A Spider's Tipping Point

Written in collaboration with Cross C

Peter returned home, bruised, tired and defeated.

His day had been pretty terrible. The one goal he had setting off was to just relieve himself, but all he’d managed to do was fail to catch a big titty jewel thief that was maybe-kinda into him. If it wasn’t for that new-homeless rumble he had to break up there may have been a chance, but he couldn’t just ignore that stuff. So many people still needed his help and so Spider-Man had failed to catch Black Cat.

“May! I’m home!”

“Peter!” She gasped from the other room, quickly shuffling around as Peter took his shoes off, “You’re back early! Th-this… I… well, I guess you get to see the surprise early!”

He had no idea what she was talking about, but for some reason his Peter-Tingle flared just the tiniest bit. Though these last few days it was hard to tell if it was that or just that a woman’s voice had entered his ears so his boner began to get hard.

Walking through the house towards his Aunt, Peter wondered what the surprise was. The day had been difficult enough already, and for all his whining and complaining he could honestly use a little bit of a nice surprise to perhaps raise his…

…oh…

“Yeah, I know right,” May chuckled, looking down at her body before showing off with a spin, “I didn’t want to come off as tasteless, but I ordered this ages ago before the blip, and I guess the post is finally starting to catch up with their back orders, haha.”

Sure, Halloween was coming up, but Peter had never dreamed of a reality where he’d walk in on his Aunt in a sexy Black Widow costume.

Form fitting leather hugged May far too tightly, looking like a second skin yet also a container for her slightly pudgy body. Her thick thighs were practically poured into the suit, rubbing against each other as Peter imagined the flesh underneath, especially looking up from there to the obvious camel toe that May had going on. He hadn’t the brain space to realise she was aiding in his visual groping, turning briefly to show off her tight bubble butt jiggle in the cosplay. Such intense chewing of leather, like it had been specifically designed to mould around her fat cheeks. His eyes continued to climb. Noticing the first irregularity in the fairly accurate outfit, which was May hadn’t zipped up the suit. Her naval pressed against the belt where the zipper had stopped, giving a full view access to her beautiful white skin against the contrasting black leather. All the way up to where a sight of full-V cleavage was proudly displayed. Tits that were begging for their life on the cliff of the suit’s edges, with one simple push they’d fall out of their proverbial cage and bounce around free. (The metaphor made no sense but when tits looked this juicy it didn’t matter.) The final part of the cosplay was a fairly accurate red curly wig, looking rather similar to that very first time Peter had seen Natasha Romanoff at the Stark Expo so many years ago.

Was the outfit tasteless? Peter didn’t care. He’d always had a massive crush on the Black Widow, something about her dark and mysterious allure made her so much more desirable. Many of his growing fantasies revolved around those spy’s curves, and though she’d become a coworker she’d never stopped being a part of his thoughts. If anything Nat had just increased in his desires after being around her so much.

All this to say, Peter’s erection was thumping in his pants.

“How is it?” May finally stopped the gauping silence, fiddling with one of her wrist gauntlets, “Since you worked with her, is it… you know, accurate at least?”

A swallow, a second pause, and yet Peter’s mouth was still far too dry to speak. Instead he nodded, unable to peel his eyes away from the amazing body in front of him. “Prfct…”

“That’s good,” She said with a smile, though that quickly changed when she got a good look at him, “Oh my god, are you okay? Peter you have bruises!” Her hands began shifting his face around to get a better look, yet he could only concentrate on the feeling of leather against his skin.

“M-mm… I mean, yeah.” He finally shook himself free of his own horny brain rot, “There was some cat-”

“You saved a cat from a tree?”

He shook his head, “No, a cat burglar lady, she… well, she got away because I had to break up another new-homeless brawl…” Peter sighed long and hard, partly due to a rough day, but also to try and deflate the iron in his trousers. “Sometimes… I can’t help but feel like I’m failing to keep the peace, and it’s hard trying to do too many things at once. I don’t know how Mr. Stark-”

Then his face hit cleavage.

“Peter, don’t you dare talk about yourself like that. Just because you have great power, it doesn’t mean you’re a God. You try your hardest, that’s all that matters, and if people out there don’t appreciate you it’s because they don’t deserve you.”

Few of those words actually entered his brain.

Spider-Man was far too focused on the Milf body in front of him. Her hug had pushed him far into her body, and he’d had no other alternative to wrap his hands around her waist in a similar fashion. Now his fingers were pressing against her addictive form.

What he also didn’t notice was the fact that May had doused her body in pheromones.

She’d gotten so many useful tools from her master, including the form fitting Black Widow suit from an actual Natasha. They’d disabled the weapons and traps, which meant it was just a fantasy defining accurate depiction of Peter’s childhood crush. The odourless pheromones had also been from her master, such potent things that had made her pussy gush in need (which had made getting into the tight suit easier) and would hopefully be the final nail in Peter’s need’s coffin. The urge to breed with his slutty aunt growing the more she kept him hugging her chest. Already she could feel his fingers growing bolder against her butt, and that oh-so-amazing erection twitching against her leg.

