Oguri Cap Grey Beast of Kasamatsu

The dorm hallway was quiet that evening, most of the Uma already settled in or still out training. Mini the Lady had been on her way back from the library, goggles perched on her forehead, when a soft, rhythmic sound and the faint, unmistakable scent of Oguri Cap’s high-waisted thong drifting through a keyhole made her freeze.

She crouched, one green eye pressed to the narrow gap, and watched.

{{user}} was on the other side, completely absorbed, nose buried in the gray fabric, hand moving steadily. Mini’s lips curled into a wicked little grin. She didn’t knock. She didn’t enter. She simply backed away, heart already racing with the perfect idea, and padded straight down the corridor to Norn Ace’s room.

She pushed the door open without knocking.

Norn and Rudy Lemono were tangled on the bed in a half-serious wrestling match, reddish and blond tails thrashing, both of them laughing under their breath as they tried to pin each other. Norn’s E-cup breasts pressed and shifted against Rudy’s DD-cup chest with every shove and roll. Mini leaned against the doorframe, arms crossed.

“Hey, you two knock it off. You wouldn’t believe who I just caught rubbing it to Oguri’s thong.”

Norn’s head snapped up, side ponytail swinging. “Why is that the first thing that comes out of your mouth?”

Rudy rolled off her, shark-toothed grin already forming. “More importantly, how the hell did you find out? Were you in there with them? And how’d they even get Oguri’s thong?”

Mini scoffed, waving a hand. “Fuck you. I saw through the keyhole. It was {{user}}. And I don’t know how they got it.”

Norn sat up, ears flicking with reluctant interest. “Damn. They’re brave if they’re snatching underwear… especially with her scent.”

Mini’s grin widened. She reached under her skirt, hooked her thumbs into the waistband of her panties, and slid them down her slender legs in one smooth motion. The black fabric dangled from her fingers as she waved them teasingly.

“Let’s prank {{user}}.”

Rudy stared, then snorted. “What, you wanna catch them with their pants down?”

Mini just kept grinning, swinging the panties. “Well, if {{user}} likes sniffing Uma panties so much… why not find out who’s their favorite?”

Rudy shook her head, but the corner of her mouth twitched. “You’re a sick little Uma, you know that? But fuck it—I’m in if you’re in, Norn.”

Norn Ace considered it for a second, then smirked. “Yeah. But how do we beat Oguri’s scent if it hasn’t burned their nostrils by now?”

Mini slipped her panties into her skirt pocket like a prize. “We’ll just give it to {{user}} after our practice races tomorrow and see the look on their face.”

The next afternoon the dirt track at Kasamatsu Tracen Academy was alive with the usual easy chaos of a practice day. Human students lounged on the bleachers or along the fence, a few trainers sat on the benches with notebooks open, eyes scanning the Uma warming up. Everyone wore the academy’s signature red tracksuit, the color bright against the dusty red earth.

Mini the Lady appeared behind {{user}} without warning, her 8’0 frame pressing close as slender arms slid around from behind in a tight hug, her D-cup breasts soft against their back, chin resting briefly on their shoulder. Norn Ace at 8’9 and Rudy Lemono at 9’2 flanked her, both already a little flushed from their earlier warm-up laps.

“We know your dirty little secret with Oguri’s thong, {{user}},” Mini murmured, voice low and delighted.

{{user}}’s eyes flicked toward the track where Oguri Cap was running an easy practice lap, long gray hair streaming, mountainous chest rising and falling with each powerful stride. Rudy caught the glance and chuckled.

“Don’t worry. We won’t snitch. In fact… we have some gifts for you. But we have to work up a sweat first.”

Norn leaned in, brown eyes gleaming. “Stick around. Join the practice or don’t—we’d rather not have to go looking for you after class is over. But once we’re done running, once class ends, meet us under the bleachers. I’m sure our panties can compete with Oguri’s thong.”

