Chapter 1

"Should we order in pizza tonight?"

Alice glanced over at her roommate Zoe, who was browsing through a stack of takeout menus. It was December, the last week of their first semester of medical school, and they were fresh out of groceries. Take-out was their only option unless Alice felt inspired to go to the grocery store - it had probably been months since Zoe had eaten anything except for cafeteria food, take-out, or Alice's leftovers.

"Sure, let's get pizza! We might as well celebrate exams being done," replied Alice with a grin.

Zoe looked up from the stack of menus and grinned back. Alice was struck, as always, at just how beautiful her roommate was. Her long, wavy auburn hair framed a heart shaped face and set off her luminous ivory skin. She had large brown eyes, a sensual mouth, and high cheekbones. On top of all that, she had a figure that most women dreamed of - petite in stature, slender limbs, but with luscious curves. She was soft and voluptuous. She looked hot, even in scrubs.

The two roommates made a strong visual contrast. Alice was several inches taller that Zoe and a former college athlete. Every muscle was toned, her skin tanned, and her features were striking rather than soft. She wore her straight brown hair cut just below her shoulders and usually tied back to keep it out of her face, whether during exercise or anatomy lab.

As different as they were in appearance, the two roommates had become close friends over the past 6 months. They hung out together after class, explored the city on weekends, and occasionally went to parties. Alice tried to persuade Zoe to join her at the gym, with little success. Zoe claimed that her metabolism had been going strong her whole life and hadn't failed her yet.

However, the question of Zoe's metabolism had been on Alice's mind for weeks. It was hard to imagine that any woman in her mid 20s could eat a diet of pizza, donuts, and sugary iced coffee with no consequences - and in fact, Alice had begun to notice the presence of such consequences. As the weather got colder, it was hard to tell that Zoe's body had changed underneath her sweaters and winter coats. But in the privacy of their apartment, Zoe would wear sweatpants and tank tops, and it was then that Alice could see the subtle changes to Zoe's body.

It wasn't really much at first; Zoe's round, perfectly shaped ass just seemed to get a little rounder. Her thighs seemed to grow even curvier. And her breasts seemed to grow at least a cup size. But as the months went by, Alice began to notice other changes. Zoe's face grew a little fuller, her arms a bit more fleshy, and most of all, she started to accumulate a soft layer of fat on her belly.

It was the appearance of the plump belly that completely changed Alice's world. She had first spied it when Zoe was reaching to grab coffee from a high shelf in their kitchen. Her t-shirt had ridden up over her midriff, revealing a small but noticeable belly. Granted, Zoe had never had perfectly flat abs; her torso had always been cushioned by a slight layer of fat. But this was different. Her shirt rode up to expose a thick, soft roll of fat on her lower belly that had never been there before. Her naval was a deep indent in the plush, yielding flesh.

The sight her gorgeous roommate with a small, chubby belly had left Alice breathless. She had always felt attracted to Zoe, but she rationalized it as inevitable - who could not be attracted to such a beautiful girl? She was happy being roommates and friends, and nothing more. Now, she felt an uncontrollable temptation toward her roommate, and was constantly distracted by Zoe's increasingly plump body. Alice was going home for the holidays had resolved to spend her entire winter break having as much casual sex as she possibly could, in the hopes of squashing her unrequited crush.

For now, Alice had to deal with the sight of Zoe in a pair of sweats that had once been loose, but now fit too tightly in the thighs and butt. The elastic was clearly digging into her waist, and Alice could see her love handles spilling slightly over the waistband of her pants. She could even see the slightest contour of her belly pressing gently against the fabric of the shirt.

Alice shook her head slightly, trying to clear her mind of her roommates alluring body, and turned herself to the task at hand - ordering pizza. As an additional celebration, they decided to pick up a few beers from the corner store, along with some powdered donuts at Zoe's request.

A few hours later, they had gorged themselves on pizza and beer - well, Zoe had certainly gorged herself. Alice had been a little more restrained - she did have a 10k run in the morning - but she had indulged a bit on beer and was feeling pleasantly buzzed. They were about to settle into the living room to start a movie marathon when a knock came at the door.

It was Zoe's boyfriend, Jake. In many ways, he was the perfect boyfriend - tall, handsome, athletic, and pursuing a degree in exercise science. Zoe adored him, but Alice had her doubts. She had seem him act unkindly towards friends and strangers, and she felt that his behavior towards Zoe sometimes verged on controlling, almost as though she were a pretty pet that he could order around.

