Quill craned his head, nearly pushing his nose against the glass window as he tried to get a better look at the part of town his boyfriend, Gabe, was driving them through. It wasn't too far from downtown, in reality. The block had a large rehab clinic, a big modern gym, and a large farmer's market next to an upscale coffee shop all one after the other. Certainly a more respectable part of town than their usual haunts.

The green cat turned to his boyfriend and asked, “So when are you going to tell me where we're going? And why you asked me to wear this specifically for the occasion?" He stretched himself out emphasize the outfit; a black leather vest, black leather cutoffs, and matching black thigh-high boots and long gloves, accented by gold buckles around the frayed edges of the cuffs. It was usually the kind of thing Quill wore when the plan was to spend a night getting his asshole stretched open in the bathroom of a gay bar. He couldn't remember the last time he wore it when the sun was still up. Although it did shine really nicely with how bright the sky was outside.

“Just something I wanted to check out. You said you wanted to get out more," Gabe said, trying his best to be nonchalant. Quill eyed him suspiciously. His boyfriend, at first glance, might seem like a totally normal cat. His fur was a creamy color like a latte, and his hair was a light blond. He was well-built, with strong arms and shoulders, but nothing excessive. The first clue that there was more to him was his great height, which forced him to hunch in the interior of their sedan, his knees pressed up against his chest to let his feet rest on the pedals. But in that posture, Quill could see the bulge that stretched the crotch of his sweatpants taut beneath his loose hoodie, and watched him tug uncomfortably at the leg to accommodate the huge impression running from thigh to knee.

“Yeah, but you said your balls are feeling more backed up than a rush hour highway, remember?" Quill whined. “I thought we were going to take the weekend off and have sex! I even got a new bottle of lube!"

“I didn't say we're not doing that," Gabe corrected him. “I just saw this ad on TV and I wanted to check it out before we shacked up for the weekend. It's probably nothing," he said, looking toward his boyfriend with a grin.

“So what's it for then?" Quill repeated.

“I told you, it's a surprise," Gabe said, reaching out to give Quill's thigh a squeeze. “And if you don't quit bugging me, I'm gonna stuff that mouth full by making you give me some road head." Gabe tugged at the crotch of his pants again, trying to loosen them around his aching balls.

“Promise?" Quill replied with an impish grin. Gabe just reached over to tweak his ear.

As they rounded the corner, Gabe saw it first, his eyes lighting up. “Here it is," he said.

It was another clinic, looking a bit more modern with a glassy exterior. It would have looked very sleek and polished if not for the sign that read “JIZZLABS" in big, bold letters, with the cartoon image of a rabbit's face clenching in the throes of an intense climax next to a logo that combined a male symbol to make the arrow look like the tail of a sperm cell. The walkway leading up to the clinic was nice and paved, framed by some minimal but professional landscaping, but all of that was rather cluttered now, as quite a commotion had amassed outside the front door. There were several open booths set up with tables and some strange machines with nozzles and hoses and whatnot, and men of various sizes gingerly examining the setup. Above it all, a banner hung from two big poles, reading in big print: “SPERM DRIVE!"

“Oh… my… god…!" Quill gasped.

“Looks like it's not too crowded," Gabe said as he found a parking spot, examining the crowd. “I'm not sure anyone's even getting milked right now."

“Gabe," Quill stopped him as he parked before they got out of the car. “Is this really…?"

“Well, it's a sperm bank," Gabe said. “I guess technically you'd call it a fertility clinic? I don't really know. I just saw some commercial for this 'sperm drive' thing. I guess it's for research? It might be for babies. I didn't catch all the details. I think I can see some brochures on a stand, though," he said, angling his head to look out the window. Quill was utterly speechless, his mouth hanging open as he stared at Gabe. When he noticed, he just shrugged and said, “What? I thought you'd like the idea. You said you wanted to experiment more, try some more exciting sex stuff."

“What are you talking about? I love it!" Quill said, his grin brightening. “Were those milking machines out there? On the front lawn!?"

Gabe grinned. “Only one way to find out."

They ran out and headed up the front steps to where the drive was being held, set up on top of several different white tarps. Indeed, a few “private" booths were set up with some curtains, but many of them were open, showing them to be little more than office chairs, some porn magazines, and a glass vial for the “samples." But the real centerpiece was a large milking machine; the seat looked like a dentist's chair, but overhead was a large, bulky device from which hung a suction tube and nozzle, with a detachable head, and a few other parts and pieces that the cats couldn't make heads or tails of. It seemed very high-tech and impressive, but the clear tank underneath the chair was empty.

