Taming

You were told to stay at the library. But you could not stay. Your new cute little horsey friends needed you. You weren’t going to be a coward and let them face Nightmare Moon alone. You were going to take action, and maybe even save Equestria. You set about putting on some badass cowboy gear with black cowboy boots with spurs on the heel of each boot. You were ready to try to tame the wicked mare Nightmare Moon. Instead of a pistol in your holsters on your hips, you put a carrot in each one. You also got a bridle with a bit and reins so you can control her and a riding crop just in case something bad would happen. This would be useful if you needed to discipline her.

You were the first human that somehow ended up in Equestria, you’ve been living in Ponyville, in your own house, it was nice, it has a large paddock, and you worked on Applejack’s farm.

All of the ponies were only about 4 feet high, so you couldn’t ride on any of them. However, you were more than willing to ride these ponies from behind, they still had lovely, plump asses. They were intelligent and far cleaner unlike the ones back home.

However, riding on top of one of them would just mean your feet would end up touching the ground. Nonetheless, Fluttershy really enjoyed you being on her back, despite the fact that she wasn’t able to move, which was a shame since Fluttershy wanted to, but it just resulted in your feet getting dragged across the ground which was unpleasant, and Fluttershy was only able to move a few steps since she wasn’t a workhorse.

Despite that you remembered fondly petting her, kissing her neck, and scratching her ears, you were even able to give her ass a few smacks, with her permission of course. She turned her head to face you at some point, and you kissed her while on her back. You got lucky with the cute pony and rode her lovely plump backside from behind. Your cock seemed to have no issue pleasing her, despite the fact ponies had much larger penises than you. She was also a virgin, so that helped a lot.

When you saw Nightmare Moon who was about the size of a shire horse, (if not even bigger in some ways) you knew that you wanted her to be your riding horse, your means of transport in this world.

You were told to stay at home until they returned, but you had a bad feeling that something had happened to them, so that’s why you’re getting ready. To help them and to make Nightmare Moon your riding pony.

All you had to do was tame her, hop on her back and make her yours. You heard Luna was deep down still inside her. You held onto the hope you could bring her back. You will need to be extra careful around this particular big horsey.

You walked through the Everfree forest and towards The Castle of the Two Sisters. When you came to enter the throne room you were shocked at the sight of seeing your six friends huddled together as they lay petrified in stone. A look of terror was frozen on their faces.

The giant mare that is Nightmare Moon stood over them. She stood at least 8 feet tall, or so. She was like that of a draft horse, but on steroids. Her massive rump was well fortified, each cheek of her ass was like that of an exercise ball.

You had no fear. All you needed were your carrots. When you first made contact with ponies, they were not so welcoming to you.

Nightmare Moon narrowed her eyes at you, “And who are thou?” Nightmare flared her wings out as her mane blew behind her like it was alive. She trotted toward you, glaring at you angrily.

You narrowed your eyes slightly, as you simply pulled out a carrot each from your holsters on your hips. The mare’s eyes lit up in surprise at this. All of the aggression left her face. “A gift? Thou is very thoughtful.”

She took the carrots from both of your hands and ate them quickly, once she consumed them, you started to scratch her mane, her eyes widened slightly, but she soon leaned into your touch and whinnied softly. Her mane felt soft and a little cool. Your hand could feel a tingling sensation as the stars in her mane twinkled.

“Ohhh, yeah, yeah right thereeee.” Nightmare said happily as you moved your hand to scratch the right spot.

You withdrew your hand, earning a groan from her, but she turned to you, “So what does thou want from We?” Nightmare asked.

“I just want to get to know you.” You answered.

Nightmare looked at you in suspicion, “Why would thou want to know We? Are thou hoping that thou will be able to free Luna from our grasp?” Nightmare asked.

“I think you are misunderstood. You are not as evil as they say, because you could’ve crushed me at any moment if you wanted to, but you’re talking to me instead..” You replied as you started rubbing her neck.

“W… we…. will treat thou far better than the rest when we take over this world if thou will keep these charming words up, as well as thy rubs and scratches. We sense-desire in thy eyes. What do thou ask of us? Ask away, as long as it is appropriate.”

“Well, as a human. I don’t move very fast. I want a pony to help get me around but since they are too small for me. “Can I mount you on your back and ride you?” You asked.

“W… We suppose thou can.” Nightmare replied.

You smiled as you walked to her side, placed your hand on her back, before jumping up, then swinging over her, and then you settled down upon her back. You heard her grunting slightly from the impact, but she was able to stay upright and you made sure that your legs wouldn’t hurt her wings, which you knew thanks to Fluttershy that a pegasus’s wings were sensitive.

You sighed in bliss, her fur is cool, but not cold, but it’s also very soft to feel. You rubbed your hands up and down her neck feeling her fur's softness.

Nightmare turned her head and looked at you with a smirk, “Thou appears to be enjoying yourself up there, We see.”

