Four women shared a spacious upscale apartment, they were all well-acquainted friends, and no more. Though they had all had private thoughts on becoming more, but they never fed these thoughts.
The first of these woman to return to the apartment that day was Sasha. She stood at 5'8", as she glanced over the kitchen with her hazel eyes. She squinted at a milkshake sitting out on the counter, still frosted on the outside with condensation pooling at the base.
"Oh yea, Elaine gets milkshakes on Friday." she reminded herself as she grabbed one of them, they all appeared to be the same, but this one was marked with an 'S'. Her full lips took a sip of it through it's straw. Cookies & Cream, same as always. A bit thicker than usual, but she didn't mind. She took it to her room, changed into some comfy clothes, and sat her 170lbs body at her desk, opened her laptop and found herself just staring at it as she drank down her milkshake. She shook it off, she usually didn't space out like that. She scrolled through Reddit, setting the milkshake on the edge of the desk and still drinking it. She stopped, shouldn't she have gotten a brain freeze by now?
Sasha looked down at her milkshake, only to see something she didn't expect: Her boobs on her desk. "What the?" she leaned back, brushing her dirty blonde hair from her face, then saw her thighs were bigger. Flabbergasted, Sasha jumped up from her desk chair, and felt just how much her body had changed. "How the hell?" she looked in her full length mirror to see her breasts had swollen to the size of her head, and hung down over a soft belly, newly exposed due to her now ill-fitting shirt. Her yoga pants strained to hold in her hips and ass, which spilled from the top, and her thighs threatened to tear their way out. She looked back at the milkshake, then brought it over in front of the mirror. Staring at herself she took a deep gulp of it, and saw herself grow fatter.
"What the hell kinda milkshakes did Elaine get?" Sasha said aloud as she stormed from her room with the beverage of dubious providence.

Jasmine was the second and tallest woman to return home that day, standing at 6'2". She pulled her black hair out of it's bun and let it cascade down, parting it so her brown eyes could see. She looked over and saw three milkshakes in the kitchen.
"I thought she usually got them later in the day." The 200lbs thought to herself, grabbing the vanilla milkshake marked with a 'J' without question and taking it to her room. Upon entering, she took her bra off and tossed it aside, the J-Cup tag lost among a sea of other clothes. Topless, Jasmine reclined on her bed and started watching videos on her phone, mostly old Vine compilations, taking gulps from her milkshake between laughs. She held her phone close to her face, and drank maybe too much of her milkshake. Finishing a video, she set her phone aside, wiping a few tears from her eyes as she regained her breath from laughing. She went to pick up her phone again, but was shocked to see just how much she had fattened. Her weight rested most prominently in her boobs, which had almost doubled in size as they lay heavy on her torso. However, the rest of her was not untouched by her gain. Her belly parted her breasts softly, and her shorts not uncomfortably tight as well.
"Dang it, these were already big enough! How did this even?" her hands reached up to feel them, and she gasped. They were sensitive, and her nipples felt bigger than normal, even for being engorged. "How the heck--" she started, then stopped as she felt something wet leak from her nipples. Pulling one up towards her face, she saw a small trickle of white coming out. "Milk??" she asked aloud to no one. She glared at her milkshake before grabbing it and leaving her room.

The third woman to return, Abby, sauntered into the home and smiled as she saw the milkshakes sitting on the counter. Her lithe 5'0" form silently went over and grabbed the one marked with an 'A'. Quickly scanning the room with her blue eyes, she deduced no one else was around, and scurried to her room.
"I love milkshake Fridays" she thought to herself, "chugging the whole thing and then weighing myself, mm~" she hummed, getting riled up in anticipation. She went to her bathroom and pulled out her scale. Stepping on it, "104" she read, "still the same, well hopefully this time will be different!" Abby repeated the same thing she always said to herself. She got up on her bed and slid off her shorts. She retrieved her strawberry milkshake from her nightstand, removed the lid, licking the inside clean, and started to chug it. Her other had rubbed her bloating belly and slid down to her clit, teasing it before sliding down and entering between her wet lips. She moaned as she felt her stomach fill with thick cream, eagerly gulping down more before she finished the beverage.
She licked what she could out of it, then set it aside, focusing on herself entirely. Her free hand playing with one of her nipples, when suddenly, her breast started getting softer. Her previously flat chest was getting bigger! All of her was! Her entire body was fattening right before her eyes. She withdrew her other hand from her pussy as she groped herself, fervent moans filling her room as she grew thicker and thicker, her breasts growing rapidly on her chest, quickly surpassing her head in size as streams of milk started to spray out from her hyper-sensitive nipples as her pussy soaked her sheets. Her erotic euphoria only increased more and more with her weight, her body thickening on her bed as her juices and milked soaked it through, "God fucking moo~" she moaned before her orgasm made her mind go blank and she passed into a blissful sleep.
