Maximus knew the drill whenever a human girl presented herself like that and immediately became strongly erect. Rarity couldn't believe she was about to allow herself to be impaled on such an enormity of cock, but it had to be done apparently. Maximus moved forward and roughly pressed the tip against Rarity's exposed hole, suffice to say that Maximus was not a gentle lover, when he fucked, he FUCKED. Rarity let out a silent scream as suddenly untold inches of thick veiny horse dick were rammed inside of her, she looked down to see her stomach bulging out obscenely from the sheer ridiculous length that Maximus had in between his legs, despite already having ripped through her hymen and pushed up against her cervix, he kept going.

Rarity groaned as she felt her inner most entrance stretched far beyond the furthest point that it would ever need stretch as Maximus forcefully slid his length in her womb, she had truly been deflowered in the most violent way possible. When Maximus could finally no longer proceed, Rarity looked down and was horrified to see that the outline of his cock had now gone from her stomach ti right in between her tits, she wasn't even sure how that was physically possible. However, all of those questions and indeed much of her cognitive functions disappeared when Maximus started thrusting, his thrusts were not starter thrusts that were slow but firm, they were thrusts that rocked Rarity's body back and forth as Maximus tried to, as quickly as possible, release his seed inside her.

Rarity just made unintelligible noises that were a mix of pain and pleasure and everything inbetween, the unfortunate thing about Maximus was that because he started off so strong, he finished very quickly. To Rarity's great surprise, after about a minute or two of the most violent sex possible, Maximus began to blow his load inside of her, completely flooding Rarity's womb with thick hot stallion cum. Rarity's stomach swelled as his nuts continued to pump more and more spunk into her before finally stopping, her stomach bloated with semen with a cock that was bulging in between her generously proportioned tits. Rarity's eyes were crossed and she was drooling, she whimpered as Maximus began to pull out, he struggled a little at her cervix, but after a large tug his cock finally slipped out of her entirely and her stomach began to go down, shrinking as the copious amounts of horse spunk practically gushed out of her pussy.

It was short-lived, but as a breeding stallion, it was all Maximus knew in regards to sex. After Rarity had regained her energy, she made the unfortunate mistake of attempting to get up by first rolling onto her front and putting her legs down on the floor, putting her in the doggy style position that signaled to Maximus that it was time for round 2. The other unfortunate thing was that this time around, Maximus moved forward but his aim was slightly off, which is why Rarity let out a yelp and then groaned fiercely as Maximus rammed his impressive package up her ass. Maximus, just as before, pushed every single inch of his dick that Rarity's body could take inside, Rarity could feel that the bulge had gone between her tits and was practically at the base of her throat before Maximus finally bottomed out in her... well, her bottom!

Maximus was much more aggressive this time and Rarity's ass cheeks wobbled like two bowls of jello as he slammed his dick into her ass with wild abandon, borderline wrecking her body with his eager pounding. Rarity's body had gone numb in an attempt to dull the pain and cope with the sudden feeling of being completely full of horny horse dong, again, she didn't have to wait long before her belly started inflating once more, Maximus just filling her to the brim with pints upon pints of warm equine jizz. When it was finally done, Maximus found pulling out much easier and the floor was once again painted white as Rarity's ass expelled the excess horse fluid that had been squirted inside it. At this point, Rarity figured "Why quit there?", every hole on her body was tight, it hadn't been broken in yet, which is why Rarity turned around, got on her knees and before Maximus got any softer, pushed the head of his dick in her mouth and started sucking, encouraging him to fuck her throat.

This feeling was new to Maximus, but he liked it. Being a particularly large horse meant that he had at least one more full load to offer, so with a loud whinny he started feeding Rarity his big bitch breaking baby-cream machine and started fucking again. Rarity was actually conscious enough to realize the Maximus was so long that the head of his pony prick was actually in her stomach, her throat was being stretched out beyond what was healthy and she was struggling to breath, her face was turning various unhealthy shades of red, blue and purple and eyes flowed down her face. Rarity's belly was put through the final test of its stretching capabilities as Maximus fired his largest load yet straight into her stomach, her belly practically ballooned outwards giving her the appearance of a woman who 8 months pregnant before Maximus finally stopped cumming, Rarity was just on the cusp of passing out from oxygen deprivation when Maximus, being completely spent, pulled his dick out of Rarity's mouth, allowing her to vomit a decent quantity of his final load of baby batter onto the floor, partially choking as she simultaneously took great big gasps of air into her lungs.

After it was all over and Maximus had nothing more to give, she looked exceptionally fat and round after having at least a liter or two of horse cum pumped into her body, but not only that, every single hole was suitably stretched out. Rarity could only hope that Twilight's method had really worked the way she said it would, after all she had both orgasmed several times and damaged the inside of her body without really noticing it, her body was too busy just registering such a gargantuan male invader. Rarity suddenly noticed Twilight looking at her with an almost dreamy look on her face "You all done there bitch?"

Rarity simply nodded and said "Uh-huh..."

Twilight smiled and said "Good, now you get yourself home, give it a month or two so that your body can adjust and sort itself out from the ordeal you just went through and before you know it, guys will be selling their fucking organs on the black market just for the chance to worship those milk melons you got hanging off your chest, seriously though, you're quite busty. I like them, I wish I could motorboat those fat tits, but you're a bit of a prude and I'm far too crude, so whatever". Rarity put on her clothes, which after that she didn't care would no doubt get all sticky from the cum still seeping out of her orifices, she was just anxious to experience the effects of Twilight's "help".

-5 months later-

Rarity came as her boyfriend gave his last powerful thrust into her pussy, gritting his teeth as her pussy clamped down on his pulsing dick, milking his balls for all they were worth.

"Boy Rarity..." he said "Your pussy is to die for, your previous boyfriend was a lucky guy"

Rarity chuckled a little as she said, "Well, my previous lover was a bit too much of a farm boy for my tastes, you my dear, are exquisitely more delicious" then pulled him into a kiss. After Rarity's boyfriend left her home, she reminded herself that she had to thank Twilight at some point for her rather unorthodox way of getting men to finally fuck Rarity. Then she thought for a moment, surely the perfect thank you would be a little bit of..."girl time".

The End.
