Hiro wondered in how big trouble he'd find himself if Professor Granville found out what he was using the lab and its expensive equipment for. Although "using" was a misnomer too, as he really was a subject in hands of his three ingenious girlfriends...
He had to admit, a white labcoat clashed somewhat with Gogo's hair and her overall demeanour, but it most certainly matched with Honey Lemon's and Karmi's attires, especially as the three women had nothing else underneath to clash with.
With three pairs of hands tending to his clothes, soon the young hero found himself equally naked, as the three brilliant scientists decided to put him through a gauntlet of tests to prove his virility. And though he had faith in his beloved, he knew very well how "creative" can they get behind the bedroom doors.
- Alright, who booked the lab first? - Hiro asked, watching as the three women exchange knowing, sultry looks.
- Well, who else than the top student?
Karmi walked forward, eyeing him her piercing, inquisitive gaze, infused with additional layer of lust. she might no longer be his adversary, but that didn't mean she'd stop trying to one-up Hiro. After all, a healthy rivalry is a great motivation for progress.
Karmi's lips met Hiro's in a short, but hungry kiss, before her hand pushed him back from his sitting position back onto the lab table he was disrobed on a few minutes ago.
She jumped into his laps, her hands already aiming at his erect cock she guided towards her overflowing pussy, as a single drop of her heat made it to its head and make him shudder in anticipation.
Hiro raised his brow, mimicking her cocky expression, as his hands moved up and down her waist, waiting to bury himself in her wet sex. But next thing he knew, his arms were grabbed and pushed over his head, as two metal clamps closed around his wrists.
The same happened to his ankles, immobilising and spreading him on the table, to his mistress' mercy. Something told him Karmi's not gonna make it easy for him...
His worries were confirmed when she took her phone and started a timer, at the same time as her wet fold pressed against his cock, pushing his length against his body. And as Karmi continued sliding her sex against him, he realised what she's been measuring.
Her delicate, but steady moves were setting his entire body on fire, as he was dying to get out of his cuffs and made love to Karmi.
And knowing that it was entirely up to her made it so much more rewarding.
Somewhere around him, a slow, sensual music was being played, no doubt chosen by Honey Lemon, that only made it more difficult. Karmi moved her body to the rhythm of the song, her body swaying with the beat, driving Hiro crazy. her lab coat hid some of her curves, accentuating others, never showing him all the beauty hidden underneath it.
Karmi also knew exactly how to edge him, her lower lips traversing his length up to his head, but never touching it, knowing it would be a point of no return.
But as long minutes of his love torture went on, Hiro noticed change in her behaviour as well, as her moves became slightly more erratic and uncoordinated, and she began caressing her breasts, in absence of his hands and lips.
- You-you want it too, Karmi, don't-don't you? - Hiro huffed, thrashing his body against the table, holding his oncoming climax. - A-Admit it!
Karmi looked at her subject with astonishment in her eyes, as she herself was desperate to cry his name. For a few more seconds, the two fought wordless battle, before Karmi grabbed his cock, and leapt onto it, letting her warm, welcoming sex engulf him completely.
- Hiro! - she cried, as her equally needy body was torn with a climax at the same time as her edged boyfriend.
She threw her head back and let the passion consume her, as she cried her lover's name with each portion of seed he shot up into her sex.
Despite her powerful climax, Karmi did not slump over him, but remained seated in his laps, and when she regained her senses, she reached for her phone.
- Well, let's see how well did you perform - she announced it with the same cocky, confident tone that vanished when she saw the results.
- Well? - Hiro mimicked her, raising his eyebrow.
- 15 minutes 16 seconds... - she spoke, unable to meet his eyes - The average is... 15 minutes 10 seconds.
- And you know it could be way longer, if you didn't break first.
- Sh-shut up! - she exclaimed with faux annoyance - I guess that experiment is over...
