff with a slight smirk
“Is that so hard to believe?”
“The last time I checked evil villainesses don’t ‘party’, and what do you mean ‘get laid for the first time in god knows when’? I assumed you just mind wiped a guy and had your way with him”
“Hey! I’m bad but that’s too far even for me!” Charmcaster protested before sighing “look I’m actually telling the truth here for once, all I want is one night to just unwind, let loose and have some fun that isn’t trying to take over the world, truce? Just for tonight? We can go back to throwing spells at each other whenever we see each other after this”
Eyeing the older woman suspiciously Gwen found herself actually considering her offer, like Charmcaster had stated she also hadn’t come here to fight and just wanted to party, enjoy the night and at some point get dicked down “just for tonight?” the redhead questioned before visibly relaxing “fine, deal, I really don’t feel like having a cat fight tonight…nice costume by the way”
“Oh, thanks” Charmcaster returned, blushing slightly as the compliment took her off guard “yours is…really hot too, you really grew up nice” she admitted as she rolled her eyes along Gwen’s body, her thin dress leaving literally nothing to the imagination as even in the dim light of the crowded party and the starlight above Gwen’s tits and pussy were still near perfectly visibly through the material of it
“You say that like I wasn’t obviously going to” Gwen smirked back, running her eyes along Charmcaster's body again and biting her lip as a small breeze lifted her robes enough to show off her bare pussy “wanna go grab a drink?”
At the other side of the crowd Ben was slowly marching his way back to where he assumed Gwen would still have been, a huge tankard of his drink in his right hand whilst he held a ‘tiny’ normal sized cup of Gwen’s drink between his left trigger finger and thumb, both drinks having been given to him for free as the barman had been so impressed with his ‘costume’, his eyes scanning the crowd that stood just below his chest height, eventually catching sight of his cousin near one of the speaker systems that had been set up dancing to the music alongside a few other girls, a lecherous grin growing as he took in their equally skimpy costumes and how each girl was practically flashing the crowd around them as they moved to the music's beat
His grin quickly fell however as he soon recognised the silver haired woman dancing extremely closer to Gwen, thoughts of Charmcaster somehow controlling Gwen’s mind or some kind of extortion filling his head as he proceeded to drop Gwen’s drink and outright down his before throwing the tankard away as he marched towards them, the crowd parting from his large sized until he reached the ‘dance area’
Before Charmcaster could notice his presence behind her Ben took hold of her via the back of her robe, lifting her off of the ground and turning her around to face him “and what do you think you’re doing?” he growled as Charmcaster raised her hands defensively to which Gwen spoke up
“Ben no! She’s cool! We’ve made a truce for the night!” the redhead exclaimed “put her the fuck down! People are staring!” she then hissed to which Ben realised that to everyone around them it looked like he was basically assaulting an innocent woman “just put her down and let’s go somewhere quieter”
Glaring at Charmcaster Ben then sighed and outright dropped her like he had done to Gwen before “fine, but this better be good” he grunted before lumbering off, leaving Gwen and Charmcaster to follow him and the redhead to do something she never thought she would ever do in apologising for his behaviour to the Witch
A few minutes later and a reasonable distance away from the party the trio now stood near a treeline at the edge of the field, Ben looking incredulously at both Gwen and Charmcaster after the redhead had explained what the silver haired woman had told her “seriously? A night off just to party and get laid? You honestly believe her?”
“Well she seems to be telling the truth and seriously, look at how she’s dressed” Gwen pointed out, waving her hand up and down in front of Charmcaster to point out her slutty attire “I mean come on, even from up there you can tell that she’s going commando!” she then added, going as far as to grab the base of Charmcaster’s robe and lift it to fully reveal her tight shaven cunt to Ben before the silver haired woman could react “she’s blatantly here to get some dick!”
“Hey! You could have just asked me to prove it! God you’re just as annoying as you were as a kid!” the Witch exclaimed “you don’t see me stripping you! You know what?” she then hissed before grabbing Gwen’s dress and tearing it down, exposing her bare painted tits to the cool night air “how do you like it?!”