You smirked back, “Yes I am, I’m finally able to ride a pony that can move and the fact that your fur is so soft makes it even better.” You replied.

Nightmare blushed slightly at your words, but she shook her head slightly as she continued to look at you, “Thou hast done this before?”

“Yes, but they weren’t able to move, since they’re too small and it causes my feet to touch the ground. Even if they were tall enough, poor Fluttershy was not strong enough to carry me around. The poor mare started to cry since she thought that she disappointed me. I cheered her up, by mounting her from behind instead.”

Nightmare Moon blushed heavily at that as she turned to the front. You smirked as you got out your bridle, and quickly slipped it over her head, making her gasp in surprise, which allowed you to gently slip the bit into her mouth, which tingled her taste buds due to the fact that its metal.

“Whh . . . what is this?! Why did thou put this thing on us?!” Nightmare Moon shouted as she communicated through her mind and turned to you again.

You merely smiled at her, but you were slightly concerned on the inside since she can buck you off whenever she wanted, “Well, you see, when you have a rider mounted, I need to take control, and for that, I need to steer you and I don’t want to pull your mane since it’s so beautiful.” Nightmare blushed at your praise, “So I’ll be using reins to steer you instead, which will allow me to steer you wherever I want you to go.” You explained with a smile on your face.

Nightmare grumbled something which was muffled due to the bit in her mouth, “Fine.” Nightmare thought spoke through her mind.

You smirked, “Great, now with one of the hard parts out of the way, here comes the next part, which should be slightly easier. All you have to do is praise and pat her everytime she follows my orders and if she disobeys well . . . I’ll put a bit more force so that she’ll do it, because I still have to tame her.” You thought to yourself.

You and Nightmare did nothing with her standing there with you on her back, after a couple of minutes she turned to you, “Well, what now?” Nightmare asked.

“Patience, it’s not every day that I get to ride an alicorn, so I want to savor it.” You explained, “Well, if everything goes right, then it will most likely happen every day starting from tomorrow.” You thought to yourself.

“Be forewarned human, we can easily kill thou at any point. Thee is far weaker than us. Thou is at our mercy. So, thou better be a gentlestallion. Thou is only on our back because we like thee.”

You did not show it, but you were sweating on the inside, but you had to be brave and not let her see you sweat, “That may be true, but if you kill me, then who would give you any more ear scratches, head pats, and sweet words?” You asked.

“Hmmmmm . . . That is true. Thy amazing hands feel like no other.”

You reached down and began to pet her starry mane with your left hand. The mare uttered a happy whinny at the feeling. “Mmmm, yes,” she moaned. You smiled, and placed your right hand at the back of her ear, and began to tenderly scratch it.

Her tongue lolled out of her mouth. You could hear a dripping sound coming from behind you. You turned your head around to look at her backside, and you saw her juices dripping directly below her pussy and landing on the floor. You smirked at this as you glanced back to Nightmare and continued pleasuring her.

With a flash from her horn, she took off her helmet, and let her starry mane fully free from the confines of the helmet. It took your breath away.

“We let our mane down for thee,” she said softly, looking back at you with a blush upon her cheeks.

“Yeah, and it looks beautiful, it looks like I’m staring at the night sky up close.”

Once you were done, you took both hands on the reins, “Alright then, let’s go, hyah!” you shouted, slamming your right hand down hard on her buttcheek and jabbing your spurs into her barrels. Her thick, bubbly cheek smacked the other one with a loud, meaty slapping sound of flesh, slapping against flesh.

Nightmare moaned at your actions against her as she leaped over the stonified main six and galloped out of the room. Carefree, Nightmare Moon trotted through the forest, every living thing kept its distance from her.

Nightmare Moon could feel her pool of magic, somehow increasing with the human on top of her. She felt stronger than ever. “If I had this human by my side back then, then I would have been able to defeat my so-called sister.” Nightmare thought to herself.

If she didn’t know any better.. She swore she was a few inches taller. Not to mention, her hindquarters felt thicker and heavier, but she shook it off as nothing.

You looked around as you reined her to the right, making her obey you like an obedient pony, “Good girl.” You cooed as you scratched her ear again earning a whinny of happiness from her.

Every time Nightmare Moon obeyed you with it either going in a direction you wanted, going faster or slower, and sometimes making her rear up for fun, you praised her and either scratched her ear or rubbed her neck.

As you rode around on Nightmare’s back you saw a huge tree root out of the ground and it gave you an idea, “Think you can jump over that girl?” You asked as you pulled the reins towards the root making your mount turn to it.

She snorted, exhaling air out of her nose, looking slightly offended at your question, “Of course we can!” Nightmare answered as she turned to the root.

“Then prove it! Hyah!” You shouted as you slapped her ass again (causing a meaty slapping sound) and jabbed her spurs into her barrel, which made her whinny as she galloped towards the root.

You felt the wind blowing against your face as Nightmare Moon galloped towards the root, once she was close enough, she bent down slightly and pushed herself upwards and leapt over the root.

