Horse Riding

It was a clear and sunny day in Equestria, birds were singing and overall it’s a very peacef-

“HYAH! HYAH! HYAH! Giddy up!”

WHACK, WHACK, WHACK

“NEEEEEEEIIIIIIGGGGGGGHHHHHH!!!”

Nevermind, the sound of shouting, whipping, and whinnying echoes throughout the area as they see you, Anon, a human riding on top of a huge cyan pegasus with a rainbow mane and tail. She is about 8 feet tall, she wore riding gear, which included a saddle with stirrups, bridle, reins and a bit in her mouth. You are wearing a cowboy outfit, which consists of blue jeans, a brown jacket over a white shirt, black boots with sharp spurs attached to the boots. You are also holding a bullwhip in your right hand and tightly holding the reins in your left hand.

With each strike of your whip the mare either giggled or neighed in bliss. She was a very strong mare. Far stronger than you. And she can easily crush you if she wanted to. But that’s not happening right now. You are riding on the back of this mare, taming her and making her your own.

“HYAH! Run you mare, run your master demands it, HYAH!” You ordered as you swung your whip into her ass and roughly slammed your spurs into her barrel, making her whinny loudly as she galloped across your field which was massive, big enough for you to start your own farm if you wanted to, but this is more fun than farming.

You roughly pulled the reins back as the mare reared up, whinnied and pawed the air with her hooves.

When she came back down, “Hyah! Run Rainbow Dash! I never ordered you to stop! Only stop when I say so! I’ll show you who’s in charge like this! Hyah!” You ordered as you whipped her ass and slammed your spurs into her barrel making the mare known as Rainbow Dash whinnied in pleasure as she galloped again.

While you were dominating and taming this giant mare, you couldn’t help but think of how you ended up here.

You only recently arrived in this magical horse land. Your first introduction into this land was finding yourself in the bedroom of a very large purple horse. That was nearly two times this mare’s size. To cut a long story short, you said you came in peace, rode on her back for a bit, and then you had sex with your newfound friend Princess Twilight Sparkle.

There was just one problem. Twilight’s ass was… HUGE. No woman on Earth could hold a candle to her ass. You possessed nowhere near a cock large enough to adequately please her. Thankfully, she fixed this issue by casting a spell on your cock. Your cock grew to be a monster, it literally became about 23 inches long, or so, and 8 inches thick. Down below, you had a set of heavy balls the size of a grapefruit each. And when you ploughed into Twilight's pussy, it seemed your cock grew an additional 2 inches inside her, taking you up to 25 inches.

Within a few minutes, you were balls deep inside a sexy pony with a massive rump. What’s more, Twilight wanted you to bond with her friends, and share the love.

And since all of the mares are about 8 feet tall, you suggested that you get to mount them, by sex and horseback riding, you explained what it was and what it meant back on your world. Twilight agreed, and made a special kind of riding gear that’ll grow and shrink depending on who where’s it, which was helpful to you.

Twilight herself stood about 12 feet tall. Making her nearly the size of a full-blown elephant in some ways.

You first rode Twilight at her full size, but it was awkward since she was so big and you couldn’t do much while riding her, so she resized herself to make her the same size as the others and you had fun riding on her back, you weren’t rough with her in any way, but she apparently loved getting her ass slapped, so you used your whip quite a lot and she enjoyed it a lot.

You enjoyed it as well, as you listened to her moans in pleasure and the sound of your whip smacking her ass. This came accompanied with wonderful meaty slapping sounds of flesh, slapping against flesh as her thick bubbly cheeks smacked against each other.

After the riding was done, Twilight grew back to her normal size. (and if you didn’t know any better, you swore she seemed a little bigger than last time)

When you were thinking about who to ride next, Rainbow Dash came in and offered herself next. But she told you that she wanted to see if you could tame her and she allowed you to be as rough as you wanted, use the whip as well as your spurs as much as you wanted, and not to hold back at all which is why you are riding Rainbow Dash like a wild mare. Not only could she take what you threw at her, but she also wanted it as well.

Back in the present. You made Rainbow come to a halt, by yanking back on the reins, making her rear up as she pawed the air with her hooves and whinnied loudly. Once she came back down, she was now panting quite a lot, as she looked over her shoulder and to you as you took the bit out of her mouth as she smacked her lips against each other.

“Rainbow, before I mount you from behind could we visit Fluttershy? The mare seems scared of me. I hate seeing such a cute big mare being afraid of me.”

“Anon, if we are going to Fluttershy’s. Please, do not be rough with her. Be very gentle,” Rainbow Dash said in a stern voice. “I think you may need to have sex with her to ease the tension.”

You nodded slightly, “Yeah, I think I’ll have some gentle sex with her so that she can trust me better. Then I’ll ride on her back for a bit to let her get used to me even more and so that she can trust me better, which won’t make her feel as nervous around me.” You explained making your mount nod her head in response.

“Yeah, that’s fair. And don’t even think about using your whip or spurs on her, I can take them, but Fluttershy won’t since she’s so fragile.” Rainbow Dash replied.

“Don’t worry I wasn’t going to anyway, I’ll just gently tap her ass with a stick or something and use dummy spurs which won’t hurt in any way, it’ll just be like getting a gentle pinch.” You told Rainbow Dash, making her nod in response before she turned straight again and just stood there not doing anything.

You can tell that Rainbow is waiting for you to dismount, but you don’t feel like it. She looked over her shoulder at you, “Are you going to dismount?”

Your smirk gave her the answer as you quickly shoved the bit back into her mouth and strapped it in place, “Now why would I do that? You are a brilliant mount to ride, I don’t want to walk and since I’m in charge, I really don’t feel like it. Now hyah!” You shouted as you tagged her barrel with your spurs and slammed the whip into her ass making her whinny in pleasure before she reared up, and pawed the air with her hooves for a few seconds and when she came back down she trotted towards Fluttershy’s cottage.

Once you arrived, still mounted on Rainbow Dash, she walked up to the door, when she felt that you weren’t going to dismount she pushed open the door with her right hoof and stepped inside. You were greeted with the sight of Fluttershy laying on her couch. The mare gasped at the sight of you and brought a hoof to her muzzle.

The mare buried her head into her hooves and began to cry. “Please! No! I don’t want to be ridden! You can mount me from behind if you want! But don’t ride me!”

You and Rainbow glanced at each other, both with uncertainty in your eyes and her eyes as well, wondering if it’s too soon. But Fluttershy will have to get used to you being around her at some point, so sooner is better than later.

You nodded your head at your mount before Rainbow lowered down to her knees, allowing you to dismount as you took the bit off and all of her riding gear allowing her to extend her wings outwards as she released a sigh of relief, “Ahh, much better, I’ll tell you Anon, that saddle of your sure restraints my wings, you need to fix it so I can spread my wings even while wearing it.” Rainbow told you, making you nod in response. You’ll ask Twilight to make sure that the saddle is adjusted for pegasus wings.

You placed your hand on Rainbow’s right buttcheek. Your hand sank only about two inches into the plush softness of her ass, before meeting her ironclad muscles underneath. You pulled your hand away and watched in delight as her cheek resumed a perfectly smooth shape to it.

You walked forward and placed your hand upon Fluttershy’s three pink butterfly cutie mark. You learned that ponies love having their cutie marks rubbed. The soul of a pony’s very being was in their cutie marks upon their buttcheeks. Fluttershy whinnied softly from your loving touch.

Your hand sank deep into the plush softness of her ass by a good few inches, before meeting her strong muscles. Fluttershy’s ass was quite a bit larger than Rainbow’s far sleeker rump. You held your hand in place for a good few seconds, admiring the deep depression you made upon her buttcheek before you began to lovingly roam your hand across her cheek. You watched in delight the depression your hand made upon her cheek quickly fading away when you moved your hand to another part of her perfectly smooth cheek.

The mare moved her pink tail to the side, to reveal to you all her meaty assets. Her soaking wet marehood winked at you in greeting. And her plump ponut under her tail looked quite appetizing. You guessed ponies were very forward by nature, even if a pony had ‘shy’ in their name. It was a good thing your pants were loose and flexible. Because you were beginning to pitch an enormous tent.

“Fluttershy, would you like me to make love to you before I ride you?” you asked softly, leaning down to give a brief, soft kiss to her cutie mark. The mare blushed profusely at this romantic gesture.

“Yes, please. I need to know you will treat me nice.”

With that, you pulled down your pants and revealed your semi-erect, monstrously large cock. Fluttershy’s mouth opened in an ‘O’ shape at the sight of it. You heard the sound of clopping hooves from behind you, the next thing you knew you saw Rainbow leaning her head down over you, followed by her licking your cock, encouraging it to rise to attention. You moaned softly as the feel of Rainbow’s warm and soft equine tongue gently licking your cock. Inch by inch your cock rose until it reached a mighty height of 25 inches long. Your heavy member was thick and meaty, its girth being about 8 inches.

“Got him ready for you,” Rainbow said, as she pulled her up so you could access Flutterhshy’s ass.

You stepped forward and lay to rest your cock upon her cheek. Your heavy cock came to land upon her cheek with a heavy, meaty slapping sound. Her cheeks rippled like a stone being thrown into a lake from the impact. You sighed at the wonderful softness of her fur against your cock. You simply held your cock in place for quite some time, just to admire the softness of her ass, before you slowly began to roll your hips back and forth, rubbing your cock against her cheek. While this was happening. You could hear wet sloshing, low moans mixed in with some whinny sounds from behind you. You firmly believed Rainbow Dash was masturbating.

“Do you like that, Fluttershy?” you asked, as you stopped grinding your cock against her cheek.

“(Moan) Oh yes, it feels (Moan) nice. But can we (Moan) (Gasp) move this to my bedroom pleeeeeaaasssseeeee?” Fluttershy said in between moans with a gasp at the end, which were the cutest moans you heard, much cuter then Twilight’s and Rainbow’s moans.

Better not tell them that though, they’ll squash you otherwise with their massive asses.

“Sure,” you simply said, pulling your cock away from her cheek.

With that, Fluttershy made to stand up to her full mighty height. The massive, eight feet tall mare looked down at you with a big happy smile on her face. The mare subsequently turned around and showed you her massive backside. Her thick and bubbly cheeks were almost beach-ball-like in terms of thickness. Her marehood was soaking wet and dripping profusely onto the floor below. However, her ass was so high up, you could only reach her thick, meaty thighs.

With no further ado, Fluttershy walked into her bedroom. You followed closely behind her. Fluttershy lay herself down upon the bed and presented her massive rump to you. She was joined by Rainbow Dash, making her lay down next to her on the right. The two mares turned to one another and subsequently began to kiss one another. You could see their tongues, swirling about in each other’s open muzzles.

You smirked as you started to finger Fluttershyy’s thick and meaty pussy, earning more of her cute moans from her, before your hand disappeared in between her ass. You felt Fluttershy’s thick asscheeks clamping around your hand, trapping it in her pussy.

You tried to pull your hand away, but Fluttershy wouldn’t budge. You smirked as you came up with an idea, and started fingering her pussy again faster this time earning more cute moans from her, which were increasing by the second.

