“Rut me…”

Hitch felt his body move, his muscles activating and pulling him along, as if he were watching himself from afar…the magic had taken over now entirely, putting him into autopilot. Here was a needy mare. His mare.

And he wasn’t going to let her down.

With sudden, inexplicable body coordination, Hitch’s hips flexed as he took his powerful, flared erection in hoof… his new muscles and stockier frame were perfectly suited to handle his massive erection… as if he’d been this way his whole life.

With little more than a feral grunt and a throaty growl, he nestled his massive black bulb into Sunny’s wanting marehood.

And thrusted.

“Oh, BUCK!” Sunny’s scream vibrated through her whole body -- Hitch could feel it in his cock, as Sunny’s grasping walls hummed around him.

She wasn’t like Izzy -- it wasn’t that she was loose… if anything the muscular force behind the well-toned earth mare’s body allowed each convulsive squeeze of her sex to surpass even the tightest vice-gripping moments of Hitch’s romp with Izzy… but she was built to take a stallion like him.

Inch after inch of potent, powerful flesh slipped deep into the young mare’s body, opening her in a way nothing ever had before. Nasty squelching sounds filled the room as Sunny’s copious lubrication was displaced by the sheer volume of cock entering her body.

It was hard pushing into her, like pushing a golf ball through a rubber hose… but the sheer force of his muscles, the power in his hips and lower body was driving all of him into her.

“H-hitch!” Sunny’s tail thrashed against his chest, her tight ponut quivered as he took her like she was some broodmare on the ancient plains of primordial Equestria.

There was only a brief interruption as his medial ring abutted her tightness… the impressive donut of his stallionhood was a clear separation between the relatively slender part of his upper shaft and the astonishingly thick growth of the trunk of his base.

But even that slipped into Sunny with a light pop… the mare’s pussy-lips stretching wider and wider, to an almost impossible degree as they opened to accept the rapidly expanding width of his girthy lower penis…

“OOF!” Sunny gasped, the breath driven from her. Hitch has just slammed into her cervical opening, pushing the mare down into the bedtop, his stallionhood spearing through her body with a noticeable bulge above Sunny’s belly button.

“Oh, Goddesses! YES!”

Hitch hadn’t heard Sunny profane the absolute before.

The orange-furred mare began to press back in what feeble way she could, tilting her hips to allow more of the raw muscular force to lever its way into her.

Hitch could feel his sizeable head grinding, parting, the holy sanctuary that was his best friend’s womb… the diminutive cervical opening dilating and straining.

He was slipping into her!

Hitch would scarcely have believed it was possible, even though he knew that something the width of a foal’s head must pass through that narrow channel. He wasn’t sure if his current girth matched that of a newborn’s skull… or if it surpassed it.

“HITCH! HITCH!”

*pop!*

With another throaty growl, and an audible pop, Hitch sank the final 3-inches of himself into Sunny, his huge flare fully invading her uterus… slamming up against the far wall as he barely hilted his mare.

“Graaah!” Hitch snarled, a burning ferocity exploding in his breast, a snort of triumph escaping his flared nostrils. He stiffened his forearms, pulling up and away from his well-bedded mare, momentarily lifting her with the sheer strength and rigidity of his phallus… before slamming back down into her again, driving all the wind from her lungs.

*plap*

The wet slap of his heavy ballsack smacking against her soaked nethers filled the room and soon became a metronomic signal to anypony within earshot that a sizable stud was ferociously breeding his mare, at a pace that would shame a jackrabbit.

*plap* *plap* *plap* *plap* *plap* *plap*

“Graaaah!”

There was no mercy, no tenderness, or kindness in his sheer, raw, fucking. This was a burning desire, a need, something inculcated by the potent, incessant swirling earth-pony magic that insisted he breed… without delay.

“Hitch! Hitch! Hitch! Hiiiiiiiiiitch!!!!” Sunny’s squeals of his name only kept pace with his thrusts for a few measures worth of his carnal song, before her voice cracked and broke… as a wave of her orgasmic pleasure stole any control of the pitch and timbre of her voice.

But he just kept fucking her. Harder and harder.

Hitch wasn’t some animal… the odd tryst he initiated with one of Maretime Bay’s mares were always sensual, slow, often comedic sessions. He was a sucker for a good cuddle…

But that wasn’t Hitch now. Now his teeth were grit with a mixture of rage and focus, his bulging muscles thrummed with purpose, and his heart thumped in his chest to provide his body with the hot-red blood it needed to breed his broodmare.

