The Twink-Vengers

[Twinkification, Muscle Growth]

[In this rendition of these characters, everyone is at least 18 years old.]

Peter knew the entire arena was composed of hard-light holograms and Starktech environmental-shaping nanobots, but his opponent, the Hulk, was very real. Peter felt the tingle behind his eyes--the unnerving flash that danger was on its way--and deftly backflipped to avoid a massive green fist plowing toward him.

“Man! That was freakin’ close!” Peter said as he swung out of the Hulk’s reach on webbing stuck to a nearby building. He knew the other Avengers were in the holographic chamber somewhere--but how could the freaking Avengers hide out in a simulation of a crumbling city in the middle of an earthquake?

Once again Peter felt the sense that he was in danger before he knew where it was, so he flattened himself to the ground as an arrow flew over head. In midair, several feet from him, the head of the arrow exploded into a cloud of moisture-freezing liquid nitrogen. Peter shivered as he realized that arrow had been aimed at his head. He glanced around, looking for the vantage point Hawkeye had fired it from.

“Uh, Mr. Stark,” Peter asked aloud, “how much of this is legitimate danger and how much is just, like, virtual?”

A flat square lit up in midair near Peter’s head. He could see Tony Stark’s face on the virtual display, albeit cloaked in his Iron Man armor. “Not to worry, buddy. There’s safety protocols in place all over this. The danger’s real, of course, but you won’t get killed in here. We can’t test your abilities if we can’t trigger that handy danger sense of yours, can we?”

Before Peter could react, he sensed something else coming his way. He leapt aside as a lightning bolt struck the place he’d been standing while he’d been listening to Tony--had Mr. Stark been purposely distracting him, he wondered?--but before his feet hit solid ground, what felt like a megaton force hit the ground behind him, and then again in front of him. In reality it was the mighty Thor crashing, full speed, into the bedrock, while the ½ ton Hulk slammed into the ground on the other side of him. The two had planned the attack, and the shockwave sent Peter spinning into the air.

He had to right himself--but first, he needed to figure out which was was up. Before any of that happened, he felt his danger sense kick in again. Purely on instinct, he shot webbing out blindly. It seemed like pure luck that he snagged Captain America’s shield in midair, shifting its trajectory away from him before grabbed hold on an overturned tank with just his fingers. His incredible abilities allowed him to cling to the tank, upside down and from one hand, until he could right himself.

“Okay, boys,” said Tony’s voice over what seemed like a loud-speaker. “End simulation.”

The environment discorporated into its most basic digital components before evaporating, leaving behind a featureless metal cube, the training arena Tony had installed in Avengers mansion. With the simulation over, Peter looked around at the Avengers surrounding him: the green goliath Hulk, the stunning Captain America, the godlike Thor, the incredible Iron Man and, sheathing an arrow and putting his bow behind his back, Hawkeye.

“You guys weren’t really trying to kill me or anything, were you?” Peter asked, chuckling to hide his insecurity. He really wasn’t sure.

Tony’s faceplate slid apart. He smiled. “Look, kid, during that little Red Skull caper you tagged along on, you got knocked directly into a cosmic cube. Those things are like the Infinity Gem’s little brothers, and you took one right in the back; plus, it discorporated. We don’t know where it went, or what that energy did to you.”

Peter shrugged as he adjusted his mask. “You don’t think it’d… turn me evil or anything, do you?” These men who were his teammates had taken him on with full intensity, like they were coming at a supervillain. It was hard to dial down his anxiety from the experience.

Hawkeye chuckled. “Oh, good god, how would we EVER deal with an evil Spider-Man?” he said, rolling his eyes.

Peter seethed at the comment but tried to ignore it.

“We just wanted to make sure it didn’t do any danger to you,” Captain America said. “We’ve seen a cosmic cube actually stun a Celestial. We’re lucky you didn’t end up a pile of ashes.”

“To be honest,” Tony said as he reviewed some virtual read-outs that lit up in the air in front of him, “I was kind of hoping we’d end up with a Cosmic Spidey. Have you punching planets or eating solar entities or something. Imagine what we could do with that kind of firepower wielded by a do-gooder like you?”

Peter cocked his head at the comment. “You call me a ‘puke kid’ like every single day, Mr. Stark. Also, ‘irresponsible punk,’ ‘typical Gen-Z’er…’ ‘18-year-old know-nothing’...”

Tony shrugged. “You can be all those things AND a do-gooder. I think that’s an adequate assessment of you. But in any case, your strength levels are all where they should be.”

“It’s too bad!” Thor roared as he thumped a massive fist against his chest. “I was hoping it might add a little brawn to you. I’m a little tired of this guy--” he thumbed at the Hulk, who growled, “and could truly use a new opponent in arm-wrestling, mud wrestling… all of the wrestlings!”

“It’s weird though, isn’t it?” Hawkeye said as he stood behind Peter and clapped him on his shoulders. “I’ve seen your punch dent concrete and smash brick, but you’re all skin and bones. You ever consider the code name Scrawny-Man? Maybe Scarecrow is up for grabs. Stilt-Man is already taken, so…” He chuckled. Peter wasn’t sure, but he seemed to flex his arms to punctuate his comment, flashing the beefy biceps his sleeveless uniform showed off.

“I mean, my name’s Spider-Man,” Peter said as he backed away. “You ever see a spider with, like, muscles? I think my build’s adequate, isn’t it?”

Tony’s armor disassembled and pulled aside. He walked toward the arena’s door. “Relax, kid. I’m going to review these readings and see if there’s anything we missed. You’re sidelined until further notice. We don’t want you going nuclear on a mission or anything.”

