Chapter 4
Erotica Sex Story: Chapter 4 - The Seedmakers are a race of genetically engineered males carefully selected for one thing only: breeding. They are hyper-virile beasts whose colossal muscles and endless stamina power their supermassive sexes into the wombs of the strongest, most fertile females of the Universe. This story follows the sexual exploits of one particular Seedmaker in his quest to unravel the mysteries behind his Creators... and his discovery of another equally fecund, equally powerful race of super females.

Hot wetness everywhere. Umidity surrounded him, made his skin burn. “Uuurhh!!” Roberto felt the groan escape his breast on its own. The ground beneath him shook. All sound died out for a while, with animals and birds fleeing his might.
The air was wet and hot, but also cool. It was the soothing type of air that was just perfect for every kind of person. Impossible to complain. «I ... I... » Still dizzy and disoriented, the Seedmaker remained on all fours, getting all those ... feelings ... and sensations ... of the new space around him! «Okay.» Little by little, his thoughts returned. «Let’s do it slowly. Inch by inch. Like easing myself into a female.»
He quite disliked himself for always thinking in such terms—sexual metaphors all—but he knew he was excused for the time being. Ever since he was born, sex was the only thing he knew. It was the only paradigm that was imbued in his very genes. How long it would take him to look past it? Who knew! What mattered to him, though, is that now he finally had a chance to find out!
The Seedmaker slowly stood up and scanned his surroundings. The first thing he noticed was ... green! Green everywhere! Green surrounding him, green going over his head, almost as intense as the darkness from his prison, but ... good. Lively. And not one bit asphyxiating.
“T- ... trees.” Unbeknownst to him, his lips were moving. “Trees. These are ... trees.”
He was surrounded by them. Trees. Indeed, trees. Trees everywhere. As lush and rich as his own body. Trees that, for the standards of a tree, were Seedmakers on their own: perfect and thick and infinitely rich. Trees the kind of which he would have to work hard to even just imagine: tall and wet and brimming with life. Trees that sweat. They perspired thickly through their trunks. A green aura of burning life emerged from these many trees—that’s how nutritious and potent they were!
After the green ... the yellow. And the red. And the purple. And the myriad of colors that came from the richest, juiciest fruits ever! The green of the trees was like the darkness of space: it was everywhere! Almost overwhelming! Yet the darkness didn’t stand alone: stars peppered it, sprinkled upon it like jewels on a lake of tar.
The same was for that green: green, green, overwhelming green, yes, but not a lonely green, not the only color there was. Like stars, the fruits of the trees shone like beacons of hope in the vast sea of emerald—but unlike the actual space, the stars and the dome both meant the same thing—life! Nutrition! Power!—unlike the opposing forces of the vacuum of actual space and the light of actual stars!
Green! So much green! And now yellow and red and purple and blue and... “Ah, fuck!” He took in another thing. Oh, heavens! It was so much! “Fuck!” It was so much it nearly overwhelmed him. “THE SMELL!!” He boomed, and then the ground quaked, the trees were bent away, and all the animals and birds in a hundred-mile radius fled.
He would be excused, of course: it was his first time feeling real nature and real smell! Even before his imprisonment, all the environments he fucked in were tightly controlled and mostly sterile. Even in the odd occasion when he was allowed to walk in the open air—with several restrictions so that lesser beings never caught a glimpse of him, lest they went mad with arousal and jealousy—most places were urban environments, and their gardens looked all artificial, and their plants were sterile and stiff. Fake, fake, all fake—just like his birth itself had been fake. Birth from tubes, not from wombs.
“Nature ... the nature...” Roberto stood still, stars twinkling in his eyes. Taking deep and powerful breaths, the muscular monster now pulled the tree’s crowns all towards him. The air could be seen by the naked away forming streams into his nostrils. The ground itself bent towards him. He was a godly stud in a real (albeit ideal) world, so reality itself bent towards his will, whether he intended it or not. “Smell ... the smells...” The god kept smelling and that beautiful world kept shocking him!
