A red-and-blue blur swung across a busy Manhattan street and landed on the rooftop of a six-story brownstone building. The figure was Peter Parker, aka the Amazing Spider-Man; and he had decided to take a lunch break in what was a particularly boring day.
He'd been swinging across town since dawn, and by noon, the only thing closer to a crime he had seen was a guy parking a Honda Civic in a spot reserved for people with special needs. Things had been very calm since the last week or so, when he fought the newest incarnation of the Sinister Six. Spidey sat down and took his lunch out of a paper bag, ready to enjoy it. For a brief moment, he thought Aunt May would frown at the idea of him taking a greasy cheeseburger and a can of Coke for breakfast, and he smiled to himself. The perks of being single, he thought.
He watched the street below him while eating. That was something he enjoyed to do. Just sit and enjoy the sounds and sights provided by the Big Apple. Dogs barking, birds chirping, cars honking and people screaming in terror.
Before he had a second to register the last part, his spider-sense flared and made his head pound as if a heavy metal drummer decided to cover Motorhead using his skull. People were screaming and running down the street. The squeal of tires after a sudden stop, police sirens blaring and more terrified voices echoed down the street; coming from Manhattan's southern piers. He couldn't see what was going on, but he was going to find out soon.
"Dammit" Peter muttered to himself. He didn't even got to taste his cheeseburger, and judging by the sudden madness going in the streets, he surely wouldn't have a chance for lunch in a good while. Cursing his luck, Spidey shot a webline and swung away to the pier.
It didn't took long before he found the source.
And then his jaw dropped.
A huge wooden ship of some sort, like a prehistoric version of the Titanic or an ocean liner, was moored in one of the piers in Southern Manhattan. And the worst part was that an army of blue and green naked 'Hulks' was coming out of it; attacking and well... having their way with every human being they came across. There were no other heroes in the scene, and the police was rapidly overwhelmed by the creatures; as their guns had the same effect on them as a B.B. gun firing at a tank. Then, he saw something that filled him with a terror he hadnt' experienced since fighting the Hulk for the first time or being face to face with Morlun.
A blonde policewoman was firing at a huge, male Hulk sporting a cat's tails and claws. The gamma felinoid lunged at the woman, teared her clothes apart and began mounting her from behind. However, before Spidey had a chance to swoop down and try to save her, the policewoman let out a shriek as her body bulked up with muscle and her pale skin turned a deep shade of green. In matter of seconds, the woman shred her uniform and became an eight-feet tall She-Hulk with a long, blonde mane of blonde curls and the largest breasts Peter had ever seen.
"BLUE SHULK WANT SPIDER!" A thunderous female voice boomed through the sky, and had Peter been slower or lacking his spider-sense, he would have been crushed by a wall of blue muscle and blonde hair that slammed against the side of the building he'd been climbing a second ago.
"Whoa! No kissing in the first date!" Spidey quipped as he landed on top of a streetlight. The musclebound blue woman let out a frustrated roar and pounded on her massive breasts in anger.
"BLUE SHULK WANT SPIDER! MAKE SPIDER BABIES!" The brute roared and jumped at Peter again.
"You want what?!" The webslinger leapt away, landing on another wall as the blue giantess slammed into the streetlight and bent it as if it were made of cheap plastic.
"BREED! BREED WITH SPIDER!" Then, she said something that shocked Spider-Man. "SPIDER LIKE BLUE SHULK BEFORE! Spider not remember Blue Shulk! Blue Shulk no longer puny Miss Marvel! BLUE SHULK BETTER NOW! STRONGER!"
"Waitasecond... C-Carol? Is that you?!"
"NO CAROL! BLUE SHULK NOW! AND BLUE SHULK HORNY!" The blue-skinned Shulk used her energy powers to impulse her body at neck-breaking speeds, successfully ramming Spidey before he had a chance to react. The two of them crashed inside the building, landing in a nicely decorated bedroom.
"C-Carol?! Stop, you have to...! You can't....!" Peter struggled in vain. The transformed Carol Danvers was too powerful for him, far beyond even the strength level of Venom or Rhino.
"NO CAROL! BLUE SHULK!" Then started tearing apart Spider-Man's costume with her powerful hands. She chuckled after seeing Peter's cock spring fully erect. "HURR HURR! SPIDER HARD ALREADY! SPIDER WANT FUCK!"
"Carol, no!" He grunted as Blue Shulk pinned him to the bed, squatted above him and grinded her hips against his rock-hard cock.
"NO CAROL! BLUE SHULK!"
"Nnnoo....! Urrrghhh!" Spider-Man started grunting as the gamma radiation in Blue Shulk's womanly juices started flowing and infecting his body.
Peter's skin darkened into an emerald hue as his flimsy blue and red costume was tore apart by the sudden and drastic increase in muscle mass. His intellect, memories and human self dwindled away, replaced by the primitive urges of his subconscious mind. His thickening hands clawed at Blue Shulk, grabbing her humongous tits and squeezing them until green gamma milk started pouring onto him. Blue Shulk moaned loudly and arched her back in an orgasmic haze.
The rush of gamma milk into Peter's body triggered a more advanced transformation: Two pairs of bumps formed along his sides, and soon the bumps lengthened and morphed into fully developed arms and hands; which instantly shot up, one pair caressing Shulk's wide ass and the other grabbing her by the hips. Peter's canine teeth lengthened into curved fangs, and four more arachnid eyes appeared over his forehead; but these were hidden under Pete's tattered mask.
Bristly black hair erupted throughout his body and his fingers gave way to three insectile claws.
The gamma-powered Man-Spider was born.
With a deafening, animalistic roar, the Man-Spider's grapefruit-sized testicles emptied their charge into Blue Shulk's womb. In seconds, the Blue Shulk's tight abdominal muscles distented into the beginnings of a pregnant belly; just as the blue giantess collapsed next to her lover.
"Spider... good...." She purred, caressing the Spider's muscular chest in a loving manner.
"Blue Shulk... better. Blue Shulk and Spider make strong babies."
"Yes. But Spider find more mates. Make more Spider-Hulks. Blue Shulk wait here."
The Spider's lips curved into a malevolent grin.
Despite his brain being reduced to a primitive caveman state, there was enough Peter Parker left on him to remember the location of women he knew. Black Cat, Jessica Drew, Silver Sable, Carly Cooper, Julia Carpenter, Anya Corazon, Betty Brant and most important of them all, Mary Jane Watson. All of them would become Shulks and bear him more offspring.
With a grunt, the Spider rose up and leapt away in search of more women for his harem, leaving the pregnant Blue Shulk basking in the destroyed bedroom. In the streets outside, the Hulk horde had doubled in numbers as the gamma monsters mated and infected all newyorkers in their path.
