A knock at the door is heard.
The woman looks up from her book before a voice on the other end speaks.
"Anonymous? Are you in?"
That sounds oddly like... Celestia. Here? Now? Hopefully not something involving you. She sighs before removing herself from the seat and making way to the door. A clack of the lock and the door squeaks open revealing the Princess of Equestria standing at the doorstep, her multicolor flowing mane, tall and slender stature, colossal gut that jiggles as she makes an attempt to climb the small porch steps. The princess releases a hearty belch, a powerful gurgle resounding from her insides as she ascends, leaving the poor human wide-eyed at her obscene state.
"Anon, may I come in to rest a moment?"
It takes the woman a moment to respond, her eyes transfixed on the princess.
"Yes!"
She cocks her eyebrow as the princess makes a scene of her wobbly entrance before taking a heavy sit down on the old worn out seat she had just gotten up from. Now that she thinks about it... Where was the guard escort?
She's accompanied everywhere she goes by a small group, why aren't they here, now?
And more to the point, why the belly?
"Princess, what happened to you? You're..."
"Some minor hiccups of diplomacy-" Another loud burp makes it's way up, interrupting her speech.
"Diamond dogs are a proud bunch. Their leader, especially, boastful. Very gluttonous, too. Perhaps the details later, for now I need some help."
She gulps a little at the sight of her turgid gut, hooves sinking in gradually, kneading it gently.
"You work for Aloe and Lotus, the twins who run the spa in town, do you not?"
She nods, starting to see where this is going.
"I would like to request your services, I hear you can work wonders. I would be very appreciative if you help the digestion along."
"Just... Rub?"
"Quite firmly, yes."
She comes close, placing both hands atop the mass of gurgling food in her digestive tract, and begins to press both hands deeply into her flesh, rubbing circles with her palms. The bubbling and noise of her gut grows as time passes, burps are brought out, the princess blushing heavily as one firm squish of the fingertips evokes a gaseous release from her rear end.
"You can't just use magic for this, right?" The human asks.
"Perhaps I was interested in-" -urp- "In a more, intimate, touch." She replies.
The large orb that is her stomach gradually release it's tight grip, the contents softening up and becoming pliable in her hands, yet still very solid at it's core; more work remains. The princess makes motions with her hooves, directing her touch to where she needs it. Occasionally a soft coo will escape her lips as she reaches a most desperately needed spot, massaging the kinks out.
"I think we're ready for the next step."
What? Next?
Anonymous removes her hands as Celestia's horn shines a bright gold.
"Wh- What are you doing?"
"Be calm Anonymous, I promise it will feel good."
She winces, a strange sensation making itself apparent from her groin.
She buckles over clasping her nethers as they bulge hugely. She reaches for the waistband of her pants, a large speckle painted stallions's cock popping out from over the edge and well into Celestia's view.
She tries to shield her newly developed length as it presents itself in front of the leader of Equestria. Strange but pleasant sensations make themselves known, a hardness and throbbing that seem to cloud her thoughts.
"Are you going to finish what you started?"
She's sweating beads as the princess licks her lips, gripping her stomach and aims her navel upward.
"I think you can figure out how to use it..."
Holy shit! It's got to be longer than a foot. Probably 16 inches.
"Celestia, it's... just- I-"
"Nonsense, this is a regular stallion's size. You have plenty to work with. Perhaps you may not be able to quite satisfy my needs, just yet."
Celestia's magical aura pulls her pants down as two testicles begin to form and expand, they swell stopping only as they reach a fairly sizeable grapefruit, each.
She reaches down to grip one in her hand, the hefty, seed filled, orbs spreading her legs apart.
A light squeeze generates discomfort before a pang of pleasure as a large volume of liquid squirts out of her tip and onto Celestia's belly. The human's other hand begins to work the shaft, feeling up and down, taking special care to explore the thick medial ring she has been given.
She looks up lustfully to Celestia before slowly plunging the tip of her cock into the princesses' navel. She grips a fold of her tight stomach, squishing the rolls of flab as she penetrates deeper into the impossible depth of her belly.
Her medial ring passes as the sensations of soft flesh elicit pulses of lubricating pre that allow her to glide easily in.
She finally hilts, her massive testicles, heavy and full contact.
Celestia gasps as her wings extend, closing her eyes and basking in the feeling of the human drawing back out of her well soaked fuck hole. She presses back in, faster this time, her testicles slapping against wet flesh.
The human buckles onto her belly for support, gripping the princesses' hooves as she makes a pace out of slamming the unwieldy object in and out of her, the human could swear she heard the sensitive orbs of seed slosh as her pounding picked up pace. Perhaps it was just Celestia's gut...
Quickly she worked up her way to orgasm, a great tension building in her loins. As it reached it's peak it snapped, her overly full balls pulsing in unison with her length as it shot thick and sticky ropes of semen inside of her navel.
She continued to pound, to the princesses' delight as her navel was quickly filled to capacity, leaking seed around her hips, coating the both of them in wondrous amounts of sticky liquid.
The human slowly winds down, resting on top of the alicorn's great belly, basking in the sensation of the after orgasm, still inside of the princess as her erection fades, testicles still large and heavy between her legs.
"You may serve better than I expected. How would you like a job at the palace?"
"And... And if I refuse?"
"You may. But we have ~no~ way of reversing such physiological changes here and now. We can go there, now, if you'd like."
She looks down, finding her new organ retreating into it's sheath, testicles forcing her legs apart a burdensome amount as each touch of them manages to elicit a healthy amount of pre from her flaccid length,pooling out from her sheath and coating the floor under her in unending flow.
She looks back up and groans as Celestia licks her lips, a splotch of seed propelled out of her navel, after a squish of her stomach.
