After following Rarity, Glitter stood just outside the door to her bedroom, silently watching.
"It's her fault I'm like this, the least she could do is help it calm down." Glitter said as she began to stroke her cock.
Rarity was none the wiser, she undid the single button holding her nightgown together, and it cascaded off her body and slipped onto the floor.
Her entire body was laid bare for Glitter to see, her slender curves paired with her round plump ass and her huge breasts, were the embodiment of the perfect figure.
Although she had no idea she was being watched, the way she moved was almost overly seductive. Every simple gesture she made caused Glitter's cock to throb.
Rarity bent down and picked up her nightgown from the floor, giving Glitter a first class view of her ass.
Usually bending over like that would reveal everything, but Rarity's ass was so thick, all that was visible were two round ass cheeks pressed together.
"Oh fuck" said Glitter.
Rarity elegantly made her way into her en-suite bathroom.
"No not yet, I'm so close" Glitter decided to take the risk and follow Rarity.
She snuck into the room and tiptoed to the bathroom door. With her back pressed against the wall she waited to hear the sound of flowing water, and after a few seconds the water began running.
Glitter approached the door and pressed herself up against it, allowing her to peek through the small opening while staying hidden.
Rarity had an open bathroom layout, similar to gym bathrooms, but in a much more formal and pristine manner. There were no shower curtains to shield her from prying eyes
Rarity walked beneath the running water, feeling it cascade off her voluptuous body. This was enough to set Glitter off, she began stroking herself to the blissful sight of Rarity's wet body.
"I'm so close, stay right there, just a little more." Glitter said out Loud, in the heat of the moment she'd forgotten she was supposed to be quiet.
"Fuck, I'm gonna cu-"
"Tut tut tut, you wouldn't do something as savage as masturbate in secret like a perverted pony to the sight of your best friend's wet naked body now would you?" Rarity grabbed Glitters cock from behind and plugged the tip with her finger, stopping Glitter from cumming.
With Rarity's tits pressed against Glitter's back, paired with the firm grip she had on her cock, Glitter was both aroused and confused, how could someone she was looking at also be right behind her.
"What the? Rarity how did you-"
"Shhh… if you're too loud she'll notice" whispered Rarity into Glitters ear.
The soft vibrations of Rarity's voice echoed through Glitters entire body, causing her cock to jolt slightly.
"Here let me help." said Rarity as she began to stroke Glitter.
The two stood outside the bathroom door, with Glitter pressed against it and Rarity pressed against her.
"Look at the way the water just rolls off of her fat ass, you wanna fuck her don't you?" teased Rarity.
She began stroking faster, making the sloppy sounds of Glitter's cock being stroked, echo through the hallway.
"Oh my stars, it keeps getting bigger and harder, I can't even fit my hand around it anymore." thought Rarity
The Rarity copy in the shower began lathering herself up with soap, accentuating her sexiness even more.
"That's it, put some soap on those titties. Dammit Rarity you're so hot" said Glitter
Rarity slid her other hand under Glitter's arm and grabbed her cock with both hands.
"Think you can paint her big slutty tits from here?" Asked Rarity.
Rarity did one long stroke, all the way to the tip of Glitters cock, then in one fast fluid motion, pulled back all the way to the base of the cock.
"Oh shit! That's so good… go faster" said Glitter.
"Faster huh? Well let's see you handle this…"
Rarity performed the same long stroke only this time she did it 10 times faster. The loud sounds of clapping echoed through the entire house, over and over again as Rariry attempted to wring Glitter dry.
"I can't hold it anymore" said Glitter
"Great Pegasus, I can feel her cum building up in my hands, it's gonna shoot out like a rocket" thought Rarity
Rarity pressed herself against Glitter even more, causing her cock to slide through the small peek in the door, this alerted the other Rarity in the shower.
As she turned around, all that was visible was a huge thick cock standing as straight as an arrow, and a pair of small hands stroking it violently.
"Oh my…" said Rarity
Without hesitation Rarity approached the disembodied cock, got on her knees, opened her mouth and pushed her head onto Glitters cock.
"Look at that, she's telling you to turn her into a cum toilet, are you just gonna stand here like a loser, or are you gonna pump your pony potion into her guts." said Rarity, still stroking Glitter.
"Oh fuck this, I can't hold back anymore" Glitter stuck her hand through the door, grabbed Rarity by her horn and pulled her in with immense force.
Glitters cock slid straight down Rarity's throat with ease. The moment the tip touched Rarity's insides, Glitter let out a huge load, spraying and spurting into Rarity's stomach.
"That's it baby, fill me up, turn me into a cum dumpster" said Rarity
Using both her hands Glitter grabbed Rarity's head and shoved her even deeper onto her dick, her nose touched Glitter's stomach but Glitter didn't let up, instead she pulled back a little and started fucking Rarity's throat while still cumming.
"This feels so fucking good, I can't stop cumming!" Exclaimed Glitter
"Then don't stop, use her till you're satisfied." said Rarity. "Wow I can still feel your cum pumping out of your cock. Such a strong pony aren't you"
"You talk too much" Glitter turned her head, grabbed Rarity by the hair and pulled her in for a deep intense kiss, shoving her tongue into Rarity's mouth as the sloppy slurping sounds gathered around the pair.
There Glitter was, nestled between two sexy Ponies, one exchanging spit and lewd sounds with her, while the other passionately drank her overflowing seed.
