Piece Of Cake Ch. 1 [Transformation, Fat, Trap?]

The art of potion making had always intrigued you, since you first arrived in Equestia.
In fact, just a few months ago you had taken up an apprenticeship with Zecora. She taught you the ins and outs of potions and you had built up your own lab, not big but large enough for the basics.
You'd never admit it to anyone else but you had acquired all of the necessary components of a transformation potion. You stashed each component just out of reach of each other, in case some pony were to wander in, and find them. Ponies got a bit touchy with those who deal with powerful magics on their own time.
All you had to do was keep it in hand for the landlords, the Cakes. Pinkie, too. She was an observant one, not the prying type but she'd pick you out if she noticed you were doing anything too hot up there.
The Cakes were fine with a little convincing, as long as you kept it easy they would let you practice up in your room.
And you did. But also a little fun... side project.
You had massed enough to produce a single dose of the potion and intended to... Well transform your dick.
All for totally scientific reasons of course.
Yep.

Buuut...
The thought of a 12 inch gargantuan tube, spilling out of your own sheath, pulsing flare and thick medial ring excited you to no end.
Wouldn't be too hard to hide such a transformation, either.
Granted you could keep your inopportune erections from pitching a massive tent.
But then, what fun would that be, without a little risk involved?

The potion would be entirely localized, you made sure, double checking as much literature on the subject as possible, Twilight's library was a godsend.
It took nearly three weeks to brew and even involved the use of a stallion's semen to localize the change.
You weren't too happy to get some fresh from the source but lucky for you Ponyville's got some weird back alley markets.
A little disgusting, though.

But more to the point, it's nearly finished.
Careful repositioning of equipment and timing was needed but three weeks come and gone, you nearly had it.

Zecora herself said that failed potions were little more than benign, if not disgusting, mixtures. If it didn't pan out, the worst you could really expect was chugging a foul tasting, stallion semen, concoction.
Hopefully worth the end result.

But now it really was time to bring it off heat, that it had settled into its final state.
You removed your smock, drying your hands, dehydrated and shriveled from finishing washing the large amount of cooking utensils and dishes the Cakes roll through on a regular basis.
You took your leave, climbing the steps to your room, waving off to Mr. Cake behind the counter.
Mrs. Cake herself waddles down the stairs past you, her belly brushing the steps as she descended.
"Anon, sweetie, after your break could you help with today's batch of cookies?"
"Sure thing, Mrs."
You nod, taking a glance back as she passes, her ass wobbling with each unsteady step, huffing a little with her movement.
She was truly a colossal mare. I mean, you hadn't expected to find eccentric tastes the same as you did back on Earth but if anything was certain, Mr. Cake was one hell of chubby chaser. Even from your upstairs room you could hear the two going at it before the day was over.
Not that you weren't interested, too. Always used to find fat a little appealing...
Just good to know there's still hope of a sex life for you, here.

Creaking open the door you find your small bed, a few dressers lined with equipment and a bookshelf, piled high with glass containers and old books on Zebra alchemy.
The sheets must've been replaced.
You take a glance over your equipment noting that nothing seems to have been touched, sighing with relief.
You'll thank Mrs. Cake on your trip back down, you're a little surprised how nimble she is, for her size.
That mare's belly is large enough to nearly drag over the ground. And she's only gotten bigger, over the time you've known her.

You switch off the magical heating element, the glass column dripping above winds down and you remove the bubbling flask to cool.
Gently lifting the precious iridescent blue -Huh, maybe this is the change in color the book specified, when ready- liquid and placed it in a small container of water to speed the cooling process.
You take a lie down on the bed and a glance at the door before rising up, clicking the lock in place and walking back to the potion.

-This is probably the most disgusting substance you hope you will never have to consume again.-
You think as the smell meets your nose.

You steel yourself, purse your lips, and tip back the still warm substance.
Seconds later the taste rears its head and you come close to heaving, pushing it down in two thick gulps.
You wince and drop the flask onto the table, gagging, before downing the bucket of cooling liquid in deep swigs.

