Chapter Text
“Woah!” Another... graceful landing. Leave it to some reality bending freak to cheat and send the one and only GhostSpider to another reality. And now, thanks to him, she was laying face-first on the ground. Something about having the floor pulled straight from under you and being sent hurling into another world kind of makes you lose your footing.
“Great…” Wherever she landed, she at the very least hoped no one saw that. Aside from having a less than perfect landing, seeing how she landed face down, ass up, she would have formally went to the closest villain and ask for death at that point. Despite this, she couldn’t be asked to move just yet. Simply put, a fall like that fucking hurt! But soon, after probably a full minute of sitting there, the masked heroine groggily rose back to her feet. Now then, where was she?
Lets see, people in matching school uniforms, pretty trimmed lawn, massive building… She landed in front of a college. Her college. And everyone outside just had a great view of her ass for a solid minute. Gwen could only let out a long, annoyed sigh as her fist clenched at her side. “As soon as I get my hands on him, I-'' But before Gwen got to even finish her small declaration, she was soon cut off by another student. “Nice cosplay.” Suffice to say, it caught her off-guard. Of course GhostSpider wouldn’t… fall on her face in front of a random college like that. That would be ridiculous. And rather than hearing the chuckles of her peers, she was surprisingly met with mentions of cosplay. And the occasional chuckle. But that couldn't be avoided.
Then she heard something that caught her attention. As one of the students walked past her, he pointed out one “flaw” in her design. “Nice outfit but the hood’s the wrong color. It’s red. Not pink.” “It is not the wrong color!” she retorted. And more differences quickly popped up in their comments. The spider insignia being missing, the lines are the wrong shade, her ass was too small. One of which wasn’t quite a design flaw but all of this combined was definitely enough to prove she was in a different universe. If this world’s version of her was so different than where was she? Could the other Gwen be any help in getting her back to her world?
Gwen reached a hand towards a building, fully ready to zip up to the rooftop. If the other her was here, and she was anything like… well, her, then finding her should be easy. In her own world, it was 4 o’ clock. The exact hour she’d hang out with Mary Jane at the mall? Though would this world’s Mary even be alive? Would this Gwen still not have classes at 4? What if staying behind and searching the college was the better option? She wouldn’t need to decide on this, though, as her web-shooters were… pretty empty.
Guess she’s searching this area first. There was no harm in looking around. But the mask stayed on. She needed to find this world’s Gwen and if anyone saw two of them, that might be a little hard to explain. For now, she was just a normal cosplayer clad in the wrong colors. But first, to the dorms. The other Gwen had to be around somewhere so why not check there first.
She had to admit though, it felt weird walking around her campus in her GhostSpider outfit. But given the scenario, no one seemed to really care as much as they would in her own universe. It was almost surreal. A passing comment here and an awkward wave there, she soon found that the layout was a bit different than in her own world. Because of course it was. She was lost.
But other than... herself, there had to be something different about this universe. There was always something . Was it really just her suit?
Something that was quickly answered, as two tall women staring at a phone mentioned her name. Sort of. Immediately catching the masked spider’s attention, (it was her name after all) she listened in. Eavesdropping. “Gwen is so fucking hot.” one of them cried. They looked at the screen with lustful eyes. Clearly there was something juicy on there but were they talking about her? Er, other her? A girl was curious. So, in a sneaky manner, she walked behind the two, hoping to steal a glance at what they were seeing without being noticed. This was slightly difficult though as... Well, they were tall. While she was 5’7, these two stood at a larger 6’4 But she was somewhat able to see a portion of it.
But from what she could see, it looked like... Her. But far more bottom heavy and way more busty, fucking what had to be this world’s version of Doc Ock. So he’s a woman in this universe. Huh. But more importantly, is that her with a dick?? And why is she fucking Doc Ock?
