#2 of Stable Love

After absorbing the explosive fallout from Apollo's change, Darrin has to figure out what's happening with the Braverman horses. Before he can get too far into his investigation, though, he finds Achilles the Cleveland Bay stallion has an even bigger surprise in store for him! The overworked stable hand looks like he's got a very long day ahead of him!

"What? I'm...fine." Darrin coughed once as he came to. His throat was sore and sticky. His chest and hips ached. His clothes felt like six inches of mud had caked dry on them, heavy and cold.

Then the memory of what had happened came to him in a bolt of realization. He froze, turning to stare at Roanoke. His pet was holding his shoulders in thick, paw-like hands. The familiar boxy muzzle was just inches from his face, tongue lolling, his panting breath drawing attention to a bodybuilder-thick neck spreading out to a pair of humanoid shoulders.

"What happened?" Darrin tried to stand. The world tilted enough to let him know that wasn't a good idea yet. "How did you...?"

Roanoke whined, a high-pitched sound that shouldn't have come from a creature that looked like it outweighed him by a hundred pounds or more. "I ate some of the food, boss. I'm sorry. But look! I can take care of you now!"

"I'm so relieved you're OK!" Apollo's voice broke in, booming all around them. "I was so worried. I thought I might have broken you!"

Darrin rolled his head back to stare at the stallion, who had been sitting awkwardly on his haunches. Even hunched in that position, the pointed roof of the barn barely reached his ribcage. If he stood, he probably could have stepped over it. Apollo had to have been at least 70 feet tall, maybe more; he was as powerfully built as ever, but graceful save for a cock that looked oversized even for him.

Darrin chuckled, and then broke out laughing. In a situation this insane, the only rational response was to go crazy.

He clutched Roanoke's arm as the dog helped him to his feet. The weight of the horse's seed bore down on his clothes, and he smelled the stallion's musk hopelessly ingrained in his skin and hair. "I...I think I might be having a nervous breakdown."

Roanoke gave a short whimper and helped walk his master to a seat on his porch. The house, thankfully, was still intact for now. "No, boss, no nervous breakdown here. It's more of a miracle, isn't it? Something amazing happened to the both of us!"

Apollo shifted carefully, placing his hands carefully in the yard and then sprawling out on his stomach. Nonetheless, the house rattled its complaint. The front yard was filled with the horse's head and shoulders. "I think the feed had something to do with it. Once I started eating it, it felt...like I could think for the first time. My head just got clearer and clearer, and then my body started changing."

Roanoke nodded enthusiastically. "Me too! I suddenly knew what...what words meant! I had no idea there could be so many! It's amazing!"

Darrin tried to ignore the sight of Roanoke's tip sliding out of its sheath. "I...don't know if amazing is the word. It's impossible. This...this shouldn't be happening."

"Well...yeah." Roanoke's ears swept back for a half-second before coming up again. "But it is happening! And I'm really glad I can tell you how much I love you in ways that you'll understand!"

Apollo rumbled in agreement. "Our languages aren't nearly so complicated. It can be hard to say what you really mean. But I love you too."

Darrin found himself touched in spite of the weirdness of the situation. "You guys...I knew just what you meant this whole time. I love you both, too. Very much."

Roanoke's grin flashed wide enough to show shockingly-large fangs. His tail wagged behind him, audibly whipping through the air. "Thank you, boss! That means a lot!"

"Mmm. You're welcome." The rush of adrenaline and perhaps the numbing effect of shock were finally wearing off. Darrin felt his heart return to something approaching a steady beat again, and he could organize his thoughts in a somewhat coherent fashion. OK, so this shouldn't be happening, but clearly it was anyway. There was an enormous dog-man panting inches away from his face, and an impossibly huge horse-man filled the entirety of his front yard. And the path behind it. And crushed the fence boxing off the pasture behind it...

His heart started to thud in his chest again, and he forced himself to relax. One problem at a time, he told himself. He had to deal with what was right in front of him for now.

"OK, you two." Darrin stood up and winced at the ache setting in to his body already. His clothes cracked, flakes of dried seed falling to the concrete of his porch. "I need to get into some fresh jeans, take a shower, then check on the other two horses."

