Once upon a time, there was a pink party-planning pony. She was bringing a big red stallion to the bakery she worked at after hours for a very special blind taste test of a pie he had never had before.
"I know it's unusual to wear a blindfold to taste a pie," said Pinkie as she guided Big Mac to the back of the bakery, "but they wouldn't call it a blind taste test if you could see, could you?"
He shrugged.
"We're almost there," she said as she took him through a fairly narrow door, "You can't smell anything, can you?"
"Ah-nope," he replied amiably.
"Good," she said. "We're almost ready to begin."
Big Mac wondered if they were alone since he could hear another being breathing softly in the room with them, but he didn't want to say anything about it if he didn't have to. Perhaps another pony was with them?
Pinkie grabbed him by the jowls and slowly pulled him forward until he could smell some kind of apple pie filling. Possibly even Zap Apple pie. Taking an experimental lick, he realized it was in fact Zap Apple Pie Filling (TM applied for).
However, there was a second somewhat tart and salty taste just under it. It also had a really strange texture against his tongue. He gave another long lick to be sure, but then he could have sworn something moved. Then he reared his head to lick his lips.
"So what'cha think?" asked Pinkie eagerly.
"Mmm... I know that there Zap Apple Pie Filling," he replied, "but ah don't recognize that there crust or whatever that is underneath."
"Didya like it?"
"Oh, it's good an all..." he mused evenly, "but it just ain't as good as Granny Smith's."
Pinkie grabbed his jowls and pulled him back into it. "Just one more taste," she begged, "Puh-lease?!"
He reckoned it wouldn't hurt so he gave the biggest lick yet. This time, he was sure it was moving as he licked.
"What all is goin on here, Pinkie?" he asked as he licked his lips again. The tangy taste under the pie filling was beginning to fascinate the large red Earth pony.
Things suddenly became clear when Pinkie pulled off the blindfold. In front of him was a cot, and hogtied down to the cot was a very blushing Marble Pie. She was tied on her back so her tail wasn't in the way of her crotch. That was tied down under the cot loosely. He could see her hind legs were tied so she just couldn't close them, and that the Zap Apple Pie Filling was smeared all over her loins and crotch. He was most likely licking right up and down her pony pussy.
Pinkie popped the ball gag out of her sister's mouth, leaving her panting as Pinkie said, "See sis? I told you I could get Big Mac to try oral sex with you!"
"A-what-now?"
"That's the surprise!" announced Pinkie, "The Pie you're tasting is MARBLE PIE!!"
"Uh... okay," he said slightly confused.
"Uh-huh," added Marble Pie quietly.
"You have to admit you've never tasted Marble Pie before!" blurt out Pinkie.
"Uh... I reckon not," he replied as he took a step back.
Pinkie got behind him to stop him from backing up as she pleaded, "C'mon Big Mac. You can't leave my sis hanging. Get in there and chow down already."
Marble blushed hotly.
He stepped up once more and began hotly licking her pussy from bottom to top. She squirmed with each lick and lap he took of her.
In the meantime, Pinkie slipped up next to his ear and whispered, "Marble's not in season right now, so she begged me to ask you to... you know... mount her and stuff."
"Huh?!" he asked as he paused licking.
Marble gestured with her head, so Pinkie came over and she whispered something into Pinkie's ear.
"Oh," said Pinkie, "She wants you to keep licking her til she cums and then mount her."
By now, Big Mac was blushing as much as Marble, but he nodded his head in agreement. He leaned in as he pressed his tongue ever deeper into Marble's birth canal. Soon, his lips sealed her honey pot opening leaving most of her pussy covered. She quivered and shivered as he pressed his tongue ever deeper.
"And here my little sister thought that you wouldn't think she was cute enough," gloated Pinkie.
Marble panted harder even though she was hardly making more sound than a decent whisper. She laid her head back as she panted open-mouthed.
"I told her you were good with your tongue," she whispered into his ear.
While she hardly made a sound, both Pinkie and Big Mac could tell when she orgasmed by the juices that leaked out from his mouth. She came rather messily inside his mouth. Pinkie could tell by the way he was swallowing her juices.
Pinkie looked under his stomach ahead of his stifle and noticed that his cock was almost fully erect already. She just leaned closer and licked his big ole shaft from the base to the tip a few times to make sure it was nice and slick. He moaned into Marble's pussy as Pinkie licked him firmly.
Then Pinkie pushed him back making his mouth release from her pussy with an audible popping sound. By now, all the pie filling was licked off her quivering femslit to be replaced with her own flowing juices.
"Now Marble," she said, "I just want to be absolutely sure that you still want Big Macintosh to mount you. If you have the slightest doubt, we'll stop it right here and now."
Marble nodded yes eagerly.
"And do you mind... would you like to... mount my sister?" asked Pinkie hopefully.
"Aaa-yup!"
She helped him rear up so he could place his hooves on either side of Marble's hips. That way, he could steady himself as he drove his stallion-meat into her sister's pussy. His weight was on the cot instead of Marble Pie. He slowly slipped his cock into her as if she were fragile and his cock might split her up the middle with even the slightest mistake on his part. She grimaced as his dick slipped into her love canal inch by inch.
"I think you've been officially deflowered," whispered Pinkie very quietly to Marble.
Minutes passed, and then he paused to back up until he was almost out of her again.
Pinkie moved up to her sister's head and stroked her cheek as she asked, "Want him to continue? If it hurts in the least, I promise we'll stop this whole thing right now."
Marble nodded yes, so now Big Mac began slipping his cock into her again slightly faster. She closed her eyes tight as he entered her again, but Pinkie figured she wanted him to keep going. Once he was almost all the way in, he started humping her slowly and gently. Each stroke was just a tiny bit longer and a tiny bit faster than the one before.
"I don't know why, but I feel so proud of my little sister right now," sniffed Pinkie.
Marble began rolling her head from side to side as her excitement grew like crazy. Big Mac's panting meant that he was coming closer to the moment he blew his wad as well. Once his cock was fully erect, the head of his cock would spread out making it impossible to pull out until he was done pumping his seed into the gray mare.
"Oh yeah sugar-cube," he moaned, "I'm'ah comin around the mountain!"
Pinkie figured that was some kind of code for "I'm blowing my wad, sugar-cube!" She could tell by the way his stomach quivered that he was in fact blowing his was right up into Marble's womb.
When he was done, he simply collapsed on top of Marble as he panted. It would still be another minute or two before he could pull out.
"Did you have fun there sis?!" asked Pinkie.
"Uh-huh," she said softly.
"And you think my sis is pretty?" she asked Big Mac.
"A-yup!"
She turned around to asked, "And did you two have fun watching us, Limestone? Maud?"
Big Mac turned his head to see Limestone's head vanish around the corner, but Maud was just plain staring.
"Yes," replied Maud, "I am moved to recite a poem about this."
"Let's hear it!" proclaimed Pinkie.
Marble Pie like rock,
Big Mack stick her with his cock,
His dick hard like rock.
"That's wonderful!" proclaimed Pinkie.
Big Mac and Marble were too busy looking into each other's eyes to comment. Then he gave her a full kiss on her lips.