After a few minutes of fingering Fluttershy moaned loudly as she came, releasing her juices all over your hand still in her pussy, but Fluttershy released her grip on your hand allowing you to pull it out. All over your hand was dripping wet from Fluttershy’s juices. You moaned as you licked up her thick and creamy marecum covering your hand, it tasted like sweet, buttercream.

You then turned to give Rainbow some loving attention. You shifted yourself over, and positioned yourself behind her. Her marehood was soaking wet.

You smirked as Rainbow lifted her tail and shook her ass, “You still haven’t tamed me yet, stud. If you want me to submit to you, you’ll have to show that you ride me hard without stopping.” Rainbow taunted in a lustful tone.

You smirked as you leaned down next to her ear, “Not only will I tame you, I’ll make you and your friends my riding ponies and my mares, since I want the Wielders of the Elements of Harmony in my herd.” You whispered as you leaned back.

Rainbow turned her head to you, “You better be loyal. I don’t want you humping any other mares other than us six.”

You nodded in response, “Of course, you six are the only mares I need in my herd, but anything can happen. I’m not planning on taking any more sexy mares, but we’ll see.” You replied, making her nod her head slightly since you were right and anything can happen. “Besides, you all have huge asses, I think I can barely handle you all already.”

You leaned forward, and pressed your head between Rainbow’s buttcheeks, and began to lick out her succulent marehood. The mare moaned as she whinnied happily as you ate her out. Her marecum tasted like sweet skittles.

Abruptly, you pulled your head away, earning yourself a sad whine from her. However, you soon lined up your monstrous cock and slammed it into Rainbow’s pussy earning a loud and lustful whinny in response.

You started moving in and out of her, your massive cock in between her huge buttcheeks, earning a ‘plop’ sound with each thrust and making Rainbow neigh loudly in response with each movement. Your movements and her whining were insync with each other. Each time you bottomed out, her marehood welcomed you home with a tight squeeze.

Then with both hands, you roamed them across Rainbow’s ass cheeks. Feeling up her wonderful, strong rump as you pounded into her. However, you soon heard a sad whine from Fluttershy. You glanced to see her pouting with a red face. This prompted you to reach your right hand out to her, and lay in upon her cheek. You lovingly rubbed her asscheek. Your hand sank deep into the plush softness of her ass.

Meanwhile your cock plowing into Rainbow Dash's lovely pussy began to swell larger. Rainbow moaned aloud as she felt your cock push deeper into her by a good few inches. It seemed to be each mare you claimed your cock would grow a little bigger and stronger.

With renewed vigor, you thrust all the harder against Rainbow Dash's ass, slamming your massive cock back and forth into her lovely marehood. Delightful meaty smacking sounds had accompanied your thrusts as your balls slapped against her cheeks.

For about 5 minutes you continued to plow Rainbow’s pussy with your now even larger cock and playing with Fluttershy’s ass, “(Moan) (Moan) (Moan) A-(Moan)Anon, I’m (Moan) (Moan) I’m getting (Moan) close!” Rainbow shouted in between moans.

“(Grunt) (Grunt) Me (Grunt) Me too, (Grunt) you better (Grunt) (Grunt) take every-(Grunt) everything (Grunt) in!” You shouted back.

“(Moan) I (Moan) I will! I’ll (Moan) (Moan) take everything! (Moan)!” You slammed your hips against her one last time, driving your huge cock deep inside her, before unleashing a massive explosion of your creamy love inside her as Rainbow neighed so loudly that Fluttershy lowered her ears to lower the sound for her.

You fucked her through your release, releasing spurt, after spurt of your love essence inside her. You sighed in bliss as you finally came to stop as Rainbow fell on the bed with a happy expression, her eyes rolled into the back of her head and her tongue hanging out the side of her mouth. However, you did not lose your erection. Your now even bigger cock was ready for more action. You pulled your still hard member out of Rainbow, as a waterfall of both yours and her cum came gushing out of her marehood.

You slowly turned to Fluttershy who is blushing at your expression as her pussy is dripping again. You moved to her behind, as you positioned your wet cock in front of her pussy, you turned to her, looking for permission, she nodded slowly making you smile, “Don’t worry Shy, I’ll be gentle.” You said making Fluttershy nod softly in response.

Slowly, and gently you pushed your cock inside her. The moment your thick tip entered Fluttershy uttered a wail of grief. You stopped, momentarily, before you began to push inside her. Inch by inch, your massive cock pushed apart her walls. Fluttershy was clearly a virgin, you could see blood dripping out of her pussy. You did not protest, Fluttershy needed you, and you were going to make her first time magical and worth remembering.

Eventually, your cock came to kiss her deepest barrier and you in one swift motion, broke the barrier making Fluttershy scream quite loudly as tears started flowing out of her eyes. You place your hands on either side of her cheeks, and gripped her cutie marks. Lovingly and gently you rubbed her cheeks to ease the pain and distract the mare from the pain from the huge cock inside her.

You felt your cock twitching inside Fluttershy as it swelled even larger again in size. Fluttershy uttered a loud whinny of pain as she felt your cock stretching her walls further apart.

“You…(Moan) you… (moan) got… even… (Moan) bigger again,” she said in between moans, and panting of her breath.

You gave her a sheepish smile. “Yeah, sorry about that Fluttershy. It seems I just claimed you.”

You waited for quite some time. Until Fluttershy calmed down. Her breathing slowed down, before she turned to you and spoke to you. “I’m…. ready… but go slowly.” Fluttershy whimpered with tears still coming out of her eyes.

You made a vow to yourself to never let Fluttershy cry again, because you felt like it was against the law to make this beautiful, sweet, and loving mare cry no matter what.

With that, you pulled back by a mere inch, before you came gently smacking your hips against her backside. Fluttershy whinnied happily at the feel of your gentle thrust. You did the same again, by pulling back by a mere inch, before lightly thrusting back into her again.

Gradually, over time, you had pulled back further and further each time you thrust back into Fluttershy. You tenderly made love to the mare. Your hands gently massaged her cutie marks during your gentle thrusts. The softness of her cheeks was like that of memory foam, they melded to your touch, your hands sinking deeply into them. You smiled at the sight of Fluttershy wagging her tail excitedly. Her tail came to lightly slap your face during her wagging.

You were earning the trust of your new steed by making sweet love to her. And she was just one of your six mares you were going to make love to soon, “I’m going to need to have saddles built for all of them and maybe even some crops and whips for Rainbow and any other mare who loves to be whipped or who needs to be tamed.” You thought to yourself before smirking at the thought of you using your whips and you started thinking about Rainbow Dash’s ass having a lot of red welts from your whip.

Maybe Rainbow would like to become your personal riding horse since she doesn't do much in the first place, since Applejack told you that she likes to take naps most of the time. And if Rainbow doesn’t agree, you’ll just have to ‘persuade’ her in a few ways. They will be fun for you and Rainbow Dash.

“F-faster,” Fluttershy begged, breaking you out of your thoughts and turned to her. “Eeep… a little faster.”

You began to pick up a little speed, your balls coming to lightly smack against her ass. This created a wonderful rippling effect like a stone being thrown into a lake across the thick cheeks of her ass. Fluttershy softly moaned and neighed happily as you thrust back and forth against her wonderful, plump backside.

From hearing this, you were encouraged to thrust faster into Fluttershy. The mare uttered loud whinnies of pure bliss as your cock slammed into her. Her marehood clamped down hard on your cock, trying to coax you to release your seed.

“Anon….” came her voice low, and soft.

“Yes, Fluttershy?” you asked sweetly.

“Make me your mount,” she begged.

That was all you needed to hear, as you pulled back to the point of nearly exiting her marehood, before slamming back home deep into her pussy, before you subsequently unleashed a huge explosion of your creamy human spunk inside her, the mare cried out a loud neigh as the feel of your seed pumping into her.

Spurt, after spurt of your human cum came blasting into the beautiful mare. You could see her pink butterfly cutie marks glowing with blinding light. The mare subsequently began to grow larger, her rump air ballooning out from behind her, you ended up being pushed back as her rump inflated in size. Your jaw dropped in utter shock, as the mare rapidly grew into the air before you.

Her big buttery yellow ass became even bigger before you. Rather than be scared this pushed you on to mount your mare even harder, each and every spurt of your seed caused her to gain several more inches into the air.

Her growth came to an abrupt stop when she reached about 12 feet tall, making her about the same size as Twilight. Her size was nearly a full-blown elephant in some ways.

You tenderly rubbed the thick cheeks of her ass, feeling up the plush softness of her now extra thickness. Your hands sank like soft memory foam into the squishy softness of her cheeks. You were tempted to have sex with her even more to see if her ass would get even bigger.

“Oh… my,” she said, blushing in embarrassment at her much larger body size.

Your mouth widened in shock, you heard soft moaning coming from the other side of the bed, making both of you turn and saw Rainbow waking up, “(Yawn) Hey guys, what’s uuuuppppppp . . .” Rainbow said before trailing off as she laid her eyes on Fluttershy.

“Ummmm . . . I . . . I don’t know how this happened.” You said, but Rainbow didn’t seem to listen as she stared at Fluttershy, before you saw her eyes going down to Fluttershy’s massive asscheeks which were the size of beach balls at the very least as you saw Rainbow pouting as well as her cheeks upon her face red with a blush.

Sensing Rainbow was upset, you made to pull your cock out from between Fluttershy’s cheeks. You made your way back to Rainbow, and placed your loving hand on her right cutie mark. You hand sinking in by at least 2 inches into her plush softness before meeting her strong and firm muscles underneath.

“Don’t worry Rainbow, I’ll make you big as well, one day.” You said.

“You better,” she said in a bitter tone making you chuckle at her tone as you started to pat her plump ass making her moan.

Without a word, you made to lay down next to Rainbow. You rested your hands upon her back, while pushing your cock between her cheeks, and into her marehood. Rainbow gasped at the sudden feeling of your cock inside her pussy. Tenderly you rocked your hips against her, gently thrusting your cock in and out of her marehood. Rainbow sighed happily and closed her eyes.

“Feeling better?” You asked.

Rainbow nodded happily, “Much, mmmmmuuuuuuch better, (Sigh)” Rainbow replied before sighing in pleasure at the end.

You smiled for a bit, before smirking, “Good, but I hope you didn’t think it was over. Far from it my little pony.” You replied as you gently slid your cock deeper into her marehood making her whinny in pleasure.

You tenderly made love to Rainbow. You did it slowly and gently. Eventually, you found yourself drifting off to sleep, while still hard, and deep inside your mare. Rainbow went to sleep with a smile on her face. She felt loved.

Fluttershy laid herself down next to you, and gave you a full view of her ass. Her massive ass. Rainbow’s ass could not hope to compare to the size of it. You went to sleep between two huge mares’ asses on either side of you.

After a good sleep you woke up, finding yourself in between Rainbow and Fluttershy as their manes are all over your body, which felt warm and soft against your bare skin, it felt like a soft and silky blanket was on top of you.

You smiled as you gently patted their manes, you also noticed that Fluttershy’s size returned to normal making you sigh in relief since you really didn’t want to explain why Fluttershy had a growth spurt. A small part of you wished to see her bigger again, seeing that ass was hot, you also wished that Rainbow would be able to have an ass like that one day as well.

You pulled your cock out from the warm embrace of Rainbow’s marehood. You lovingly stroked the sleeping mare’s cutie mark. Feeling up her ass, and it earned a cute moan from her in her sleep. Your hand sank by at least two inches into her cheek, before meeting her strong muscles underneath.