"I don't think you'll need to check on us after all." A strange voice rumbled from somewhere behind Apollo's bulk. One of the thoroughbred's ears swiveled back, and his long muzzle followed a second afterward. He shifted to lie on his side, the ground rumbling from the displacement of his tonnage, and revealed another bipedal horse-man. This one was instantly recognizable to Darrin. A short, bright bay coat covered him, doing little to soften the hard edges of heavy muscle or hide the rounded swell of his stomach. His shoulders were broad and strong, his neck was long and powerful, and his legs were already thick with might; they rippled as huge black hooves carried the horse forward. The stallion's forearms and ankles darkened to a glossy black that matched the mane cascading around his shoulders. Familiar flecks of grey caught the sunlight between the horse's ears and in the shorter fur of his muzzle.

"Achilles?" Darrin's heart leapt. His stomach also sank. Already he was thinking about Atlas and what the Clydesdale would be like; hopefully Apollo and Achilles would be able to calm him down. Almost reflexively, he glanced at the Cleveland Bay stallion's sheath and saw it twitching visibly, the shaft inside pulsing rhythmically. It was growing larger against his stomach, balls already bigger than grapefruits, rolling full and round over his massive thighs.

Achilles smiled, the expression feeling more peaceful and natural to Darrin than it did when Apollo was first changing. Maybe he was getting used to the odd combination of their facial features already. "Yes, Darrin. It's so very good to see you."

Darrin straightened as Roanoke moved in front of him. He knew the Shepherd had a tendency to be protective, but it was much more impressive when he was seven...eight feet tall. Jesus, he was still growing. He felt a well of gratitude rise up inside of him, but also a nervousness he wasn't used to. He was used to working with large animals, but this...this was something entirely different. Even before, he was reasonably sure he was in charge of the horses. Now, everything was out of his control.

Achilles walked around Apollo towards the porch. The Bay stallion was already noticeably larger than the human, but he grew bigger even as he approached. By the time he had navigated the huge bulk of his stable-mate and stood in front of Roanoke, he was tall enough to see into the second-floor window of the house. The way his hooves churned the grass even as he stood still signaled he was still growing, and visibly fast.

"I know this must be a shock for you." Achilles' voice was a rumbling roll, thrumming in Darrin's chest like a big cat's purr. "I don't know why this is happening, but I can assure you I'm glad it is. We can finally speak to you in a way that leaves no room for doubt."

Darrin nodded, tilting his head back as the horse's shadow deepened around him. "It's not the speaking part I'm worried about; it's the size. How are we going to care for you? Where are you going to live? How can we keep you now?"

Achilles sank to one knee, the thump shaking the windows behind Darrin. His expansion seemed to push his physique into much more powerful territory, muscles swelling under his pelt. Every breath the horse took pushed his chest deeper and wider. The hoof that was still planted firmly on the ground was about the width of the fountain in front of the Braverman mansion, and widening.

"Those are all excellent questions, sir. No matter what happens here today, I would like to stay with you." The horse's dark brown eyes stared at him, calm and thoughtful. "Would you like to stay with us?"

Darrin nodded immediately. "Of course, but it's not up to me."

Achilles smiled. "I don't think it's entirely up to the Bravermans, either. We're sentient beings now. We shouldn't be considered the property of someone else. We should have a say in what we do and where we stay. Just like you."

The horse's voice deepened powerfully while he spoke. His body grew until it nearly filled the space between Darrin and Apollo. Roanoke stepped back with a quiet whine, bumping his head on the awning. The cool morning air was banished from the front yard, replaced with warm, humid, musk-scented haze. Darrin had trouble concentrating on the content of the horse's argument, but it was tough to argue what was there. He had no idea how it would play in a court of law, though - this was completely uncharted territory.

A sudden rumbling nicker boomed from the horse's chest as he tossed back his head. The stallion's nostrils flared before that already gigantic body shuddered and grew quickly. One enormous black hoof churned up the ground as it approached Darrin and Roanoke, who yelped and flattened himself against the front door. Achilles cramped the space in the yard by now, his short thick pelt rippling over muscles that were growing steadily larger. The house shook ominously when the horse moved.

"Maybe we should go somewhere with a bit more open space." Achilles appeared to be panting as he rose to his hooves. Darrin got dizzy tilting his head back to follow the horse's ascent. He had to be 50 feet tall now, approaching Apollo's size and growing fast.

"Yeah, let's head out to the pasture!" The thoroughbred practically jumped to his hooves, the impact forcing Darrin to stumble against the strong frame of his dog. "There's plenty of room to run around there!"

