Rarity 3

Glitter finally entered the bathroom and the moment she did she felt the intense heat coming from the shower envelop her entire body.

The Rarity in the bathroom was on the floor puking up loads of cum. The water running from the shower served as a convenient cleaning tool as it washed away Glitters seed, leaving nothing but a wet steamy atmosphere.

The other Rarity walked into the bathroom and shut the door behind her.

"I knew you'd like this little gift. It's a new spell I just learned from twilight, the 'double trouble' spell." Explained Rarity.

Glitter walked under the running water and soaked her entire body.

"So which is the real you?" asked Glitter

"They're both the real me. Anything you do to her, I can feel, and anything you do to me, she can feel. Rather than cloning myself I split my essence into two separate beings, so both are me and I am both" said Rarity.

Upon hearing this Glitter turned from the shower to face both Rarity's, as she looked at them, her limp dick began to stiffen up again.

"That thing is just monstrous. Think it can handle two ponies at once?" Asked Rarity

Without saying a word Glitter walked over to Rarity 2, who was still recovering from puking out cum and flipped her over so she was face down and her ass was sticking up.

She put her foot on her back and pushed her towards the flowing water. Rarity slid across the slippery shower floor with ease, ending up directly under the water with her head facing the wall and her ass facing Glitter .

"Let's see just how much punishment you can take." Said Glitter.

"Do your worst." Replied Rarity as she waved her horn and materialised a chair to sit on.

Glitter walked over to Rarity 2 and slung her giant cock between her ass cheeks. She let out a sweet moan as she felt the thick shaft nestled between her butt.

"Eep" Rarity felt exactly what Rarity 2 was feeling, she braced herself for what was about to come next.

Glitter pulled back,and with the water pouring down on both of them acting as a makeshift lube she plunged her cock deep into Rarity 2's ass.

The impact was so forceful it shot Rarity out of her chair and into the air, both of their moans filled the shower room as they tried to keep themselves composed. Rarity began to float in the air, as if suspended on a giant invisible cock.

"W-what are you doing? That's the w-wrong h-hole. T-t-take it out, NOWWW-" Rarity's scream filled the air as Glitter began to pound away at her ass, completely ignoring her.

"This sensation, who knew a prissy little pony like you could feel so good." Said Glitter as she continued her piston fuck.

Rarity, still suspended in the air began to violently jolt up and down as if an invisible entity was plowing her with immense force.

"G-g-glitter… you h-have to s-stop… I can feel it in my b-belly…"

"Good! Now feel it in your throat!!" Glitter grabbed Rarity 2 by the waist and picked her up, but Rarity 2 had no strength to even lift her body up, so she dangled there like a ragdoll, it seemed she was no longer conscious, or at least no longer in her right mind.

Glitter thrust even deeper into Rarity 2, and began fucking her even more violently than before.

The lewd sounds of skin on skin clapping resonated through the steamy shower room.

"I-I can't… she's gonna kill me, but it feels so good!" said Rarity.

Glitter was now using Rarity 2 as nothing more than a walking fucktoy, evident by the fact that she disregarded her well being. Her cock thrust in and out, over and over, squelching and slopping inside her.

Glitter grabbed Rariry 2's hair and pulled her head back to reveal her face in pure ecstasy. A pony who was once the very embodiment of elegance and grace now defiled into nothing more than a mumbling, drooling, cock-hungry slut, who's face betrayed everything she stood for.

Her eyes rolled back in her head as all common sense left her brain.

"I-is that the b-best you've g-got?" said Rarity 2, struggling to get the words out while still being fucked.

"You idiot!! W-what the fuck are you saying, she'll destroy us!" exclaimed Rarity.

Hearing this caused a switch to flip in Glitter. She pushed Rarity 2's face against the wall with immense force, cracking the tiles and causing the entire room to shake.

With all the strength she had she thrust her cock deep into Rarity 2, deeper than she'd ever gone before, then pulled the entire length of her cock out leaving only the tip inside, and thrust deep into her again, doing this over and over again.

