"Urgh, what's with this stuff," Mayor Mare said, shaking her hoof in front of her. She had come down into the sewers of Ponyville to check up on one of the local cleaners. She had been given reports of strange noises emanating from here at night.

Normally she would let the police handle it, but she felt this was easy enough to do on her own and didn't want to waste their time if it turned out to be a hoax.

Scrunching her face up, she shivered as she stepped forwards and felt the wet, gooey substance meld around her hoof. Placing more weight on it, she sank deeper; up to her knees.

Pulling her hoof out with quite a bit of effort, she trotted around to a section that didn't have such a large amount of goo and pressed on.

As she passed, the goo seemed to bubble before her very eyes and she picked up her pace and turned down one of the tunnels that connected to the entrance.

Pushing her glasses up, she came across a hard hat. It was covered in goo and had slightly melted. Picking the hat up, she felt her hoof tingle and dropped it, backing away slowly.

"Power Hose!" Mayor called out down the tunnel. She received to reply and turned to go back down.

A squelching sound made her pause, her ears swivelling around to find the source of the noise. Her ears stopped facing behind her and she turned around, squinting due to the low light.

"Power, is that you?" She asked, moving forwards slightly, not caring she had begun to step into goo.

She only noticed the goo around her knees was when she felt it hard to move her limbs. It started off slow at first, but gradually it became impossible to move her legs. It was as if the goo had turned to stone.

Mayor started to panic and try to pull away, 'urgh, let me go!" She screamed, fear taking hold. She waved her head around frantically looking for anything to help her out.

When she couldn't find anything, she started screaming at the top of her lungs, "Help, any pony!"

Hearing the squelching again, she froze. Her blood turned to ice as she saw the outline of a pony approach slowly.

She tried backing away and started shaking as she felt the goo tighten around her legs. "I shouldn't have come down here..." Mayor whimpered, tears dropping from her eyes and fading away as they touched the goo.

She could feel her legs tingling, it was the same cool feeling as if she had just had some chewing gum; cool and fresh. It made her feel full of energy.

Looking over at the silhouette, she called out, "what are you standing there for? Come and get me..."

The pony continued to stand, mocking her with its unused ability to move about.

Mayor Mare frowned, her fear gone. It was replaced with something much deadlier, acceptance. She had accepted her fate for some reason and was more than happy to just lay down and be covered by the warm, sensual, loving goo.

Feeling the goo loosen up around her she stepped out and knelt down in front of the pony. She felt lethargic and sluggish, as if she were running on autopilot.

The pony slid forwards into the path of light and could be seen. Its body was made of the same goo as before, the only difference was that this looked more animated, fluid even.

Mayor Mare felt uncomfortable and squirmed about. Her skin felt weird, wrong even.

The goo pony slid closer and lifted a hoof to Mayors cheek. The mayor stopped moving and stared into its eyes, feeling at peace.

The pony moved forwards, leaned down and kissed the mayor on the lips. It then gathered some of itself in its mouth and pushed it into hers.

Mayor swallowed it without a second though, determined to make it happy. The goo rewarded her with more of itself, forcing it down her throat.

This went on for hours, the mayor’s belly extending with each mouthful. She didn't know where her goo pony was getting her nectar, but she loved it.

The mayor loved it so much she started pleasuring herself while the pony fed her. She reached down and massaged her swollen button, gasping and taking in more of the delicious goo than usual.

The goo pony saw this and tilted its head. Pulling back it slid around the mayor and leaned down to take a look at her cunt.

The mayor spread her legs to give it a better look, secretly hoping it would feed this hole as well.

The goo poked at it, causing the mare to moan and buck her groin upwards. Seeing this reaction the goo placed her lips to the mayors slit and started to pump her full again.

The mayor's eyes rolled back in her head and she started to shake with pleasure. Too soon, the goo moved away and placed her lips on the mayor’s anus, filling that hole as well.

The mayor laid there, unable to move that lovely tingling washing through her remoulding her, lulling her to sleep.

She awoke to the sound of her stomach gurgling. Rising off the ground, she couldn't see her goo pony anywhere about but she could hear another mare succumbing to its pleasure and couldn't be happier.

Moving over to a drier area, she held he engorged belly as she moved, trying desperately to hold the contents of her ass in. The goo wouldn't be happy if she spilled it before it's time.

Sitting down, she burped and leaned down. Feeling something slide down her throat, she opened her mouth as far as it would go and vomited. Out slid a minute pony made of goo.

It looked up at the mayor and dragged itself over to her hoof and hugged it.

She felt more come up and vomited up several dozen more, each time her pride as a mother increased.

Once she felt all of the goo was out of her stomach, she got up, being careful with her babies climbing on her and spread her legs.

She began to force goo out of her ass. At least half a dozen were pushed out with no signs of stopping. "Come on!" She grunted, dropping a dozen more before she felt there was no more left inside her belly.

She reached down and spread her lips of her mare hood. Sighing from the touch, they were more sensitive than usual thanks to the goo.

She felt more babies crawl out of her cunt and drop on the floor with a wet splat. Looking down, she said they were fine and sighed; she didn't want her babies hurt, what kind of mother would she be then?

Only a handful of goo crawled out this time and it left her feeling empty. But as she looked around, she felt the pride of giving birth to so many babies that will show many, many mares what that goo showed her.

She yawned and stood up. The mayor walked over to the goo pile and waded in. She laid down inside it and slowly went to sleep. Not caring she was being warped into another goo pony.

Author's Note

This one was strange, but fun to write. I'm still not good with pacing, but what can you do, it's a clopfic about Mayor Mare getting inflated and giving birth to goo ponies...
