Spooning

You, the human, lay naked on your side upon a lime green couch. Across from you, there was a certain white rabbit, who was sitting on a nearby green armchair. The rabbit glared at you angrily. It appeared he didn’t seem to be too happy with what you were up to. You did your best to ignore him for the most part. At least he wasn’t a bear. The owner of this cottage promised you a bear would not be here today. The owner was the one and only Fluttershy. As long as you treated Fluttershy well, you firmly believed you would have no issue with her rabbit. You seriously doubt her rabbit would inexplicably attack you, for that would upset Fluttershy. And you could not in a million years imagine yourself being cruel to Fluttershy.

You lay snuggled up to the beautiful yellow pegasus pony, spooning her from behind. Your head was buried in the warmth and softness of her pink mane. The mare's eyes were closed with a most blissful look on her face. You had your right arm wrapped around her barrel; your hand coming to rest on her warm and soft, yellow fur upon her chest. Her fur on her chest was particularly thick, which made it quite fluffy to the touch.

You could feel the mare’s feathery wings on her back twitching erratically against your chest. She appeared to be quite excited. Which was understandable, since you were sprouting a massive erection. Your towering meat was sandwiched between the soft and warm cheeks of her rump. Your cock was so long, the thick tip of your member came to touch off her silky soft tail above.

Down below, you could feel Fluttershy’s hot marehood was twitching excitedly against your thick cock. Your shaft came to be soaked with a steady stream of her liquid leaking out of her pussy. You didn't move; you were content to feel the softness of the canyon, between her asscheeks lovingly holding your member between them. In addition, the heat of her pussy against your cock was‌ almost like a hot boiler.

Between her hind legs she possessed a set of small teats. No bigger than a teacup each. In other words, crotchtits, or crotchboobs. So, for quite some time, you were quite content to simply hotdog the mare as you spooned her from behind. Before you finally decided to ask. “Fluttershy?” you said softly, in order to make sure you didn’t spook her.

“Yes, my friend?” came her beautiful feminine voice. It was like that of an angel.

“Can I pet your ass?” you asked.

“Yes. You can pet my butt,” came her soft voice, before shifting into a stern tone. “Just no funny business, mister. This is just a friends spooning session.”

“Of course, Fluttershy.”

“Thank you. I’ll give you a nice blowjob afterward.”

Your cock could not help but twitch excitedly at the prospect, which earned you a happy giggle from the mare. This only motivated you even more to be nice to Fluttershy. You were more than willing to be patient and go through this rather ridiculous, just friends spooning session with her. The fact is, you already spooned Twilight, Pinkie Pie, and most shockingly of them all: Rarity. All of them rewarded you by giving you a blowjob since you spooned them like a true friend. All three ponies were sexually aroused by the whole ordeal. But supposedly this was just friends spooning.

You didn’t care too much, since they gave you a just friends blowjob with passion afterward. Technically, you did not have sex with any pony yet. Just friends spooning was enough for you at the moment, along with a blowjob after it.

This was some truly bizarre, just friends spooning with Fluttershy. For you lay naked against her with a massive erection between her assscheeks while she was quite clearly sexually aroused. You decided not to question her about this. If this is just a friend's activity with a pony. You could only imagine what it would be like to be more than just friends.

You closed your eyes, and you raised your hand up away from her fluffy chest and placed it upon her cutie mark. Subsequently, your hand sank into the plush softness of her yellow ass like that of soft melted butter. Fluttershy moaned in bliss at the feel of your hand upon her plump rear. Something odd also came, accompanied by your hand landing on her rump. It was almost as if Fluttershy pushed her ass against your cock as you did so.

You decided to think nothing of it before you began to stroke her ass. Idly, your hand moved back and forth over her cutie mark. However, you felt more of the strange feeling of her ass seemingly pushing against your cock. There was also an odd feeling that the cheeks of her ass seemed to have spread open a bit. It was as if the space between her cheeks had gotten wider. Not only that, your arm seemed to be elevated up further than normal.

Soon, curiosity got the better of you, and you decided to investigate the matter by opening your eyes. You gasped at what you saw. Fluttershy had grown quite a bit larger than before. She must have grown about a foot. Her two teats became quite a bit bigger, like a grapefruit each. The pink nipples had become swollen, and you could have sworn you saw some milk leaking from them. You were tempted to investigate, but you dare not without her consent.

“Uh, Fluttershy?”

“Hmm?” she hummed.

“You’ve gotten bigger.”

“I know, keep going. And don’t stop, please. Twilight can cast a shrinking spell if needed later.”

With your fears put to rest, you resumed stroking her ass. Fluttershy moaned softly upon resuming her growth. You watched in delight as her ass began to air balloon outward in growth as it became bigger and bigger, fatter and fatter by the second.