The metal restraints opened up, releasing Hiro, who was immediately taken by Honey Lemon, who pressed him against her bosom.
- Aww, did bad Karmi made you limit your moves?
- Mhm-mhm - Hiro replied from between her breasts, peppering it with kisses.
- Don't-don't worry Hiro, I'm-I'm gonna treat you so much better...
And Honey Lemon wasn't lying. A moment later, the two hopped on a bizarre structure made out of multicoloured bubbles that shaped themselves to their bodies' forms, better than any water bed ever could. Honey's long legs and arms coiled around Hiro, as she kissed his face, neck and torso, eager to make up for the love torture he went through.
- H-Honey... - Hiro gasped, feeling her lips closer and closer to his crotch
- Ssh, Hiro, relax... After all, I want you to be at full strength...
Honey cooed, as she grabbed something from her labcoat. She brought the colorful rubber and showed it to Hiro.
- One of my inventions. - she stretched it in her fingers - But-Oh dear, I need to clean the apparatus first. Looks like the previous user forgot to...
She looked at Karmi, before ducking and closing her lips around Hiro's cock, with a few globs of seed still clinging to it. As his musky smell filled Honey's nostrils, she wished she could continue her part that way and just use regular measuring flask... But her idea was so much more fun.
And so, reluctantly, she let go of Hiro's cock, kissing his tip, before she slid the rubber on. She then jumped back onto the bubbly bed and spread her legs inviting Hiro between them. But she let out a gasp when she felt his mouth against her sex.
- What? - Hiro mumbled against her folds - It's only fair I treat you as nicely as you did me...
Honey let out a moan, as Hiro's tongue dipped between her lips and his face was pushed against her already overflowing sex by Honey's hand, digging into his ruffled hair.
Honey kept her younger lover at bay for the next few minutes as he ate her out, licking, kissing and nibbling at her sex, until even the bubbly bed couldn't withstand her squirming and thrashing when she coated Hiro's face with her fluids.
- Come'ere...
She grabbed Hiro by his shoulders and swiftly brought him against her chest again, her legs automatically closing behind his back, as if she was afraid he'd back away.
But Hiro Hamada did precisely the opposite, diving deep into her pussy with his condom-clad hard cock, testing the bouncing bed they were making love on.
He finally could unleash the energy his hips wanted to expel when Karmi was edging him, and as a result, Honey received twice the amount of balls-deep slams, making her voice rise with each one.
Between their bodies mashing against each other, their lips seeking each other out and his cock reaching into her depths, it came as no surprise that Hiro came to his edge faster than he expected.
- Honey! I'm cumming!
- Good, Hiro! - she spoke and looked at the monitor just as Hiro's voice cracked.
His hips thrashed against her crotch one more time, and she let out a satisfying moan, followed by a slightly more coherent statement.
- Eleven millilitres! Twenty... Thirty-two!
Honey kept looking at the screen, crying the number out with each stream of seed that filled her special condom.
- Forty! Fifty! Sixty! - she cupped Hiro's cheeks and kissed him - You are way above the average.
- Am-Am I?
The two looked at the screen, which now, despite Honey's assertion showed 0.
- Oh dear, it must have broken...
And indeed, when Hiro pulled out, he was greeted with a burst instrument and more of his spunk leaking out of her sex.
- Well, normal condoms can stretch to contain litres, I had to calibrate this one for average male ejaculate to make the sensors work...
- Don't worry, Honey, you still have proven what you wanted, didn't you?
Honey smiled and kissed Hiro again, her fingers closing around his cock, as she slid the remains of her condom.
- And I'm gonna clean the workplace now!
Honey spoke and took him into her mouth once more to lick any loose strands of his seed, before she was abruptly pulled back by Gogo, grabbing her hair.
- You. Me. Bed. Now. - she stated and turned around, as Hiro automatically followed her orders.
Hiro expected Gogo to ride him just like Karmi wanted to, but she simply got on all fours and raised her curvy ass into the air, spreading her folds, inviting Hiro between them.
