Gems - Breeding License - Joy

The world had changed a lot in the ten years since Steven Quartz Universe saved the world from the Diamonds.

This statement wasn’t locked to Earth, but it certainly felt the strongest there. Humanity had grown, shifted, changed, and evolved around the second race of sentient beings joining their planet. Technology changed to manage the influx of aliens, both because of their influence and despite them. There were certainly struggles. Some were far less accepting of the newcomers, even outright rejecting them and calling them abominations. Time had softened issues slightly, but there was still tension in certain areas.

Perhaps the biggest question that arose from all of this that no one was expecting was the issue of love.

Gems were mostly gem-sexual, but having sentient beings around made humanity constantly wonder how they could get physical with them. Some gems even reciprocated these emotions, and many gem/human relationships had started up. It wasn’t uncommon to see a gem and a human kissing or holding hands openly in more progressive cities around the world.

Those that you’d expect often saw this as problematic. Gems were incapable of producing offspring, which some believed as ‘humanity erasure’. It had been laid out day one that this would be the case, but these issues kept rearing their heads. There was a whole TV show controversy about a dating show that tried to even pair up gems with humans. Along with multiple YouTube channels on both sides of the argument.

It wasn’t ideal on the gem side either. With their pseudo-immortality some saw human/gem relationships as ‘icky’. Plus, ever since Steven ceased gem production across the universe their own species wasn’t increasing either.

No new gems in ten years. It may not have been a threatening idea, but some gems still wanted to see their species grow.

How could these issues be resolved? Would gems and humans learn to live and love together properly?

Enter: Leo. The man who got a Lapis Lazuli pregnant.

The discovery had been an accident. They’d been dating a few months and had gotten physical one night after a party together.

It wasn’t uncommon for gems to transform their bodies to have the parts they’d need for a night, with the Internet it was pretty easy for them to study up on human female reproductive parts. Some other gems had set up useful guides on PornHub and other places on how best to generate genitalia to please your partner. Wetness generation, pleasure centers, tightness to not crush a penis. So when Lapis made herself a working womb it was just part of the process. And Leo cumming inside was just a fun extra step for both of them.

But the next morning she found that her body had transformed without her realising it.

Many human and gem doctors had analysed her and Leo for the next few weeks. It turned out to not be an issue with her, but with his swimmers. Carbon. Woven into Leo’s very DNA since birth. His grandfather had spent forty years in the deepest diamond mines on Earth, working tirelessly without even knowing that he was surrounded by a mix of terrestrial diamonds and extra terrestrial gem clusters, and being the only one to survive the great diamond mine collapse of 1964. The exposure over so many years had rewritten his grandfather’s genetic code, making his semen a slurry of gem and human genes.

Leo had that same genetic predisposition in his semen. The reason why human/gem babies weren’t a thing was the difference between biological and carbon life forms being incompatible. Even the one human/gem hybrid, Steven Universe, had only been made through a sacrifice of Rose Quartz.

There’s a long winded explanation on how it all works–with how Rose made human-like chromosomes with her gem that fused with Greg’s DNA, and how Leo’s sperm fuses a bit more directly hardening the light source egg into a separate source so even if his lover ever ‘poofed’ the egg would remain–but in the end it wasn’t important. After nine months his daughter was born, and Lapis was able to hold her in her arms, with no need to sacrifice her form to do so. She was almost entirely another Lapis gem with a bit of human mixed in. Leo could breed with gems, and that changed a lot of things.

‘The Universal Gem Breeding License’ felt heavy in his hands.

Twas a gift from the Diamonds. Blue, White, and Yellow Diamond all loved Steven Universe and the idea that Leo could create more like him, whilst also being an ethical way to grow new diamonds without any animals or fauna to perish, amazed them. But the problem was not every gem wanted to be bred, and Leo’s human lifespan was only so long. His sperm was ironically incompatible with human eggs, and his father/grandfather had already passed. So they decided to craft him the gift.

