Just a very short story idea I had about the aftermath of a trainer (I.e. you, the viewer) testing some Lopunnite out on their Lopunny, with...interesting results, hehe BP Enjoy~

I left the gender of the Lopunny and trainer both ambiguous, so imagine whatever you want for it ;P

---

"Like what you see~?"

The light, lilting voice of the Lopunny chimed, giving you, its trainer a coy smile as it looked back at you. You can't believe your eyes as you look at them; the Lopunnite triggered mega evolution had succeeded, your Lopunny was now in its mega form, but...

It seems that the stone's power had made more than the Pokemon itself mega. As currently right in your face were the enormous, boulder sized ass cheeks of your mega Lopunny, each one larger than a yoga ball and sagging under their own weight. The Lopunny giggled and ran its paws over the exaggerated curves of its greatly expanded body, fingers ticking up the black fur of its thighs and across the slopes of each gigantic globule of ass, causing ripples across its surface.

"Definitely an improvement~" it said again, before giving a cheek a swift, strong slap.

You watch in amazement as the slap sends a jiggling wave of shifting fat across the surface of the cheek, which triggers the other boulder of meat to cascade in its own series of jiggles, a faint, watery slosh of fat can be heard as this occurs, your Lopunny just purrs to itself as it enjoys the sensations of movement.

The sheer size of its butt is ridiculous, each cheek was at least 2ft wide and round, giving the rabbit Pokemon a slow, waddling gait which causes undulations across its body with every sudden movement. They were already fairly pear shaped even before you triggered their change, and quite teasing already, but now it seems that the mega form had triggered not only a ballooning in their physical dimensions, but a marked increase in their affections towards you, more than platonically.

The Lopunny turned around finally, fluffy hands upon its wide, doorway jamming hips, that devious smirk still on its face. You can clearly see that its not just its rear that's grown out too; the bunny's belly is equally bulbous, heavy with fat, sagging over its crotch and squishing against tree trunk thick thighs.

"Seems that the stone made me quite...heavy, hm?" they smiled, waddling towards you at the pace of an obese snail, each step on a dainty footed, but monstrously thick leg sending earthquakes of fat jiggles across their body.

Sensing your fascination with their new form, the Lopunny grins and begins to slowly pose itself, trying positions which accentuate its bulk, each one barely able to be kept for long before the effort needed to maintain them was used up. After this, they began to more, shift around and dance slowly, each twirl, step and hop causing more sloshing avalanches of blubber to ripple about, and you notice the usually flat chest of the Pokemon has developed two sagging domes, each one would make a human lady somewhat jealous!

They stop short of you, after a while panting softly but heavily from the exertion, wiping sweat from their face with a thick arm. Its clear that this Pokemon is no good for battling in this state, and they seem like they'd most definitely not want to even if they could. You could hear a deep, rumbling growl bubble up from within their belly, which causes them to chuckle and place their paws upon it, those pink on black eyes looking up at you almost with a sultry longing.

"All this work is making me hungry, got any poffins~?" she asked, with that same, coy tone.

As you root through your bag to locate the treats for your enormous Pokmeon, you wonder...what would the other stones do to your other Pokemon?

A devious grin of your own spreads across your face.
