Friendly Neighborhood Cockfucking
Hipposagainstleopards

Notes: You told Spider-Gwen you'd go with her weird idea, you just didn't think it'd happen like this.

You were stuck in a web with your back caught on the sticky material while your clothes were currently missing. What wasn't however were your cock and balls portruding outwards as you looked up into the face of one Gwen Stacey. However, Spider-Gwen lacked her mask and what she had prodding at your own cocktip with was a large webshooter while her chest was opened up along with the groin.

“Sorry to take advantage of the situation~” She apologized even as she licked her lips in anticipation, “But I’ve always wanted to try this~” She slowly thrusted her hips, bumping the cocktips to prepare.

"Here?!" The blonde had quite the impressive member on her and honestly you were a bit worried at what she was about to do, hanging from a damn building. You really didn't want anybody to see this...interesting thing you had agreed to.

“The location isn’t my first pick, either.” Gwen admitted, “But this happy little accident has provided me with an opportunity, I can’t just pass it up, now can I~?”

"W-wait..." Your precum betrayed your feelings about it as your urethra leaked a bit out to lubricate the hole. How did you ever agree to let her use your cock as a pussy with that beast between her legs?

“You don’t seem to be against it~” Gwen teased, shivering at the feeling of the precum on her cockhead, “Besides, you’ll be getting a nice upgrade to your balls, thanks to this~” She referred to how much larger her nuts were in comparison.

“Though of course that’ll only last until you drain them of my cum~ Then they’ll be back to their, uh, usual size~”

Granted your own orbs were much smaller compared to those massive cumtanks but how could anyone compare to those? She had more prepared for unloading than a horse with the size of them!

"W-wait..." You pleaded as she continued to thrust her hips at your cockhead.

“Hold on…” Gwen ignored the plea, “Just… let me… make this a little easier…” She brought her hands to the cocktip she intended to penetrate, sticking her finger tips in and gently spreading the cumslit a little.

She just widened your urethra up so her own cockhead could try to push inside but with how engorged and huge her futahood was, it was still having a difficult time getting fully in the hole. You could only bite your lip as she kept pushing into your hole.

“Just readjust a little~” Gwen shifted her position so she could thrust more easily, “And…!” She slowly but surely pushed forward until her angry red cockhead popped in.

“There we go~!”

You could only let out a loud moan as you felt the beginning of her lengthy girth stretch your penile walls out and all you could focus on was the waves of intense pleasure now emanating from your groin as your balls bounced from the penetration.

“Oooooohh~!” Gwen moaned as she thrusted her hips, making her fat tits and the bowling ball she called her nuts bounce and slosh, “It feels even better than I imagined~! You’re a natural~!” She shuddered as the urethra seemed to try and suck her in, no doubt difficult thanks to the fat bulge of her cock.

Your own cock was now getting fairly engorged with the Spider heroine's meat and you could only try your best to not thrust forward in reflex at the odd method of penetrating your own shaft instead of an easier hole.

“I swear your cock was made for this~” Gwen bucked her hips, her cock spurting pre already, “It’s so slutty~” The walls adhered to her bulging cock, even as it stretched out the urethra, gripping and sucking her deeper, the pleasure causing her cumtanks to start making quiet glorping noises that gradually grew louder.

"This is..." Any further protest you made was cut off by a loud cry of pleasure as she kept going further into your cockpussy, the urethral tract feeling absolutely stuffed in a pleasant way as she just continued to pump her wide hips into you.

“Look at the bright side~” Gwen purred as she thrust deeper and deeper, “You get a nice show out of the deal~” She shook her fat udders as they bounced.

Those nice milkjugs would be a lot nicer to see if you were the one fucking her pussy or breasts instead of getting your member used as a cocksheath.

“Be honest~” Gwen teased, “You’ve stuck things down this cockpussy of yours, haven’t you~?”

"No, I haven't even fuck-" You tried to finish your sentence without a loud moan and failed.

“You can’t be serious,” Gwen grunted, her balls glorping rather loudly by now, “A cockpussy this slutty and you never put anything in it~? You never masturbated and had a hand up by your cockhead, rubbing it, maybe a finger brushes your slit and you just know you could push it in~?”