Through her growth, Fluttershy rubbed her ass against you, sliding your cock back and forth between her wonderfully growing asscheeks. Your cock filled the gap between her asscheeks less and less, but you didn't care.

Fluttershy’s bubbly expanding asscheeks rippled about like a stormy ocean as more and more fat pumped into her glorious ass. The sight of which was quite simply breathtaking. You were not remotely afraid of being crushed by her growing rump since Princess Celestia had sat on you before. If she didn't break your bones, no pony would. There appeared to be some weight protection magic in place.

Fluttershy’s crotchtits swelled larger and larger in size, each one about the size of a watermelon at this point. The pressure from her growing caused her breasts to lightly spray milk as they pressed up against the couch.

The smell was intoxicating. “Fluttershy, can I please taste your milk?”

“Mmmm. Mmmm. Oh, yes. You have my permission,” she replied with a moan.

With her permission given, you ducked your head down and took her thick right nipple into your mouth. The yellow and pink pegasus moaned, and the teat grew more in size as it sat there in your mouth, coming to push against your face. Milk began pouring into your mouth and you hadn’t even applied ‘suction’ to it.

Her divine nectar tasted absolutely delicious. It was like a sweet, buttery cream. You drank from your friend in earnest. The cute pegasus panted and moaned to your affections, her front hooves playfully cuddling onto your head as you suckled.

You would have drank more from her tits, if you were not hit by a sudden tidal wave of fat yellow ass pushing you backward against the couch. Whatever you did, you seemed to have caused Fluttershy to have a growth spurt. Had she not had her hooves on you, part of you wondered if you would’ve fallen off said furniture. Her hooves were like that of Roman columns at this point in terms of thickness.

With her tits out of reach, you resumed playing with her rear. With both hands, you placed them upon her fat, bubbly cheeks. Your two hands came to sink into the thick, bubbly layers of soft fat like that of melted butter. Tears of joy fell down your cheeks as her ass resumed ‘air ballooning’ in growth.

Maybe… you are insane. But she seemed to get sexier and sexier with each new inch she grew. You were given more and more tits and ass with your continued love and affection. Above you could see the mare's mighty, feathery wings on her back spread out while she moaned in pure ecstasy as she filled out more and more of her home.

Soon, you found yourself almost drowning in a monsoon of marecum leaking out of her pussy like that of a river. Your entire body was soaked in a musky, yet fruity essence of her creamy marecum. With a moan, you licked up her delicious nectar, covering your face.

As more and more fat pumped into her asscheeks, it caused them to jiggle wildly from side to side; resulting in thunderous, meaty clapping sounds of flesh, slapping against flesh while her fat bubbly cheeks smacked together due to the rich influx of fat pumping into her bubbly rear.

Your hands upon her rear slipped further and further away from her cutie marks as her rump continued to bloat outward. Your hands sank deep into her thick, bubbly soft layers of fat. It melded at your touch like soft butter. You roamed your hands about her lovely rear. With tears in your eyes, you saw the depressions you left upon her rear quickly fade away, and return to a perfectly smooth shape from your hand’s absence.

Bigger and bigger, fatter and fatter, heavier and heavier, Fluttershy’s ass became before you. The sight of Fluttershy's ass continuously air ballooning outward in growth was ridiculously hot. You could not help yourself. Thus, with a loud cry, you found yourself unleashing a large explosion of your creamy white human cum between her wonderful, heavy, soft asscheeks. Spurt after spurt of creamy human spunk splattered against her lovely asscheeks; quickly filling the gap between her asscheeks with a thick and creamy load.

Fluttershy cried out in ecstasy while her cutie marks glowed with a blinding flash of light. This was followed by an avalanche of big fat yellow pony ass coming to slam into you as Fluttershy’s body was hit with a massive explosion of growth. The wind was knocked out of you from the sudden impact of her ass and huge tits against you. Her asscheeks were now like that of enormous beach balls in front of your face. Your entire vision was now dominated by the big, perfectly round and smooth, bubbly, yellow cheeks of her rump. The shadow of her massive ass loomed over your puny form.

“Mmmm! Yes! Yes! Yes! Feed me! Feed me your cum! Make Big Mama Fluttershy bigger and bigger!” she moaned aloud.

You were only too happy to feed her growth. Spurt, after spurt of your cum landed upon Fluttershy’s lovely asscheeks. Each subsequent landing of your cum upon her asscheeks caused her ass to ripple wildly like a stormy ocean as her rump bloated out in growth explosions like an inflating hot-air balloon. The mare moaned aloud as you fed her growth by your empowering love cream showering her ass.

Fluttershy was probably long since grown to the point that your cock was inadequate for her size, but you did not really care. For you loved big fat asses. You gladly contributed your cum on her rump. You watched in delight as her cheeks jiggled about like a raging storm as more and more fat pumped into her ass. Fluttershy was uttering deep throaty moans through her continuous growth spurts you provided her. This giantess mare getting bigger and bigger was so hot.

