Sera stood there biting her lower lip as she examined the two different cookie flavors.

"Sera, come on! Make a choice already." Her twin sister Shea huffed and leaned on the cart.

"But I can't choose which one I want. I mean, we got minty chocolate chip last week, and I loved it. But I've been hungering for classic vanilla, too." She whined, the collie's ears drooping. Her sis rolled her eyes.

"Just get both and be done with it."

The blue and white collie girl shrugged, placing both in the top basket as her sis pushed. Although twins, the collies were easy to tell apart. Shea's right side of her head was white, as Sera's was on the left. In fact, that was the only way to tell them apart by looks alone, their body's shapes an figure were identical.

Most furs on the outskirts of the city where they lived knew the girls rarely left each other's side. Men had tried to go on a date with one or the other, but it usually ended with a turn down for a second date. There was a rumor that they liked each other's company more and "experimented" with each other. Only the girl's knew this was a an actual fact. A dirty secret to themselves.

Sera scribbled cookies off the list as she read over it.

"Okay, we just need milk, yogurt, and bread."

"We're out of milk again?" Shea growled.

"It's not my fault we drink too much."

"You mean you drink too much with needing to eat so many cookies." Shea poked her arm.

"So what if milk and cookies is my favorite snack? You eat them, too." She retorted. Shea had no comeback to that, it was true.

"Free sample here. Gerchier's Milk. Newly enhanced formula. Guaranteed to make your tongue tingle." An orange and black striped tabby cat sales merchant offered to other shoppers, but no one touched the cup.

"Oh, free samples." Sera cooed, walking over with her sis behind. The tabby handed her a cup.

"Would you like to try miss?"

Sera took the cup and drank it in one swig. The taste was phenomenal. It was rich and creamy, almost vanilla like. It really did leave your tongue tingling.

"Oh sis, you need to try this." As she held another sample to Shea. She shrugged and gulped it as well, her eyes widening to the taste.

"Oh wow! Its so good." She licked her muzzle. "How much is it?"

"It's two half gallons for three dollars." The sampler replied.

"We'll take four." Sera quickly move behind the tabby, grabbing the cartons from the fridge behind him.

"Have a nice day!" The tabby waved as they moved on.

"Augh! $76.34? What did we buy?" Shea grumbled as she looked over the receipt.

"Well, the milk was six, the cookies another six, then the meats..." Sera rambled off. Shea rubbed her temple, then reaching down and adjusting her bra awkwardly.

"I think my bra shrunk just now." She looked down at her breasts. Were they larger?

"I think so, too. I must've put them in the drier too long again." Sera turned into their driveway to their home. It was a simple single story, two bedrooms, a kitchen that led into the living room, and a washroom.

"But shrinking just now?"

"Nah, we must've been too preoccupied at the store to notice." Sera concluded, hopping out and taking the groceries in.

Once settled, Sera plopped down on the sofa, swinging her feet on to the coffee table. Her eyebrow perked a bit. Usually just her ankles were on the table, now it was a quarter of the way up her calf. He shrugged, figuring she must've bumped the table while vacuuming and pushed it towards the sofa. Sitting both packets of cookies on the middle seat, she quickly opened them, placing her tall glass of milk on the stand at the end of the sofa.

"You know these are suppose to last us a week, right?" Shea sat on the other end with her own glass. Sera snorted.

"They won't last a day." As she flipped on the T.V. With the remote, turning to their soaps with the occasional dipping of the cookie in the milk and eating.

As time went on (apparently Fredrick had fallen down an elevator shaft and was horribly injured) Shea kept rubbing her one breast. It felt swollen, almost...full. She quickly gasped and stopped as she felt a moist spot. She quickly looked down inside her bra, seeing a wet nipple.

"Oh my God! Sera! I'm lactating!"

Sera turned and looked.

"That's impossible. You've never been..." She trailed off, seeing the wet spot. "How?" That wasn't the only thing. Shea quickly pointed to Sera's legs, which were slowly sliding along the top, her knees almost on top of the table. She then saw her own legs were the same way. Sera quickly jumped up, the top of her head only a foot away from the ceiling.

"We're growing!" She gasped, feeling her clothing tightening over her body.