"No..." It was honestly embarassing to admit it but you hadn't tried anything nearly this weird until she had brought it up. You certainly didn't expect to be getting docked on a building however and the night breeze was certainly sending a chill through your body.

“Well, you’re sure to get addicted after this~” Gwen giggled, the widest part of her bulge having finally entered the slutty cockpussy, “I bet from now on, you won’t be able to get off with sticking something in your onahole of a cock~” She tickled the edge of the cumslit as she thrust in and out, going deeper each time as the walls tried to suck her more and more.

You couldn't believe how good it felt to have her girthy cock deep inside your urethral tract and getting further in. The blonde was going to keep putting more of it in your urethra and you couldn't exactly pull away with your body stuck and going into a faux-breeding mode.

“And I’m not talking a pencil or anything like that~” Gwen continued, “I mean something like a hairbrush or a broom handle~” She groaned as her partner’s urethral walls practically tried to milk her cum.

“Or better yet~” She leaned in close as she started doing hard, deep thrusts, “You’re going to have to buy a big, fat dildo to shove down your cockpussy~”

"Mngh...with the way you're going, it sounds like you'll get addicted..." You felt every single impact with your penile walls splitting further to make way for the meat currently using your shaft as a pussy.

Gwen really didn't seem like she was planning on making this the one-time thing that she promised.

"C-can you not tease me so much when you're so big?" You gasped out.

“Oh, I’m sure I am~” Gwen admitted gleefully, “I might have to go around doing this to everyone~ Maybe visit a gloryhole and fuck any unsuspecting cockpussy that pokes in~”

“And how can I stop teasing you when you’re being such a slutty cockpussy~?” Her nuts were glorping and gurgling very loudly, they’d probably be moving on their own at this point even if she wasn’t making them bounce with her thrusting.

"Good, you can not use min-AH!" The Spider heroine hilted herself in you and all you could do was cry out as you tried to react to the sudden flood of pleasure. It really got to you as your balls bounced up to smack hers as they grumbled, getting them to make even louder noises after they felt the orbs they would soon be filling up against them.

“Don’t worry, though~” Gwen grunted as she kept up the hard thrusting, her cowtits bouncing and clapping as they almost threatened to bounce up and smack her in the face, “I’ll always come back to my favorite cockpussy onahole~”

"I'd rather not-mmm~..." It was getting harder to act like you didn't want to keep getting your cock pounded like it was a cunt with a pair of wombs attached, that talk about balls getting pregnant had to be fake, right?

“Oh, like you’ll even be satisfied by anything less than my cock at this point~” Gwen mocked, “Tell you what, admit that your cock is just an onahole now and that your balls are nothing but cumdumps, and I’ll let you suck my tits~” She shook the massive, wobbly udders again for emphasis.

“I’ve seen the way you stare at them~”

"You'll just use my cock and balls exclusively if I do that.." You saw the way Gwen was looking at you now, the blonde wasn't thinking of anything but how much she loved fucking your urethra like a cockpussy that existed solely to milk her futahood.

She was going to break you with how her breasts jiggled with each passionate thrust.

“Nah, I’ll give you a break occasionally~” said Gwen, “Give you a chance to tighten back up a bit~” She was practically slam fucking her partner’s slutty urethra at this point, her balls glorping and burping louder than any of the other lewd noises going on, her enormous tits bouncing so hard they obscured her face a bit.

“And I can’t help but notice that you didn’t deny that you want to~”

"You can use my cock as a pussy and my balls as your cum containers if you use them like this every day~." What did you just say? Was she literally fucking your brains out with how hard she was ramning into your prostate with a wide grin?

It..did feel really good though...

“Ooooohh~!?” Gwen’s eyes crossed momentarily as her nuts clenched and spat out a gob of cum, “I just might have to take you up on that~” She moaned as she started thrusting even harder, her wrecking ball cumtanks swinging wildly as her tits came closer than ever to smacking her face.

Your prostate felt such an intense heat up against it that you couldn't even think about anything more than how her cum was trying to slide down into it after pushing aside the couple inches of penile walls in the way. The Spider heroine simply didn't care about your failure at even forming words and kept going with increasing force in your urethral tract.