Achilles whickered as Apollo stomped off, sending birds panicking out of the trees of the distant forest. He watched Apollo disappear around the side of the barn, the rhythmic tremors of his hooves lessening bit by bit. After a moment he turned towards Darrin, leaning over the bulk of his chest to peer at the human partially hidden beneath the porch. "I think it would be best to carry you, Darrin. It's easier, and it's safer."

Darrin's heart began to beat harder in his chest all over again, and his pants tightened uncomfortably. He wasn't sure this was a good situation. He wasn't sure if he should be allowing the horses to roam through the property. Who knows how much damage they could cause? Who knows what effect they might have on the plants and animals around them? It would be better to ride out this latest growth spurt as close to the stables as could be managed, just to keep everything contained.

"OK," he said. He knew he wouldn't have it in him to resist the slightest bit of questioning.

Achilles nodded and moved as quickly and carefully as he could. One enormous hand wrapped itself around Darrin, blocking his view of everything else. Thick horsehide surrounded him on all sides, smooth and warm, stretching thicker around his body.

"Please tell me if I hold you too tightly. I'm...not used to having hands." The Bay stallion squeezed his small cargo gently. The flesh gave only slightly around Darrin's body, expanding even through that small motion.

Darrin gasped as he was lifted off his feet for the second time today. His vision was filled with the top of Achilles' fist, with the visibly stretching wrist and forearm just beyond it. "Uh, sure."

"Thank you." The stallion's voice thundered through the little human. Achilles lifted Darrin several stories in the span of a few heartbeats as he rose and turned towards the pasture. He had put on more than a dozen feet in no time at all, and even though he stepped carefully towards the barn it was clear that he was distracted. Darrin could only imagine what the giant must be feeling, having a strange body and an even stranger awareness of it all of a sudden. Not only that, but it was changing constantly, flooding his brain with sensations that he - or anything else for that matter - had ever felt before. Who knew how much Achilles was being forced to process in such a short amount of time?

A startled bark drew his attention down towards the ground, which was surprisingly further away than he thought it should be. He saw Roanoke running frantically for the stables. The wood was shuddering violently as Apollo returned; Darrin wasn't sure how much more of this abuse it would be able to take. The thoroughbred scooped up the German Shepherd without missing a beat, nearly taking out the front of the structure in doing so. Roanoke disappeared beneath the stallion's great hands as Apollo held the dog against his chest.

"We should get to the pasture already, Achilles. You're going to break something if you stay here much longer." Apollo stood next to the Bay stallion, his muzzle looming over Darrin. Darrin could see little more in front of him than the vast wall of Apollo's chest, enormous pecs looking even larger compared to the horse's sturdy hands. Darrin's pants were uncomfortably tight; even though the view was breathtaking, he felt vaguely ashamed at the realization that he found the horses so undeniably attractive.

"I'm coming, Apollo. Patience!" Achilles spoke quietly, but at his height the sound of his voice was still a shock. Darrin could feel it shake him as he sunk further into the giant's fist, every syllable seeming louder. The Bay had outgrown the thoroughbred, his ears rising 85 feet into the air or so. Every bit of him was gigantic, and Darrin could almost see cable-thick muscles and tendons stretching under the horse's fur. "I...I just need a moment. This feels so good."

Even as the girth of the finger in front of him prevented him from seeing much of the ground at the horse's hooves, Darrin heard the boom when they landed next to the stable. It was startlingly explosive. Darrin tried to look down to see if the structure had been damaged, but his view below was dominated by an erection that looked to be the size of a tree, jutting out from strong, broad hips. It bobbed as Achilles stepped forward, the shadow waving over the stables as the horse moved past it. The next step carried him even further, a good bit away from the now surely-damaged building. His stride lengthened with every step, the hoof outgrowing the print it had made almost as soon as the tremors died down. Achilles had to make sure he was well planted before he moved again. The growth and the arousal had to have been driving him crazy.

The thunderous passage of the horse grew more distant but louder and more distinct at the same time. The digits around Darrin grew thicker and the leather coating them became rougher, less pliable. The spaces between them widened until Achilles remembered to keep his fist tight so the human didn't slip or fall. The stallion was simply gargantuan now. Darrin looked around at those fingers and tried not to think about how a simple squeeze would be enough to crush him. The power of the stallion seemed endless, but he still took great pains to be as gentle as possible.