"That's impossible! Nothing just makes furs grow!" Shea whimpered, standing up as well.

"What do you think it was? The cookies?"

"No, we've eaten them before and this never happened!"

"Then the..." Sera trailed off as they both looked at the glasses.

"The milk!" They said in unison.

"What do we do? Call 911?" Sera gulped, going for the phone. Shea wasn't paying attention, she was once more rubbing both her breasts with her hands, the front looking soaking wet. "Shea, what are you doing! Stop that!"

"I can't! It feels so good and hot!" She moaned, biting her lower muzzle. Sera could smell her sister's scent rising in the air.

"This is no time for-" but she could feel it, too. Her breasts were so full, so tight, so...sensitive. Just the fabric moving along them as they expanded caused her to shudder. The seems in her jean shorts were beginning to pluck apart, her button popping off and flying across the room as her zipper slowly undid itself.

Her shirt sleeves rode up along her forearm as far as they could before being stretched pass their limits, starting to tear. As her chest pushed outwards, her shirt rode up, revealing her white, flat stomach. There was a snap as her bra gave up the fight in the back, the straps pinned inside the tightening fabric, unable to fall off.

Gingerly, Sera began to rub her own breasts, moaning in bliss. Shea already had a hand down the front of her tight pants, groaning as her head thudded against the ceiling. But as quickly as it started, the feeling and growth stopped, leaving the twins panting.

Neither spoke a word, their eyes told each other the same thing. More.

Both managed to barely squeeze into the kitchen, ripping open the fridge door. Sera grabbed the two unopened cartons, sitting on her rump and leaning her back against the sink as she ripped open the tops, chugging down the sweet liquid. Shea grabbed the other and made her way back to the living room, finishing off the two glasses before drinking her own carton.

The effects were almost instantaneous as they drank. Their breasts filled more as their shirts began to tear down the collars, letting their massively filled orbs leak freely into the air. A free hand went into Shea's shorts once more, her panties looking more like a soaked g-string as her thighs began to burst through the fabric. Sera's feet began to push against the opposite wall, the collie having to bend over as even while sitting she was touching the ceiling.

Furs walking outside could hear the moaning and the scent coming from the home, stopping to wonder what was going on in there. It wasn't until a massive white foot with black pads burst through the front of the house caused the gawkers to run screaming. There was a horrible cracking sound, like multiple trees bending and snapping at the middle, as the roof bulged, then exploded as Sera stood, followed by Shae, the remains of the roof sliding down their backs, their paws pushing away the remains of their home.

Shea looked at her sister and murred, licking her muzzle.

"God sis, you look so hot like that." She panted, pulling her in and licking over a dripping breast. The taste was familiar, too familiar. Sera moaned as her sister quickly latched on, drawing and feeding from her breast. She grunted, rubbing in between her sister's ears as she fed. Her hand soon stopped in bewilderment as something didn't seem right. Sera's eyes widened as soon enough ,the top of her sister's head was up to her chin, and she was on her knees!

"Shea! You're growing bigger than me!" She gasped out. Shea pulled off, grinning.

"Your breast milk sis. Its the stuff. We're walking factories of it!" She panted before pushing her sis down, Sera falling on to the neighbor's home and crushing half of it. Shea quickly pinned her "shrinking" sis, latching on to the other breast and drawing, hard. Sera groaned loudly in both bliss and fear as her sister grew, soon twice the size of herself!

"Sis! You're getting too big! Pulling too hard! Let me drink from you!" She cried out, pushing against her twin's head. Surprisingly, Shea released, giving a low burp and licking her muzzle, a gleam in her eye.

"You wanna drink? Fine." Shea brought her thick and still growing form over her sis, shoving her sex against her muzzle. "Then get licking."

Sera should've seen this coming, its what she would usually do some nights to show she was the older sister (by six seconds). But she didn't care, she wanted to get huge, too. She began to lick along the insides of the walls, tasting her larger twins juices as they leaked down onto her. She could feels the walls expanding along her tongue, her sister's weight starting to really get heavy as she was soon just a third of her twin's size.

