“Cl-cl-cloudy!” Anon groaned, worried that he was about to experience some sort of horrifying penile fracture.

“Hnnf… s-stop…” Cloudy grunted over her shoulder, straining with the exertion of using all her body to try to impale herself on this man, “...s-stop with the… huf… h-hover hands…! Grab my rump and RUT me… b-buck!”

Her voice commanded obedience - Anon quickly grabbed two handfuls of her buttocks, taking hold so eagerly that it might be more accurate to say that he clapped onto her flanks.

*SLAP*

“Hmmmmnnnf!” Cloudy squeaked, her nose scrunching up and her cheeks pouting out cutely at the unexpected ass-slap. Anon was already pulling with his arms - he was fully committed now: either he would penetrate Cloudy… or his dick would snap in two like a twig.

“Mmmmmmmmgghhh!” Cloudy’s growl rumbled.

“Sh-sh-shiiiiiiiip!” Anon grunted back.

Then it happened.

Cloudy’s strained inner pink lips - drawn out to nearly their breaking point - like a pink latex glover stretched over a melon, slid over the edge of Anon’s cockhead-ridge. In less than an instant, he penetrated deeply into the mare’s tight, twisting love tunnel, burying more than half of his massive, thick log into her cunt.

Hot.

Boiling hot.

The volcanic interior of cloudy was a myriad of sensations, but the overwhelming one was just how steaming her insides were - this little pony definitely ran hot. and strong. her muscles were so powerful - so intense that it made sense to him now why her pussy had been so hard to enter: her vise-like muscles made her as tight as any young, blushing bride.

“F-f-fuck!” Cloudy groaned aloud, an animalistic curse coming from her gut, “...that’s so b-BIG… I haven’t been stretched like that since I birthed Marble!” Her left forehoof thumped the top of the bedspread in reaction to the sensation, as she struggled to cope with the insertion of such a massive object into her body.

It was cute - Anon would have smirked to himself at the domineering mare struggling and failing to handle his big, fat, human dick… if he were not struggling himself with the overwhelming feelings of her massaging, tight cunt-y confines clasping and grasping all around him.

So the two of them just hung there for a few moments, grunt and shifting ever so slightly. Cloudy staring down at the bedspread, clenching the sheets in blissful agony… as Anon stared down at the incredible sight of his thick sausage disappearing into the set of tight, drooling pink lips and dug his fingers into the flesh of Cloudy’s butt as he tried to resist the more potent squeezes of her pelvic floor.

Sweat dripped from Anon’s brow, his breathing slowing synching up with Cloudy’s, as he noticed the nuances of this beautiful mare’s every reaction to his cock - from the myriad clenches and milking jerks of her inner tunnel to little twitches of the muscles along her spine. Slowly, he felt the tension of the mare’s tail release, at first sagging away from his hipline… before slowly stiffening up in front of him, rising higher and higher with each breath, until it was fully hiked up in a flagged position.

Of course, she would recover first.

“Mmm… th-that… that was invigorating.” Cloudy chuckled, blowing a hot gust of steam from her snout, “...really, just as impressive as I’d heard from Twilight Velvet. I had never imagined I’d have the opportunity to…”

Anon suddenly felt Cloudy’s vagina ripple and swirl, her contractions no longer spastic and uncoordinated - clearly back under her control. It was all he could do to bite his lip at the force of the incredibly tight clench of her marecunt around his shaft as if someone had snapped a too-tight elastic band around his cock… one that Cloudy could move up and down his length at will.

“...try…” Another clench.

“...you…” And another.

“...out.” With her last word, Cloudy’s whole tight tunnel cinched down on him as one tube, twisting and binding with anaconda-like intensity.

“H-holy… f-f-f-fiddlesticks…” Anon groaned, fingers clenching into Cloudy’s rear.

“Mmm… yes… that’s right, isn’t it?” Cloudy wiggled her butt, tantalizingly sending ripples through to Anon’s cock, “I seem to recall that you spanked my bottom without my permission, Anon.” Cloudy’s voice scolded.