If not for his state of sheer ecstasy, like a blind man who suddenly regained sight and was immediately bombarded by all the colors of the spectrum at the fullest brightness of a birthing Universe, Roberto would have walked back and ... taken a lean against a tree ... supported himself on something, anything, for it was indeed too much, oh, “fuck!”, too much even for his mighty, genetically engineered superior senses.
He was a stud from heaven, and it was like he was suddenly overwhelmed by too many pussies! “So much ... just...” He panted. He gasped. The vegetation around him was pushed and pulled by his motions. “So fucking much!”
It was beyond the point trying to describe everything that he was feeling. If even himself tried to do it, using his reason to its fullest capacity, he would have spent fifty years just going through all the little new things he was experiencing: the thickness of the air, the two hundred major scents from all the fruits around him, then the fifty thousand smaller scents that made every single fruit unique, like prints on a man’s digit, then the five million micro scents of every single leaf, then the muskiness of the tree, the richness of their wood—and the eighty million different variations of said wood!—the moist wet dirtiness of the ground beneath his feet, the slimy touch of that rich, thick soil, the wetness...
Oh, the wetness! It was all wet in that environment! Wet like the pussy of a woman. And ... even more inviting? “Oh, this head.” After a literal hour of just ... taking in all those sensations and emotions ... Roberto felt stronger and more in control of his speech, enough to chuckle and smile and think aloud in longer sentences: “One day you will stop thinking in terms of sex. This is a promise.”
He opened his eyes. He looked around. Now and only now was he really opening his eyes and looking at his surroundings. The world was vast and intimidating and rich and disorienting, yes, but now ... it was a world he could actually inhabit. A place he could actually live in and interact with, not just ... a violent assault of images in his head. No longer just an unfathomable reality that his brain felt too constrained and shocked to grasp.
Now ... he raised one arm. He touched the air. And the fibers and strands of his muscles, he felt them, almost grew too strong and powerful for his black unitard. There was the sound of fibers stretching and something tearing up. At first, he thought it was his clothing, but then he realized that ... no. That was just his muscles. His impressive, massive muscles reacting naturally, with powerful and booming sounds, to a world that was open and free—no longer a dark and dry room made of plastic and metal and wires.
A real world that begets real growth of his muscles. “Hmm. Mrm!!” For a man who didn’t want to think of himself so much, all that Roberto felt in the next second of his senses was ... his full self! His body, through and through, and just how powerful the thing really was. “God. I’m so ... buff!” Roberto looked down, and before that sight all of nature, all of existence seemed to pale in comparison.
He was seven feet and six inches tall. Tall, he knew it. Much taller than any female and quite taller even than the average Seedmaker. Tall and powerful, yes, but always ... small. Not really tall. When all he had for comparison was the bodies of feeble women, his tallness didn’t mean much. Now, with his feet standing on real ground, his toes curling around real, mushy soil ... his muscles surrounded by real air and graced by the soothing scent of real leaves and real wood ... now...
Now he really got to understand how tall and powerful he really was!
“Heavens al- ... mighty!” The giant man boomed. The leaves fell from the trees more aplenty over his head. Fire erupted in him and his muscles swelled. For the first time, he actually felt the constraints of those tight-fitting clothes, and for the first time he felt out of his control that desire to just ... grab those clothes ... and... “Ooooh!!”
RIIIIPP!! One wouldn’t know it just by looking at it, but that unitard, that simple piece looking just like an elegant, smooth sweater, was actually stronger than the steel. It was woven from a special material which, when more refined, formed the base layers of interstellar ship hulls. To tear it would require special machinery able to crush smaller ships into boxes of scraps ... or a Seedmaker.
“Roooaaarr!!!” Steam burst from the monster’s nostrils. His face, those contorted, was the most handsome it’s been ... in forever! “Gooooods fuck!!” The monster tore the unitard off his torso like nothing, muscles booming and bulging, and the lights became almost blinding as his pinkish-white skin shone so naked, so freed onto that new air.