- Come on, fuck me. I'd like to see you try. - she spoke nonchalantly, as she glanced behind her back at her lover, already positioning himself.
- Is that it?
He grabbed his cock and pressed it against her wet opening. But at the same time, he heard a mechanical noise behind him and yelped when something cold and artificial pressed itself against his ass.
- G-Gogo?! - Hiro gasped in protest
- What, are you gonna chicken out? - Gogo snickered - Let's see if you can withstand your own moves against you...
Hiro swallowed loudly and taking a deep breath slid himself inside Gogo's pussy, while the robotic arm behind him shoved the lubed dildo inside his ass.
Hiro had to grasp Gogo's waist harder to ensure his position, and after his next thrust let out a prolonged, high-pitched moan that caused Gogo to giggle.
But then she cried as well, when Hiro shoved himself unceremoniously deep inside her, experiencing the same feeling inside his ass. Though the thrusts now were much more difficult to achieve, Hiro didn't stop, knowing that correct penetration of Gogo would benefit him as well.
And indeed, as he carefully plunged himself into her, the awkward feeling of his mechanical lover turned into pleasure, and was soon properly rutting Gogo, while the machine ravaged him. Gogo grasped the edge of the table she was lying on, trying to withstand double amount of thrusts that multiplied its force against her.
With each one, she felt him deeper inside her, until he was barely against her womb, just like the dildo was inching around his prostate.
And when the final stimulation happened in Hiro's body, it send not just a shockwave in his body, thrashing it against Gogo, but the stream of his potent warmth made her shudder in pleasure. Several times more has Hiro dived into her pussy, bathing her in his seed, until he pulled out, parting somewhat reluctantly with his robot lover.
- Oh wow... I didn't know you'd do it... - Gogo gasped, feeling his seed oozing out of her pussy.
- H-Honestly, neither did I...
Hiro spoke and on his weakened knees walked back to the bubbly bed, where Karmi and Honey rested. Soon, the two joined forces in caressing his tired body, and even Gogo showed her more tender side, though she ended her portion with a slap to the butt.
- Well, I'd say that concludes our experiments...
Hiro sighed, basking between his equally tired girlfriends, before they all drifted to well-deserved sleep. But unbeknownst to them, another set of experiments has been put into motion, one that would take months to complete... Nine, to be precise. And with its results being confirmed not once, not twice, but three times, it would prove Hiro to be a supreme stud of the SFIT, even if he and his girlfriends expected that to happen a few years later...

So it's agreed that Gogo has the best ass, but who has the best titties in the Hirem? This requires analysis.
- Hiro, out of your four girlfriends, it is-
- Not that kind of analysis, Baymax. - Hiro interrupted him - And by the way, please power down.
- Yeah, it was a bit creepy when he suggested what is “the optimal angle of vaginal penetration” - Gogo quoted him - Anyway, what do you say about these puppies?
She lifted her shirt, pressing her modest breasts against Hiro’s face. Everyone knew Gogo’s butt was the bootiest of them all, but in case of breasts, Hiro had to admit, she was clearly outranked. Which didn’t mean he wasn’t enjoying Gogo’s aggressive form of foreplay.
Next was Honey, who gently uncovered her bosom, a tad bigger than her roommate’s, who already got to licking one of her nipples, while their judge tasted the other one.
A bright flash filled his vision as Megan leaned in, with the strap of her expensive camera sliding between her breasts in a flirtatious manner, attracting Hiro’s attention.
- Mhm, we gotta need bigger focal length for those...
- I think you slid your focal length between them last time. - Megan giggled, as Hiro kissed her skin - And it’s a good thing your cum missed the lenses, or you’d be dead...
And just when Hiro thought they had the winner, Karmi showed up, sporting her trademark sweater. As she slowly rolled it up, the others watched in awe, waiting for the drop, and they were not disappointed.