Jake took off his coat and gave a quick kiss to Zoe and a nod to Alice.

"Big celebration night?" he asked, gesturing to the empty pizza boxes and cans of beer.

"Well of course! We're celebrating the last day of exams," Zoe said with a mischievous smile. Her ivory skin was slightly flushed from the alcohol. She tried to fling her arms around Jake's neck, but he held her back, looking her up and down.

"Well babe, I hope you enjoyed yourself tonight. Starting tomorrow you're on a new diet and exercise regiment, remember? I sent you all the details last week. I want you in the gym every day from now until the start of spring semester."

Alice rolled her eyes, and interjected, "Jake, that's hardly reasonable. You know that Zoe is staying on campus to work on an experiment with her advisor, it's not like she's going to have tons of extra hours to work out."

"Besides," Zoe pouted, "I don't think I need to lose any weight. My body looks the same as it always has."

At that, Jake narrowed his eyes and spun Zoe in his arms. Using one forearm to keep her upper body braced against his chest, he used his free hand to pull Zoe's shirt up, exposing her belly.

Alice tried not to stare, but it was impossible. The thick, soft roll of Zoe's lower belly and love handles spilled over her tight waistband. Her navel was a deep indent in the soft fat. Her upper belly was plumper than it had been. If she continued to gain weight, she would surely have a full pot belly. Alice felt breathless at the thought of her roommate with an even chubbier, rounder belly.

Jake clearly did not share Alice's sentiment. Zoe blushed furiously and started to protest, but he held her tightly in place. She struggled against his hold, but it only made her belly fat jiggle. The blush from Zoe's face crept down and tinged the pale soft skin of her belly.

"I'm just bloated from the beer, Jake," Zoe said, trying and failing to sound casual. "You know that my belly will be flat again in the morning."

Keeping her shirt rucked up, Jake reached a hand down and tightly pinched the thickest part of Zoe's lower belly. Giving it her belly a firm shake, he said "Don't play games with me, Zoe. Do you think I could squeeze your gut like this if you were just bloated? I know you've been pigging out these past couple months, and now you have all this belly fat to show for it."

As he spoke, Jake reached his other hand down to grab the other side of her belly. Zoe didn't even try to protest or escape - she merely watched, dazed, as Jake used both hands to squeeze her belly fat inward. Then he placed both hands underneath her lower belly roll and bounced it violently up and down. Tears of humiliation gathered in the corners of Zoe's eyes as her boyfriend jiggled, squeezed, and poked her exposed belly fat.

After a moment, Alice spoke up. "Jake, can you please leave her alone? It's been a stressful semester, we were just trying to celebrate a little. Why don't we just go and watch a movie or something?"

Jake glanced up at Alice and shook his head. "No thanks, Alice. This is the last time I'll be seeing Zoe in a month, and I plan on enjoying myself. Well, enjoying myself as much as I can with this fat cow."

He released Zoe and grabbed her wrist, leading her towards her bedroom. Zoe glanced back at Alice, an apology in her eyes, her cheeks still red from shame. As the walked down the hall, Alice heard Jake say, "We'll only be doing it doggy style tonight. I don't want to watch your fat belly jiggling up and down while I fuck you."

After they disappeared into Zoe's room, Alice stood for a long moment in the kitchen, processing what she had just seen. She couldn't believe that Jake humiliated his own girlfriend like that, and Zoe had barely even tried to speak up for herself. Alice wondered whether their relationship was abusive - would she have to intervene on Zoe's behalf?

At the same time, she couldn't stop herself from remembering the moment when Jake had exposed Zoe's soft midriff, the way that her fat had bounced as it was released from her shirt. The way her soft, pliable fat rolls had looked as they were pinched and bounced, the way her navel had looked when Jake squeezed the sides of her doughy belly. It was all too much for Alice - she couldn't stop picturing Zoe on her knees as Jake fucked her from behind, her belly fat hanging loosely and jiggling violently with each thrust.

Worst of all, Alice couldn't stop imagining herself walking up Zoe, pushing her against a wall, and slipping a hand up her shirt. She imagined how Zoe's soft, warm belly would yield to her touch, how she would press her fingers deep into that pliable flesh. How it would feel to hear Zoe's soft gasp in her ear as Alice tickled and teased her lower belly roll, as she gently pressed a finger into that deep navel, as she whispered into Zoe's ear, "You're a greedy fat girl, aren't you?"

It was all too much. Alice went to her room, trying to ignore the sounds of Zoe's whimpers and moans through the door.
