Big Macintosh's Lesson

Twilight Sparkle walked into the barn. Big Macintosh was going to meet her there today. Today, he was going to show her his 'secret mounting techniques'. She was eager to learn, and badly wanted to compare how mating worked in the real world against how it worked in her books. Against how it worked in her imagination. Against how it worked in her fantasies.
"Howdy Twilight," said Big Mac amiably. She could see the large reddish stallion with his really large cutie mark: A greenish apple cut in half. Looking at his large and iron-hard muscles made Twilight feel just a little giddy. Big Mac was a down-to-Earth Earth Pony who got ahead in the world with his sweat and blood, and the labor of his own hooves. He was standing in the back of the barn leaning on a bale of hay. His body was covered with a sheen of sweat from his labors of the day, and he even had his collar still hanging about his neck. Twilight could smell his musky body odor all the way across the barn, but it wasn't stronger than the scent of a mare ready to mate. The two scents assailed Twilight's nose as one, making her more eager to watch the mare and stallion getting it on.
"Good evening," she replied cheerfully, "I can smell your mate for the evening, so where is she?"
"Hey Valentines Chocolate," he said to someone behind the hay bale, "Twilight can smell y'all so you might as well show yourself."
A dark brown/nearly black mare rose up from behind the hay bale and smiled at Twilight. She had ebony hair, mane, and tail, her hide was spotted with dark black dots on her face and neck, and her flank was covered with her cutie mark: A cluster of three hearts made from the darkest of dark chocolates. Her eyes shown pink in the pale light of the barn.
"Big Mac," she sighed, "I'm not so sure about this."
"Look," he said bluntly, "I promised Twilight that she could study my mounting techniques, and I all can't go back on my word now. If'n it makes you that uncomfortable, I can mount y'all some other day. Is that what y'all wants?"
"No," she replied, "Let's go on. I'm too worked up to put it off any longer."
"Okay," he said nodding, "Don't want no one to think I don't think of what y'all want."
Twilight Sparkle laid her notebook open on a bale of hay, and then set a few nice new quills and a small well of ink next to it. Her eyes sparkled with the lust for learning, and her hooves quivered from all of the excitement of watching the two love ponies getting doing their four-legged play prior to mating.
Valentines waved her flank in his face as she said coyly, "Well, then don't keep me waiting either."
"Yes ma'am," he answered, "yes ma'am." He stuck his nose into her femslit, burying his nose between her nether lips as he inhaled deeply of her feminine mating smell. She quivered with delight with each deep smell he took. He shook his right hind leg a little as his cock started sliding out of its sheath.
"Oh yeah," he sighed, "that's the stuff."
He then stuck his big wet tongue deep into her femslit near the top and licked his way down towards her clit. She squirmed as he worked his spit over and into her quivering vaginal lips.
"Oh yeah," she moaned, "you're so good with that tongue. I could get off on your tongue alone if you didn't have such an incredible piece of meat down between your back legs."
As if his cock heard her, it grew more erect by at least half a foot in a couple of seconds flat.
"Keep talkin, sugar-lumps," he cooed between slurps, "cause Big Jim and the twins are in the barn, and they've come to play."
She pressed her flank harder against his snout as she moaned, "Oh, stop being cute and give me more of that incredible tongue!"
Big Mac obliged her as he thrust his big sloppy tongue deeper between her nether lips and into her vaginal opening. He pressed his mouth harder against her slit, sealing his lips around her quivering love canal opening.
"Oh yeah," she moaned, "Oh hell yeah!"
Now his boner was well past the foot mark, and still growing as he orally pleased Valentines femslit. His chin hairs tickled her clit, making it stand out from her body. She squirmed as moaned as he worked her femslit over, making it sloppy wet with both his spit and her own leaking juices.
He cast a glance over at Twilight and noted the fevered pace that she was writing in her notebook. It seemed to make sense that perhaps she was even making little sketches of him and Valentines Chocolate getting it on together.
He just had to see her notes later for himself.
Taking her tender clit in his mouth, he pinched it between his teeth and gave a long firm tug to it. The mare moaned as loud as her ever heard her moan, as just climaxed onto his snout as her sweet juices just gushed all over his nose.
He glanced at his own erection, figuring it was about half way between the first and the second foot now. "Oh yeah," he moaned, "It's comin real soon, baby."
With a real cowpie-eating grin, he used his big ole tongue to sloppily lap up her juices, although he did allow a fair amount to run down her thighs and gaskins.
"Oh yeah," she moaned, "Oh hell yeah."
Her tail waved back and forth wildly, swatting him in the face until his finally grabbed it with his hoof, and jerked it up and out of the way. He reared up over her flanks as he held up her tail, rubbing his cock against her quivering vaginal lips to coax the last half a dozen or so inches of his stallion erection to come out.
Once he was fully erect, he backed his hips up and tried to aim his cock at her opening while holding her tail with one hoof and leaning on her flank with the other. Then his cock began to glow, and like magic, it lined up perfectly with her slobbering love hole.
Big Mac glanced over at Twilight and noticed her horn was glowing now. If he wasn't so busy, he would have asked her what spell she was using on him. Perhaps he might remember to ask later. Something about not looking a gift horse in the mouth and all that.
He pressed his large cock head between her quivering lips, letting it slide into her love hole. It was strange how sensitive his cock was now that Twilight had put some kind of spell on it. He could feel the magic making it tingle from the tip all the way back to his dangling testicles.