To Charmcaster’s chagrin however Gwen barely reacted, simply raising an eyebrow as her ruined dress hung from her hips “oh no, my tits are out when I blatantly came here to get laid” she deadpanned “all you did was speed up the process for me and Ben”
“Damn it, can’t you like me have something for on…YOU AND HIM?!”
“Oh stop, are you honestly surprised?”
“But it’s…you two can’t…it’s not…no I’m not surprised” the Witch started before quickly giving up with a sigh “you two always did bicker like some old married couple so I guess it’s not that shocking”
“Damn straight, now that that little hissy fit is over what do you say we kill two birds with one stone?” Gwen then suggested as she shimmied the rest of her torn dress off of her body, leaving her completely bare save for her body paint before she looked back at Ben “I’m assuming you’re cool with this?”
“Well you two did make a truce” Ben responded, sounding a lot less suspicious of Charmcaster as he eyed her tight body, an action that would normally draw nothing but her rage but the look of approval and lust in the Alien’s eyes caused a deep heat to pool in her loins to the point that she took hold to the base of her robes and pulled it up to further expose her now glistening pussy to him
“Good boy” Gwen purred as she proceeded to kneel down in front of him, her hands working to open his pants as she looked back at Charmcaster “well? You want to prove that we have a truce? Get naked and get over here”
If Gwen had given her that instruction at any other time Charmcaster would have outright laughed in her face or worse but at that moment she found herself eagerly complying, stripping herself of her hat and robe until she was as naked as the redhead before moving to kneel beside her as Gwen worked Ben’s pants open
As Ben’s massive Alien cock sprung free both Gwen’s and Charmcaster’s eyes widened in sheer shock, having never been fucked by Ben as Frankenstrike Gwen was just as surprised and aroused as Charmcaster who herself had simply never seen a cock of such magnitude before “oh my god…” the Witch gasped as her eyes ran along the Alien’s fourteen inch monster, its girth being near akin to her thigh making her heart race, her cunt burn and her mouth water “how are we even going to take this?”
In response Gwen raised her index finger before poking Charmcaster just below her navel, both her finger and Charmcaster's lower abdomen suddenly glowing pink making the older woman gasp at the warm feeling it caused “you really think I’m not prepared for this? I’ve been taking his dick in near all of his Alien forms for years, there’s nothing a little elasticity and reinforcement Magic can’t solve” the redhead grinned as she then applied the Magic to her own abdomen “now less talky, more sucky” she then stated before leaning in to start to kiss, lick and suck along her side of Ben’s cock
“You heard the lady” Ben smirked as he proceeded to push Charmcaster’s head forward until her lips met her side of his manhood, the Witch glaring at him for a moment before quickly melting into the action, the taste of his cock making her mind swim as she was soon mirroring Gwen’s actions, both women moaning and humming with arousal as they soon had Ben’s cock glistening with their saliva “that’s it, good whores”
Moaning and giggling at his dirty talk Gwen then shifted herself so that she was under his cock, letting it rest on her face as she inhaled his musk, her pussy oozing with arousal as she ran her tongue along the length of his dick from balls to tip before she proceeded to tap her jaw with her glowing finger the same way she had her abdomen, making her jawline glow as she then proceeded to open her mouth and stick out her tongue
To Charmcaster's utter shock Gwen then proceeded to take Ben’s fist sized cock head into her hot slutty mouth, from the side width and girth of the head it should have been impossibly for Gwen to fit it into her mouth but with one show of Magic Gwen proved herself to be, at least in this way, Charmcaster’s better as her Spell allowed her mouth to open enough to take her cousin’s cock head and the first few inches of his dick into her needy mouth
“Holy shit…” Charmcaster gasped as Ben wrapped a large hand around the back of Gwen’s head to help coax her deeper and deeper onto his cock, Gwen giving the older the perfect ‘watch this bitch’ side eye as she relaxed her jaw and throat to the point that she began to easily deepthroat the Frankenstein Alien’s massive cock, her throat bulging in a way that shouldn’t have been natural as her lips finally met the base of Ben’s cock “HOLY FUCKING SHIT!”