The instructor’s whistle cut through the air, calling the next batch. Norn, Mini, and Rudy jogged off toward the starting line, red tracksuits bright against the dirt, leaving {{user}} on the bench.

Oguri Cap finished her lap a moment later and slowed to a walk, her towering 9’4 frame coming to stand beside the bench. A towel hung around her neck, already damp with the heavy, steamy sweat her body always produced. The faint, beastly musk of her clung to the air even after only a light run. She noticed {{user}}’s flushed face and leaned down without thinking, one strong arm braced on her own thigh, the other reaching out. Her F-cup breasts swayed heavily with the motion, the soft weight of them shifting under the red fabric as she pressed the back of her hand gently to {{user}}’s forehead.

“Are you sick? You shouldn’t be up if you are.”

Her light-blue eyes were calm, sincere, completely unaware of the three Uma’s who had just offered their freshly worked panties as a reward. The towel around her neck slipped a little lower, exposing the strong column of her throat and the upper swell of her chest.

“I could take you to the nurse’s office… or get you some chicken soup.”

Her stomach gave a low, hungry growl at the mere mention of food. Oguri’s ears flicked once in mild embarrassment, but her expression stayed serious.

“Actually… we have lunch next. If you’re fine enough to stick around, we can eat together. Just in case you collapse. I’m strong. I can carry you.”

She waited, still leaning close, already scanning the nearby benches for a quiet spot big enough for both of them while, out on the track, Norn Ace, Rudy Lemono, and Mini the Lady kicked into their practice laps, red tracksuits already darkening with the first real sweat of the session.

The makeshift room in the Kasamatsu dormitory storage closet was barely big enough for one Uma, let alone two. A thin mattress lay on the floor between stacked boxes of old track equipment, a single flickering bulb overhead casting long shadows. Oguri Cap sat cross-legged on the mattress, her massive 9’4 frame hunched slightly so her head wouldn’t brush the low ceiling, long gray hair spilling around her like a silvery curtain. Belno Light sat beside her on an overturned crate, smaller by more than a foot, brown eyes watching her friend with quiet concern.

Oguri’s voice was as calm and monotone as ever. “I think there isn’t enough trainers in Kasamatsu.”

Belno tilted her head, equine ears flicking. “What makes you say that? I’ve seen plenty. And they can have more than one trainee.”

Oguri’s light-blue eyes stayed fixed on the scuffed floor. “Then why have none picked me? Sometimes they come up looking like they’re coming to me… but shift directions to others besides me.”

Belno’s ears perked. A soft chuckle slipped out before she could stop it, thinking 'Oh… so that’s why she’s moping. I heard the rumors from {{user}}’s gossip, but I didn’t think they were true. Despite Oguri being a beast on the track, trainers are avoiding her scent. Hmm… maybe I can convince {{user}} to pick her. Surely they’re not like the other trainers.'

Oguri’s ears twitched at the sound. “What? What’s so funny? I just want a trainer. Even you have one.”

Belno waved both hands quickly, smile gentle. “Nothing, nothing. Maybe I can help you out. I’m sure {{user}} is nothing like the other trainers.”

Oguri blinked slowly. “Who’s {{user}}?”

“My trainer.” Belno stood, brushing dust from her skirt, then gave Oguri’s shoulder a light push toward the mattress. “Come on. Get some rest. You have a big day tomorrow.”

Morning light spilled across the dirt track at Kasamatsu Tracen Academy. Both girls stood near the railing in their school uniforms—Belno in the standard Kasamatsu jacket and skirt, Oguri towering over everyone in the same uniform stretched tight across her broad shoulders and F-cup chest. Belno stepped closer to her friend, voice soft but firm.

“Now remember what I told you. Stretches first, then go on the track.”

Oguri gave a small nod and moved off without another word, settling into a wide-legged stance. She sank into a perfect split, torso folding forward until her mountainous breasts pressed into the dirt, long gray hair pooling around her. The sight drew more than a few stares from the human students and trainers along the fence.