Anon gulped, his eye’s focusing in on Cloudy’s. That same fire was there… but underneath it was sheen of playful exuberance - this cat knew she’d captured the mouse in her paws… and it was time to play.

“I think some reciprocity is in order… don’t you?” Cloudy grinned.

Anon felt his mate’s body began to pull away from him, ever so slowly. The sucking force of her tight cunt pulled him with her at first, despite the fact that she’d released her grip. It still took Anon needing to almost brace himself against her rock-hard ass to carefully pry his dick out of her tight confines.

Inch by inch, slowly… he withdrew from her. He watched her bright pink inner lips get drawn out from her depths, nasty obscene squelching sounds accompanying the vacuum-seal of pussy against cock breaking as he neared fully exiting her. He could see the fat bulge of his cockhead as it neared the slick entrance of her cunt - the outline of his glans clearly pressing outward against the thin pink flesh.

“I was going to be gentle, since this was your first time doing your husbandly duty with me.” Cloudy’s grin grew wider, revealing the sharp-toothed fang of her canines before she growled sultrily, “...but since you’ve shown that you’re OK with things being a bit rough… I think I’ll go all out.”

Cloudy’s tail once again wrapped around Anon’s belt-line, bracing the human and locking him firmly in place.

“W-wait, C-cloudy!” Anon stammered, barely able to find the words. He wasn’t used to being on his heels like this.

“No, I don’t think I will…” Cloudy’s ass began to move backward, reversing its withdrawal… beginning to jam Anon’s fat human cock back into her volcanic depths, inch by inch.

“Mmmmfff!” Anon grunted, carefully resisting the urge to slap Cloudy’s bottom again. As he sunk deeper into the twisting depths of Cloudy’s pony pussy, he once again felt his passage deeper blocked by an impossible tightness… heretofore unplumbed depths stretching to accept a masculine invader for the first time. It wasn’t easy going - only by the sheer force of Cloudy’s muscular body was he being stuffed into her to such a degree. His cockhead was constricted, to an almost painful amount.

But he still went deeper into her than his first penetration - sinking an extra inch into her heat, leaving only three inches in the cold… if you could call it that. The winking kiss of Cloudy’s clitoris as she gobbled up his girth, and the spattering sputter of her marejuices coated Anon’s base and balls with a warm and pungent slickness.

“I’m just getting started.”

Cloudy reversed direction once again, speeding up ever so slightly. Drawing Anon out of her with the leverage of her body and tail. Anon felt sparkles popping behind his eyes, electricity racing down to his toes… the sensation of her hidden folds running over his shaft’s every crevice and vein simply divine.

And then she plowed backward again. Faster, and with more violence. Spearing herself onto his cock with the full force of her strength, their rapid union sending torrential splashes of unspeakable liquids slopping to the floor.

Only two inches outside, on this stroke.

Anon’s eyes barely had a chance to register the sight of his thickening base stretching the little mare’s entrance to a ludicrous level, before she began to extract him again, her pace quickening with each passing moment as she found a smooth coordination of her body, like a piston engine coming up to full speed.

“C-cloudy… I’m… I’m going to...!” Anon suddenly yelped, the feeling of complete fullness bubbling up from his loins suddenly, the dull ache that had been building there quickly transforming into an explosive cascade of release. He’d never cum so fast - not from only three strokes! But this MILF’s pussy was just… on a whole other level! Each slide of her muscles over him, her raw heat… the damn musk she was hanging in the air.

He didn’t stand a chance.

Anon sighed happily and tightened his grip on the mare’s flanks, letting his hips twitch involuntarily as he prepared to unleash his fattest load of the night into Cloudy’s waiting pussy.

“Going to what?” Cloudy tsked, growling. “...you’re not doing anything, without my permission. And certainly not before I have been satisfied.”

Anon felt Cloudy’s vagina clench down, near to the entrance of her outer labia, tighter and fiercer than anything she had done before. It felt like someone had drawn a steel wire tight around his cock.