As they looked around, they could see why. There were a few other men here - a chubby bear guy, a handsome buck, a skinny rabbit, a stout raccoon - but they all looked more nervous than anything. They milled about at arm's length, not getting too close as if the place might suck them in, gingerly looking at the booths and the milking machine but not daring to approach or hold eye contact too long.

A booth opened, and a big, fat, pig man came out, buttoning up the top button of his shirt, looking sweaty and red-faced, holding a rolled-up magazine under his arm and a vial of what was clearly his fresh essence. “Uh… here ya go, doc," he said, heading over to the sign-up table nearby. Everyone was looking at him as he emerged, and that only made him look more mortified.

The doctor in question was a tall mouse with gray fur and blue hair, dressed in glasses and a labcoat. He straightened his posture and brightened with excitement as he accepted the vial. “Oh, yes! Perfect! This looks like a good specimen! Feel free to help yourself to our refreshments! And thank you again for your donation, sir! You'll receive confirmation in the mail within ten business days!" he said, but the man was already shuffling off, pulling his hat down over his eyes.

As the cats entered, they started to get similar stares from the meandering potential clients, especially Quill with his wide hips, soft thighs, and slutty nightclub outfit. Although when the rabbit spotted the bulge running down Gabe's pantleg, he looked like he might choke on his own tongue. Quill leaned up to whisper into Gabe's ear, “You think they're just having a slow start? Or is this place kind of a dud? No one's even getting milked."

“We just got here. We should at least check it out," Gabe replied.

“Fine, but one dude jacking off in a stall is just a gas station bathroom, not a hot new sexual experience," Quill quipped.

No sooner had the two approached was the mouse doctor springing up from his seat behind his table, nearly bumping into it as he rounded the corner to greet them, shaking their hands eagerly. “Oh, good morning gentlemen, good morning! Welcome to JizzLabs, and our first official annual Jizzapalooza Sperm Drive! Forgive me, but I don't believe you're regular donors with us?" he asked with smile.

Quill looked up at Gabe, who did the talking. “Uhh… no, we're not. I just, you know… saw your commercial on TV…"

“Yes! Splendid!" the mouse said. He took a look at each of them and said, “Well, it looks like you two came dressed for the occasion! I am Dr. Thomas Gray, founder and head researcher here and JizzLabs. Now, are both of you looking to sign up, gentlemen?" he asked, holding up a clipboard.

“We're not even sure what this place is," Quill said. “Is a 'sperm drive' supposed to be like a blood drive or something?"

“Yes, precisely," Dr. Gray responded. “You see, here at JizzLabs, we pride ourselves on being the first fertility clinic designed to emphasize and maximize male pleasure during the sperm donation process. The sperm we receive is used for fertility purposes, but also research into cutting-edge genetic science, as is the data we collect from our state of the art sperm collection machine." Here, Dr. Gray motioned toward the impressive machine at the center of the event. “The JizzMaxxx Ultra Male Orgasm System 9000 is the pinnacle of engineering and data analytics, designed to maximize male pleasure during donation with a variety of stimulation methods all honed precisely by a learning algorithm that can learn the preferences of each client even during the middle of his donation. It truly is one of the most gratifying experiences one can have while donating sperm."

The two cats looked over at the machine, impressed by his claims, but not by its lack of traffick. “But no one's using it," Quill pointed out.

“You ever think about not putting right out in the open where everyone can see you getting your dick milked?" Gabe suggested bluntly.

Dr. Gray flushed slightly, adjusting his glasses as he sheepishly explained, “Well, you see, the machine wouldn't fit into one of the booths, so…"

“So why not just do it indoors? You have that whole clinic, right?" Quill asked.

“I… I thought that the sight of the JizzMaxxx at work, and the, well, thrill of it all might be better off overall for the drive by attracting foot traffic…?" Dr. Gray answered.

“Seems like you're just scaring everybody off," Gabe commented as the buck headed down the sidewalk. “How many donations have you had all morning?"