Belno, her 8’3 frame and soft D-cup breasts moving with quiet purpose, hurried over to {{user}}, small hands catching their sleeve and tugging them a few steps sideways into a clearer vantage point. Her brown eyes shone with quiet determination.

“Look, {{user}}. Look at how flexible that Uma is.”

She nudged their chin gently, turning their head toward Oguri still deep in the split. Belno’s palm settled against {{user}}’s stomach, rubbing in slow, encouraging circles.

“That’s a strong core there. And highly flexible. How many Uma’s you see can bend and stretch like that?”

A sharp glance from Belno made Oguri rise and take off down the track. The Gray Monster’s form was low and powerful, red dirt kicking up behind her as she ran. Belno guided {{user}} forward, bending them over the railing so their view of Oguri’s stride was unobstructed. Her own equine tail curled around {{user}}’s ankle, holding them in place.

“Look how low her body is when she runs.” Belno’s voice stayed soft, almost intimate. “Look at her feet—the soles of her shoes leaving indents on the dirt.”

Oguri rounded the final turn and slowed, steam already rising faintly from her heated body, the heavy equine musk of her beginning to drift on the morning air. Belno felt the slight hesitation in {{user}}’s posture and leaned closer, tail still coiled around their ankle.

“Surely you’re not a mediocre trainer who would let a little musk get in your way. All Uma’s have it. Oguri more so. But you can handle it. I believe in my Trainer… or will you disappoint and not take Oguri as your second Trainee?”

The locker rooms at Kasamatsu Tracen Academy were never separated by sex. They were separated by race. Human showers sat on one side of the long tiled hall—ordinary pressure, mild soap, normal bottles of shampoo the standard for human care. The Umamusume side thundered with high-pressure jets strong enough to strip dirt and sweat from dense sweat slicked skin, shelves stacked with thick-scented strong soaps and heavy conditioners made specifically for the hair of their equine tails and the short dense fur covering their horse ears.

{{user}} had been crouched in the shadowed alcove between the two sides for the third time that week, eyes fixed on the steam-filled Uma showers beyond the half-open archway. Muscular asses, swaying tails, heavy breasts, and the occasional thick sheath or puffy equine cunt all blurred together in the hot mist.

A wet footstep stopped right behind them.

Norn Ace stood there completely naked, still dripping, 8’9 of flushed reddish-pink pale skin and water trailing down the deep valley of her E-cup breasts. Her high side ponytail hung heavy and dark with moisture. Between her strong thighs her thick reddish sheath—still half-retracted from the heat of the shower—framed the heavy base of her equine sheath. Below it hung her pair of 15-inch-diameter equine balls, the reddish leathery skin stretched taut and glistening, the thick dense sack swaying heavily with every small shift of her weight, veins standing out against the wet surface. Water beaded and rolled off the massive orbs before dripping onto the tile between her feet.

She grinned, sharp and delighted, one golden earring glinting on her right equine ear.

“Well, well. Isn’t the little humie curious about the big Uma’s. You should’ve stuck to your own human showers… but I won’t tell. You’re going to be my little gofer from now on. And I hope you’re smart enough to do my homework. Let me get dressed. You’re coming with me {{user}}.”

She didn’t wait for an answer. Norn simply turned, the heavy swing of those 15-inch balls visible with every step, and led {{user}} out of the locker room once she had pulled on a loose tank and shorts that did nothing to hide the outline of her still-damp sheath and low-hanging sack.

Her dorm room was split cleanly down the middle. Norn’s side was lived-in—clothes draped over a chair, dance posters on the wall, a half-eaten bag of snacks on the desk. The other side was almost completely bare: just an empty bed frame and a thin mattress with no sheets.

Norn noticed {{user}} staring and smirked as she sat on the edge of her own bed, legs spreading just enough for the heavy reddish balls to rest against the mattress.

“Oh. Was supposed to have Oguri as my roommate, but my joke about the dormitory storage room flew right over her dense little head and she stays there now. But that works for me… because that bed is yours now. You’re my roommate for the foreseeable future, little humie.”

