Evolution's Own Reward

Victory never comes free.

To save all of humanity, he became a monster, giving up everything that made him the man he once was., and trading it for infinite limbs and a squishy, indestructible body. What was once a man had became a massive mass of writhing tentacles, somewhat gelatinous, very slimy, and unbelievably strong and durable.

Enough to defeat a thirty stories tall dinosaur with lightning breath, high speed regeneration and immense durability.

But the Hero was not hailed as such, in fact, his hideous, disgusting form was seen as even worse than the beast he had given up his humanity to defeat. The man who once was had enough control of himself still to flee, to rush to parts unknown, where none could see him, to hide his shame.

Though he had become a monster to save all of mankind, he was slowly but surely edging ever closer to becoming an enemy of humanity himself. He was turned to a creature that knew nothing but its most base impulses, a creature of unfiltered desire.

When he had a purpose, it was easy to just focus on that. To concentrate every part of his being to the singular thought of taking down the enemy.

But he had no more enemies left, not anymore, there was nothing that could stand before him that he could not beat one way or another, and even as he dug himself a hidey hole, deep beneath the woods that bordered a former logging town, he knew that if he didn't find something else to focus on, it would only be a matter of time before he started to go mad.

Loneliness was... a worse killer than anybody could ever expect.

He couldn't even bring himself to go deeper, he couldn't imagine bringing about his own death, and even when he mustered the courage, his body would not respond to his commands, deep down, he didn't want to die, and it was getting increasingly more difficult to deny his own desires.

He had never been the most pious or chaste of men.

So he hid. And he waited. And he concentrated on nothing more than simply... containing himself. With all his tentacles tightly coiled and retracted into his gelatinous core, he was only about the size of an SUV, so he could keep himself hidden, half-buried in the middle of a forest, which he hoped nobody would find him in.

...

It would take months before someone would... test his patience and his restraint.

A small group of people, in fact, would stumble upon his resting place.

Six women... college age by his guess, had found his resting place. He didn't have eyes, having evolved beyond the need for them and instead having perfect 360 perception from every part of his body, which meant they didn't know he had awakened and was watching them.

"See? Whadda, what did I," a bubbly looking blonde said, pointing at his mostly hidden body, "told yas I saw him swingin' this way, 'n we finally found'im!"

A black woman with tightly braided black cornrows scoffed. "You sure this him? Could be some," she bent forward, making her chest look positively huge as it strained her tube top, "like, molted skin or sum'," she pointed out, putting her hands on her hips.

A vaguely asian girl with long black hair straight down her back giggled. "Looks legit to me!" she said with a slightly stilted delivery, she was probably not speaking her first language.

"I don't know, this seems really dangerous..." one of the three woman who stayed back, far away from the mass of his body said, stepping back. The other two nodded.

"Cowards, bitches, whatever," the blonde countered. "Yer' either in on dis wiff us or," she swallowed a hiccup, "or y'all c'n fuck right offa my sight!"

"Fuck this and fuck you, Brittany, I'm out!"

"So am I!"

"And me!"

And with that, the three girls with actual brains turned around and left.

This left the product of ultra evolution alone with three young women, three college students if he was guessing right. He tried to focus on anything beside the fact that they were all quite light of clothing, tight tops, short shorts and skirts... lots of exposed skin, very showy, extremely hard to ignore.

He had to get them out of there. He was feeling desires that he didn't want to indulge, he was feeling the desire to attack, to crush them.

So he began to vibrate his form, producing sounds similar to a wild animal's growls, his tentacles starting to slip out and dancing threateningly in the air.

"Lookit!" the blonde, Brittany if he guessed right, called out. "Ey yo Tanishia check this shit out!"

The black girl stepped forward, she must've been Tanishia, and then bent at the waist, pushing her face almost against the vibrating tentacle that was threateningly moving back and forth, like the appendages of a wild animal about to strike. She even had the gall to poke at it. "Oh shit this is so disgusting and slimy!!" she called, laughing out loud. "Get a load of this, Kimmie!"