Hawkeye gave Peter a shove. “Here that little guy? Go play with your Nintendo Switch or something. Or I dunno, put on makeup, whatever ‘men’ your age do nowadays.”

Peter fumed, although he realized that his mask hid his facial expression. “Y’know, I think I actually have a decent build for being 18 years old…” he said, furious when a whine creeped into his voice.

“Yo, Banner,” Hawkeye said to the Hulk. “Maybe pump the little Spider over there with some gamma rays to beef him up? He looks like he’s wasting away to nothing.”

“Imagine that!” Thor exclaimed, pumping his huge fists in the air. “Imagine if we could double the little Spider-Man’s size. Imagine a brother-in-arms of that magnitude watching our backs!”

“Look, after you all pretty much tried to kill me,” Peter said, feeling his pulse quicken and his vision darkening, “you think you could lighten up a little bit? Nobody ever looks at you guys and thinks…”

Tony froze. “Holy shit. Energy just spiked. What the hell?” He spun around.

Peter continued: “...thinks you’re… too small… or… not manly enough…” He felt something building inside him, a force that gained intensity with every moment. Within moments he realized whatever was building inside him was beyond his control. His vision went completely black. For a moment he felt like he was floating through space, like he was everywhere, connected to everything. He almost lost himself in it. Then things came rushing back.

He felt… heavy. It was only uncomfortable for a moment. He blinked and looked around, trying to figure out who the little guys in front of him were.

“What… just happened…” said a small, thin guy with a huge bow slung over his back. The bow looked so big and heavy that he might topple over. He had short blonde hair and an angelic face, slender build, deeply carved abs shown off by his shirtlessness, and a pair of metallic purple short-shorts that accentuated a huge ass.” He took a few steps, looking like he was uncomfortable in his body. He seemed to have trouble getting his balance.

Nearby, another little blonde guy struggled to hold up Cap’s shield. He had armored blue gauntlets and boots, plus an armored codpiece. His slender, toned torso was wrapped in a tight, sleeveless t-shirt with the symbol of Cap’s shield on it. A thin mask covered a pretty face. He batted long eyelashes as he looked down at his body, confused, then examined his perky butt. He reached down and squeezed one of his hefty cheeks with a daydreamy look in his eyes.

Near Peter were another slender-but-cute gentleman with thin limbs and green skin next to little brunette struggling to hold a heavy winged helmet aloft.

“Odin’s beard, what… happened…” said a high-pitched, feminine voice as the little brunette pulled his helmet off and let it fall loudly to the ground. Other than tiny metallic shorts, the little guy just wore a leather harness. “Mjolnir!” he exclaimed as he held up a long, slinky whip. He gave it a gentle crack. Sparks glittered in the air. “What… happened…”

“Well,” said a dark-haired man in a red metallic thong, “it’s clear this… originated from Peter, considering… how we all… changed…” He had bright red metal gauntlets on each of his hands, plus red cybernetic boots, but the rest of his lithe body was nude. Like the other little men, his sleek body was well-toned but tiny, with deeply shredded abs but nearly no muscle mass except in the gluteal region. He turned around and gave his ass a jiggle, getting a dopey grin on his face when he shook it.

“Did I…” Peter began, but the baritone sound that escaped him shocked him back into silence. “Did I… do that?” Peter looked down at him. His body was HUGE--he was more muscular than Thor had been before (while not quite the mammoth that the Hulk had been). He was grateful his costume had grown with him. He was also grateful that it hadn’t grown all the way--it stretched a little more tightly over his brutish muscular body in such a seductive way. He flexed his arms, then looked down at his cock, unmistakably huge, rock hard and pointing up toward his 8-pack in his skin-tight costume.

“Does anyone else…” began the twink that used to be Cap, “feel a little… I dunno… woozy?” He stared at Peter’s bulge, transfixed. A dollop of drool formed at the edge of his mouth.

Twink-Hawkeye shook his head. “I feel like I’m… so horny I’m… drunk…”

Twink-Tony seemed to be tapping information into one of his gauntlets. “Massively reduced muscle-mass, elevated libido, dropping I.Q’s, while it seems Spider-Man has experienced the opposite…” He grinned widely. “And while I do want to get to the bottom of all this, I’m not exactly complaining about that.

Peter took a step forward, now towering over little Twink-Thor. “You want some arm-wrestling competition now?” he said, grabbing little Thor’s hand and forcing the god to the ground.

“Ouch!” Thor whined. “Stop! You’re hurting my… arm…”

“You want me to be a little more tender with you, Mr. Thunder God?” Peter growled. His confidence, his feeling of superiority, seemed to have taken over. He felt like he was out of the driver’s seat and something else was in control.

Cradling his hurt arm, Thor looked up at Peter with wide eyes. “The least you can do after man-handling me like that,” he said as he slowly stood up, “is allow me to test the strength of this new body of yours.” Little Thor reached out to caress the bulky quad shown off by Spider-Man’s skin-tight costume. Peter flexed the quad, bouncing it for Thor’s amazement, while Hulk, playing with his nipples as he cooed and purred, straddling Peter’s other quad.

“Tony, will this wear off?” said Cap with a dreamy look on his face as he stumbled toward the towering musclebeast Spider-Man had become.

“Yeah,” Tony said, licking his lips. “Yeah, I think it will. Yeah, it will. We just need to… ride it out…”

Hawkeye tossed his bow to the ground, then put both hands on the rock-hard meat in Spider-Man’s costume. “I call first ride,” he said, looking up at big muscular Spider-Man with a mischievous look on his face.