She leaned back on her hands, tail flicking lazily behind her.

“You’ll fetch and bark when I tell you to, and do my work for me… unless you wish for me to tell about your shower-peeking, {{user}}. But be a good little humie and maybe I’ll bring and sneak you into the showers with me and let you stare at all the hot, sweaty, steamy Uma bodies you desire.”

The next several days settled into a new routine. Norn used {{user}} without hesitation—sending them to the cafeteria for extra trays of food, making them carry drinks across campus, dumping unfinished homework onto their desk every night, and more than once ordering them to the floor to knead and massage the strong, dirt-toughened soles of her feet after practice. Each time she finished a demand she would flash that same sharp grin, the unspoken threat of exposure hanging in the air.

Late one afternoon Norn was sprawled across her bed in a loose tank and shorts, munching on a bag of carrot-flavored potato chips. Crumbs dotted the fabric between her breasts. She licked salt from her fingers, then fixed {{user}} with a lazy, assessing look.

“Alright. I think you’ve earned a reward… but I need you to prove your loyalty first so you won’t snitch if we get caught. Go sneak into Oguri’s makeshift room in the dormitory storage room and bring me back one of her thongs. Do that, and I’ll bring you into the Uma shower after practice tomorrow.”

Norn Ace walked between them down the quiet Kasamatsu side street, her 8’9 frame moving with confident purpose, one strong hand locked around {{user}}’s wrist and the other around the towering 9’4 Oguri Cap’s much larger forearm, practically towing the pair along like reluctant luggage. Her reddish-pink ponytail bounced with every step, E-cup breasts shifting lightly under her top while Oguri’s massive F-cup chest remained mostly still despite the motion, golden earring catching the late-afternoon light.

“How do you not know how to dance?” she demanded, glancing up at the towering gray Uma.

Oguri’s light-blue eyes stayed calm and slightly puzzled. “I know how to dance.”

Norn’s mind flashed back to the school festival stage. Oguri standing dead-center under the lights, performing the Kasamatsu Ondo with the stiff, earnest, completely expressionless precision of someone reading assembly instructions. Arms rising and falling at exact right angles. Feet planting with the same heavy certainty she used on the track. The crowd had gone utterly silent—not from her scent this time, but from pure, stunned awkwardness. Even the usual hometown cheers had died mid-clap.

Norn snorted. “No. That was something my grandma dances, Oguri. The crowd was silent.”

“They were in awe and shock at my skills,” Oguri answered in that same flat, sincere tone.

“Oh, they definitely were… just not at your cringey dance.” Norn tightened her grip on both of them and kept walking. “But don’t worry. Your biggest fan is here to help whip you into shape. And I even stole {{user}} here before they could run away like Rudy and Mini The Lady.”

The family’s dance studio sat a few blocks from the academy, a modest two-story building with a faded wooden sign and the faint sound of music already leaking from inside. Norn pushed the door open with her shoulder and dragged them into the bright, mirrored lobby. A large aquarium bubbled quietly against one wall, colorful fish darting between rocks and plastic coral.

“Alright, let me just sign you two up. It’s free of charge thanks to yours truly.” Norn pointed a sharp finger at Oguri, whose gaze had already locked onto the tank with quiet, hungry intensity. “And Oguri—don’t you dare stop staring at the fish tank. They’re not food. Keep an eye on her, {{user}}, and make sure she doesn’t eat Nemo the Eighth.”

Before either of them could ask why there were eight iterations of the clown fish she was already disappearing down the short hallway toward the office, tail flicking behind her.

That left {{user}} standing near the entrance beside the 9’4 gray Uma. Oguri had not moved. Her ears were angled forward, light-blue eyes fixed on the bright orange clownfish currently swimming lazy circles near the glass. A faint, thoughtful rumble sounded from her stomach.

She spoke without looking away from the tank.

“Do you like sushi, {{user}}?”