“Two," Dr. Gray answered. “Our goal is, uh… ten gallons of semen," he said, gesturing to a large plywood sign with a graph to be filled in with marker, showing how much had been donated yet. So far, only a single red line had been drawn at the bottom of the glass vial.

“Ambitious," Quill remarked with a smirk.

Dr. Gray recovered his composure. “But, maybe you two gentlemen are feeling more adventurous? What do you say? Care to make a donation or two?" he asked with a smile. When the two didn't answer immediately, Dr. Gray's expression weakened as he added meekly, “It's for a good cause!"

Quill and Gabe exchanged glances, sharing their impressions wordlessly. They'd already come all this way, and the doctor seemed like he was in a bind. And it wasn't the craziest thing they had ever done.

So, with a slap on Quill's ass, Gabe put on a big grin and said, “Yeah, Quill would love to donate!"

“Wait, hang on!" Quill protested as he was shoved forward, but Dr. Gray's face had already lit up with excitement.

“Splendid!" the mouse said. “Right this way, sir. I promise you won't regret it, and your contribution is very much appreciated!"

“Don't be shy, Quill. This is the adventure you were looking for, right?" Gabe teased him. As they walked forward, he kept a paw on Quill's ass, kneading it to make a shiver run down his spine and through his tail.

“Why do I have to go first? You're the one with the huge nuts!" Quill grumbled quietly in protest to his boyfriend.

“Because you make such cute noises when you cum," Gabe replied simply, a frustrated flush crossing Quill's cheeks.

Dr. Gray led the two up to the milking machine, the chair open and awaiting them, the sleeve and hose looking ominous in the promise of what it might do. “Very good! Now, feel free to disrobe, and we can get started," the mouse said. “Would you like any visual stimulation to help with arousal before we begin?"

“'Visual Stimulation?'" Gabe repeated with a blank blink.

“He means porn," Quill quietly explained.

“Oh. No, he won't be needing any of that. I can get him worked up for you," Gabe said simply. Before Quill could ask what he meant or stop him, Gabe grabbed the waist of Quill's tight shorts and tugged them down.

With a gasp that neared a squeak, the green cat was suddenly exposed. The curves of his waist gave way to his wide hips and plump butt beneath his fluffy, swishing tail, but the real prize of the moment was his manhood. His shaft was plenty long and thick, even when flaccid, and his balls were equally plump, his soft coinpurse full and round with all of the pent-up essence he was ready to donate to Dr. Gray's cause.

Quill flushed and smacked Gabe's chest in protest, “You can't just strip me naked in public like that, you jerk!" he complained.

“Oh, it's quite alright! I assure you, we have all the necessary permits to do this. No reason to be shy, this is all a natural process, after all," Dr. Gray reassured him.

Quill folded his arms as he kicked his shorts away from his ankles. “And of course this is all just business for the good doctor? Not getting off on this at all, right?" he said in a dry tone.

“Of course, of course! Anything less would be highly unprofessional of me," Dr. Gray insisted.

“You're blushing, doc," Gabe teased with a grin.

Dr. Gray chose to ignore the comment as he said, “Now, when you've got your erection, take a seat in the chair, and the JizzMaxxx will get right to work."

“One boner coming right up," Gabe said.

“Hey, what are you-" Quill started another protest, but was cut off as Gabe shoved him forward, making him bend over and brace his hands against the JizzMaxxx's seat. A moan finished his sentence as Gabe pressed behind him, reaching around to start stroking Quill's cock, his other hand holding Quill's head firmly by his hair while he ground his own bulge against Quill's ass. “Ohhh…!" the green cat groaned as he started to shiver.

“That's better," Gabe grinned. Dr. Gray watched with wide eyes, as did the few onlookers, the first bit of real action the drive had seen all day, and the horny noises coming from the two cats were sure to cause a scene.

The presence of eyes on him, as well as Gabe's strong fist pumping his cock steadily, not to mention the feeling of Gabe's own huge bulge grinding against his butthole made Quill's cock start to stiffen quickly. “Ohh, you're not playing fair," Quill whined, but he couldn't help shoving his rump back into Gabe's body in one direction and bucking his hips forward to fuck Gabe's fist in the other, his fingers digging into the synthetic leather of the chair.

“I never do," Gabe growled, his husky, horny voice sending another shiver down Quill's spine, especially when paired with a rough nibble against the base of his ear. Gabe wasn't about to back down though, stroking faster as he kept up his dirty talk. “Look at you, little kitten. Already getting hard and leaking precum all over the pavement."