When she landed, you bounced up and down from when she landed and she continued to gallop away. You pulled the reins slowing her down until she stopped, “Good girl, good girl. I knew you could do it. Something like that was easy for you, wasn't it girl?” You praised her as you scratched her ear earning a slight snort in response, before a happy whinny.

Nightmare Moon could feel her body flowing with newfound power from his loving hands. She swore she felt yet taller, and her rump even thicker by a good few inches.

“Alright then, let’s continue. (Click) (Click) (Click)” You made a clicking sound three times as you tapped her barrel with your spurs as you withdrew your hand away and grabbed the reins.

Nightmare Moon whined sadly as she started trotting down the forest path. “Please, can thou scratch and pet our ears some more? Thy love makes us feel stronger.”

“Now now, Nightmare Moon. I will only reward you with love only if you keep being a good girl.”

“Are we a good girl?” she asked in a worried tone.

You smiled, “Yes you’re being a very good girl so far, so don’t be a bad girl when you’re doing so well so far.” You reply, making her nod in response as she continues trotting down the forest path.

As Nightmare Moon continued to trot down the path with you sitting comfortably on her back, she suddenly came to stop and groaned. “My horseshoes… feel tight. Do you mind if I teleport them off?” She asked as you looked down at her horseshoes. If you didn’t know any better, her legs seemed thicker than before you mounted her.

“Very well, but be quick about it.” You replied as her horn glowed and her horseshoes vanished earning a sigh in relief which was muffled due to the bit still in her mouth.

Once she was done, “Also in the future only I can tell you that you can stop when I pull the reins, then you can stop, otherwise you must keep going.” You told her.

“We . . . we are sorry.” Nightmare apologized but you smiled as you rubbed her neck making her sigh as you ran your fingers through her soft fur.

“I forgive you, since this is your first time with a rider mounted, and I forgot to tell you the rules about being a mount, so that’s my fault on that end, I’m telling you now, so that way you’ll remember.” You explained making Nightmare nod her head in response.

“You know Nightmare, I just thought of a way that you can be a great girl.” You said making her turn to you.

“How?! Tell us and we’ll make it happen if we can get more ear scratches!” Nightmare shouted.

“Well, for one, is Nightmare Moon your real name, or what?” You asked.

“W . . . We do not have a name. We have never had a name before we took over Luna.”

“Well, I think it’s time for you to have a name since Nightmare isn't great and I think calling you Nightmare every time gets dull pretty fast, so a new name is needed,” you said, making Nightmare nod in response to that.

“So what shall be our name?”

You released your grasp on the reins, crossed your hands, and closed your eyes trying to think of a name that matches Nightmare’s current form, “Mmmmmmmm . . . mmmmm how about . . . Lilith?” You suggested.

“Lilith?” She repeated.

“Yeah, I think it’s perfect for you, what do you think?” You asked.

“Lilith . . . Lilith . . . yes we like it. From now on, our name will be Lilith.” The newly named Lilith accepted her name.

“Ok, I’m glad that you like your name.” You told Lilith, making her nod in response.

“Yes we do as well, was that all you wanted so that I can be a good girl?” Lilith asked.

“That and there’s something else.” You said, making Lilith nod in response as she continued to listen, “Well, I always wanted to fly, but poor Fluttershy couldn’t carry me, so she couldn’t fly. But you are carrying me with ease. So I want you to fly in the air.” You answered making Lilith nod in response.

“It will be very dangerous up there. I will need to cast some spells to keep you safe.”

“Very well, after all, if you let your rider fall, you’ll be a very bad girl. And I doubt you want that, do you?” You asked, earning an immediate shake from her head saying no.

“We shall cast feather falling, cold resistance, and a bound spell, that will prevent thou from falling off our back. Even if thou were to somehow fall, feather falling will make thou only fall slowly.” Lilith lit up her horn with magic and cast these three spells on you.

You made to test if the bound spell worked… you attempted to lift yourself up… but, it seemed you were stuck to her like super glue. You could hardly move. A powerful tug of force was holding you in place.

You raised your eyebrow slightly at the fact that she cast a spell to prevent you from falling fast and a spell that makes you bound to her back, “Is feather falling needed? I am now stuck on your back,” you asked.

“We are not willing to take any chances. We have grown to like thou with thy words and pets.” Lilith answered. Her words were quite literal, she had indeed grown, but you and her didn’t see that.

You shrugged your shoulders slightly, “Fair.” Lilith turned straight and waited for your orders, “Well, are you ready?” You asked.

“Of course we are,” Lilith answered as she extended her wings outwards.

That’s when you got the idea, “Actually before we do.” You said as you gently stroked her wings making her moan slightly as you ran your hands through her wings, “Wow these are even softer than Fluttershy’s wings.” You said.