You sighed in bliss when you eventually stopped cumming on her cheeks. But at this point, Fluttershy’s ass alone might as well be an elephant, at the very least. As if by magic, your cock quickly rose back to attention, ready to make Fluttershy grow even bigger. You even felt your balls rapidly refilling with seed. Clearly some magical shenanigans were a foot. You didn't care in the slightest. Somepony decided to give you a much bigger and stronger dick than normal. It appeared you had a secret admirer.

The wooden legs supporting the couch you lay on began to creak from the tremendous weight of her body. Your cock was now largely insignificant compared to the semi-mattress-like canyon between her buttcheeks. Nonetheless, the mare was very excited, for her soaking wet marehood was leaking a steady stream of thick and creamy white liquid. Your senses were bombarded by a strong, musky scent with a hint of bitter fruit. The heavy cheeks of her massive ass sandwiched your cock between them; smothering them with the wonderful, heavy softness of her fat rump’s cheeks.

You halted your stroking. Your hand did indeed lay on her right buttcheek, but it could not reach her cutie mark anymore.

Fluttershy whined. “Don’t stop! Mmm! Keep going! Feed Big Mama Fluttershy your love.”

You went back to stroking her rump, and you watched in delight as it resumed air ballooning outward in growth. A few seconds into the stroking of her ass, the supports of the couch snapped from the tremendous weight of Fluttershy’s massive ass. You did not relent, and you continued to stroke her rump.

Somehow you were given a third person perspective. You now saw Fluttershy looming higher and higher into the air. The mare was basically like that of a school bus in the living room. She was a lumbering giant several times the size of an elephant, at the very least. Her tits were like that of a small car.

And yet… she kept growing with each stroke you made upon her rump. Steadily, her ass began to push her couch against the far side of the room against the wall as her ass continued to air balloon with each additional stroke you gave it. Soon, dust and debris began to leak from the ceiling. You stopped stroking her rump. You now feared Fluttershy’s ass would end up bulldozing down her house.

Fluttershy’s ass completely dominated you. Your entire body was smothered by the plush, warm, bubbly softness of her ass covering your entire body. Your cock stood erect, poking against her rump. The soft fat of her cheek folded around you like soft pizza dough. You hissed in pain at the great and terrible weight of Fluttershy’s ass bearing down on you. Yet, you weren’t afraid. For you knew there was some protection magic in place.

“Uhh, Fluttershy. I think we should stop now,” came your muffled voice…. But all you really managed to say was “Mmmmhhhhmmrrrrmma!” basically, or something like that.

Yet, somehow Fluttershy understood you. You could only guess it was magic, or something. “Oh… my. I think we got a bit carried away there. Can you fetch Twilight? I need her to cast a shrinking spell.” You attempted to move… but all you managed to do was trigger Fluttershy to grow even larger by a good few inches. Her cheek came to push against your body. “Oh my, you’re stuck.”

“What do we do?” you asked.

“We have two courses of action. One, we fall asleep here for the night and wait for somepony to come and visit, then they can get Twilight for help. Or two, you help me grow my way out of here.”

“What do you suggest?”

“I suggest you help me grow my way out of here. Besides, we have plenty of construction worker ponies looking for a job right now.”

“What about your animals?”

“They long since fled when I started growing.”

You shrugged your shoulders before you resumed stroking her rump with both hands upon her fat asscheek. Fluttershy moaned heartily as her body began to expand in all directions. You could see the cheeks of her ass pushing against the walls, the soft fat of her cheeks conceding back deeply against the walls like that of soft pizza dough.

Just when the walls were about to be bulldozed down, the walls and ceiling above seemingly began to push away from her, allowing Fluttershy to grow bigger and bigger with impunity.

The mare giggled, and made to shift herself over you, bringing her full mighty weight to bear on top of you. You hissed in pain from the immensely heavy rump of Fluttershy bearing down on you. You found yourself unable to move. She was quite simply too heavy.

And she was only getting heavier and heavier. Even though you weren't moving, you could see that her ass was still air ballooning. Despite everything, as if by magical intervention, your cock stood perfectly fine as it poked against her rump.

“Oh, yes. Feed Big Mama Fluttershy your love!” she said in a hot breathy voice. You could only utter an incomprehensible moan into her ass in response. “Oooh, let Big Mama Fluttershy take care of you.”

The mare began to grind her ass back and forth over you; like a gentle steamroller. The mare giggled and moaned heartily as she kept growing and growing. The thunderous clap of her asscheeks could be heard as her hips rocked back and forth. You were a quivering mess under her. The tidal wave of the heavy softness of her rump bombarding your puny form was absolutely wonderful.