“Ohhh…! Shut up…!" Quill protested, but it was true. As Gabe took more control of him, yanking his hair back to make him grind on Gabe's bulge while he milked his cock with his hand, Quill's erection grew quickly until it was clear and firm, throbbing as beads of precum formed clear, sparkling strands that began to leak down between his footpaws.

“I think he's ready, doc," Gabe growled at the mouse, who snapped out of his wide-eyed reverie into action.

“Yes! Yes, of course! Let me just get you measured so we can use the proper sleeve size…" Dr. Gray said. Gabe relented only slightly as the mouse produced a small tape measure, releasing Quill's cock to let his erection bounce up and stand proudly on its own, still holding him tight by the hair with his hand gripping his waist possessively. Quill could only watch the mouse crouch down to eye level with his cock, marveling at his twitching, leaking member as he held the tape measure to it. “Oh…! Eight inches! Very impressive! Looks like you'll be using our large sleeve!"

“Hear that?" Gabe teased. “The doc says you've got a big dick. Congrats, kitten." Again, Gabe gave Quill a loud spank on the ass, his cheek rippling from the impact.

Quill gave a horny grunt at the strike but replied sarcastically, “Oh, thanks."

“Go ahead and take a seat, and we can get started," Dr. Gray said as he retrieved a clear, sleek cock milking sleeve labeled with a big “L" and began to attach it to one of the hoses on the machine.

“I think he's good just like this," Gabe said. “Bent over, getting milked like a cow? Definitely a good look for you," he purred.

Quill just whined as the dirty talk and arousal built by the moment, his penis still twitching beneath him, oozing even more now that he wasn't being actively pleasured. But Dr. Gray approached and said, “Alright, but if you need to sit down, let me know. The JizzMaxxx is very powerful; I wouldn't be surprised if you had trouble staying on your feet."

Quill just rolled his eyes and said, “It's a dick milking machine, how crazy could it actually be?"

Dr. Gray just shrugged and said, “Suit yourself, sir," but the tone sounded more like 'it's your funeral.'

The mouse slipped on a pair of rubber gloves before stepping in front of Quill again as he squeezed a generous amount of clear lubricant into the slotted opening of the sleeve from a bottle. Then he unceremoniously grabbed the base of Quill's cock in one hand and the sleeve in the other before shoving his erection inside with a loud squelch.

“Oh-!" Quill gasped as he felt his penis enveloped completely. The sleeve had some kind of synthetic internal flesh with a strange texture, nothing even close to the insides of another's body, male or female, yet the ridges and planes felt perfectly smooth and highly stimulating all the same. The grip was very tight, but not too tight, with just enough give as if conformed perfectly to the shape of Quill's penis, and sheathed all the way down, fully balls-deep, a little lube even leaking out warmly onto his ballsack.

But Gabe wasn't going to let a machine do all the work. Before Quill could fully adjust to the feeling of his dick buried deep inside the milking sleeve, he felt Gabe's paw grabbing the base of his tail and yanking upward. He only had a second to exhale, but before he could even turn around, he felt Gabe's tongue shove itself into his butthole, his lips fervently making out with his backdoor. “Ohhhhh-!" he moaned, quivering at the sudden burst of sensation.

Dr. Gray's face was quite red, but he stood by the JizzMaxxx's base and said, “Are you ready?"

“God, yes!" Quill moaned, raising his hips and letting his cheeks part for his boyfriend's muzzle. “Milk me, doc!" he begged.

The mouse flipped the switch, and with a steady, rising hum, the machine rose to life, then roared into full power. Immediately, Quill's cock was assaulted with a barrage of sensations, pumping, sucking, twisting, stroking, squeezing - like pounding a tight hole, getting a blowjob, and getting a handjob all at once, and more. The synthetic flesh of the sleeve seemed fine-tuned to the details of his penis, buzzing against every sweet spot, working every angle, pressing every button he had in all the right ways. And then there was Gabe's tongue invading his asshole, soft and pliant, stroking around his ring in circles before plunging inside, working him from the back while the JizzMaxxx worked him from the front. The effect was nothing short of overwhelming.