The place he had landed on was a deep forested area where light came in beautifully, but humbly. It was the dense, crowded dampness so typical of a heavy tropical forest—but without any of the discomfort that came with such a hostile environment. The lighting was dimmed, but no one could call it “dark.” It was a well-lit area. Despite the full coverage of leaves above one’s head, light seeped generously through billions of different crevices, shining stars in a sea of green, making the place cozy and inviting even for a complete stranger—hell, even for someone without one lick of survival skills.
The uncovering of Roberto’s chest, however, cast all this subtlety to the wind. As his super pectorals were revealed, the light bounced off of it a million times stronger, and for a brief moment it was like a new sun was shining on the ground, burning the trees and vaporizing the soil until nothing was left but steam and dust.
T’was merely an impression of course, but even as the light receded the Seedmaker shone like a thousand light bulbs. His mere presence seemed to carry a light of its own. Breathing harder, yet also more steadily, the giant bull god looked around once more, now with the biggest smile he ever had. “I’m such a god!!”
One second earlier, he was as humble as any man could be. He didn’t want to think of himself. He didn’t want to see himself as a sexual beast at all. Now... “God, fuck!” He looked down and marveled at his body. “Look at this rocking body!”
He was like a thin, feeble teenager who had been magically granted the Universe’s biggest, baddest body. With the unipiece still clinging to his arms, he raised his right arm and... FLEX!! He mightily flexed it, and a loud tearing sound came from the sleeves. The biceps ballooned enormously, and little by little the garment began to tear.
He raised his other arm. He gave it the mightiest of flexes. BOOOM!! The air and the trees, even the tiniest leaves all stopped moving. Nature itself took a pause from all Her labors to watch, in awe, that giant stallion flex and harden. Mother Nature, after all, was a woman—and no woman could resist a Seedmaker in heat.
Roberto enjoyed the pressure the clothes caused, fighting back against his swelling biceps. Grinning harder and making a slightly bigger effort, the god made his right biceps roar and then, after a lot of tearing and stretching... BOOOM!! A shockwave burst from the muscle as it tore completely through the sleeves. A hole was punched into the crown of trees above it. The biceps swelled almost too enormous even for Roberto’s enormous frame, and then it settled back into a fully proportional, but still gigantic swollenness. “Fuuuck!!” The ground shook as Roberto boomed, each burst of his voice coming like giants chanting from the depths of the deepest oceans.
Turning his gaze to the other arm, the monster raised it up, saw all his muscles boom and bust, and then ... he flexed it! “Oooorh, so good!!” He felt the blood and the power coursing through his hyper-thick veins, and then the muscles bulge and bulge and bulge while his biceps bulged the hardest, the biggest, the kings of all mighty muscles!
His pectorals swelled as well, tearing through the black rags that still clung to his skin. The biceps ballooned and ballooned and ballooned until, after a tense, roaring stretching, it burst violently free from the sleeve, BOOOM!!, causing almost a flash of light as it broke free. Such was its power that the sleeve was completely torn from Roberto’s arm, its long and sturdy wool come undone into four different stripes. As each stripe crashed on the ground, the soil sunk around it. WOOOMP! Each piece of rag sank several feet into the soil, and the four of them combined made a gentle crater where Roberto was standing—something barely noticeable for him as he only had eyes for his immense throbbing muscles.
BOOOOM!!! The release of his biceps had been so powerful that the tree suffered even harder than his unitard: the crown of leaves above him was blasted by the shockwave into a massive hole at least a dozen feet wide. Light poured into the grove now and Roberto’s body shone like a god. A literal god! A being of light contemplating his own immense power—and getting increasingly more aroused by what he saw.
“Fuck! Fuuck!!” The monster had no words. No words could ever hope to encompass that sheer power and potency he felt! His smile was pussy-melting, and for once he wished for some fresh pussy to be there, ready for him to bang and splay and fill with his seed.
The smells... sniff-sniff! Sniff! Sniff! The smells kind of pointed out to ... to...
Sniff-sniff! Sniff! Sniff!
Nevermind. The god needed no pussy. He had something much better. Something incomparably superior: himself!