The final girl, presumably Kimmie, approached as well, straight up grabbing a tentacle and pulling it towards her, sniffing it. "Guh, this smells disgusting, smells like unwashed dick!"

"Shit, Brittany's favorite!" Tanishia laughed, scooping up a bunch of slime from one of the tentacles and throwing it at the blonde.

It hit Brittany in the chest. "Ough, ya biatch!" she called with a laugh. "Yer' gonna get me all slimy with this disgustin' freak's-"

He whipped his tentacles, letting more of them out, and then grabbed the blonde. If they weren't going to retreat, then he would make them understand just what kind of danger he represented.

His tentacles wrapped around her exposed stomach, biceps, thighs, ankles and wrists, he considered for a moment squeezing her neck a little as well, but with his incredible strength that could actually be dangerous.

"Shit shit shit!!" Tanishia stepped back. "What the fuck Brittany you said he wouldn't react!"

"Well he ain't done that any other time!!" cried out the caught and bound blonde, crying out. "Ahh it's so wet 'n disgustin'!"

The ultimate product of evolution ran his tentacles over her skin and pulled her up and above himself, spreading her limbs. He would scare them, scare them off and make sure no one would approach him again... he would have to do some things that were drastic, but it was important.

The only thing that drove him was the desire to protect humanity, even if it was from himself.

So he brought up multiple new tentacles and stuck them into her shorts, some up her legs, others down the waistline, and into her tight blouse, and then with a mighty pull and a shredding noise, he ripped all of her clothes off of her. The fact that she had no panty lines was enough to tell she wasn't wearing any underwear below, and her bra was a sports bra.

He rid her of that in moments too.

It left the blonde Brittany entirely naked, exposed and quite slick, her body covered all over in the slime that covered his tentacles.

"You think yer smart but yer not! Lemme go ya slick cunt!" cried out the blonde. "Yeah that's right I know yer jus' a softie, ain' gon' do shiet!"

Incensed by her disrespect, her taunting and her careless, moronic attitude, the ultimate evolved defender spread her legs and arms and held her firmly, pulling a strong tentacle around and placing it behind her... then rearing it back before whipping it forward at great speed, a deliciously wet crack resounding so far it caused distant birds to flee.

Or that might've been the earpiercing shriek, as shrill as shrill could be, that the bitchy blonde let out.

It was time to teach her a lesson, and the monster that was once a man wasn't going to let her off with just that, especially not after she had been an ingrate and a total bitch.

"Ngh! Asshole! Not even me daddy smack me in da bum!" the girl spoke between sobs.

He did it again, on the other cheek this time, and left a deep red welt on it as he did, provoking another scream from her, and as she screamed, he did it again, while at the same time, losing track of his tentacles as they began to swarm her body, wrapping around her chest, the ones around her thighs coiling further up and rubbing against her crotch.

One went around her neck, and over her mouth, muffling the next scream as he hit her again, then again and again, getting into a rhythm of strikes.

She tried to buck off of him, she shoved her hips forward, she struggled with her arms.

But he wasn't about to let her go. She was being punished after all! He ignored the reactions of her friends, he ignored their protests, he ignored their hands upon his body... and just hit her again.

But it was as he noticed one of his tentacles moving behind her, that he stopped himself. His blood ran cold, and he decided, enough was enough. She had marks all over her butt and the back of her thighs and surely she'd-

"Harder daddy~!"

The only thing he could think right then and there was... "What the actual fuck?!"

"Harder! Hit me harder daddy~♥!"

It was like a bucket of cold water. He refocused. He perceived what was happening under and around him. What he thought had been the other two protesting and trying to pry his limbs off their friend...

