Expansion Erotics and Magical Maladies

A large, luminescent moon hung in a deep black, cloudless sky, casting a pale light upon the ground below. A cool, rasping wind, blew through a small embankment, the thick bushes rustling and shaking in the gust. This embankment lay at the side of a stream, meandering its way through the rock and mud of the channel, winding past a myriad of trees that stretched high into the sky, creating a wide canopy that kept the undergrowth in near constant darkness.Through these bushes, a slender, mud spattered yellow limb pushed through, scrabbling to haul herself up from the small cliff.

Fluttershy was utterly terrified. First, she had been sucked into a book, and the next thing she knew, she was in the depths of some forest. A forest that was seemingly devoid of any animals. It was such an eerie experience, such a dense, lush habitat, without any birds, reptiles or mammals. She hadn’t even seen any insects buzzing around or crawling up the trunks of any of the wide, somewhat twisted trees. “It’ll be OK… just… keep walking and we’ll find our way out…” the mare whispered to herself, trying to break the white noise that the wind and the crunching of leaves underhoof provided.

The wind picked up briefly, howling and shrieking, sending a chill through the mare as she buried her face in her mane. Still though, she carried on, hoping to find something that would help her. Pushing through another clump of overgrowth, catching multiple thorns and leaves in her mane and tail, she glanced up, finding herself in a clearing. There were no trees for several meters upon a piece of raised ground, which seemed to be blanketed in a thick layer of knee high bushes, so dense that she could barely see the ground below.

Trotting forwards, she glanced up, looking at the barren moon, hoping that she could find something to get her out of the endless miles of forest. But whatever happened she could… “Ouch!” Fluttershy lept forwards, a sudden jolt of pain rushing from her leg. Stumbling forward, she managed to clear the brush, now in a flat plain, composed of mostly bare rock and small grasses. Looking down, she spotted a small barb sticking out of her leg. Pulling it out with a swift yank, cringing after another jolt of pain, she lifted it up.

Distinctly plant-like, it had a needle thin point, with a pair of round fruits at either side, the skin of which was deflated. “I...i was injected? Was it… poison?” Throwing the barb to the side, she looked around, hoping she would find somewhere to go in these desolate woods. Huffing, she had no choice but to continue, noting that the sting seemed to have gone away. Thankful that she didn’t have to hobble around alone, but still worried what might happen, she crossed the open field, disappearing back into the woods.

Keeping her eyes peeled to make sure she could find anything, Fluttershy became increasingly aware of an odd rubbing feeling between her legs, like something was smacking into the front of them. Putting it down to feeling tired, she ignored it, unaware of the changes being inflicted upon her. Expecting some awful poison, instead she had been injected by a very curious piece of flora. As soon as it had entered her blood stream, the injected chemicals actually had a more, interesting effect, rather than simply paralyzing her organs or destroying her cells, instead it made some other biological changes.

This had caused the mares teats, which up to this point were unnoticeable, to start to undergo a biological shift. Once the chemical reached them, they started to grow rapidly. Every step she took, the tennis ball sized teats would collide together and against her back legs, with every moment only increasing the sensation, the growth unabated.

“Why is walking becoming so hard?” Fluttershy mumbled, stepping over a fallen log. “Must be the poison from that plant. Stupid me, why did I just wonder into there?” Berating herself, she continued to ignore the sloshing pair, now just shy of volleyballs by size, though not as round. In addition to the new size, milk had formed too, just on the cusp of being audible from every hoof step taken. Moment by moment, second by second, her pace slowed down, breasts so hefty that pushing past them every step had become a chore.

“For crying out loud, why am I so…” she glanced back, taking a moment to process what was happening to her. Bulging out from between the sides of her belly, each tipped with a thick nipple, she gazed at her new milkbags. “Wuhhh… wah?” She attempted to speak, so dumbfounded by the oddity. Slowly, she made her way over to a log, sitting down, now fully aware of the sloshing, jiggling blobs dangling below her. Planting her yellow bottom onto the fallen tree, she took stock of her new assets. Each larger than bowling balls, and each feeling as heavy, the pair filled her lap, forcing her to spread her legs apart to give them more space.

“Where did these come from… I didn’t think teats could get this… big.” She blushed, reaching her hoof out and caressing one of the milky orbs. “Oh my… it’s so heavy… and squishy.” Resting against it, she could physically feel her hoof being pushed back, centimetre by centimetre as the growth continued unabated. “And they’re getting bigger still!” She could do little but watch, as they ballooned larger than soccer balls, more and more lactate filling a pair of ovoid masses the size of her head.

Carefully, she attempted to get to her hooves, watching in a mix of pleasure and shock as they filled the gap between her legs, touching both front and hind legs, squishing around her limbs. Attempting to take a step was immensely difficult, her hind leg slapping into her breast, jostling and wobbling them, causing her to gasp, letting out a moan. A burst of lust flooded into her mind, just as those pendulous orbs began to graze the ground, with each exaggerated slosh. Realising that any form of locomotion was becoming very difficult, she shuffled back towards the log, sitting again.

“Huff… nffff… oh my… there sooooo heavy… ha… makes it hard to keep balance.” Indeed, just sitting was becoming rapidly more difficult, simply due to the humongous counterweight currently being pulled down by the intense force of gravity. A problem that was somewhat remedied when they became firmly planted on the forest floor. Their continued march to become as large as the creature they were attached to went unabated, as her breasts squished out like water balloons, her fat nipples pressed outwards, thin beads of white fluid leaking from them.

Immobilised by her own breasts, she was forced to sit there, every minute that passed adding more mass to her monumental mammaries. And every moment was pleasure, her stretched skin incredibly sensitive to each poke and jostle, letting out spurts of milk every time. Unable to do anything but allow herself to take up more and more room, each boob easily more massive than the butter yellow mare's entire body. Legs spattered in mud, mane and tail full of twigs, leaves and other forest detritus, and the largest pair of breasts ever witnessed that rivalled adult bears for their size, she could only wonder what odd pleasures her friends were experiencing.