“I’m just gonna keep you permanently stuck to a wall~” Gwen moaned, her voice occasionally muffled as her udders bounced up into her face, “You’re just my cumdump onahole now~ Your balls are gonna get fatter and fatter as I stuff them when I cum~ The only time they shrink is when my cum flows out of your gaped and ruined cockpussy~” She thrust deeper and deeper, her balls practically just letting out one, long burp at this point.

That was when you felt her flow of sperm slowly getting into your prostate and slipping into it as your vas deferens opened up to pump down your own reproductive tubing. That began to set you off as the condensed swimmers went into your epididymes and began to enter through those widening holes to fill up your balls with the blonde Spider heroine's cum.

"You're just going to keep me around for fucking my cock?!"

“Don’t act like you wouldn’t love it~” Gwen shot back, “From the moment I put it in, your slutty onahole of a cock has been desperately milking and sucking my shaft, pulling me deeper and deeper~” She started trying to wiggle her hips as she thrusted, almost like she was trying to really gape her partner’s cockpussy beyond recognition.

"You-oh~..." You were about to hit your own limit as your orbs slowly began to expand in their sack, only a small amount but enough to make a few veins on it swell up as the skin became tigher. It felt so warm in them that you could hardly think on anything but your own growing desire to ejaculate with how good her cock felt in your member.

“Uunngghh~” Gwen groaned, “I’m getting real close~!” Her thrusts were getting more erratic, her balls and tits doing slow, sudden bounces instead of the constant jiggling from before.

"W-wait, I'm-" Your own testicles were beginning to cling to your groin and began to pulse angrily at the foreign seed currently swelling them, making you realize you were almost ready to burst as well.

“Too~ late~!” Gwen sang deliriously as her balls clenched mightily, letting out the loudest, most obscene glorping burp yet as they dumped buckets of cum into the slutty cockpussy her shaft was stuck in.

Your prostate was burst into, right before your reproductive tubing, and then, your balls were utterly flooded by a wave of sperm and visibly bloated enough to get up onto your legs and reach your knees.

“Not done~! Not done~!” Gwen chanted as she kept thrusting as she came, her tits bouncing all over again, the obnoxious burp of her nuts practically drowning out all thought

"Ngh~..." Your family jewels could only keep swelling against your will and soon began to resemble pumpkins rather than testicles, the visibly swollen veins along your taut sack twitching in protest as you felt only intense warmth throughout your reproductive organs.

“And here’s the biggie~!” Gwen almost howled as she hilted herself in her partner’s shaft one last time as her cumtanks let out a sharp, almost deafening burp as one last massive cumshot spurted from her cocko deep into the cumdumps she had claimed.

Your loins practically swelled so much past your tip on her final burst that they sent her orbs slapping against her ass and now dwarfed your own lengthy shaft, reaching about the width of your torso. A web design began to form on the tightly packed sack containing your pleasantly aching testicles which rumbled with foreign sperm inside them.

“You made a lovely onahole~” Gwen panted as her balls relaxed from dumping such a huge load. She refrained from pulling her cock out just yet, which would prove to be something she might regret.

"Cumming~..." The words came almost as another soft moan out of your mouth as your overstuffed orbs began to cling to your groin, or at least hung closer, and frantically pulsed to send the vast deluge of cum back to its sender along with your own into the blonde.

“Wait, what?” Gwen was too slow to react, “Oooooooggghhh~!?” Her eyes crossed for real as she was assaulted by the sensation of a stream of cum forcing itself into her cumslit and down her urethra.

Your own penile walls were further stretched as the Spider heroine's urethra was forced to gape wider and wider to accomodate all of the sperm being forced into her now and this left you feeling even more drained than you had ever been.

“No, no, no, nonononono…!” Gwen babbled as she started frantically thrusting her hips again, making her tits and balls bounce once again as she desperately tried to send the cum back to its proper receptacle, “This isn’t how it’s supposed to go…! I’m not supposed to be the one with cumdump balls…!”

You couldn't even do anything but moan and let out lewd cries as everything Gwen put in your pair of orbs and interest went back into her family jewels, needless to say, the results of that on her cumtanks were quite the sight while your mind was overwhelmed with a wave of pure ecstacy.