Gwen watched in utter disbelief. After so many multiversal incidents, the thought of literally seeing another version of her was a novelty nearly lost on her. But watching a more busty. Futanari version of herself pinning a female Doc Ock and his- er, HER tentacles and fucking her into the ground was NOT something she would expect. But that was definitely her. They were definitely saying “Gwen” was hot. And those were definitely the sound of her grunting every time she thrusted down. From the looks of it, they were in a public place. What looked like Times Square with destruction around them. Was THIS what this world’s Gwen did when she fought crime? Were they lovers in this world? It might have been due to her knowing Doc as an overweight man but something about that thought nearly sickened her. Her fighting crime through sex was somehow slightly less upsetting. She hardly noticed in the moment that this world’s version of her didn’t use a mask.
Gwen took a step away from the two. And only then she noticed that both of the women had dicks as well. Given that the school uniform included a skirt… it was impossible to miss. “So that’s what’s different here…” Were all women in this world like this? Or was it a certain few?
Wait, if women have dicks here, then would some guys have… “Hey!” Shit! Was she thinking aloud? Looks like mumbling caught their attention. “You a fan?” asked one of the futa. “That’s Gwen’s old costume, right? That dingy home-made one that tore apart on its first day? You REALLY know your stuff!”
Dingy? She worked hard on this suit in her world...
__
The other girl chimed in. “Yeah, didn’t it just get ripped up whenever she got hard? She had to ask that stretchy guy to make her a new suit.” The two recounted the older videos of the futa Gwen’s triumphs. “That reminds me, I still have the videos. Seeing that cock just rip out of that outfit was just…” almost as if to emphasize her love for the sight, the woman’s dick twitched erratically, already at full mast as though somehow wanting to harden further.
“I heard it even ripped open even the stretchy guy’s suit.”
“You moron, that’s impossible!”
After a sharp smack to one of the girls’ rear, they looked back at their phone, presumably in search of the older video, as Gwen slowly backed away from them. Only to be stopped by something… soft. As though two pillows were resting behind her head.
“You know, it’s been a while since I’ve seen that outfit. Can’t say I’m not flattered” It was her own voice. The other her. “How about we skip the autograph and give you something real nice to remember today.” Was it weird, the other Gwen made her feel small... No. She had to focus. “Focus, girl. You are GhostSpider. People are counting on you in your own universe. ”
The costume-clad Gwen spoke up to try to tell her about the possible doom her own world could be facing but unfortunately, the other her was having none of it.
With a tender tease of her smaller, D-cup breasts, the Alternate Gwen pulled her ever closer, all the while forcing her to sink deeper between the soft twin pillows she found herself hitting against earlier. The Alternate Gwen was tall , completely towering over at a massive 8’1. Which meant those “pillows” were the large, back-breaking O cup breasts that version was forced to carry.
Gwen bit against her lip. And as she tried to focus, to tell the futa version of her that there is something horribly wrong happening, she was silenced by another hand reaching down. The other her had to bend forward just to find Gwen's quivering hole given their huge difference in height. But strangely, Gwen was okay with this. It was clear the other her didn't wear a bra. Just beneath the thin fabric of her flimsy button-down were her massive jugs. It was definitely distracting for the webcrawler to say the least.
But amidst all of this, the thing that left Gwen the most dumbfounded wasn't the other her's massive height or gargantuan tits. It was the fat, nearly forearm-thick cock that was hardening against her back. The dick of a true freak of nature. Even down to the ladder-esque piercings scaling down the length. The uniform's skirts truly did allow all the space futas need to let it all hang at any given moment. Gwen just wished this wasn't one of them... Gwen stammered. It was the best she could do with that thing constantly reminding her of its presence. Even with the suit separating it from her, Gwen could still feel every pulsing vein massaging against her.
"There's... I-" But the other her was quick to silence. "Shh. You don't have to say a thing. I already know what you want. Just relax." A simple whisperer. But one that nearly made Gwen melt into... well, herself. The other her's hands kneading and caressing her... something about her own hands doing it made it almost surreal. In a way she wasn't sure how else to explain. Teetering right on the edge of feeling familiar while also having it be someone else entirely. Those fingers knew exactly what to do, pressing through the suit’s fabric toy along the length of her slit. Even her little nub was given attention with slow circular motions.