“Ahhh . . . Of . . . of course they are. Our wings are much better than any normal pegasus.” Lilith replied, but it earned her a hard slap on her ass from your crop that you took out of your pocket and made her whinny in pain.

She turned her head and saw the look of your disapproval, making her shrink slightly, “Don’t insult Fluttershy. She’s very sweet, kind, and caring. Don’t be a bad girl, when you are doing so great so far, but if you continue being bad, you’ll get a lot more whacks.” You said in a dominating and angry tone as you showed her your riding crop.

Lilith bowed her head slightly, “For-forgive us.” Lilith pleaded in a low voice.

You gently scratched her ear, “I forgive you this time, but next time, speak badly about Fluttershy or any of my friends and I’ll have to punish you.” You told her, making her nod her head in response as you put the crop back into your pocket. “Good.” You resumed patting her wings.

Lilith moaned in delight as her wings seemed to extend out even further… and she seemed even taller. You heard her buttcheeks smack against the other from behind. With no further ado, you grabbed the reins again and you jabbed the spurs into her barrel, making her whinny in response before she sprinted forward, flapped her wings, and took off into the air.

You could feel a rush of wind blasting your face as she rose higher and higher into the air. Just before reaching the clouds, the mare suddenly dove downward and swooped over the forest below. Just when she was about to hit a tree, she pulled upward and did a horizontal flip in mid-air. Under normal circumstances, you would have fallen, but you were magically glued to her back with her spell.

The mare surged back high into the air, into the clouds above. Up here, you could clearly see the moon. The moon seemed somehow even larger, and there seemed to be even more stars in the night sky.

“Our night is even more beautiful thanks to thou,” she said, looking back at you with dreamy eyes.

You placed your right hand on her cheek, causing her to blush profusely. From there, you lovingly stroked her cheek. The mare sighed happily from your tender touch. Her body swelled larger again, the moon in the sky grew larger, and more stars spawned into existence. Your hand slipped away from her cheek as her head rose higher into the air, you made do by simply stroking her mane instead.

Her riding gear seemed to grow as well, under normal circumstances her swelling body would shatter it. From your love, Lilith grew and grew… until she was about 16 feet tall, she was nearly as tall as a giraffe. Despite the fact that she was about the size of an african elephant at the very least, she was still able to fly in the air without issue.

The giantess mare looked back at her own backside with pride. It was larger than ever before. Even Princess Celestia could not hold a candle to it. She watched with tears in her eyes as her rump swelled bigger and bigger from behind her, like an inflating balloon. No stallion had a large enough penis to please her now, without her giving them magical help.

The mare sighed sadly when you abruptly pulled your hand away from her mane. “Huh? Why has thou stopped feeding us thy love? Have we become too big for thee? We can make ourselves smaller if need be.”

“Not yet, Lilith. I like you being big and sexy.” Your loving words triggered her to have yet another growth spurt as she gained several more inches in height.

“In that case, Anon, we wish for thou to mount us from behind. Thou is making us stronger with thy love for us. We want to feel thy empowering love raw inside us. We shall magically enhance your stallionhood to mount us properly.”

You were about to say no… (you wanted to fly around in the sky with her some more) but then you thought that this was a golden opportunity to put an end to Lilith’s evil ways. You felt as if you were on thin ice, that if you were to reject her Lilith would become angry and you would fail in your quest to save Equestria. You were indeed making Lilith bigger and stronger. However, rather than corrupt her, your love for Lilith seemed to soften her harsh nature. If you were to make love to her, you could free Luna at long last.

Lilith sensed your hesitation, her eyes narrowed at you angrily. However, her anger vanished instantly when she heard you say. “I would be honored, my beautiful princess.”

The dark mare smiled broadly, showing off her sharp canine teeth, before she flew down at great speed, and dropped down hard upon the ground, leaving a deep crater in the earth from the heavy impact of her hooves. The sheer force caused many nearby trees to fall over, and she created a cloud of dust.

“Whoa, girl!” you shouted as you pulled the reins making her rear up, pawed the air with her hooves, and whinnied loudly. When she came back down she turned to you with a look of lust on her face.

“Please, dismount, and then mount us from behind.” she pleaded.

“Uh, I will need a little help with that,” you did indeed need help, the mare was far taller than before. When you first met her she was about 8 feet tall, the mare was now 16 feet. She had basically doubled in size. She is on par with being like that of an elephant in terms of body mass.

“Not to worry, we shall help thou,” she said softly, her horn glowing with magic. The magic lifted you into the air, and gently placed you down at her behind. Your breath was taken away by the sheer beauty of her massive buttcheeks. She was so tall, you would not be able to reach them without her laying down. Nonetheless, you reached upward and placed your hands on her thighs, her thick, muscular thighs.

You could feel the strength of her powerful muscles. The mare was bigger and stronger than ever before. You were at her mercy now. One buck from her, and it would be over. However, Lilith was happy to feel your hands lovingly stroking her thighs. Her fur felt soft between your fingers.