“HOLY FUCK!" Quill blurted out. It was almost too much; going from almost zero to a hundred in an instant, straight from erection to orgasm before he could even begin to process all the ways the JizzMaxxx was milking him. His hips bucked involuntarily, his vision went blurry, and in a matter of seconds, Quill lost all control. “Oh fuck, I'm cumming! I'm cumming!" he wailed.

Gabe only stopped eating out his boyfriend's ass long enough to express his surprise. “Wait for real? Already?"

But before Quill could even confirm, it was happening. His body seized, stars exploded across his eyes, and his balls clenched hard as they pumped his cum deep into the JizzMaxxx's tubes. The machine was perfectly programmed for it, switching to a rhythm and sensation that was still overwhelming, but designed to maximize the output of his orgasm. Quill felt like the cum was being sucked right out of his balls, the blasts of white that traveled down the hose bigger than he'd ever came in his life. His fingers gripped the arm of the chair as he moaned and writhed in delight, breathless and speechless. When it was over, he was left trembling in the aftermath of one of - if not the most - powerful orgasms he'd ever had.

And then the JizzMaxxx just kept going.

“Shit…! Ohhhh, fuck yes!" Quill whined. The overstimulation was almost distressing, too much for his brain to process, a roller coaster ride that was too much for his body, but he couldn't get off. The pump resumed its previous breakneck pace, throwing every bit of stimulation it had at him in every way all at once. His cock was forced back to hardness in a matter of moments, his balls being made to give more whether he was ready or not.

“Yeah, look at you go. Let's make sure the doctor gets every last drop out of you," Gabe teased. Again, he returned his tongue to Quill's butthole, but when his ass was as loose and spit-shined as ever, he shoved a couple fingers inside, making Quill yelp, as he started to pound in rhythm with the JizzMaxxx, working Quill's prostate with the same rough, forceful touch.

“Oh god, I can't! It's too much!" Quill whined. But those whines rose higher, his eyes losing focus, until they became moans of utter bliss. “I can't stop! I'm…! I'm gonna cum again…!"

And within moments of his first orgasm, he did just that, screaming in agonizing bliss as Dr. Gray's machine milked him for every last thick, sticky drop his balls were worth. By now, Quill had made quite a spectacle of himself, and he found himself surrounded by a dozen or so men looking curiously at the scene, many of them nursing tents in their pants and wary, if not curious stares at the machine itself.

After Quill's third orgasm, he was utterly tapped out, collapsing forward, his knees unable to support himself. Dr. Gray powered the machine down, and finally it released Quill's cock with a wet slurp. Quill could only slump against the JizzMaxxx's seat, fighting for breath as his senses returned to him.

“Looks like… a gallon of fresh semen! Very impressive! Oh, this is a wonderful donation!" Dr. Gray celebrated as he looked at one of the clear tanks at the base of the JizzMaxxx machine, filled with Quill's very own fresh, pearly sperm.

“You hear that? You just came literal buckets," Gabe teased Quill, pulling his fingers out of Quill's ass only to rub his butt affectionately.

Quill fought for words, but he managed to look back at Gabe and reply between heaving breaths, “Let's see you try it, big guy."

Dr. Gray's ears perked up immediately. “Oh? Would you care to make a donation yourself?" he said, looking up from his clipboard to Gabe.

Gabe couldn't help but be a bit wary of the machine after seeing what it had done to Quill. But at the same time, seeing Quill cum his brains out with such intensity was also very tempting.

“Why not?" Gabe said with a shrug. As he started to shed his clothes, he added, “But you're gonna need a bigger sleeve."

He tossed his shirt aside and dropped his sweatpants, and there were several audible gasps, even from Dr. Gray, as Gabe's huge, meaty horsecock flopped out, his flare already throbbing, his huge, heavy balls hanging low and full between his thighs.

“Y-you're a hybrid…!" Dr. Gray exclaimed, his eyes shining brightly.

“I get it from my grandad," Gabe explained.

Dr. Gray looked almost giddy as he quickly whipped out his tape measure and took Gabe's massive shaft in his hands. “My, you could even give some of the larger stallions I've seen a run for their money… Eighteen inches is nothing to scoff at!"

“Told you," Gabe said, basking in the attention and the murmurs from the other clients when they heard the number.

“We'll need to use our biggest sleeve," Dr. Gray said as he went to retrieve a much larger, longer tube marked “XXXL" from the JizzMaxxx's base. “Normally the triple-XL is the one we reserve for actual draft horses! But I think you should take a seat for this one. It looks like it could be quite the ride!"