You pulled your hand away and then turned to Fluttershy. You laid your hand upon her cutie mark. You watched in delight as your hand sank far deeper into Fluttershy’s ass much thicker rump. It was buttery soft and squishy. It also earned you the cutest moan you’ve ever heard in your life and it made your heart melt at that.

As if you were rewarded for your love, her ass grew by several inches with a small growth spurt. You hope the other mares would get temporarily bigger from your love. Watching Fluttershy’s ass grow drove you wild with lust.

You were tempted to make her ass even bigger, but you had other things to do, like getting a drink, your throat is as dry as a desert.

Soon you managed to sneak out of the bed and walked to the kitchen where you drank some water, you turned and saw it was 3pm, “Damn, we slept for awhile.” You exclaimed a bit in surprise, but considering you were screwing the brains out of Rainbow and Fluttershy, you weren’t surprised.

Soon Fluttershy came down to the kitchen, “Hello Anon.” Fluttershy greeted you.

You walked up to Fluttershy and kissed her snout, making her giggle, “And a hello to you too Fluttershy.” You replied.

You filled a cup of water for her, sat down on a chair with her sitting on the opposite end, you handed her cup to her, “Thank you.” Fluttershy thanked before she grabbed the cup and drunk the whole thing in one go, you followed suit, since after that hard sex you were thirsty.

Once you and Fluttershy finished, Fluttershy let out a very soft burp and you soon released a burp of your own, “Excuse me.” Both you and Fluttershy said at the same time, causing you two to look at each other, before you chuckled and she giggled.

After a bit, you figured now you would ask, “Hey Fluttershy?” You gained her attention, “Are you ready?” You asked.

FLuttershy’s eyes widened slightly before she lowered them and slowly nodded her head, “Y-yes, b-but . . . p-please don’t use tho-those things on me.” FLuttershy muttered softly, but you heard it and nodded in response.

“Don’t worry Fluttershy, I only use the crop and spurs on those who can handle it or they ask for it.” You replied.

“D-did Rainbow ask you to use those things on her?” She asked out of curiosity.

“Not really, the first time I rode on her back, she threw me off, since I couldn't tame her, so I figured the best way to tame her was to use a crop and those sharp spurs on her. You wouldn't believe how long I had to stay on her back as she bucked and jumped. I will say she wasn’t expecting me to have those things, but it worked.” You explained making Fluttershy nod slowly.

“O-ok, I understand, just don’t use them on me p-please.” Fluttershy said.

“Don’t worry, I won’t. We’ll take it nice and slow at your pace, okay?” You asked, making her nod in response.

You stood up, put both cups in the sink, walked upstairs to put your clothes on, you also grabbed the bridle made just for Fluttershy as well as the saddle, walked back down, where you saw her in the living room, you both walked outside, once you were in a good area, you started attaching the riding tack to your new mount. The saddle fitted nicely after it adjusted to her size, then you strapped the bridle in, placed the bit into her mouth, making her shiver at the taste.

Once she was ready, you removed the spurs from your boots, placed them in your jacket pocket, walked up to Fluttershy, placed your left foot in the stirrup, you felt Fluttershy tensing, so you gently rubbed her mane to soothe her, “Don’t worry as I said, we’ll do things at your pace.” You soothe her, making her nod in response as she relaxes slightly.

You jumped up, slipped your right foot in the other stirrup as you planted yourself on the saddle and now Fluttershy is carrying your full weight.

You gently held the reins, tugged them from the left and right side making her turn her head obediently, “(Click) (Click) (Click) Let’s go girl.” You said as you gently tapped her barrel with your boots three times making her release the cutest squeak you ever heard in your life as your new mount started walking around the field.

Every time Fluttershy did something right, like following your orders, speeding up when you wanted to, or slowed down, changing direction, you would pat her mane. But she did do a few things wrong, which wasn’t a surprise, since this is the first time she had a rider on her back

After a bit more riding, you leaned to Fluttershy’s ear, “You ready to kick this up a notch?” You asked before blowing into her ear making her shiver and moan softly.

“Yeeeeessssss.” Fluttershy whispered back in a moan.

You leaned back, before raising your right hand in the air, before swinging it down onto Fluttershy’s ass making her squeak in surprise before she trotted down a forest path away from her house. But you didn’t want to go too far from her house, so you reined her back around towards her house, slapped her ass again, which earned another surprise squeak from your new mount and another burst of speed.

Each time your hand made contact with Fluttershy’s soft and plushy ass, your hand would sink into it, before you lifted it up to slap it again. Each slap would either make Fluttershy moan at the slap or release a squeak in surprise which both ways resulted in her picking up her pace and encouraging you to slap her ass again.

The mare before you craned her neck back, uttering a loud moan, her tongue lolling out her mouth which was slightly hard since she has a bit in her mouth. You saw your elevation noticeably change as she jumped in height by several inches. You heard a thunderous meaty slapping sound as her rump became larger behind her.

“Whoa girl!” you said, pulling on her reins. The mare uttered a heart broken whine. She turned back to look at you with puppy dog eyes.

You chuckled, before leaning to kiss her forehead, “I’m not mad at you girl, you are a good mount to ride and lots of fun as well, especially each time I slap your beautiful and soft ass it grows each time.” You said in a soft yet dominating tone, making Fluttershy blush as she started to drip fluids out of her body.

You continued. “I would be lying if I said I didn’t like to see you grow. Besides, if you grow too big, I’ll happily dismount and ride you from behind.”

“W-w-while t-th-that wo-wou-would be n-nice. I th-think we sh-should sa-save th-that fo-fo th-the bed.” Fluttershy shuttered in a blushing mess on her face.

You chuckled at that, “Ok, well, how about we get back to our fun outside?” You suggested making her nod in response before she turned straight again, “Hyah!” You shouted as you slapped her soft and plushy ass again making her moan as she trotted again.

Her ass was more jiggly than ever at its larger size. You heard a meaty slapping sound as her buttcheek clapped together. You could never get bored hearing that and Fluttershy’s moan.

Fluttershy meanwhile was hot and aroused and she is getting more aroused each time you slapped her. She grew a little bigger each time.

After 30 minutes of riding and Fluttershy being slapped on her ass, but now her right yellow ass cheek has a nice red hand print on it. You could barely ride on Fluttershy’s back anymore. She was quite frankly massive. If you had a guess she must have been about as tall as a giraffe or so. Her buttcheeks were ginormous, each one about the size of beach balls each, an extra large one.

You were lucky that her saddle, reins and bit grew to match a pony’s size. Once you were outside of Fluttershy’s cottage, she kneeled down, so you can dismount, once you dismounted, you took off the riding tack.

“Excuse me Anon.” Fluttershy whispered, but you heard her, as you turned to her, “Can I do something please?” Fluttershy asked.

“What is it, Fluttershy?” you said softly.

“I want you. But I want to be on top. Twilight told me you were perfectly fine when she was on top when you first met. There seems to be weight protection when a pony sits on you.”

“Yeah, that’s fair Fluttershy. I don’t mind you taking me for a ride.”

Fluttershy turned around… and showed you her gigantic backside. Her marehood was soaking wet, and dripping thick and creamy liquid onto the ground below. Her thighs were thicker than your own torso. They were like huge wine barrels. She was so tall, you could not even reach her ass anymore without her bending down.

You chuckled at the sight, making Fluttershy blush even more, “Do-do-don’t l-l-lau-laugh.” Fluttershy squeaked out in embarrassment.

“Sorry, it’s just that you’re dripping even more than Twilight did.” You replied, before you took out your cock. You had a good 29 inches now, but that was nowhere near the size needed for this mare.

You shrugged your shoulders, before making yourself lay down on the ground. Fluttershy gently laid her massive rump down upon you, covering the entirety of your body. You were smothered in her great, warm, bubbly softness. You hissed in pain from her great weight. You were certainly taken for a ride.

Your cock rose upward to go into Fluttershy’s marehood above. In certain situations your cock would grow temporarily larger. The mare moaned softly as your growing cock came to plunge into her depths, inch by inch. For quite some time, Fluttershy remained there, sitting on you with her massive ass as you pushed further and further into her.

You on the other hand were busy worshipping that massive ass of hers. Tears of joy were in your eyes. You watched your hands sink deeply into the squishy softness of her thick cheeks, it melded like memory foam to the touch. You uttered a muffled moan into her asscheek.

Fluttershy raised her massive ass high into the air, before she started to bounce up and down upon you, each time making your cock go deeper into her marehood. You could hear her massive buttcheeks clapping together each time she bounced. Surprisingly, she didn’t seem to grow any further. Normally, you would last much longer. But you found yourself near release already. Fluttershy’s ass was just too wonderful.

You can hear Fluttershy’s moans getting louder and louder with each bounce she made and plunging your cock deeper and deeper into her marehood and her size growing inch by inch, which made her already massive ass grow even more. It inflated like a balloon.

“(Grunt) (Grunt) (Grunt) (Grunt), Fl-(Grunt) Flutter- (Grunt) Fluttershy, I-I’m (Grunt) (Grunt) (Grunt) I’m getting close!” You shouted which was muffled due to you being buried by her buttcheek smothering your face.

“(Moan) (Moan) (Moan) (Moan) (Moan) Y-y-y-yes (Moan) (Moan) s-s-so a-am I An-Anon (Moan) (Moan) (Moan) (Moan)!” Fluttershy shouted in between moans.

“(Grunt) (Grunt) (Grunt) Y-you be-better take (Grunt) (Grunt) every last drop (Grunt)!” You shouted again.

“AAAAANNNNNNNOOOOOONNNNNN!!”

“FFFFFFLLLLLUUUUUTTTTTEEEERRRRSSSSSHHHHHYYYY!!”

Both Fluttershy and you, screamed and shouted so loudly that birds flew away from the sound scared as you shot your load into her as she cummed all over you, drenching you in her cum, Spurt, after spurt of your seed shot into her, each one causing her to have a violent surge of growth.

You could hear trees being knocked over, and smashed by her growing asscheeks. When her growth subsided, you were buried deep into the Earth below from under her mega large asscheeks.

“Oh…. my,” Fluttershy said, blushing as she stood at least 40 feet tall. Two times larger than a two story house.

Your muffled voice managed to get through to Fluttershy as she removed herself showing her two large buttcheek marks, which created deep craters underneath her. You took a few deep breaths, but you managed to regain your breathing as you looked up to the massive Fluttershy who looked embarrassed. Each cheek of her ass was like that of a British double decker bus at this point. On a side note, your cock shrunk back down to normal size, 29 inches.

You slowly stood up, realizing that you were drenched in cum and you smelled like it too, you looked up to the large mare again, “Can I borrow your shower?” You asked.

Fluttershy nodded, “Of course you can Anon, anything for you.” She replied as you figured that you should wait until her growth spur wore off.

Fluttershy slowly lost inch by inch, until she went back down to ‘mere’ 8 feet tall. To be honest, even at her base size. She was still huge. You remounted your mare, but didn’t slap her ass since you didn’t want her growing again . . . yet, and thus you rode her back to her cottage.

