By the end of April, Melissa weighed 320 pounds and kept on gaining steadily in May, getting to around 340 pounds as graduation came closer. She was close to reaching her goal weight, but Melissa hadn't wasted one thought on what would happen once she got there. Alisson ensured that, as she kept Melissa stuffed and aroused all day and rewarded her piggy with mind-blowing orgasms once at home. Melissa had no time to think about anything other than her desire to grow and please Alisson.
When the last week of school started, Melissa woke up Monday morning as Alisson was standing above her with a smile on her face.
"Wake up, my piggy. Today is your special day," she said as she held up a sports bag. "You've finally recovered from your injury and are free to participate in PE class again. I've already packed your clothes for you," she grinned and placed the bag next to her.
Melissa sighed. She had dreaded this week for a while now. As much as getting humiliated turned her on, working out would be hell. Forcing her out-of-shape body to do any exercise felt terrible, and the sore muscles she got from the slightest exertion made moving around the following days torture. Especially the fact that she had to work out every day of the week caused her to feel very anxious.
Her PE class was just after lunch, so Melissa was anxious all morning and even more aware of how ridiculously fat she had gotten this year. During her lunch break, she devoured her huge portion rather quickly and sat around anxiously as she saw a girl approach her with a bag in her hand. She set the bag in front of Melissa, grinned, and said it was a little gift from Alisson.
Melissa opened it and saw that it was filled with various snacks. She immediately knew what to do and grabbed the first candy bar. Those snacks were the perfect way to take her mind off the unpleasant struggles waiting for her. She tore the wrapper off and stuffed one candy bar after another into her mouth, the pleasure of her gluttony sweeping away all of her sorrows.
Before she knew it, she had devoured every last candy bar. Leaning back and feeling her full stomach spread out, Melissa slowly returned to her senses. The ecstasy of her binge soon faded and was replaced by an even worse feeling of anxiety as Melissa realized just how full to the brim she was. She had trouble breathing even while sitting down and not moving at all. With a labored groan, she lifted herself from her seat, feeling the heaviness of her belly even more. She was already panting loudly before beginning her miserable waddle to the locker room.
By the time she reached it, Melissa was so out of breath and tired that all she wanted to do was to take a long nap. Instead, she was greeted by everyone inside staring at her in amusement, curious to see what kind of outfit she was going to embarrass herself in.
Melissa slowly stripped out of her clothes, careful not to lose balance because of her stuffed belly, and opened the bag Alisson had packed for her. She could immediately tell that the clothes inside were too small for her, just as she had expected. Melissa took out the spandex hot pants, slipped her cellulite-covered legs into them, and had to pull with all her strength to get them past her knees.
Standing still to catch her breath, she could feel they didn't manage to cover all of her fat ass, and part of it was hanging out. Besides, she knew her belly hung so low that it would cover the entire front part. The room was filled with snickering and laughter as Melissa took out the top that Alisson had packed. She put it over her head and was happy when she managed to pull it over her huge boobs. Still, the top didn't even cover a part of her belly, leaving it exposed for everyone to see what an obese mess her overeating had turned her into. As she recovered, Melissa collapsed on a bench, feeling like an actual whale. Meanwhile, everyone else was leaving the room laughing and making fun of what was to come for the school's fat piggy.

The class had already begun when Melissa finally left the locker room. She could hear everyone jogging in circles as a warm-up as she waddled around the corner.
"Well, look who's finally joining us," she heard the coach say as he looked at her in disgust and disappointment.
Melissa looked around the sports hall nervously and realized that Allison must have spread the news about her workout attempt to the whole school. The stands were full of people waiting for the spectacle. She was met with amused smiles, and cameras pointed toward her wherever she looked.
She slowly waddled inside, trying to postpone the inevitable as long as possible. Her stuffed belly weighed her down even more, and she was panting as she reached the circle everyone was running in. There was no way out now. Melissa took a final deep breath and started running, immediately feeling miserable. Her belly jiggled violently and slapped loudly against her thighs while her giant boobs bounced and hit her in the face. It was tough to move her massive thighs past each other, and she knew it didn't look like she was actually running. Instead, it looked like a slightly faster and bouncier waddle. It seemed to amuse her audience as the hall filled with laughter and cheering.
But Melissa didn't notice much of that. She also didn't see how her running was about as fast as an average person would walk, and she was being passed left and right by other students. The only thing on her mind was the agony her body was in. Her untrained legs felt the weight of every step and were already hurting badly. Her lungs were on fire as she gasped for air and felt her whole body drenched in sweat.
Lucky for her, the warm-up jogging was over after she finished her first round. Now it was time to do some stretching. While everyone started, Melissa was too occupied catching her breath and cooling down a little. Eventually, she figured doing some stretches while sitting would be best. That way, she could give her hurting legs a little break.
Once seated, she quickly realized that her fat was getting in the way with every exercise she attempted. She had gotten too inflexible to do anything properly. Still, she knew Alisson was watching and wanted her to try, so she kept going. Her fat did not only cause trouble with stretching but also cut off any air she could breathe when she bent forward. Because of that, she soon again was panting and sweating throughout. She also realized that sitting down might have looked like a good idea, but it wasn't as soon as stretching time was over. The coach had called everyone around him into a circle. While the other students quickly arrived, Melissa was still plopped on the floor, mentally preparing herself for the strain that standing up would put on her poor body.
The coach paused and shot an annoyed look her way as everyone turned around to observe her struggle to get up. Meanwhile, Melissa rolled herself over so that she was on all fours. She paused for deep breaths while the crowd took the opportunity to berate her about how much of a pig she looked. After a minute, Melissa was ready to put up one leg and, with a loud grunt, heave herself into a standing position. She felt her body cry out for another break as sweat streamed down her chubby, red face. Waddling over to the coach, she dreaded what he had planned for the rest of the class.