Valentines also felt him penetrating her, making her spread her legs a little wider as he slid up within. He felt her vaginal muscles parted as his cock pressed deeper within.
"Oh yeah," she moaned louder now, "Oh hell yeah."
He gingerly stepped closer to her flanks as he pushed his throbbing cock further in. Releasing her tail now, he gripped her flank with both front hooves as he pulled her towards him. Pulled her so his cock buried itself deeper with her birthing canal.
"You're so tight," he moaned, "I loves how tight your twat is."
"You're the biggest and best I've ever had inside me," she moaned back.
"I can tell."
"Less talking!" she gasped, "MORE MOUNTING!"
He jerked her flank with his strong forelegs and drove himself at least another half a foot inside, making her gasp at the sudden intrusion. "Your wish is my command," he panted.
His erection burrowed deeper until there was only a couple of inches left outside of her.
"That's it," she gasped, "I can't take any more!"
Then things got... odd.
Big Mac could feel someone behind him. He could feel his tail being jerked up hard as some pony's hoof was getting a good feel on his horse-balls.
"Twilight," he gasped as he glanced over his shoulder, "What y'all doin back there?"
"Field work," she moaned as she stroked his tail with one hoof and fondled his rather large balls with the other.
"Oh yeah," he moaned back, "I jus loves the benefits of field work."
"What the hay?" asked Valentines, "Is this a three way now?"
"No, sugar-lumps," whimpered the big stallion, "This is just study with benefits! Oh hell yeah!"
"Pound me," she moaned, "Pound me now!"
His hips moved back and forth, a little farther with each thrust, but not so fast that Twilight lost her grip on his tail or his balls. The feeling of being in Valentine's birth canal along with the massaging of his balls was almost too much for him to take.
"That's it," she whined, "That's the stuff! Oh hell yeah!"
"Not long," he moaned loudly, "Not long. I can see the mountain now, baby!"
He pounded her pussy harder and faster, though he wondered how much more his poor tail could take with Twilight's death grip on it. But his big ole balls weren't complaining. Not in the least. A massive knot formed at the base of his cock and moved down the length of his shaft towards Valentines.
"It's the last stop!" he moaned, "The last chance to divert the train! Do I bring her in, unload on the hill, or use the side track! The load of goods don't wait for no ones!"
"Use the hill," she gasped, "Unload on the hill!"
He back out all two feet of his cock from her and laid it on her croup as he made the last few strokes to his throbbing cock with his free hoof. Now that it was out in the open, the knot shot ahead as he just blew his load all over her back. The little 'fire hose' sprayed his seed over her loins, back, and even up to the base of her withers, and then en mass over her girth, barrel and flank. It didn't take long for Valentines to look a bit like a frosted cinnamon bun, and with the hot runny frosting to boot.
"Oh yeah," she moaned, "Oh hell yeah!"
"Hey Twilight," he gasped, "Y'all wanna get a sample to study laters?"
"No hurry," she moaned, "There's plenty of time for that."
"Oh gracious," he moaned, "My balls is so tight, I'd swear you squeezed every seed outta them."
He just leaned on Valentine's back as Twilight massaged the last of his seed from him. It was freely dripping into the hay scattered all over the barn floor.
"Oh yeah," she moaned, "Oh hell yeah! See you in a couple of weeks, you SUPER STUD you!"
"What?" gasped Twilight, "She's going home like that?"
"Oh yeah," he replied, "She's takin all my love home with her."
Now that his cock was out of her, it shrank a few inches. He used his hoof to pry Twilight's hooves off of him, then turned to gaze into her eyes. His cock slapped her thigh, making an odd noise as he smiled. The last of his seed splattered her cutie mark.
He slipped his hoof under her tail, rubbed it in her slit, and then brought the dripping hoof back to his nose. She shivered as his hoof caressed her own quivering femslit, and he realized just how excited Twilight was watching him and Valentines going at each other. Sniffing deeply, his cock sprang out again back to its full length.
"Oh yeah," he moaned, "You smell so great. You's just so excited, you'd slide outta the barn with just one shove. Are you sure you ain't up for a more private lesson in mounting?"
"No," she whined, "It's too much... I can't... it's not the right time... I might be in season now..."
He hugged her tight and stroked her back with his other hoof. The hoof not covered with her hot femslit juices.
"Don't you fret none, sugar-tart," he cooed, "I ain't never forced myself on no mare no how. If you sez 'no', then 'NO' it is... But y'all can watch me jerk off if'n you wants... I can't sleeps if I don't take care of this..."
"I know," she whispered, "that you're a gentlestallion, and I can take you at your word."
"Thank you," he answered, "That all means a lot to me. It really does."
"Just hold me tight," she said as she closed her eyes, "Just hold me until your done." Her horn glowed softly as his great erection throbbed.
"Okay, I thank you," he moaned as he started stroking his boner with one hoof. He kept his clean hoof around Twilight, stroking her back and withers as he groaned softly into her ear.
"Are you studying me now?"
"No, I just want to be with you."
She rested her chin over his shoulder on his neck and throttle as she felt him pumping himself with great vigor and abandon. She imagined herself masturbating herself to sleep that night as she read her notes, looked at the anatomically correct sketches she made, and fantasized that she was the one that Big Mac was mounting instead of Valentine Chocolates.