All the while, that massive cock pushing against her was growing harder by the minute. Gwen soon stopped caring of the others watching. The other her sure didn’t care. From the moment she was groped by her other universe self, she could feel the eyes of everyone present staring. Taking attractive women, no matter the area, was expected of this version of Gwen. Even the girls from earlier had begun to film it all on their phones. It was a spectacle seeing their favoutie futanari crime fighter fuck someone into submission. Supervillain or not.
The other her’s hands moved to Gwen’s waist. The perfect handles to hoist the girl effortlessly off her feet. The other her was getting harder playing with the girl's body. And Gwen watched completely in awe as the already monstrous dick grew to even more absurd proportions. Gradually, the meaty appendage sprang to life. It oozed out a steady stream of precum, falling and crashing into the concrete ground with an audible BLOP.
Growing larger, heavier. Eventually, springing its way to 4 ft with enough girth to probably kill her if the other Gwen wasn't careful. Forget being as long as a limb. It was getting longer than her whole torso. Sure, Gwen saw it in the video from before. But up close, it looked gigantic. Larger than even the biggest sex toy she had back at home. Just that fat, bulbous crown was wider than both her fists. And what better place to sit her, than on top of the massive thing.
The other her dropped Gwen onto her dick, and under the weight of an entire person, it was surprisingly sturdy. Not even for one second did it buckle under the weight. The only movement came from it twitching and bobbing upwards.Gwen was completely in awe. For the first time today, she was speechless…
The other her guided Gwen’s gaze back to the curious crowd. “Look at all those adoring people. Let’s give them a good show?” The hulking dickgirl slowly sawed between Gwen’s thighs. Sure, they were nowhere near as thick as her counterpart’s, they were just enough to be the envy of some women back in her universe.
The other her moved Gwen back and forth, weightless as a ragdoll. And for every gentle thrust forward, Gwen could feel her counterpart’s heavy, overfilled balls plap against her legs from behind. Even though her attention was supposed to be on the people, the beefy shaft sawing between her legs sent her spider-sense into a frenzy.
“Ready?”
Gwen was soon lifted once again, this time, with the futa’s arms wrapping around her “fan’s” legs, hoisting them up and holding right above her head, where the other her’s fingers locked together for security. Gwen could hardly move. And the whole crowd could now see just how wet she had gotten. Or at the very least, the drenched stains courtesy of her other self.
Trapped to the futa Spider’s grasp, Gwen found herself descending right on top of the other her’s cock. Flexing and curving upward, it was the perfect position to slide right into her. If only... Gwen wasn’t already wearing anything. Instead, it poked at Gwen’s ass through her stretchy black pants. The women from earlier were right about the other her breaking through her suits. All it took was the other her holding Gwen in place and a quick thrust, and the bottom of her suit she worked so hard to make was torn through in seconds.
The alternate her’s cock was thicker than anything she felt before. Only 4 inches had made its way in but it was more than enough to make her howl. Gwen’s spider-sense screamed at her. But she was completely at the mercy of her alternate self. And as the hung futa pressed her further down onto that throbbing shaft, Gwen could do nothing but whimper and watch. Watch as inch by painful inch squeezed its way into a hole it was never designed for. Her stomach bulged. An obscene outline of the beefy tool. Now everyone could keep track of just how much was being stuffed in the costumed heroine.
Even with all the strength in the world, the horsedicked stud could easily just slam Gwen all the way down. But for some reason, she didn't. If her other’s hands weren’t pressed against the back of her head, Gwen would probably be able to at least glance behind her to see her own face grinning back at her. This world’s Gwen was loving every second of this!
But halfway down, the other her finally pushed Gwen the rest of the way. With a grunt and a forceful tug down, all 48 inches of futacock was stuffed inside her. All the way down to the fat, overfilled balls of hers. The studded piercings on that absurdly wide cock rubbed against her insides. Maybe the futa simply wanted to give the people what they wanted. Or maybe she just got tired of teasing. Whatever the reason, it turned Gwen’s sheepish whimpers into a full-on screaming moan.
