You’ve been working for Miss Rarity since you came to this odd land, populated by these creatures who are like the horses from your own dimension/timeline/planet/wherever you came from. The first thing you stumbled upon was this building shaped like a carousel. Rarity was the first pony you met, and she caught your eye immediately. Her pearly white coat with her shiny purple mane and tail, she just beamed with elegance as you walked into her boutique, with her red glasses and a measuring tape draped around her neck, staring at a mannequin shaped like a pony.

You two became fast friends as she learned what hands could do for her work, and threading needles with fingers (even your clumsy ones) was much easier than with her magic, weirdly enough. As you were now staying at her place, which turned out to have an entire office building below the ground level, you thought you would start working for her as repayment for lodging, food, and her making you clothes, since there weren’t any Gaps in Equestria.

But you never expected another part of the job, being Rarity’s right-hoof man. One morning, as you made your way into the bathroom to start your day, you ran into her doing something odd. She was…masturbating? But not in the…female way. As it turns out, Rarity was part of a small group of unicorns that had both sets of genitalia. So, in addition to her normal parts, she had an addition.

In sharp contrast to her white fur, she had a set of deep, ebony testicles larger than your own, about the side of large oranges. In fact, her whole sheath was the deep black, with a pastel-pink horsecock that slinks out in times of…excitement. It was also pretty big. It dangled about 8 inches above the floor when soft (and she was close to 5 feet high), and had to be at about as wide as a can of soda. Ever since you discovered her “secret”, she has been wearing slightly more revealing clothes to work every morning. Which is odd, since most of the other ponies in the building didn’t wear clothes. But as Rarity always has to be fabulous, she bucks the trend.

Today, she wore a light blue blouse with a purple tie, she had a white tail wrap, which was just above her black mini-skirt, if you could call it that. It was more like a black strip of fabric that covered her plothole and vagina, as well as some of her cutie mark. But it was more about what it didn’t cover. Her plump, black balls were just below the end of her thigh, and at this point in the day, at around 3 o’clock, she was feeling a bit exhausted on this warmer-than-average day. She didn’t mind sweating a bit, as she has been working on a new line for Hoity Toity, and was not to be interrupted by anyone who wasn’t you or Hoity himself.

You poke your head in the door, just about to take your break,

“Miss Rarity? Anything I can do for you at the moment?” you pipe up.

“Why yes, actually. I have this list for you with a small set of errands that need to be done before the end of the day”
Rarity usually went past the normal 9-5 of the normal workday, and usually worked whenever she felt like it. So you were basically always on call.

You look at the list, and there’s one item that sticks out to you today: “Massage Rarity’s ass.”

“Darling, as for the third item on that list, I’m going to need to bump that “appointment” to…now. I’m feeling oh so stressed, and need to take a small break so I can power through to finish these last few designs.”
This wasn’t an odd request, per se, but as you opened the door fully and walked in, you knew it was going to be a different kind of massage that day. You quickly ran to your office and grabbed your bottle of “massage oil”, and walked back in, bracing yourself. Her pink member was simply hanging there, and you could already see a wet spot on the carpet in her office right below it, and could just make out a small string of something.

“Well, my wonderful assistant, let’s started, shall we?”

You nod, and take off your dress shirt, tie, and slacks and neatly hang them up on an empty garment rack, which are everywhere in this office. Your undershirt and underwear are thrown onto the chaise lounge next to it. She is going to continue to work, as she likes to do during these “appointments”. You move behind her at her desk, where she is sketching something. You slowly grab the fastening on her skirt under her tail and slip if off, also going over to place it on a hanger next to your clothes.
You go to the door and place an “out to lunch” sign on her door, and lock it. You move behind the fashionista, and squirt a bit of the “oil” on your hands, and they each grab one cheek of her luxurious plot, and start to knead and work at it. Your thumbs making circles near the diamonds on each side.

“Excuse me, darling? While I know the list says “ass”, could we just move on to the important part. It feels wonderful, but it’s just teasing me at this point.”

“Yes, Miss Rarity.” You say, after swallowing and nodding slightly.

You grab a stool and sit down right in front of her plot, your eyes at the same level as your new target: her balls. Your first step is to cup them, one in each palm, as they get perfectly in your larger than normal hands. They feel heavy, like they’ve grown since the last time you’ve had an “appointment” of this kind. They feel damp, as there are beads of sweat all over her package. You can definitely smell it. You start to work your hands around the smooth skin of her ballsack. It’s definitely been moisturized, as you’re pretty sure she puts something all over her body to keep it that smooth. Your thumbs work in the same way as on her ass, thumbs rotating clockwise on each orb, switching to counter clockwise ever so often. You feel the skin stretching with every rotation, as you switch to a technique that looks like you are polishing them, as if they were the finest diamonds on the planet.

A splotch of pink catches your eye as you see her member start to work its way up towards her stomach, extending to the full 15 inches. You know you must be doing a good job, so you go to the next step. You scootch the stool closer, until your nose is almost touching them. You can almost feel the musk emanating off them, and you take a huge sniff in, taking in her essence, which is surprisingly feminine for such a masculine package. You breathe softly on it, and she shudders as your warm breath graces her testicles. You pucker your lips and kiss them, ever so gently. You move your lips around one globe, expanding and contracting your mouth in a wave of adoration, sucking the orb. You add tongue to it, lathering your saliva all over, tasting her salty sweat and the musk. This continues for some time, before switching to the other one. You start to see a constant drip of pre-cum hit the carpeting, so you know it’s a good job.