(Timeskip)

“Good bye Anon and Rainbow.” Fluttershy waved you and Rainbow Dash. You are mounted on Rainbow again, you had clean clothes on, you had a shower to get rid of the smell of sex. Your boots have the sharp spurs reattached, you are holding your whip in your right hand while holding the reins in your left and your mount is wearing her tack.

“Yeah same Fluttershy, and I’ll let you know when I’m in the mood for a ride on you.” You replied with a wink making her blush slightly but nodded happily before she started to close the door.

Once Fluttershy closed the door, you roughly pulled the reins in the opposite direction making Rainbow moan slightly, when she is facing the direction of your home, “Hyah! Giddy up! We have a lot of time to make up for you sleeping you lazy mare! HYAH, HYAH, HYAH!!” You shouted as you slammed your spurs into her barrel and slashed her ass with the whip each time you shouted ‘hyah’, making her whinny in pleasure and pain. She moaned in most pleasure as she galloped away from Fluttershy’s house.

You continued to spur and whip Rainbow Dash to make sure that she’s giving her all, to please you as her rider.

Once you were far enough from Fluttershy’s house, you pulled the reins bringing your motun to a halt, you tapped your spurs into her barrel, making her walk, “So Rainbow?” You called out making Rainbow look over her shoulder at you, as you took the bit out of her mouth, “I know that you don’t do much these days.” You started.

“Hey! I’ll have you know, that I do a lot these days!” Rainbow protested.

You raised an eyebrow, “Really, like what?” You asked.

“Napping and if not that, then training to one day be a member of the Wonderbolts.” Rainbow answered with her eyes closed and her nose lifted.

You sighed, “Then I guess I’ll have to find a different mare then.” You said in a fake sadness tone.

You saw Rainbow open her eyes and look at you again, “For what?” She asked.

“Well, you see, since you ponies are huge and I’m not as tall, I may need a personal riding pony to ride and for long distances as well. But since you’re busy I’ll find some-”

“No, no, no, no! I’ll do it, I’ll do it!” Rainbow interrupted you, making you smirk on the inside.

“Really?” You asked.

“Yeah I’ll do it, since we can spend more time together if I’m your personal riding pony.” Rainbow replied.

“If you do, I get to treat you however I want, since ponies on my world don't complain to their rider, you know that right?” You said with a smirk.

Rainbow smirked back, “Ohh, I think I can handle anything you throw my way, just don’t put ourselves in a dangerous position. But other than that, I can handle anything.” Rainbow replied.

You smiled in happiness, “Well then, I think I need to test out my new riding pony, are you ready?” You asked.

“Always stud.” Rainbow replied as you placed the bit back into her mouth as she turned straight, and took a firm hold of the reins.

“Hi-ho Rainbow Dash away!”

WHACK, WHACK, WHACK

THUD, THUD, THUD

You shouted as you slammed the whip into Rainbow Dash’s ass and tagged her barrel with your spurs three times, making her whinny in pleasure and slightly in pain, but mostly pleasure, as she reared up, pawed the air with her hooves and whinnied loudly.

When she came back down she galloped away, “I think I’ll go after Rarity and Applejack next. I know Applejack will want me to tame her, but I’m ready for her.” You thought to yourself as you slashed the whip across your mounts ass again making her gallop even faster.

You are currently with Applejack somewhere in the Apple Orchard far away from the barn, you are far away because your soon-to-be fourth mount didn't want her sister to see what was going to happen, so she led you away from the barn and into an open area with nopony around.

It’s been about a week since you made Rainbow and Fluttershy your mares, while Rainbow is your new personal riding mare. You kept your promise and you treated her like how humans would treat horses back on earth, which was good, but you decided that you needed to tame her and make her yours, so you spent an entire day making sure that Rainbow had everything needed to be your perfect riding pony. And by that you got more whips and sharper spurs that can really get her moving and make her move faster.

You spent that day on Rainbow all day long, riding her the whole time, never leaving her back once, even as she ate and drunk, you sat on her back . . . apart from you having to go to the bathroom, you spent the whole day on her, riding her hard always cropping her with your whips, crops and tagging her barrel with your spurs if she slowed down even a little, you would make her run back to paste.

You even rode her through the village, at first a lot of ponies were surprised, but when they saw the happy look on Rainbow’s face they figured that she wanted you riding her, so it went by as normal after that.

You even had a bucking session where you managed to stay mounted to bareback Rainbow Dash, she only had her bit and bridle on her, as you had a pair of wicked spurs attached to your boots. You managed to stay mounted for nearly half an hour before she gave up, but you didn’t dismount after that no, you slammed your wicked spurs into her barrel which made her whinny in pain and pleasure before she galloped around

At the end of that day Rainbow was so exhausted that she fell asleep on the couch, but the following day you rewarded her with a massage and healing gel on her flank, since by the end of the day it was covered in red welts and on her back legs since they were purple from the spurs begging tagged into her.

For the next day she wasn’t up for riding since she didn’t have any energy, she was tired and sore from how hard you pushed her, so you let her rest the next day. But the day after that you pushed her even harder in order to train her so she won’t be sore in the future, and you hardly gave her any breaks that day.

You know that this training is harsh, but it’ll be worth it for when Rainbow is able to carry you without getting sore ever again. So you stuck to the training to toughen and strengthen your riding mare.

For intensive exercise you made sweet love to her and Fluttershy. Your cock seemed to have grown bigger and stronger, even without claiming another mare. Your cock stood 31 inches long now. Your love only got more passionate every night. Pony magic seemed to be seeping into your body, amplifying your strength.

And one day as you were riding Rainbow, Twilight came back and challenged Rainbow to a race in order to see who will be your riding pony. While Rainbow was smaller then Twilight she won, since she has a better athletic build then the princess does.

You told Twilight that she’ll be your riding pony for when Rainbow can be, since she’s your second personal riding pony, which you could tell she wasn’t too happy about it. But she accepted it since it’s better to be one then not one at all.

Twilight was a little upset that she lost and felt as if she wasn’t loved anymore. But you made sweet love to her to make her feel happy.

“Listen here, sugarcube.” Applejack said breaking you out of your thoughts as you turned to her, “You aint putin’ that stuff on me. It ain't natural.” Applejack said as you were about to put the saddle on her back.

“Ok, fine, I’ll just ride you bareback. But I need to put the bit in, otherwise I’ll have to hold on to your mane.” You replied.

“Fine, but it better be loose. I want to talk to ya.” You nodded as you removed the bit from the bridle, so it’s a bitless bridle, allowing her to talk and it will allow you to steer her as well.

When you strapped the bit to her head, you jumped up and landed on the middle of her back making her breath out slightly, but didn’t grunt or anything.

“I’ll let ya on mah back. As long as there aint no funny business. Ya are mah friend, nothin’ more.”

You nodded, “I understand.” You replied, ‘For now, we are anyway before I tame you.’ You thought to yourself with the same expression to give nothing away.

Cheekly, you raised your hand up above her asscheek. “Hold up there, partner. I said no funny business. But if ya want funny business, ya ain't taming me, unless ya have Rarity. I will kick you right off unless I have Rarity to kiss me."

You stopped, as you sighed in defeat as you withdrew your hand, “Ok, I understand.” You replied a bit saddened, but it also made you determined to make this mare yours, but in order to do that, you have to show her that you can tame her and for that you need Rarity for that.

But then you thought that this is a good way to get two new riding mares at once, but you need Rarity to tame Applejack.

So until Rarity shows up, you’ll have to take it easy, “Alright then, let’s go.” You swished the reins and tapped her barrel with your heels, you aren’t wearing spurs since Applejack wouldn’t have any of that gear you use on Rainbow.

Applejack started walking in a random direction since you won’t be able to do any hard riding, so you decided to take a casual stroll through the apple farm since you haven’t done that during the time you’ve been here.

You found yourself unable to hold back, and you roamed your hand through her soft, blonde mane, earning you a happy moan. Applejack, however, soon turned around to give you an angry glare. “Watch yourself there, partner. Ah don’t want to hurt ya, but ya are being mighty inappropriate,” she said sternly.

You raised an eyebrow, “How is petting your mane inappropriate?” You asked confused.

Applejack opened her mouth but closed it before she turned straight, not facing you, “It just is, partner. Ya hands do feel nice, but you aint doing anything funny with them to me without Rarity here.” Applejack replied.

Your expression became a bit saddened by the way she’s acting, ‘I’m starting to think she doesn’t want me here at all.’ You thought to yourself, “Okay, I won’t do anything then. I won’t praise you or pet you for when you do something good.” You replied a bit saddened with how Applejack was acting with her nodding in response.

“Good . . . wait what?” Applejack asked at the end when you said you won’t praise her.

“Let’s go.” You quickly said as you tapped her barrel with your heels as she continued walking down the dirt path.

You continued down the path, you are still riding on Applejack’s back. You can tell that she wanted to hear some sort of praise or anything from you, since you haven’t said a word since you ordered her to move. Since then you only made rein tugs and barrel taps with your heels to steer her and make her move. But you weren’t going to break, since she started this.

This continued for a while now, until you heard Applejack sighing with her head down, before looking over her shoulder at you, “Sorry, but I don’t feel comfortable without my marefriend. I’ll tell ya what partner, ya get Rarity here I'll let ya feel me up all you want. I'll even allow ya to rut me. Ya can go to town on my ass all you want then. I promise I won't buck then.”

“You promise? You’ll let me freely manhandle you?”

“Yep. I’ll even let you use those spurs and whip on me for an entire day if yah want.” Applejack said since she realized that she was being mean to you.

“I’ll promise not to abuse the offer you gave me. I will treat you well. I don’t like hurting my mares.”

Applejack raised an eyebrow, “Yah sure treat Rainbow rough, I’ve seen the way yah rode her when yah rode her through the village.” She replied, making you chuckle at her response.

“Yeah, but that’s because she agreed to it, as well as she lets me do that. She is a very strong mare. She recovers quickly and I knows she enjoys when I use the hardcore gear on her, since it makes her hot. In fact, Rainbow seems stronger than ever. I am very gentle with Fluttershy. Hell, I don’t even use the whip or spurs at all, I just gently tap her flunk with the crop and gently tap my heels into her barrel.” You replied as Applejack listened to you as it was her turn to raise an eyebrow.

“How did ya get Fluttershy to agree to let you ride her. She told me she was terrified, and she wouldn’t let yah ride her.”

“I made love to Fluttershy before I even got on her back to earn her trust. And I was happy to do so.” You replied as she stared at you most likely to find any form of lying since Twilight told you Applejack can tell who’s lying due to her element.

“Ya got the equipment for that?” She asked.

“Yeah, my cock has gotten bigger and stronger making love to ponies. Twilight suspects pony magic is leaking into me. My cock seems to get just a little bit bigger each new mare I make love to. I am 31 inches long now.”

Applejack jaw dropped, drooling a little. “Ya aint lying, and I’ll be lying if Ah said ah don’t want to experience it.”

On the outside you didn’t show any reaction, but on the inside you were smirking, “I almost got her, now I just need to make sure she really wants to do that and I know just the way.” You thought to yourself, “Well, while you and Rarity have your own sexy time with each other.” You replied before you leaned down to her ear.

“Imagine it, you and Rarity kissing each other, while I rut you from behind the same way I made me tame Rainbow and Fluttershy. Imagine what that would be like?” You whispered as you blew into her ear sending shivers down her body, before she managed to compose herself.