Made from an assembly of their powers, mostly White Diamond’s, the license was Leo’s last ditch resort to make sure all gems would comply with their wishes. A little bit of mental bending occurred when Leo showed the license, forming a new idea in the gem’s head to love the idea of bringing new life into the world.

Sure, they could have locked Leo away in a human/gem breeding farm in space, but by the time they had reached Leo he was already an Earth celebrity. Gems all over were already asking him to travel to them so they could experience the miracle of human child birth.

In the end, it was easier to sell the lie by keeping him free range. Traveling the world to breed with any and all gems that wanted it, then using the license to convince those ‘on the fence’.

Leo didn’t even know he had the power, just that he should flash it to gems when he needed to prove his credentials. And the Diamonds didn’t truly understand just how easy it would be to sway a gem’s mind with it, seeing as they were unwittingly the first to fall to their own creation.

The first night with the three diamonds had been a special one. How could you not love the idea of a giant woman?

After smiling at the gift and flashing the license to the Diamonds, all three felt a flush of heat spreading over their bodies, not realising they were all weak to the subtle mind bending. He’d been summoned to their collective throne room, yet they were all too eager to abandon those seats of power to display their leaky cunts for him. Leo didn’t even know he had the power in the card, but was very happy to be seduced by such tall women.

They shrunk down to about eight to nine feet tall each, just enough for Leo to still have a chance. Blue Diamond summoned a cloud bed and the three of them stripped down for their new master to breed them.

Yellow Diamond was first to feel Leo’s humanity spreading her out. Somehow being the most submissive of the three, Yellow took orders of how to act very seriously. She felt out of her depth emotionally and appreciated being told to place her hands behind her back while spreading her legs so Leo could have full access.

Despite her serious face, the cracks began to show almost immediately when the human began fingering her and sucking her tits at the same time. It was all so physical compared to the more spiritual connection between gems, but no less enjoyable. To Yellow, the act of shapeshifting nipples was perhaps silly, but the pleasure she felt as Leo suckled and played with them showed her how silly her own feelings were. Humans knew so much about carnal lusts she was quickly lost in his tempo.

White and Blue could only watch on with jealous lusts as Yellow’s moody face contorted in pleasure. Leo fucked her missionary, though still made her hold her own legs under the knee to spread her out for him. His head only reached as high as her chest but he still completely dominated the tall lemony thicket. Her light form was so sensitive after seeing the license, with her preformed womb aching in ways that had never happened to the Diamond Authority’s military commander before.

After pumping Yellow full of his seed, it was Blue Diamond’s turn next.

Though they were all made of light, his next conquest certainly seemed squishier than the last. Leo could almost imagine Blue Diamond as Lapis’ mother, she certainly looked and acted like one at least, which only made him more eager to smother her with kisses and caresses. The sheer heft of her chest as he fucked it, the sweet tasting lewdness of her tongue smothering his, all while she kept him close with passionate hugs. Then totally turning around to get fucked from behind, as Leo stood behind her to grab her huge azure ass and ram into her. She was certainly the wettest, spraying his crotch with copious amounts of her juice while her eyes leaked pure joyful tears.

And then there was White Diamond. She was the strongest, the one whose power coursed through the license, yet she couldn’t mentally twig that its powers controlled her desires. The ideas of breeding with this human just felt so natural to her that of course she’d push him to the bed and ride his cock. For eons she stood untouched and unparalleled, barely even interacting with other gems, yet here she was willingly stretching her pussy around the human’s sizable shaft. All the way until he painted her walls, well, white.

The only other thing Leo made sure to do with all the Diamonds, was rub his cum into their actual gems once the deed was done. He had no idea if it worked, and scientists had told him there may not be a causation to it, but his first Lapis girlfriend did it on the night they conceived so he kept doing it. A way to sort of ‘mark’ his girls by introducing their very source to his semen. Plus, they always looked so aroused once he started playing with their gems.

After his night with the Diamonds, Leo followed through with the request to become a world traveler.

With how far gems had spread throughout the countries, he needed to travel almost every day to meet up with all those who requested him. A blog was started up to show his progress. If you were to scroll through the website you’d see many pictures (as well as some locked behind his slightly saucier Patreon backers page) of Leo spending time with gems. A fan of Leo with too much time on their hands even made an interactable globe that you could click on to see which gems he’d done it with.