“G-gggaaaaaaahhh!” Anon shouted aloud, the sharp pain brutal. He felt his body pulse and jerk, once, twice, three times… as he dry-fired, his orgasm unable to erupt, completely closed off by the pussy-vise around his cock.

A ruined orgasm. Again.

But worse.

He gasped with desperation, trying to get his eyes to focus. His entire body was burning from the need to suck in oxygen. His dick felt like it was in a tesla coil, with multiple branching tingles arcing through every overstrained nerve fiber. His balls felt like they were going to explode - as they swelled and bulged with displeasure at their inability to loose their genetic payload.

“I told you I would be rough.”

“P-please!” The plea fell on completely deaf ears. Cloudy simply adjusted herself, maintaining the frighteningly powerful control of her cunt-muscles, simply grinning as she watched the human’s cock bulge and throb pitifully at the exterior of her pussy.

Throb after throb, as spurt after spurt of ejaculatory release, misfired in Anon’s urethra - backing up into his own gonads, swelling his fruit to pendulous size. Anon’s vision clouded, white tunnels of consciousness appearing around the outskirts of his vision, as he desperately tried to remain focus until, finally.... his constrained orgasm subsided.

“G-g-gahhhhh!” Anon took in a deep, gasping breath. Drawing oxygen for the first time since his non-release began. He felt the blood rush back to his body, his vision slowly returning with a midst of pinpoint spots appearing in his focus - sparkles of light that danced across his retina, belying just how oxygen-starved he’d become. Simultaneously, his whole body began to ache - his muscles, which had tensed so hard as they were captured in the throes of a ruined orgasm… his balls, which felt akin to the hoover dam after a massive rainstorm had passed through, with water dangerously splashing over the top of a crumbling barricade… and his cock!

He looked down at himself and was almost terrified by the sight of his manhood - swollen and reddish-purple, rigid and throbbing to tremendous size. The thing felt like he’d been stung by a swarm of angry wasps - he’d never felt so plump and full in his entire life! His whole size was comically jammed into the puffy pony pussy in front of him, like something out of an old looney tunes cartoon… except it was real.

“Now, let’s continue.” Cloudy’s purr was part growl, part giggle… and all sex.

“W-w-wait Cloudy, I’m not re-”

*SQUELCH*

With a grinding thrust, Cloudy slid onto Anon, fucking herself back up on his even thicker cock.

“F-ffff…..!” The syllable hung in Anon’s bitten lips, as the sensations of twisting heat returned to him. With his new swollen girth, it felt like he was expanding into every crevice, every nook, every cranny, every minute fold of the mare’s pristine vaginal depths, his flesh poured into her like some mixture between rock-hard rigid cock and liquid man-meat.

*SQUELCH*

But she hadn’t stopped there - immediately she’d reversed and recontinued her next stroke, slamming back with more violence and speed than before…. Still, the narrowness of her cavity at its ultimate depth prevented them from completely conjoining… but it felt like they were edging ever closer… Anon was surely but steadily mining deeper into her moist cavern.

*SQUELCH*

“Mmmngh.” This was the first grunt that seemed to escape the dominant, poised mare… not like any of the moans or groans she’d purposely let slip earlier… this had bubbled out of her like an escaping geyser - venting from the core of Equus’s fiery depths.

Anon’s focus quickly zoomed in on Cloudy’s eyes - the window to any mare’s soul. What he saw there was something that he would have loved to see… had it been any other mare.

She was losing control.

Anon had seen it so many times in his various erotic adventures since arriving in Equestria - the way A mare’s eyes would slowly change, pupils dilating, irises turning into those heart-shaped emoticons, a glaze falling over the usual shine of those large, cute, pony eyes The mare’s eyelids would roop slightly, her mouth would open ever so slightly, the tip of her tongue would start to wag, a faint sheen of musky perspiration would bead on her brow….

And then they would be completely fucking feral.
