The Mantiwhore

With the manticore's balls and majority of his cock being tended to by Rarity and Twilight, Fluttershy was left to try and wrap her lips around his impossibly large tip. Not wanting to waste any more time than necessary Fluttershy, almost eagerly, opened her mouth and started to squeeze the head of his cock inside, slowly claiming more of more into her wet warm maw. Fluttershy closed her eyes and focused on getting as far as she could before she couldn't go any further, the soft yet coarse texture of the manticore's package almost seem to scrape again her silky delicate tongue. The taste was interesting, it was different but also strangely familiar, she didn't mind it at all, in fact she even dared to think that she actually liked it. Eventually Fluttershy had somehow managed to fit the whole tip in her mouth as her lips closed slightly upon breaching the ridge that separated the tip from the rest of his cock, as she opened her eyes she could see Twilight's magic almost touching her face, mere millimeters away before it went back to the base to continue stroking, Fluttershy was actually rather impressed with herself.

Confident that she could take no more and not wanting to risk hurting herself or getting the trademark barbs of cat cock in her mouth, simply starting sucking despite not being capable of much movement, the manticore still seemed to be enjoying the each of their ministrations and was just purring louder and louder in appreciation. Meanwhile Pinkie Pie and Rainbow were watching by the sidelines feeling a bit like third wheels, they told themselves that they weren't needed rather than saying to themselves that they felt left out, if they said that they felt left out then that would imply that on some level they wanted to sexually pleasure the manticore. They were pleasing the manticore out of necessity, not want. It was just as Rainbow decided that this would be a perfect time to take a nap that she suddenly gasped when a hoof started rubbing away at her pussy which even she herself didn't realize had become undeniably moist. Pinkie giggled at Rainbow's reaction, "Does that feel nice Dashie?"

Rainbow grunted and said "Nngg... well yeah but... o-oh fuck... why are d-doing this?"

Pinkie rolled her eyes and said "For fun silly!"

A few seconds passed with Pinkie furiously rubbing Rainbow's pussy, before Rainbow Dash bit down on her lip and began squirting her feminine fluids all over Pinkie's hoof. Pinkie kept rubbing, albeit more slowly, before she said "You came already?"

Rainbow adopted a stern look in Pinkie's direction and said "It's been a while! Alright?!"

Pinkie removed her hoof as she said "Geez Dashie, you need to get laid more often, build up some endurance".

Rainbow Dash said "Yeah well, I guess I'm just too fast or whatever, like you could do any better!" Rainbow Dash realized she had somewhat misspoke there as Pinkie put on a mischievous grin before forcing Rainbow to lie on the ground and instantly sitting on her face with her squishy pink pony pussy pressed right up against Rainbow's muzzle.

"Lick" said Pinkie. Rainbow Dash didn't see what else she could do in that situation and just obeyed, indulging in the tangy taste of her friend's fuck hole. Back at the manticore things were progressing decently, Twilight was now pumping his cock at a faster rate and Rarity had gone from just fondling the balls to actively squeezing them a little, Fluttershy meanwhile had gotten accustomed to have something so large in her mouth and was now moving hear head back and forth while she sucked. The manticore was thoroughly enjoying itself as a strong orgasm started building, it wouldn't be long before he'd cum and feel the relief of going from very heavy cumbersome balls to thoroughly empty non-aching balls. Now that Fluttershy was sucking comfortably, she felt a little braver than before and decided to see just how much more of this massive member she could take and started to actually slowly walk forward as she worked more and more manticore cock down her throat, Fluttershy gagged and cough but pushed on with a sense of determination while Twilight shifted the focus of her magic accordingly to make way for Fluttershy's face, Fluttershy finally reached her maximum limit as the manticore's cock seemingly hit some kind of barrier deep in her gullet just where the first barbs of his cock had slipped in just past her teeth.

While Fluttershy kept up her sucking Twilight was jerking off the manticore so hard that had she not been using magic, there would almost certainly be friction burns, Rarity was now actively tugging on his overgrown cum sacks, both unicorns putting all their effort into making the manticore cum. Pinkie meanwhile squealed as her pussy clamped down on Rainbow's muzzle and soaked her face, Rainbow just licked her lips once Pinkie removed stood up and said "Whewee Dashie! You eat pussy like a champ".

Rainbow Dash chuckled and stood up saying "Yeah, thanks Pinkie".

Fluttershy felt just how much the manticore's cock was throbbing and guessed he was about to cum, however a rather troublesome obstacle made itself none as Fluttershy attempted to move backward and in turn get the enormity of dick flesh she had inside her back out into the open air, the barbs. The barbs were stuck behind Fluttershy's teeth and preventing her from moving backwards to pull herself off, by the time this problem was realized she was far too late to get Twilight or Rarity to help, the manticore was cumming. The manticore let out a loud roar as cum burst forth out of his cock and directly into Fluttershy's stomach, Twilight kept up her pumping and Rarity her squeezing, ensuring that the manticore ejaculated liters of his seed, Fluttershy's insides struggled to hold such copious amounts of semen as her stomach began to balloon outwards, giving her the appearance of some pony who was heavily pregnant.

When the manticore was spent, his balls having shrunk, his cock softened and shriveled until it was small enough that the barbs were no longer an issue and his member elegantly slipped out of Fluttershy's mouth, allowing her to jettison several pints of spunk from both ends of her body. Once her body had finally stopped ejecting the excess fluid it failed to contain, The manticore picked up Fluttershy and started licking her head in appreciation, almost with a smile, as his sandpaper-ish tongue scraped against her skin and forced her hair to stick up from the exposure to such thick layers of saliva. Every pony smiled, it seems the manticore was happy and distracted enough to let all of them pass, Twilight stopped for a moment as the manticore set Fluttershy down, allowing her to follow the others in a cum-filled waddle kind of way, Twilight said "How did you know that the manticore was so... er... pent up?"

Fluttershy smiled in a somewhat cum-drunk fashion and with a shaky voice she said "I didn't, sometimes we all just need to be shown a little kindness". Twilight smiled, though she thought to herself that helping a manticore deliver its payload was perhaps being just a little too kind.

As they left Nightmare Moon rose out from the manticore's body in smoke form before assuming her pony form briefly to look at the manticore in disdain, "You were useless!" The manticore growled at her before swiftly pinning her down to the ground as the testosterone in his body brought him back to a full erection, Nightmare Moon's eyes widened in fear, "NO NO NO!"