“Ya lucky Rarity likes ya. She wants ya to ride me. So, she won’t be mad if we do it in front of her,” Applejack lowered herself to the ground. “Ya better get to work on mah rump. Ya have mah permission to go crazy on mah ass.”

“Ok, also how about we make this interesting?” You proposed making her raise an eyebrow.

“Go on.” Applejack answered.

“Well, I bet that if I can make you feel good, then I get to use some of the lesser stuff that I’ve been using on Rainbow on you during our ride back.” You flipped your backpack around and took out a whip and spurs that weren’t as sharp.

Applejack stared at them for a bit, until she turned to you, “And what do ahh get when ahh win?” Applejack asked.

You thought about it for a bit but you couldn’t think of anything, “I’ll let… you errr… ride me?”

“Ya too small for that. But I guess I can go cowgirl on you from sunrise to sunset. How does that sound?”

“Exhausting, but sexy, so long as I get to ride you off into the sunset on your back while using my gear.”

“Ya don’t understand. Ya be lying on the ground while ah be bouncing mah big fat ass on you all day.”

You smirked, “Oh trust me I understand, but I’m just saying my part for when I win.” You replied.

Applejack smirked back, “Not gonna happen partner since I’m gonna win.” Applejack replied. “You’ll enjoy yourself, even if you lose.”

“I know but I won’t lose so I’ll be able to get a good ride out of you.” You told her with both of your smirks growing to the max.

“Shake on it.” She spat on her hoof, and presented to you. Without hesitation you shook her hoof, even with her saliva on it. Her mane feels soft and warm to the touch, and slightly wet due to her spit.

Your smirk on the inside grew to the max, “Hook, line and sinker, now all I have to do is make her mine and she won’t be able to resist me riding on her back or me riding her from behind.” You thought to yourself.

“Before we begin, I need you to drink a counter-growth potion,” you said, pulling out a small, glass vial from your pocket.

“Why do ah need to take this?” Applejack asked.

You sighed slightly, “Allow me to demonstrate,” you said, pulling your hand back, and delivering a hard slap to her buttcheek. Applejack moaned as she gained several inches in height. Her buttcheeks slapped together with a loud meaty slapping sound of flesh, slapping against flesh.

“Ah see. That growth did feel nice,” Applejack looked at her slightly wet marehood, and admired her even larger backside.

You responded with a deadpan expression, “Yeah so you’ll need the potion so that you won’t grow the size of Twilight since it happened to Fluttershy before, so I asked Zecora to make anti-growth potions. So take it.” you opened the lid, put it against Applejack’s lips, and lifted it up as she drank the whole thing in one go.

“Is anti-growth only temporary?” Applejack asked.

“Yeah, I would love to see your ass and body get bigger one day,” you answered.

When she finished her body became surrounded by a pink aura for a few seconds before it faded, “Now then where were we?” You asked as you put the empty bottle back in your back and tossed your bag to one side.

You dismounted Applejack, then you positioned yourself behind her, pulling down your pants. Then without any warning, you slammed your massive cock, passed her asscheeks and into her pussy, making Applejack whinnied in pleasure at being roughly penetrated.

“Ahhh, ya bigger than the biggest stallion I shared with Rarity’s before.”

You smirked at that, “Yeah trust me AJ, when I’m done with you, you’ll forget about that stallion and you’ll be begging me to have Rarity into the mix.” You replied as you continued to pull in and out of her pussy, each time making her moan louder and louder, ”Each mare I claim my cock only gets a little bigger and stronger and I make each mare feel better and better.”

“(Moan) Y- (Moan) Yah got (Moan) (Moan) th- (Moan) that right (Moan) partner.” Applejack shouted in between moans and whinnies. ‘Plat’ ‘plat’ ‘plat’ came your balls smacking against her lovely, plump backside, a wonderful meaty slapping sound of flesh, slapping against flesh,

You can also hear a ‘Plop’, ‘Plop’, ‘Plop’, sound each time your cock was pushing into her pussy as well. You roamed your hands over her large rump, feeling up it’s plush softness, digging into the thick bubbly layers of soft fat, before you met her strong applebucking muscles underneath by at least a good few inches.

They felt firm, but not hard, as that was all muscle, not a hint of fatness in her legs and her fur was soft to the touch as well. Applejacks legs began to tremble, before her legs buckled and she collapsed onto the ground in a heap, in so doing you slammed hard into her ass with a meaty slap, causing her to utter a loud, heated whinny of pure bliss as your massive cock plowed deep inside her.

Giving her no time to recover, you immediately pulled back and began to rapidly piston your hips against her, the force of gravity downward increasing the strength of your slams against her ass. Furthermore your cock began to grow larger inside by at least a good few inches. It seemed you already claimed her, but it would be cruel to pull out now and leave this mare unsatisfied.

“Ooooh…. Ya are getting bigger!”” she cried out.

Applejack’s tongue lolled out of her mouth, the mare was reduced to a quivering mess as you pound away upon her rump, non stop with your now even bigger and stronger cock. You could hear the sound of clopping hooves from behind you. You now stood at a mighty 35 inches inside her with your cock. The claiming effects seemed to be stronger upon this stubborn mare.

While still thrusting with your even larger cock into Applejack you turned your head to see Rarity. She didn’t look mad, quite the opposite in fact. She waved her hoof with a sly smirk on her face, beckoning you to continue.

Rarity trotted over, and laid herself down in front of Applejack. The two mares looked at one another with dreamy eyes, before they slowly drew their lips closer, and entered a sloppy kissing session, their tongues swirling about in each other’s mouths. Applejack moaned due to you still ploughing her from behind. You didn’t slow down at all.

You are also delighted to see that Rarity was a little larger. She must have taken some growth potions to make herself more sexy for you or Applejack you weren’t sure, but you didn’t care right now. Her backside is far larger than normal, almost beach ball-like. At any rate, you will need to give her an anti-growth potion before she grows out of control.

You continued to plough into Applejack’s marehood as she and Rarity continued kissing each other, “I-(Grunt), (Grunt), (Grunt) I’m about to (Grunt) (Grunt) release, you better take (Grunt) (Grunt) it your randy mare (Grunt) (Grunt)!” You shouted in between grunts.

Applejack nodded very fast since she couldn’t give a verbal answer since she was kissing Rarity, as well as moaning in her mouth as well.

Soon you shot your load into Applejack’s marehood as Applejack whinnied loudly as she sprayed her juices out. Both of your juices came to mix with each other. You saw that Applejack passed out from pleasure, making you chuckle, “Well, I guess I win.” You said with a victorious smirk on your face.

Rarity raised an eyebrow confused, “Win what?” She asked.

You turned to her, “Well, miss AJ here, thought I couldn’t make her feel good, so we had a bet. If I won, then I would get to ride on her back for a whole day, while using some less sharper stuff that I’ve been using on Rainbow.” You said as Rarity’s eyes widened with a red face, you noticed that she started dripping.

“But if she won, then we would do cowgirl sex from dawn to dusk with her on top the whole time.” You explained what Applejack would’ve won, but since you won it won’t happen.

Not now it won’t, but it still sounds like a fun idea so maybe next time when you make a bet with Applejack.

You noticed that Rarity’s blush grew even more redder, making you chuckle at her reaction, then you pulled your cock out as Rarity stared at it with lust in her eyes, but then you soon pulled up your pants which you saw made Rarity disappointed, slightly, “If you want my cock Rarity, then you must prove that you can be a good mount.” You said as you stood up with Rarity standing up as well.

“Oh my darling… you’ve gotten huge. Much bigger since last time I saw you when I made you those clothes.”

“Every mare I claim, I just get a little bigger. Getting more and more easy to tame mares. Take Rainbow and Applejack here. You saw Rainbow the other day didn’t you?” You asked with a smirk making Rarity blush as she did remember the look in Rainbow’s eyes, they had nothing but lust in them from when you rode her through the village.

She turned around, then leaned down again and turned her head towards you, “Then please mount my back stud.” Rarity said as she shook her ass making it jiggle.

You smirked as you leaped onto Rarity’s back making her grunt when you landed on her back, then you placed the bitless bridle on her head, before taking the reins in both of your hands, “Hyah! Giddyup!” You ordered as you smacked her ass and kicked her sides with your heels making her whinny in pleasure, before she stood up and galloped away from the unconscious Applejack.

You pondered to yourself, Rarity should be an easy claim. She is already tame for the most part. You just need to mount her from behind. But you also need her to be at her breaking point in order for her to be begging for your massive cock, so you need to push her to her limit and riding on her back and sexually tormmenting her would be the perfect way. She already wants your cock it seems. But she would have to earn it as well.

“Hyah! Hyah! Show me what you got! Show your master that you can keep up! Hyah!” You demanded as you slapped her massive ass each time you shouted ‘Hyah’ as Rarity whinnied in pain and pleasure as she sped up hoping to please you.

You slapped Rarity’s white, fat bubbly ass repeatedly, each time she would slow down, you weren’t having that, you were going to show this mare who’s boss. Her ass is growing more red with heavy slaps you applied with even a small red hand print taking place.

You alternated between slapping each asscheek, you held the reins in one hand, while the other one slapped her ass. Her cheeks jiggled about like a stormy ocean, creating loud meaty slapping sounds of flesh, slapping against flesh. It was a good thing she took an anti-growth potion, because Rarity would be growing out of control by now… not by anger… but in size.

“Woah, my pony woah!” You ordered as you pulled the reins making her slow down before stopping. Once she stopped she was a panting and sweaty mess, you can also feel her sweat on her back, which is making your pants wet, but you didn’t mind that right now since she obeyed your orders without question and she went out of her comfort zone for you.

You patted the side of her neck, “Rarity, turn and look at me.” You said as Rarity turned to you, and made to face you. She stared at you with dreamy eyes. You leaned forward, and kissed her square on her plump, equine lips. You reached a hand around her head, and began to tenderly scratch her ears. You wanted to show you were a gentleman. That you weren’t just a rough brute, that only happens while riding and in the bedroom. You were never rough with Fluttershy… other than sex.

But you wanted to see if Rarity would do anything for your cock, and it seems like she will. So you decided to test one thing out, you got out your whip and spurs, “Now Rarity, if you allow me to use these on you, then will go for some hardcore sex. You want to?” You asked as Rarity stared at them for a minute before nodding with a sexual smile on her face.

“Show me stud that you can tame me, like you did with Rainbow and my beloved.” Rarity said and that was all you needed to hear.

You put the spurs on, while you held the whip in your right hand, then without any warning, “Hyah! Giddy up!” You shouted as you slammed your whip across her ass and tagged her sides with your spurs.

Rarity’s eyes widened as she whinnied in pain and pleasure, but then to your surprise she grew a few inches into the air, but she galloped from her place. You looked back at her backside, abiding by how extra thick it had become.

You reacted fast as you yanked hard on her reins, making her stop as she reared up, pawed the air and whinnied louder than Applejack whinnied, when she came down you patted her neck, “Whoa, girl. You need to top up before you… well, grow out of control.”

Rarity blushed in embarrassment, “Sorry, darling. I must have not taken enough.”