“Ffffuuuuuuucccckkk~!” Gwen howled as her massive balls swelled even bigger, glorping yet again as they bulged and bloated with mixed seed, “They’re so heavy~!” Gwen’s face was an absolute ahegao as her udders continued to bounce from her thrusting

It almost didn't feel like it would ever end and yet, soon enough, you saw your balls returning back to normal while they dropped back down, still emblazoned with a web symbol while you tried to catch your breath.

“Cumdump balls~!” Gwen moaned and giggled, “I have cumdump balls~!” Her nuts had swollen to be true cumtanks in every sense of the word, absolutely massive, enough that she’d be forced to stand bow legged from their sheer size and weight. The sensation of all that baby batter in her nuts threatened to grind her mind into paste as it swirled and sloshed and churned even when she stood still. If she were to try and move, the amount of sloshing would have her cock drooling and spurting cum with every step while Gwen had the most moronic look on her face, grinning and giggling like a complete idiot who could only serve as a sextoy with her fat tits and ass, and especially her slutty cumtap of a cock and cumdump cumtanks.

"Well, this didn't turn out well for you after all..." You smirked as you saw the blonde Spider heroine go completely loopy thanks to your own orbs emptying into hers. You were about to relax when you felt your balls smack down...onto the webbing net and get firmly stuck to it as a wave of panic flowed through you. Gwen began to grin widely as she looked down at you, having lost any capability of cumming on your own again thanks to them being locked in place by her webs.

"W-wait a minute! Don't you dare-" You shouted as you could see the wheels turning in the futa cow's head.

“I think thish belongsh to you~” Gwen slurred as she slowly started thrusting her hips again, giving what she thought was a predatory grin but was actually just a look of a brain dead idiot drunk on pleasure, the sloshing of her cumdump nuts caused by her movements likely dooming her to be permanently fuckdrunk, incapable of anything other than getting her holes filled and her tits and cock milked, “Cockpusshy~!” Gwen the cow giggled.

“Cockpusshy~!”

"No! Pull out before you-" There was no way the blonde Spider heroine wasn't about to empty the entire contents of her balls into you if you let her keep thrusting. But unfortunately for you, your arms and legs were equally stuck to the webbing net and your urethra certainly didn't give any resistance to what she was doing, acting more like a pussy than your dickhole.

“Onahole~! Cumdump~!” Gwen babbled as she thrusted away like a monkey in heat, her eyes rolling in her head from the combined sensation of her inhumanly swollen balls churning, glorping and burping and her cock, still sensitive from cumming and being stretched to have cum forced down it, was gripped and sucked by the urethral walls of her slutty cockpussy toy, “Tiny balls get fat~! Tiny balls get fat~!” Whatever was left of Gwen’s brains seemed to drain right into her nuts as her cumtanks ballooned out even more with their loudest, most obscene burp yet as they prepared to clench already.

"Stop that before you absolutely ruin my balls!" You couldn't believe how roughly Gwen was fucking your shaft with her meat at this point and it felt regrettably good as you felt precum lubricating your shaft again. Her breasts bouncing even harder as the blonde Spider heroine went into a fucking frenzy and all you could do was watch and wait for the inevitable to happen. You could see them starting to cling to her groin again and let out a cry of protest as you knew what came next would be even more intense than before.

“Tiny balls get FFFAAAAAAAAATTT~!” Gwen screamed as her humongous balls clenched hard enough to dump all of their contents into her partner in one, massive cumshot, her cock bulging even wider from the sheer volume of cum she was spurting out, the glorpy, slutty cumtanks supplying this fire hose-like spray of cum letting loose a burp so loud it seemed to shake the air.

"AHN~!" You squealed as you felt an absolute deluge of the blonde Spider heroine's would-be offspring in a massive flood of seed punch through your prostate and down your vas deferens once again, now visibly bloating enough to look like anacondas next to your dick while the warmth just kept going deeper into you.

“Tiny balls getting fat~!” Gwen the idiot giggled as she continued to thrust away mindlessly, “Cumdump balls~!” Her cumtanks slowly but surely deflated, even if they’d still be massive compared to anyone else’s even when completely empty, and sent the cum mixture into their proper place for disposal.

"MNGH~..." You could only watch in pleasant horror as your previously emptied balls began to swell to sizes that would be inconceivable for a normal human and yet, they reached a good foot beyond your tip in height now and another foot past your feet. Still being stuck to the webbing net and filled with plenty of her pulsing warmth however as the web design stretched to fit your taut sack.