For just a moment, the futa left her there. Impaled on a cock larger than any horse could even hope for. All while their enthralled audience gawked and stared at the bulge pressing against the “cosplayer’s” suit. It was a good thing Gwen wore a mask. The moment she felt that colossal meatslab pierce its way inside, her eyes started to roll back into her head. The only thing stopping her tongue from lolling out from her lips too was the mask making it impossible. Just one thrust, and she could feel her brain leave her body in an instant. But while the audience couldn’t see her already cock-drunk expression, they could see how the rest of her reacted. Like, for example, Gwen’s legs quivering in the futa’s grasp and how absolutely the once small wet patch between her legs had become a massive stain. She squirted harder than ever before. And to think it was all because of a fat-cocked futa version of her using her ass. And as if to show off just how wet the little fan had become, the other ripped a finger down the fabric covering Gwen's quim, letting everyone see how hard she was cumming from her cock.
The futa winced, biting down on her lip. But soon replaced this with a wicked grin to her number one fan. “Fuck, you’re tight… You’re even better than Black Cat.” Gwen panted, struggling just to catch her breath as her other self whispered in her ear. “So… fucking…” the other her reeled her hips back, and Gwen struggled to keep her moans back to a relatively quiet muffle. But of course, that didn’t last long. “Good!” The futa seemed to growl the last word as she drove her cock back into the costumed hero. It was more than enough to force out another trembling whimper.
And so it began. In slow yet forceful thrusts, the other her battered away at Gwen’s insides with each time sending the twin oversized jizztanks to slap against Gwen’s already leaking cunt soon after. But despite the loud cry of pleasure from before, Gwen was doing a surprising job keeping her moans contained. She was doing her best anyways... With every push inside of her, the heroine could feel her resolve slipping. Thrust... after thrust... after thrust. Soon, her lips began to part. Her alternate self prying away at Gwen’s will. She would just need a little push and… “ahhh~”
Looks like the other her found the push she needed.
The futanari other had since unhooked her hands, and with her arms still wrapped under Gwen’s legs, reached around to fondle and squeeze Gwen’s D cups through the suit. Just the extra boost her ‘number one fan’ needed to let her voice free. She toyed with them, lightly flicking her pierced nipples with a finger while the rest of her hand kneaded away at the supple mounds. A feat made all the easier with Gwen never wearing a bra under her suit.
The other’s hands rolled across Gwen’s tits. “Pierced too? Its like we’re twins.” As if to see what kind of piercing Gwen had, her other wrapped her thumb and index around her nip. Or more specifically, resting them on the small metal running through it. Though she never stopped thrusting or even losing power, the amazoness was surprisingly gentle. As though she were just giving more experimental touches to know what kind Gwen had. After, she carefully shifted her touch, rotating around the metal nubs with the delicacy of a thief cracking open a safe, back to the more fleshy nipple.
Underneath the mask, Gwen’s cheeks had become a rosy crimson.
The other her leaned forward once again, looking face-to-mask with her new toy. “My very first costume and the same piercings? You really are a big fan, huh?” She could still hear the wild moans coming from behind the mask. And as admittedly hot as it was seeing someone getting fucked senseless in her own mask, It was getting in the way. So why not remove it?
The other her yanked up Gwen’s mask, being sure to reveal just enough to see her cosplaying fan’s full lips. For just a second, Gwen panicked, before her lips were overtaken by her other self’s.
Before Gwen knew it, her others’ tongue invaded her mouth. And finally being on the receiving end, Miles was right. She was a good kisser... Even as she was stretched to lengths she didn’t think were possible, she had felt more at ease than she ever did with her actual boyfriend. Completely and utterly hers. Melting into the soft pillows behind her as her alternate self slammed into her ass. That little kiss was just the final thing needed to keep her in the moment.
For the next few minutes, the two seemed lost in the kiss. The futanari this world had come to love thrusting in the same patterned rhythm. To her most loyal fans, this was gentle compared to how she normally fucked. But as the two moaned into each others’ mouths with those gigantic basketball-sized testes slapping against her fan’s taint, it was welcomed all the same.
