Cody wasn't necessarily fat, but rather chubby. He was your typical gamer who just sat in front of his TV or his computer and played games all day, however, whenever he would have the chance, he would go and work out to even out the styles of gaming and health. Sadly, the exercise had no effect on him. He tried eating healthy, he tried not playing for a week, he even tried doing push-ups whenever he died on his game. Nothing ever worked.
He'd basically given up because nothing worked on his body. Though, his mom thought that he'd worked out and eaten healthy, it was all muscle. He considered the thought, but when he poked himself and felt the soft flesh, he frowned at the fact that he was fat. He wasn't bullied either, surprisingly. Everybody in his school knew he worked out and ate healthy. He could even outrun some of the jocks! As much respect as he got at school, he was still depressed because he couldn't get rid of his belly.
While at school, one of his friends, Jamie, found a product that she'd used when she was a little chubby herself. "What kind of milk do you drink, Cody?" She asked, sitting next to him during lunch. "Soy. Why, is that what's causing this?" He groped a piece of his fat. "No, no. It's just that I drank this milk when I was like you. No offense." She held up an ordinary milk carton that looked like she'd gotten it from a cartoon show. "You drank just... milk?" Cody was confused, it looked like a regular quart of milk to him, nothing special. "It's called 'Slim Milk'. It's like a dietary milk that'll make you lose the weight you want!" She handed him the milk carton. "I dunno, stuff like that would come in like omega packages where it has a bunch of info on the can or whatever and says like 'DRINK THIS MILK' or something." Jaime placed a hand on his shoulder, "Trust me, Cody." And she left. Cody looked down at the carton again and shrugged. He carefully placed the carton in his backpack and would drink it later when it was in his fridge.
School went by in an instant and Cody found himself walking home. He didn't live far, but he'd tried making the best of his walking by doing a bunch of jogging/running exercises on the way to his house to give him an extra workout. He arrived home and was sweaty. Naturally, he wanted to take a shower so he'd feel refreshed and clean. He took the carton of milk out of his backpack and placed it in the freezer so it would get colder faster. He went off upstairs and started the water. He took off his clothes and stepped into the shower. While he was showering, he was thinking about the milk. "Would it taste good? Is it poisoned? Will it work?" Thoughts swarmed his mind like bees, and all that thinking soon got Cody thirsty. Really thirsty. He didn't want to drink the water in the shower because it was warm and it tasted weird. He wanted that milk now.
He didn't want to rush, so he cleaned thoroughly but in a fast manner. He stepped out of the shower and dried his hair and most of his body. He wrapped the towel around his waist and proceeded downstairs to his kitchen. He opened the freezer to be met with a chilling blast of air that gave him goosebumps. He took the milk out of the freezer and opened the carton, chugging half the carton alone. "Man alive, that is good!" He started drinking more. Each gulp he took he could feel the fresh, frosty liquid down in his stomach. He didn't know if it was his imagination or the milk itself, but he felt a lot skinnier. Stopping to take a breather, Cody flinched as remnants of water in his hair dripped coldly on his neck. He took his towel off and dried his hair again. But what he didn't know was that 'dripping' was his actual hair growing down his neck.
Since he knew nobody was home, he didn't bother putting the towel back on his waist, so, he kept drinking. His body started to shrink; all of his hard earned muscles and his unwanted chub was fading away into his body, displacing themselves in the more needed areas of his body. His waist grew thinner and his hips grew wider. His legs were skinnier and started to become more shapely. He stopped to take another breather. His hands shrank down to size and his nails grew slightly longer, his feet followed. There was a small cramp on his butt and Cody almost spit his milk out by how sudden and painful it was, but it was fine. He finished the last few drops of the milk and slammed the carton down as if he just won a chugging contest. When he slammed the carton, there was a tug on his crotch. Soon enough, there was nothing there but a patch of skin. A pressure on Cody's chest hinted that he may have drank a little too fast. He pounded his chest, feeling a burp coming up. As he pounded, it seemed as if he were pounding the mounds of flesh onto place. He burped and was done with the milk.
"WOW, that was good milk!" Carly wiped her mouth. She got the towel off of her shoulder and was about to dry her hair some more, but she noticed herself naked. "Eep!" She squealed, looking around in embarrassment. She covered her chest with the towel. "I better get some clothes on..." She went upstairs and got some jeans and a shirt. She put them on and looked in the mirror. "Wow, that milk really worked out!" She posed a couple of times. "I better go tell Jaime!" Carly walked down the stairs and giddily went over to her friends house to thank her.