You delivered a hard slap with your whip again, as she grew once more a good few inches, as well as making her whinnied loudly in pleasure. “It’s okay. I love big asses. Just take this.” He placed the bottle to her lips and she drank it down. Subsequently, she soon shrunk back down to her normal size.

Once she finished it you put the empty bottle in your bag, then you grabbed the reins in your right hand again as Rarity turned straight, “Now you randy mare. For that little setback, I’m gonna push you even harder! HYAH! HYAH!” You shouted as you slashed your whip across her ass and tagged her sides with the spurs, more roughly, making her whinny in pain and pleasure again, but much louder than last time as she galloped again.

You rode this already tame horse for an hour since you made her drink the potion. Until she was exhausted. You didn’t have the heart to continue, and you felt she needed tender sex, rather how rough you were with Applejack. Her rump was raw red from your slaps as well as some red welts on her ass from your whip slashing across her asscheeks.

You pulled the reins in to halt your new horse making her slow down before stopping. Right now she is a panting and sweaty mess, you stroked her mane with love and affection making Rarity lean into your touch and whinny softly. As you looked down to her barrel and saw that it was starting to go purple from the spurs that you used on her.

It was ironic you expected Applejack to behave like this and Rarity to behave like how Applejack behaved, but you weren’t complaining.

You gently kissed her forehead, and rubbed her cheek softly. “You've been a good mare. Sorry, I was a cruel rider,” you took out a small glass vial. “Drink this, my sweet thing. You’ll feel better.” You offered the potion to her. She subsequently drank it down in one gulp.

You turned back and saw that her massive ass went back from red to pure white like snow. The welts, disappearing from view within mere seconds as well as the bruises from your spurs on her barrel. You lovingly lay your hand upon her rump, and watched your hand sink deeply into her plush softness like that of soft marshmallow.

“It’s alright darling, I know you were testing me. I’ll admit I’m not as strong as Rainbow or my beloved Applejack, but I knew that if I were going to have your Foal production, then I would need to have earned it.” Rarity replied in lust, you blushed a bit at the term ‘Foal production’

“Rarity, you could have told me to stop at any point. I don’t like seeing my mares hurt too badly. You just took it, like how Rainbow took it.” You replied.

Rarity giggled slightly, “Yes I suppose I did, didn’t I darling? And don’t worry, you can be as rough as you want next time. It was actually hot.”

“The next time I ride you, I’ll be much more gentle. I’ll treat you like Fluttershy. You earned it.”

“Fine, next time be gentle, but the time after that be as rough as you want, since just because I’m a lady doesn’t mean I can’t take it.” Rarity said as she closed her eyes and lifted her head up like rich people do. Her right hoof waved nonchalantly in dismissal, with a smug look on her face.

“I just feel a little guilty about how rough I was with you. You were a good, obedient mare from start to finish. You didn’t deserve that.”

“While that is very sweet of you Anonymous. I can take whatever you deal with. And truth be told, I like it when you dominate me, and it makes me feel so hot.” Rarity admitted with a healthy blush on her face.

“Just tell your friends, if they ever want me to stop being rough with them I will. I don’t like seeing my mares upset. You are very beautiful. Applejack was the most stubborn of our time together today, but I could never imagine myself hurting her and making her cry. She’s a big softy deep down, it would be cruel if I was too rough with her.”

“You sure treat Rainbow in a very cruel looking way darling.” Rarity said with a sly smirk which told you she was playing.

You chuckled slightly, “Rainbow rapidly recovers from any treatment I give her. She has gotten very strong. And she was exhausted for one day after some hardcore riding all day. But after the next day she was back on her feet and ready for me to ride her again. So she can take anything I dish out on her . . . not that I get too rough, since I know to hold back when needed, but with Rainbow, I don’t have to hold back too much.” You replied with a serious tone making Rarity smile and nod her head understanding.

You dismounted as you removed the bridle over her head before putting it in your backpack, then Rarity lowered herself down to sitting on her knees.

You positioned yourself behind Rarity, and laid both of your hands upon her plump rump, your hands sank deeply into her warm, plushy softness. With a hum from her horn, Rarity gently lowered your pants and your cock spung free to slap against her right buttcheek. Teasingly, you rubbed your long, thick cock against her three diamond cutie mark, creating a deep depression upon her cheek with the applied pressure of your cock pushing against it.

Rarity moaned as she felt your cock pushing up and down against her massive bubblebutt making your smirk, “D-darling . . . p-please.”

“Please what?” You asked as your smirk continued to grow.

“Pl-please st-stop te-teasing me.” Rarity replied with a moan as she suddenly grew a few inches again.

You were a little taken aback when Rarity’s rump began to air balloon, and slowly pushed you backward as it inflated in size, ‘The potion should not have worn off that fast!’ You thought to yourself in surprise and shock. You heard the hum of a horn, and Rarity took a glass vial out from your backpack. She took it to her lips, and drank it down. The potions effects immediately took place, and Rarity’s rump returned to normal.

“Oh, sorry, darling. I had no control over it. I hope you’re not mad at me, right?”

In response you gently kissed her rump which earned a happy whinny from her, “Rarity, I love big asses. Sometimes I love to see your ass get really big, it makes it fun to watch it bounce and even funner to slap. I am an ass man, and I like seeing my mares’ butts getting bigger, it is really hot for me. And besides, you get to dominate me for once as your butt gets bigger.”

“Oh, you make me feel so special.”

“You, and all the rest are special to me,” you said softly, as you slowly, and gently pushed your cock into Rarity's lovely marehood. Inch by inch you made your way inside her, the mare moaned softly as you gradually pushed your massive cock inside her. Eventually, you made it to her deepest barrier, and kissed her womb.

However, the mare claiming effect took place. Your cock grew larger inside her, your thick tip pushing against her womb. You had to pull back slightly as your cock became just a little too big for this sweet thing. The lower section of your cock came to be sandwiched between her thick soft asscheeks. Her marehood squeezed down your cock as it became just a little bit thicker. A good 5 inches of your cock was not claimed by her pussy. The mare claiming effect seem to be getting stronger with each mare you claimed. You must be at least 40 inches long now when fully erect.

“Oh, my darling. You gotten even bigger.” Rarity gasped as she felt his cock becoming bigger while inside of her.

“I told you, every mare I claim. I get a little bigger each time. They get more and more easy to tame as well. Do you think it would be okay if I tried to tame Princess Celestia and Princess Luna?”

Rarity giggled, “If with your monstrous cock and by riding them on their backs to exhaustion then, I think yes you can. If you rode them the same as you rode me.” Rarity replied.

Twilight’s voice spoke in your mind. “Yeah, we would be okay with that. Just please, leave my brother’s wife alone. Okay?”

You were slightly surprised when you heard Twilight speaking to you, but you figured that she must’ve heard your thoughts before you asked Rarity. But you nodded at Twilight’s request, “Of course. I would never try to take a married mare away from her husband.”

You really wanted to try your hand at taming the two. They had the biggest asses you've ever seen in this land. Even bigger than Twilight. And they looked to be well fit, so they could be perfect for riding on their backs.

“Ehem. Anon, if there are any other mares you want to ride? Just make sure to ask us, and we may agree to it,” said Rarity breaking you out of your thoughts. You turned back to her and saw she had a sly smirk on her face.

“I think Lyra really likes me. I may need to talk to Bon Bon about it though. I might have a threesome with the two before I get to ride them and a threesome with the princesses, that would be awesome.” You explained before you had a sly smirk on your face as well, “By then… my cock will be even bigger since I would claim Pinkie Pie. So, it should be easy.”

Rarity giggled at that, “Oh, you have such confidence, you devious stud.” Rarity told you.

“Well, it is getting easy. Applejack was not so hard. And she was as stubborn as a mule, and from what I heard about Celestia, Luna, Lyra and Bon-Bon, I think only Bon-Bon will be a bit of trouble, but I should be able to make those other three mine pretty easy.” You replied, making Rarity giggle in response.

“Darling, while I would much like to hear about if you can tame those four, turn your attention back to me, because if you don't mind if I give you a brief blowjob? Just to see how far I can take you?”

“Sure, sweet thing,” You pulled out your member before the prone mare, that is rapidly hardening at the prospect of getting a blowjob. You stroked your member until it was at full mast, before you guided it to Rarity's open mouth. You slowly pushed forward into her, your cock becoming enveloped by the warm, wet softness of her mouth. It pushed down her throat, creating a big bulge in her neck. Inch by inch you pushed your way inside, until you could not go anymore… a good ten inches could not reach down her throat, and you have not even claimed all the mares you wanted yet.

“Big, isn’t it? It’s only going to get bigger with each new mare I claim.”

“Uh, huh,” Rarity could only say, with her mouthful but she nodded telling you her answer. The mare lovingly stroked your member with her large, equine tongue, licking your long, thick, heavy member inside her mouth, and down her neck. She then began to gently jerk her head back and forth, lovingly sucking upon your cock with a wet slurping sound. You moaned softly at the feeling, your hand coming to rest upon her silky soft mane.

“I thought you only wanted a brief blowjob… but I’m not complaining. You’ve been a good mare. You deserve this,” you said softly.

She could only hum around her mouthful in answer. Your cock was stuffed down her throat, so she couldn’t speak clearly. The mare then abruptly pulled back, releasing your member with a loud pop. Your cock was soaked with her saliva and it was dripping.

“Sorry, darling. I really wanted your cock. I can’t wait to see it even bigger.”

You smirked as you walked behind her again, and positioned your massive cock into her rump and without any warning you slammed it into her pussy making her whinny in pleasure at being penetrated by you.

“You’re a good mare, and you need some more loving it seems,” you said, grabbing her massive asscheeks, your hands sinking deeply into her plush softness. “But you better be ready to work again when we’re done.” You added on.

“Yes darling, I’ll work as hard as you want! If you want to ride on my back all day, then I’ll let you! If you want to put a collar on me, then I’ll let you show everypony that I belong to you!” Rarity said with lust in her voice.

“Well I won’t put a collar on you, so I’ll settle for riding you for a day.” You said as you continued to jackhammer your cock into her pussy.

“(Moan) (Moan) (Moan) (Moan), A-Anon (Moan) (Moan) I’m ab - (Moan) about to (Moan) (Moan)!!” Rarity said as she continued to moan loudly.

“(Grunt) (Grunt) Same (Grunt) and you better (Grunt) (Grunt) take every last drop!” You shouted.

“I (Moan) (Moan) I will!”

“RRRAAAAIIITTTTYYYY!!”

“AAAAAANNNNNOOOOONNNN!!”

You and your mare shouted/screamed before you unleashed inside her with a heavy blast of your creamy human spunk. You shot wave, after wave of your thick and creamy cum into her. The anti-growth potion effect seemed to have worn off already as her rump began to air balloon, pushing you backward.

“Sorry, darling!”

“Mmm! It’s okay, my sweet filly.”

Soon once both of you have calmed down from the orgasm you both had, you took out another potion and made her drink the whole thing. Once she drank it all, her rump returned back to its normal size

“The potion seems to wear off quickly,” Rarity said, red faced in embarrassment.

“Well, my cock has got even bigger and stronger after claiming you, so maybe it’s overriding the potion. I think I need to give you a stronger dosage.”