“Ahh . . . yes . . . thy hands are amazing!” Lilith moaned out as your hands continued to stroke her powerful thighs.

You smirked at that, “Yeah, well when you live with a pegasus ever since you came to Equestria, you know where to touch all of the right spots.” You replied.

“We cannot wait to show off our much larger rump to Princess Celestia. We shall be more lenient toward her when we find her.”

“That’s good, Lili. I knew, deep down you weren't evil.” You said as you took the bit and bridle off her mouth, making her open and close her mouth a few times.

The mare gained several more inches into the air. “Thy words have moved us. Being good… feels good. I feel stronger than ever. I may perhaps even end the whole eternal night. We may just make the night last longer instead.” Lilith said.

Secretly, in your mind. You found Lilith too big. But you dared not voice it. You wanted to keep in her good graces.

The mare lay down on the ground, before you, and spread her cheeks wide, revealing her soaking wet marehood. “Mount us, please,” she begged.

You smirked as you grasped her buttcheeks tightly making her moan, “You can’t demand anything from me, you are being a bad girl right now.” You decided to take a chance. The sheer width of her flanks was so great, you could barely reach her cutie marks on either side of her cheeks. Her ass was so large, you could not fully wrap your arms around it. Your hands sank into the plush, warm softness of her rear, creating a deep depression on her smooth asscheeks.

“We . . . we are sorry, we just wanted to feel thy love for us,” Lilith replied.

“And I understand, but you need to understand that a good mount always lets her rider take control. Which means that I get to pleasure you however I want, and when I’m pleasuring you like this, you must call me milord or master, understand?” You asked in a dominant tone with a smirk, but deep inside, you were terrified. But you were willing to test the waters with her nonetheless.

Lilith was getting wetter when she heard your dominating tone due to the fact that she was leaking even more, you saw her nodding her head in response, “Y-yes . . . we understand milord, forgive us.” Lilith said in a submissive tone making your smirk grow even more at how she has fallen for you so hard.

The mare whined, pleading for your love. She looked back at you with tears in her eyes. You had to act now. Teasing her some more could make her upset.

You pulled your right hand away from her cheek. You watched in delight as the depression your hand left faded away, and her buttcheek resumed a perfectly smooth shape from your hand’s absence. The mare whined sadly from your loving hand no longer touching her buttcheek.

“Wh . . . why did you-”

You cut her off, by shoving your hand between her thick asscheeks, and into her marehood making her whinny loudly in pleasure. Her marehood clamped down hard on your hand, grinding down to a halt. You grunted in pain from the sheer force of her powerful marehood clamping down hard on your hand.

You soldiered on, and pressed forward, slowly and steadily with your arm pushing into her marehood. Her tight, squeezing marehood made the journey very slow. The tight walls of her marehood were clamping down hard upon your arm, to the point it felt slightly painful.

Eventually… you managed to fit your entire arm into her. The mare whined sadly when you finally bottomed out deep inside her. Your head was pressed against her ass, you were that deep inside her.

You flexed your fingers inside her pussy, lovingly stroking the warm, wet, soft flesh of her marehood clamping down hard on your hand, and arm. If this mare could take your arm inside her, you are going to need one hell of a big dick to please her.

Slowly, you began to withdraw your arm, making Lilith whine sadly. To make her happy, you lovingly stroked her left buttcheek with your left, free hand. The warm, bubbly softness of her ass felt incredible for you to massage.

Your jaw dropped once more as Lilith swelled even larger again by several more inches into the air. The new migration of fat added to her buttcheeks caused them to jiggle wildly about like a stormy ocean, and her buttcheeks came to slap against each other with loud, meaty slapping sounds of flesh slapping against flesh.

Eventually, you pulled your arm out of her marehood. It was soaking wet with her juices. You gave your hand a lick, drinking up her creamy marecum. You moaned at the sweet, fruity taste of her creamy juices.

Lilith made a pleading, whimpering sound. Without a word, you answered the call to please her. No more witty comebacks, just love for this beautiful mare. You leaned your hand down between her buttcheeks and began to lick the side of her plump marehood. Lilith cried out a loud horsey whinny in response, her asscheeks came to tightly squeeze your head between them. Her voice was muffled for you as your head rested against her marehood between her thick asscheeks. Your entire head was engulfed between the queen bed mattress-like thicknesses of the canyon gap between her asscheeks.

Hungrily, you ate her out. You lovingly licked her plump sex. You ran your tongue in a circle over the plump lips of her labia. Your face was bombarded with wave, after wave of her creamy marecum flowing over your face like a gentle river. She was absolutely delicious, her creamy nectar was flowing into your mouth. You could hear Lilith crying out in pure bliss, and making a series of happy horsey sounds.

You pulled your head away to look at your handy work. The mare whined sadly from your loving mouth’s absence. Her marehood flowed more cum than ever out of her, the ground beneath you was drenched in a thick pool of her creamy marecum.