Tearing the sleeve off the other arm, the beast stood beheld his two arms. Virile veins pumped and throbbed all over the massive trunks—arms literally thicker than most tree trunks he saw around himself. “Fucking ... pumped!” Bringing each of those arms in front of his chest, groping them and feeling their cheer hardness, their thoroughly virile and bullish power, the god also sensed the immenseness of his chest standing in the way.
The Seedmaker had the biggest, widest, most virile pair of tits any male of any species could ever hope to possess—and now these ultra-hard pectorals, literally thicker than the hulls of spaceships, stood in the way of his own adoration; a shining white body resplendescing with more muscles than the eyes could drink or the mind could count. “Fucking ... swollen!” Groping his monstrously large pectorals, the god felt a pain he could no longer ... oh, no longer ignore! “Roooaarr!!”
The bulge on his crotch grew extreme. Even at its most relaxed, yes, his penis was a beast of its own: it bulged and throbbed with peerless power, and its resting state made it still much longer, harder, and thicker than the penises of all equine species. The most virile animal stud in the Universe’s species most adept to animal husbandry would still come (far) shorter, with its dick fully hard, to Roberto’s totally flaccid prick—and now that prick was awakening and casting upon its owner the same kind of pain as his biceps were feeling when freeing themselves from their constraints. “Ooorh!! Ooorh, oooorhh!!!” Grunting and booming and roaring, the god undid all the rest of his clothes over his hips.
Boom! Boom! Bump!! Piece after piece of hundred-pound clothing cratered the ground as the god undressed, and then he groped powerfully his mega bulge with one hand, rubbing it and taming it, showing his cock just who was the Alpha dog there. “Hello, my breeder. Time to break free.”
He didn’t free it directly. No. He didn’t tear the “pants” or even flexed the penis or his thighs, no, no. Acting now purely on instinct, following a voice of heart he never even thought was possible—a heart not of his chest, but of his cock itself!—the monster raised his hands to his formidable body and then explored, with his heavy, sprawling palms, every inch of delicious bulging muscle he had in that picture-perfect torso.
Roberto was Manly. Manly! Manly!! He was every bit a Man as any Man could be. He was so raw his definitions blasted past mere Manhhood and reached those of Maleness itself. He wasn’t a Man. He was a fucking Male!! “Fuck yeah!” And this was shown so clearly, so humiliatingly in his powerful frame itself: Roberto had the widest, thickest, most delicious pecs anyone would ever dream of ... and just underneath it, in the sides of his mega torso, lay the biggest, fattest, hardest obliques any man could ever feel.
And he felt them, oh yeah, he did, groping and touching himself whilst his penis was filled with blood, pumping and throbbing and bulging and bulging, damn, bulging so aggressively from his pants it was insane to look at! The shape and thickness of his uncoiling snake was ... it was...!
Men would ejaculate just at the sight of it. Women, already creaming their pants with the mere scent of Roberto, would ejaculate as well, longer and harder than any man, and then collapse with exhaustion. Their bodies would have been sapped of strength and fiber due to the hardness of their ejaculations. They would collapse not even out of pleasure, but out of literal physical depletion.
Most women would never walk again. Their muscles would have been torn out and ripped at the mere sight of Roberto’s bulge. That’s how insanely virile it looked, and it was still only half awake.
Roberto boomed and puffed thicker clouds of steam as his hands groped his obliques and under-pecks. Meeting the obliques on his powerful sides, his traps complemented that triangle shape which was the apex of all virility; the pyramid of arousal that enslaved all female minds and engayed all male brains. “Fuck ... fuck ... fuck...” Groping his pecs and feeling their massive prominence over the rest of his muscles ... sliding his heavy, manly palms along the turgid edges of his humongous pecs ... getting a feel of just really how immense those man-tits were ... the monster felt aroused like with no female before.