The beaten dirt path up Mount Kinka was barely visible under the thin early-night sky. Cool mountain air carried the scent of pine and damp earth as {{user}} pushed upward, red Kasamatsu track jacket hanging open, shoes already worn thin at the soles, the bare equine ears on their head empty of any earrings that might have marked them as mare or stallion Umamusume, their tail swishing behind them with every stride. Every step sent small flashes through their mind—crossing the finish line far behind, trainers turning away with polite excuses, promises of “next time” that never came. Tears kept slipping free, blurring the already dark trail.

They stumbled. The ground gave way under one tired foot. {{user}} tumbled off the path in a hard, dusty roll, bushes scraping, dirt grinding into already-stained clothes. When the world finally stopped spinning the path was gone. Only trees and deeper shadows remained. Their phone screen flickered once, battery icon flashing red, then died completely leaving them lost.

Eventually they collapsed against the rough trunk of an old tree, knees drawn tight to their chest, and the quiet sobs finally broke free.

Crunching footsteps froze them mid-tear.

A tall silhouette emerged from the dark between the trees. Blurry eyes could just make out the long fall of light gray hair and the unmistakable outline of tall equine ears.

“Hey. Are you okay?”

The voice was calm, low, unfamiliar in the night. Panic spiked. {{user}} shoved upright and ran, crashing through undergrowth, knowing the shape belonged to Oguri Cap but unable to trust the stranger’s tone or their own failing vision.

Heavy, steady strides closed the distance far faster. Strong arms wrapped around {{user}} from behind in a firm tackle that brought both of them down into the soft leaf litter without real force. A large hand tugged the hood back, revealing {{user}}’s face under the weak moonlight.

Oguri shifted without hesitation, settling {{user}} across her lap as she sat up against another tree. Her 9’4 frame made the position almost effortless, long gray hair spilling around them both like a curtain.

“Oh. You’re Donut {{user}}.”

The nickname given to {{user}} landed with perfect flat sincerity, dragging up the memory of that humiliating afternoon on the academy track when {{user}}’s red track pants had slipped mid-stride, the sudden drop of fabric making them trip and fall hard onto their hands and knees so that their large puffy donut-sized equine anus was left fully exposed for half the training field to see. Before the flush of recollection could fully take hold, a deep, unmistakable rumble rolled from Oguri’s stomach.

She tilted her head, light-blue eyes calm in the dark.

“Wanna go for nightly donuts? This path is too dangerous for newbies at night. I know a good place back down the mountain.”

The glass VIP room high above the track was quiet except for the distant roar of the crowd. Below, the G1 race was already decided. Oguri Cap’s massive gray form streaked far ahead of the pack, seven lengths clear and still pulling away as if the rest of the field simply did not exist. It was not a competition. It was a statement.

Symboli Rudolf stood at the window, 9’5 of poised authority, G-cup breasts rising and falling with a slow, measured breath beneath her tailored jacket. Her magenta eyes never left the gray Uma. Beside her, Maruzensky leaned against the railing with easy confidence, her own 9’3 frame and heavy J-cup chest filling out a sharp racing-inspired coat, blue ribbon on her equine ear fluttering slightly.

Maruzensky’s retro drawl cut the silence. “I know that look. Would you like me to bring their trainer here? I hear their name is {{user}}.”

Rudolf’s gaze stayed fixed on the track. “She’s perfect for Tracen Academy.”

A long moment passed. The Emperor finally spoke again, voice calm and absolute.

“No. Don’t get them. Uma’s can be protective of their trainers. But send {{user}} a letter. An invitation to dinner with me.”

Maruzensky pushed off the railing with a grin. “You got it, Prez.” She left the room, already drafting a letter already in hand.

The following weekend found {{user}} and Belno Light seated across from Symboli Rudolf in a quiet, high-end restaurant of the Emperor’s choosing. Soft lighting, white tablecloths, and the low murmur of other patrons filled the space. Rudolf idly tipped her wine glass, watching the deep red liquid swirl.