In the short time it took to walk to the main pasture, Achilles had grown over a hundred feet tall. Darrin's view was dominated by the stallion's amazing body, the finger alone nearly double the size it was when he was hoisted up. It was growing thicker than his shoulders, longer than he was tall. The outside edge of it was coated in a carpet of coarse, short fur that almost felt like velvet, while the inside was a rippling leather expanse pressed tight around him. It felt so strange to feel the horse stretching against his chest, but the sensation against his covered erection was more pleasant than he was prepared to admit. Darrin planted his feet on the edge of the stallion's middle finger and tried to wriggle higher so that his waist was above the hole that Achilles had made for him.

"Be careful!" Achilles thundered from above, tilting his fist to tumble Darrin backwards. He huffed as he tumbled back into the growing expanse of the horse's open palm, only stopping once he was on his back. He looked up to see the breathtaking sight of the stallion filling the sky above him. His shaft throbbed painfully hard, his zipper biting into the skin through his underwear. He wasn't sure if Achilles would even know how aroused he was, or if the size difference between them gave him some small measure of privacy. The immense horse snorted and grinned as he watched, and Darrin knew that Achilles noticed something at least.

Darrin was lifted towards that gigantic muzzle for a closer look. The boxy edge expanded past his field of vision as Achilles leaned in close and sniffed. Cave-like nostrils flared, and the rush of air actually scooted him closer along that palm. The rumble that followed shook Darrin's bones. He wasn't sure what it meant until he saw the stallion's lips pull back into a grin, holding his hand further back so that he could be seen.

"It smells like you appreciate the view from up here." The horse's voice was purring thunder, shocking yet calm. "I'm glad you do. I could lower you down for a closer look, but that might mean we would end up...playing together. Is that all right?"

Darrin stared at one chestnut-brown eye, his heart pounding in his chest as he considered the proposition. Of course it would be all right...wouldn't it? The experience with Apollo was overwhelming enough, but with Achilles there was a serious chance he would be hurt. The monster was already one-third taller than his stablemate and showed no signs of stopping. Every inhale of the beast swelled out his chest a little more, and Darrin could feel himself rising higher on a thickening, stretching plain of horse hide. Every time he looked at Achilles' face, his muzzle was a little broader and those clear, concerned eyes regarded him from a greater distance. His neck grew thicker and more muscular all the time, almost squat with power. The overall effect was a powerful mixture of lust and panic. He shouldn't, but he had to.

"I think so." He looked around at the palm he was on, letting himself feel as small as he was. The knot in his stomach tugged his shoulders until they hunched. "But you'll be careful, right?"

Achilles smiled in that reassuring and frightening way. "Of course I will, Darrin. Hit me with your fist as hard as you can three times if I'm doing something you don't like. Can you do that now, so I know what it feels like?"

Darrin nodded and thumped the base of that broad digit three times. Each time he did it, the leathery surface was noticeably thicker and more durable. Even still, Achilles nickered his approval and nodded, mane shaking with the motion. It was thick enough to get lost in now, coarse, long strands of hair about as thick as his own fingers. The silver threads on his muzzle were more noticeable now, though at the moment Achilles didn't seem that old at all.

"Excellent. I'm going to lower you down to my cock now. I...don't know what this will be like for you, but I want you to know that I have every intention of keeping you safe. You might want to remove your clothes, just so they don't get more messy than they already are." Achilles spoke slowly and with great concentration, his nostrils flared. His shoulders practically heaved with his breath; he was approaching the size of a skyscraper now, with a cock that was somehow still oversized for his frame.

"It's too late for that, friend, but I guess I'd better." Darrin grinned, forcing himself to look away from the titan filling his vision and unbuttoning his shirt instead. The fabric was already stiff with the dried remnants of Apollo's flood, and it took him extra time to slip the flannel off his shoulders. By the time he did, Achilles was beginning to lower the hand that held him.

The stallion's broad and graceful neck immediately widened into an explosion of shoulders, each bulging with incredible strength. His chest was almost cartoonishly broad, barreled to an extreme that seemed impossible in real life. His arms were forced away from his torso by the size of his pectoral and lat muscles as well as the hills of his biceps. They were unnaturally large, peaked with a vein that reminded Darrin of a firehose snaking under the giant's pelt. Thick nipples the width of refrigerators jutted from the bottom of his chest, perking out of the short, close thicket of his hide.

