"So much has happened, why in the fuck didn't I try harder?!?" Rainbow dash says, thinking out loud as she walks down the alleyway, true at this time of night it was dark and spooky, but it was Now her new jobsite, since she had failed the wonderbolts test she had been working through the night just to make enough bits to get by, and with a quick glance she saw her first customer.
"It's fifteen bits, you got that?" She says to the stallion who had hidden himself behind the dumpster.
"Yeah, right here." he replies, turning his head and grabbing a small pouch with his teeth from his saddlebags, tossing them to Rainbow dash. In the moon light she had seen he was a unicorn, and wasn't very big.
She opens the bag and counts the bits, sure enough they were all there.
"Lets begin" she says, the stallion coming up behind her, preparing to mount.
With one quick motion he was raised up, the tip of his flared cock pressing against her warm slit, but the moment he had began to thrust in she knew something was wrong.
"WHAT THE FU-" she tries to call out, but was cut off by the pain rolling inside her.
The cock that had begun to slide inside her was absolutely massive, and was stretching her opening well beyond its limits.
"You made one little mistake miss, you decided to service the great Noteworthy!, now your all mine!" With this the stallion rams the remaining foot of his massive cock into rainbow dash, who screams in pain.
"P-please stop!" She cries out, tears streaming down her muzzle, which was grimaced in pain.
"Don't worry, I'll stop eventually, but first I'm gonna have some fun with you" Noteworthy replies, starting to buck back and forth, rainbow dash crying out with the rhythm.
"I was passing through town and got the most amazing idea, why don't I knock a mare up?, at least I won't have to worry about the foal, it wouldn't be my problem " he says between movements.
"P-please don't, i-I don't want a foal!" Rainbow dash almost grunts out, the pain clouding her mind.
"Ah, to bad!, by the time I'm through with you you'll have ten of my fillies growing in your stomach, won't that be nice?"
"No!"
"You ain't got to much of a choice miss, now stay quiet or I'll gag ya!"
With this Rainbow dash knew she didn't have much of a choice, noteworthy's massive cock was buried deep inside her, and by the slap of his balls she knew they were massive, hitting her almost on the ankle.
Even though she hated it, this rutting was actually getting her off, and within 5 minutes she could feel herself about to climax, her insides already squeezing hard against Noteworthy's member, as if trying to milk it, but even as she orgasms several times he didn't show any sign of slowing.
As he continued it began to get less and less painful, and more and more enjoyable, and by the time he was showing any sign of slowing she had begun to love the feeling of his massive, rock hard member buried deep in her womb.
"Ah-ah, IM CUMMING!" He yells out, his massive flared tip flaring even further as the first spurt entered her womb, followed by another, and another, all bigger than the one before.
Soon her stomach began to bloat outwards, but he didn't show any sign of stopping, but rather continued to pour pint apon pint into Rainbow Dash's womb, who had once again come to a orgasm.
Pretty soon her stomach had swelled to the size of a basketball, the skin taught and with every burst it only got tighter, until it looked like it would burst, but somehow it had held.
"Surely I've only begun!" He says, thrusting his cock deeper into her cum bloated uterus, not even a drop seeping past his mid ring.
Rainbow dash couldn't reply, had been sucked into the throws of ecstasy as she rode out her sixth orgasm in the last two minutes, her tongue hanging out of her mouth, her eyes unfocused.
It seemed that the river of spunk he produced would never end, Rainbows stomach was the size of a large beachball, and was only expanding further with every drop of cum he pumped into her, until it actually raised her partially off the ground, only her front hoods still touching.
Once he had finally stopped cumming he pulled out, and with out his member to stop the flow the spunk in her stomach began to leak out, slowly and steadily.
"Ah, nothing is better than bloating a mare, now if you excuse me, I must be off" Noteworthy says, picking up his saddlebags where it had fallen of him, and left, but not before snatching the pouch of bits from beside rainbow Dash, who was laying down the best she could, lightly moaning.
"Rainbow, what happened out here?!?" These were the first words she hears as she awakes to a familiar face, Twilight Sparkle, who had heard moaning and saw a shadowy figure run from the alley, and had decided to check it out, only to find a cum-bloated Rainbow Dash that had obviously been through a lot, and obviously needed medical attention.
"Hospital" was all that Rainbow Dash could get out, and in a flash twilight teleported them to the nearest one, hoping that whatever had happened to Rainbow hadn't hurt her.
As Rainbow Dash recalls the story to the nurse Twilight was appalled about what had happened, and when Rainbow Dash saw the doctor he ran some tests, it turned out she would be OK, but she wouldn't be able to fly for awhile, unless she could carry six foals at once.
