> it's another wonderful morning at the Spa.
> Aloe is busy running the register so you're to open the doors and greet the first appointment.
> they've been coming earlier and earlier lately.
> you're pretty sure you know why.
> you open the door and smile brightly at both Rarity and Fluttershy, who are politely waiting.
> they're also very pregnant.
"Oh, good morning to you both! Come in, please. Right this way."
> it's slow going, Rarity very carefully slips through the door.
> Fluttershy even wobbles on her hooves and blushes when you offer her a guiding hoof.
> even several months in and they're not use to the weight.
> "I do believe Fluttershy and I would adore a massage. With those wonderful oils you used last week."
> Rarity only occasionally even acknowledges she's pregnant. The weight must be a hangup.
> Fluttershy just goes red at the slightest reference.
"Oh of course! I will grab the tray, make yourself comfortable in the main room."

> by the time you return with the tray of massage oils the two have settled on the upraised tables.
> you overhear them talking, not realizing you're just around the corner.
> "it's not fair to him, Applejack or really their whole family. They should know. We did ask him to..."
> "I won't hear of it Fluttershy. The scandal would be...dreadful. I know you've been always partial to...him, but consider my situation as well. It's better we keep this indiscretion quiet. For the sake of our children."
>"But they should know their father, Rarity."
> You've already heard enough gossip to last months. But if you wait longer you'll be discovered.
> You make a show of loudly coughing and wheel the tray into the room.
> whatever Rarity was about to say is quieted at your entrance.
> You smile, on autopilot as you connect the dots of the last few months.
> A year ago Rarity had confided she'd always wanted to try a threesome. And her birthday was coming up.
> now you even knew the truth, and the father.
"So then. I believe that you had the massage first, miss Fluttershy. If you don't mind I believe it will be Rarity today."

> They don't disagree with your idea but you didn't think they would. Just polite to ask.
> you slather your hooves up with the slick oil.
> it's something of a challenge to stumble over without smearing the floor but you manage to slide up next to Rarity.
> she's laying on her back, her huge swollen stomach exposed
> fur helps, but you imagine that Rarity has been asking for these massages on her belly to avoid stretch marks.
> gingerly you place your hooves on her stomach and marvel at the tension.
> Rarity jumps a bit and then nervously laughs.
>"it wasn't you. The uh..foal just kicked."
> You smile, always a fan of kids yourself. You begin massaging and half hoping you'd feel a kick yourself.
> There! Rarity jumps, but you catch the feeling of a soft little hoof meeting your own from inside her womb.
> You resist the urge to melt and coo like any mare does when faced with foals that don't belong to her.
"Oh my, a very early riser here I think. Do you have any idea if it's a filly or a colt?"
> Rarity bites her lip and blushes.
> but not in a particularly good way. You may have touched a problem area.
> "I...have not. I've been still very busy to be honest. I could ask Twilight to look with magic but I suppose I'll learn eventually right? "
> You laugh for her sake, smoothing over that you're dealing with a mare not really prepared to be a mother.
> Fluttershy has been watching and had warmly smiled when you asked your question.
> "I know! It'll be a little boy. A earth pony and...well, he's really growing fast. So much like his father..."
> she mumbles the last part, which you still heard. Fluttershy had been affectionately rubbing her own stomach.
> at least she was happy where she was

> normally you'd start asking about names and baby shower plans.
> but Rarity looks uneasy. Especially when Fluttershy alluded to the father.
> you concentrate on the massage.
> there's a lot of stomach to slather with oil, and soon Rarity's pristine white coat is slick and matted.
> she settles in and sighs while you attend to your work.
> you smile at just the notion that you're playing with the baby.
> it keeps kicking around where your hooves go.
> absently you slip a bit lower, lower than you usually would go.
> the stomach is throwing you off.
>"oh, uh. De-ar!"
> Rarity squeaks just when you realize how close you were to becoming like a very different sort of massage parlor.
"My mistake, aha. I am very sorry."
> embarrassed you rise far up along her stomach and redouble your hooves circling.
> Rarity is red faced but then laughs it off.
>"Oh, not to worry. I suppose that's the most action I've had there in quite awhile. "
> you laugh nervously and studiously refuse eye contact.
> it's bad enough when the stallions roll over and expect a 'happy ending'
> Aloe would kill you if the mares started to expect that too