Soon you stood up, then zipped up your pants, before walking over to the bridle, your boots with the spurs and crop, grabbed the tack, put your boots back on, then walked back to Rarity who is still laying on the ground, you reattached the bridle to her head, then remounted your mares back with the reins in your left hand and the crop in your right.

You pulled the reins up and slashed her ass with the crop, “Hyah! Up girl, we need to get back to that disobedient mare!” You ordered as your mare moaned as you striked her ass with the crop as she stood up, your sperm leaking out of her marehood.

Once she was up, you pulled the reins back in the direction you both came from, “Hyah! Giddy up!” You shouted as you tagged her barrel with your spurs and slashed her ass with the crop making her whinny in pleasure and pain before she galloped back.

Once you were back after some hard riding, you saw Applejack asleep with a pleased smile on her face.

The mare stirred, opening her eyes. “There ya are. Ah wonder, how much bigger have you gotten down stairs.”

“Let’s just say, darling. I can’t swallow his entire cock down my throat.”

Applejack blushed at that as she looked up at you with you still sitting on your mare’s back, but then you dismounted, took the bridle off of Rarity, then walked over to Applejack.

“I still wish to claim some more mares. So, I am only going to get bigger and stronger. I might need to give you mares some growth potion to take me to the bottom at some point, without growing further at the same time.”

“But moving on from that, let us not forget that you lost our bet.” You said with a devious smirk as you saw that Applejack paled slightly at mentioning that.

Then suddenly, you leaped and landed on Applejack’s back, and quickly strapped the bridle over her head, “And I’m going to punish you for your attitude earlier and I’m going to work you into the dirt, like the workhorse you are.” You said as you took her stenson and placed it on your head.

You pulled down your pants slightly, whipping out your huge member, which came to poke the back of her neck.

Applejack blushed as she felt the tip of your cock rubbing against her neck as she turned to Rarity, “Honey, can yah please help me?!” Applejack begged only for Rarity to give her a sly smirk.

Rather than ‘help’, Rarity came over, and licked her dripping wet sex, “Mmmm! Neeiigghh! Not that kind of help!” Applejack neighed in surprise before shouting at her marefriend.

Rarity giggled, “Ohh, I know, but you disobeyed master. And so you need to be punished and I think master riding you like he rides Rainbow is the best punishment. I’ll make sure that I clean your pussy when the riding is over, since I have a feeling that, master will make you feel like, putty when he’s done.” Rarity said as she walked away, but not before licking your cock like a lollipop.

You smirked as Applejack paled even more, “You’re right about that good mare, and now it’s time for you, my disobedient mare for some much needed hard riding! HYAH!” You shouted as you slammed your spurs into her barrel making her whinny as she jumped up, making her stand up.

“HYAH! HYAH! Giddy up!” You shouted as you slammed your spurs into her barrel and slashed her ass with the crop making Applejack’s eyes widen in pain, before she neighed in pain and galloped away towards the sunset with your obedient mare Rarity following you.

You smirked as you continued to crop and spur Applejack as you rode into the sunset, “Now this is what I wanted. I feel like a real cowboy now.” You thought to yourself, “Hyah!” You shouted as you slashed her ass again making her whinny in pain as she galloped even faster towards the sunset.

You now had five mares claimed. The next mare you wanted to claim was Pinkie Pie. A cute, silly pony. She’s nice, but a little wild. A strange mare overall. Easily excitable, but not aggressive at the same time. She’s quite jumpy, but not afraid of anything.

You knew that it was going to be slightly hard, but you were confident that you could do it. After all, you tamed both Rainbow and Applejack, two of the toughest mares in Ponyville. So you weren’t too worried.

Between when you tamed Applejack and Rarity a bit has happened. A few days after you rode her into the sunset and rode her into the dirt . . . literally, from all of the sexual torment Rarity put her through and your whip and spurs striking her, her mind became overloaded and she collapsed on the ground.

You had to use Rarity’s magic to carry her back to the barn as you rode on Rarity’s back on the way back. You couldn’t do any fun stuff since Rarity had to focus. Once you arrived back at the barn, Rarity put her marefriend to bed, as Rainbow came back wearing her tack, as you mounted your riding pony and rode back home.

After a few days Applejack had recovered completely, you decided to actually fulfill Applejack’s wish if you lost the bet. You let her ride you from sunrise to sunset. However, the mare became tired, rather than you. You used your strong arms to raise her rump up and help her keep bouncing on you. You enjoyed the sensation of her massive backside bouncing up and down on you for hours on end.

You finished off your long sex session with a tender kiss goodnight. The following morning, Applejack gave you a blowjob to your massive morning wood. Since then Applejack didn’t mind you doing some hard riding on her back and riding her from behind, so long as she gets to ride your cock.

You also spent time with Rarity, you even gave her ideas for some clothes, though you told her the designs were from your world, but she was fine with it. But when you two were alone she showed off her body by wearing sexy clothes for you. She even made some riding tack that looked like they were from your world, you tested all of them to make sure they were comfortable to use on your mare and they were, so now you add all these riding saddles so you gave them to each of your big mares.

You always had a mare on hand to give you a good morning blowjob to start your day. Rarity was mostly the one there to give it.

Your bonds with Rainbow, Twilight and Fluttershy grew as well, you spent most of your days riding Rainbow, improving her stamina, running speed and her strength as well. Since you’re hoping that one day you’ll be able to ride her all the way across the Canterlot Path. A road that connected all the major settlements across all the land. And you want to ride Rainbow all the way without stopping once. You did drift off the main road from time to time, and went into much smaller roads that lead to small towns like that of Ponyville.

But you also made sure that Rainbow can handle all types of terrain, so you rode her as she ran over a road with rocks everywhere, it did hurt her, but she would have to learn how to deal with it. And even then you made her where hoof shoes with rocks in them, which caused a lot of groaning from Rainbow each time she took a step, but you need her to overcome it since one day you may need to ride on her back through similar conditions, so you’re preparing your mount for when or if that happens.

So Rainbow is going to need a lot of training for that to happen, since the road is so long. And you do want to visit Manehatten one day and you want to ride Rainbow all the way there.

You also spent time with Fluttershy, if you weren’t having sex or riding on the back of the sweetest mare in Equestria you were helping her around her cottage when Rainbow was doing something or another, but those days weren’t that common.

With Twilight you mainly studied the different species that lived in Equestria, but you also spent time doing some hard riding her as well, once she shrunk down to Rainbow’s size, since her size is the one your used to the most since you spent pretty much every day riding on that back of her’s.

You surprised all of your mares by how much bigger and stronger your cock became after claiming five mares. Your nights of passion were all the stronger. They wanted you to claim even more mares. They were no longer jealous or possessive of you. You had to be extra gentle with Fluttershy, you even had to allow her to grow a little so she can take your cock.

Today was the day you wanted to try your hand at taming Pinkie Pie and you were going to tame her and make her your final mare. However, as you are riding on her back with only her bridle in her mouth, that doesn’t have a bit, though you are slightly regretting it, since all she was doing was giggling, no matter what you did, no matter how hard you swung your whip across her ass or roughly tagged her sides with your spurs, she only giggled.

“Oh Anony, that tickles,” she said as she giggled at the end, which only made your right eyebrow twitch at that. “I really like you.”

You sighed. You were somewhat thankful that Pinkie Pie was enjoying herself. Though as you turned to look at her ass, you saw that all of the marks you left on her ass healed within seconds. She had a supernatural healing rate. She didn’t look it, but Pinkie Pie was by far the strongest mare of them all. She’s even stronger than Rainbow as well as Applejack, and Rainbow is your personal riding pony that you’ve been riding and training her ass off!

‘How the hell is this mare so strong?!’ came your thoughts But then… you remembered seeing an anvil drop on Pinkie’s head… and she shrugged it off as nothing. She seemed to be a living cartoon character. It was a good thing, Pinkie Pie was a sweet, loving mare. Otherwise, you would be in a world of trouble. If this mare got mad, nothing could stop her it seemed and nothing would be able to save you, not even Celestia or Luna.

“I was going to give you this after I rode you, but I feel as if you need it now,” you said with a bag of candy in your hand. With a quick flash of movement, Pinkie took the bag out of your hand with her hoof. She moved so fast, her hoof was little but a pinkish blur by your perspective.

“Mmm!.... Ooooh!.... Thank you, Anony! Mmmm! You’re really nice,” she said, chewing on the candy.

“And so are you, my silly, giddy, little horsey.” you hoped this would work, Pinkie loved candy. You pulled your right hand back, and delivered a hard slap upon her rear. It was music to your ears when you heard Pinkie utter a deep, throaty moan as she chewed on the candy. In addition, you heard the thunderous clap of her buttcheeks smacking together with a loud, meaty slapping sound.

You leaned down over the mare, and kissed the side of her neck. “Good girl.”

“Hehe! Mmm! Ooooohhhh! I really like you!” she giggled.

You smiled at her. “I like you too, Pinkie Pie, but who said you can stop?” You asked before slamming your spurs into her barrel and surprisingly it made her moan as she reared up, pawed the air with her hooves, before coming back down and galloped down the road again

You were unprepared how fast she was… however. This mare was like Sonic the Hedgehog in terms of speed. You could not take in your surroundings, everything seemed like a blur. “Whoa! Girl! Slow down!” You shouted as you pulled the reins back hard as Pinkie Pie placed a hoof upon your back, holding you in place as she skidded to a halt. The gentle applied forced of her hoof kept you from being sent flying into the air.

You took a few deep breaths to calm down. After a few minutes you patted the side of her neck earning a giggle from her, “You’re smarter than your act. Thanks, Pinkie. At least, you knew that to keep me safe.”

“I would catch you even if it were to happen. I move… really fast. You all seem slow to me.”

You raised an eyebrow, “Even Rainbow?” You asked.

“Not when she’s doing her Sonic Rainboom or when she flies fast.” Pinkie replied.

“I see.”

“Well, unless, I drink an energy drink. Then I move at such speed I can visit other planets within mere seconds across the universe.”

“What? Have you been on other planets?”

“Oh yes, I have alien friends on other planets. Including other humans like yourself, but they aren’t as fun as you are.”

You sweatdropped at her answer, honestly it wouldn’t surprise you if she was speaking the truth, “Okay, let’s move on, silly horsey.” You replied as you jabbed your spurs into her barrel, wanting to change the subject before you completely lost your mind.

Pinkie giggled when your spurs slammed into her barrel, but she happily trotted down the road again.

“I would take you with me. But I'm not sure if you would survive the trip. Your body is not able to take the g-force I can.”

“I said, let’s move on.” You repeated jabbing your spurs into her barrel harder than last time.

She whined sadly. “Okay… Mr. Grumpy Pants.”

You rolled your eyes at her response as she continued to trot down the road.

“I said let’s move on and you didn’t listen to me. So I need to pick up my pace if I want to tame you.” You replied with a smirk and Pinkie looked over her shoulder and giggled, before matching your smirk.

“Hehe! Are you sure I’m not just taming you? Instead of me?” Pinkie wiggled her eyebrows at you.

“You are a cheeky, mare. I like that, but you need to learn who’s in charge here.” You replied as you pulled her reins to make her look straight again so she couldn’t see as you raised your whip in the air.

“You are my friend. I’m sorry if I’m being annoying…” she lowered her head in shame. “I don’t exactly have the best social skills at times. I like to party, hug, cuddles, and have sex.”