You placed your hands on your hips, and pulled down your pants, and revealed your cock out in the cool air. The heat coming off Lilith’s body was like that of a sauna. You pressed your cock between her mattress like asscheeks. However, the sheer thickness of her backside’s canyon between her buttcheeks meant you had nowhere near the length to reach her sex. The gap between her cheeks was like that of a mattress.

Your cock became wrapped in an azure glow, and it subsequently began to grow in size. You placed your hands on the huge mare’s buttcheeks, they sank deeply into the plush softness of her rear. You sighed in pure bliss as your growing cock snaked its way between her thick asscheeks. The mare sandwiched your growing cock between her cheeks, smothering it with their wonderful, heavy, warm softness.

You moaned aloud as your cock came to plunge into her marehood. Her marehood squeezed down hard upon your invader, at the same time her huge asscheeks did the same upon the part of your cock that was not inside her. Her buttcheeks almost felt like a secondary marehood lovingly clamping down on your cock.

Inch by inch, your cock came to push its way inside her loving marehood, until eventually. Your cock bottomed out, deep inside her. The dark mare moaned aloud as your heavy tip came to kiss her deepest barrier.

You basked at the wonderful feeling of having your cock deep inside your mare. Both her marehood and her asscheeks were squeezing down on your cock. You gave her buttcheeks a tender rub with both of your hands before you began to subsequently gently rock your hips back and forth against her. This came accompanied by a loud meaty slapping sound of flesh slapping against flesh as your balls smacked against her lovely ass. A jiggling rippling effect cascaded across her cheeks like a stone being thrown into a lake.

Plat, plat, plat came your hips slapping against her lovely backside. The mare uttered a series of wild horsey sounds and moans as you passionately made love to her. You roamed your hands over her bubbly rear, feeling up her plush softness.

“Neigh for me Lilith! (Grunt) I want to hear your neigh, (Grunt) when I shoot my load into you, do you understand?!” You shouted in between grunts.

“(Moan) Ye-yes we und-understand!” Lilith replied which earned her a hard slap on her bubblebutt making her whinny in pain and pleasure.

Her butt jiggled about like jello, creating a lovely meaty slapping sound as her buttcheeks smacked one another. Not only that, but your slap upon her rear seemed to trigger her to have a small growth spurt. She gained several more inches in height, which caused her backside to smack against your hips. You slapped her ass again, and watched in delight, as it once more grew in size by several more inches. Her asscheeks made a thunderous, meaty clapping sound as they smacked one another.

You were tempted to slap the holy hell out of her ass and watch it get bigger and bigger with each slap, but you stopped yourself. You settled with merely roaming your hands over the wide expanse of her bubbly cheeks. At least as far as you could reach, your arms were nowhere near long enough to wrap around her huge rump. Your hands sank like soft dough into the plush softness of her rump.

Lilith whined sadly when you stopped slapping her butt. “We want more! We are a naughty mare! Slap us some more! Give us more growth!” she shouted.

“How (Grunt) dare make (Grunt) demands from me?! I am your master!” You shouted back.

“(Moan) (Moan) (Moan) For-forgive us ma-master (Moan), your amazing (Moan) cock is (Moan) (Moan) is so amazing that we (Moan) (Moan) forgot!” Lilith replied.

You saw right there and then that now was the moment to move in for the kill, “I’ll forgive (Grunt) you if you offer yourself (Grunt) to me body and soul!” You shouted though you were scared that she might reject you.

“(Moan) (Moan) (Moan)Y-yes, we offer ourselves to (Moan) you master! We’ll be your (Moan) slave for eternity, we’ll carry you (Moan) (Moan) wherever you want, just show us (Moan) (Moan) love forever and we won’t (Moan) (Moan) question your orders!” Lilith shouted, making you smirk in victory.

“Good then. (Grunt) (Grunt) In that case, I think you deserve (Grunt) a reward and you better take (Grunt) every last drop otherwise, there will be (Grunt) consequences!”

“We (Moan) understand (Moan) (Moan)master!”

You began moving even faster, jackhammering your cock into Lilith marehood earning loud moans and horse sounds from her. Your hips smacked against her ass with loud, meaty slapping sounds. Each and every time your hips came to smack against her, it created a wonderful rippling effect like that of a stone being thrown into a lake across her buttcheeks. The jiggling of her ass was more intense than ever at her increased size.

“M-master (Moan) (Moan) I-I’m close!”

“M-me too! (Grunt) (Grunt) So, you . . . you better take (Grunt) (Grunt) everything in!” You shouted as you felt you reaching your peak, “LLLLLIIIILLLLLIIIITTTTTHHHHH!!” You shouted as you shot your heavy load into her marehood.

“NEEEEEEIIIIGGGGHHHH!” Lilith neighed so loudly that it scared the birds away. Through her orgasm, she became even larger. Your cock inside also grew as well, to maintain being inside her rapidly inflating rear.