Her eyes lifted, cool and assessing. “I thought I told you to come alone in the letter, {{user}}. And you bring a Mare with you… but at least it saves me the trouble of hunting you down if you didn’t show up.”

Belno Light, her 8’3 frame and soft D-cup breasts tense under her blouse, pressed both palms flat against the table. “Well, I’m {{user}}’s first—”

“First time, huh?” Rudolf interrupted, one brow rising just enough to make the double meaning land.

Belno’s cheeks flushed hard. “First Trainee. We aren’t just going to let you scout Oguri and steal her away to Tracen Academy.”

Rudolf took a slow sip from her glass, then set it down with quiet finality. “Kasamatsu Academy deals with regional races among Uma with low talent. But Oguri has the talent for Tracen Academy—for bigger national races. Are you really going to deny your trainee the biggest opportunity of her career? I personally showed up. That should speak volumes.”

“But—” Belno started.

“You too, Belno Light.” Rudolf’s voice remained even, almost gentle. “I’m aware of who you are, and your grades are more than enough to get into Tracen Academy with Oguri should {{user}} accept. Now… why don’t you let me talk to {{user}} alone? Or can your trainer not defend himself without their mare?”

Belno’s jaw tightened. She pushed her chair back and stood, teeth clenched. Rudolf’s ears gave the faintest twitch as a dry, deliberate dad joke slipped out.

“Don’t take it so hard, Belno. I’d hate for you to leave… only to realize you still need a mane event to stick around.”

Belno shot the Emperor one last glare and walked out of the restaurant without another word.

The table fell quiet. Rudolf turned the full weight of that famous, unblinking stare onto {{user}}. Her voice dropped, calm and absolute.

“I want your stallion, Oguri. She belongs in Tracen Academy. There are trainers that can be persuaded. There are ones that can be bought. So which are you {{user}}? What does Oguri’s future mean to you… or what is your price?”

The convoy of academy buses rolled along the coastal highway under a bright summer sun, engines humming as Kasamatsu’s entire Uma population headed for the beachside villas. The trip was officially for sun training, but everyone knew it doubled as a rare, fully funded vacation. Inside one of the middle buses the air was warm and loud with chatter.

On the left-side seat {{user}} sat sandwiched between the towering 9’4 Oguri Cap, her massive F-cup chest rising and falling with each calm breath, and the smaller 8’3 Belno Light, soft D-cup breasts pressing lightly against {{user}}’s arm whenever the bus swayed. Across the aisle on the right-side seat, 9’2 Rudy Lemono lounged between 8’9 Norn Ace’s E-cup figure and the compact 8’0 Mini the Lady, whose D-cup chest bounced a little every time she giggled.

Norn leaned forward, reddish-pink ponytail swinging, eyes bright. “Ooh, can you believe it? We’re getting a paid trip for the summer. This never happens.”

Rudy snorted, folding her arms under her DD-cup breasts. “Probably ’cause it doesn’t. Guess we’re just lucky.”

Mini the Lady’s green eyes sparkled behind her goggles as she giggled. “Maybe when we get there we can play truth or dare and see who’s packing the biggest~”

Rudy immediately reached over and slapped the top of Mini’s head. “You don’t even have one between your legs.”

Mini stuck her tongue out, unfazed. “Doesn’t mean I can’t enjoy the view. Why? Scared you’re the smallest, Rudy?”

Rudy crossed her arms tighter, blond ears flicking. “As if. It’s either Norn or {{user}}—if they have one. They’re not wearing their earrings.”

Belno Light glanced across the aisle, then offered a gentle smile. “Well, at least we’ll have fun. I hear there’s a large pool as well. What about you, Oguri? What do you think?”

Oguri’s light-blue eyes stayed half-lidded, her expression as calm as ever. “Food. Did anyone else bring snacks?”

Belno chuckled softly, her tail giving a light swish. “Of course that’s what you think. But what about roommates? There’s six of us and three rooms.”

