Air Sexi

“Alright, my passenger today is Rupert,” Muffins rehearsed to herself. “He’s another teacher who works with Frank, and he wants to visit Yakyakistan. I think I can make it if he doesn’t mind a few rest stops.”

Despite her hardships, Muffins had always tried to show a cheerful face to the world. Now that she was getting regularly eaten out and dicked up the butt, her mind was filled with cheery emotions to match her smile. As she flew towards Rupert’s home to pick him up, Muffins found herself not worrying about her unpaid bills, but wondering if her second human customer would be as cute as the first.

Sitting on Frank’s face had become the best part of Muffins’ daily lunch break. Hidden behind the counter at the post office, her submissive lover eagerly licked and kissed her to several small orgasms as she slowly nibbled her salad. He was so grateful for the chance to serve “Mistress,” he even bought her lunch every day! What a gentlecolt!

Her head filled with these pleasant memories, Muffins landed in the backyard of a small house near the Friendship School. She stepped onto the patio’s flagstones and backed up towards the door, using her wings to tidy her rear view, making sure her stockings and her tunic perfectly framed her extra large and extra desirable ass. “Your ride is ready, sir!” she called out to the house.

Muffins had thoroughly cleaned her butt before donning her uniform, just in case she got lucky with her second customer. Wouldn’t that be wonderful? Two hot guys who lived to pleasure her? It was the sort of cheesy scenario that only happened in those “erotic romances” Muffins checked out at the Ponyville Library, but a mare can dream!

Muffins looked over her shoulder nervously as her customer trod out onto the patio with hoofsteps that shook the ground. He wasn’t a human after all! He was covered in fur, definitely four-legged, and big! Big all over!

“Oh!” Muffins raised a hoof with surprise. “You’re a yak... named Rupert... that’s why you want to go to Yakyakistan...”

“Yak can’t wait to get back home and date lots of pretty cows!” Rupert dropped his voice and spoke quietly (for a yak.) “Between yak and pony, it been a long time for old Rupert!”

“Oh, I’m sorry to hear that.” Muffins’ heart pounded loudly and she felt herself begin to moisten. Submissive Frank was a cutie pie, but Rupert was more like her ex-husband: a hairy, muscular hunk!

“You know, Rupert, you’re a very handsome fellow,” Muffins couldn’t help but add. “If I were ten years younger — oh, but I bet you’ve got a whole herd of lovely ladies waiting for you at home.”

“No! Rupert shy!” Rupert bellowed in a voice that nearly knocked Muffins head over hooves. “But after month with no cow, nothing can stop yak bull from making move!”

“OK, one flight to Yakyakistan, coming right up.” Muffins gulped and scooted her butt back against Rupert’s front legs, hoping her back would hold out beneath his weight. “Just hold on to my withers, and we’ll... I hope... be ready for takeoff!”

The weight of the full grown bull nearly crushed Muffins as Rupert reared up and landed on her back, the saddle digging into his barrel and his front hooves straddling hers. Oh, dear, what had she gotten herself into? Rupert was twice her size! Muffins flapped her wings desperately, but with the massive yak atop her she couldn’t lift so much as a centimetre off the ground.

“Why pretty pony not flying?” Rupert’s deep voice rumbled through Muffins’ body, sending her staggering beneath the yak’s bulk... and setting her winking like crazy!

“Are you sure you’re using the saddle properly—w-wait, did you just call me pretty?” The mature pegasus blushed with the sudden realization.

“Sorry! Rupert not mean to be rude!”

“Please don’t apologize! It’s just that it’s been such a long time since I felt a guy hold me like this.” Muffins shuddered hungrily as the weight of the yak bull pressed onto her. She felt warm tingles deep within her, the fanning of embers that hadn’t burned for years. After all, this was the breeding position. “And you think I’m pretty... gosh...”

Muffins gasped as she suddenly felt something brush against her sensitive lower lips. It was big. And thick. And long. And shaped like a cock. “Is that your cock?” she asked cleverly.

“Ugh, Rupert knew this would happen!” Rupert cried out. “Yaks best at getting throbbing erections at worst possible times!” The large bull began to shift his weight off Muffins’ back. “Sorry, pretty pony. Rupert take cold shower and be right back!”

“W-wait... why waste it?” Muffins cautiously pushed her hips backwards, hoping for another rub against that splendid slab of yak meat, her mind made dizzy by the waves of musk pouring from Rupert’s huge, warm body. “I mean, if you’re already hard... it’d be much easier to fly you to Yakyakistan if your balls weren’t so heavy.” Yes, that definitely made sense!

“But you not yak!” Rupert’s erection said he was eager to experiment with the smaller, older pony, but this detail strangely held him back.

“That’s fine with me,” Muffins assured him. “That just means I can’t get pregnant!”