They had pulled their own clothes off. Tanishia wore only a high leg yellow thong, and Kimmie, not even that much. Slick with his slime, they had shiny skins, and he could really see the difference in skin tone between the three of them, appreciating the beauty of the three women, of humanity, which he had become a monster to protect and-

"Will you knock off the pity party already!?" the black skinned Tanishia said. "Grab me with'em big ol' limbs of yours an' shove'em up every hole!"

"'n keep spankin' me! I like it up the butt, and deepthroatin'~!" Brittany commented.

"Wh-What's going on!? Aren't you disgusted?! Terrified!? I'm a monster! I'm a slimy, weird, tentacle monster!"

"And I'm Japanese," Kimmie said, "duh!" she added.

"You're not even half ya cunt don't you go try pullin' the race card on me!" Tanishia interrupted.

Unprompted by his own thoughts, his body released many more tentacles, wrapping them all over the naked women, and then lifting them as well, promptly invading the women's assholes and pussies in moments. Tentacles which ended in openings, mouths, got to their tits as he lined them up.

In moments, he was latched on. A needle-like protrusion pushed into their nipples by their natural opening and then poured a potent stimulant into their milk ducts, immediately their breasts inflated, and within moments, he was starting to milk them like a cow's udders, taking great helpings of breast milk from them.

"Ohhh fuck yes, this is what I'm here for!"

"Nngh, hit me harder dahdeeh~!"

He couldn't help but be mortified by the word. Brittany was fucking kinky.

Kimmie meanwhile opened her mouth wide, sticking her tongue out, and his body reacted, pushing a huge tentacle into her mouth, immediately pushing her to the limit and then wasting no time in throatfucking her, pushing in and out, the slick slime it was covered with more than enough lubricant.

He proceeded to muffle Tanishia and Brittany's screams of pleasure with more tentacles as well, immediately starting to triple penetrate each of the girls all at once, all the way until he finally reached his limit, and exploded within them, filling them with massive amounts of sticky tentacle cum, pouring it up their holes, both above and below, before bringing them closer to his body.

Still inside them, he relaxed and let them rest, pulling his tentacles out of their mouths and reducing the movements of the ones on their pussies and assholes to just slow gyrations and rotations.

"You... why are you here, what-"

Brittany shuddered. "Ahh, we, we've been, studyin' ya, yer, biology, very interestin'! I won't bore ya with the details, but, yer the subject of our thesis 'n lab project," she said. "So dun' worry, 'n just keep, keep doin' that, ahhh, yeah, sorry 'bout callin' you daddy bee tee dubs," she said.

Tanishia giggled. "She's got issues," she said. "But you was damn fine," she added, almost patting one of his tentacles as it rolled over her flat stomach, leaving trails of slime on her shiny dark brown skin. "We're studying you aaall over!"

Finally, Kimmie relaxed. "Mhm! The other three, they'll be back!" she said. "We've determined, your mucus and your fluids are aphrodisiac in nature," she spoke. "Based on all the hentai I've watched, you're probably hyper fertile too!"

His drive was... calm. Content.

He didn't want to kill humanity... his body desired to reproduce with humans, and push them towards further evolution. Ever since he had taken the ultra evolution drug, he had thought he would be alone forever, but... perhaps the future was a little bit brighter than he thought.

"You don' mind being our project right?" asked Brittany.

"Heheh, I think he won't be mindin' none of this, 's long's we keep, heh, experimenting!" Tanishia said, with a slightly barking laugh.

Kimmie nodded. "I also want to test the limits of your body morphing capabilities, I have a lot of ideas to see which shapes you can imitate with your tentacles!" she said, reaching for her breasts, still swollen. "And we gotta test how long these last!"

Brittany leaned over and latched her mouth onto Kimmie's breast, drinking heavily of her milk. "Dang, this is some sweet stuff," she moaned. "I might just get addicted!"

Tanishia already had larger breasts than most, and with their new size, she could easily pop her own tit into her mouth. "Fuckin' a, delicious!"

Kimmie just moaned in response.

The monster that wanted to defend humanity at all costs, who had once been a man, could only wonder if perhaps his fate had just turned...