“Excuse me, wonderful assistant, we’re going to move on to the end now. I’m much too backed up.”

You oblige, and move the stool out of the way. She always wants to continue working, so you slink under her desk and move on to the piece de resistance. The pink shaft, now sticky from the precum, is ready. You look at it, the slit on the end staring back at you as her head begins to slightly flare. You grasp it with your hands, feeling the veins and the size, and move your head towards it.

You hold her dick on each side, moving your face towards the leaking slit, as it drips precum. Your tongue inches forward, preparing to taste her fluids. You stick your tongue into her urethra and start to lap up the precum. It's salty, but not too much. You stroke her shaft to try and coax more out of the leaking opening and you try and consume it as it comes out. You pull your tongue back and experience a little bit of resistance, you think nothing of it as you just want more of her pre. You dive back in, jamming your whole mouth into her dick as you continue to jack her off, not noticing that her flare has started to expand past the size of your head. Her slit was getting larger, too, as you were suddenly able to fit your whole mouth and jaw into her stallionhood. You should have seen the signs coming, but you took it to mean that you should try and go even deeper. You were practically eating out her urethra at this point. You tried to pull your head back to get some air, but you only felt a sharp resistance on your face. Like you were stuck and being sucked in.

You suddenly feel a lot warmer, and your head is suddenly all the way in her cock! You try to shout, but it only comes across as pleasure to Rarity, and she fails to notice that her genitalia is devouring you whole. Only when she hears a muffled Rrrty! does she look down to notice that her mare meat has closed around your neck like a sweater and is moving on to your shoulders. She looks down to see your hands pushing on her glans as you try and push yourself out of there.

"Oh, sorry, Darling! I just thought you were trying something new today. I'm afraid that once you're in, you have to go all the way. Don't worry, though, I'll have you out in a bit. Just as soon as I'm done with this design." She doesn't mention how you'll be exiting her carnivorous cock, but you're more concerned by the fact that her dick is currently eating you whole like a snake consumes a mouse.

The suction continues as your shoulders start to slide in, you can feel the pulsing of the flesh and your head is now getting warmer. You can smell the musk and you can practically taste her pre and her cum as it begins to soak into your skin and coats your body. Your arms begin to be pushed down as her dick seems to give a swallow like it had a throat. You feel the white unicorn shift and flex her dick so that it starts to point more upwards as she puts her front hooves on her desk, making sure she can start to use gravity as her feeding aid to get you in quickly and efficiently. Her soft, pink dick is now at full mast, harder and bigger than it's ever been before. The most her monstrous meat would "feed" on would be a mouse or two given by Fluttershy during Rarity's rut, so a full human was not in her "diet".

You continued to slip farther in, your arms pinned to the side as the last of your torso is consumed. And because all of this was so jarring, the erection you were sporting had gone away so your hips and dick were consumed as your legs were pushed together.

"Just a little bit more, dear. Then you'll be coming out."

You now had a little bit more time to think about what "coming out" meant, and you didn't think for much longer because you were 99% sure of what that meant. You continued to slide in as you felt your thighs and calves get sucked in. Your head and neck suddenly feel less constricted as you peek into the very anatomically incorrect ballsack. It feels like a balloon with a little ridge in the middle where there is normally a separation for the actual testicles. You think that this must be a side effect of having a magical penis that swallows things. The last cool feeling you feel are your bare feet as you wiggle them as you wave your metaphorical white flag, signaling to Rarity that you're almost done. If you weren't super scared right now, it would actually feel kinda nice to be in her shaft, like being in a sleeping bag surrounded by a huge comforter.

Your feet slide all the way in and her urethra goes back to its normal size and you are deposited in the leathery and slippery pouch of her genitals. You push out a couple times to signal to her that you're all the way in, and you feel yourself jostle around as she walks over to her fainting couch so she can rest.

She sits down on the couch like a certain minty-green unicorn she knows as her distended and filled sack hangs off of the edge, resting on the floor of her office. "Ooh, darling, just a bit of stimulation and you'll be ready to come out. You're going to look fantastic." You relax now that you're in her "pouch" and you feel like you're in a musky sauna. You do love the smell of her package, and this is like an essential-oil version of that. You were sitting ankle deep in a pool of her thick cum, sloshing around as she moved like you were in a kiddy pool. You were sweating as you felt a bit of motion as she started to rub her junk with her hooves and her magic. You were barely noticing how you were getting sleepier, sweatier, and transforming more into her semen as the time went on. First, all of your body hair started to come off, then you started to slump down more as the cum level began to rise like a creamy hot tub.

"You're just about done, dearie." Your body was making less and less of a distortion on the shape as you continued your transformation. Just as you were about to finish you thought to yell out to your captor.

"WAIT HOW ARE YOU GOING TO BRING ME BA-blub".

You didn't get to finish your sentence as the rest of your body merged with the rest of your body that had already been converted to her spunk. A few bubbles popped, very loudly, for that matter, and Rarity had noticed that as she was just about finished with her magazine that she had started as she was waiting for you to be done.

"Oh, he must be done! Don't worry, darling. You were wonderful. Let's get to getting you out."
