Rarity felt something squirming under her, wiggling around like mad. More unnervingly, she felt something wet. Groaning, she blinked and opened her eyes, then got to her hooves. "Eugh," she grumbled, noticing liquid dripping off her chest, "What-oh my..." She looked around and noticed what was all over her kitchen.

A very milky smell was in the air, but that seemed to be the least of Rarity's problems at the moment. Her entire kitchen seemed to have been flooded with milk, covering the floor, the walls, even dripping off the ceiling. Everything seemed to have turned white, and Rarity stood in the middle of it. She was at an absolute loss for words, and just stared at the massive mess that coated the whole room from top to bottom. Slowly, she simply backed up into the front room, little splashes of milk coming from every step while not blinking, until she was completely out of there.

Then she noticed a note on the table next to her favorite fainting couch. She levitated it over to her, and began to read the barely legible writing on it.

"Dear Rarity, sorry for mess in kitchen, couldn't stop leaking, tried to clean it but set broom on fire, went to go get help, Sweetie Belle.

PS I didn't go to school like you asked"

Rarity was completely motionless for a moment after reading the note, then looked down at the floor, spotting a white trail through the carpet towards the door. "Oh, no," she said, running out the door, "Oh, nononono! No!" She broke out in a full sprint down the road, desperately looking around for any hints of Sweetie Belle. "If anypony sees her like that, they'll-they'll-ugh!" she yelled, her head rapidly turning from side to side as she galloped through Ponyville. Eventually, she noticed a yellow mare walking down the road with a basket in her mouth. "Fluttershy!" she called, zooming up to her friend, "Quick, have you seen Sweetie Belle anywhere?"

Fluttershy turned to her friend and smiled. "Oh, yes, I saw her run by on her way to Sugarcube Corner," she said, quietly, "so, how have you-"

"Can't talk now, thanks!" Rarity yelled, galloping past her. After a few minutes of running like an absolutely crazy pony, she finally arrived at Sugarcube Corner and ran inside. "Sweetie Belle?! Sweetie Belle?!" she called out, desperately looking around in the room.

"Hey Rarity!" a happy voice called out to her. Looking forward, she saw Pinkie Pie waving excitedly at her from behind the counter, and she trotted up to her. "What'cha doing?"

"Pinkie Pie, where's Sweetie Belle, have you seen her?" Rarity asked quickly, still swiveling her head around searching for her sister.

"Oh, she's in the kitchen!" Pinkie Pie replied, pointing behind her.

Rarity stopped looking around and made a curious face. "The kitchen?" she said, "I thought she was permanently banned from the kitchen after the whole 'burnt ice cream' incident."

"Well..." Pinkie Pie said, rolling her eyes, "The Cakes are out right now, and she wanted to help, so I let her!"

"That's lovely and all," Rarity replied, becoming serious and walking behind the counter, "but she is in no condition to be WUAGH!" The moment Rarity entered the kitchen, everything seemed to go downhill for her.

The first thing she noticed was Sweetie Belle sitting in the corner with a very concerning look of absolute bliss on her face, cheeks blushing. The second thing she noticed was Pound and Pumpkin cake in front of her sister, holding onto her even more swollen breasts and suckling on her teats. Little pools of spilled milk were forming around her, as babies weren't well known for their excellent precision.

"Sweetie Belle!" Rarity yelled, running up to her sister, "Oh dear sweet Celestia!" She made a shocked expression that Pinkie Pie found endlessly amusing.

Sweetie Belle seemed perfectly content with the two infants. "Rarity...?" she moaned, slowly, “Ooooooh...” She began to make embarrassed giggles as her melons jiggled around between her legs. “I-I didn’t know it felt sooo goooood...” she whispered, leaning back with a stupidly happy expression, “Ooooooh..."

“Sweetie Belle!” Rarity yelled, becoming even more horrified, “Stop making that noise! And stop making that face!" Her voice became gradually higher as she barked commands at her sister, who didn't seem to pay attention in the slightest. Getting frustrated, she lit up her horn and attempted to lift Sweetie Belle off the floor, rising her a few inches. "Here we-agh!" she started saying, then bent over awkwardly as her horn suddenly yanked her forward. Rubbing her neck, she straightened out and looked as the filly suddenly flopped back on the ground. "Wow, those things are heavy," she sighed.

"Mmmmm..." Sweetie hummed, her silly look of pleasure coming back, "Just come back in...a few hours..." She jerked forward and her voice cracked partway through the sentence as Pound Cake decided to become adventurous with his suckling, which disturbed Rarity a fair bit. Rarity was, however, getting even more determined to her big boobied sister out of there and away from all other ponies as soon as possible, and had lit up her horn again, but stopped before lifting her.

"Hm..." she mused. Changing her mind, she lifted the twins up and pulled them away from her sister's teats, which immediately started to spill milk all over the floor. "There we go," she grunted, placing them on a nearby table, "Now to just-"

"Waaaaah!"

Rarity was suddenly interrupted as Pound Cake and Pumpkin Cake loudly began crying, but she continued to lean down to her sister. She said, "Come with me, Sweetie Belle, we're-"

"Oh my poor babies!" Mrs. Cake's voice rang from behind them. Turning around, Rarity noticed both parents standing next to them.

Mr. Cake turned towards Rarity with an extremely unhappy expression. "Just who do you think you are, Rarity?!" he yelled, coming towards her.

"Wha-where-how did-wha-" Rarity blabbered, then suddenly shouted, "Where did you come from?!" She turned away from Sweetie Belle, who was just now catching up to reality and attempting to cover her huge teats from leaking with relative success.

"What, you just barge into other ponies' kitchens and throw their babies around now?" he roared, getting closer to her, "What kind of horrible monster are you, huh?"

"I-I-I didn't-b-but w-wha-" Rarity stammered in response.

"And the nerve!" Mrs. Cake yelled, joining in the argument, "I should call the guards right now on you!" She hugged her twins tightly to her chest. "My poor babies were just enjoying a little snack, courtesy of your lovely sister here and her massive breasts-"

Suddenly the arguing stopped. Both adult Cakes turned to Sweetie Belle, who was grasping her enormous boobs tightly. Spotted the two ponies staring at her, she blushed and raised her hoof, waving it a little. Consequently, the boob left uncovered suddenly fired milk across the room, showering the Cakes, both young and old, in a milky rain. Sweetie Belle lost control of the other hoof, and accidentally let it blast them with milk as well. Embarrassed, she stood up and silently waddled behind Rarity, her face completely red. Rarity's face was a similar hue, unsurprisingly. A few moments later, Sweetie Belle managed to squeak, "Sorry..."

Mr. Cake and Mrs. Cake looked very blank for a while. They didn't move, not even blinking, instead just stood there, silently. Finally, the two glanced at each others' milk coated bodies.

Then, the Cakes passed out.
