"Sure, you finished the cookies, but what are cookies without milk?" Lauren taunted.
The color drained from Megan's face. Though she had been able to down the entire package of cookies, the experience had left her bloated belly feeling nauseous. What it needed now was some light rest and Pepto-Bismal, not a sickening torrent of milk. Still, even if the punishment didn't end with her bent over a toilet bowl, there was still the issue of the calories. Oh, the calories. Though not nearly as weight cautious as her pudgy sister, Meg had no desire to start packing on the pounds. An entire package of cookies was already quiet fattening; an addition of milk was surely to push her past the point of weight gain, assuming she hadn't already passed it.
"Please, Lauren, no more!" she begged. "My belly can't handle it."
"Aww, what's that? Is the human snack disposal starting to have second thoughts about buying all this junk food?"
Meg, realizing her spiteful sister would never give in, lowered her head in defeat. Lauren, savoring the moment for all it was worth, slowly strutted towards the fridge. A confident, victorious grin stretched across her face from ear to ear as she ripped the pearly white door open, causing the contents inside to shake violently. She gazed inside, her eager eyes quickly locking onto the gallon jug of whole milk.
"Ah, here we are," she said as she lifted it out, "One gallon of whole milk, fresh from the supermarket. Are you ready to see how much you can handle, flatty?"
Meg kept her head lowered, refusing to acknowledge her sister. Lauren, peeved at her sister's defiance, decided to be more forceful with the next round of feeding. Jug in hand, she stomped over to her sister and grabbed the back of her hair, forcing her face upwards. Meg screamed in pain, opening her mouth long enough for Lauren to shove the circular opening inside. Her eyes became wide as the first of the thick, creamy liquid flowed from the plastic container towards the back of her throat. She held back from swallowing, letting the milk build up and her cheeks to swell outwards, before finally giving in as the pressure became too much to bear.
From a distance, you observe as the skin around her throat is rhythmically expanded and contracted, working its hardest to send the milk into her waiting stomach. A look of pain grows in Megan's eyes as ever-flowing liquid begins to fill in the space between the chewed up cookies, adding greatly to the bloating burden she had felt. It's not until she's downed around half of the jug that her belly, literally packed entirely with milk and cookies, began to expand outwards, creating a small but visible bulge that presses against her shirt.
Lauren, content with the amount, stopped the milking at just passed the half-way point.
"That wasn't so bad, now was it?"
"Ugh...please, l-let me go lay down a bit Lauren."
"Sure thing, Meg. I think we've had enough junk food for today, wouldn't ya say?"
Had she been in a better state of mind, Meg would have shot back with clever insult, but she was barely able to walk, let alone be witty. She cautiously pulled herself out of the chair, her stuffed belly pushed outwards to keep balance as Lauren placed the half-finished milk back in the fridge. Worried about your sister, you decided to inquire on her condition.
"You sure you're alright, Meg?" you ask. "You look a little pained."
"Y-yeah, I'll be alright, I just need to lay down a bit..."
She trailed off as she exited the room. With the spectacle finished, you go to leave, but were stopped as Lauren grabbed you arm.
"And just where do you think you're going? We still haven't discussed you're punishment!"
What did she want you to do?