Smirking around Ben’s cock Gwen then tapped his thigh to signal him to let her go allowing her to pull her throat off of his length “there” she beamed between pants for air “got him nice and lubed up for you, now let’s see just how much that tight little cunt of yours can take”
“Wait what?!” Charmcaster exclaimed before yelping as Ben suddenly wrapped his hand around her waist to lift her up with ease, the silver haired woman staring wide eyed as Ben then proud her to the tip of his cock, the girth of the head forcing her legs open as her heart pounded so hard it felt like it was about to escape her chest “hold on! Give me a minuuuOHMYGOOOODDDD!!!” she tried to stall him only for Ben to push her down all the way onto his dick, Gwen’s spell allowing her insides to stretch further than ever before “he’s…he’s…he’s…”
“Stretching your cunt? Filling your slutty little womb?” Gwen purred, biting her lip as she admired how Charmcaster’s groin bulged all the way up passed her navel “come on, if I can take a cock like this and bigger surely you can” she teased as she leaned in to run her tongue from Charmcaster’s clit up to her navel before giving Ben a lustful look “fuck this bitch up”
Grinning back down at his slut of a cousin Ben began to pump Charmcaster along his cock like she was a fleshlight, knocking the air from her lungs every time he brought her to the base of his cock turning her gasps and moans into breathless squeaks, her eyes wide and mouth slack as she struggled to form any kind of thought, the once proud Charmcaster reduced to nothing more than a fuck doll for her former enemy
And despite her pride and a little voice in the back of her mind speaking out against it she was loving every second of it
As Ben slammed her down on his cock again and his meat stretched out her womb again Charmcaster suddenly seized up with a breathless cry, her legs straightening and her toes flexing as her insides got even tighter around Ben’s cock “fuck look at her, cumming like a shameless whore on your dick” Gwen panted as she knelt beside Ben, looking up at him furiously pumping Charmcaster faster along his cock as she worked her own pussy “don’t pull out of her, give her fucking everything”
“I was planning on it!” Ben growled back through gritted teeth, his balls tightening and cock throbbing as he took hold of Charmcaster’s body with both hands to start hammering into her, putting Gwen’s Spell through its paces as he turned the Witch into a slutty ragdoll on his dick, pounding into her like he was trying to outright break her before suddenly stopping as he hit his limit, letting out a low groan of pleasure as he began to dump literal pints of thick cum directly into Charmcaster’s pussy and womb, making her stomach start to swell as her eyes rolled back in mind breaking bliss
Twitching and panting as Ben then slowly pulled out of her Charmcaster barely felt it as he then dropped her, letting her hit the ground hard as the last few streams of his load shot out over her body, leaving her a shivering mess as Gwen was quick to sit up on her knees to start licking his cock clean of their releases
“That was so fucking hot” she moaned as she laced Ben’s cock with loving lustful licks and kisses “now why don’t you take this fat cock and show her how you use a real whore?” she then purred, looking up at him with desire and worship in her eyes
Feeling nothing but a powerful blissful ache from the waist down Charmcaster could do nothing but watch as Ben then picked Gwen up and turned her over to impale her on his cock from behind, watching how the redhead’s stomach bulged like hers had and her face twisted into a mindless visage of sexual ecstasy
Years ago she hated the both of them, hell she was still supposed to hate them but at that moment she couldn’t bring herself to even utter the smallest fraction of dislike for cousins, now when her heart fluttered and her cunt ached for more, her body screaming for her to move and join in as she took in how Gwen took Ben’s brutal use of her body just as well if not better than she did
“Maybe this truce can last longer than a day…” she pondered to herself, curling her toes and biting her lip as she watched Gwen reach her orgasm within moments of Ben starting to rail into her womb “maybe for a few days at least…”