Achilles grew the entire time, those fingers rising all around Darrin, that chest swelling thicker and broader with every breath. His brown fur soaked up the sunlight as if it was fueling his expansion; Darrin would not have been surprised if he learned it was. As soon as the Bay's nipples rose into view, another shadow threw Darrin into an even deeper gloom.

He turned to see the horse's immense shaft towering in front of him, more than long enough for the broad flare to throb right in front of Achilles' nostrils. It shuddered visibly with his pulse, widening impossibly thicker, growing feet higher, blood rushing to feed the monster with every heartbeat. Darrin marveled. It was too big to be believed, even considering the immense size of the horse it belonged to. He had to wonder if Achilles was light-headed between the constantly rising altitude and the sheer amount of blood devoted to keeping that insane erection engorged.

"Are your clothes off?" The stallion's voice shook the world around him, a boom of thunder that echoed in the distant trees.

"Almost!" Darrin was shocked out of his daze and remembered he still had to take off his pants and shoes. He worked as quickly as he could, wrinkling his nose at the way they crunched whenever he tried to bend them. It took him nearly a minute before he was naked, his stiff clothing sprawled out on the rough surface of Achilles' palm. "There."

He was being lowered the entire time, the shadow around him deepening as he descended deeper between the wall of the horse's abdomen and the jutting tower of his cock. Achilles' scent was much thicker here, rolling with heat, and Darrin was dominated by it to the point that his eyes burned and his head spun. He gasped for air as he turned his head towards abdominal muscles each the size of a toolshed, then the too-large shaft thumping with an almost-audible rumble. When his hand finally lowered to the root of that monster erection, Achilles tilted his hand so that his knuckles rested against it. Gravity sent Darrin sliding down towards the edge of the horse's palm until his feet brushed the thick, overwhelmed hide of the giant's sheath.

"Good." The stallion's voice was a deific roll of thunder rumbling thick enough to force Darrin's teeth to chatter. "I think you can stand up where you are for a minute, but let me know if you're worried about falling."

Darrin did his best not to even think about falling. He caught sight of his clothes sliding, then tumbling out of Achilles' palm. They landed in the thicket of coarse fur and folds, but every movement shifted them closer to the edge of it. Darrin watched, but didn't even attempt to grab them. If they fell, they fell - he wasn't interested in falling after them.

He focused instead on the statuesque body looming all around him. The muscles of the stallion's lean belly rolled and flexed with his movements, and the cock loomed on the other side. Its thickness rivaled the torso he leaned against, a living wall of flesh that thumped and shifted right in front of him. The movement was almost hypnotic, skin stretching around the sheer size of that member, blood visibly pulsing to supply its immensity with blood. For several moments, Darrin forgot that he was supposed to be trying to keep his balance. He simply stared upwards, the flared head of that member slightly higher than Achilles' own.

Darrin was brushed gingerly by a massive thumb. He startled out of his trance, putting a hand reflexively on the tip of the digit. It was thick enough to brush his knees and chest at the same time, with the hardened hoof as impenetrable as marble at this size. The giant horse flexed, rolling his stomach so that the little man was practically forced against the base of his shaft. Darrin spread his arms, and almost immediately he was buried under the rough tip of a thumb. He felt a gentle pressure that was still more than enough to force him against the musky surface of the cock before him. It was barely any effort for Achilles at all; it only served to remind him how much the horse was holding back, how easily he could be crushed in a moment's carelessness.

Despite the fact that realization made Darrin's heart leap into his throat, his erection was as achingly hard as ever. He had known Achilles a long time, and the stallion was nothing if not gentle. Even when he was only a thousand pounds, he seemed mindful of his size and weight - careful around animals smaller than he was. There was no concern that he would abandon that, even though his power had been enhanced to an insane degree.

"Do you trust me, Darrin." That mammoth thumb gently slid the man a little higher along that cock; Achilles leaned forward to see the speck of a human being over his own pectorals.

"I do!" Darrin called without hesitation. His body was pressed flush against the stallion's cock, his own erection fit to burst. It surprised him that he was able to say it so emphatically.

Achilles smiled, the smallest twitch of his finger pushing Darrin into the slight give of his cock. "Excellent. I can feel you now. Isn't that...amazing? I can feel that you're enjoying this. I hope you'll enjoy what comes next, too. If you don't, you know what to do."