Her powerful marehood tightly squeezed down on your cock as she subsequently unleashed a monsoon of creamy marecum upon you, soaking you with her creamy essence. Through her release, her air ballooning buttcheeks slowly pushed you backward, the sight of her ass getting bigger and bigger before you drove you onward to fuck her through your own release. You repeatedly thrust your hips against her, taking in the delightful meaty slapping sound each time you bottomed out against her.

With each passing second your steed was getting bigger and stronger from your love. Her huge asscheeks jiggled about like a stormy ocean as new layers of fat were pumped into her ass. This created wonderful meaty slapping sounds as her buttcheeks smacked together during her growth.

Soon, her expanding flanks began to push against two trees from either side of her. The soft fat of her ass was compressed deeply back as they pressed against the trees from under their applied pressure. The trees managed to hold their ground for a short while before her flanks knocked them over, and her buttcheeks rolled over them and shattered them into sawdust from their tremendous weight.

Her growth came to a stop with the last spurt of your seed pumping into her loving marehood. Her rump was now so large, it was practically a bouncy castle. You could not even see Lilith’s head anymore. Your entire vision was dominated by her enormous ass looming over you.

Lilith giggled. “Hehe. We do believe our rump has gotten too big.”

Lilith flashed her horn, and in one fell swoop she reversed her growth. She was back to the same size before any growth enhancements you gave her. She was back to being 8 feet tall, or so. Her size was like that of a draft horse, but on steroids. Her massive rump was still quite substantial, each cheek of her ass was like that of an exercise ball. Your still hard cock inside her was adjusted to a more reasonable size since she was far smaller than before.

“Thy love for us was making our growth get out of control. We hope thou is not mad at us?” she said softly, looking back at you with a look of worry in her eyes. “We can always grow big again from thy love if thou wishes.”

“I’m not angry Lilith. If I ever need to get around more quickly across this land, all I have to do is shower you with love and watch as you, my steed gets bigger and bigger until you reach the size I want.”

You lovingly stroked her crescent moon cutie marks with both of your hands upon her rump. “Plus, I would be lying if I said I didn’t like seeing your ass getting bigger.”

Lilith smiled back at you with a blush upon her cheeks. Your loving words triggered her to have a huge growth spurt. You sighed in pure bliss watching her ass slowly push you backward as it inflated. Up and up she rose until she quite literally doubled in size. It was lucky she was laying down, otherwise, you would not be able to mount the now 16 feet tall mare. Her body in terms of mass was like that of an elephant.

You leaned forward and left a soft kiss upon her right buttcheek. “You are so beautiful, Lilith,” you said softly, looking in awe at her massive buttcheeks.

“We thank thee. Is our size to thy satisfaction? We can use spells to hold back any further growth, or make ourselves smaller if need be.”

“Your size is perfect. Still, I like seeing your ass get bigger. It’s a wonderful sight. Don’t be afraid to have a growth trigger. You can always make yourself smaller if need be anyway.”

Lilith sighed sadly. “Anon, we wonder why thou love us? We are not good mare.”

“Lilith, Nightmare Moon didn’t kill anypony, right?”

“No. She did not. Even Nightmare Moon was not so evil.”

“Then you can undo what you have done. Bring out the sun, and free my friends from their stone prison.”

Lilith made to stand up to her full mighty height. Your words empowered her as she grew in size once more. She took your breath away. Her buttcheeks jiggled about wildly, along with her asscheeks coming to slap each other with loud meaty slapping sounds. Up and up she rose, until she quite literally became three times larger in size. She now stood over 50 feet tall. She was bigger and stronger than ever before. Her buttcheeks were now so large, they were practically blimps.

“Yes, we shall change our wicked ways. Your belief in us has empowered us. We wish to be no longer seen as evil.”

With a flash from her horn, she made herself back to 8 feet tall again. The mare then wrapped your body in a magical glow and placed your naked body upon her back. Her bridle and reins appeared again around her muzzle in a blue flash of light, you put your boots back on, you remounted your mare again as your massive erection poked against the soft fur of her back, then you grabbed the reins.

“Alright girl, let’s head back to the castle! Hyah! Giddyup!” You shouted as you jabbed your spurs into her barrel when you shouted, ‘Hyah’, earning a whinny from her as she galloped away.

The two of you made your way back to the Castle of the Two Sisters. There you saw the sight of your six friends frozen in stone. With a flash from her horn, Lilith brought out the sun. From a circular skylight window above, the sun shined upon them, and the six mares were unfrozen. All six mares looked around in confusion at what just happened.

“Did . . . did we win?” asked Rainbow. Her eyes widened when she came to look upon you and Lilith.

Lilith opened her mouth to speak, but she was cut off when her body flashed with a blinding light. When the light faded, a far smaller light, blue alicorn materialized before her. This new alicorn could only be Princess Luna.

“We… we are free from Nightmare Moon?” said Luna, her voice in awe as she looked up at the far taller alicorn standing before her.