“You are so cute! I love the feel of your small cock against my ass!”

The mare lifted her massive ass high into the air, before slamming down upon you with an earth shattering kaboom. You hissed in pain from the heavy impact. Before you had any time to recover, Fluttershy lifted her ass again and slammed upon you again and again and again.

Each time her ass slammed down on you, it came accompanied with a large growth spurt; this ensured that her butt slams would get more and more powerful each time. The mare moaned in bliss at the feeling of her continuous growth spurts.

Her buttcheeks alone were about the size of a school bus at this point, and they were only getting bigger and bigger, fatter and fatter, heavier and heavier.

“Do you love me, your big gentle giantess?” she shouted, slamming her ass down and then grinding her hips back and forth over your puny form.

You could only utter a muffled moan into the soft, bubbly flesh smothering your face. Your cock twitched, before you ended up repeatedly ejaculating upon her ass; unleashing spurt after spurt of your creamy human spunk upon her lovely rear.

Fluttershy craned her neck back, her tongue lolling out of her mouth as her body was rocked with a massive explosion of growth. Like raging tidal waves, her massive asscheeks raced toward the walls, outpacing the walls’ expansion; all the while her head shot up toward the ceiling above.

There came a loud crash as Fluttershy’s asscheeks bulldozed down the walls of her home, along with her head bursting through the ceiling. The massive titaness mare grew further and further into the air, knocking over nearby trees during the process, and subsequently crushing them into sawdust beneath her incredible weight.

By the time you stopped cumming upon her rear. The mare became quite simply gigantic. She must have stood several times taller than Ponyville Town Hall. Each one of her asscheeks alone must have been at least the size of Applejack’s barn.

“Oh… my,” said Fluttershy, blushing profusely at her newfound size.

You sighed sadly when the mare stood up. Fluttershy stood like a titan over you. The shadow of her massive ass loomed over you. The thickness of her legs were like that of milk silos. Speaking of milk, her massive, hot air balloons sized like tits between her hind legs were dripping milk down upon the ruins of her home below. Not to mention, her sexually aroused marehood was winking repeatedly, as it gushed out a thick and creamy river of her marecum. This river of pony spunk came to touch off her left, bubbly thigh, and subsequently flowed down her thick back hind leg, before eventually reaching the bottom to create a pool of her creamy marecum below.

With a giggle, Fluttershy reached her right hoof back and placed it upon her cutie mark. Her hoof upon contact with her ass subsequently sank deeply into the soft, melted buttery softness of her rump. This created a wonderful deep depression upon her butt like that of an asteroid crater. She held her hoof in place for a good few seconds before slowly pulling back. You watched in delight as her rump resumed a perfectly smooth, round shape like that of a lake.

Fluttershy flared out her mighty wings, spreading them out like a jumbo jet on steroids. She then experimentally began to bounce her ass up and down. The fat cheeks of her gigantic ass jiggled about wildly like a stormy ocean during her rapid movements and also ended up creating a thunderous meaty clapping sound as her big fat asscheeks came to slap against one another during her violent movements. You stared with your jaw dropped at this magnificent display. It was quite simply breathtaking.

As if on cue, in response to your awe and wonder, the pegasus experienced yet another growth spurt. The mare moaned aloud as she shot up into the air, blasting you with a heavy load of her marecum. The mare within the space of a few seconds had quite literally doubled in size.

You sighed sadly when the mare abruptly stopped bouncing her ass.

“Let’s go find Twilight… before I grow out of control.” Just then her home seemed to spring back out of the ground, good as new as if nothing happened. “Or I could grow even bigger if you like. No harm done.”

Fluttershy slammed her massive ass down upon you and grinded it back and forth over your puny form. She moaned heartily as she resumed growing bigger and bigger, fatter and fatter, heavier and heavier. It was like a drug to her. She could not resist. She wanted to get bigger and bigger.

Fluttershy’s asscheeks air ballooned towards the town and began to crush them under her great magnificence. The ponies were unharmed, but they were smothered under her great bubbly softness. Her growth rate accelerated. Grow… grow… and grow…

There then was a flash… you and her found yourselves back in the Fluttershy’s home. The mare was returned to normal size. Merely four feet tall, or so.

“Awwww!” she whined.

Fluttershy’s rump was pressed against your crotch. Your cock was sandwiched between the lovely cheeks of her ass. The mare moaned when you placed your right hand upon her cutie mark. The mare resumed growing bigger once again upon contact, her rump air ballooning against your body.

“Don’t worry, Fluttershy. I’ll make you big again. My beautiful gentle giantess,” you said softly.

To this, the pegasus leaned her head back and softly kissed you on the chin. “I know, sweetie. I know.” she giggled.

You now had a good theory why Fluttershy was so shy. Not everyone would appreciate her getting bigger during intimacy. They would run away like a coward.