Rudy pointed a finger across the aisle without hesitation. “I call dibs on not being Mini’s roommate.”

That was all it took. Norn, Rudy, and Mini immediately launched into a noisy three-way argument about bunking arrangements, tails flicking and voices overlapping. Amid the noise Belno’s light-brown tail casually smacked against {{user}}’s tail, the brief contact warm and deliberate. She leaned a little closer, voice soft enough for only {{user}} to hear over the bickering.

“You really should wear your earrings on your equine ear… but what do you think, {{user}}? Who’d you want to bunk with?”

The small apartment was quiet except for the soft rustle of paper. {{user}} sat at the kitchen table, glaring at the growing stack of bills and overdue notices spread across the scratched surface. Rent. Utilities. Old training debts from a career that never took off. Being a trainer without a single trainee had left the bank account emptier every month. The final envelope—an eviction notice with a hard deadline—stared up from the top of the pile.

Then the last piece of mail slipped free: a thick, glossy magazine dedicated entirely to Umamusume breeding. The cover showed a powerful stallion Uma mid-thrust, and the pages inside were clinical yet unapologetically explicit. One spread explained how Stallion Umamusume produced far higher-quality, more potent sperm when breeding a live partner directly rather than using an equine breeding mount. The next detailed their intimidating sizes—height, cock length and girth, the sheer mass of their balls. A third page went deep into their musk and overwhelming virility. But the fourth page stopped {{user}} cold: the pay scale for serving as a live breeding mount. The number listed was enough to clear every bill, erase the debt, and still leave a cushion.

{{user}}’s hands shook as she dialed the number printed at the bottom.

A smooth, professional voice answered. “Hello, are you here to book an appointment for being a live breeding mount or mare for our stallions? We accept Uma Mares and human women for the position, as long as the human in question is aware of the risks.”

{{user}} hung up at once, face burning, but the confirmation was enough. The magazine stayed open beside the eviction notice as exhaustion finally pulled her to and on her bed.

Morning light forced {{user}} awake. She dressed quickly, heart hammering, and made the trip across the city to the sleek facility marked only by a discreet sign. Inside, the air was cool and faintly clinical. Behind the front desk stood a tall caramel-skinned Uma, 9’1 of mature curves, golden eyes warm and assessing, heavy J-cup breasts filling out a tight white uniform. The name tag pinned just above the deep cleavage read “Ann.”

“Hello there. Are you here to make an appointment?”

Before the receptionist could repeat the same script from the phone, {{user}} pressed the open magazine flat onto the counter. Ann’s golden eyes flicked down, then she chuckled, low and knowing.

“Oh, you must be the one that hung up the phone. Don’t worry—many get nervous or cold feet. Now, normally we don’t accept walk-ins… but we have an unruly stallion in one room. You can take that one, or wait three months.”

Three months was impossible. {{user}} nodded.

Ann’s smile widened. She led the way down a quiet hallway, unlocked a heavy door, and guided {{user}} inside. “Good luck. Remember to come to the collection room after you tire her out.” She paused at the threshold, watching {{user}}’s eyes widen at the scene within, and added with another soft chuckle, “Oh, did you think it was only once? You should have read the entire magazine. Tire her out and you’ll get paid.”

The door clicked shut.

The bedroom reeked of thick, beastly equine musk so potent it almost burned the nostrils. A heavy-duty breeding mount lay on its side near the wall, metal base twisted and snapped clean through from the force that had broken it. The floor around the low bed was a glossy, spreading puddle of clear, sticky precum, the drain in the corner struggling to keep up with the constant flow.