Eventually, even the crowd couldn't help but touch themselves. Futa, men, and women united in the urge to fuck themselves to the spectacle in front of them. By the time their kiss was over, the entire crowd had dedicated a single hand to touching themselves to the sight. Some in tune with the rhythm of their hero’s thrusts and others, much more wild. Most of the futas there had even taken the nearest person they could find and brought them to their knees to service. But fortunately, there was at least one of them still focused on recording the main attraction.
But Gwen hadn’t noticed. Her senses were solely focused on her other. Already missing the touch of her own lips on hers, her tongue lolled out. Eager. Waiting. Like an excitable dog that was oh so eager for more of its master’s affection. And granting her wish, the other her gave one final, albeit playful lick to Gwen’s lips. The other couldn’t see all of Gwen’s face but a dreamy sigh added to the mixture of moans was enough for her to know she loved it.
The other her pulled back down the mask, stating that it was hotter with it on. She mauled Gwen’s breasts, holding and squeezing onto them as she pulled the woman back into her thrusts with a moaned. “I’m close...”
The other her picked up the pace. Her once steady tempo changed to quick, rapid thrusts as the giantess blonde’s impossibly sized dick rammed into Gwen. Her eyes shut, and her nuts clenching, the futa grunted as she began to unload into… herself.
The cock-shaped bulge riding along Gwen’s torso soon became hidden as her stomach began to widen from jizz. Gradually inflating like a balloon as wave after wave of ultra thick jizz pumped inside of her. All while her other didn’t dare to stop moving. Thrusting like a madwoman in desperate need to milk more of her dick and dump as much as she could into the cosplayer as possible. If this was how she came after a few days, Gwen would have hated to see how she came after a week. Even the smallest rope was plentiful enough to be considered its own wave, with enough force to rival a firehose. In just a few seconds, she had already looked 8 months pregnant. But mixed with the constant pumping from the futa, it had some... unforeseen effects.
As the cum rocketed into her rapidly expanding gut, it had to wind up somewhere. And soon, a small portion of the futanari’s jizz found a way out through Gwen’s mouth. Nutsludge as thick as oatmeal coated the inside of her mask with the same unholy goop clogging her throat as well. She coughed, pushing out little by little… but further staining her mask in the process. Both taste and smell, the ultra-thick balljuice invaded her senses. She couldn't escape it. From the soggy remnants of it rolling along her tongue to the amount staining her mask and forcing her to breathe it in. She was choking on jizz, drowning in it. And the only thing she had to do was cough, and add more to the cage she found herself in.
But after a full minute of being a nonstop cumdump for the futa, the other freed Gwen and lifted her mask up to her nose. She wanted to taste Gwen one more time. To taste the cum that painted her insides of her mouth. Once they parted, the ropes of white from their tainted saliva bridged their lips together. Gwen was once again left a panting mess.The alternate her, though, seemed better than ever. She was like a machine! Even as the cum stopped rushing out of her and she finally stopped moving, she was still just as hard as the minute they started.
Finally, the futa lifted Gwen off of her, letting her watch as that massive cock slip out... Still hard. Still throbbing. And still yearning for more. A waterfall of thick, chunky white semen splattered down onto the floor below with much of it washing back onto the twitching fuckpillar.
Gwen’s spider-sense alerted her of something. Though at this point, she couldn’t be sure of exactly what. Then, as if the answer, her other pulled up the rest of her mask. And reacting quickly, almost on pure instinct, Gwen yanked it back down with a subtle, thin web. She would rather drown in the scene of cum than have an entire campus see her fucking herself. “I’m… I’m you, dummy.” she finally said to the larger futa in a slight whisper.
If things were the same here as it was in her own world, there aren’t many others with webs or access to that tech. And judging by her other’s expression it at the very least stunned her.
“We gave a good show. But let’s continue somewhere a little more private..”
____
On a rooftop, a still bloated and unmasked Gwen explained the situation. From the evil villain banishing her to another world, to how she wandered into her own campus. Her holes were still exposed and dripping with her other's cum. After all, with a pool's worth of cum pumped into her, it would probably take days to drain it all out. Her thighs had become drenched in a mix of her and... well, her cum. And until she could properly mourn her suit, she settled instead on a makeshift covering to hide from the world her needy pink pussy. As she talked, she looked out over the edge of the building, being able to observe this... hornier world from a fresh angle.“And that’s how I wound up here.”
