Who could ever say no to two big, burly bull boys showing off and getting a little too into it? Huge thanks to  buffbuck for letting me write this story, and of course to our two very willing (and very beefy) volunteers, Whey and Gren. You boys really brought the horns, the heat, and the charm! Find those two on Bluesky on these clickies! !!WHEY!! AND !!GREN!!

Whey and Gren stood in front of the mirror, holding their new bells and eyeing them with some hesitation. The bells, shiny and bright, had caught their attention earlier that day, and now they were about to try them on.

"Check it out, I herd these bells are totally in right now," Whey said, a grin spreading across his face. He was already slipping the cow bell over his head, the jingling noise filling the air.

Gren eyed his own bell hesitantly. "They are? I- don’t know… I think I might be allergic to them. Maybe the metal or something?"

Whey chuckled. "Naw, that's udderly ridiculous, it's exactly how they're supposed to work."

"Work?" Gren raised an eyebrow as the bell gave another soft clang.

"Yep! Not to mention our noses. Oouuuh- and here comes the hair!" Whey beamed, already feeling his own hair shift slightly, though it was still too early to tell exactly what was happening.

"Now you're catching on!" Whey said, watching as Gren's fingers twitched nervously. He let out a laugh and tapped the bell, which made another soft clang.

"Hold on, are these COW bells?" Gren asked, his voice rising in confusion. He took a step back, suddenly looking more worried.

Whey gave a hearty laugh, the bell at his neck clanging again. "Duh. They're all the rage! Brings out the bull in everyone."

Gren blinked. "The what now?" He scratched the back of his neck, a nervous habit, but this time, his fingers paused. The skin there felt strange. Thicker. Warmer. A little… fuzzy?

His eyes narrowed as he rubbed at it again, fingertips brushing over a soft patch of white fur that hadn’t been there earlier. He swallowed, suddenly aware that the muscles around his shoulders were beginning to feel tighter, subtly swollen beneath his shirt. He flexed unconsciously, brows furrowing.

"Uhh... Whey?" he muttered, voice uncertain.

Whey leaned in, bells jingling merrily with every movement. "Oh, relax. You're just feeling the fashion sink in." He winked, tossing his head so his own bell gave a satisfied clang. "That means it’s working."

Clang.

Gren’s bell chimed again as he shifted again, the collar of the bell feeling tighter around his thickening neck. Each time the bell rang, something changed, just a little. A tug, a slow stretch, a warm pulse of pressure somewhere new on his body. He didn’t want to believe it, but…

Clang.

Another change rolled through him. His nose twitched, then started to broaden at the bridge. His nostrils flared, flattening slightly, growing more pronounced. He touched his face and froze. The tip of his nose had become spongy, almost leathery, like a…?

Clang.

Whey let out a pleased sigh, feeling his own nose push forward subtly, reshaping into something rounded and dark. He laughed and turned toward Gren, and that movement triggered another metallic clang from his bell. Their changes echoed off one another in time.

Clang.

Their noses stretched further, soft and wide, the skin darkening. A soft sniff escaped Gren’s mouth as his lips pressed outward slightly, the start of a snout rounding his face. His eyes widened.

"My nose is…" he stammered, then stopped as he felt another change somewhere else. The sides of his head tingled, and he yelped softly as both his ears drooped, lengthened, and flopped down into soft, furry cow ears.

Whey was already giggling. His ears had done the same, hanging low beside his head in gentle, fuzzy arcs. He gave a proud little shake to jingle his bell again, clang, and his grin only widened as his snout grew broader.

Gren clutched at his bell’s strap. "Dude, I am definitely allergic to these!"

Whey stepped in close, nudging his changing friend with a broadening snout. "Pssh. That’s not allergy, bro. That’s just bringing out the big bull in you!"

Clang.

Whey’s bell rang again as he tossed his head with a flick of excitement, and this time, his ginger hair tumbled forward, messily draping over one eye. He blinked through it, snorting as his snout gave another stretch outward, sealing the look.

His face was now fully bovine, soft muzzle, broad dark nose, warm brown fur creeping up his cheeks, and two thick ears flopping low at the sides.

Clang.

Gren's bell echoed in reply, and he staggered a little, feeling the shift as his snout pushed the last inch forward with a slow, fleshy glrk. His nose was broad and strong now, nostrils twitching. He touched it, running his thickening fingers over the velvet soft surface in disbelief.

Then he caught sight of himself in the mirror.

"...Holy..." Gren trailed off.

His body was enormous. Bulging with thick muscle, his chest looked like a pair of drums wrapped in short, smooth fur. A heavy six pack rippled down his torso, clearly defined even through the growing patches of black and white fur spreading across him.

Pecs twitched with every breath. His arms were massive, veined, bulging with biceps so swollen they looked ready to tear through his shirt, would he have been wearing one from the start. His shoulders rolled like cannonballs under skin that was now dappled with spots, black and pale, with thick veins trailing down to strong forearms.

His thighs and calves were equally monstrous, straining against his jeans, and his neck had become a thick trunk of muscle, supporting that now undeniably bovine head.

The white fur on his back shone faintly in the mirror, tapering into thick streaks of black. His ears twitched. His tail, a thick tufted thing, swished behind him lazily.

