The sound of a large creaking door broke Pinkie out of her sleep. Last thing she remembered was eating cupcakes at Sugarcube Corner. She lifted her legs to try and move only to realize she was shackled down. The blindfold on her head didn't help her out much either.

"What? Whats going on?!"

Pinkie struggled against the shackles until she realized she wasn't alone. The soft clip-clop of horse shoes echoed behind her.

"Hello? Can you help me?"

The other pony said nothing. Instead, the steps became louder and louder until Pinkie felt them right behind her.

"Help! Somepony help me!" Pinkie pleaded.

"Shhhh, it's alright girl."

The southern twang in the visitors voice instantly gave away her identity. "Applejack? What's going on?"

Applejack didn't answer. Instead, Pinkie felt a warm breath flow across her sex. Pinkie tensed, but soon eased herself up.

"Applejack, I want out!"

Instead of words, applejack replied by placing a hoof on Pinkie's flank.

"What the hay are you doi-"

Pinkie felt a nip at her neck, very gentle though. "Don't ya worry. If you let me, I'll show you a good time."

Pinkie felt the cowpony take her one of her hooves and pulled it over, placing it on something warm and large. The pink pony probed it carefully trying to get a good idea of what it was.

"What is that? It feels weird..."

"That, my little cinnamon bun, is me. Just wait till you get the icing!"

It finally hit Pinkie just what she was touching. She moved her hoof back exploratory only to discover another appendage. This one was round and pulsing. If she had to guess, each side of it had to be the size of a basketball each!

"A-Applejack?!"

The stetson-clad pony laughed darkly. "That's right! All of that is just for you. Now you just sit right there and let ole AJ take care of you."

Pinkie's knees nearly buckled as the highly endowed mare mounted her rear. She didn't say it aloud, but she wanted this. She wanted to feel Applejack's massive cock plunge into her and hammer her. She wanted to feel all of the cowpony's cum bloat her womb. It came as no surprise when she felt her marehood winking involuntarily. This was it, her last chance to stop this.

"Applejack, please..."

Applejack leaned in close to Pinkie's ear. "Please what, Sugarcube?"

Pinkie clenched her teeth as she felt the tip of he cowpony's member poke her sopping wet vagina.

"Please give it to me!"

"Now you've come to your senses. Here we go."

Pinkie clenched in anticipation. As soon as the giant penis started ploughing into her, she squealed out. She had never felt any thing quite like it. She immediately had visions of a bulldozer trying to drive through a tiny alleyway. Pinkie's mouth hung open as Applejack buried more and more of her length inside the party pony. Another loud scream cut through the air abruptly as she struggled to take the entire cock. Applejack slowed her insertion, letting her get used to the tremendous size. Pinkie gasped and panted for a little bit, trying to get herself to loosen up more for the intrusive cock.

"Yer boring me, Sugar. I'm not even halfway in yet."

Pinkie's eyes lit upon hearing this, and her canal clenched involuntarily. She gasped as Applejack pushed more of the burgeoning length inside her.

It hurt, by the solar god's mane, did it hurt, but it also felt good. She felt the dull pleasure throbbing in the folds of her marehood.

"Not much longer now."

Pinkie could barely register what AJ was saying through the fog in her mind. All she knew was that her poor pussy was being stretched like the balloons she would mercilessly inflate until they exploded. .

"Ahhhhhh!" a new feeling of pressure hit the party pony as Applejack's huge throbbing meat hit a barrier.

"You know what that is, Sugarcube?" Applejack asked. Pinkie shook her head between gasps.

"That's your cervix. It's the last barrier between my semen and your womb. I'm gonna break through and pump all this icing into your tiny womb until it looks like one of them balloons you like blowin up so much."

Applejack thrusted and the barrier pushed aside. Pinkie squealed again in reaction.

Finally buried to the hilt, Applejack pulled back a little bit. "Ok, Sugar, here we go."