Unfortunately, the other her didn’t seem to be listening. Instead, taking the time to slowly stroke her cock while pretending to listen. An absolute horndog through and through. She pulled Gwen to another spot on the roof and pushed her down onto the floor. Taller and more somehow more fit, the costumed Gwen was a mere ragdoll to her. “I’ll have to thank him someday.” Before Gwen could get back to her feet, her larger counterpart had already pounced, pinning her hands and arms to the floor with webbing far thicker than her own and lining the still twitching cocktip to her dripping but still covered twat. The most the already cum-swelled heroine could do was raise her lower body. Or in other words, lifting her plush, legging-clad ass.
Without another word, the futa slammed her hands on that plump ass and thrusted in, the flimsy webbing only serving as a target for the hung shestud as she rammed her length into the waiting, dripping hole.
Gwen was just a toy to her. And as that massive cock bullied her womb, stretching and reshaping her walls like a rod through putty, she could do nothing but take it. Every thrust was marked with a guttural grunt from her other. Ramming herself in with every ounce of strength as though she were trying to break her from the inside. Knowing it was herself taking her dick meant she didn’t need to take it easy. She didn’t need to hold back. But also… “I am so fucking hot…” Fucking horndog!
To anyone wandering closeby on the streets, they were bound to hear the two. Gwen’s howling cries made sure of it. She clutched onto the ground. Or at least, did the best she could with her fingers so firmly stuck in place.
But then the other her’s fingers stabbed into the ground beside her face. Her digits dragged and tore through the concrete like sand as if making up for what Gwen couldn’t do. The familiar softness of those gigantic O cups rested on the heroine’s back as she leaned forward against her. And the heavy balls beat against the back of her legs following every forceful push in.
After several more minutes of relentless pounding, the other her pressed Gwen’s head down onto the roof’s floor. Her balls gradually wearing out Gwen’s legs reached higher onto her thighs, tightening, getting ready to push one more load into the interdimensional variant.
And just like that, her other hilted inside while a rush of semen overfilled Gwen’s twat. A single spurt was all it took before the rest began to gush out past the already slight crevice. Before, she just looked pregnant. Now, she definitely was. Pregnant with… herself. That's not cheating, right? Miles wouldn’t suspect anything if the baby looked like her. The more her mind tried to focus enough to even think of an excuse to tell him, the more her stomach bloated jizz. It didn't take long before her suit began to tear apart. She was no longer the same size she was before. But she was surprised it took this long to rip. She didn’t even need to keep herself up with her legs now. Her belly became more than enough to keep her ass raised.
When her other was finally finished… she hadn’t gotten even the slightest bit soft. Gwen could still feel her throb and twitch. Ever eager. Ever the horndog.
“You and me are gonna be good friends.” the futa sighed. “So, ready for round three?”
_____
The next morning, Gwen woke up to the most bizarre dream. More than that time she worked with a literal spider version of Peter. It was her... fucking herself. Talk about surreal masturbation.
But the moment she dared to sit up, she realized her legs were still wobbly. Her tongue still tasted the salty spunk that stained her mask in her nightmare. And more importantly, and arguably the most noticeable, her stomach. Still bloated but nowhere near the absurd size it was before. Less wobbly too. Now she looked nearly 8 months pregnant. With twins. And as if to prove that, she could feel and see a foot pushing against the inside of her belly for just a split second. Already??
“What the-” Gwen felt something clogging her throat… and coughed bits of semen from the previous night.
It was all real. And looking around further, this wasn’t her home either... Laying on a velvet couch with a massive chandelier above her, this place didn't look like anywhere she lived before. It looked more akin to a living room of some mansion.
Somewhere not very far behind her, she could hear the sound of her own voice giving the warmest welcome she could think of. “You’re finally up. I was wondering when my new favorite fucktoy would wake up. Can’t wait to see our kids when the week’s over~” Gwen felt a shiver run through her as from behind her a hand reached down to feel her stomach, her hand , and ran across the smooth stretched skin kicking with life.