Darrin thumped three times against the side of Achilles' thumb.

The horse whickered his approval, nostrils flaring as he wrapped his fingers around what he could of his own shaft. "That's right. I love you, Darrin."

The man was lifted beneath that thumb, the thick digit pushing against his rear and the small of his back. His own shaft ground against the stallion's burning skin, the careful pressure enough to take his breath away. None of it was uncomfortable, but it was strange. The horse's scent burned his nostrils and made his head spin. He was traveling stories higher into the air, body stroked against an immense erection. It was the strangest, kinkiest thing he had ever done.

The surface of the stallion's member was strange. The mottled flesh wrapped around his body as he was slid against it, but he could feel it stretch whenever Achilles flexed it or his heart beat. He could feel the pulse pound him back into the stallion's thumb-tip, reminding him all over again how impossible this was. Darrin closed his eyes and tried to breathe slower; not for the first time today, he was in danger of being overwhelmed.

At this size, he could feel every ripple of flesh, bulge and imperfection of the cock burning into him. His had bumped against the flare as he traveled to the tip, opening his eyes and looking slightly down at Achilles' face. The stallion had to reach up and out just to get to that point; his eyes were closed in concentration, or lust, and his nostrils were flared. This is the closest the horse had ever come to rutting.

Darrin reached up and touched one of the bulbs that lined the edge of Achilles' flare. The world shuddered in response. He could feel the tons of arousal strain in response to the touch, and his own erection throbbed as well. His breath was caught short by the unexpected flood of his excitement, and he watched the flare visibly spread above his head as he was taken back down.

Darrin groaned breathlessly, his hands kneading the tower of flesh as sunk lower in his controlled descent. He grit his teeth as he was pressed firmly against the medial ring, the sensation nearly pushing him past his own climax. By the time he recovered enough to open his eyes, the mostly pink flesh had darkened to a grey-black, and the air had darkened under the weight of the horse's shadow. Heat and musk blasted him from all sides, thick enough to make his eyes water and force a cough from his throat. Even that was a delight to him.

The world was practically spinning by the time he was brought back to the root. His toes curled against the thick, stretched skin of the horse's sheath and his hips ground against a vein that was thicker around than one of his thighs. Darrin forgot that he would be noticed until the rumbling chuckle of the horse let him know he'd been caught. He blushed, hiding his face for just a moment. The numbness of shock was slowly giving way to excitement, even eagerness. He could never have admitted it before, but this was almost a dream come true. It was insane, not something he ever thought could be possible, but here he was, living it out.

A soundquake whinny shook Darrin as he was lifted back towards Achilles' tip a little more quickly. He could barely catch his breath in time to grind against the medial ring, and he had barely recovered from the sensation of that before his head was pushed directly under the flaring tip. The top of his scalp sunk into the sensitive flesh, and he squeezed his eyes shut as he felt the gargantuan member thicken against him, swelling to the point that the stallion had trouble holding it in both hands. Darrin shuddered and grit his teeth again, trying to stave it off, but the intense sensations, the power on display, the addled senses of his overloaded brain - they were just too much.

His fingers dug into the flesh of Achilles' cock as he climaxed. Every muscle in his body tensed; it felt like his cum was being ripped out of him, he gushed so hard. His dick thumped between his body and the horse's, and even as he was pulled down he kept gushing. His breath was stolen again and again with each shot, and he barely had time to gasp a high whine before he was shaking all over again. Being rolled over a vein or ridge only stimulated him further; by the time he was brought back to the base he thought he might pass out from being overstimulated.

Darrin didn't remember much of what happened for a few minutes after that. He remembered the persistent heat and body-shaking pulse. He remembered being slid along a mountain of flesh and increasingly brushed against the top of a flare as big as a satellite dish. The constant stimulation and overwhelming musk kept his brain addled, and his limbs weak and tingling as he slowly recovered from the most intense orgasm he ever had. He still tried to knead and rub Achilles' member as much as he could, saving his energy for when he was rubbed along the broad, flat surface of that flared tip. The entire time his own cock remained stubbornly hard, teased and ground again and again.