“We no longer go by that name. We are Lilith. We are a new mare and wish to atone for our wicked ways. It took Anon's love to help us see the light.” Fluttershy flew up into the air, and sat down on Lilith’s back. She lay her two front hooves on your shoulders, and pressed her head against yours, taking you into a deep kiss. Her long, equine tongue came to enter your mouth. Lilith was not in the least bit jealous. She didn’t even turn to look back at Fluttershy kissing her rider. “As you can see, we care not that Anon is kissing one of you. It would be cruel of us not to share him with you.”

Princess Celestia materialized out of thin air before Luna, and took her into an embrace. The two mares cried as they lovingly hugged one another. As happy as you were that everything was fixed, you really wanted to have a threesome with Fluttershy and Lilith.

As if Lilith read your mind you heard her speak. “Forgive us, but our rider wishes for some alone time with us and Fluttershy. So, we must be on our way.”

With that, Lilith turned around, and made to walk out of the room. You reached your right hand back, and slapped her rear, causing it to jiggle, and her body to slowly inch upward. With a flash from her horn, Lilith amplified her growth even further. She subsequently blasted upward by quite literally ten feet. She was now 18 feet tall from that single slap. A thunderous, meaty clapping sound echoed through the room as her massive buttcheeks smacked against one another.

Celestia grumbled in jealousy as she saw that Lilith had a much larger backside than her.

It’s been a couple of months since you saved Equestria and freed Luna from Nightmare Moon, which you named Lilith and things have gone back to normal with your new roommate Lilith. When it was just the two of you, you would either go for a ride at night on her back and treat her like you would a horse would back on your world, or have hot and passionate sex for most of the night.

Fluttershy even joined us a few times and you noticed that the two of them seemed to be competing against each other to earn your affection. You already told them that it wasn’t necessary, but they keep doing it anyway.

But at the moment, you were packing your backpack, because you always wanted to travel around Equestria, I mean it’s a different world so you’ll want to explore it. You've been thinking about it for a while, but never had the chance to get around to it. Mainly because it would take forever since you can’t move that fast.

But now that you have Lilith as your mount, you can travel much quicker and easier, since she is your riding pony and you have Fluttershy as another of your travel companions. Lilith was returned to her normal, yet large size. She was back to being 8 feet tall.

Once you finished packing you walked outside where Lilith and Fluttershy were waiting. Lilith is wearing a dark blue saddle, with a matching bitless bridle and reins, she was waiting for you. While Fluttershy is just wearing brown saddlebags for traveling.

“Are you two ready to go?” You asked, making Lilith nod in response.

“Yes, I’m ready, Anon,” Fluttershy replied.

“Yes we are, but where are we going?” Lilith asked.

You walked up to Lilith, placed your foot into the stirrup, hosted yourself onto her back as you slipped your other foot into the stirrups and grabbed the reins, “I don’t know, but Equestria is big, so we’ll go with the wind.” You answered.

“We see that thou isn’t afraid about not knowing where to go?” Lilith asked.

“Nah, not really, after all. I have Fluttershy as my companion and have you as my mount Lilith.” You answered as you patted her neck a few times making her whinny happily in response.

You saw Fluttershy pouting, “I wish I can carry you.” Fluttershy said.

You smiled, “Don’t worry Fluttershy. Even if you can’t carry me like Lilith can, you’ll still be fun to have around.” You reassured her, making her nod in response. You turned to Lilith, “I still don’t understand why you won’t carry both of us?” You asked Lilith.

“Thou is the only one that we will carry on our back and that is a privilege that no other pony can have but thou.” Lilith replied.

“Then why did you allow Fluttershy to sit on your back at the castle?” You asked.

“Because we didn’t want to interrupt thou’s moment with the young pegasus and us carrying thou and thy was a one time thing. We won’t carry both of you again, we’ll only carry thou since thy is our lover.” Lilith replied.

You sighed softly, as you turned to Fluttershy, and offered her an apologetic look, but she shook her head telling you that, ‘it’s fine.’

“Well, at any rate, I’m glad that I can travel with you two as my companions.” You told the pair.

“I’m happy as well, since I don’t travel very much, but I always wanted to, but I’m afraid of going alone. I hope I won’t bother you too much.” Fluttershy said.

“Nonsense Shy, you’ll be great to have around.” You replied, making her smile and nod her head in response.

“And we are happy to be your mount as well.” Lilith told you as your smile widened.

You smiled as you tapped your heels into her barrel, “Alright then, let’s get this show on the road, hayh!” You shouted as Lilith reared up, pawed the air with her hooves, then came back down, as she and Fluttershy galloped away from Ponyville and into a new adventure with your companions.

And to think that all it took to tame Lilith who was the most dangerous mare ever were a couple of carrots, some sweet words, pets and ear scratches.

Maybe one day you’ll convince Lilith to carry you and Fluttershy at the same time, but for now, this is more than enough.
