“You’ve been wanting this for a long time, huh?” 
You catch the lump in your throat as Pinkie slams that weighty ass back down, sucking your cock back inside the warmth of her marepussy and quickly rising back up again.
“Peek-a-boo!”
Sickened, wetted; a glistening sheen of pony cum that lets it glide back inside her soft, buttery mound with a harsh, wet smack.
“C’mon, Nonny! I’m not hearing any of that enthusiasm! You DO want this, right?”
“Mm-Hmm..”
“Then fuck the farts out of me!”

She slams those hips down even harder and faster, body jolting forwards with added momentum as she sucks you in and spits you out.
You feel that rhythmic tightening of her inner walls as she grabs your member inside her again.
“O-Ooh! Think I can feel something coming, Nonny! Is it chocolate cake, or is it laughing gas? Let’s find out!”
You hear her grunt to herself; throaty and strained, as she lets a few bursts of tight, wet gas tremble through that swollen ponut of hers.
You’re hit with that waft of stench; like month-old vanilla cake bathed in sulfur.

“F-Fuck...”
“Oh, you liked that? Then you’re gonna love the main course!”

You really don’t know how much longer you can last. The friction of her pussy-slamming is drawing you closer to that erupting orgasm, and the best part hasn’t even arrived yet.

“I haven’t pooped in - urgh - almost two days for you, Nonny. I wanted to give you the - gaahh! - biggest, thickest load I could!”

A few more airy farts shoot off. You can tell she’s getting close; they have that concentrated smell of pre-poop gas.

Your fault for telling her about no nut November, you suppose. Her offer to make you cum harder than you ever have before was too tempting to turn down.

Not only is she indulging your fantasies, she seems to be enjoying it herself.

“Oh, it’s com-ming! Just don’t go and ruin my surprise by blowing all that nice creamy icing inside me too early, okay?” 

You’re not in control anymore; not losing one ounce of stamina, Pinkie is still bouncing that ass up and down on your dick; making those hefty buttocks wobble and quake with every loud thumping impact. 

You stare at the winking of her asshole; sucking in and spasming outwards.

One last hissing fart proceeds that dark-brown turtle head; it stretches her hole and then stretches it some more, so wide you’re almost concerned it’s going to break.

“C-Can you see my chocolate fudge, Nonny? G-Gah! There’s so much...”

Her breath shudders as she eases that log out a little further, that wet crackle of mucus sliding along her taut anal walls as it curls out into one huge tube of pure pony shit.

It doesn’t look like regular pony shit, though... you inspect a little closer, and notice an array of bright, multicolored sprinkles embedded within.

“I added an extra little ingredient! I want my poopy to look so good you could almost eat it!”

All that churning, desperate cum saved up in your balls is begging to release, led on by the moistness of her slobbery, quivering snatch. 

The smell of tart, rich, earthy manure accompanies the swampy aroma of Pinkie’s pheromones.

You can practically see the shit steaming away as it catches the light over its uneven surface.

It extends a little further, and then gravity gets to work, cutting it away from her and making it fall down onto your belly with a dull thud.

“Oh, boy! That’s gotta be half a pound just on its own.”

The remainder of the log begins to press out of her with that same wet slick, a little faster as you hear her grunt and push.

She peers over her shoulder to watch this huge brown snake leaving her body.

“Wow-ee! Look at the - hnng - size of that thing!” 

Her sphincter cuts it off and it falls down over the previous log.

So heavy over your lower body you can feel it weighing down on you, along with imbuing you with that intense warmth leftover from her inner body.

The sheer amount of feces produced by this pony so far is absolutely astounding; you’re not even sure how so much can fit inside her, and certainly not sure how she can maintain her bubbly, energetic demeanour with all that waste stored up and begging to be released. 

There’s still even more, though; crowning and developing into another bulky turd that rises up above you, almost blocking out the light, and falls down onto the steaming pile of excrement already covering your stomach and chest.

“A-Agh!”
“Oh, I bet you’re super duper close now, Nonny, huh? I could drown you in a little more Pinkie poop, but I guess I’ll let you finish.” 

She lets your dick slide out of her and jumps up, turning herself around and laying down flat over your legs so she’s right below your cock.

“P.U! That’s no chocolate!” 

She giggles, lowering her head to suckle on your balls; her tongue works to massage them softly, stirring up the cum that’s building inside.

So desperate it hurts.

Her tongue trails upwards, reaching the base of your shaft and then, wide and enveloping, works along the underside and pushing it up against your stomach, aimed perfectly towards the shit-heap she’s just produced.

“C’maaahnn! Creme toppin, creme toopin!” She speaks with her mouth agape, hot, sticky salvia dribbling around your dick as you feel the head start to push softly into that mass of shit pinning you down.

With a potent fizzing sensation spreading through your privates, she brings you to that intense, euphoric orgasm.

Your mind goes white and numb as you let out an uncontrollable groan and spray your pent-up over Pinkie’s soft-serve brownie cake mix.

It just keeps coming and coming, even after you’ve drizzled ropes and strands across the surface of the shit-heap.

Pinkie sucks it into her mouth and you feel yourself explode the last few rounds down her throat.

The most intense afterglow you’ve ever experienced; almost dizzying.

She tilts her head back, gargles loudly with your cum, and gulps it down.

“Mmh! Hey, you’re right! It tastes even better when it’s been brewing for half a month!”

“Mmh.”

“Nonny? Oh, I didn’t fry your brain, did I?” 

“Ughhnn..”

“C’mon, silly! You’re gonna need the stamina for round two!”

“Wh-Huh!? Round two?”

“Well, yeah! You thought that was all the poop I had? C’mon! That’s, like, not even a quarter!” 

“It... isn’t?”

She gives you a wink and hops back up onto you, whether you’re ready or not...