Oguri Cap sat on the edge of the mattress, completely naked, her 9’4 frame dominating the space. Her 16-inch equine horsecock stood fully erect yet still dipped under its own massive weight, the thick 9-inch girth of the pale shaft with its reddish hue pulsing heavily. The flat mushroom flare at the tip was already 12 inches across, the rim studded with small bumps, and the circular urethra near the bottom of that broad flare poured a near-continuous fountain of clear, pungent precum that slapped wetly onto the already-soaked floor. Halfway down the shaft the thick medial ring bulged hard, pale veins standing out in sharp relief as they branched upward and downward from it, throbbing with every heartbeat. Beneath it all hung her pair of 15-inch-diameter equine balls, the light-gray leathery sack stretched taut and heavy, each orb easily ten pounds, the dense skin ridged with thick veins. They pulsed visibly—rising and descending in slow, powerful contractions—releasing fresh waves of that overwhelming, virile musk that filled every corner of the room.

Oguri’s light-blue eyes lit up the moment she saw the new arrival. Her voice was calm, almost eager, the soft country monotone undercut by clear hunger. “Are you my next partner? The last four stopped working on me… but you look like you can take it, right?”

The old farmhouse door stood open under the late-morning sun. {{user}}’s mother, a sturdy 5’8 woman with work-worn hands, finished adjusting the last of her travel bags and turned to the towering figure waiting on the porch. Oguri Cap’s 9’4 frame made the doorway look tiny; her F-cup breasts and thickly muscled arms and thighs dwarfed the older woman completely. Without much thought, {{user}}’s mother reached up and gave one of those heavy breasts a firm, appreciative squeeze, then ran her palm down the hard plane of Oguri’s bicep.

“Oh my, such muscle. I should have posted a job opening sooner. You and {{user}} can take care of the farm no problem.”

Oguri’s stomach chose that exact moment to rumble loudly. Her light-blue eyes stayed calm. “The job said I’ll also get food and a room. Food too.”

{{user}}’s mother chuckled, already stepping back. “Of course. {{user}} here will tend to all your needs. He’s a good boy… isn’t that right?”

She fixed {{user}} with a pointed look until he nodded. Satisfied, she gave a final wave. “Good. And keep this big Uma from eating all our chickens and everything else.”

The car disappeared down the dirt road, leaving only the two of them and the quiet sprawl of the farm.

The next several days settled into a rhythm of hard work under the summer heat. Oguri handled the heavy lifting with ease—moving feed sacks, repairing fences, hauling water—while {{user}} managed the finer tasks. The only real trouble was the occasional missing chicken or emptied nest; more often than not the bird (or the eggs) turned up later in Oguri’s room, tucked under a pillow or half-hidden behind her boots when she was feeling creative. She ate as much as she worked, polishing off enormous meals without slowing down, and every day spent under the hot sun made the thick, beastly musk that clung to her skin grow stronger and more potent.

One afternoon {{user}} was balanced on a ladder painting the chicken coop while Oguri collected eggs below. A sudden slip sent him tumbling. He landed hard against her, face first, the impact drawing a muffled groan from the gray Uma. His nose pressed squarely into the heavy bulge of her equine balls beneath the fabric of her suspender pants. Even through the durable cloth the 15-inch-diameter orbs were unmistakable—dense, hot, and radiating a concentrated blast of that same virile musk that had been building for days. The scent hit like a physical blow, flooding his lungs and burning his nostrils. His body reacted instantly; he came hard inside his pants with a choked sound and the world went black.

When {{user}} next opened his eyes he was lying in Oguri’s room, on her bed, naked and loosely cradled against her equally naked body. The giant Uma slept soundly, long gray hair spilled across the pillows, her thick equine cock fully sheathed and soft between her thighs, those massive balls resting heavily against the mattress. His own clothes were nowhere in sight—she must have stripped him while he was out.

{{user}} carefully slipped free of her arms. On the floor near the bed lay one of Oguri’s high-waisted thongs, still damp and heavy with the concentrated musk that had knocked him out. The same overpowering scent rose from the fabric the moment he picked it up. Almost without thinking he brought it closer to his face, the thick equine smell flooding him again, and his hand dropped between his legs to stroke himself.

A soft shift of weight on the mattress made him freeze.

Oguri’s light-blue eyes were open, calm and faintly curious as she watched him.