“Oh, I can't wait to see this," Quill said, managing to pull himself to his feet as Gabe laid out on the padded seat while Dr. Gray lubricated the sleeve.

“I bet I'll do fine," Gabe said confidently. “Hell, I bet I can do the rest of the nine gallons the clinic needs for its goal no problem." He grunted as Dr. Gray unceremoniously gripped his horsecock beneath the midring and fed it into the sleeve with another loud, lewd squelch until it was flush with Gabe's crotch.

“Good luck," Quill said in his own teasing tone, booping Gabe's nose as Dr. Gray flipped the switch.

Immediately, the overwhelming assault of every possible sensation flooded Gabe's body as his horsecock was milked as hard as possible. Gabe nearly doubled over, his eyes going wide as he reached to grip the sleeve, blurting out, “HOLY SHIT!"

“Told ya," Quill smirked as he saw Gabe writhe and toss, his cock locked in the grip of the machine that milked him relentlessly.

Gabe fought for breath, his chest heaving and his eyes swimming as his hips pumped hard into the sleeve. But there was a strain to his voice that wasn't there for Quill. “Fuck, it's too much! It's too tight! I can't…! I'm gonna…!"

But before he could, before the JizzMaxxx could milk his horse balls for their hot, gooey payload, Gabe's orgasm was cut short by the machine giving a high-pitched whine before there was a sickening crack! And then, in an instant, the sleeve burst, long cracks forming along the sides as the synthetic flesh spilled out through the casing, and the JizzMaxxx powered down.

The onlookers gasped, wondering if Gabe's dick was okay, but he didn't seem to be in any pain. If anything, there was relief. Dr. Gray looked horrified as he ran to Gabe's side. “No no no! What happened?"

Even Quill looked perplexed. “Yeah, what happened, Dr. Gray? You said you use the triple-XL on real horses!"

Dr. Gray started to pull the remains of the milking sleeve off of Gabe's cock with sticky, lubricated slurp as he examined the firm erection beneath. “No injuries, thank heavens," he said. But then, crestfallen, the mouse adjusted his glasses as he said, “It seems that I was a bit too eager to get your donation, and I neglected to let you get a full erection before placing you inside the sleeve. So when you got hard, your penis grew, and, well… even the triple-XL wasn't big enough. And I'm afraid I don't have a quadruple-XL."

Gabe was fighting for his breath. Even after less than a minute in the JizzMaxxx, he was brought to the brink of orgasm and was now deliriously blue-balled. “If I don't cum, I think my nuts will explode," he complained.

“But without the JizzMaxxx, how will you reach your goal? You still have nine whole gallons of cum left to go!" Quill said.

“I don't know," Dr. Gray said forlornly. “Perhaps this was a stupid idea after all."

There was a long moment, the spectators watching on, where it seemed like the show was over, and people started to shuffle away from the clinic with nothing to watch and their embarrassment returning. But Gabe looked at Quill and started to feel his resolve returning.

“Guess we'll just have to do things the old-fashioned way," he said. He started to clamber out of the chair, keeping his thighs spread wide to nurse his tender balls.

Quill and Dr. Gray watched quizzically, and Quill said, “What are you talking about?"

But Gabe didn't need to say anything. He got to his feet, his toweringly huge horsecock twitching and oozing precum, his balls looking bloated and heavy with sperm. He simply turned toward the mouse and said, “Doctor, get a bucket."

Before he could ask why, Gabe simply grabbed Quill's hips, bent him over Dr. Gray's registration table, slamming his chest to the surface while yanking his tail up simultaneously, and in one heavy thrust, he rammed every last inch of his titanic horsecock into Quill's asshole.

There was a gasp; it didn't seem possible for one little cat boy to take such a massive dick, let alone in one heavy thrust. But Quill's back just arched, leaning into the pounding as he cried out, “Oh, Gabe! Right here?"

“Right here," Gabe confirmed. With his grip tight on Quill's hips, the bigger cat started to fuck the hell out of his boyfriend, his hips pounding into his soft ass with loud, lewd smacks as his butthole stretched around that massive horsecock. No one else could have dreamed of taking it, but Quill was used to bottoming for his boyfriend, and was the only one who could even dare such a feat. Gabe's nuts swung in heavy arcs to smack into Quill's, but the smaller cat just leaned back, bracing himself against the table as he mewled in delight.