“Well, as long as you’re okay.” May smiled, faux trying to end the hug but finding her nephew’s grip too tight. He didn’t want the hug to end, but she still wanted to play along and tease him, “Peter? What’s wrong?”

So many things.

But right now, Peter’s crotch brain was finally winning against morality. So many days of being unable to cum were piling up and after the roughness of today this was making his thoughts turn off hard.

He wanted to get off.

He needed to get off.

This sexy body in front of him was built for pleasure. Huge tits, huge ass, wide hips for filling with cum, oh god did he want to do things to this body.

“Peter… you’re scaring me…” She whispered, trying to ‘struggle’ out of his grip again, but finding his spider strength too great.

Deeper his fingers began to massage her ass, more his nose began to smell her nape, and more his erection grew.

May was also finding it hard to keep the roleplay going, as she had to bite her lip to stop the moans and groans from leaking from her lips, “Peter… maybe you should help me with my costume?” She suggested, managing to peel his face from her tits long enough to grab her zipper and offer it to her nephew.

Finally taking his hands off of the plush rear, Peter did in fact take the request and grabbed the costume’s front metallic handle. A pulsing in both his brain and his cock at the possibilities this little thing provided.

For a second the zipper went up, as if Spider-Man had decided to finish her costume and not delve any further into debauchery.

Then it came crashing down, barging past her belt to unzip to the full amount possible.

The sudden motion made May’s tits finally bounce free of their leather confines. Her cleavage pressing tightly together before finally splashing out, hard puffy nipples swaying about in front of Peter as he finally got to see his Aunt up close in all her glory. Reason was almost completely gone from him, seeing her only as Black Widow or even Black Cat with their massive knockers free, but deep down he knew this was still May so he didn’t attack straight away.

May shuddered at the sudden nudity. She knew that she should probably cover her chest and do the whole ‘oh my god!’ act, but Peter looked so cute and hungry.

So instead, she decided to go for a different kind of act.

“Hmm, okay then,” Her voice sounded different to Peter. A little more confidence and sway to her usual motherly tone, especially when her hands cupped her chest seductively. “Well Spider-Man, are you finally going to finish your Avengers initiation?”

His eye was twitching almost as much as his erection. Oh how he’d wished to hear this from the original Natasha.

“You call yourself a ‘man’, yet can I be sure? Walking around, growing hard in that tight suit every time you see my body, and never taking the true Avengers initiative to grab my thick russian ass and fuck me with that spider strength of yours.”

May was too good at this. She could fade into the role like a damned chameleon, and she amazingly seemed to have guessed that her nephew had a ‘hard’ time around the sexy spy. But then she’d also been seeing a LOT of Peter’s reactions to her own body. His guilt finally getting shunted to the side by the true hunger in his eyes.

“So what’ll it be? How badly do you want to become an Avenger?”

Bouncing her tits, it was clear Mr Parker had completely lost himself to the fantasy. Lust had clouded his mind so May heard a quickly yiped ‘BADLY!” before her nephew’s mouth latched hard onto her nipple.

They tumbled over, May falling hard onto the couch as Peter hungrily bit her bouncing chest. Already prepping the other for suckle surgery with his ‘sticky fingers’ (as May called them) easily creating pleasurable electric effects up her body. Frantic suckles and licks all over her chest, like she was getting attacked by an actual bug, or maybe an octopus with how his hands seemed so nimble, all while he was nibbling her hard nipples to get the non-existent sap from inside.

Meanwhile, Peter was in spider-heaven.

Her pheromones were intoxicating, her body even more so. The object of his hidden lusts for so long, he’d always known his aunt was hot but this last week had made it painfully obvious. Her curves, her perfect skin, her youthful energy, Peter wanted to indulge in all of it. He was the hunter and she was his prey. Though his conscious mind was lying its balls off to say this was Natasha Romanoff, the rest of him was fine fucking May Parker just as much.

May tried to help, undoing her belt for the zipper to finally cross under her pantieless crotch, all while Peter focused on her lovely jubblies.

As soon as her crotch was exposed those sticky fingers got to work.

“AH! P-Peter!” She gasped out from the ferocious quickness of his strike, “L-like that! Oohh~ s-so good!” Her buttons were being pushed amazingly. Thanos had taken so much from their relationship, but her lovely fuckbuddy nephew had finally found out how good her body was. Deep down he was still hers, just like she was his. Not even space titans with power over reality could keep the true sexual compatibility of aunt and nephew apart.

Two in her pussy, and on in her ass. His fingers dove deep into her wet folds, sticking to the sides to create a solely unique experience of finger banging that only Spider-Man could perform. Even without experience in this reality the boy’s instincts were godlike, “YESSS!! OH GAWD PETEERRR~!!!”