Even his very first lays, at the very peak of his prime years, fell short of that incredible heat he was bringing himself just by the touch of his pectorals. His body was so manly that he himself wasn’t immune to it: for the first time in his life, Roberto felt the joy of gayness. “Holy ... fuck!” Roberto was turned homosexual by the mere contact of his palm with his mega-hard chest. “Fuuuck ... fuuuck...!!” The booms of his voice followed the deep, growling purrs of his cock. His entire genitals, protruding so obscenely from his pants, looked like a third whole legs cramped in there on his crotch.
The fabric stretched and stretched and ripped, showing the first tears of his mega-cocks unstoppable inflation. “Uuuurhh!!” The fire was only rising on Roberto’s groin. His hands still needed to graduate from the second most delicious set of muscles on his torso into the most delicious ones. The hardest ones. The most rippling, bulging ones. “What a god...!”
His fingers slid down to his nipples. He pinched and pulled them, then felt the turgid surface of his under-boobs. Based on the elevation alone, on how prominent those pecs were compared to the lower half of his torso, Roberto had a more bulging pair of tits than even the giant females he got to fuck—and those were nothing compared to the harder, stiffer, hotter muscles that laid below, in between those massive pectorals and his bulging, throbbing crotch.
Pair after pair, his palms slid down over his amazing rippling rock-hard abs. Roberto had the most bulging set of eight-pack any man could ever envy. Combined with the prominent bulges of his under muscles connecting the abdominals to the crotch, he almost looked like he had five whole pairs—though he personally thought that would be too much even for a Seedmaker, and that supreme male beauty lay in a sweet eight-pack bulging rippling abs. “Ooooh!!”
Fondling those muscles, he felt the semen bubble on his cock. The fabric ripped and tore, and parts of his steamy white cock began to show in the open air. The monster fondled and fumbled his immense muscles, feeling how hard they rippled and bulged and roared. His abs were harder than the hardest material known to the Universe. He had cruise ships hurled into them, only for the titanium-built crafts to crush and collapse under his unscathed, mighty muscles.
That was no joke: that’s literally how he was trained in his teenage years, when he wasn’t even a tenth as hard, as big, as bulging as he was now.
Sliding the tips of his fingers over those burning abs, Roberto gave them a slap, and a shockwave boomed from his hands. Lifting his palms again to his mega pecs, he gave his nipples a twist, and then... “OOOORHH!!”
TEAR!!BROOONK!! Like a mountain being lifted off the planet’s crust, his penis exploded freely from its containment. Blooorsh!! A lot happened in the same instant. Some pause would be needed to explain it all.
There was a BOOOM!! followed by a flash of fire followed by a trail and trench of soil being destroyed and blasted away in front of the mighty monster. The penis being released from its confined created a shockwave that burst forth and destroyed everything in its path. Three trunks were blasted as if by cannon balls. The splinters themselves were further blasted in the middle of the air. The nearby trees had their sides blasted away, and one by one they fell away from the trail, where a deep trench had been formed.
The magnificent cock sprung up in all its hardness, hitting the monster straight on his pecks, BLAAAAM!!!, then leaning back down in a less obscene, extreme angle.
Then, his monstrously large balls throbbed and the penis emitted a fat, thick, but lazy gush of cum. Blooorsh!! It was more cum to overfill the bellies of probably four hundred women, and it gushed and cratered on the ground in a huge pile and lake of white filth. His cum was steaming, as it always did, but the boiling itself was much harder, the bubbles rising and popping much faster despite all the thickness his material contained.
“Roooo-ooorh!! Roooar!!” The monster latched onto his mega penis with both hands, trying to tame it back. “Roooohh!! Roooorhh!!!” Low roars boomed from his throat. He was on the edge of his will, yet the sight of his booming, swelling pectorals, plus a glimpse of his glistening angelic abs was another spark to the atomic bomb fuse in his mind. “ROOOOAAAARR!!!”
A massive pile of cum streamed from his balls. His oversized cock head bloated outwards, doubled in size, and then expelled a formidable stream of semen, so powerful that it arched eight feet in front of the man, the entire arc probably being longer than fifteen feet.
It wasn’t an orgasm, however. When Roberto came, he really came! That lazy arc, that fat and horny ejaculation, oh, it didn’t rank even as a wet dream to the young god.