- Wow, how did you grow these so big?
- Oh, just good genetics, you know... - she smiled, fixing her hair - And some advanced DNA manipulation to make those genes behave like I want.
With four pairs of breasts surrounding him, Hiro knew the contest was never about picking a winner, it was about the variety and divine beauty he had privilege to see: from perky and modest, to big and bountiful, each of his ladies were graced with magnificent bosoms Hiro was dying to dive into...
- Okay, but Karmi clearly wins, though - Hiro added, being pulled against her chest.
When Hiro first made love to his girlfriend two years ago, he wouldn’t dream he would be able to spend an entire night doing this, let alone with multiple women. it felt like some sort of story men would brag about on anonymous internet boards.
And now, here he was, with his hands on Gogo’s thighs, who rode him furiously, and his mouth pressed against the wet folds of Megan, while his other two girlfriends rested waiting for another round with him.
Hiro thought that maybe his superhero duties, requiring lots of physical prowess, combined with the visits to gym in between the classes has helped him achieve his status. Or maybe it was the serum Honey and Karmi has secretly been working on and needed an unsuspected test subject. And from the copious creampies between their legs, it was working.
Fathers day- the hirem telling hiro that hes going to be one
- Why are we all gathered like this? - Hiro asked, eyeing his girlfriends, sitting around the spacious table of their kitchen, as if they were about to judge him.
- So, Hiro, do you remember how we were taught that even a mistake in an experiment can lead to precious, valuable data? - Honey Lemon started, fiddling with her fingers
- Yeah...
Honey looked at Karmi, and the younger woman continued.
- Well, at least now we know for sure that the contraceptive patches will work with the new batch once we found and fixed the flaw in the recipe...
- F-Flaw? - Hiro choked on his soda, as the realisation slowly dawned on him.
- Hiro, what we’re trying to say... - Megan took his hand, but was quickly interrupted by Gogo
- Baymax, search list of most popular names for children, print five copies, and catch Hiro.
Gogo addressed the enormous robot to move his hand to catch Hiro, who nearly fell off the chair at the prospect of being a daddy four times over.
Something told him he will require much of his help in the coming months.

The Hirem celebrating the end of exams with an All-American fuck party.
(Ao3)
As May was slowly coming to a close, so was the exhausting exam session across universities in San Fransokyo, in turn opening a new season of parties for students to celebrate the exams the have passed, or to drown the ones they will have to re-take. Hiro has already attended a few of those, finally being of legal age to drink, but it wasn't until last day of May that he would attend one particular, private party.
He wondered if right now anyone else in the many fraternity homes across the town was having such a great time, embraced in a passionate, loving lock with two other people, undressing each other each kiss. Karmi was easily the most agressive kisser of them all, as evident by hickeys all over Megan's body, who was sandwiched between the two, being the subject of their caresses tonight. After all, she has just finished her first year of college, and it was only fitting if Hiro and Karmi gave her an appropriate present.
The young journalist could finally relax in arms of her lovers. Hiro was tending to her breasts, while Karmi's hands already sneaked between her legs, her fingers dancing along her slit, while her mouth tended to her neck. As the two junior students continued their journey across Megan's body, their faces soon met, and they exchanged a brief kiss, before each one of them took care of one of Megan's breasts. Though one might think that Hiro and Karmi would have put their rivalry beside them, as they were now together, nothing could be further from the truth. If anything, love life only exaggerated their passion for competition, and right now, they each made sure to caress as much of their respective mound as possible, with Megan as an impartial judge.
Hiro concentrated on her right nipple, sucking on it, while Karmi started with area around her left one, sliding her tongue underneath her breast, or, despite Hiro's protest in between them, which they have dubbed the "no-man's land". And Karmi was punished for cheating, when Hiro's hand sneaked between her legs, causing the young biochemist to yelp, which in turn gave Hiro chance to lick the other nipple of their subject. In turn, Karmi grabbed and shoved Hro against the bed, while her hand coiled around his cock, but it was Megan's voice that put them at ease.