In Madagascar, an Orange Spodumene gem was curled around him on their shared hotel bed. A Cherry Quartz in Britain was happily treating him to a beer in one photo, then a photo of her dragging him to a bathroom, where the final image showed her disheveled and barely able to keep her eyes open.Two Lapis Lazulis living near the top of Everest, kissing him on either cheek with some questionable splatterings on their own faces. A Flint in Brazil had him on her shoulders. A Serpentine was grabbing him from behind. A Prehnite was clearly sucking him off under a table.

Culturally Leo’s quest had gone down very well. Anti-gem human sentiment was down, thanks to Leo being seen as ‘claiming’ humanity’s planet back. Those that were pro-gem couldn’t find fault either, as so many gems were supportive of each other with the pregnancy/gem cultivation, and even those that were a little suspicious found a new found perspective when looking at the license on the FAQ page.

A few years later Leo had just become part of the noise of the world.

Focus and news reports about him had subsided for more topical information, to the point that some gems visiting from other planets may not have heard of him. The overwhelming joy they felt when he flashed his license was beautiful. A human that could breed them was a truly special thing.

The only real question was when he was going to finally reach Beach City?

“His exact whereabouts are unknown… but he was last seen travelling west at an angle of two-hundred and six degrees–whilst still accommodating for roads and railways he’s travelling on–aaand as you can see from these photos from his blog! All of different gems with human semen on their gems, Leo is 100% certainly coming this way!” Peridot beamed, concluding her talk to the mostly empty barn by closing her extendable pointer. “Mm, probably.”

“That… sure was informative!” Bismuth awkwardly gave a thumbs up.

“So Leo’s coming back, huh?” asked Lapis, thrumming her fingers against her face that couldn’t hide her smile. “Well, he was a lot of fun the first time…”

“Wouldn’t have guessed, you really don’t speak about him a ton,” said Bismuth sarcastically, frowning as she crossed her hands under her bust. “What the hell even happened to your daughter, anyway?”

“She’s moved in with her girlfriend on the moon,” Lapis shrugged. “I only really got to be a proper mom for like… three months. After that she was just a full grown adult and could do what she liked.” She stretched out, standing up from the chair that Peridot had set out for her presentation. “Honestly, feels like Leo shouldn’t even be allowed to travel so slowly. How many gems does he even get through a year?”

“Approximately three hundred and twelve,” said Peridot, matter-of-factly. “And you’re right, Lapis. This number could drastically increase if Leo was placed on a proper breeding regime. Which I shall bring up with him, as well as several other sexual efficiency upgrades, once he finally reaches Beach City.”

Bismuth shrugged, “This is all still a crazy world to me, but if human/gem relations can happen then I guess I support it. You met him too, right Peridot? Why didn’t you get pregnant?”

“I wanted to! But Lapis took up all his time! All I got to do was sit on his face, then when it was my turn he got teleported away to impregnate Yellow Diamond! Again! Grgh! So! Un! Fair!” the green girl was kicking the air in pure unadulterated fury.

“Peridot seriously miss out. Best sex ever~” Lapis teased, much to Peridot’s seething rage. “Hey, at least I didn’t rub it in too much during the pregnancy.”

“You did. Often.” Peridot grimaced. “But so what if you’re Leo’s favourite? And who cares if he’s statistically more likely to breed you over me again? I have researched human mating rituals based on drawings from the Internet! Behold!”

Peridot quickly rushed over to a portion of the barn under the stairs covered in a tarp. A piece of wood that acted like a wall underneath the stairs, but with the addition of three round holes in it. Neither Bismuth or Lapis knew what they were looking at until Peridot snuck around the wall, made some shuffling sounds, before bringing her legs and naked ass out through the shortest hole.

“Human males use these devices known as ‘glory walls’ to select the female they wish to breed with at complete random! If we all get in this before Leo arrives then he is sure to only choose the cutest butt, which is mine, obviously.”