Pinkie threw her head back as the cowpony began thrusting rhythmically sawing in and out of Pinkie's poor abused pussy. Pinkie could not care less at the moment however. She felt every vein, every bulge, every throb in the massive member penetrating her. Her canal's muscles randomly clenched milking the turgid cock.. The pain in her pussy gave way for a rising pleasure, a sense of pressure. She felt like the town's dam, holding back endless amounts of water. She felt Applejack's thrusting get more frantic.

"A-Applejack! If you cum inside, I'll get pregnant!" Pinkie warned.

"Damn right you will! Yer gonna carry my foal in that there belly!"

Hearing that nearly pushed Pinkie over the edge. Her knees buckled and she collapsed to the ground in mindless pleasure. That didn't stop Applejack though. She just started pounding Pinkie even harder.

"Applejack! I'm going to-"

"Me too!"

Pinkie threw her head back as she came. Her pussy clenched and spasmed around the giant cock inside her. She barely had a moment's reprieve before Applejack bellowed. Impossibly, she felt the giant cock throb and grow stretching her wider. During their reckless sex, Pinkie's blindfold had shifted, allowing her to see partially see again. She barely managed to turn her head to look at Applejack. Though she didn't have a good angle, she saw enough of the bloated sack hanging off of the cowpony's crotch to see it churn and pump it's payload into Applejack's twitching member.

With one last forceful thrust, Applejack came. Pinkie felt the boiling seed gush into her. Burst after burst exploded inside her tiny womb stretching it. Suddenly she felt it. Placing her hoof on her belly, she felt the skin start to stretch. She felt the gouts of cum pump into her, bloating her once slightly chubby barrel. In her mind, she pictured the eclairs she made. She pictured them plumping up and filling when she squeezed the icing into them. She was stuck with that mental image of being Applejack's pastry, being filled beyond capacity with gallons of her icing. Each blast of cum was punctuated with an animalistic thrust.

"We're not done, unf, until you get it all!"

Pinkie felt her belly pushing her off the floor, blimping further with each spray of cum. She wrapped her hooves around her stretching mid-section, enjoying the feeling of being pumped way too much. More and more her belly billowed as it went past the size of a beanbag. Applejack clung to her backside like a tick, instead of sucking though, she was offering impossible amounts of virile semen.

"Woa, wha, woah!"

Pinkie felt her center of gravity shift as Applejack thrusted too hard to the left. Pinkie, stranded atop her belly, rolled over and hit her side on the ground. With one last buck, Applejack pushed hard exploding one last burst of her potent cream inside of the pink mare. The prodigious belly quaked and jiggled as it came to a rest and both ponies breathed and panted heavily.

Pinkie, now sporting a belly five feet in diameter packed with cum beyond the limits of any normal pony, slid her hooves out of the shackles that "bound her" and pulled the blindfold completely off.

"That... that was amazing, Applejack," she cooed. "Thanks for setting it up for me."

"You were pretty good yourself sugar." With her cock still buried inside of her lover, Applejack leaned forward and kissed Pinkie deeply. "I don't rightly enjoy pretending ta do something so wrong against yer will, but for you I'll do it.

"Thanks Applejack. How long are you stuck with your..."

"Zecora said it should just be a couple hours or so. One things fer sure, I can't go complaining that it didn't work!" Applejack laughed.

"I wonder if the thing Twilight said she did worked."

Applejack's ears raised. "Wazzat now?"

Pinkie smiled. "Oh nothing. I just told Twilight about how we've been trying to get pregnant, so she said something about increasing my fertility, whatever that means, so she did some sort of spell that she said would increase the number of eggs I release."

"Wha, WHAT?!"

"Yeah, something like ten times the usual," Pinkie said nonchalantly.

Applejack's eyes widened when she realized what that meant. Ballooned with cum the way Pinkie was, it was doubtful those eggs weren't swimming in there.

"You have no idea what any of that meant, do ya Pinkie?"

"Nope!" the pink mare replied enthusiastically.

Applejack smiled and placed a gentle hoof on Pinkie's giant belly. How ever many they would have, the foals would not want for love in their family.

Author's Note

Just to clarify in case you didn't get it, It wasn't non-consensual. the whole being shackled and blindfolded at the beginning was just roleplay.