Peter tingle. It tried to warn him about something, but what? Was it the fact he’d just made his aunt orgasm by his hand? Her bucking body and the pure glee on her face as her rocketing juices covered his skin and crotch. It was wrong but impossible to stop… or was it that his tingle knew he’d never want this to end?

As much as he’d kick himself later, Peter licked his hands of May’s juices. That tangy acidic glory tasted amazing on his tongue, and that beautiful lie that he’d made the Black Widow cum so easily was enough to make him penis pulse once more.

“G-good job so f-far, soldier…” the ‘Avenger’ smiled, her panting form looking so tantalising under the arachnid, “But I’m ready for the next level. Are you?”

Her fingers gently brushed against his cock. Already that was too much stimulation and temptation, the superhero couldn’t resist unzipping his jeans and letting his erection true airborne freedom. The fairly hefty weight landed right on top of her moist wetness, making her giggle in excitement at the sight of the overly red engorged member. It may not have been the size of a rhino like her master, but she knew their compatibility would leave her begging for more like he’d told her.

“Peter! This thing looks angry, are you masturbating enough?”

His eyebrow twitched at her, speaking through frustrated gritted teeth, “...maybe I’ve been busy recently.”

May could still see the barest form of resistance on his face, though it was being grinded out by taking his hardness and lining him up for one easy temptatious thrust, her widow voice returning to smoothly coo at him, “Well, I’d say you’re ready. Yet it’s not even my safe day, are you really going in without protection, Avenger?”

He knew he shouldn’t.

Knew at the very least they should be using a condom.

But… her warmth was literally on him. Leaking slit literally spitting its silky venom onto his **** cock.

Spider-Man knew he’d regret this, but when every fibre of your soul needs to orgasm it’s hard not to grab your aunt by the waist and thrust your way into her cunt. “MAY!”

“P-PETER!” She shrieked, a pulse of pure pleasure spiking into her as she took her nephew’s virginity. He hadn’t even yelled ‘Natasha’, he was so hot and hard for her, and his love felt so amazing and so deep in her needy pussy. “Y-you’re so big! Oh my god, oh fuck, you’re such an a-amazing man!” Fingers touched the slight outstretch of her stomach from where his head was poking against her inner walls, “N-now fuck me! Fuck me HARD!”

Sense: lost. Madness: achieved. Morality: meaningless. May’s pussy was the best thing in the universe, why was he fighting this for so long? It didn’t matter, nothing mattered but moving his hips back and doing it again.

“Mm!” She moaned again, “Th-that’s it! Go as fast as you like!”

She’d probably regret saying that in the morning.

The true speed and strength of someone that could do what a spider can wasn’t fully known, but when you combine that with a horny nineteen year old then you’ve got a recipe for true crotchal bliss.

Peter’s cock began picking up speed rapidly. Her stretched pussy desperately trying to hold on as the meaty mass inside her slammed up and down against her cervix as fast as it could. The feeling of **** cunt clenches against his grinding just encouraged him to keep humping. It was better than any wank he’d ever had. An aunt’s beautifully wet pussy and moaning mouth, he only wanted more of it.

He slammed so hard into her, it felt amazing, quakes of pleasure wracking her body with each thrust. Sensitive gushing pussy being bullied by spider menace. It was shifting her further up the couch his moves were so strong. Getting faster and faster until…

“M-MAY! I’M GoO-CUMMINGGG!”

Well, after so many days of not being able to climax he didn’t even manage to get through the warning. The dam broke relatively quickly and Peter Parker filled up May with a week’s worth of teenage semen.

“OHFUCKFUCKUFUCKKK!” Her body joined him quickly in orgasm, having already been feeling close before such a huge amount of womb ballooning jizz began to fill her up. Jets and jets of volcanic spider-sperm exploded out of him and into her hungry uterus. Slurping up all her nephew could give her until the liquid had nowhere to go but splashing out onto their couch. Staining it forever with their perfect love making juices. “PEETTEERRRR!!!!”

After what felt like two swimming pools of cum had exited his balls, Peter finally extracted himself from his aunt’s cunt. Watching as the purest white slop he’d ever seen began pouring out of her slit, practically bubbling out now he’d taken the cork out of the hole.

He knew he’d regret it, but then like a vulture over its meal he felt like he wanted more. And when that thick leather-clad ass rotated on the couch to wave at him in a doggy style position, he knew he’d never really have enough.

“Pretty good, but I think you still have more for me, don’t you Spider-Man?”

“Fuck yeah I do.”

It would take three rounds for them to move to May’s large bed, another seven rounds before either felt even close to satisfied, and another eight before they finally collapsed together in a sweaty pile many hours later.

As he drifted to sleep, Spider-Man thought about what had happened. Peter had gotten his first ever blowjob, titjob, rimjob, sex, anal, footjob, balls licked… too much to remember, all from his aunt that night. He knew it was wrong and gross and so many levels of fucked up, but it had felt too good. May had liked it, really liked it, so was it that bad?

…

Yeah. It was.

He had to make sure no one ever found out about what they did tonight.

Nor what they were probably going to do in the morning either.