“Pony not understand. In Yakyakistan, it forbidden for yak to smash with un-yak!”

“But this ain’t Yakyakistan, mister, so get to smashing!”

“Hrm... OK! Yak down to mate if pretty pony is!” Muffins yelped as Rupert snapped his hips and slid his massive cock into her soaking pussy with one long thrust.

“Go slow!” she cried out. “Whaaah! Or fast! Fast is good, too!”

“Smash” was exactly the word! The young yak’s thrusts were hard and firm, and his cock would brook no argument. Like it or not, Muffins was Rupert’s helpless pegasus cocksleeve until he was done with her! It was a good thing indeed that she liked it — a lot!

Frank’s submissive sweetness was so much fun to play with, but there was nothing like being claimed by a hung, powerful lover! Rupert had needed a push to get started, but he was now going full steam ahead. No biped could ever pin a mare the way he was doing to her, and no human cock could go this deep. Her husband had been like this on the night Dinky was conceived... dominant and unstoppable. Not that the now-single mother wanted to stop her surprising new partner!

“Oh my gosh, Rupert, you’re fucking huge!” Muffins struggled for breath beneath the mountain of male muscle, as she was taken in a way she’d never thought she would be again.

“Unnngh... Rupert love to smash with pretty pony! Tight pony pussy underneath that fat yak ass!”

“I’ll consider that a... oh, fuck! compliment!” Every forceful slam of Rupert’s body against hers nearly knocked Muffins off her hooves. Rupert shoved his smaller partner across the patio with his thrusts, with sparks flying every time Muffins’ horseshoes scraped against the stone.

In less than a minute, Muffins felt Rupert’s cock swell even larger inside her and start to leak a stream of hot, viscous precum. It seemed a yak couldn’t last as long as a pony, let alone a human, but that was just fine — Muffins didn’t know how much more of this vigorous rutting she could take!

“Yak going to cum!” Rupert warned her. “Want yak to pull out?” Muffins’ mind frantically swam back to the surface as she tried to speak through a hot blizzard of pleasure. “Don’t you dare pull out!” she cried.

For years the unlucky pegasus had had to settle for small pleasures. A tasty meal, a romantic movie with a kiss at the end, the smile when a customer got a package they’d been expecting... Now, finally, things were changing for her. Pony stallions still overlooked her, but there were so many exotic males, from lands beyond Equestria, who considered her a mare worth knowing! Romantic movies were nice, but thick hot yak creampies were much better!

“Pony best!” Rupert bellowed. “Pretty pony best at making yak CUM!” He pushed in deeper than anypony ever had before, knocking at the entrance to Muffins’ womb and sending floods of spunk into her cervix. Muffins was far from her peak when Rupert started shooting, but the yak’s hard thrusting orgasm lasted longer than the sex! It went on for so long that Muffins was able to reach her climax, cumming all over his cock just as he finished. And what a load! Poor, pent up Rupert came as much as three pony stallions!

The tired yak slid off of her body and landed on the patio with a loud thump. “Unnngh...” Muffins moaned, her legs wobbling like a newborn foal’s. Litres of warm cream flowed from her gaping pussy with every helpless twitch and wink. She looked behind her to see Rupert lying flat on his back with his tongue fallen out, drooling saliva onto the patio.

“Oh, gosh, Rupert, are you all right?” Muffins quickly slipped her hooves around the yak’s neck and embraced the bulky stud as much as she could, kissing his shaggy face. “Don’t pass out on me now!”

“Yak never better!” Rupert reassured his lover. “Sex was great, but now pretty pony needs to carry Rupert back to Yakyakistan! Yak so drained, can’t even move!”

Muffins frowned to think of even trying to lift the mighty bull, much less carry him across Equestria. She thought quickly and snuggled against Rupert’s ear. “Are you sure you want to go back to Yakyakistan?” she whispered. “Wouldn’t you rather stay here and fuck me every day?”

“Hrm... good point! Ponyville is Rupert’s home now! Wallet is inside, on nightstand — pretty pony can take what she needs.”

Wow, that was generous! Rupert was paying her for the taxi trip, even though she’d convinced him not to go! Inside Rupert’s bedroom, Muffins gently opened the yak’s wallet with her teeth. Rupert wasn’t exactly wealthy, but what was in there would definitely help her take care of the bills that kept piling up. Muffins looked at the small stack of money longingly, but she didn’t want to overwhelm her new friend’s generosity. In the end, she took just two 20 bit bills from Rupert’s wallet, just enough to buy some new school supplies for Dinky.

As she flew home, the air flowing easily over her streamlined pilot’s uniform, her creampie dribbling out a dotted line across Ponyville, Muffins felt a bittersweet tugging at her heart. She’d now found two generous and giving lovers, but she still hadn’t completed one single trip for her air taxi business...