Harder. Harder! HARDER!

His mind drove him on, the madness of the sounds a mere chorus to the primal, instinctive drive to flood his best friend with fertile, foal-bearing seed.

“AAHahnngnhffnnn….” Sunny’s confused, slurred speech betrayed her complete submission… finally her conscious mind had given out, melting completely in surrender to the sheer pleasure and drive of the much larger stallion taking her in a ferocious rut.

Hitch felt his mare’s body relax beneath him, her muscles unwinding, succumbing in full to the superior exertion of the stallion fucking the Tartarus out of her. It was the final signal whatever primeval instinct that had taken control of Hitch’s body was waiting for -- the confirmation that now was the time to complete this symphony of lust.

“Sunn-nee-heee-heee!!!”

Hitch’s throaty cry broke into a nickering whinny, unlike any sound he had ever made before, as he felt his cock-end re-flare even wider. Its knobby, knurled edges bit into the yielding flesh of Sunny’s womb as it embedded itself in preparation for the storm that was boiling up his pulsing shaft.

As the first eruption exploded from his milkshake-straw-sized urethra, flooding his best friend’s belly with steaming, frothing-white cum, Hitch slumped forward and took a hard bite of Sunny’s nape.

“AAHhahhhhnnn!” Sunny moaned, heart-shaped eyes roiling in their sockets as she quivered under the sharpness of the bite… and the impossibly perfect satisfaction of being filled with Hitch’s magically potent virility.

“GRNNF! GRNNF!” Hitch’s unintelligible grunts were lost in Sunny’s sweaty neck-fur as he humped out his ‘little-death’-strokes. Each thrust drove more, more, MORE ejaculate into Sunny’s ripe body, his big black balls humming-hot with magical earth-pony energy as they churned and delivered impossible quantities of reproductive fluid.

Out and out Sunny’s belly grew, just like Izzy’s had… except Hitch’s cock was too deep to pop out this time… his flare forming a perfect seal like a wine cork to Sunny’s uterus… leaving only the option for her to expand to accommodate his ridiculously-sized wave of life.

*pop*

Her belly button flipped from inny to outie, as her belly swole beyond the size of a mare late in term with foal… and yet Hitch kept pumping, fucking into her. Delivering more, more!

MORE!

“Haaa….. Haaa….. Haaa….”

Hitch’s breath returned to him slowly, his teeth releasing their grasp as some small portion of blood re-reached his more sapient neural pathways, bringing him out of the fog of his passion to feel the last dregs of potent cum slip from his tip into his best friend’s body.

W-what had he done!?

“S-sunny?” Hitch looked down in horror at his friend, giving her a little shake on her left shoulder, petrified at what he had done.

“Mmmmff… yessssh?” The lilting, drunk-happy purr from the semi-conscious earth-mare gave Hitch a momentary glimpse of relief -- she was OK… perhaps riding a bit of an oxytocin high.

“Phew…” Hitch felt himself relaxing, uncoiling… and finally he felt his painful stiffness relent; the iron rigidity in his phallus lessening to something more like an inflated balloon… his rigid flare shrinking just enough to dislodge itself from the perch it had established in Sunny’s nubile flesh.

*Schhloooorp*

The rather disgusting sucking sound of Hitch’s stallionhood pulling out of Sunny’s exhausted vaginal canal filled the room, as he delicately and awkwardly maneuvered his hips to pull the long, limpening noodle of flesh from its comfortably warm burrow.

*SCHL~POP!*

And an audible pop followed, as the very last inch of cock finally slid free from the vacuuming suction of mare flesh, letting a torrent of still-boiling magical seed bubble free from its pressurized velvet container.

It was spilling everywhere.

“Gah…!” Hitch pulled back, dragging his still-long limp snake with him as he made his way to his hooves, and was offered a chance to survey the absolute carnal destruction he had wrought on his two close friends.

Ba-BUMP!

A thrumming pulse hammered from deep inside his loins again, racing up his spine in electric shivers and causing a new rushing release of energy in his limbic brain.

His nostrils flared wide.

He smelled something.

A mare.

Sunny is lucky she had some Earth-Pony-Magic herself to handle big ol' Hitch.
