Chapter 1 - a life changing experience

Lara went into the dressing room, changed her clothes into something comfier, some leggings and a crop top, and took off for her last casting of the day. She had worked as a model for the past 4 years since she was only 15 when she was scouted as she was shopping at the mall. She had the perfect model look, her eyes were big and blue, her hair was black and long and her skin was fair. She was tall, but a little short to be a model, about 5'6, but her body was perfectly proportionated and firm. She had just changed into a pair of black leggings that hugged her body perfectly and a crop top that showed her toned flat belly. As soon as she came out of the building, almost running, she ran onto Mark, her ex-boyfriend. They had met on her first year of modeling as he was also a model for the same agency and they had dated for almost 3 and a half years, breaking up just a couple months ago. He said hi and started talking to her. He was being polite and extremely nice, which made her think that he was actually over her and they could now be friends, in the end, he was always a nice guy.
As she walked to her next casting they chatted on and on and he even asked her to have some coffee and talk for a while. "Of course, in a couple of hours? After my casting?" She asked. He said yes and waited outside of the building for her to finish.
After a couple of hours, Lara was done, she had done great and they had actually told her that she had gotten the job. The day was going perfectly and now she could actually enjoy spending some time with Mark.
They walked towards the nearest cafe, the classic Starbucks. She ordered some black coffee with no sugar since it has 0 calories but lots of caffeine. They sat on a table near the window and chatted.
" Here, check out this video I just received" - He said as he pulled out his phone - "You have to listen to it, the sound it's just weird"
She pulled out her headphones and listened to the whole video. There were only pictures of fast food and lots of sweets, and the sound was odd. She gave him back the phone.
"That was a weird video... I don't know if it's seeing all that food or all the walking I did today, but I am feeling pretty hungry... I am going to grab something to eat" - She said as she stood up and walked towards the counter to order something.
She checked all the sweets in the display but could not choose what to eat, she was starving like never before. She ordered a cheese sandwich and an oreo cake and went back to her table. As soon as Mark saw the food, he knew it had worked. She would have never chosen that food, its too high in calories for her, but now that was not on her mind anymore. She ate both things rapidly as he talked. After a couple of hours there, they left and she headed home. Weirdly for her, she was feeling hungry again on her way home, she stopped at the McDonald's that right around the corner from her apartment and ordered some food. She sat alone on one of the tables and ate. Full big mac with big fries and a coke. Was that enough to fill her up? It was, but she wanted more. She stood up with her belly looking bloated and ordered the same again. She ate it in a flash. She looked down, seeing her belly looking bloated and round, but in her head, her belly looked just the same. She then went home and layed in bed.