“Dude...” Gren breathed. “I look like a freakin’ tank.”

Clang.

Whey gave a snort of approval, stepping into frame beside him. He was smaller than Gren, a little less broad, but no less cut. His orange and brown fur had spread in soft waves across his chest and shoulders, curling around a lean, chiseled core.

His six pack was tighter, more compact, almost model like, and his biceps were cut with neat definition. Even his pecs had a bounce to them now, much like Gren’s, and his thighs were thick and toned with that same strong bovine bulk, if slightly slimmer than Gren’s hulking legs.

Hair still hung over one eye, giving him a cocky tilt to his expression. His ears twitched with every clang of the bell around his thickened neck, and his broad snout curled in a little smirk.

“You ain’t lookin’ so allergic now, big guy,” Whey teased, giving Gren a playful nudge with his shoulder. “Told you. Bull looks good on you.”

Clang clang.

Clang.

The sound rang out as Gren took a step back, still staring at himself in the mirror. He felt himself shifting. His toes clenched instinctively… and then locked.

He gasped, lurching forward as the bones reshaped. His feet swelled, toenails blackening and fusing as they pushed outward, wide and heavy. With a final shudder, both feet solidified into thick, heavy hooves that clacked loudly against the floor.

Clack.

Clang.

Whey grunted as the same transformation took him. He reached to steady himself against the wall, panting as his ankles lengthened and shifted, the muscles in his calves bulging even more. His hooves hit the floor with a deep, solid thud, and a grin crossed his broadening muzzle. “That’s more like it…”

Gren staggered upright, adjusting to his new stance, which was digitigrade now, standing tall and solid. His entire body pulsed one last time with a thick wave of heat, and his muscles seemed to inflate. His traps pushed up higher against his neck, his arms bulged outward, lats flaring wide like the frame of a bull primed for show.

His abs flexed and his thighs finished their transformation, becoming brawny trunks that would crush anything between them. Veins pulsed beneath the fur, especially around his forearms and chest.

He took a breath and snorted through his broad cow nose, just in time to feel a sharp tug at his ear.

Shkt.

Something clicked into place, metal and plastic. Gren winced, then reached up… and felt it.

A yellow tag. His ear twitched beneath it, but the plastic didn’t move. Burned into it was a clean, bold number: 48.

“What the hell?”

Clang.

Whey was giggling again, looking down at himself with open pride.

Shnk.

He flinched slightly as a golden hoop slipped into his wide, black nostrils.

Then another tug, two small, gold rings pushed through the soft flesh of each ear.

Whey blinked, his muzzle curling upward. “Oooohh yeah… That’s the stuff.”

Gren stared at him, eyes wide.

“Yooou… gooot rings?” he said, his voice deeper, rougher… and slightly moolodic.

Whey tilted his head, his bell clanging softly.

“Fashion, bro. Goootta ooooown it.”

Clang.

Clang… clang… clang.

Something tensed behind both their temples. Whey blinked, then grunted as two thick nubs pushed up from beneath his shaggy hair. His head tilted slightly as they lengthened, slow, curved, and ridged.

His horns thickened with each passing second, curling forward toward his ears with a strong, blunt curve. He gave his head a lazy toss, and they felt good, like they belonged.

Gren’s change was slower but stronger. His horns pushed up straight through his dark hair with a solid crrk, twin growths of power spiraling upward. They curled forward and up more dramatically than Whey’s, wider at the base, rough with strength. He reached up, hesitantly brushing a hand along one.

Whey grinned at him, “Told yaaa. Brings oooout the bull in yooou.”

Gren let out a slow exhale, his massive chest rising with the motion. He didn’t even try to deny it anymore. The fur, the muscles, the nose ring and tag, the hooves, the horns, all of it clanged softly in rhythm as they stood face to face. Huge, heavy, strong.

“Heh… brings out the bull in you, Whey,” he rumbled, reaching out to tap the gold ring hanging from Whey’s wide, soft nose. “And I’ll put the bull in you later…”

Whey leaned in closer, muzzle practically brushing against Gren’s. The ring through his nose swayed slightly, catching the light. His thick orange hair spilled forward as he tilted his head playfully, heavy bells swinging between them.

“Well let me moooove on closer and get a better look~” Gren said, rich with that unmistakable bovine timbre. It rumbled in his broad chest, not quite a moo… but close.

Gren felt his own bell give a gentle clang as he turned to face him, eyes wide, ears flicking. His brow furrowed, but he didn’t step back. The warmth from Whey’s breath, the sway of his tufted tail, the soft echo of the bells… it pulled him in.

“Y-Yeeaaah? That sounds good to me~”

The air that sat between both of them was thick. Their massive chests rose and fell in sync, bells continuing to clang with each breath.

Clang… clang…

Gren let out a snort through his wide nostrils, as he looked Whey up and down with obvious hunger. That orange brown fur… the gleam of that cute ring, the way his bell swayed… gorgeous.

Another snort. Both of them this time. Deep and hot. It sent a shiver through them.

“Daaamn- yoouuuu loooook soouu- good…” Gren muttered.

“Sooo- douu yooouuu…” Whey replied, voice a little breathy.

Their snouts pressed together. Just gently at first, a brush, then firmer… and heavier. A deep kiss between two big bulls, noses locking, bells clanging once more.