“Pfft, as if.” said Lapis.

Bismuth rubbed the back of her head, “Uhh, how is it gonna be anonymous if we’re all… you know… multicoloured?”

“...” said the rear of Peridot before letting out an angry, “GAHHH!!”

“Don’t worry. I’m actually a little colourblind.”

The new voice made Bismuth and Lapis quickly turn their heads. The sight of Leo placing down his knapsack on the floor while smiling made Lapis rush forwards, flying towards him to jump into his arms. “Leo! You really were coming this way!”

“Well, I couldn’t leave my second favourite Lapis all alone for long, could I?” Leo smirked, dancing around with the blue girl wrapped around his waist like she was as light as a feather.

Lapis smirked, “Like I said, put me up against your wife and let me PROVE I can be number one!”

“AHH! H-he’s here?!” Peridot squeaked, legs kicking violently around while struggling to escape her own trap hole. “Ahh! No! Let me go, infernal contraption!”

“How long are you here for?” asked Lapis, quickly whispering something in his ear.

“Uh, only a few minutes?” he responded, which only made Peridot shout and struggle louder.

“Alright Lapis, stop teasing Peridot. Hey, I’m Bismuth. We haven’t really met yet,” she reached over and shook his hand while Lapis continued to curl around him. “Heard plenty though. And sorry about Peridot, she’s excited you’re here.”

“Not to worry, I’m excited to try out my first glory wall!” said Leo, already undoing his belt. Peridot stopped struggling, though her legs couldn’t help but start dancing a little too. “Wanna get in there too, Lapis?”

“Sure!” she beamed, taking the hem of her azure dress and raising it above her head while walking. Her own uncovered ass quickly settled next to Peridot’s.

Which left only Bismuth. Leo had been stripping himself, and asked, “Did you wanna join too?”

“I’m good, thanks. Still trying to figure out how you got Lapis and Peridot to sing your praises so highly…” she replied slightly accusatorily.

Leo blinked for a moment before a lightbulb went off, “Ah! My credentials! Gems love to see this thing.” he said, quickly whipping out his sex license and showing it to Bismuth before she could tell him she didn’t need to see it.

Bismuth blinked, shocked at the legitimacy of the card as White Diamond’s magic coursed through her. “Wow. I guess you’re right, I didn’t really believe it until you showed me proof…” said Bismuth, looking deeper into the card for a moment before grinning widely. “So! You’re sort of like a Gem builder! We’re kind of similar in that way, I was the Crystal Gem’s blacksmith you see. Though I guess I used hammers and nails, while you use that big hammer to nail! Ha!”

“Haha, yeah it’s true,” laughed Leo.

Bismuth had become very touchy feely all of a sudden, using her big bulky body to keep an arm around the naked Leo, clearly becoming more enamoured with the idea of being bred. Her face had a blush, her body became hotter, and she couldn’t help but eye that huge human meat that rose from his legs.

“You know, maybe I was a bit too fast to judge. Getting to feel what it’s like to live as a human while growing a new Crystal Gem does have an appeal…”

“Would you stop flirting with him and just get in the glory wall already!” yelled Peridot.

“Yeah! We all want a turn, Bismuth!” Lapis agreed.

A part of her was tempted to just pick Leo up and run, but after a minute of mental deliberation Bismuth undid her apron-overalls and completed the trifecta. Leo was soon looking at green, blue, and grey peaches. All lined up for him to take his pick for his prick.

None of them would leave the barn again for three days.

“Man, Pearl. Did you see all the photos Peridot shared?”

“Yes, Amethyst. Obviously I’ve seen them.”

“That girl loves to suck cock,” said Amethyst, lounging on her couch while flicking through even more photos. “There’s so many of her with Leo’s dick making her throat bulge. Ohh! And this one of Bismuth lying on the floor giving him a titfuck! Wow, he filled her whole gem up with his cum, that’s cra~azy.”

Pearl was still pacing back and forth just outside the kitchen, glaring daggers at the purple gem, “Yes, THANK you, Amethyst.”