- Are you guys gonna keep bickering, or are we gonna fuck?
Karmi and Hiro exchanged knowing looks, before they got up and crawled towards their lover, assuming their positions, though perhaps not the ones Megan expected. She eyed Hiro, as he cirlced aroud her, and only when he gently tilted her head back, she understood what the two were planning, especially when she felt Karmi's hands spreading her legs.
- Ready? - Hiro addressed Megan, and received an encouraging upside-down nod.
Megan opened her mouth and watched as Hiro's cock slides against her face, while her sex was pressed against Karmi's crotch, aking her automatically close her legs around the girl that was scissoring her. Though Hiro wanted to use her mouth, Megan played by her own rules, giving him slow, meticulous licks at first, just so his journey down her throat would be easier. She let out a prolonged moan when first glimpse of his taste hit her, and that accelerated her desire to feel him in her mouth. Her lips closed around his tip at the same time, as Karmi's lips brushed her clit, making the girl in the middle shudder in excitement.
And when Hiro slid into her mouth, he and Karmi could start working on their girlfriend. True, rivalry was baked into their relationship, but so was cooperation, and when the two did work together, Megan could see how marvellous can two brilliant minds of SFIT be with their powers combined.Though Hiro never considered himself a rather gentle lover, he had to admit, seeing the head of his cock bulging Megan's throat made him feel truly dominant. Conversely, Karmi, who usually preferred angry, fast sex, enjoyed her slow moves against Megan's pussy, listening to her moans, muffled by Hiro's cock. Her fingers tended to Megan's clit, whenever her own wouldn't brush her enough, and she could feel underneath her fingertips the goosebumps that waved through Megean's skin with each of her pushes.
Though she was sandwiched between her two lovers, Megan wasn't idle. Her hands, closed around Hiro's hips, often meandered to his testicles that bounced upside-down in front of her eyes and nose, filling her senses with his musky smell, mixed with a hint of the cologne the girls bought for him on his last birthday. She could feel the tension underneath the skin, caused undoubtedly by weeks of celibacy caused by the exams. Under her gent;e touch, Hiro moaned her name, and somehow Karmi knew she would be able to relieve him of his suffering soon.
But at the same time, she was close as well, due to Karmi's relentless grinding against her sex. With each passing minute, their joined bodies rocked in sync faster, until their moans, both audible and muffled became one. Seeking more stimulation, Karmi leaned forward, just enough so her lips could touch Hiro's, and that made him sheathe himself fully for the first time into Megan's mouth, with each subsequent thrusts only repeating this feat. Her arms and legs were flailing with each spasms of pleasure, and under this much stimuli, it didn't surprise her that she was the first one to cum, soaking Karmi's finger and sex with her explosive orgasm. Hiro followed her soon,, flooding her mouth with his cum and painting the rest of her face white on his way out. and finally, Karmi, with the help of her and Megan's fingers came last, falling to the bed after her hips travelled an exhaustive run across Megan's pussy.
Megan felt dizzy, and not due to her world being turned around. Her body ached with each wave of her climax, strengthened by the stickiness of Hiro's climax in her mouth, belly and on her face, contrasting the sublime wetness of Karmi's on her pussy.
Their boyfriend was quick to handle them towels, and helped the freshman girl roll to her belly, just so she can take a proper breath of air. With her mouth somewhat clean of his spunk, she reached for Hiro's lips, just before Karmi waddled to demand a kiss of her own too, though she didn't mind taking a bit longer to taste a bit of Hiro with her tongue.
- You know, this is always what people told me college would be like, but I never thought this could be real. - Megan spoke, once her lips were free from either of her lovers. - I guess I'm just lucky I have you.
- Oh, you are so sweet. - Karmi spoke - But don't think we're done here.
