The sun baked the wild meadow, the heavy scent of grass and flowers filling the air. Out in the middle of it, a massive anthro horse had cornered a full-grown man, a strong adult who had wandered too far from the path.
Without warning, the stallion seized him by the back of the neck, his thick hand clamping down hard. The man struggled, gritting his teeth, but there was no escape. The beast was stronger, bigger, overwhelming.
Their mouths crashed together, the stallion's thick tongue forcing its way deep into the man's mouth, spreading warm saliva mixed with something else, something potent. A heavy taste of sweat, earth, raw male musk and the sharp metallic tang of magic.
The man groaned low in his chest as his body started betraying him. His cock throbbed violently in his pants, growing hotter, thicker. His skin darkened, stretched tight, reshaping itself. In seconds, his manhood morphed into a heavy, black equine shaft, drooling down his thigh.
The stallion deepened the kiss, pushing the transformation deeper. The man's jaw began to crack and push forward, his nose flattening into a wide, black snout. Coarse fur sprouted across his chest, arms, and legs, sweeping over his muscles.
Bones shifted under his skin, reshaping with brutal snaps. His hands broadened into thick, strong hooves, his legs twisting into the powerful, digitigrade shape of a horse's hind limbs.
The stallion finally pulled back, saliva dripping from both of them. His new prize knelt in the grass, panting heavily. His wide, heavy equine balls hung low between muscular thighs, and his transformed cock twitched, leaking. His mind was already starting to slip, instincts surging up from the new body.
The dominant stallion stepped behind him, grabbing his hips. There was no gentleness. He lined up his massive, pulsing cock and shoved inside with one brutal thrust, stretching the new stallion's fresh hole wide around his girth.
The meadow filled with the wet slap of bodies and low, rumbling grunts. The transformation was complete. Now, it was time to claim him fully.
The new stallion gasped, his tongue hanging from his thick lips, drool spilling down his chest as the alpha hammered into him. Each thrust forced a guttural moan from his throat. He could feel the powerful shaft battering his guts, claiming him over and over. His own cock, heavy and uncontrollable, swung beneath him, drooling constantly into the grass.
The alpha snarled above him, grabbing his hips tighter, slamming forward with brutal force. Every thrust shoved him forward into the dirt.
Then, with a savage growl, the alpha drove deep and came.
Hot, thick cum exploded inside him in massive gushes. It filled him instantly, the pressure inside growing unbearable. Another pulse hit him, then another. The seed had nowhere to go but deeper, stretching him.
He moaned brokenly, feeling his stomach start to swell outward. First it was tightness, then a visible rounding. His heavy equine belly bulged under the sheer volume of seed pouring into him, his insides flooded, hot and pulsing.
The alpha kept thrusting slowly as he emptied himself, hips grinding into the overfilled stallion's rear, forcing even more inside. The new stallion's eyes rolled back, lost in the overwhelming sensation. His skin stretched taut over the growing dome of his belly, sweat and cum dripping down his body.
When the alpha finally pulled out, a thick river of seed gushed from the gaping hole, but his belly remained heavy, swollen, sloshing slightly with every movement.
He was full.
Bred.
Transformed and marked forever as the property of his dominant stallion.