“Ohh, yes! Fuck me, Gabe! Don't hold back! Give me that big, fucking horsecock!" he whined, his voice almost drowned out by the clap of his asscheeks against Gabe's body as he was fucked senseless.

Dr. Gray scrambled to keep up with the pace, but soon he placed a bucket beneath the pair of rutting cats as he worked to unwrap a condom. “Here we are! A bucket for your donation, Gabe! And Quill, you can ejaculate into this condom here…" It took the mouse a few moments to hold Quill's dick still enough to unroll the condom onto his shaft, but soon, the two were ready to unload.

And not a moment too soon! Gabe grabbed Quill by the wrists, knocking his balance out from him, pinning him to the table as he pounded like an animal, his huge cock a piston into Quill's plump tush. He moaned and growled above Quill, feeling his boyfriend's tight rump milking him almost like a machine itself. “Ohh, that's it, baby! God, your ass is so fucking good! Just a shame I won't be able to cum inside of it!" he grunted.

But that didn't stop Quill from begging all the same. “Ohh, Gabe! Cum for me! Cum for me, Gabe, yes!"

“Ohh, shit! Here we go…!" Gabe bellowed, his rough thrusting reaching a fever pitch as the group watched in awe before the bigger cat finally hit his peak. But instead of burying himself inside of Quill's asshole, he managed to pull out, letting his big, thick cock hang down, shoved up between Quill's thighs, dwarfing the smaller male's member as his equine shaft pulsed with meaty, orgasmic throbs. Then, finally, he erupted. Blasts of thick, steaming spunk exploded from his swollen flare like a firehose, hitting the plastic bucket with audible thunks! Gabe reached down to stroke the base of his cock in one hand while he reached around to stroke Quill's dick with his other, his gasps and grunts punctuated by the gushing sounds of the bucket quickly filling with potent seed.

Meanwhile, Quill's well-fucked prostate had brought him to the brink, and now Gabe's hand pumping his rubbered dick pushed him over the edge. “Ohh, Gabe! Milk me! Milk me!" he begged until he too was shuddering in climax, the green latex of the condom thinning and stretching as it ballooned with his seed. Although Quill had been thoroughly milked by the JizzMaxxx, he still had more than enough left in him to fill a condom with a donation, leaving a drooping bulb of white hanging from the tip.

“One gallon down…" Gabe grunted as his climax tapered off. But then, he simply Grabbed Quill's ass again and shoved himself back inside with a hearty squelch.

“Gabe! Gabe, my ass!" Quill squealed again, but Gabe was already plowing him, the table rattling with his own hip-shattering thrusts.

“I'll - I'll get another bucket!" Dr. Gray said, hurrying off to find more ways to store the donations that were coming.

One bucket became two. Then five. Then eight, not to mention a dozen filled condoms from Quill. The crowd and Dr. Gray were left in awe. No one believed that one horse-hung cat could cum so much. But the disbelief slowly began to morph into hope around the sixth bucket of cum. And now that eight were filled - a total of nine and a half gallons of sperm donated as Dr. Gray had marked on the chart - a small crowd had started to join the spectacle, and they had bought in completely.

A local news station even caught onto the event. A doe in a blazer stood in front of a news camera with a microphone with the sight of Gabe mercilessly fucking Quill over the table behind her as she spoke calmly. “What seemed like a fool's goal this morning is now a cinderella story in the making here at JizzLab's first annual Jizzapalooza Sperm Drive. Dr. Thomas Gray had set a lofty goal of ten gallons of man-glaze to be donated to research for genetic diseases and help infertile couples conceive, but thanks to the generosity - and virility - of these two shameless cats, it looks like that impossible goal might be within reach. With just a half-gallon more to go, the crowd has been eagerly watching all afternoon, witnessing the buckets fill up one ejaculation at a time. And now that these horny philanthropists are down to their last load, a small event's worth of witnesses has come to cheer them on in their charity. Take a listen," she said, pointing her microphone back as the crowd, which had about tripled in size, was pumping their fists and chanting as Gabe fucked Quill as hard as he could: “CUM! CUM! CUM! CUM! CUM! CUM! CUM! CUM!"