"Shea! I can't breathe!" She called up, the larger collie busy groping her breast, her tongue lolled out to the side as her tail thumped, basing in another neighbor's home into the ground.

Shea looked down at her struggling twin, standing up and picking her up easily in two hands.

"Okay squirt. I guess that was enough." She giggled, moving Sera to a breast and letting her latch on to drink. Shea gasped in surprise at the rate her sister grew, it was much faster than her own.

"Oh God, sis, I think the larger we get, the more potent the milk!" Shea gasped out, Sera already touching the ground as she drank, soon up to he twin's height before releasing and panting.

"Then let's really have some fun!"

Downtown knew something was up on the outskirts of their city, but no one was sure what it was. News vans were speeding through the streets as helicopters took to the sky. Everyone stopped in their tracks though as the ground shook. Furs looked to the East, seeing a mob of others running and screaming, pushing and stepping over each other. The shaking grew more intense, more rapid, car alarms going off and anything not anchored into the ground fell over. Two figures loomed over the streets, at least two hundred feet tall. The collie twins giggled down at the small furs as they ran from their feet. Car, buses, everything was flattened and crunched as they moved forward.

"Everyone is so small!" Shea giggled before kicking a car forward, sending it flying down the street and into a building.

"Everyone is our toy!" Sera giggled back as she smiled at a glass skyscraper as tall as her, admiring her reflection. The furs inside gawked in awe at the nude collie, her chest at least having expanded from C cups to DDs now. Slyly, she gave a wink to the furs inside.

"Wanna closer look boys?" She moved forward, pressing her mammaries against the glass as she wrapped her arms around the building. The windows lasted a mere second before giving away to the white flesh as any furs who dared to be close were flattened. Sera moved forward and hugged the building more, starting to crush it as her breasts plowed forward, pressing others against and soon through walls. In mere moments the building began to collapse in her grasp and crumble to the ground.

Shea was more interested in the tiny furs as she scooped them up, giggling as they squirmed in her paw. She dropped them in between her breasts as they wiggled and tried to grab on to the fur or something to keep from falling to their deaths. Shea only moaned as they scampered over the sensitive flesh, rolling the breasts together to make them scamper about even more. Soon, however, most either fell to the street or mashed to a pulp, the collie only reaching down and grabbing another handful, getting another kinkier idea. She began to shove the next crowd, bit by bit, into her vagina. She nearly came from the result. So many tiny squirms inside her, trying to discern up from down, in from out. Her knees nearly went out from under her before she clenched, instantly ending the wiggling. She panted and turned to her sister.

"Sera, you gotta try stuffing them inside you!" As she grabbed a few more off the ground, taking her sis by surprise just as she turned, stuffing the helpless furs inside her. Sera gasped and grabbed Shea's shoulders, her mouth agape as she moaned and thrust forward, crushing them.

"Damn, that was hot! But you know what would be better?" Sera grinned, turning her head to the side and gently lifting up her sister's breast, latching on and drinking. Shea meeped and moaned, doing the same as they drank from one another.

The survivors watched in horror as the twins began to rapidly expand. Three hundred, four hundred, five hundred feet came and went. Their heights only continued to skyrocket larger, their paws plowing over buildings, crushing cars, and catching any furs who dared to stay behind.

Finally, they released, the tallest skyscraper barely matching up to a single toe. Sera murred and nipped along her sister's neck, moving upwards before deeply kissing. Shea moaned, gripping her sister's rear and squeezing as their tongues played. Once they broke, Shea fell on to her back with a earth shaking thud, Sera assuming the 69 position over her sister. It was something so common between the two that they started nearly at the same time on each other, hungrily nipping and licking at each other's inner muscles. Sera's feet dug deep craters into the remains of the city. Shea's thrusting was causing small tremors that were felt by the next city over. Their scents washed across the countryside, causing furs to either pass out from the concentration from being so close, or to have sex with the nearest fur close to them. Their juices alone flooded the streets, washing away anyone left or drowning. It didn't take long for both to taste each other's climax, licking their muzzles clean as Sera turned and laid beside her sister, giggling and drawing her in for another kiss.

"Delicious as always sis."

"So were you."

They both giggled and let out a low happy sigh, falling asleep in each others arms