She grabbed her arms and pulled her over her, her arms automatically locking behind Megan's back, while her lips kissed her again. Megan didn't have to ask what Karmi had on her mind, the sound of Hiro's blissful sigh told them they were exatly in the position Karmi wanted.
With their glistening pussies pressed against each other, Hiro's cock sprung back to action, and as he positioned himself against their joined entrances, he was faced with another difficult choice. He wanted his ladies to feel the same burden and pressure, so he made sure to slide his cock from one entrance to the other, giving each one some hope they would be the first one to get penetrated.
And just when he was about to make a final decision, he heard metallic noise from behind him, as the door to Megan's flat were being open.
- I see you've already started. - Gogo started with a snarky comment, looking at the three younger students ina rather compromising position.
- Well, come on, don't keep us in suspense! - Megan addressed, turning towards Honey Lemon.
Once the tall girl was inside, she looked at all three of them, shied away for a moment, and then burst into a fit of ecstatic giggles.
- I passed! I finally can drive my own car!
The other three cheered with her, though in their somewhat embarrassing position it looked awkward, but that didn't stop Honey Lemon from reaching each of them for hugs.
- And the best thing is, I only hit *one* tree!
- Wait, then how did you pass the test exactly...?
- The rubber balls. - Gogo explained, sitting on the other side of the bed.
- I was in the middle of the road, was about to crash, so I thought "why not just use what I have in my purse?". So I just stood up and shot the tree with my projectiles through the roof of the car. And I guess the instructor was so impressed that he let me pass.
- He might have also passed out afterwards - Gogo added.
- Wow. That's... unusual... - Hiro commented - But hey, now we have another thing to celebrate!
- Thanks, guys. - Honey Lemon cooed.
- Hey, aren't you gonna tell them about my exam?
They all turned towards Gogo, and as their eyes lay on her, they realised that while Honey was talking about her experience, Gogo was busy undoing her clothes. The naked girl crawled towards them, grabbed Honey Lemon's coat, and slid it down in one swoop, exposing her breasts to the other three.
- Oh, yes! Gogo had a very important one in her new job! - Honey Lemon exclaimed, while she continued undoing her clothes on her own.
- A health and safety one.
- And she aced it!
- I just sprayed someone with a fire extinguisher. - she blew and popped a piece of bubble gum.
- But you know what that means? - Karmi added - We all passed our tests!
- Not quite. - Gogo interrupted her. - There is still one ahead of you, Hiro...
And as the four stunning, naked ladies turned towards him, eyeing him with their lusty stares, young Hiro Hamada understood this might be the most important exam of his life. And for once, he wouldn't mind retaking it over and over again...
While I’m on the “overworked scientist” kick, how about Hiro spending a long night in his garage only to be greeted by a topless Gogo about halfway through, taking frequent breaks from his evening project to hump her into the desk
And maybe if Gogo gets tired out, she sends for backup in the form of a bottomless Honey Lemon (or maybe even a fully nude Karmi)
Hiro might have been a great and talented inventor, but whether he liked it or not, presenting his invention wasn’t enough; he had to write his master thesis as well. And Aunt Cass was more than happy that Gogo and Honey, who have already graduated, were so eager to help him.
What she didn’t know was that their help had usually nothing to do with his academic paper. The two older girls took it it as a duty to de-stress their young genius boyfriend by spreading their legs and letting him release his pent-up energy any way he wanted. And when each chapter of his work was done, the two would reward Hiro by combining their forces, which often resulted in spectacular climaxes being poured into their mouths or pussies.
And with his mind achieving the state of clarity thanks to a powerful orgasm or two, he honestly felt he was better at proofreading anyway.
So, who's the first member of Hiro's harem to get knocked up?
Hm, I think Karmi, she’d be more than keen to conduct an experiment on how their genius genes can mix. And she might or might have not already written a fanfic about Captain Cutie doing that to her alter ego..