Sweat poured down Gabe's body, but his hips were unceasing, his grip on Quill's ass tight. Beneath him, Quill looked like he could barely stand, his cock swinging beneath him, trapped in a condom as his mouth hung open in an orgasmic stupor, his body trembling after being fucked hard and fast for hours now. Still, he managed to gasp back to his boyfriend, “Gabe! Gabe, I'm gonna cum again! Give it to me, Gabe! Cum in my ass! Ohh, fuck, yes!!!" Then, his body seized and writhed, his eyes crossed, and the condom began to fill once again with globs of his fresh jizz.

But the crowd knew that Quill wasn't going to push the goal over the edge. Gabe was, and the big cat was fucking his boyfriend's asshole like his life depended on it. Even Dr. Gray hovered behind him, his professionalism and decorum shed completely as he cheered him on like a corner man in a boxing match. “You've got this, you big, hung stud! Put those balls to work like a real draft horse! Take that big, fat horsecock and fuck that twink's ass until you cum your brains out!" the mouse cried.

Gabe's teeth were clenched, his fangs bared, his muscles pumped as he gripped Quill's butt and fucked him so hard that the table shook with every thrust. The crowd's energy and cheering, all the eyes and support fueled him on. “Yeah! Yeah! This is it! This is it! I'm gonna… fucking…! CUM…!" he bellowed.

He shoved his cock balls-deep inside Quill's ass, where he held there for several long moments. No one said a word. The only sound that could be heard was Gabe's strained grunts, Quill's mewling moans, and the gurgle of fluid being pumped out en masse.

Then, just when it seemed like it might never end, Gabe exhaled. He pulled back, and inch after inch after long, thick, meaty inch of horsecock pulled out of Quill's butthole as the green cat shuddered and writhed at the sensation of the fullness leaving him. Gabe pulled out of his stretched-out asshole, his flare coming free with a loud, audible pop! Then a gush of pearly white cum flowed out of him, splashing into the bucket, quickly filling it.

The crowd's roar was a deafening call of triumph. Dr. Gray marked off the last donation, the ten gallon goal officially met. Both Gabe and Quill got a myriad of pats on the back and words of pure awe from those looking on, and plenty of the men who watched the display excused themselves to the private donation booths on the side, ready to make the sperm drive even more successful.

Dr. Gray shook both of the cats' hands eagerly, beaming with pride. “I don't know how to thank the two of you enough! Truly, if there's anything I can do for you - or if you ever are in the neighborhood again - be sure to stop by! I'll make sure the both of you get the VIP treatment here at JizzLabs should you ever decide you'd like to donate again!"

Gabe just beamed back, cocky and satisfied, not even bothering to dress himself. “I'll definitely keep that in mind. Just make sure you upgrade those milking sleeves next time. Hell, maybe we can stop by again tomorrow," he teased, grabbing Quill's shoulders and pulling him into his side.

Quill smiled weakly, but stood with his knees far apart, his feet turned inward as he stooped forward. “Happy to help a good cause. But I think the only thing we'll be doing is putting our balls on a couple ice packs," he said.

Gabe looked down at Quill with a raised eyebrow at his posture. “You alright?"

“My ass…" Quill groaned. “I can't stand up straight…"

Dr. Gray circled around him, the mouse prodding at his hips, spine, and rump with a curious expression before he said, “That was quite a pounding you took. You'll probably be walking funny for the next week at least, but you'll be alright."

“A week, huh?" Gabe said with a smirk. “Why don't you schedule us another donation for next weekend then, when this little guy's back in shape?"

Quill just gave a thumbs up. “It's a date," he said.

Waving goodbye to Dr. Gray, the two cats wandered back to their car, with Gabe carrying a self-satisfied swagger in his step, and Quill the telltale waddle of a well-fucked ass.

“Well, there's our good deed for the day," Quill said as he opened his door, carefully bending to clamber inside the car.

“The day?" Gabe said as he slid into the driver's seat. “Not so fast, babe. Your ass might be out of order, but I think I could go for some roadhead on the way home."

“Wait! What?" Quill spluttered. But before he could say anymore, Gabe turned the key with one hand and the engine roared to life, and the other, he grabbed Quill's head, the green cat giving a yelp as he was shoved into his boyfriend's crotch, his massive horsecock crammed down his throat with a mutual moan as they pulled out of the JizzLabs parking lot together.