“You’re a party horse. Nothing wrong with that. And… Pinkie… don’t change. Don’t let a grumpy pants like me change how spherical you are. I don’t want to destroy what makes you special. I still want you to be a silly horse at the end of this.”

Pinkie smiled at your words, “Thank you Anon, that means everything to me.” Pinkie said in happiness with tears of joy flowing out of her eyes.

“Good now where were we? . . . Ahh yes I remember so . . . HYAH!! Giddyup you silly mare HYAH!!” You shouted as you swung your whip down on her ass and tagged her sides with your spurs making Pinkie giggle in happiness as her tears of joy vanished before she reared up, pawed the air with her hooves, came back down and galloped away, going about the same speed as you ride Rainbow.

“That’s a good girl, you are learning to control your speed,” you said as you gently patted her neck. Pinkie Pie simply made a sound like a dog’s chew toy in happiness. “Keep it up girl!” You shouted as you tagged her barrel again making her giggle in response as she galloped slightly faster.

As silly as Pinkie Pie was, she was by no means dumb. She protected you, her rider to stop you falling and that was a sign of a good mount, a mount who cares about their rider. Since she could move at great speed, even if you were somehow to fall, she would catch you. She was basically Sonic the Hedgehog.

Because when riding the mount must trust their rider at all times and in case their rider can’t see where they’re going it’s up to the mount to bring them to safety.

His belly growled as Pinkie giggled in response. “Are you hungry?” she asked.

“Yes I am and you rider needs some food right now. So take me to Sugarcube Corner for a snack!” You ordered before you slapped her ass, triggering to grow larger, by a good few inches. You took delight in the sound of her hearing fat buttcheeks smack together with a meaty slap from the rich influx of fat pumping into it.

“Hey?! That will only make me even more hungry!” she whined.

“Your master has ordered you to go! You are disobeying me right now! Go!” You ordered again as you slapped her ass again harder this time, making her grow even more and this time she didn’t question it, but galloped towards her shop.

Pinkie had to duck her head through the door because she stood over 10 feet tall now. Two feet taller than she was beforehand. “Hehe! I’m big! I need some of the anti-growth potions later.”

But luckily you packed some, “No need, I carry some with me, just in case something happens. Here, drink up.” You put the bottle up against her mouth as she started to drink it. Once it was finished she shrunk back to her normal size.

You tossed a huge sack of bits on the counter of Sugarcube Corner. “That’s over one thousand bits. You can basically have all you can eat now.”

“Where did you get all that money?” Pinkie asked as she looked over her shoulder at you, since you are still mounted on her back.

“Princess Twilight has been paying me well. My work advances the magic of friendship between a human and a pony.”

“Okey dokey lokey chockie . . . Are you gonna dismount?” Pinkie said with a smile, before asking.

You hummed about it, pretending to think about it, before you shook your head, “No, as your rider, my feet shouldn’t be allowed to touch the ground. It’s a rule with your friends as well, if for any point my feet touch the ground before our time is up, they get a punishment of my choice,” It was wrong, you made that rule not too long ago while riding Rainbow she tripped and fell over, making your feet touch the ground.

She was fine, but you decided that if your feet touch the ground while riding, then they get punished, and you did punish Rainbow a bit rough for letting that happen. So you told your other mares to never let your feet touch the ground while it’s their time together.

“Pinkie, public sex is legal here? Right? Even in this shop?” You asked while looking around her empty shop while still mounted on her back.

“Yep. I have served customers that way in here before.”

“A cake shop and sex shop? Hah!” You said before laughing at the end.

“So Mr. And Mrs. Cake won’t mind if they walk in and see us fucking?”

“Nope. I saw them fucking before myself.” Pinkie shrugged her shoulders before eating some more cake off the counter.

You smirked, “Perfect.” You said, before you stood up in the stirrups, finished some cake you were holding, took off your pants to reveal your fully erect cock, not that Pinkie saw since she’s still eating, you turned around so your ass is facing the front, which gave you a clear view of her massive ass and without any warning, slammed your cock into her ass making her moan loudly in surprise as some cake fell out of her mouth.

Your hands took hold of her fat bubbly asscheeks, sinking deeply like soft pizza dough. Pinkie’s rump was particularly large, you were happy. She has the second largest rump among her friends, apart from Twilight. Her ass is also about the same as Fluttershy since her body is similar to that of a goddess, but it wasn’t time for Fluttershy, it was Pinkie’s turn today.

Pinkie uttered a muffled moan with a mouthful of cake in her mouth. “Mmmm! Oooh! You’re bigger than any stallion I had before.” She said in a muffle voice, but she managed to quickly swallow the cake in her mouth, as your cock twitched inside her, growing even larger, by another 5 inches. “Ooooo! You got even bigger!”

“I just claimed you, my dear. So you are my mare forever! And I mean it, Princess Twilight can make me and all of you immortal,” You said as you started going in and out of your newly claimed mare, “And with that, I’ve claimed all of the Elements of Harmony, now I just have to tame this one and the last of them.” You thought to yourself.

You thrust back and forth against her lovely, fat rump. Her ass jiggled about like jello from the impacts of your hips against her. The mare moaned, and giggled as you fucked her from behind, while you were still mounted on her back, “I definitely need to do this with Rainbow to see how long she can run before she loses herself to pleasure and then see how long until she passes out,” you thought to yourself with a smirk.

“Yes I would love that! Having sex with you anytime, anywhere and anyway forever would be a dream come true for me!” Pinkie shouted as she continued to moan as well.

You don’t know if it was her strength, or not, but you found yourself coming close. The softness, and warmth of her strong marehood was overpowering you, but you can’t release, you have to make her release first or at the same time, otherwise she would take advantage of your release and take control. You can’t allow that to happen, you are in control here and you’ll prove it.

Somehow, you drifted away from the edge of your release. You took a deep breath, stopping momentarily, just to feel her lovely marehood repeatedly squeezing down on your cock as it lay deep inside her.

You then pulled back, and resumed thrusting into her with wild fury, you were determined to make this mare release first. The mare’s legs became shaky, and you can tell that there’s a slight bent in her back, which told you that she’s losing energy. Then suddenly she collapsed to the floor with a loud bang, your cock came slamming deep into her. Pinkie arched her back, and unleashed a loud moan, and you felt her marehood clamp down hard on your cock as she released a huge bucket of her creamy marecum around your massive cock inside her. You fucked her through her orgasm, repeatedly slamming your hips against her as she released wave after wave of cum upon your cock and lap. A flood of her marecum came spilling out of her soaking wet sex.

“PPPPPIIIIINNNNNKKKKKKIIIIIEEEEE!!” You shouted as you finally shot your load into her making her whinny in pleasure as she grew in size quite a lot, before her head fell down and landed on some muffins on the bottom shelf.

Your cock released spurt, after spurt inside her. After a bit you were drained out, as you pulled your cock out of her twitching marehood while breathing heavily, as you watched her ass jiggle with each twitch.

You took your feet out of the stirrups, then made to walk around the mare, and got a potion to her mouth. She drank it without saying a word and you saw her eyes have rolled into the back of her head. You quickly made to stand behind her rump, to watch the show.

You watched Pinkie’s ass rapidly air balloon toward you. You had to walk backward to avoid not being rolled over by her expanding buttcheeks. You could see her cheeks knock over chairs and tables with a loud bang.

“Hehe! You crazy Anon?!”

Just before Pinkie was about to bulldoze down the walls of the shop, her growth came to a stop. Her body then rapidly began to deflate, and shrink back down to normal size.

“What was the point of that? We will need to clean up after,” she asked.
“Sure. I just wanted to show I can be silly too. I’m not all serious. I want you to be my friend.”

Then you sat back on her back with a victorious smirk, “I have tamed all of the Elemental mares! Yee-Haw!” You shouted before raising your fist in the air in victory as Pinkie raised her hoof in the air and giggled.

“So, what now?” she asked.

You thought about it for a bit until an idea came to you, “Oh, I have a good idea.”

“Ahhh can’t believe ahh let yah talk me into this.” Applejack said before whining in pain as you slashed her ass with your crop.

“Stop complaining. We’re about to start.” You said as you shoved the bit into her mouth, then rode her to the starting line.

You are going to have a race, a horse race to see who is the fastest mare, but the thing is, you are not only riding Applejack, you are riding all of the mares you’ve tamed. Twilight created temporary magic clones so this could be possible, so all of your mares will have yourself riding them and pushing them to their limits. Princess Twilight's magical strength was amplified dramatically, She far outpaced even Princess Celestia, Princess Luna, and Princess Cadence. If she wanted to, Twilight could take them all on at once, and win.

The original one of you is riding on Rainbow since she is your riding horse and it didn’t feel right to have a clone ride her. Even Twilight is going to be racing as she is the same size she used to be.

You created a race track that is the same size as a normal horse track back in your world, and it was possible thanks to Twilight using her magic. All of your mares wore riding saddle, with bridles and bits in their mouths, since this is a race not sex time though one day they’ll do that. All of you wore different colour clothes and carried whips in your hands, even the one riding Fluttershy since she wants to prove she can be just as good as her friends.

“Alright racer!” Another version of you shouted as he raised a flag in the air as you, your clones and mares got ready, “On your marks . . . Get set . . . GO!” Your clone shouted before the sounds of whips flew throughout the area and muffled whinnies as well before your mares galloped.

“This is the best day of my life!” The real you shouted as you whipped Rainbow’s ass getting her to speed up as she took first place.

You and your clones gave it to your mares, getting them to speed, but the clone riding Fluttershy was more gentle than the others. Somehow Pinkie Pie was in last place, but you knew she was much faster than anyone, even Rainbow Dash. You saw your clone was unleashing a bragge of crops from the crop, but she is merely giggling and racing at a trotting pace.

You merely shrugged, slightly glad that you weren’t riding her, though you had a feeling, if you were riding Pinkie, she would win in a heartbeat. You could hear your mount’s thoughts on the matter through her mind. “Is Pinkie losing on purpose?”

“Yes. Stay focused!” You shouted through your thoughts as you slashed her ass with the crop again making her whinny in pain, but sped up as ordered.

It was a close race between Rainbow and Applejack, but you gave Rainbow that extra spurring and cropping to get her to cross the line first. Once Rainbow and Applejack crossed the line, they were panting as they stopped.

You and your clone stared at your mounts, “I didn’t tell them to stop, well, they’ll be getting a punishment later on.” You thought to yourself as soon the others came over the line, before stopping as they all lined up with Rainbow and Applejack.

Pinkie came last, her rider, very unhappy, glaring down at his mount. “Pinkie, you’re the fastest! What the hell?!”

She simply giggled. And he sighed, “I give up. You defeated me, Pinkie.”

You stared at your clone and Pinkie, “I’ll punish her later.” You thought to yourself. “At least… I’ll try to.”

Rainbow turned toward the horizon and trotted toward the sunset, the other five mares following.

Soon they were lined up as they turned to each other, nodded, before turning to their riders making you and your clones smirk in response.

“HYAH!! GIDDYUP!!” You and your clones shouted at the same time as you all slammed your whips into their asses and tagged their barrels with your spurs, making them whinny in pain and pleasure, before they all galloped side-by-side into the sunset.