The moans of both Rarity's resonated through the entire shower room. Glitter then kicked it into second gear and plowed Rarity 2 vigorously, not letting up for even a moment.

"I-I think… you're g-gonna… break s-something inside…" Rarity, still suspended in the air, struggled to get her words out as Glitter continued her violent thrusting.

"Good! Now taste my cum through your ass you prissy little slut!" Glitter's cock seemed to gain new life and grow an extra few inches the moment she said this.

Her cum gushed out of her cock into Rarity 2's ass like water out of a fire hose, shooting straight into Rarity 2's stomach. The sound of overflowing cum could be heard even through the running water and intense moaning.

Glitter continued to thrust back and forth as her cum left her and found its new home inside rarity 2. Glitter released Rarity 2's hair and wrapped both her hands around her neck, squeezing her throat tightly as she used her giant cock to skewer her.

The intensity of the thrusts got more and more violent, with Rarity 2's face still pressed against the wall, she began gasping for air as she was being choked out. Glitter could practically see her cock digging through Rarity 2's spine.

Then as if on cue, an eruption of white seed came blasting out of Rarity 2's mouth, as she began to projectile vomit Glitters seed all over the wall and floor. It came shooting out of her at immeasurable speeds, and when her mouth was unable to accommodate the amount of cum that was flowing out of her, it began to leak from her nose too.

Glitter could hear Rarity behind her struggling to keep her composure and after a few more thrusts Rarity let out a "BLERGH!!!". Cum came bursting out of Rarity's mouth, as she too began to projectile vomit ridiculous amounts of cum. It gushed out like a broken fire hydrant and painted Glitters hair and back as it left Rarity's mouth.

Somehow the cum Glitter was pumping inside Rarity 2's stomach, transferred over to Rarity.

The once glistening shower room, was now transformed into an unrecognisable cum container. The tiles on the floor could hardly even be seen anymore and the water served no use to wash it away, Glitter's cum was clearly the dominant force here.

"What the fuck? How the…?" Glitter was clearly confused as to how this was happening but it just served to make her even more hornier as she continued to pump more and more cum inside Rarity 2.

Glitter turned to see Rarity floating in the air, her ass hole stretched out like she was suspended on an invisible shaft and her mouth spraying cum all over.

Glitter grabbed her and pulled her in, placing her on top of Rarity 2's back. The cum didn't stop, and neither did Glitter's intense thrusting. Glitter grabbed the back of Rarity's neck and pulled her in for a deep kiss, swallowing her own cum as she did so.

The sloppy sounds of sucking and slurping filled both their mouths. Rarity bounced up and down as Glitter didn't stop fucking Rarity 2 even while she was engaged in a deep sensual kiss.

After a few more seconds Glitter pulled away letting out a lip-smacking "pahh" as the suction of both their lips were released.

Glitters own cum began to pour out of her mouth like milk out of a milk carton and down into Rarity 2's ass, serving as lube to oil Glitters cock each time it thrust in and out of her.

Glitter felt all the energy leave her body and she was unable to hold the two up any longer. She fell back and they all collapsed to the floor.

Rarity was now mounted on top of Glitter, and Rarity 2 who was practically moments away from death by cum, was forced deeper into Glitters throbbing cock as she fell back onto it.

This sensation caused both Rarity's to let out deep intense screams, all while Glitters cum was still flowing out of their mouths, not as intense as before, but rather as a steady stream. Rarity could practically feel the cock in her throat.

Glitter had passed out but her cock was still very much active and it began another round of blasting out cum.

Both Rarity's sat up straight, with their backs to eachother, they tilted their heads back in unison and an absurd amount of cum shot out of both their mouths.

From a third party perspective they could be mistaken for a sculpted fountain, as that was exactly what the scene unfolded into. Two ponies looking up, with gallons of cum spraying out of their mouths and filling the room like a cum fountain.