He could barely hear the nickers of encouragement booming down to him over the sound of his own heartbeat in his ears, but he could feel the rumble of it in his bones. When he was brought to the tip he kissed the engorged flesh and squeezed whatever he could as he swirled around the edge of it. He pushed his face into the yawning chasm of Achilles' slit when brought to it, and a roaring neigh shook the sky around him. Whenever he could see the face of the stallion, his eyes were closed and his nostrils flared. Every once in a while, he could hear a hoof slam the earth dozens of feet below him or the bull-roar sound of his mane tossing. The Bay stallion was giving in to his lust, bit by bit.

Achilles' climax took them both by surprise. One moment, the horse was rolling Darrin towards his slit with a fingertip, and the next the flare rose and swelled while the stallion's oversized sac thumped against his hips. The sound that Achilles made was a roar that rattled the inadequate fences around him, and the stallion pressed Darrin down against that bulging cock. Just a few feet away, a geyser of seed erupted - thousands of gallons of thick, white cream rocketed in a column more than a yard wide, just the edge of it instantly coating the little man with the splatter.

The sound of so much fluid roaring at such a high volume, combined with the ear-splitting roar of the titanic horse, filled Darrin with an almost-primal fear. He snapped to, suddenly aware of Achilles' insane size and power, aware that a small lake of seed was gushing into the air and falling back down to flood the pasture below and likely a good deal beyond it. He stared in awe from where he was pinned, gasping as the tip of that member rose beneath him, pushing him painfully into the horse's finger. By now his flare was coated with seed, the skin slick and glistening.

Darrin clutched the stretched skin as tightly as he could in the gap between shots. That first blast felt like an eternity, and he blinked through the haze to see the seed raining down in a cloudburst when the second eruption started. His ears rung with the sound of it, a small spray splashing towards him. He was coated instantly, the world going white as he lost all sensation. He could have been blasted out from beneath the giant's finger and he would never know. Fear gripped his heart, forcing it into a jackhammer beat. Somewhere through the persistent roar in his ears, he could hear the sounds of impact all around him. Tons of seed landed on the stallion's muzzle, shoulders and chest, but that might as well have been miles away.

The weight of Achilles' cum finally glued him in place...somewhere. The thickness of it made moving his limbs an effort, and his body had no idea how to register the temperature. At first, it felt almost freezing; then it seared him. He squirmed under its weight, lifting himself to his knees with some effort. Achilles snorted, a thundering boom announcing his third geyser. A solid column of seed shot high above the meadow, breaking apart to create several lakes on and around the colossus. Darrin was splashed again, knocked on his back and off his breath, recovering in that heartbeat that broke up the next surge.

At least a dozen blasts rocketed through Achilles' straining erection this way, more than a minute passing before his climax began to subside. Darrin was flattened several times more, and by the time the stallion was able to relax his mane, shoulders, chest and shaft were completely coated in a sticky mess of his own making. Even considering the horse's great size, it seemed impossible that he could produce so much. Darrin couldn't imagine the scene on the ground below; the meadow must have been flooded, and it would be a minor miracle if any of the fences had survived.

The thunderous howl of Achilles' whinnying steadily shrunk to the lesser rumble of quick-panting breaths. The giant stallion plucked him gracelessly from his perch atop the deflating member; briefly, Darrin's world was unyielding horsehide, twin walls of thumb and forefinger. The grip was gentle for all of that; he didn't need to struggle for breath before the digits opened and he went tumbling down the length of a finger and back into vast, black plain of his horse's palm.

Between the thorough coating and rapid changes in position, Darrin needed a minute or two to reorient himself. When the world stopped spinning and his heart no longer thundered in his ears, he realized he was being held against Achilles' chest, that short thick pelt glistening with the shower he had just given himself. A flat-toothed, almost goofy grin was nestled between those mammoth pecs, his graceful neck disappeared into the insane size of his shoulders. Achilles was unquestionably bigger than any life-long bodybuilder by proportion, almost burdened with strength. But those deep, dark brown eyes were as friendly as ever, laughing and gentle. Darrin stared up and found himself smiling, that nervous tension in his chest bursting open; it was replaced by a loving warmth that flowed all through him.

The hand shifted, lifting Darrin closer. Thick lips opened and a broad tongue rolled free between building-sized teeth. It took Darrin a moment to realize that it had met the leather of Achilles' palm, and another moment more to realize that it was rapidly rolling right for him. He managed a surprised yelp before he was flat on his back and coated by the heavy, warm muscle. He gasped at the sensation, a riot of emotions warring for dominance inside his head. His shaft exploded before he could sort himself out, an almost painful intensity wracking his body as his erection pulsed where it had been trapped against his stomach.