“Ehehehehehe~ Bouncy boobies~” Gwen was now basically entranced by the bouncing of her udders as she continued thrusting away like a moron, even as her balls continued to empty into that slutty cockpussy, “Bouncy boobies~ bouncy balls~ slutty titties~ slutty balls~”

You wondered if Gwen was ever going to get back to her normal self or just keep fucking your cock here like some mindless idiot, your pair audibly groaning in protest at how much foreign seed was packed inside them.

“Ehehehehehe~ Oooooooohh~” While there was no chance of Gwen’s mind recovering from this, she would, at least, stop thrusting as her balls finally dinged on ‘empty’.

“Good cockpussy~” She moaned as she shakily stepped back, slowly pulling out.

You couldn't even utter anything that wasn't a slutty moan as you looked down at the utterly massive cumtanks between your legs and now audibly sloshing with the blonde Spider heroine's cum inside. How exactly were you supposed to empty them now?

“Tiny balls got fat~” Gwen giggled as she stumbled down to all fours and crawled forward, staring at those cumdump balls and drooling.

Your orbs sounded like they groaned at Gwen completely losing her mind while you soon felt like you were about to pass out from all of the exertion and rough fucking she did to your cockpussy.

“Fat balls get kisses~” Gwen kept giggling as she pressed her lips to the stuffed cumtanks, giving them a slutty, sloppy kiss.

You hardly even realized the blonde Spider slut was now kissing your family jewels and yet, the completely filled sack and testes inside felt somewhat better. Your engorged veins on the taut skin began to slow their twitching while the insides roiled more gently.

Of course, Gwen didn’t stop at just one kiss, she instead peppered dozens upon the backed up nuts, making out with them like they were her lovers.

Your balls could only quiver even more as they sloshed in pleasure and the warm pulsing intensified in them right before you felt like your eyes were about to close.

That said, it shouldn’t be forgotten that Gwen was an idiot now, a complete and utter moron addicted to sex, so as she showered messy kisses onto those massive nuts, she continued to push forward, her lips and even her face slowly sinking into the sack. This had the lovely effect of forcing some cum back up the urethra to drool onto her fat ass that she was shaking whorishly as she made out with the huge nuts.

You could barely react as you felt the feeling of the massive amounts of seed in your nuts beginning to travel back upwards and moving through your reproductive tubing. Even if you had the sense to warn Gwen, she likely wouldn't care in the slightest in this state as she just keep suckling your sack with her lips.

Even with her newfound stupidity, Gwen didn’t miss the sensation of warm cum drooling onto the fatty globes of her ass, the feeling making her arch her back and pop out her ass in a very slutty way as she shook it even more enthusiastically.

“Hhmmmmmm~!” She hummed a moan into the stuffed testicles as her eyes rolled up into her head, her tongue spilling out of her mouth and turning her kissing into wet, slobbering slurps.

You knew you were about to cum yet again and this time, you had a feeling your family jewels would be absolutely unleashing a torrent. Soon enough, the blonde Spider slut made your cock throb and it began to fire out a geyser of cum, yours and hers into the night sky.

Gwen felt the sack of mixed cum clench and throb in orgasm, making her throw her arms around the immense balls and hug them tightly, pressing her face deeper still as she slobbered like a slut possessed.

You could only stay awake thanks to the sensation of your balls finally getting some release as they slowly emptied out onto the building and the blonde Spider slut, hopefully getting back to their original size soon.

The feeling of all that cum raining down on her had Gwen shuddering, her lewd tits and ass wobbling from the movements, her cock letting out one last spurt of cum that was still bigger than most people’s entire loads before her eyes rolled up into her head one last time as she passed out, essentially using the deflating cumdump balls as pillows. Getting all the rest she’d need before going another round fucking her new favorite cockpussy.

Though with her new sex addicted idiocy, she might also take the opportunity to get her fat tits and ass fucked and her cock milked, but that’s for another time~

That was the last thing you could even feel as the blonde Spider slut rested her head on your oversized family jewels and then proceeded to take a nap. Your own vision blacked out and you quickly found yourself left in a unconscious stupor like her as your still massive balls began to slosh pleasantly next to her head.
