Aloe and Lotus sat in front of Rainbowdash, their faces a few inches from hers.
 
"So, which one of us shall it be?" they asked in unison.
 
"Uh, what do you mean?" Rainbowdash asked nervously.
 
"Which one of us do you want?" the twins said, each stroking one of dash's legs.
 
Rainbowdash hesitated. They both were sexy. Rainbowdash's brain started to melt.
 
"I- I-"
 
The sisters shared a look (a sexy look). "That's ok, miss Dash. You can take your time."
 
At that same time, Aloe started to dip down while Lotus grabbed Rainbow's face in both hooves. Rainbowdash twitched.
 
Suddenly, a strong sensation came from her crotch. (You know the one) She only had a few moments to moan in pleasure before Lotus' blue lips connected with Rainbow's. They shared a deep kiss in uncontrollable blue lust. (Whatever that means)
 
Rainbow broke the kiss and held Lotus tightly.
 
"Ah! I pick you!"
 
Lotus smiled again. "Very well, miss Dash."
 
Aloe rose up, now doused in more liquid than before. Lotus gave her a nod. Aloe smiled (sexily). Her mouth opened wide. Wide enough for a pony to stick their head into...or...
 
Lotus placed both hooves in her sister's mouth, letting them slip down into her throat. Allowing Aloe to finish her work, Lotus slipped in past her head and shoulders.
 
To say that Rainbowdash wasn't pleasantly confused would be as valid as the reader deems it.
 
Lotus was now down to her hips in her sister. Aloe snaked her tongue underneath her sister's belly, and right into the flower pony's pony flower. Lotus moaned in pleasure inside Aloe as her sister stroked her marehood. It was short lived though, and Aloe left Lotus in sexual frustration as she slipped further down her sister's throat.
 
Only her hooves remained outside her sister's lips. Aloe turned towards Rainbowdash, putting her face right in front of Rainbow's. The blue hooves dangling out of the pink lips grazed Rainbow's lips, making her shudder for a moment. Aloe's eyes struck Rainbowdash, inviting her to play.
 
And Rainbow accepted. She licked the hooves in front of her, covering the length in saliva. She wrapped her lips around the hooves, sucking them deep into her mouth until her lips connected with Aloe's. Rainbow's eye's widened a moment. In her hesitation, Aloe swallowed again, finishing off her sister. Rainbowdash watched Lotus's hooves slip down her sister's throat. Her face was only inches away from slipping down herself.
 
"If you want her...come and get her~"
 
Rainbow complied all to quickly. Within moments her hooves were already sinking down Aloe's throat, following the blue spa pony's path. Aloe's sweet breath rolled over Rainbow's cheeks (how?) as her head entered Aloe's mouth. The warmth all around her spread to her back and sides. Rainbow squealed in pleasure as Aloe's saliva ran down her ass. Aloe's lips started to stretch over said flanks, spreading her body's warmth down there. Wait a sec, Rainbowdash still had a dick! That made it just about impossible for Aloe to finish her work...unless...
 
Aloe's tongue snaked around Rainbow's obviously hard cock. Her slightly rough tongue rubbed up and down the length of the shaft, slowly at first, then progressively faster. Rainbow made a noise, but it was hard to describe. The Rainbow's horn spewed it's magic sparkles, leaving its owner limp in Aloe's maw, twitching every once in a while.
 
Aloe, lifted her head back, allowing the other blue pony slide down her throat, unimpeded by nosy thorns. Rainbow's legs slid deep into Aloe's throat, leaving her hooves to rest in the cooler air. Aloe rubbed her tongue around her hooves, wetting the sides and soles of them in her saliva. When she couldn't take anymore, she swallowed one last time, taking Rainbow's hooves into her throat, disappearing behind the wall of flesh.
 
Rainbowdash found herself in the tight, hot space of Aloe's stomach. Lotus sat waiting for her in the cramped space. Rainbow was pushed out onto Lotus, stretching out the walls of their prison. Lotus looked into Rainbow's eyes (but it was hard to tell because it's dark). Rainbow smirked as her ponywood started to ponyharden again. Time for round two.

Rainbowdash strode out of the spa feeling nicely refreshed. The bath was simply luxurious, the aromas tantalizing, and the massage paralyzingly relaxing. Oh, and the sex was good.
 
Aloe and Lotus waved back at her, telling her to come again "soon." They held their smiles until Rainbow finally flew off. Then the plastic melted of their faces.
 
"Gueh! I'm telling you sister, I cannot take any more of this!"
 
"I know, but our clientes come first."
 
"That's easy for you to say, you don't have a layer of your sister's saliva underneath a layer of your customer's!"
 
Lotus shivered a moment. The saliva and stomach acid worked into her fur really weighed her down.
 
"Do not worry sister, I shall...get the next one-"
 
"Good" said a different voice "because your next customer is here."
 
The spa ponies turned around. There was Twilight with a blind fold, a whip, and a bucket.
 
Aloe fainted.