“What’s got your knickers in a turbine?” asked Amethyst, tossing her phone down before reaching over and eating a handful of cheese covered chips.

“Well, obviously you haven’t realised that Leo is coming here!” exclaimed Pearl, waving her hands around before returning to pacing. “He’s did… it with those gems in the barn then came to Beach City! Larimar, Crazy Lace Agate, that bizarre harem of Rose Quartzs, he even tracked down Jasper! Not to mention all those visits to the Diamonds-”

“Hahaha! The photos of Spinel wrapped around his body were super funny though!” laughed Amethyst.

“Amethyst! This is serious!” hissed Pearl, placing her hands on her thin face, “He’s clearly… saving us for last!”

“So what?”

“SO-!” Pearl caught herself, not really knowing what her issue was with being last. “Hm, I don’t know… I guess the anticipation is just getting to me.”

Amethyst jumped up from the couch to give her taller friend a hip hug, “Aww, does Pearl wanna get fucked?”

“I’m simply open to the idea of a new child!” admitted Pearl, flushing her skin slightly while nudging Amethyst off of her. “Steven hasn’t been around much… and as much as volunteering at the day care is nice, a part of me…”

“Wants to get porked by a huge human dick?” asked Amethyst, finishing the rest of her food in one oversized gulp.

“...how have you not grown out of these habits already?”

Amethyst shrugged, once more patting Pearl on the side reassuringly, “So you’re nervous, I was nervous on my first time too!”

Pearl blinked in shock, “Y-you?!”

“Not with Leo, no. But I have had sex with a human. Quite a few humans, not gonna lie.” said Amethyst, rubbing the area around her crotch with a smirk. “The feeling of them shooting their stuff all up inside me feels super weird, haha! But, also, if you shapeshift a few human clits it feels so fucking good.”

“I see…” nodded Pearl, “Sh-shapeshifting multiple clitoris’… does sound…”

“Oh BIG time great, Pearlie! Everyone always tries to match a vagina one-to-one, but if you put a clit right above your cervix then get a big dick to hit it juuust right, you… what?”

Pearl had been giving her a bit of a proud smile and had caught Amethyst off guard, “Even after all this time I suppose I’m happy you can still surprise me sometimes.”

“Haha, thanks.” Amethyst beamed, “But let’s stop with the mushy stuff, Pearl. I already called and asked Leo to come around today so you better be ready to get down and dirty with me. Hey, where’s Garnet by the way?”

“W-w-w-w-wHAT?!”

Garnet returned a few hours later.

While Pearl and Amethyst had greeted Leo in the main Beach House, since it was now Greg’s abode they’d quickly moved the fun to Pearl’s room. The eternally flowing water baths was a beautiful place to clean oneself while soiling the space that Pearl used to keep so tidy.

By this point, both of her old teammates were well past seeded. Garnet had entered Pearl’s room in only a towel wrapped around her waist, keeping a watchful eye on the trio for a little while before making her presence known. She’d certainly never seen Pearl so hungry. Her switch had flipped a while ago, and was just so happy to wrap her limbs around the human providing her so much pleasure. Amethyst obviously also enjoyed herself, and Garnet could tell that below the veneer of being ‘too cool’ she was also loving the attention Leo could provide. Shoving her violet tits violently into his face while he fucked Pearl. Or transforming her body to look like a supermodel’s only to be forced out of it by how hard Leo rammed into her from behind.

When Garnet did appear, the two were panting and exhausted. Perhaps even close to poofing before their teammate stepped in.

“Garnet!” they gasped, happy to see her.

“Greetings.” She nodded at them, keeping her face stoic as she turned to the human, “Hello, Leo.”

“Nice to finally meet you,” he nodded. Arms on the side of the pool he was in. The gem breeder part of him was big enough to float around by itself like a little meat ship, even if it was leaking. “I was worried you weren’t going to show.”

Garnet slowly brought herself to the pool, elegantly gliding in to sit next to him. Eyes always hidden by her sunglasses, “I have been around. I find waiting my turn easier when I’m not bombarded with stimuli.”