Achilles slid over him entirely, his head forced sideways as it was pushed into the thicker surface of the horse's palm. He was pushed along towards the fingers as a wave of pressure flicked over his crotch, then his chest, then his head, and lifted. He was left spread eagle and panting under the shade of Achilles' middle finger, the fireworks of his second orgasm clearing from his vision. It felt like he couldn't quite catch his breath. He shivered in his disorientation; was he too hot or too cold? It took another couple of minutes before he could feel his arms and legs again, the tingle of blood rushing to his extremities making him squirm.

"Are you OK?" Achilles boomed over him, muzzle stretching out from between the pecs they were stuffed between. Darrin flinched; even though the horse was lowering his voice, the volume was still enough to make his ears ring for a second or two.

He nodded as he recovered, forcing himself into a sitting position. "I'm OK. That was just...the most intense sexual experience I ever had."

An amused nicker rattled through Darrin. "That was the most intense one for me, too." The horse's snout pushed forward, filling the human's vision. "Thank you, Darrin."

Darrin was flattened again beneath Achilles' kiss, his body introduced to another strange sensation. The 'soft' velvet of the stallion's lips brushed all over him, twin walls of rumbling skin pressing him back into the smooth surface of a single finger. His shaft thumped back to life, and Darrin planted his hands with a small whimper. He wasn't sure how much more of this he could take.

The kiss was broken a moment or two after that; Darrin patted the monstrous horse's chin as high as he could reach. "You're...you're welcome," he panted. "It's hard to believe you could be so gentle and nimble."

"It surprised me, too. I'm not sure how I'm able to manipulate someone so small so easily, but I'm glad that I am." Achilles' head lifted and looked around. Darrin felt himself lowering as the horse picked a relatively dry spot in the meadow to sit. For several moments, the sound of the tortured, flooded earth being broken and reshaped under the stallion's tonnage was all Darrin could hear. He couldn't resist the urge to peek over the edge of the palm. The view was breathtaking, with Achilles' brown fur taking up most of his vision. The ground was still a shocking distance away. "It will...take some getting used to, being this big."

"For all of us." Darrin took a deep breath and settled again, away from the edge. "I have no idea how the Bravermans are going to react to any of this."

"What makes you think their reaction matters to the outcome of this situation? I am sure we'll come to an arrangement that benefits both of us. The alternatives wouldn't be good for anyone." Achilles spoke gently and evenly, but there was no mistaking the confident threat lying behind those words.

"I'm...not sure we should think that way, Achilles." The now-familiar rumble of Apollo boomed nearby, below his perch. "I wouldn't be surprised if they found a way to turn us back into normal horses, once they found out how this happened in the first place."

Achilles moved his hand from his chest to his side so Darren could see the other horse. Apollo was standing proud and tall, looking as statuesque as ever, but even at his height he couldn't look the Chesapeake Bay stallion in the eye even though Achilles was sitting down. It brought home just how big the horse had become - more than twice the size of his stablemate who himself towered over the barn they had shared. Darren's head spun all over again. He was lost in a landscape of animal masculinity.

"Maybe," Achilles nodded, shifting to face Apollo. "But I don't think anyone would. We're intelligent beings, are we not? The Bravermans are good people. I truly believe that. But if they won't look after our best interests, we do have an advocate in Darren. Don't we, little man? You will protect us, won't you?"

The tone of Achilles' thundering made it difficult for Darren to know whether he was being mocked or not. Two sets of huge brown eyes turned in his direction, and he became painfully aware that he was completely naked and covered in horse cum. It took him a moment to speak in a way that carried any strength at all. "I'm...not sure what I could do, but yes. I'll do what I can."

"Why, you can navigate the world of men, of course!" The plain of Achilles' hand shifted, forcing Darren to stumble down a sudden incline towards the middle of his palm. The half of the sky that wasn't taken up by the Bay's muzzle was now filled with Apollo's. "You would be able to convince the others through...some sort of law, I'm sure. Or you could find other humans who would know what to do."

Darrin was not so sure. "Well...we'll just have to see what happens. There's no way we can keep the two of you hidden, so we'll have to deal with this sooner rather than later."

"Two?" Apollo flicked an ear, one eye glancing off in the direction of the barn. "Your dog has changed, too. And the sound coming from the barn tells me that Atlas is going to be up here with us soon..."