As the nausea subsides, you fall back onto the bed, laughing a little and gasping.
You feel a heat in your pants and work quickly to unbutton them as the warmth spreads.
Your genitals feel almost hot as you pull down your underwear, to confirm its workings.
Your penis darkens in color, simultaneously becoming erect, as it's elongates.
You breathing becomes unsteady, excitement takes hold of you as your work unfolds, medial ring protruding.
New veins pop delicately into its surface as you grip it with your hand, your fingers feeling up and down.
You shed your clothing as the transformation reaches its apex, heat and pleasurable sensations bombard you as you struggle not to giggle at the euphoria washing over you. It springs up, towering above your chest, truly enourmous dark black stallion cock. You lean in just as the flare fully forms and begins to pulsate, grabbing hold of your dick you find yourself able to direct it to your lips and into your awaiting mouth. Thick saliva coats the end as you can force it to the back of your throat and push, yet further.
You stop suddenly as the sensation in your dick falls away and a new one takes hold of your testicles.
Propping yourself up, you lean in to discover them expanding and darkening in color. They become vastly heavier and much larger. You take hold of each of them, pressing and massaging with your fingers as gently as you can.
Your old ones give way to a massive set of jet black and glossy stallion balls.
Your heart is racing as the change continues downward, lifting your heavy new set to reveal your taint darkening and you anus distending into a thick ponut.

The changes seem to progress a little further than you intended but nothing is quite out of place, per say.
Well, that is... Until the odd warmth began to grow in your belly.
You gasp a little and clasp your gut with both hands, your eyes confirming your fear.
It begins to swell.
You panic, warmth spreading to every joint and surface of your body.
You watch in horror as belly sprouts light blue fur just as it begins to tower over your throbbing cock. You recoil again, your thighs thickening rapidly.
You grasp the swelling flesh with your hands before noting their decreased sensitivity.
bringing them to your face, you examine your fingers, as they mesh together.
"Fuck..." You sputter as the warmth overtakes your jaw and throat, elongating it and lightening your voice.
A quick glance to the heating element reveals a few strand of blue hair, locked in between the switch.

...

-Okay Brain, Chance that Mrs. Cake accidentally fucked with the heating element and got her own sample mixed in while helping make your bed?-
~Almost surely.~
-Chances that potion wasn't botched and we're not transforming into a fat blue pony for the rest of our natural lives?-
~Near to none.~
-We're properly fucked. Aren't we.-
~On a scale of 1-10? 11.~

...

You grunt in a higher pitched tone than usual, your body contorts as you lay in bed.
Joints crack, bones shift, all sorts of horrible sensations of discomfort wash over you. The Blue fur spreads over you. Hair lengthens as it shifts a deep red in color. A tail makes its way out of the base of your shrinking spine.
But this belly... You move to sit up, your colossal gut wobbles before you slip right back onto your back.
Oh god. You won't be able to move. You're fucking turning into your milf landlord.
Your body is stiffening up as it transforms, you can barely move.
Oh fuck.
Oh shit.
Your feet dangle off to the sides, they're already some kind of half hoof, half foot amalgamation.
The blue fur seems to encapsulate your body, every inch of it padded in warm, soft fur. You ass swelling has raised your rear up, sightly. The added weight is straining your old bed, you need to get off of this thing, now.
With your stiff, transforming joints, you shift your body's weight left and right, swinging it until your belly falls far enough, slipping over the edge of the bed and carrying you with it.
You slump onto the floor with a large thud, your unfamiliar body jiggling wildly in the process, floor boards creaking.
"No no no... This can't be real..." A voice much different from your own is heard to speak.
You strain to lift your body onto all fours.
Fingers aren't there; toes none the better... It's just hard around the edges and soft in the middle.
They're hooves.
You can't stand anymore.
Your heavy gut, ass, and newly formed quadrupedal stance hold you firmly to the ground on all four hooves.
Your belly barely meets the ground below you.
Your joints crack their last, legs evening out in length. Your neck cracks heavily before enabling it's newly formed flexibility, even through the thick rolls of fat encapsulating it.
You utilize your new flexibility to take a look back.
A new poofy red tail juts out between the two massive wobbling cheeks of your ass, each adorned with a cutie mark.
Her cutie mark.
Three cupcakes drawn over the surface of each round cheek.
A shift of your thighs reveals the thick cock, still throbbing powerfully behind the mass of your body.
You must look like a mare but you sport a fully sized set of stallion equipment...
You can't see it now...
You can't even reach it.
Its in between your huge ass, behind your belly.
You lean in and rest the weight on your impressively large stomach, both hooves clawing at your sides.
You won't be able to reach it...


A knock at the door sounds out...
"Anon? You okay in there? I heard a thump."