“Oh? It’s your turn?” Leo smirked, “Sure you don’t need to see my credentials?”

“I have already seen it,” she replied calmly, slowly removing her towel to show off her fully naked body in all its glory. The mix of strength and softness made even the well experienced Leo’s breath catch in his throat. “I saw a future in which you showed me your license, and when I did there was no other timeline I wished to aim for greater than this one.”

He was almost too enamoured by Garnet’s body to respond. That magenta skin with dark violet areola jiggling around on her perfect tits, with hips wider than his shoulders, and a pussy clearly excited even while she had just risen out of the bath. “Y-yeah? What makes this future special?”

“For this is the timeline where we three manage to get you to settle down with us,” she replied calmly, sinking to her knees to immediately start licking his risen member. Her violet tongue was long and eager, and it instantly made Leo moan while the other two reacted to the news.

“Woah! Really?!” Amethyst gasped, “You’re gonna stay with us, Leo?!”

“I mean… sounds it…” he moaned, hand in Garnet’s afro as she hungrily started bobbing on his dick.

Pearl clapped as well, “That’s wonderful! Don’t worry, we can make space for you! And your wife! There’s plenty of space on the beach for a second Beach House and-!”

“Girls. He only stays if we all lick him now.”

Amethyst and Pearl looked at each other for a second then dove down between his legs.

The three original Crystal Gems that saved the world with Steven. All of them sharing and licking Leo’s dick like their lives depended on it.

They looked at him with such adoration and hunger. Sharing in the goal to pleasure him with their tongues, kissing and sucking his sensitive skin as he groaned on the side of the pool. Amethyst grew an extra long tongue, Pearl just wanted to focus on his bulging balls, and Garnet just kept bobbing firmly on his cock all the way until he let loose in her mouth. Getting to see the faces of the heroes covered in his sperm was very erotic, watching them kiss and lick each other to clean, especially as he got to rub it into Pearl’s forehead gem at the same time. (She also seemingly pocketed a sample of it for her own collection, much to his amusement).

Once they were done with the bj, Leo took great enjoyment in finally grabbing Garnet with the goal to thrust into her as hard as he could. But she blocked him with her gauntlet just as he was lining himself up.

“Do you promise to stay?” she asked.

“Blackmailing me with your pussy, eh?” he panted, really wanting to fuck her especially when she smirked with those big puffy lips. “Fine. I promise.”

Garnet hummed, grabbing onto his cock quickly and pulling him into her cunt. They basked in each other’s glory, pleasure bubbling up from both of them as he fit inside her wet boiling slit perfectly.

It didn’t matter that she was married to herself. Garnet loved both sides of herself, and the feeling of getting fucked hard by Leo. Nothing about her was lying to herself about this fact, she was just a fusion who had the same desires as everyone else. Only difference was she was more likely to give twins.

He grabbed her huge nipples, kissed her luscious lips, and fucked her tight pussy. Barely taking a single moment to rest or slow down as he humped hard and fast into Garnet. He always had a thing for getting the usually stoic silent type to break, and the way Garnet was moaning so sultrily was revving his engine evermore. The waves and splashes in the pool grew to a feverish pitch, and eventually Leo couldn’t hold on any longer, filling Garnet’s shapeshifted slit with enough seed to breed her thrice over. Her orgasm had overtaken her as well, cracking the bowl-like pool they were in with how hard she’d thrown her hips back.

While he’d been in the barn for three days, he spent a whole week in the three women’s rooms before he got to see the light of day again.

A year later Leo followed through, and moved into Beach City with his wife. It was already one of the main gem hubs of the world, and admittedly he’d always sort of thought it would be the best place to settle once he’d seen the world. The Crystal Gems were also his crush from way back when, so getting to fuck them every day was a dream come true. Many others would come to visit him. The barn trio were constantly coming over, the Diamonds found a way to increase his size so they could get fucked on the beach for all the humans to see, and his wife couldn’t be prouder of his new job.

Perhaps it was for the best that no one ever realised the magic of the license. As a new prosperous age for gemkind would begin.
