Big Macintosh's Lesson

WARNING: Nasty details. BigMacintosh X TwilightSparkle X Applejack

...

Big Macintosh was a large studly stallion, and he was in an awkward position. He was over a hay bale so his back legs were spread fairly wide, and his hot throbbing cock was hanging off the end pressing itself into the hay. The forelegs were bound behind his back at the pasterns, and his legs were tied tightly on either side of the hay bale. His two foot long plus erection was throbbing and purple because Applejack put a leather bracelet around his shaft like a belt, constricting the shaft tighter than he had ever felt before. Between the bracelet and his balls was his great knot of jism, trapped and unable to proceed towards the opening at the end of his cock. Applejack fondled his balls as he strained to get his wad out, quickly causing his balls to turn as violet as his erection. His balls were so tight, they felt like solid rubber under the tender manipulations of Applejack's hooves. The force holding his cum back was painful, but not the kind of pain he wasn't expecting to suffer. At the other end, his tongue was lapping and probing Twilight's femslit which she had shoved right against his snout. His large, slobbering tongue gave Twilight great pleasure as he worked his spit between her nether lips and even into her quivering birth canal. She couldn't be much blamed, as he had his eyes closed at the time.

Applejack reached into the box with one hoof while fondling his hard balls with the other. She was definitely feeling around the box like she was looking for something. It didn't appear that she was having to much luck finding it as she dug around in the box, shifting the items around within. "Now whar did I put that..." she mumbled, "No... No... That ain't it... Ah, there y'all is."

She pulled out something that caught Twilight's attention. It was short and wide, and sort of shaped like a door knob with a slight point at the end. Twilight wasn't sure, but there appeared to be a twist knob at the end with little numbers on it ranging from 0 (off) to 10.

"My goodness," said Twilight, "What the heck is that?"

"Oh, this here's a voob... veeb... vube..." she sighed, "Oh you tell her, slave."

He opened one eye as she waved the device in his face, making him stop licking Twilight's snatch for several seconds.

"That thar is a vibrating-type butt plug," he said helpfully.

"Butt plug?" asked Twilight as she leaned closer to look.

"Eyup," said Applejack, "Once I stick this here thing in his there poop hole, he won't be able ta crap til I takes it out again. It also vee-bra-tes in his poop chute, an Big Brother sez that all is another turn on." She turned it on high, making her hoof visibly shake as she held it. When she lined it up with his sphincter, Twilight said, "You're gonna shove that in dry?"

"Oh yeah," she replied, "if'n I lubed it up first, he might just push it right outta his butt when he's got a load backed up in him. Kinda defeats the purpose."

"Oh..." sighed Twilight as Applejack shoved the vibrating butt plug hard into his dry butt-hole, making the big red stallion moan loudly against Twilight's slobbering femslit. She wiggled the plug around to make sure it was tight, making Big Mac moan and squirm even more.

"Hey slave," moaned Twilight, "I didn't give you permission to stop licking me. Now get that hot long tongue back in my vagina, and I mean now."

Big Macintosh obliged by shoving his tongue back into her quivering hot slobbering vaginal canal. Twilight put her hooves on his head just behind his ears, pressing his muzzle tighter into her femslit.

"Oh yeah," she moaned, "Your tongue is a gift to mares."

Applejack shifted one hoof from fondling his balls to fondling the head of his cock. She pulled her hoof back and sniffed it, and realized that in spite of how tight his shaft was constricted, some of his cum was still leaking through. It was confirmed both by her eyes, and her tongue when she lapped at her own hoof.

Twilight moaned louder as he all but screwed her with his tongue. She found it hard to believe just how far his tongue was penetrating her birth canal. It was like a stallion cock, but more flexible and very much wetter. He pressed his tongue against her g-spot as his front teeth rubbed against her hot and throbbing clit. She grabbed his ears and pulled as she climaxed loudly, her juices freely flowing over his tongue, and both in and around his mouth.

Applejack reached into her box a pulled out a super-horse-size heavy-duty condom out of it along with a ball of string and a tube. Taking the tube in one hoof and the condom in the other, she partly unrolled it before she uncapped the tube and squirted a bunch of white pasty fluid into it. She continued to unroll the condom until with was nearly a foot and a half long, rubbing the thick fluid along its length as she did so.

"What's that?" asked Twilight.

"Oh this here is a condom," she replied as she started sliding it over his hot throbbing cock.

"And the stuff you put in it?"

"Its some kind of wild-oat-icide... or that's what Big Brother called it." The condom slid further and further along his shaft. He squirmed as she pulled the condom over his cock.

"So what do they do?"

"It makes sure that you don't get no buns in your oven when Big Brother screws you silly." She pulled the condom on as far as it would go, and then tied it down tight with the string. Now the greater part of his erection was sealed with heavy duty latex with plenty of room for his seed. The pasty fluid was supposed to guarantee that the sperm would be killed, even if by some chance the condom should tear or otherwise fail to contain the ejaculate.

"Well, it'a all set now."

"You're gonna mount your Big Brother?" asked Twilight curiously.

"Oh no... YOU IS GONNA MOUNT HIM."
