"Make my breasts giant, he said...99% chance of success, he said..."

The ground shakes violently. Entire buildings sway, and the ground shakes once more. Again, the sounds 
of windows breaking, objects falling over, pavement cracking fill the air, but are overshadowed by the 
echoing boom of footsteps. A water tower topples, though this was not due to the quakes: it was the 
accidental wobbling of a giant Kirlia's breasts, swollen up to relative basketballs on her chest.

"Rrgh, damn things...I oughta show that guy a what-for, but I don't think I can find him like this..."

She cursed her breasts under her breath, making her way down a highway, the gaps between buildings 
just wide enough to let her pass through. Her appearance was so sudden, people still on the ninth story 
of these structures could get a glimpse of her face as she passed by. The gigantic tits on her chest made 
it hard for her to tell what she was stepping on, and flinched every time she heard the resounding 
crunch of a car, sign, or other metallic objects being crushed in her path. Of course, she thought of it all 
as accidental. Her breasts were to blame for being too large.

Stopping at a wider, structurally-sound building just high enough to meet halfway up her boobs, she 
hefts them up and sets them on the flat top of the building with a sigh. It creaked and bent, but held...at 
least for now. She took these few precious moments off from thinking of how heavy her tits were, and 
tried to think of how she could get back to a normal size.

Or at least, she thought she would. The stroll through the city streets has brought to her attention just 
how large and sensitive her breasts had become, only just hours before being nubs on her washboard 
chest. Now, being so overgrown to even a regular-sized Kirlia, each gust of wind that blew against them, 
each little movement that caused friction between them and another object, each little squish from her 
hands...all of it made them feel tingly on the inside. It was why she wanted them large in the first place. 
She just didn't count on becoming a giant in the process.

Sirens wailed through the city as its citizens evacuated swiftly, with not a single soul being within two 
hundred feet of the overgrown Psychic-type. She hesitated to rest her head on her chest, given the 
struggling structure underneath barely able to hold up. Curiously, more creaks and groans welled up 
from the building, the Kirlia looking at her chest puzzled at why it was continuing. The only logical 
explanation, given that there wasn't anything else that'd cause it to buckle, was that she was growing.

The sudden caving of the structure was proof enough that her boobs were swelling on their own, the 
Kirlia only just able to keep standing after the massive shift in weight. The downward force of her 
breasts caused streams of milk to flow from her nipples, no doubt a side-effect from the enhancements 
placed on her. Stepping back and seeing the milk puddle, she didn't think it was coming from her 
breasts, but upon groping herself and feeling around her nipples, she confirmed she was lactating.

Not wanting to be overburdened, she looked around for some place to store a massive amount of liquid, 
as her breasts were feeling heavier by the second. Luckily, at the end of the street she was on, there was 
a wide expanse of water - a landlocked lake. It would have to do. She ran towards it, with little regard to 
how her breasts bounced back and forth, smacking into buildings while also leaking streams of milk, 
each drop capable of breaking windows.

Finally at the edge of the water, she got on her knees so that her breasts touched the ground, and 
started to massage them near her nipples. She cooed softly, the pleasure hitting her hard, but she knew 
she had to keep her tits at a manageable size or she wouldn't be walking anywhere. Thick geysers of 
milk sprayed from her nipples with each stroke, lessening her breasts' loads little by little.

However, when she switched breasts, she could feel the first filling back up. She tried massaging faster, 
but aside from her nipples spraying milk faster, she couldn't seem to handle both nipples at once. 
Within minutes, she was unable to reach her nipples thanks to her tits growing to 3/4ths of her size. 
Unable to reach them, she used her body's weight to squish down on her breasts, trying anything to milk 
them down, but it seemed useless. Not even her giant body was going to be enough to put a stop to her 
tits.

She groaned, feeling them fill up faster and faster. They spilled off into the lake, having turned white in 
some areas thanks to her milk. Having stopped milking, her nipples puffed out, only a few rubs away 
from unleashing a torrent, yet it didn't come. The Kirlia squirmed and moaned, wanting to milk herself 
to stop this feeling of fullness. "S-stop growing...! Too much...!"

They swelled forth, a great deal of her breasts now in the lake. Twice her body's size, the tits continued 
to rumble with production, only picking up speed with her body's desire to lactate. Fortunately for her, 
when her nipples met with the cold lake water, the stimulation from the touch and temperature was 
enough to send her into orgasm. She hugged her breasts tightly as they let loose cannons of milk from 
each nipple, filling the lake with whiteness and causing it to spill over the edge of the dock. The city soon 
became swamped in this mixture of water and milk, but the Kirlia cared not in her bliss.

Her outburst of milk was enough to stop the swelling for a time, as they had managed to lactate fast 
enough to meet her production, but with the ante upped, her breasts kicked into overdrive to meet her 
supposed lactation needs. Three times her size, four times - it seems like every ten seconds they were 
picking up speed. "N-no~! D-don't...grow more...! S-slow downnnn...!"

Her massive breasts reached the other side of the lake - or where it initially was. Milk spread out across 
the land for at least a mile in front of her. The Kirlia pushed against her white wall of titflesh, practically 
begging for them to stop. "T-too full! Too much milk! I-I'm big enough, please stooop~," she wailed, but 
her body had already made up its mind. Already she could fit the entire city's area atop one of her 
breasts and still have excess room. The ground rumbled as her tits again picked up speed, and she cried 
out once more, in a mixture of denial and pleasure...
